Abstract:
1. A surgical instrument for performing an anastomosis, which comprises: a housing having a pair of opposed housing portions each having a proximal end and a distal end, the proximal ends being pivotally connected to one another and the distal ends being selectively movable toward and away from each other to define an approximation distance therebetween; an approximation control mechanism operatively associated with the first and second opposed housing portions to selectively move the distal ends of the opposed housing portions toward and away from each other, the approximation control mechanism including a standoff member which connects the first and second housing portions and an approximation adjusting member that engages the standoff member, wherein one of the first and second opposed housing portions is movable relative to the other of the opposed housing portions in response to movement of the adjusting member with respect to the standoff member to selectively set a maximum approximation distance; a fastener support member attached to the distal end of the housing configured and dimensioned to releasably retain a plurality of surgical fasteners; and an actuating assembly operatively associated with the fastener support member to facilitate deformation of at least a portion of the surgical fasteners.
