LIGATING CLIP WITH INTEGRAL INTERLOCKING LATCH MECHANISM

摘要

A polymeric, surgical clip (12) having first and second curved legs (22, 24)joined at their proximal ends by a flexible hinge (26) section and movablefrom an open position to a closed position for clamping a vessel betweencurved opposing inner surfaces. The first leg terminates at its distal end ina female locking member comprising a resilient inwardly turned hook having arecess in the mouth of the hook (41), and the second leg member terminates ina male locking member complimentary to the female locking member andcomprising a detent such that when the first and second leg members are movedfrom an open position to a closed position about the hinge section the hookmember will deflect about the distal end of the second leg member therebyengulfing the male locking member in the mouth of the hook and matinglyengaging the detent in the recess thereof, thus securely locking the clip inthe closed position. The locking feature provides greater closure security tothe clip when clamping large diameter or uncompressible tissue.
