Publication number: 20220047271Abstract: A clip applier may be configured to apply a surgical clip to tissue. The clip applier may include a first jaw member, a second jaw member, and a stabilizing member, each configured to engage the surgical clip. The stabilizing member may be configured to move longitudinally with respect to the clip applier from a first position at least partially between the first and second jaw members to a second position at least partially between the first and second jaw members. The longitudinal movement of the stabilizing member may be constrained to longitudinal movement between the first and second positions. The stabilizing member may include first and second sidewalls on a distal portion, where the first and second sidewalls are configured to stabilize the surgical clip in a lateral direction. The clip applier may include a hinge pin received in a longitudinal channel of the stabilizing member.Type: ApplicationFiled: November 1, 2021Publication date: February 17, 2022Inventor: Carson J.
