Interchangeable clip applier

摘要

A surgical device for clipping tissue can include an actuator, such as a handle or a robotic arm, for example, and a replaceable end effector including a plurality of clips contained therein. After the replaceable end effector has been used, the end effector can be detached from the actuator and a new end effector can be operably coupled with the actuator. Each replaceable end effector can include a firing drive for advancing clips into a receiver of the end effector and a crimping drive configured to deform a clip positioned within the receiver.

1. A clip applier loading unit, said clip applier loading unit configured to be releasably attached to a distal portion of an elongate shaft of a surgical instrument, said clip applier load unit comprising:
a shaft, comprising:
a distal end;a proximal end; anda frame comprising a frame connector configured to be releasably attached to a frame of the surgical instrument; a replaceable magazine configured to be releasably attached to said clip applier loading unit, wherein said magazine comprises a plurality of clips; an end effector extending from said distal end of said shaft, wherein said end effector comprises:
a first jaw;a movable second jaw; anda receiver defined between said first jaw and said second jaw, wherein said receiver is configured to receive a said clip, and wherein said second jaw is movable toward said first jaw to deform a said clip positioned in said receiver during a crimping stroke; and a firing drive, comprising:
a distal portion configured to advance a said clip into said receiver during an advancing stroke, wherein said crimping stroke is separate and distinct from said advancing stroke; anda proximal portion comprising a drive connector configured to be releasably attached to a driver of the surgical instrument.
