Definitions
- the present disclosure relates to a surgical apparatus having a buttress material incorporated therewith. More particularly, the present disclosure relates to a surgical stapling apparatus including a detachable surgical buttress and/or an endoscopic surgical stapling apparatus that includes a detachable surgical buttress.
- Surgical devices for grasping or clamping tissue between opposing jaw structure and then joining tissue by surgical fasteners are well known in the art.
- a knife is provided to cut the tissue which has been joined by the fasteners.
- the fasteners are typically in the form of surgical staples but two-part polymeric fasteners can also be utilized.
- Instruments for this purpose can include two elongated jaw members which are respectively used to capture or clamp tissue.
- one of the jaw members carries a staple cartridge which houses a plurality of staples arranged in at least two lateral rows while the other jaw member has an anvil that defines a surface for forming the staple legs as the staples are driven from the staple cartridge.
- the stapling operation is effected by cam members that travel longitudinally through the staple cartridge, with the cam members acting upon staple pushers to sequentially eject the staples from the staple cartridge.
- a knife can travel between the staple rows to longitudinally cut and/or open the stapled tissue between the rows of staples.
- Such instruments are disclosed, for example, in U.S. Pat. No. 3,079,606 and U.S. Pat. No. 3,490,675.
- FIG. 1 Another stapler disclosed in U.S. Pat. No. 3,499,591 also applies a double row of staples on each side of the incision.
- This patent discloses a surgical stapler that has a disposable loading unit in which a cam member moves through an elongate guide path between two sets of staggered staple carrying grooves. Staple drive members are located within the grooves and are positioned in such a manner so as to be contacted by the longitudinally moving cam member to effect ejection of the staples from the staple cartridge of the disposable loading unit.
- Other examples of such staplers are disclosed in U.S. Pat. Nos. 4,429,695 and 5,065,929.

No. 8,157,151), commonly assigned U.S. application Ser. No. 11/241,267, filed on Sep. 30, 2005 (U.S. Patent Publication No. 2006/0085034, now U.S. Pat. No. 7,938,307), and U.S. application Ser. No. 11/248,846, filed on Oct. 12, 2005 (U.S. Patent Publication No. 2006/0135992, now U.S. Pat. No. 7,823,592), the entire contents of each of which is incorporated herein by reference.
- Surgical buttresses “B” may be fabricated from a suitable biocompatible and bioabsorbable material. Surgical buttresses “B” may be fabricated from a non-absorbent material which does not retain fluid. Surgical buttresses “B” may be fabricated from “BIOSYN” made from GLYCOMER 631 (a block copolymer), a synthetic polyester composed of glycolide, dioxanone and trimethylene carbonate.
- One block of the resulting copolymer contains randomly combined units derived from p-dioxanone (1,4-dioxan-2-one) and trimethylene carbonate (1,3-dioxan-2-one).
- the second block of the copolymer contains randomly combined units derived from glycolide and p-dioxanone.
- the resulting polyester is an ABA triblock terpolymer possessing about 60% glycolide, about 14% dioxanone, and about 26% trimethylene carbonate.
- surgical buttresses “B” may be constructed and/or fabricated, from the above-identified materials, as a non-woven, absorbable felt and the like.
- surgical buttresses “B1, B2” may be further attached to the tissue contacting/facing surface of cartridge assembly 18 and/or anvil assembly 20 of surgical stapling apparatus 10 in a number of different ways.
- a roughness of a tissue facing side of surgical buttresses “B1, B2” may be minimized, thereby reducing friction between tissues and the surgical buttresses “B1, B2” during tissue manipulation; a flexing of the surgical buttresses “B1, B2” between attachment points thereof may be minimized, thereby limiting movement where the surgical buttresses “B1, B2” is not fastened to cartridge assembly 18 and/or anvil assembly 20 ; a shape of each surgical buttresses “B1, B2” may be modified to conform to the topography of tissue facing surface of cartridge assembly 18 and/or anvil assembly 20 ; and/or increase a width of a profile of surgical buttresses “B1, B2” to be wider than a width of the respective cartridge assembly 18 and/or anvil assembly 20 widths so that some lateral shifting of surgical buttresses “B1, B2” can occur without compromising reinforcement of the entire staple line.
- the surface roughness of the material of surgical buttresses “B1, B2” may be minimized by any number of means including calendaring, applying heat and pressure, adding a lubricious coating, or forming the material on a flat surface.
- the material of surgical buttresses “B1, B2” could be produced by blowing fibers onto a smooth heated belt to encourage relaxation of the fibers to conform to the heated surface.
- Minimizing buttress roughness reduces the interaction of the material of surgical buttresses “B1, B2” when being moved across tissue, thus reducing forces exerted on the surgical buttresses “B1, B2” which lead to movement of surgical buttresses “B1, B2”.
- flexing or the flexibility of the material of surgical buttresses “B1, B2” may be minimized by increasing the material density, basis weight, or choosing a base material that has a high Young's modulus. In the case of melt blown synthetic fabrics, this can also be accomplished by calendaring with heated rollers to increase intra fiber bonding and to increase fiber packing Less material flexing equates to the surgical buttresses “B1, B2” moving less when forces are exerted thereon during tissue manipulation.
- a topography of the surgical buttresses “B1, B2” may be shaped through heat and pressure when on the respective cartridge assembly 18 and/or anvil assembly 20 , or staple reload, so that the surgical buttresses “B1, B2” conforms to the shape of the tissue facing surface of the respective cartridge assembly 18 and/or anvil assembly 20 .
- This concept could include deforming the topography of the surgical buttresses “B1, B2” through pressure with a patterned press in such a way that the material is slightly deformed locally into the staple retaining pockets in the cartridge assembly 18 and into the staple forming pockets on the anvil assembly 20 and also into the knife slots in the anvil assembly 20 and cartridge assembly 18 . These local deformations would increase the contact area between the buttress and cartridge and anvil surfaces and would thus make it more difficult to displace the surgical buttresses “B1, B2” during tissue manipulation.
- a profile of the surgical buttresses “B1, B2” may be made wider so that its edges (lateral or otherwise) extend partially around the circumference and beyond a lateral side edge of the respective cartridge assembly 18 and/or anvil assembly 20 , or staple reload. This could be done in combination with heat and pressure to ensure conformance of the material of the surgical buttresses “B1, B2” to the tissue facing surface of the respective cartridge assembly 18 and/or anvil assembly 20 so that shifting (i.e., lateral shifting) is hindered. Additionally, if any shifting were to occur the extra width of the profiles of the surgical buttresses “B1, B2” would help ensure that the entire staple line is reinforced with buttress.
- the surgical buttresses “B” may be fabricated from any biodegradable and/or non-biodegradable material, including polymers, that can be used in surgical procedures.
- biodegradable as used herein is defined to include both bioabsorbable and bioresorbable materials. By biodegradable, it is meant that the material decomposes, or loses structural integrity under body conditions (e.g., enzymatic degradation or hydrolysis) or is broken down (physically or chemically) under physiologic conditions in the body, such that the degradation products are excretable or absorbable by the body.
- Absorbable materials are absorbed by biological tissues and disappear in vivo at the end of a given period, which can vary, for example, from hours to several months, depending on the chemical nature of the material. It should be understood that such materials include natural, synthetic, bioabsorbable, and/or certain non-absorbable materials, as well as combinations thereof.
- Representative natural biodegradable polymers which may be used to form the medical devices include: polysaccharides such as alginate, dextran, chitin, chitosan, hyaluronic acid, cellulose, collagen, gelatin, fucans, glycosaminoglycans, and chemical derivatives thereof (substitutions and/or additions of chemical groups including, for example, alkyl, alkylene, amine, sulfate, hydroxylations, carboxylations, oxidations, and other modifications routinely made by those skilled in the art); catgut; silk; linen; cotton; and proteins such as albumin, casein, zein, silk, soybean protein; and combinations such as copolymers and blends thereof, alone or in combination with synthetic polymers.

Description
- The present application claims the benefit of, and priority to, U.S. Provisional Application No. 61/770,855, filed on Feb. 28, 2013 the entire disclosure of which is incorporated by reference herein.
- The present application relates to U.S. patent application Ser. No. 13/729,144, filed on Dec. 28, 2012, now U.S. Pat. No. 8,631,989, which is a Continuation Application which claims the benefit of and priority to U.S. application Ser. No. 13/097,194, filed on Apr. 29, 2011, now U.S. Pat. No. 8,365,972, which is a Continuation-In-Part Application which claims the benefit of and priority to U.S. application Ser. No. 12/414,943, filed on Mar. 31, 2009, now U.S. Pat. No. 8,011,550, the entire content of each of which is incorporated herein by reference.
- 1. Technical Field
- The present disclosure relates to a surgical apparatus having a buttress material incorporated therewith. More particularly, the present disclosure relates to a surgical stapling apparatus including a detachable surgical buttress and/or an endoscopic surgical stapling apparatus that includes a detachable surgical buttress.
- 2. Background of Related Art
- Surgical devices for grasping or clamping tissue between opposing jaw structure and then joining tissue by surgical fasteners are well known in the art. In some instruments a knife is provided to cut the tissue which has been joined by the fasteners. The fasteners are typically in the form of surgical staples but two-part polymeric fasteners can also be utilized.
- Instruments for this purpose can include two elongated jaw members which are respectively used to capture or clamp tissue. In certain surgical staplers, one of the jaw members carries a staple cartridge which houses a plurality of staples arranged in at least two lateral rows while the other jaw member has an anvil that defines a surface for forming the staple legs as the staples are driven from the staple cartridge. The stapling operation is effected by cam members that travel longitudinally through the staple cartridge, with the cam members acting upon staple pushers to sequentially eject the staples from the staple cartridge. A knife can travel between the staple rows to longitudinally cut and/or open the stapled tissue between the rows of staples. Such instruments are disclosed, for example, in U.S. Pat. No. 3,079,606 and U.S. Pat. No. 3,490,675.
- Another stapler disclosed in U.S. Pat. No. 3,499,591 also applies a double row of staples on each side of the incision. This patent discloses a surgical stapler that has a disposable loading unit in which a cam member moves through an elongate guide path between two sets of staggered staple carrying grooves. Staple drive members are located within the grooves and are positioned in such a manner so as to be contacted by the longitudinally moving cam member to effect ejection of the staples from the staple cartridge of the disposable loading unit. Other examples of such staplers are disclosed in U.S. Pat. Nos. 4,429,695 and 5,065,929.
- Each of the instruments described above is designed for use in surgical procedures in which surgeons have direct manual access to the operative site. However, in endoscopic or laparoscopic procedures, surgery is performed through a small incision or through a narrow cannula inserted through small entrance wounds in the skin. In order to address the specific needs of endoscopic and/or laparoscopic surgical procedures, endoscopic surgical stapling devices have been developed and are disclosed in, for example, U.S. Pat. No. 5,040,715 (Green, et al.); U.S. Pat. No. 5,307,976 (Olson, et al.); U.S. Pat. No. 5,312,023 (Green, et al.); U.S. Pat. No. 5,318,221 (Green, et al.); U.S. Pat. No. 5,326,013 (Green, et al.); U.S. Pat. No. 5,332,142 (Robinson, et al.); and U.S. Pat. No. 6,241,139 (Milliman et al.), the entire contents of each of which are hereby incorporated herein by reference.
- Tyco Healthcare Group, LP, the assignee of the present application, has manufactured and marketed endoscopic stapling instruments, such as the Multifire ENDO GIA™. 30 and Multifire ENDO GIA™. 60 instruments, for a number of years. These instruments include a surgical stapling apparatus and a loading unit. Typically, the loading unit is attached to the apparatus immediately prior to surgery. After use, the loading unit can be removed from the apparatus and a new loading unit can be fastened to the apparatus to perform additional stapling and/or cutting operations. These instruments have provided significant clinical benefits. Nonetheless, improvements to these instruments are still desirable.
- When stapling relatively thin or fragile tissues, it is important to effectively seal the staple line against air or fluid leakage. Additionally, it is often necessary to reinforce the staple line against the tissue to prevent tears in the tissue or pulling of the staples through the tissue. One method of preventing tears or pull through involves the placement of a biocompatible fabric reinforcing material, or “buttress” material, between the staple and the underlying tissue. In this method, a layer of buttress material is placed against the tissue and the tissue is stapled in conventional manner. In another method, the buttress material is positioned on the stapling instrument itself prior to stapling the tissue. An exemplary example of this is disclosed in U.S. Pat. No. 5,542,594 to McKean et al., the entire content of which is incorporated herein by reference. In McKean et al., a tube of buttress material is slipped over the jaw of the stapler. The stapler is then actuated to staple the subject tissue and secure the buttress material between the tissue and staple line to reinforce the tissue and staple line.
- Buttress materials which are either pre-loaded or are an after-market add-on, for endomechanical or open mechanical surgical stapling apparatus, may shift in position relative to a stapler reload cartridge assembly and anvil assembly to which they are attached during grasping and manipulation of tissue by the surgical stapling apparatus. If the shifting of the buttress material is pronounced and is not corrected by the surgeon before firing the surgical stapling apparatus, then staples may form outside the perimeter or width of the buttress material thereby reducing the benefits of having the entire staple line reinforced by the buttress material.
- Accordingly, a need exists to systems and methods for securing a buttress material to the tissue contacting/facing surface of a cartridge assembly and/or anvil assembly of a surgical stapling apparatus, whereby the buttress material remains secured in place over top of the staple retaining slots and/or staple forming pockets, along an entire length thereof.
- Additionally, a need exists to design or modify the mechanical and physical properties of the buttress material to reduce the impact of material shifting on the stapler reload cartridge assembly and anvil assembly.

Then, a first end of a surgical suture “S1” is inserted into one of the pair ofdistal recesses 70 e and a second end of surgical suture “S1” is extended across the surgical anvil buttress “B1” (seeFIG. 2 ) and inserted into the other of the pair ofdistal recesses 70 e. It is contemplated that the first end of surgical suture “S1” may include a knot, stop or the like (not shown) sized so as to not pass through the narrower recess of the distal pair ofrecesses 70 e. - With the second end of the surgical suture “S1” disposed in the pair of
distal recesses 70 e, and with the surgical suture “S1” pulled taught across the surgical anvil buttress “B”, a tool (not shown) is inserted througharcuate slot 75 a ofguide plate 75 and engaged with an opening provided in thepin 77 d ofrelease bar 77 c. With reference toFIGS. 6 and 7 , the tool is then manipulated to move through or alongarcuate slot 75 a ofguide plate 75, thereby actuating or movingrelease bar 77 c and rotatingeccentric cam 77 a. Aseccentric cam 77 a is rotated,boss 77 b is rotated around the pivot axis ofeccentric cam 77 a and acts on the walls ofelongate slot 76 b ofanchor bar 76 thereby causinganchor bar 76 to pivot. Asanchor bar 76 is pivoted,finger 76 c thereof is caused to extend into or overlies one of thedistal recesses 70 e and to pinch the second end of the surgical suture disposed therewithin. Meanwhile,release bar 77 c has been moved to a position extending acrossknife slot 70 b ofanvil plate 70.Suture release assembly 74 is now in the locking or anchoring configuration, as described above. Thedistal recess 70 e that cooperates with thefinger 76 c is desirably relatively wide so as to allow the suture “S1” to easily pass into and out of therecess 70 e when the 76 anchor bar is away from therecess 70 e. The otherdistal recess 70 e, arranged on the opposite lateral side of theanvil plate 70, may be the same size, or may be small enough to cinch the suture “S1” and hold the suture in place to facilitate assembly. - In operation, with surgical anvil buttress “B1” secured against the lower surface of
anvil plate 70, during firing ofsurgical stapling apparatus 10, asdrive assembly 50 is advanced (i.e., moved from a proximal-most position to a distal-most position),knife blade 66 slices through a central section of the proximal suture “S2”, thereby freeing the proximal end of the surgical anvil buttress “B1” fromanvil assembly 20. During use, as the firing stroke ofsurgical stapling apparatus 10 is nearing completion and asdrive assembly 50 approaches a distal end ofknife slot 70 b ofanvil plate 70, as seen inFIG. 9 , drive assembly 50 contacts releasebar 77 c, urgingrelease bar 77 c and, in turn,eccentric cam 77 a to rotate about the pivot axis thereof. Aseccentric cam 77 a is rotated,boss 77 b is rotated around the pivot axis ofeccentric cam 77 a and acts on the walls ofelongate slot 76 b ofanchor bar 76 thereby causinganchor bar 76 to pivot. Asanchor bar 76 is pivoted,finger 76 c thereof is caused to move away from the relatively widerdistal recess 70 e and to release the second end of the surgical suture “S” disposed therewithin. With the second end of surgical suture “S” released or free, the distal end of the surgical anvil buttress “B1” is free to separate from the tissue contacting surface ofanvil plate 70. - As seen in
FIGS. 1 and 2 ,cartridge assembly 18 includes acarrier 80 defining anelongated support channel 80 a.Elongated support channel 80 a ofcarrier 80 receives astaple cartridge 82 therein. Corresponding tabs and slots formed alongstaple cartridge 82 andcarrier 80 function to retainstaple cartridge 82 withincarrier 80. A pair of support struts formed on and extending fromstaple cartridge 82 are positioned to rest on side walls ofcarrier 80 to further stabilizestaple cartridge 82 withinsupport channel 80 a ofcarrier 80.Staple cartridge 82 includesretention slots 82 a formed therein for receiving a plurality offasteners 84 and pushers 86. A plurality of spaced apartlongitudinal slots 82 b extend throughstaple cartridge 82 to accommodateupstanding cam wedges 90 a of anactuation sled 90. Theactuation sled 90 includes a central upstanding wedge orwall 90 b.Central wall 90 b defines a distal notch orshoulder 90 c formed therein (SeeFIG. 2 ). - A central
longitudinal slot 82 c is formed in and extends along the length ofstaple cartridge 82 to facilitate passage ofcentral wall portion 62 ofhead 60 therethrough. During operation ofsurgical stapler 10,actuation sled 90 translates throughlongitudinal slots 82 b ofstaple cartridge 82 to advancecam wedges 90 a into sequential contact withpushers 92, to causepushers 92 to translate vertically withinretention slots 82 a and urge fasteners 84 (e.g., staples) fromslots 82 a into the staple forming cavities 70 a ofanvil plate 70 ofanvil assembly 20. - With continued reference to
FIGS. 1 and 2 ,staple cartridge 82 defines a proximal pair ofrecesses 82 e formed near a proximal end thereof and disposed, one each, on opposed sides oflongitudinal slot 82 c.Staple cartridge 82 further defines a distal pair ofrecesses 82 f formed near a distal end thereof and disposed, one each, on opposed sides oflongitudinal slot 82 c. In one embodiment, at least one of the recesses of each of the proximal pair ofrecesses 82 e and the distal pair ofrecesses 82 f is preferably non-circular and constricting or otherwise arranged so as to frictionally engage and/or pinch an anchor “S”. - As seen in
FIGS. 1 and 2B ,cartridge assembly 18 further includes a surgical cartridge buttress “B2”, pledget or the like operatively secured to an upper surface or tissue contacting surface ofstaple cartridge 82, by anchors “S3” and “S4”, to overlie at least some ofstaple pockets 82 a and/or at least a portion of a length oflongitudinal slot 82 c. In particular, an anchor “S4” is cinched around a proximal portion of surgical cartridge buttress “B2” and each of the proximal pair ofrecesses 82 e and an anchor “S3” is cinched around a distal portion of the surgical cartridge buttress “B2” and each of the distal pair ofrecesses 82 f. - In one particular embodiment, a first end of each anchor “S” includes a knot, stop or the like (not shown) sized so as to not pass through one recess of the proximal pair of
recesses 82 e and a second end of each anchor “S” passes over, and transversely across, surgical cartridge buttress “B2”, at least once, and back through the other recess of the proximal pair ofrecesses 82 e. For example, the second end of each anchor “S” may be pinched or cinched in the other recess of the proximal pair ofrecesses 82 e so as to anchor the second end of the anchor “S” and secure the surgical cartridge buttress “B2” against the tissue contacting surface ofstaple cartridge 82. Similarly, an anchor “S3” is used to extend transversely across surgical cartridge buttress “B2” and into engagement with the distal pair ofrecesses 82 f. - In a further embodiment, the release assembly is arranged to cut the suture “S.” The
arcuate slot 75 a on theguide plate 75 extends in the opposite direction so that it is arranged to drive theanchor bar 95 toward the suture “S.” The surface of theanchor bar 76 that faces the suture S includes a sharpened edge and cuts the suture when actuated by the drive assembly. - Surgical cartridge buttress “B2” includes a proximal pair of notches formed in side edges aligned with the proximal pair of
recesses 82 e ofstaple cartridge 82, a distal pair of notches formed in side edges thereof aligned with the distal pair ofrecesses 82 f ofstaple cartridge 82, and a proximal notch formed in a proximal edge thereof aligned withlongitudinal slot 82 c when surgical cartridge buttress “B2” is secured tostaple cartridge 82. Surgical cartridge buttress “B2” further includes a tongue or tab extending from a distal edge thereof to facilitate with the attachment of surgical cartridge buttress “B2” tostaple cartridge 82 during the assembly process. It is contemplated that a width of surgical cartridge buttress “B2” may be reduced in a proximal portion thereof. It is further contemplated that the tongue is removed from surgical cartridge buttress “B2” following securement of surgical cartridge buttress “B2” tostaple cartridge 82 and prior to packaging or shipment. - As seen in FIGS. 2 and 10-14,
cartridge assembly 18 further includes acartridge release assembly 94 supported in and near a distal end ofstaple cartridge 82.Release assembly 94 includes a lock oranchor bar 95 pivotally connected tostaple cartridge 82.Anchor bar 95 includes abody portion 95 a having afinger 95 b extending from an edge thereof.Finger 95 b is in operative registration with one of the distal pair ofrecesses 82 f, preferably, the one of the distal pair of recesses having the relatively larger width dimension. -
Release assembly 94 further includes an anchorbar actuation member 97 pivotally connected to anchor bar 95 (as seen inFIGS. 11 and 12 ).Actuation member 97 includes afirst cam surface 97 a located along a proximal edge ofactuation member 97 and extending across centrallongitudinal slot 82 c ofstaple cartridge 82, and a secondeccentric cam surface 97 b extending distally and laterally fromactuation member 97 in close proximity to the one of the distal pair ofrecesses 82 f that is operatively associated withfinger 95 b ofanchor bar 95. First cam surface 97 a ofactuation member 97 is substantially arcuate or convex.Actuation member 97 defines an aperture oropening 97 c configured and dimensioned to receive apin 95 c ofanchor bar 95 therein so as to anchorbar 95 andactuation member 97 to pivot or rotate relative to one another. - In operation, rotation of
actuation member 97 in a first direction, about its pivot point, results insecond cam surface 97 b pressing against asurface 82 g (seeFIGS. 13 and 14 ) ofstaple cartridge 82 and thus movingfinger 95 b at least partially over and/or across the one of the distal pair ofrecesses 82 f associated therewith. - As seen in
FIG. 13 ,suture release assembly 94 includes a locking or anchoring configuration whereinfirst cam surface 97 a ofactuation member 97 extends into and across centrallongitudinal slot 82 c ofstaple cartridge 82, whereinsecond cam surface 97 b ofactuation member 97 is pressed againstsurface 82 g ofstaple cartridge 82, and thusfinger 95 b ofanchor bar 95 extends into or overlies the respective one of the pair ofdistal recesses 82 f in operative registration therewith.Fastener release assembly 94 may be maintained in the locking or anchoring configuration by way of a biasing member or a detent that engagesactuation member 97 in a manner so as to keepactuation member 97 in the locked or anchoring configuration. When in such a locked or anchoring configuration, the suture “S3” may be urged intorecess 82 f ofstaple cartridge 82. It is contemplated thatsuture release assembly 94 may include a friction fit or snap fit feature for maintaining and/or retainingsuture release assembly 94 in the locking or anchoring configuration at all times following the manufacturing/assembly process and prior to a complete firing ofsurgical stapling apparatus 10. - As seen in
FIGS. 12 and 14 ,suture release assembly 94 includes an open or release configuration whereinfinger 95 b ofanchor bar 95 does not extend into or overlie the respective one of the pair ofdistal recesses 82 f in operative registration therewith,first cam surface 97 a ofactuation member 97 does not extend into and across centrallongitudinal slot 82 c ofstaple cartridge 82, andsecond cam surface 97 b ofactuation member 97 is not pressed againstsurface 82 g ofstaple cartridge 82. -
Suture release assembly 94 is used by a manufacturer during the assembly process ofsurgical stapling apparatus 10 to secure, with an anchor, surgical suture, or tether “S”, a surgical cartridge buttress “B2” (seeFIG. 2 ) to a tissue contacting surface of thestaple cartridge 82, and by the end user ofsurgical stapling apparatus 10 to automatically release or free the surgical cartridge buttress “B2” from the tissue contacting surface of thestaple cartridge 82 upon a complete firing of thesurgical stapling apparatus 10. - With reference to
FIGS. 10-14 , during the manufacturing process, withsuture release assembly 94 in the open or release configuration, a surgical cartridge buttress “B2” is laid over the tissue contacting surface ofstaple cartridge 82. Then, a first end of a surgical suture “S” is inserted into the relatively narrower of the pair ofdistal recesses 82 f and a second end of surgical suture “S” is extended across the surgical cartridge buttress “B2” and inserted into the relatively wider of the pair ofdistal recesses 82 f. It is contemplated that the first end of surgical suture “S” may include a knot, stop or the like (not shown) sized so as to not pass through the narrower recess of the distal pair ofrecesses 82 f. - As seen in
FIG. 11 ,staple cartridge 82 includes an access opening 83 formed therein which is used to insert and receivesuture release assembly 94 therein and to provide access toactuation member 97. With the second end of the surgical suture “S” disposed in the relatively wider of the pair ofdistal recesses 82 f, and with the surgical suture “S” pulled taught across the surgical cartridge buttress “B2,”actuation member 97 is rotated about the pivot axis causingfirst cam surface 97 a ofactuation member 97 to extend into and across centrallongitudinal slot 82 c ofstaple cartridge 82 and causingsecond cam surface 97 b ofactuation member 97 to press againstsurface 82 g (seeFIGS. 13 and 14 ) ofstaple cartridge 82. In so doing,anchor bar 95 is pivoted by an amount sufficient forfinger 95 b ofanchor bar 95 to extend into or overlies the respective one of the pair ofdistal recesses 82 f in operative registration therewith thereby pinch the second end of the surgical suture disposed therewithin.Suture release assembly 94 is now in the locking or anchoring configuration, as described above. - In operation, with surgical cartridge buttress “B1” secured against the tissue contacting surface of
staple cartridge 82, during firing ofsurgical stapling apparatus 10, asdrive assembly 50 is advanced (i.e., moved from a proximal-most position to a distal-most position),knife blade 66 slices through a central section of the proximal suture “S4”, thereby freeing the proximal end of the surgical cartridge buttress “B2” fromstaple cartridge 82. During use, as the firing stroke ofsurgical stapling apparatus 10 is nearing completion and asdrive assembly 50 approaches a distal end of centrallongitudinal slot 82 c ofstaple cartridge 82, as seen inFIG. 14 ,drive assembly 50 contactsfirst cam surface 97 a ofactuation member 97, urgingactuation member 97 to rotate.Second cam surface 97 b ofactuation member 97 also rotates about the pivot axis ofpivot pin 95 c thereof. As eccentricsecond cam surface 97 b is rotated about the pivot axissecond cam surface 97 b, the distance between thepivot pin 95 c and thesurface 82 g ofstaple cartridge 82 is reduced thereby pivotinganchor bar 95 aboutpivot pin 95 c. Asanchor bar 95 is pivoted,finger 95 c thereof is caused to move away from the relatively widerdistal recess 82 f and to release the second end of the surgical suture “S” disposed therewithin. With the second end of surgical suture “S” released or free, the distal end of the surgical cartridge buttress “B2” is free to separate from the tissue contacting surface ofstaple cartridge 82. The distal recesses 82 f that is in operative registration withfinger 95 b ofanchor bar 95 is dimensioned so that, notwithstanding the rotation ofanchor bar 95, the suture “S3” is not cinched therewithin. - As
drive assembly 50 is advanced from the proximal position to the distal position,knife blade 66 thereof slices or cuts longitudinally through both surgical anvil buttress “B1” and surgical cartridge buttress “B2”, thereby dividing the buttresses “B1, B2” substantially in half. Additionally, asdrive assembly 50 is advanced from a proximal-most position to a distal-most position,upstanding cam wedges 90 a ofactuation sled 90 actuatespushers 92, to causepushers 92 to translate vertically withinretention slots 82 a andurge fasteners 84 fromslots 82 a. As fasteners 84 (e.g., staples) are urged fromslots 82 a ofstaple cartridge 82, legs offasteners 84 penetrate and pass through both surgical anvil buttress “B1” and surgical cartridge buttress “B2”, through any tissue (not shown) interposed between surgical anvil buttress “B1” and surgical cartridge buttress “B2”, and are formed against or within staple forming cavities 70 a ofanvil plate 70 ofanvil assembly 20. Buttresses “B1, B2” preferably include perforations that divide the buttresses and facilitate removal of the apparatus from the tissue. - According to the present disclosure, surgical anvil buttress “B1” and/or surgical cartridge buttress “B2” is pre-loaded (i.e., from the manufacturer) onto
anvil assembly 20 orcartridge assembly 18, respectively, of theloading unit 16. After the loading unit is fired, an additional unfired loading unit, with or without buttresses “B”, can be loaded onto the surgical apparatus. In certain embodiments, the replaceable loading unit is a removable cartridge that can be inserted into support channel ofcarrier 80. A buttress and release assembly may be pre-loaded onto the removable cartridge and means for the user of the surgical apparatus to load a buttress onto the anvil assembly can be provided. For example, a buttress having an adhesive can be used. Additional or replacement buttresses “B” foranvil assembly 20 and/orcartridge assembly 18 may be secured to eitheranvil assembly 20 orcartridge assembly 18 as needed or desired. - In a further embodiment, the release assembly may be arranged to cut the suture “S.” The
cam surface 97 b on theactuation member 97 may be arranged to cam theanchor bar 95 toward the suture “S.” The surface of theanchor bar 97 that faces the suture “S” may include a sharpened edge and may cut the suture when actuated by the drive assembly. - Turning now to

- In further embodiments, recesses 570 d, 570 e, 572 b are provided with differently-shaped slots and configurations to facilitate the insertion and/or release of a suture “S” (not shown) in a variety of circumstances. While the following embodiments illustrate a recess on the distal end of
cover plate 572, it is contemplated that these configurations may be applied equally to recesses on theanvil plate 570. - Referring now to
FIG. 47 , a recess 572 f is shown having a uniform width central portion 572 f 1, an expanding or widening mouth portion 572 f 2 disposed at one end of central portion 572 f 1 and opening out beyond a side edge ofcover plate 572, and a circular head portion 572 f 3 disposed at an opposite end of central portion 572 f 1.

Recess 572 g is configured to engage a suture “S” (not shown) at an angle rather than substantially transverse to a side edge ofcover plate 572 as in previous embodiments. Recess 572 g prevents a suture “S” (not shown) from sliding out ofrecess 572 g in a path substantially transverse to a side edge ofcover plate 572. This may be particularly beneficial during the operation ofsurgical stapling apparatus 10, as theanvil assembly 520 is advanced through tissue. - Referring to
FIG. 49 , an embodiment of arecess 572 h is shown having a uniform widthcentral portion 572 h 1, an expanding or wideningmouth portion 572 h 2 disposed at one end ofcentral portion 572 h 1 and opening out beyond a side edge ofcover plate 572, and anenlarged head portion 572 h 3 disposed at an opposite end ofcentral portion 572 h 1.Central portion 572 h 1 ofrecess 572 h defines a first width W1h, andenlarged head portion 572 h 3 defines a second width W2h that is larger than first width W1h. Disposed withincentral portion 572 h 1 are a plurality ofbarbs 572 h 1a such that upon insertion of a suture “S” (not shown) into arecess 572 h, the edges of 572 h 1b engage suture “S” (not shown) so that it is restricted from motion away from theenlarged head portion 572 h 3. - Turning to
FIG. 50 , disposed on an inner wall of therecess 572 h within theelongated head portion 572 h 3 are a pair ofsteppes 572 h 3a,3b.Steppes 572 h 3a,b are defined by ledges that are offset along a line extending through theelongated head portion 572 h 3. In other embodiments, varying numbers of steppes may be present. - In use, the pair of
steppes 572 h 3a,3b serve to trap suture “S” (not shown) withinelongated head portion 572 h 3 to prevent/inhibit distal motion of the suture “S” (not shown) or withdrawal of suture “S” fromrecess 572 h. Suture “S” (not shown) is trapped along a path defined by the internal wall ofrecess 572 h andsteppes 572 h 3a,3b. If suture “S” (not shown) is provided with barbs on its outer surface,steppes 572 h 3a,3b may serve to engage the barbs on suture “S” (not shown) to further inhibit motion of sutures “S”. Thus,steppes 572 h 3a,3b work in conjunction withbarbs 572 h 1a to keep suture “S” (not shown) disposed in a substantially fixed position within theelongated head portion 572 h 3 during operation of theanvil assembly 520. - According to further embodiments of the present disclosure, it is contemplated that buttresses “B” may be provided or formed with integral wings or tabs extending therefrom for insertion and/or receipt into distal and/or proximal recesses of anvil assembly and/or cartridge assembly.

- Exemplary surgical buttresses “B” for use with the surgical stapling devices disclosed herein are shown and described in commonly assigned U.S. Pat. Nos. 5,542,594; 5,908,427; 5,964,774; and 6,045,560, and commonly assigned U.S. application Ser. No. 12/579,605, filed on Oct. 15, 2009 (now U.S. Patent Publication No. 2010/0092710, now U.S. Pat. No. 8,157,151), commonly assigned U.S. application Ser. No. 11/241,267, filed on Sep. 30, 2005 (U.S. Patent Publication No. 2006/0085034, now U.S. Pat. No. 7,938,307), and U.S. application Ser. No. 11/248,846, filed on Oct. 12, 2005 (U.S. Patent Publication No. 2006/0135992, now U.S. Pat. No. 7,823,592), the entire contents of each of which is incorporated herein by reference.
- Surgical buttresses “B” may be fabricated from a suitable biocompatible and bioabsorbable material. Surgical buttresses “B” may be fabricated from a non-absorbent material which does not retain fluid. Surgical buttresses “B” may be fabricated from “BIOSYN” made from GLYCOMER 631 (a block copolymer), a synthetic polyester composed of glycolide, dioxanone and trimethylene carbonate.
- One block of the resulting copolymer contains randomly combined units derived from p-dioxanone (1,4-dioxan-2-one) and trimethylene carbonate (1,3-dioxan-2-one). The second block of the copolymer contains randomly combined units derived from glycolide and p-dioxanone. The resulting polyester is an ABA triblock terpolymer possessing about 60% glycolide, about 14% dioxanone, and about 26% trimethylene carbonate.
- In accordance with the present disclosure, it is further contemplated that surgical buttresses “B” may be constructed and/or fabricated, from the above-identified materials, as a non-woven, absorbable felt and the like.
- With reference to
FIGS. 1-52 , and specifically,FIGS. 51 and 52 , as mentioned above, in accordance with the present disclosure, and either in place of or in addition to the methods and systems disclosed above for attaching surgical buttresses “B1, B2” to the tissue contacting/facing surface ofcartridge assembly 18 and/oranvil assembly 20 of a surgical stapling apparatus 100, surgical buttresses “B1, B2” may be further attached to the tissue contacting/facing surface ofcartridge assembly 18 and/oranvil assembly 20 ofsurgical stapling apparatus 10 in a number of different ways. - For example, a roughness of a tissue facing side of surgical buttresses “B1, B2” may be minimized, thereby reducing friction between tissues and the surgical buttresses “B1, B2” during tissue manipulation; a flexing of the surgical buttresses “B1, B2” between attachment points thereof may be minimized, thereby limiting movement where the surgical buttresses “B1, B2” is not fastened to
cartridge assembly 18 and/oranvil assembly 20; a shape of each surgical buttresses “B1, B2” may be modified to conform to the topography of tissue facing surface ofcartridge assembly 18 and/oranvil assembly 20; and/or increase a width of a profile of surgical buttresses “B1, B2” to be wider than a width of therespective cartridge assembly 18 and/oranvil assembly 20 widths so that some lateral shifting of surgical buttresses “B1, B2” can occur without compromising reinforcement of the entire staple line. - Specifically, the surface roughness of the material of surgical buttresses “B1, B2” may be minimized by any number of means including calendaring, applying heat and pressure, adding a lubricious coating, or forming the material on a flat surface. In the case of melt blown synthetic fabrics the material of surgical buttresses “B1, B2” could be produced by blowing fibers onto a smooth heated belt to encourage relaxation of the fibers to conform to the heated surface. Minimizing buttress roughness reduces the interaction of the material of surgical buttresses “B1, B2” when being moved across tissue, thus reducing forces exerted on the surgical buttresses “B1, B2” which lead to movement of surgical buttresses “B1, B2”.
- Also, flexing or the flexibility of the material of surgical buttresses “B1, B2” may be minimized by increasing the material density, basis weight, or choosing a base material that has a high Young's modulus. In the case of melt blown synthetic fabrics, this can also be accomplished by calendaring with heated rollers to increase intra fiber bonding and to increase fiber packing Less material flexing equates to the surgical buttresses “B1, B2” moving less when forces are exerted thereon during tissue manipulation.
- Additionally, as seen in
FIGS. 51 and 52 , a topography of the surgical buttresses “B1, B2” may be shaped through heat and pressure when on therespective cartridge assembly 18 and/oranvil assembly 20, or staple reload, so that the surgical buttresses “B1, B2” conforms to the shape of the tissue facing surface of therespective cartridge assembly 18 and/oranvil assembly 20. This concept could include deforming the topography of the surgical buttresses “B1, B2” through pressure with a patterned press in such a way that the material is slightly deformed locally into the staple retaining pockets in thecartridge assembly 18 and into the staple forming pockets on theanvil assembly 20 and also into the knife slots in theanvil assembly 20 andcartridge assembly 18. These local deformations would increase the contact area between the buttress and cartridge and anvil surfaces and would thus make it more difficult to displace the surgical buttresses “B1, B2” during tissue manipulation. - Further, with continued reference to
FIGS. 51 and 52 , a profile of the surgical buttresses “B1, B2” may be made wider so that its edges (lateral or otherwise) extend partially around the circumference and beyond a lateral side edge of therespective cartridge assembly 18 and/oranvil assembly 20, or staple reload. This could be done in combination with heat and pressure to ensure conformance of the material of the surgical buttresses “B1, B2” to the tissue facing surface of therespective cartridge assembly 18 and/oranvil assembly 20 so that shifting (i.e., lateral shifting) is hindered. Additionally, if any shifting were to occur the extra width of the profiles of the surgical buttresses “B1, B2” would help ensure that the entire staple line is reinforced with buttress. - In addition to the foregoing, the surgical buttresses “B” may be fabricated from any biodegradable and/or non-biodegradable material, including polymers, that can be used in surgical procedures. The term “biodegradable” as used herein is defined to include both bioabsorbable and bioresorbable materials. By biodegradable, it is meant that the material decomposes, or loses structural integrity under body conditions (e.g., enzymatic degradation or hydrolysis) or is broken down (physically or chemically) under physiologic conditions in the body, such that the degradation products are excretable or absorbable by the body. Absorbable materials are absorbed by biological tissues and disappear in vivo at the end of a given period, which can vary, for example, from hours to several months, depending on the chemical nature of the material. It should be understood that such materials include natural, synthetic, bioabsorbable, and/or certain non-absorbable materials, as well as combinations thereof.

Polymers formed therefrom include: polylactides; poly(lactic acid); polyglycolides; poly(glycolic acid); poly(trimethylene carbonate); poly(dioxanone); poly(hydroxybutyric acid); poly(hydroxyvaleric acid); poly(lactide-co-(ε-caprolactone-)); poly(glycolide-co-(ε-caprolactone)); polycarbonates; poly(pseudo amino acids); poly(amino acids); poly(hydroxyalkanoate)s such as polyhydroxybutyrate, polyhydroxyvalerate, poly(3-hydroxybutyrate-co-3-hydroxyvalerate), polyhydroxyoctanoate, and polyhydroxyhexanoate; polyalkylene oxalates; polyoxaesters; polyanhydrides; polyester anyhydrides; polyortho esters; and copolymers, block copolymers, homopolymers, blends, and combinations thereof.
- Synthetic degradable polymers also include hydrophilic vinyl polymers including phosphorylcholines such as 2-methacryloyloxyethyl phosphorylcholine, hydroxamates, vinyl furanones and their copolymers, and quaternary ammonia; as well as various alkylene oxide copolymers in combination with other polymers such as lactones, orthoesters, and hydroxybutyrates, for example.
- Rapidly bioerodible polymers, such as poly(lactide-co-glycolide)s, polyanhydrides, and polyorthoesters, which have carboxylic groups exposed on the external surface as the surface of the polymer erodes, may also be used.
