Endoscopic forceps with thumb-slide lock release mechanism
First Claim
1. An electrosurgical device comprising:
- a) an elongated tubular member having a proximal end and a distal end;
b) a pair of jaws at said distal end of said elongated tubular member moveable between an open position and a closed position;
c) an actuating means operably connected to said proximal end of said elongated tubular member for actuating said pair of jaws between said open position and said closed position;
d) a selector means operably connected to said actuating means for selecting movement of said pair of jaws between a unidirectional mode and a bidirectional mode; and
e) a release means operably connected to said selector means for allowing bidirectional movement when said unidirectional mode is selected.

Abstract
The present invention is a electrosurgical device having an elongated tubular member with a cutting and coagulating arrangement at its distal end and a handle at its proximal end. The coagulating and cutting instrument consists of two electrode jaw members with cutting blade extending therebetween. The cutting blade is connected to a movable rod extending through the lumen of the tubular member. A first and second conductor pair extend through the lumen of the tubular member in a spaced apart parallel arrangement with the cutting instrument and its movable rod extending therebetween. The first and second conductor pairs form the forceps jaws. The forceps jaws have a slot for receiving the cutting instrument therebetween. The handle member affixed to the proximal end of the tubular member includes a selector switch used for selecting a mode of movement of the jaws so that either unidirectional mode or a bidirectional mode can be selected. The device further includes a release connected to the selector means for restoring bidirectional movement of the jaw mechanism if the unidirectional mode had earlier been selected.
