DETAILED DESCRIPTION

[0057] Embodiments of the present disclosure may provide a dual end bellow prosthesis insertion device wherein each end may be trimmed as needed to accommodate breast implants that may be the same size or may be different sizes. It should be appreciated that the ends may have the same size opening in some embodiments of the present disclosure, but there may be other embodiments where one end is larger than the other end. There may be side flaps through which the implants may be inserted in the bellow, and these side flaps may be in the middle so that each implant may be placed in the bellow through a single opening, although only one implant may be loaded at a time. The implant may be inserted into the breast pocket, and the bellow may be turned around so that the second implant may be loaded into the bellow and inserted into the breast pocket through a second, unused end of the bellow. This may keep skin bacteria from being transferred from one implant pocket skin edge to the second implant pocket, which can occur if the two implants are inserted into the implant pockets using the same implant insertion device opening.

[0058] Referring now to FIG. 1, the top side perspective view of bellow 40 is manufactured with a sheet material such as plastic or a flexible, surgical-grade nylon. The plastic may be strengthened or reinforced with fibers. Bellow 40 may be clear, or semi-transparent, to allow observation of prosthesis 30 moving from bellow 40 into patient pocket 24.

[0059] Bellow 40 may have three openings: first insertion end 42 for inserting a range of implant sizes into incision 20; second insertion end 44 for insertion of a range of implant sizes into incision 20; and prosthesis opening 54, surrounded by exterior tab 50 and internal tab 52, for inserting prosthesis 30 into bellow 40. Each end 42, 44 may be considered an implant insertion end because bellow 40 is rotated during surgery so that each end 42, 44 is sequentially inserted in incision 20. FIG. 1 shows tabs 50, 52 located central to ends 42 and 44 and internal tab 52 pushed through prosthesis opening 54 to prevent the implant from passing to the outside of bellow 40, and exterior tab 50 folded over prosthesis opening 54. Exterior tab 50 may be folded and held in place by a surgeon's hands, friction or attached by glue, adhesive, heat bond, surgical tape or other coupling mechanism. While FIG. 1 shows both tabs 50, 52 folded into the working position, bellow exterior tab 50 and bellow internal tab 52 may initially be presented to the surgeon with both tabs 50, 52 outside of bellow 40 and surrounding prosthesis opening 54. While the preferred embodiment shows different sized tabs 50, 52 to distinguish exterior tab 50 from internal tab 52, tabs 50, 52 may be of the same size in embodiments of the present disclosure.

[0060] Bellow 40 may be assembled using seal tucks 56 which comprise two (2) tab-side seal tucks 57, and one (1) abutted-side seal tuck 58. In a preferred embodiment, the assembly may be done prior to packaging and shipping to the surgeon. In an alternate embodiment, seal tucks 56 may be sealed to base fold 46 by the patient's operating team. See FIG. 4B for additional illustration of the assembly using seal tucks 56.

[0061] Bellow 40 prevents breast implant 30 from touching the patient's skin tissue 28, prevents only one insertion end 42 or 44 from being used in both (right and left breast) incisions 20, and prevents damage to implant 30 during implant insertion. Bellow 40 may be manufactured to accommodate any breast implant 30 shape, volume, and diameter. Each insertion end 42, 44 may be trimmed by the surgeon to allow insertion of a range of implant 30 sizes. The manufacturer may also require or suggest two specific skin incision 20 lengths to allow insertion of the implant through bellow 40 into incision 20. The specifications take the burden off the surgeon to try to make shorter incisions 20.

[0062] FIG. 2 shows a bottom view of the manufactured version of bellow 40 once bellow fold 48 is folded over base fold 46 along the abutted seam and three seal tucks 56 are adhered to base fold 46. Bellow 40 comprises initial fold 48 partially sealed on the periphery to base fold 46 so that it leaves implant insertion ends 42, 44, bellow prosthesis opening 54, bellow exterior tab 50 and bellow internal tab 52.

[0063] Turning to FIG. 3, the illustration depicting a perspective view of unassembled bellow 40. Bellow 40 comprises two simple, convex, irregular hexagons folds 46, 48 with opposing prosthesis insertion tabs 50, 52. In a preferred embodiment, tabs 50, 52 are located centrally and opposing the abutted sides of manufactured bellow 40. In a preferred embodiment, as shown in FIGS. 3-4D, base fold 46 is manufactured abutted against initial fold 48 along either edge opposing the tabbed side of folds 46, 48. In a second embodiment, initial fold 48 and base fold 46 would be separately manufactured and assembled together at a later stage.

[0064] In the preferred embodiment, bellow 40 would be folded along an abutted edge and manufactured with three seal tucks 56 along: (a) initial fold 48 abutted-side edge from the abutment to second insertion end 44; (b) initial fold 48 tab-side edge from exterior tab 50 to first insertion end 42; and (c) initial fold 48 tab-side edge from exterior tab 50 to second insertion end 44.

[0065] In the second embodiment, bellow 40 would be manufactured with separated initial fold 48 and base fold 46, stacked over each other and assembled with four seal tucks 56 along: (a) initial fold 48 abutted-side edge from the abutment to first insertion end 42; (b) initial fold 48 abutted-side edge from the abutment to second insertion end 44; (c) initial fold 48 tab-side edge from exterior tab 50 to first insertion end 42; and (d) initial fold 48 tab-side edge from exterior tab 50 to second insertion end 44.

[0066] Bellow seal tucks 56 may be folded over opposing fold 46, 48 and attached by glue, adhesive, heat bond, surgical tape or other coupling mechanism.

[0067] In another embodiment, seal tucks 56 may be replaced with a simple seam along the edges to bind initial fold 48 and base fold 46 with glue, adhesive, heat bond, surgical tape or other coupling mechanism.

[0068] FIGS. 4A to 4D show the assembly of bellow 40. In FIG. 4A, the pattern is folded along the abutted edge so that base fold 48 and initial fold 46 are stacked over each other with tabs 50, 52 pointing in the same direction.

[0069] Then in FIG. 4B, seal tucks 56 are folded over opposing fold 46, 48 and sealed to opposing fold 46, 48 with any desired manufacturing sealing technique.

[0070] With breast implant 30 in place inside bellow 40, FIG. 4C, internal tab 52 is pushed through prosthesis opening 54. Internal tab 52 prevents implant 30 from inadvertently ejecting through prosthesis opening 54 during the operation.

[0071] In FIG. 4D, with the internal tab 52 inside prosthesis opening 54, exterior tab 50 may be pushed over the top surface of opposing fold 46, 48. Exterior tab 50 may be secured to opposing fold 46, 48 with the surgeon's hands, surgical tape, heat seal, instant glue, or other forms of seals. Adhered seal 50 opposes prosthesis opening 54 and joins initial fold 48 and base fold 46.

[0072] As illustrated in FIG. 5, in the preferred embodiment, a coating of surgical lubricant 60 may be used on implant 30 and the inner surface of bellow 40. As an alternative, bellow 40 may be provided with a coating that becomes slick when wet. In still another alterative, prosthesis 30 may be provided with a slick surface, such as surgical lubricant 80. The surgeon also has the option of applying lubricant 60 to prosthesis 30 directly before inserting into bellow 40. Lubricant 60 may also act as an antibiotic solution.

[0073] After lubrication, breast implant 30 is inserted into bellow 40 by the surgeon and nurse. To do so, the nurse opens bellow prosthesis opening 54 by separating tabs 50, 52, and the surgeon slides prosthesis 30 through bellow prosthesis opening 54. The surgeon would then fold internal tab 52 into bellow prosthesis opening 54 to prevent breast implant 30 from moving back out of opening 54. Exterior tab 50 may be left extended or folded over opposing fold 46, 48. If desired, exterior tab 50 may be sealed to opposing fold 46, 48. In a preferred embodiment, inserting prosthesis 30 into bellow 40 would be completed prior to inserting retractor 70 into patient incision 20. However, a surgeon could perform this step while bellow 40 is inserted in incision 20. In a preferred embodiment, the surgeon would insert one prosthesis 30 into bellow 40 at a time.

[0074] In FIG. 6, the surgical team inserts lubricant 60 in opposing end 42, 44 of end 42, 44 inserted in incision 20. Liquid lubricant 60 surrounds breast implant 30 inside bellow 40. An antibiotic solution may be used as lubricant 60.

[0075] FIG. 7A shows patient 10 positioned in a supine position prior to incision 20 being made in the patient's skin tissue 28. In the figure, incision 20 is cut in left-side inferior breast 22 crease. With incision 20 opened, the surgeon then forms pocket 24 in one of two places under breast 22: subglandular (between breast 22 tissue and pectoralis major muscle) or subpectoral (deep to the pectoralis major muscle). Pocket 24 is sized to match prosthesis 30. By manipulating retractor handle 72, retractor handle proximal end 74 and retractor proximal lip 76 are inserted into incision 20 to both retract incision 20 and hold incision 20 open.

[0076] Retractor 70 assembly comprises handle 72 located in the center, retractor handle proximal end 74, and retractor handle proximal end lip 76. Retractor 70 may have various shapes and sizes to match the application or surgeon preferences. Handle 72 of retractor 70 is bent or angled on the ends relative to the intermediate portion. Proximal end 74 of retractor 70 has lip 76 that is angled relative to end 74. Retractor 70 is made of metal, such as stainless steel, but may also be manufactured in a surgical plastic in other embodiments of the present disclosure.

[0077] Retractor proximal end 74 is structured and arranged to be inserted through incision 20 into pocket 24 of patient 10. Proximal end lip 76 helps maintain proximal end 74 of retractor 70 beneath skin tissue 28 of patient 10.

[0078] Retractor 70 extends laterally from bellow 40, so as not to interfere with the surgeon manipulating bellow 40, with the proximal ends of retractor 74 and proximal end lip 76 inserted into incision 20 and located under skin tissue 28 and moved to retract incision 20. Implant insertion ends 42, 44 of bellow 40 may be lubricated with lubricant 60 and inserted into open incision 20.

[0079] Bellow 40, distal to incision 20, is squeezed and/or twisted to force prosthesis 30 toward insertion end 42, 44 of bellow 40 and into pocket 24. Prosthesis 30 deforms to fit through second insertion end 44.

[0080] Once prosthesis 30 is located inside pocket 24, retractor 70 is removed from incision 20, followed by bellow 40. Incision 20 is then closed.

[0081] Finally, in FIG. 7B, showing a right-side of a patient, retractor 70 is inserted in second breast 22 incision 20 and moved to retract incision 20. Bellow 40 is then rotated so that the second unused implant insertion end 42 or 44 is introduced to incision 20 of second breast 22. The other implant insertion end 42 or 44 may be lubricated with lubricant 60 and inserted into open incision 20.

[0082] Bellow 40 is squeezed and/or twisted to force prosthesis 30 toward insertion end 42, 44 of bellow 40 and into pocket 24. Prosthesis 30 deforms to fit through insertion end 42,44.

[0083] Once prosthesis 30 is located inside pocket 24, retractor 70 is removed from second incision 20, followed by bellow 40. Second incision 20 is then closed.

[0084] If bellow 40 is designed for reuse, it is subjected to sterilization procedures. If bellow 40 is designed for single use, it is disposed of One embodiment of bellow 40 and method is that implant insertion ends 42, 44 may be properly sized during manufacture with respect to each other so that smallest breast implants 30 will fit through first insertion end 42 and the larger range of implants 30 may be inserted through second insertion end 44. This allows the proper pressure to be applied to each range of implants 30 as they deform through insertion ends 42, 44.

[0085] Implant 30 is subject to damage if implant 30 is mishandled. Possible mishandling includes subjecting implant 30 to undue stresses or pressures, such as may be caused by attempting to squeeze implant 30 through implant insertion end 42, 44 that is too small, and folding of the external silastic shell, internal fracture of the cohesive silicone gel. A surgeon may make incision 20 in patient 10 that is too short for implant 30 and thus too much force is required to squeeze implant 30 into pocket 24. With bellow 40, implant 30 is protected from damage by the provision an adequate skin incision length and of the properly sized second insertion end 44. The major complication with implants 30 is capsular contracture thought to be due to sub-clinical infection. Sub-clinical infection is most likely caused by pushing implant 30 through skin incision 20, dragging natural skin 28 bacteria (still present after proper skin 28 preparations) into pocket 24 surgically created for implant 30. Use of bellow 40 prevents implant 30 from coming in contact with skin tissue 28 during the insertion process.
