Patent Images
1. Surgical fastener applying apparatus comprising:
- a distal fastener applying assembly including (a) a fastener holding part initially containing at least one surgical fastener, (b) an anvil part movable relative to the fastener holding part for clamping tissue to be fastened between the fastener holding part and the anvil part, and (c) first means for driving the fastener from the fastener holding part at least partly through the clamped tissue to the anvil part;
a proximal actuator assembly including second means for producing the work necessasry to operate the first means; and
a longitudinal shaft assembly for connecting the fastener applying assembly to the actuator assembly, for supporting the fastener applying assembly relative to the actuator assembly, and for operatively transmitting the work produced by the second means to the first means, the shaft assembly including a joint for allowing rotation of the fastener applying assembly relative to the actuator assembly about each of three mutually orthogonal axes.

23. Surgical fastener applying apparatus comprising:
-
a distal fastener applying assembly including (a) a fastener holding part initially containing at least one surgical fastener, (b) an anvil part movable relative to the fastener holding part for clamping tissue to be fastened between the fastener holding part and the anvil part, and (c) first means for driving the fastener from the fastener holding part at least partly through the clamped tissue to the anvil part; a proximal actuator assembly including (a) second means for producing at least part of the work required for causing the relative motion of the fastener holding part and the anvil part which clamps the tissue, and (b) third means for producing the work required for operating the first means; and a longitudinal shaft assembly connected between the fastener applying and actuator assemblies and including (a) a longitudinal shaft member including first joint means for allowing rotation of the fastener applying assembly relative to the actuator assembly about each of three mutually orthogonal axes, (b) a first member for operatively transmitting the work produced by the second means to the fastener applying assembly, and (c) a second member for operatively transmitting the work produced by the third means to the first means. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
