Abstract
A hydraulically operated surgical instrument comprising a jaw assembly including a hollow tubular outer elongate member with a first jaw member fixed to and generally radially projecting from its first end; and an inner elongated member within and extending from the first end of the outer elongate member and having a second jaw member fixed to and generally radially projecting from its end adjacent the first jaw member. The jaw assembly is mounted on a frame of the instrument with the first and second jaw members in opposed relationship and can be manually rotated about its axis relative to the frame and releasably locked in a desired position. Manual squeezing of a trigger causes movement of the jaw members between open and closed positions through a hydraulic system which limits the maximum pressure that can be applied between the jaw members.
