Medical instrument
First Claim
1. A hydraulically actuated endoscopic medical instrument, comprising:
- an elongated shaft including a proximal end and a distal end and generally defining a longitudinal shaft axis at the distal end thereof;
an elongated end effector at the distal end of the elongated shaft, at least a portion of the end effector extending at an angle to another portion of the end effector;
a handle portion at the proximal end of the elongated shaft; and
a fluid flow path extending between the handle portion and the end effector through the elongated shaft.

Abstract
A hydraulically actuated medical instrument includes an elongated shaft having proximal and distal ends, a hydraulically actuated end effector at the distal end of the shaft and a fluid flow path extending through the shaft to the end effector. The shaft may be capable of an angled configuration where at least a portion of the shaft is manually movable to a direction in which it extends at an angle to another portion of the shaft. The end effector is not limited to a linear configuration and at least a portion of an elongated end effector extends at an angle relative to another portion of the end effector as is needed or desirable for the particular procedure to be performed.
