Patent ID: 8715277

Claim:
A surgical instrument comprising: an end effector comprising a distal end and a proximate end, wherein the end effector comprises: a first jaw member comprising a distal end and a proximate end, wherein the proximate end of the first jaw member comprises a pin; a second jaw member opposing the first jaw member, wherein the second jaw comprises a distal end and a proximate end, wherein the proximate end of the second jaw member comprises a multi-lobed cam slot with at least three lobes, wherein the pin of the first jaw member is disposed and moveable within the multi-lobed cam slot between the three lobes, wherein the first jaw member is moveable relative to the second jaw member such that the first and second jaw members are transitionable between an open position and a closed position, such that the first and second jaw members are in the open position when the pin of the first jaw member is in a first lobe of the multi-lobed cam slot and the first and second jaw members are in the closed position when the pin of the first jaw member is in a second lobe of the multi-lobed cam slot, and wherein the pin of the first jaw member moves into a third lobe of the multi-lobed cam slot when the pin transitions from the first lobe to the second lobe; and a latch at a distal end of the end effector for latching the distal end of the first jaw member to the distal end of the second jaw member when the first and second jaw members are in the closed position.
