First Claim
Patent Images
1. An apparatus for endoscopic application of surgical clips to body tissue, the apparatus comprising:
- a handle portion;
an elongated tubular member extending distally from the handle portion and defining a longitudinal axis;
at least one surgical clip disposed within the tubular member;
a jaw assembly including first and second jaw members mounted at a distal end of the elongated tubular member, the first and second jaw members defining a plane therebetween, each of the first and second jaw members including a raised element having an angled camming surface, the jaw assembly being movable between a spaced, open position and an approximated, substantially closed position; and
a locking cam driver including a bifurcated distal end portion having a pair of angled camming surfaces, wherein the angle of the angled camming surfaces of the locking cam driver is different than an angle of a respective angled camming surface of the jaw assembly to provide an offset angled configuration, wherein each angled camming surface of the locking cam driver is substantially complementary of the respective angled camming surface of the jaw assembly, each angled camming surface of the locking cam driver configured to engage a corresponding angled camming surface of the jaw assembly to move the first and second jaw members from the spaced, open position to the approximated, substantially closed position to thereby form a surgical clip.
