Lock bar spring and clip for implant deployment device

摘要

A system for closing an aperture in a biological tissue includes an implant deployment device having a frame arm, a clip connected to the frame arm, and a lock bar including a protrusion. The protrusion extends away from the frame arm and is configured for selectively holding the clip in an open position or a closed position. A surgical implant is releasably attached to the frame arm. The clip retains the surgical implant in contact with the frame arm when the clip is in the closed position and the clip allows the surgical implant to be separated from the frame arm when the clip is in the open position.

1. A surgical instrument comprising:
a proximal portion; a distal portion including a frame arm; a clip rotatably coupled to the frame arm and configured to releasably retain a surgical implant to the frame arm; and a monolithic lock bar including a body and a protrusion, the protrusion extending laterally offset from the body and the frame arm, wherein the protrusion is configured for selectively holding the clip in a predetermined position, wherein the protrusion is shaped to allow the clip to deflect the protrusion inwardly towards the body and towards the frame arm, thereby allowing the clip to rotate over the protrusion from an open position to a closed position.
