Abstract
Endoscopic reposable surgical clip appliers including a reusable handle assembly and at least one reusable shaft assembly.
Claims8
A reposable surgical clip applier, comprising:
- a handle assembly including:
- a receiver assembly including an outer collar and an inner tubular member;
- and
- a rotation knob disposed about the receiver assembly, the rotation knob slidable relative to the inner tubular member and engaged to the outer collar such that sliding of the rotation knob relative to the inner tubular member between a proximal position and a distal position slides the outer collar relative to the inner tubular member between a proximal locked position and a distal unlocked position;
- an endoscopic clip-applying assembly insertable into the inner tubular member, wherein, with the endoscopic clip-applying assembly inserted into the inner tubular member, the rotation knob is slidable from the distal position to the proximal position to thereby slide the outer collar from the distal unlocked position to the proximal locked position to lock the endoscopic clip-applying assembly within the inner tubular member, wherein the receiver assembly is configured to releasably engage the endoscopic clip-applying assembly;
- and
- at least one ball bearing configured for insertion partially through a respective aperture defined within the inner tubular member, each ball bearing configured for receipt within a corresponding aperture defined within the endoscopic clip-applying assembly to lock the endoscopic clip-applying assembly within the inner tubular member.

A reposable surgical clip applier, comprising:
- a handle assembly including:
- a receiver assembly including an outer collar and an inner tubular member, wherein the inner tubular member defines a proximal aperture and a distal aperture;
- and
- a rotation knob disposed about the receiver assembly, wherein the rotation knob includes a locking pin operably coupled to the inner tubular member, the rotation knob slidable relative to the inner tubular member and engaged to the outer collar such that sliding of the rotation knob relative to the inner tubular member between a proximal position and a distal position slides the outer collar relative to the inner tubular member between a proximal locked position and a distal unlocked position, the locking pin being configured for engagement within the proximal aperture of the inner tubular member to lock the rotation knob in the proximal position and being configured for engagement within the distal aperture of the inner tubular member to lock the rotation knob in the distal position;
- and
- an endoscopic clip-applying assembly insertable into the inner tubular member, wherein, the receiver assembly is configured to releasably engage the endoscopic clip-applying assembly,
- wherein, with the endoscopic clip-applying assembly inserted into the inner tubular member, the rotation knob is slidable from the distal position to the proximal position to thereby slide the outer collar from the distal unlocked position to the proximal locked position to lock the endoscopic clip-applying assembly within the inner tubular member.
