1. A laparoscopic forceps comprising;
- a handle comprising left and right bow members pivotally connected to a mounting core and adapted to engage a finger and thumb;
a tubular housing extending axially from the handle and carrying an actuation rod;
a jaws mechanism disposed at the end of the tubular housing remote from the handle engaged to the actuation rod and arranged so that the jaws may be opened or closed by actuation of the handle;
a switch mechanism moveable between locked and unlocked positions, adapted when locked to allow closure and prevent opening of the jaws, and when unlocked to allow free opening and closing of the jaws; and
a slideable release member having a first position and a release position, wherein said slidable release member, while in said release position, permits free opening of the jaws with the bow members while said switch mechanism is in the locked position.
