Abstract
An end effector for a surgical clip applier includes a body having, a clip revolver rotatably coupled within a bore of the body and containing one or more surgical clips, a torsion member constrained between the body and the clip revolver to exert rotational force on the clip revolver, and a clip advancer that is slidingly coupled within an inner bore of the clip revolver. The inner bore of the clip revolver includes a plurality of grooves in which the clip advancer may translate. The clip advancer aligns with a distal-most surgical clip as it travels within a first of the grooves. The torsion member rotates the clip revolver as the clip advancer travels distally from the first groove so that the clip advancer travels into a second groove of the grooves, such that the clip advancer is in alignment with a second distal-most surgical clip.
