Forceps for performing endoscopic or arthroscopic surgery
First Claim
1. A body assembly (42) of surgical forceps (40) for retaining an adapter (58) of a tube assembly (46) having a plurality of locking grooves (62) defined circularly around the tube assembly (46), said body assembly (42) comprising;
- a housing (134) having an axial bore (140) with a circular cross section,said housing (134) including a top surface (96) with said top surface (96) defining a transverse bore (148) extending along a locking axis (BB) and opening to said axial bore (140),said housing (134) defining a lateral bore (160) extending along a plunger axis (AA) with said lateral bore (160) intersecting said transverse bore (148),a lock (150) disposed in said transverse bore (148) and including a locking contact (156), and a locking pin (154) spaced axially from said locking contact (156), said locking pin (154) engagable with one of the locking grooves (62), anda plunger (166) including a plunger shaft (168) with said plunger shaft (168) disposed in said lateral bore (160) and intersecting said transverse bore (148),said plunger shaft (168) including a plunger ramp (174) sloping relative to said plunger axis (AA) and slidably interfacing with said locking contact (156) of said lock (150), wherein said plunger shaft (168) imparts a force on said locking contact (156) when said plunger (166) is pushed along said plunger axis (AA) to thereby move said locking pin (154) along said locking axis (BB) and disengage said locking pin (154) from the locking groove (62) and allow the tube assembly (46) to be rotated within the axial bore (140), andsaid plunger shaft (168) defining a slot (177) wherein said locking pin (154) of said lock (150) extends through said slot (177).

Abstract
Forceps for performing endoscopic or arthroscopic surgery include a body assembly, a tube assembly, and a pair of handles that pivot with respect to the body. The tube assembly is removably attached to the body assembly. The tube assembly includes a hollow tube and a tip assembly. The tip assembly includes an electrode or a blade for performing the surgery. The tip assembly and the blade are connected to the body and the handles by a cable. As the handles pivot, the cable slides within the tube to move the blade. When a different tube assembly (i.e., a bipolar or a monopolar electrode) or another style of tip assembly are desired, the installed one is removed and replaced by a new tube assembly or tip assembly as desired.
