Abstract
The present disclosure relates to an apparatus for endoscopic application of surgical clips to body tissue. The apparatus includes a handle portion, an elongated tubular member, one or more surgical clips, a jaw assembly and a locking cam driver. The elongated tubular member extends distally from the handle portion and defines a longitudinal axis. The surgical clips are disposed within the tubular member. The locking cam driver includes a bifurcated distal end portion that has a pair of angled camming surfaces to facilitate closure of the jaw assembly.

17. 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 each angled camming surface of the locking cam driver is substantially complementary of a 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, wherein the angle of the angled camming surfaces of the locking cam driver is different than the angle of the angled camming surfaces of the jaw assembly to provide an offset angled configuration. - View Dependent Claims (18, 19)

20. An apparatus for application of surgical clips to body tissue, the apparatus comprising:
-
a jaw assembly including first and second jaw members, each of the first and second jaw members including a raised element having an angled camming surface defining a first angle, the jaw assembly being movable between a spaced, open position and an approximated, substantially closed position; and a locking cam driver including a pair of angled camming surfaces each defining a second angle different from the first angle, wherein each angled camming surface of the locking cam driver is substantially complementary of a 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. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
