Patent ID: 8784418

Claim:
An end effector assembly for an endoscopic surgical instrument, the end effector assembly comprising: a pair of jaw members disposed in opposing relation relative to one another, at least one of the jaw members moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween, each jaw member defining an arcuate configuration and including: a proximal segment; a distal segment coupled to the proximal segment and moveable with respect to the proximal segment between a use position, wherein the proximal segment and the distal segment cooperate to define the arcuate configuration of the jaw member, and an insertion position, wherein the distal segment is offset relative to the proximal segment to interrupt the arcuate configuration of the jaw member; a biasing member disposed between the proximal and distal segments and configured to bias the distal segment towards the use position; and a rod disposed within the proximal segment and moveable between a retracted position, wherein the rod is spaced-apart from the distal segment, and an extended position, wherein the rod extends from the proximal segment and into contact with the distal segment to urge the distal segment against the bias of the biasing member to the insertion position.
