Definitions
- the present invention relates to health care devices comprising medical and veterinary devices, and more particularly to devices useful in suturing or closing wounds or incisions.
- Surgical skin stapling has been found to be desirable in that it requires less skill of the health care clinician than conventional suture ligature.
- removal of staples is faster and easier than suture ligature.
- simplicity in wound and incision closure decreases the possibility of error, an accomplishment of particular importance in the health care field.
- Surgical stapling also provides better post-surgery aesthetic appearance than does conventional suture ligature and needle wound closure. Further still, postoperative infection is reduced in the use of skin stapling over suture ligature.
- surgical stapling takes less time than conventional suture ligature
- surgical stapling is economically advantageous. Both implanting and removing surgical staples is easier than placing and removing conventional sutures. It is, for example, estimated that the typical surgical stapling operation takes approximately 10% of the time of a conventional ligature placement. Thus, a significant time savings is involved in using surgical staples for wound and incision closure.
- Current surgical staple devices generally provide a feeder shoe to urge a plurality of staples toward the staple-forming or exiting end of the stapling device.
- a limitation in such feeder shoes and urging mechanisms is that staples are allowed to jam on the sliding surface as the staples move toward the staple-forming or exiting end of the stapling device.
- Such staple jams can be at least inconvenient to clinicians who temporarily cannot utilize the stapling device.
- a limitation in the feeder shoes and urging mechanisms which can lead to staple jams is that while all such feeder shoes contact at least a part of one of the staples, and some feeder shoes contact much of one side of a staple, when a staple slips, the staple can be lodged in spaces either between the staple stack containing a plurality of staples and the track upon which the plurality of staples slide, within other spaces existing within the feeder shoe itself, or between the feeder shoe and the track upon which the staple stack slides.
- a staple housing such as a staple cartridge
- the outer surfaces of a feeder shoe are continuous with the staple housing and in which the feeder shoe acts as a traveling blocking surface against a fixed blocking surface.
- Another limitation of current feeder shoes is that. if such feeder shoes are extended completely to the end of the staple cartridge, as when all staples in the staple cartridge have been used so that no staples remain in the staple cartridge, forcing the staple former on the feeder shoe can damage these parts. It is therefore desirable to avoid this force on the feeder shoe and staple former.
- a limitation of current surgical stapling devices is that staples are implanted substantially orthogonal to the skin surface.
- By inserting staples at an angle of between about 10° - 45° relative to the skin surface and then tilting the staple so that the staple is ultimately positioned substantially orthogonal to the skin surface greater resulting anastomosis can be obtained as the skin grows together. This greater anastomosis allows for shorter healing time.
- a surgical stapling device has a body member having a staple cartridge recess, a trigger member movably positioned with the body member, a staple former positioned with the body member movably positioned with the trigger member, a staple cartridge having a staple, the staple cartridge removably positioned with the staple cartridge recess and an anvil member positioned with the body member for transforming the staple from a pre-implantation configuration to a post-implantation configuration upon movement of the trigger member from an at-rest position to a staple-forming position.
- the preferred embodiment also includes a body member having an aligning surface for implantation of the staple at an insertion angle relative to the skin surface of between about 10° and about 45°.
- the surgical staple cartridge includes a housing member having a staple-forming end, a plurality of staples having a lead staple movably positioned in the housing member and a first opening in the staple-forming end of the housing member to allow access to the lead staple and a second opening in the staple-forming end of the housing member to allow the lead staple to move therethrough.
- the staple cartridge preferably contains a feeder shoe for urging the plurality of staples toward the staple-forming end of the housing member.
- the staple cartridge also preferably contains a fixed blocking surface on the housing member and a traveling blocking surface on the feeder shoe. The traveling blocking surface is sized so that the feeder shoe moves along the fixed blocking surface of the housing member while blocking the staple.
- the staple cartridge also preferably includes a flexible arm extending from the housing member and moving between a memory position and a flexed position outwardly from the memory position for a snap fit of the staple cartridge to the stapling device. Additionally, the feeder shoe is angled to prevent damage to the staple former and feeder shoe when the trigger member is squeezed when no staples remain in the staple cartridge.

- angled surfaces assist in guiding prongs 44C and 44D of staple former 44 to lead staple 64.
- a second opening 50G in the staple-forming end of housing member 50 is also aligned vertically with lead staple 64, as shown in Figs. 6 and 7, as well as Figs. 17-19.
- This second opening 50G is created by the ending of the bottom wall 66, as shown in Fig. 7.
- the second opening 50G allows lead staple 64 to move through the second opening 50G and strike anvil tab 40A upon the lead staple 64 being struck by staple former 44.
- staple cartridge housing member 50 comprises staple feeder ramps 68 and 70 within housing member 50.
- the staple stack 72 containing a plurality of staples in a pre-implantation configuration rests upon staple feeder ramps 68 and 70, and slides toward the front or staple-forming end of the staple cartridge 16 upon the staple feeder ramps 68 and 70 when urged by the feeder shoe 74.
- feeder shoe 74 comprises feeder ramp grooves 76 and 78, through which staple feeder ramps 68 and 70 (see Fig. 8), respectively, insert, allowing feeder shoe 74 to slidably travel along staple feeder ramps 68 and 70 toward the front of staple cartridge 16.
- FIG. 8 staple feeder ramp grooves 76 and 78
- feeder shoe 74 also comprises a groove 80.
- This groove 80 fits onto track 50H of the housing member 50, allowing the feeder shoe 74 to slidably travel along the upper surface of track 50H toward the front of staple cartridge 16 with guiding blocks 82 and 84 of feeder shoe 74 sliding along guiding block grooves 86 and 88 of housing member 50, respectively.
- the anvil member 40 rests against the bottom side of track 5 OH comprising groove 501, as shown in Fig. 15.
- feeder shoe 74 when feeder shoe 74 is slidably inserted into housing member 50, the feeder shoe 74 is fully configured with the housing member 50 such that both right and left sides 74A and 74B, respectively, as well as top and bottom sides 74C and 74D, respectively, are in continuity with all inside surfaces of housing member 50, so that staple feeder ramps 68 and 70, track 50H, frontal tabs 50J and 50K and the remaining inside surface of housing member 50 constitute a fixed blocking surface while feeder ramp grooves 76 and 78, guiding blocks 82 and 84, as well as the remaining outer surface of feeder shoe 74, including sides 74A, 74B, 74C and 74D constitute a traveling blocking surface.
- Feeder shoe 74 additionally comprises a feeder rod 92.
- a spring 90 is positioned with feeder rod 92 that is received in pusher rod 58, as best shown in Figs. 7, 8 and 15.
- cap tabs 94 and 95 fit within cap tab inserts 96 and 97, as seen in Figs. 15, 18 and 19.
- spring 90 exerts a force against feeder shoe 74, biasing the feeder shoe 74 toward the front or staple-forming end of staple cartridge 16.
- the feeder shoe 74 moves toward the front or staple-forming end of housing member 50, thus moving the staple stack 72 containing a plurality of staples toward the front or staple- forming end as well.
- Feeder shoe 74 additionally comprises angles 74E and 74F. As best shown in Fig. 16, the angles 74E and 74F each comprise a surface slanted away from vertical toward the pusher rod 58 at an angle of about 45°. The angles 74E and 74F move the feeder shoe 74 rearward toward the pusher rod 58 (toward the staple feeding or rear end) when the prongs 44C and 44D of the staple former 44 (see Fig. 9) strike the angles 74E and 74F, such as when there are no more staples in staple cartridge 16. Such movement prevents damage to the edges of the prongs 44C and 44D (see Fig. 9) of the staple former 44 when the trigger member 12 is squeezed when no staples remain in the staple cartridge 16. Fig.
- FIG. 18 shows a staple cartridge 16 with no staples therein, with feeder shoe 74 engaged with frontal tabs 50J and 50K of housing member 50.
- Fig. 15 best illustrates the frontal tabs 50J and 5 OK.
- Fig. 19 shows feeder shoe 74 moving rearward towards pusher rod 58 in response to a downward strike by staple former 44 when no staples remain in the staple cartridge 16.
- staples are inserted into the skin surface at an insertion angle of about 10° from vertical, as best shown in Fig. 21.
- the upper surface 40B of anvil tab 40A is angled upward relative to the rest of the tab 40A. This provides frictional force sufficient to rotate the implanted staple towards vertical when the stapling device is moved rearwardly in the normal course of inserting multiple staples.
- the force of compressed skin pressing against the legs of the staple exceeds the frictional force exerted by the upper surface 40B of tab 40A on the crown of the staple, and the anvil 40 slides out from underneath the crown portion 100 of the staple.
- the staple is brought to an angle near vertical as shown in Fig.
- a crowning space 98 as shown in Fig. 11, is minimized.
- Fig. 11 represents an implanted staple before the staple has been brought to near vertical
- Fig. 12 represents an implanted staple after the staple has been brought to near vertical.
- the crowning space 98 is smaller after the staple is rotated. Minimizing the crowning space minimizes the possibility that the crown portion 100 of the staple could be caught on an object which would create trauma to the wound site so that healing time is potentially decreased.
- the stapling device of the present invention comes to the clinician in assembled, loaded and sterilized form. Grasping the device in his or her right or left hand by rearward handle portion IOC and with his or her fingers about trigger member 12 as shown in Fig. 1, the clinician locates the instrument over the wound or incision to be sutured. This is illustrated in Figs. 9-12 wherein a patient's skin surface 104 is shown containing a wound or incision 106, Fig. 10.
- the clinician squeezes trigger member 12 against the action of leaf spring member 48 as shown in Figs. 1 and 2.
- pivoting of trigger member 12 in a counterclockwise direction will cause the nose portion 12B of trigger member 12 to shift staple former 44 to its second extended or staple-forming position.
- staple former 44 shifts downwardly, its lowermost edges 44G and 44H, Figs. 9-11, will contact the crown portion 100 of lead staple 64 to either side of tab 40A of anvil member 40.
- the staple former 44 moves further downward, the curved portions 44E and 44F of prongs 44C and 44D will initiate bending of the crown portion 100 of the lead staple 64.
- Bending may be assisted by tooling marks 108 and 110. This, in turn, will cause staple legs 112 and 114 to enter and be implanted in the skin surface 104, Figs. 10-11. At the completion of the forming and implanting procedure, the staple will have the configuration shown in Fig. 11, closing incision 106, Fig. 10. It is contemplated to include in an embodiment of the invention a pre-cock position at which point a detent engages and prevents return of the trigger member as described in U.S. Patent No. 4,669,647 issued to Storace, relevant portions of which relating to a pre-cock position are incorporated herein by reference.
- leaf spring member 48 will return the trigger member to its normal position as shown in Fig. 1. This, in turn, will cause staple former 44 to return to its first retracted or at-rest position. In the meantime, spring 90 and feeder shoe 74 (see Figs. 15, 18 and 19) will advance the next forwardmost staple of staple stack 72 against the tabs 50 J and 50K. As best shown in Figs. 7 and 17, tabs 50J and 50K align lead staple 64 with first openings 50C and 50D. Modifications may be made in the invention without departing from the spirit of it. For example, leaf spring member 48 can be replaced by a compression spring or any other appropriate type of biasing means.
