Crimp And Release Of Suture Holding Buttress Material
First Claim
1. A surgical instrument comprising:
- a handle having a movable part mounted to the handle;
an elongate tubular member extending distally from the handle member;
an end effector assembly mounted on a distal end of the elongate tubular member, the end effector assembly including a first member having an underside and a top side, the underside having a face;
a strip of buttress material positioned against the face;
a retention component having a backspan and first and second ends extending from the backspan, the backspan being positioned across the strip of buttress material and the first end extends from the underside to the top side of the first member; and
a retention member movably mounted on the top side of the first member, wherein the first end of the retention component is releasably secured between a distal face of the retention member and a proximal face of the first member.

Abstract
A mechanism is provided for crimping and releasing a suture securing a strip of buttress material to an end effector. The mechanism includes a retention member movably mounted within the end effector. The retention member is movable from a first position crimping the suture to the end effector to a second position releasing the suture from the end effector. The mechanism additionally includes a follower member, engageable with the retention member, and movable in response to actuation of a surgical instrument to move the retention member between the first and second positions. A lock mechanism is also provided to secure the retention member in the first position. The follower member operates to disengage the lock mechanism.

16. The surgical instrument as recited in claim 15, wherein the movable part is operable to move the retention member from a first position securing the retention component between a distal face of the retention member and a proximal face of the first member to a second position allowing the retention member to move away from the first and second ends of the retention component.
