Abstract
Description
- This application claims the benefits of and priority to U.S. Provisional Patent Application Ser. No. 60/281,924 entitled: “MOLDED INSULATING HINGE FOR BIPOLAR INSTRUMENT” which was filed on Apr. 6, 2001 by Sartor et al., the entire contents of this application are hereby incorporated by reference herein.
- 1. Technical Field
- The present disclosure relates to joints and hinges which connect movable components of an electrosurgical instrument and methods for fabricating hinges for movable components of an electrosurgical instrument. More particularly, the present disclosure relates to an easily customizable hinge made from a plastic overmold composition which connects two end effectors for relative movement therebetween. The present disclosure also relates to a method for fabricating the overmolded hinge.
- 2. Background of Related Art
- Typically, joints and hinges for electrosurgical instruments which connect movable components are formed from an insulating material to prevent shorting between component parts and/or prevent the formation of alternate current paths through the instrument. As such, instrument designers have manufactured electrosurgical instruments which involve complex rotating hinge configurations to isolate, insulate and/or control the electrosurgically active areas of the instrument. For example, traditional metal hinge configurations typically include multiple independent subassemblies which are overmolded with plastic material having high bond strengths. These separately overmolded subassemblies are mechanically integrated and arranged in a series of manufacturing steps that often require tightly controlled and time consuming processes to achieve proper jaw alignment and reliable and consistent gap separation between electrodes. Moreover, additional steps are often undertaken to control other parameters associated with the rotational movement about the hinge, e.g., friction, torque, etc.
- Thus, a continuing need exists for a simple and effective insulating hinge that can be readily integrated into the manufacturing process to electrically isolate the movable components of an electrosurgical instrument. Further need exists for the development of a simplified manufacturing process which effectively fabricates an electrosurgical instrument which includes an insulated hinge that isolates and integrates the electrically active components of the instrument and results in the repeated formation of a reliable and easily customizable instrument which meets specific tolerance requirements for proper jaw alignment and gap distances.
- An electrosurgical instrument includes a pair of first and second elongated shafts each having an end effector attached to a distal end thereof and a handle. The handle is movable from a first position wherein the end effectors are disposed in spaced relation relative to one another to a second position wherein the end effectors are closer relative to one another. Each of the elongated shafts includes a hinge plate which mounts atop a pivot assembly for effecting movement of the end effectors relative to one another. The instrument also includes a hinge assembly which is overmolded to encapsulate and secure the hinge plates and the pivot assembly. The hinge assembly is made from an electrically insulating material which insulates the end effectors from one another.
- Preferably, the hinge assembly is made from a composition of materials selected from the group consisting of: polyamides, nylon, arcylanitride-butane nitro styrene acetyl, polyesters, syndiotactic-polystryrene (SPS), polybutylene terephthalate (PBT), polycarbonate (PC), acrylonitrile butadiene styrene (ABS), polyphthalamide (PPA), polymide, polyethylene perephthalate (PET), polyamide-imide (PAI), acrylic (PMMA), polystyrene-(PS and HIPS), polyether sulfone (PES), aliphatic polyketone, acetal (POM) copolymer, polyurethane (PU and TPU), nylon with polyphenylene-oxide dispersion and acrylonitrile styrene acrylate. In another embodiment, the hinge assembly is made from a composition of lubricating materials selected from the group consisting of: silicon, molybdenum disulfide and light olefins.
- In one embodiment, the pivot assembly includes a pivot pin integrally associated with a first of the hinge plates and a pivot hole formed within a second of the hinge plates. Preferably, the pivot pin is made from an electrically insulating material. In another embodiment, the overmold composition of the hinge assembly is disposed between the pivot pin and the pivot hole to electrically insulate each of the hinge plates from one another.
- In yet another embodiment, the hinge assembly includes a retention tab which secures the hinge assembly between the hinge plates. Preferably, the retention tab is formed during the overmold process as the overmold composition leaches through the pivot pin to form a tab on the outer-facing surface of the hinge plate. Once the retention tab cures, the hinge assembly is securely held between the hinge plates. In still yet another embodiment, the hinge assembly includes a stop member for limiting the movement of the end effectors relative to one another.
- The present disclosure also relates to a method of forming a hinge assembly and includes the steps of: providing a pair of first and second elongated shafts each having an end effector attached to a distal end thereof, a handle and a hinge plate. The handle is dimensioned to effect movement of the end effectors relative to one another. The method further includes the step of mounting the elongated shafts to a die block, introducing an overmold composition into the die block to encapsulate at least a portion of the hinge plates and curing the overmold composition to form the hinge assembly.
- In another embodiment, the method further includes the step of: selectively positioning at least one spacer between the end effectors to maintain a gap distance between the end effectors during the molding and curing step.
- Preferred embodiments of the presently disclosed surgical instrument having a molded insulating hinge assembly are described herein with reference to the drawings, wherein:

FIGS. 1-3C , one particular embodiment of anelectrosurgical instrument 10 includes twoelongated shafts distal end effector proximal handle portion Handles hinge assembly 20 from a first position wherein thedistal end effectors distal end effectors surgical instrument 10. - Each distal end, e.g., 32, has a
jaw member 36 disposed at the distal end thereof which includes atissue grasping surface 38 dimensioned to cooperate with the other jaw member, e.g., 66, and other tissue grasping surface, e.g., 68, to grasp tissue and other luminal structures upon actuation of thehandles jaw members hinge plate hinge assembly 20 as explained in more detail below. Hingeplate 35 includes apivot pin 74 which mechanically engages acorresponding pivot hole 61 disposed withinhinge plate 65 to formpivot assembly 70. -
Hinge assembly 20 as described herein relates to one particular embodiment for use with a bipolarelectrosurgical forceps 10, however, it is contemplated that the presently disclosedhinge assembly 20 could be dimensioned for use with other electrosurgical instruments including vessel sealing instruments, grasping instruments, ablation instruments, electrosurgical scissors, etc. Moreover, it is also envisioned that thehinge assembly 20 may be configured for use with a broad range of other non-electrical surgical instruments such as pliers, scissors, shears, crimpers and wire cutters. - Preferably, hinge
assembly 20 is made from acomposition 25 of insulating material such as plastic which is overmolded to encapsulate thehinge plates FIG. 2C ,pivot pin 74 includes a reinforcingportion 72 which allows themold composition 25 to extrude through thepivot pin 74 ofhinge plate 35 to anopposite side 63 ofhinge plate 65 to form aretention tab 50. More particularly, after a significant amount ofmold composition 25 is extruded around the reinforcingportion 72 of thepivot pin 74, theretention tab 50 is stamped against theopposite side 63 ofhinge plate 65 to secure thehinge plates pivot assembly 70. As can be appreciated in this embodiment of the present disclosure, themold composition 25 is contiguous with the exterior of thehinge plate 35 throughaperture 31, around reinforcingportion 72 and with theretention tab 50 which securely engages thehinge assembly 20 between thehinge plates - As can be appreciated, both the
mold composition 25 and theretention tab 50 are formed during the same molding step resulting in the formation of thehinge assembly 20. It is envisioned that once cured, theretention mechanism 50 forms a structural limit that at least partially controls the alignment of thedistal end effectors jaw members retention tab 50 may be made from the same or adifferent mold composition 25 and is designed to mechanically engage thepivot pin 74 or thehinge plate 65 to secure the hinge assembly between thehinge plates - As best shown in the exploded view of
FIG. 4 , the formation of thehinge assembly 20 in this manner electrically isolates the twoend effectors jaw members outer periphery 75 ofpivot pin 74 which electrically isolateshinge plate 35 fromhinge plate 65. As can be appreciated, theretention tab 50 which, as mentioned above, is also formed of plastic which extrudes throughpivot pin 74 to theopposite side 63 ofhinge plate 65, not only retains the twohinge plates pivot assembly 70 but also electrically isolates thehinge plates - Because the presently disclosed
hinge assembly 20 is preferably formed during a single manufacturing step, it can be easily customized and dimensioned to suit a particular purpose or to achieve a particular result. For example, the alignment of thejaw members jaw members hinge assembly 20 may be molded or formed during the manufacturing process such that thejaw members FIG. 5 . - Generally, hinge 20 is formed from an overmold composition containing a joint-forming base resin material and a lubricating component. Hinge-forming materials for use herein can be any commercially available materials known to one skilled in the art for toughness and strength as well as being capable of injection molding. Suitable joint-forming base resin materials include, but are not limited to, polyamides such as nylon, arcylanitride-butane nitro styrene; acetyl, polyesters, etc. Preferably, the overmold composition is made from a plastic or plastic-based material having a Comparative Tracking Index of about 300 volts to about 600 volts for dielectric isolation. For example, the
overmold composition 25 may be made from a group of materials selected from a group which includes Nylons, Syndiotactic-polystryrene (SPS), Polybutylene Terephthalate (PBT), Polycarbonate (PC), Acrylonitrile Butadiene Styrene (ABS), Polyphthalamide (PPA), Polymide, Polyethylene Terephthalate (PET), Polyamide-imide (PAI), Acrylic (PMMA), Polystyrene (PS and HIPS), Polyether Sulfone (PES), Aliphatic Polyketone, Acetal (POM) Copolymer, Polyurethane (PU and TPU), Nylon with Polyphenylene-oxide dispersion and Acrylonitrile Styrene Acrylate. Alternatively, it is envisioned that a non-plastic insulating material, e.g., ceramic, may be used in lieu of or in combination with one or more of the above-identified materials to facilitate the manufacturing process and possibly contribute to more uniform and consistent transfer of electrosurgical energy across the tissue. - Suitable lubricating components for use with the base resin material include a broad range of materials known to compliment the overmold composition to provide mold having a low bonding strength with good surface lubricating qualities. Such lubricating components include, but are not limited to, silicon-like materials, molybdenum disulfide, light olefins, etc. Depending upon the overall composition of the base resin material being used, a lubricating component may not be required.
- It is also anticipated that additional materials may be employed in combination with the above materials to achieve suitable levels of toughness and strength in the molded
hinge 20. These additional materials may include, for example, reinforcing agents such as glass fibers, ground glass, or elongated glass fibers. For example, in one particular embodiment, hingeassembly 20 is formed from a commercially available nylon material having about 2.5 wt. % glass fiber reinforcing material and a silicone lubricating component in the range of about 0.75 wt. % to about 10 wt. %. In another embodiment, hingeassembly 20 may be formed from a nylon having glass fiber reinforcing material in the range of about 5 wt. % to about 40 wt. % and silicone in the range of about 2 wt. % to about 8 wt. %. - While silicone or other lubricating agents are typically used in injection molding processes, it has been found that the amount of silicone should be tightly controlled to provide uniform and consistent curing and operating efficiencies. It is envisioned that the silicone component of the overmold composition creates a sustained lubricated surface at the interface between
hinge plates hinge assembly 20, produces an overmold composition having a low bond strength. As can be appreciate, although theovermold composition 25 has a low bond strength to the surrounding metals, i.e.,elongated shafts plates retention tab 50 andaperture 31. - As mentioned above, the presently disclosed
hinge assembly 20 may be formed during a single manufacturing step and may be easily customized depending upon a particular purpose or to achieve a particular result. For example, parameters such as self lubrication of thehinge assembly 20,hinge assembly 20 strength,jaw member jaw members jaw members 36 ad 66 (or electrodes or probes attached to thejaw members 36 and 66) may be easily achieved. - The present application is not limited to the above identified materials, but contemplates a broad range of
overmold composition 25 in varying combinations and amounts that provide an overmold composition suitable for the function ofhinge assembly 20. It is envisioned that applications described herein relating to the injection overmolding of thermoplastic polyamides, for example, may be translated into other areas including, but not limited to, other engineering plastic materials, engineering metals and ceramics that may be selectively applied in varying insulative as well as mechanical applications. - The
overmold composition 25 of the present disclosure is configured to create a tough andstrong hinge assembly 20 by at least partially encapsulating thehinge plates overmold composition 25 provides suitable strength as a result of its continuity of encapsulation as well as the ability of theovermold composition 25 to form surface features which are specifically dimensioned to improve the strength of thehinge assembly 20 once cured. For example, features within thepivot pin 74 and features within thepivot hole 61 may be provided to increase the overall strength of the instrument and/or hingeassembly 20, e.g. notches, detents, cavities, overmolded posts, etc. Further, structural strength for thehinge assembly 20 may be gained by coating or filling features defined in the surface of thehinge plates hinge plates hinge assembly 20 to thehinge plates 35. - Preferably, the
elongated shafts elongated shafts end effectors hinge plates overmold hinge assembly 20 as presently disclosed herein greatly simplifies the overall manufacturing and assembly processes. -
Instrument 10 may also include surface treatments (e.g., nylon powder coatings, chemical treatments, nickel alloy coatings, mechanical finish treatments, shrink tubing, etc.) which facilitate manipulation of the tissue structures, enhance conduction of electrosurgical energy across thejaw members - Preferably, the thickness of the
hinge assembly 20 can be selectively altered depending upon a particular purpose or for use with a certain instrument. The ultimate thickness and strength of theovermold composition 25 is also related to the viscosity of theovermold composition 25 and the duration and temperature of the curing process. For example, thehinge assembly 20 may include a range of thickness from about 0.020 to about 0.040 inches in thickness. The thickness of theovermold composition 25 also depends on mechanical load bearing and dimensional requirements of a particular application. - As best shown in
FIG. 4 , theouter periphery 75 ofpivot pin 74 provides a basis for the formation of additional molded material around thepivot pin 74 which not only electrically insulates thejaw members instrument 10. - It is envisioned that the hinge assembly may be designed as a more complex mechanism and/or may be designed to encapsulate a more complex pivoting mechanism. For example, it is contemplated that the
hinge assembly 20 may include various multiple-link systems such as a two-bar, three-bar or four-bar linkage or may include a two-step hinge. Thepivot pin 74 and/or thepivot hole 61 may also be dimensioned in a variety of different shapes and sizes depending upon a particular purpose or to achieve a particular result, e.g., cam and cam-follower, arcuate, elliptical, etc. It is also envisioned that thehinge assembly 20 may include one ormore stop members 19 which limit the overall distance that thejaw members jaw members - In one embodiment,
retention tab 50 may be configured to mechanically engage a portion of thehinge plate 65 and/orpivot pin 74 which is contemplated to serve two purposes: 1) to mechanically retain theretention tab 50 against thehinge plate 65 and further secure theinstrument 10 as assembled; and 2) to bias thepivot assembly 70 to a predetermined open, closed, or intermediary position. For example, the outer-facingsurface 63 ofhinge plate 65 may be provided with slots or grooves (not shown) which mechanically engage theretention tab 50. - With respect the to particular surgical instrument of
FIGS. 1-4 , i.e.,bipolar forceps 10, first and secondconductive wires distal end effector FIG. 2A ) connects thefirst jaw member 36 to a first electrical potential and the second electrical conductor 45 (seeFIG. 3A ) connects thesecond jaw member 66 to a second electrical potential. Preferably, the first and secondelectrical conductors elongated shafts electrical conductors respective jaw members jaw members conductive jaw members hinge assembly 20 includes at least onestop 19 which abuts againstelongated shafts jaw members - Preferably, hinge
assembly 20 is manufactured in a single injection molding or manufacturing process step in which elongatedshafts overmold composition 25 of thehinge assembly 20 is then injected between thejaw members hinge plates pivot assembly 70. As mentioned above, thehinge assembly 20 is strengthened by the continuity of theplastic overmold composition 25 which extrudes through thepivot pin 74 andpivot hole 61 to form theretention tab 50. Thus, in one particular embodiment, thehinge assembly 20 is completely formed by overmold composition flowing around and through the various components parts of thehinge assembly 20 and thepivot assembly 70. As mentioned above, the retention tab may be a separate component made from the same or a similar composition which is dimensioned to mechanically engage thepivot pin 74 or the outer-facingsurface 63 of thehinge plate 65. - As mentioned briefly above and as shown in
FIG. 5 , aspacer 100 may be positioned betweenjaw members spacer 100 sets a fixed gap distance “G” betweenjaw members jaw members stop 19 during the overmolding process. As can be appreciated, different and/or customized gap distances “G” between thejaw members - The presently disclosed overmolding process also enables the manufacturer to customize the precise alignment of the
jaw members jaw members hinge assembly 20,pivot assembly 70 andjaw members - From the foregoing and with reference to the various figure drawings, those skilled in the art will appreciate that certain modifications can also be made to the present disclosure without departing from the scope of the present disclosure. For example, it is contemplated that
hinge assembly 20 can be configured to join a plurality of different components or subassemblies in the assembly depending upon a particular purpose. Moreover, theouter periphery 75 ofpivot pin 74 could also include features such as a series of undulations or knurling, or a series of radially aligned cavities having features within those cavities that strengthen the mechanical interface of the overmold composition to the pivotingassembly 70. - In one embodiment, the instrument includes a conductive strip (not shown) disposed through one shaft, e.g.,
shaft 30. Electrosurgical wires or cables (not shown) from an electrosurgical generator (not shown) connect the two electrical potentials to the conductive strip. The opposite end of the conductive strip includes one electrical connection to endeffector 32 and a second electrical connection to pivotassembly 70 which provides electrical continuity to theopposite end effector 62. More particularly, the second electrical connection of the conductive strip makes contact across the moving junction of the pivot assembly. It is not necessary that the conductive strip wrap around thepivot pin 74 between the instrument halves because during the molding process the conductive strip is forced into intimate contact with theopposite end effector 62, i.e, the flow of the uncured hinge material positions the conductive strip into contact withend effector 62. - As a result thereof, secondary washers or force loading devices are not required to initiate contact between the conductive strip and the
opposite end effector 62. The conductive strip my also include a series of wave-like folds, e.g., accordion folds, which give the conductive strip a spring-like quality and which fosters contact with theopposite end effector 62 during and after curing. As can be appreciated, this arrangement assures that a moving or sliding contact is maintained between the conductive strip and theend effector 62 during movement, i.e., pivoting, of the end effectors relative to one another. - While several embodiments of the disclosure have been shown in the drawings, it is not intended that the disclosure be limited thereto, as it is intended that the disclosure be as broad in scope as the art will allow and that the specification be read likewise. Therefore, the above description should not be construed as limiting, but merely as exemplications of preferred embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
