Surgical instrument for joining tissue

摘要

A surgical instrument for surgically joining tissue is provided. The surgical instrument includes a handle assembly that includes an actuator member. An end effector is operatively disposed adjacent a distal portion of an elongated shaft of the surgical instrument. The end effector includes a first jaw member pivotably disposed with respect to a second jaw member. The end effector is movable between a first position where the jaw members are spaced from one another, and a second position where the jaw members are in an approximated position. Each of the first and second jaw members includes a respective longitudinal track. An actuation assembly is disposed in mechanical cooperation with the end effector, wherein actuation of the actuation member causes the actuation assembly to translate from a distal portion of the end effector towards a proximal portion of the end effector through the tracks in the first and second jaw members.

主权项

1. A surgical stapling instrument comprising:
an elongated body having a proximal end and a distal end; a cable movable within the elongated body, the cable having a proximal end and a distal end supporting a first coupling; a loading unit adapted to be releasably secured to the distal end of the elongated body, the loading unit including an end effector and an actuation member, the actuation member having a proximal end supporting a second coupling; and an actuation head supported in a distal end of the end effector, the actuation head being secured to a distal end of the actuation member such that proximal movement of the actuation member effects proximal movement of the actuation head within the end effector; wherein the first and second couplings are positioned such that when the loading unit is secured to the distal end of the elongated body, the first coupling is releasably coupled to the second coupling to secure the cable to the actuation member.
