First Claim
Patent Images
1. A surgical instrument for performing an anastomosis, comprising:
- a housing having proximal and distal ends;
a shaft extending from the distal end of the housing;
an actuator attached to the housing;
a disposable loading unit configured for selective attachment to the shaft, the disposable loading unit including;
a fastener support member configured and dimensioned to support an array of surgical fasteners; and
a fastener pusher member which is movable through a firing stroke in response to movement of the actuator to deform the surgical fasteners.

Abstract
A surgical instrument for performing an anastomosis includes a housing having proximal and distal ends and a shaft extending from the distal end of the housing. The instrument also includes an actuator attached to the housing and a disposable loading unit configured for selective attachment to the shaft. The disposable loading unit includes a fastener support member configured and dimensioned to support an array of surgical fasteners thereon and a fastener pusher member which is movable through a firing stroke in response to movement of the actuator to deform the surgical fasteners.

9. A method of performing a vascular anastomosis between first and second vessels comprising the steps of:
-
providing a surgical instrument which includes;
a housing having proximal and distal ends with a shaft extending from the distal end of the housing;
an actuator attached to the housing;
a disposable loading unit configured for selective attachment to the shaft, the disposable loading unit having a passageway defined therethrough and including;
a fastener support member configured and dimensioned to support an array of surgical fasteners at a distal end thereof, the surgical fasteners having proximal and distal tips; and
a fastener pusher member which is movable through a firing stroke in response to movement of the actuator to deform the surgical fasteners;
inserting the first vessel through the passageway and everting an end of the first vessel over the distal end of the fastener support member adjacent the distal tips of the surgical fasteners;
inserting the fastener support member and the everted end of the first vessel into an opening in a sidewall of the second vessel such that the proximal tips of the surgical fasteners are adjacent the opening;
connecting the disposable loading unit to the shaft; and
actuating the actuator to deform the surgical fasteners to secure the first and second vessels in fluid communication with one another.
