Abstract

An instrument for applying clips in surgery having an operating handle with operating components and a clip cartridge with clip applying mechanism. The handle operating components generate reciprocal linear motion imparted to the clip applying mechanism and accommodate rotation of the cartridge about a cartridge axis. An anti-backup mechanism constrains operating components to complete first and second strokes of reciprocal linear motion.

Claims

1. An anti-backup mechanism for a device having liner reciprocating motion through forward and reverse strokes, the anti-backup mechanism comprising a drum, a translator assembled with the drum for linear reciprocating movement through said strokes, the translator having first and second means defining the limits of reciprocating motion, and an anti-backup disc mounted on the drum and cooperating with the translator first and second means to ensure the forward and reverse strokes of linear excursion of the translator are completed without backup movement.
