Patent Images
1. A clip applier loading unit, comprising:
- a shaft, comprising;
a distal end;
a proximal end; and
a frame comprising a frame connector configured to be releasably attached to a frame of an actuator;
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; and
a 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; and
a firing drive, comprising;
a distal portion configured to advance a said clip into said receiver; and
a proximal portion comprising a drive connector configured to be releasably attached to a driver of the actuator.

Abstract
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.

13. A clip applier loading unit, comprising:
-
a shaft, comprising; a distal end; a proximal end; a frame comprising a frame connector configured to be releasably attachable to and detachable from a frame of an actuator unit; and a bearing; a plurality of clips; an end effector extending from said distal end of said shaft, wherein said end effector comprises; a first jaw; a second jaw movable relative to said first jaw; and a receiver defined between said first jaw and said second jaw, wherein said receiver is configured to receive a said clip; a reciprocating rotary firing drive, comprising; a rotatable driver comprising a thread, wherein said rotatable driver is rotatably supported by said bearing; and a firing nut threadably engaged with said thread of said rotatable driver, wherein said firing nut is advanceable toward said distal end when said driver is rotated in a first direction, wherein said firing nut is retractable away from said distal end when said driver is rotated in a second direction opposite said first direction, and wherein said firing nut is configured to advance a said clip into said receiver when said firing nut is advanced toward said distal end. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
