Ligating clip with integral interlocking latch mechanism
First Claim
1. A surgical clip with an interlocking latch mechanism, comprising:
- a first leg and a second leg, each of said legs having an inner vessel-clamping surface and an outer surface, said inner surfaces being positioned in opposition to each other;
a flexible hinge section integrally disposed between and joining the proximal ends of said first and second legs; and
a female locking member positioned on the distal end of said first leg and comprising a resilient inwardly turned hook defining a recess in a mouth of said hook, and a male locking member positioned on the distal end of said second leg comprising at least one detent extending therefrom, said female and male locking members being formed whereby when said first and second leg members are moved from an open position to a closed position about said hinge section, said resilient hook of said female locking member is urged open to receive the detent of said male locking member in the recess thereof so as to removably lock said first and second leg members of said surgical clip in said closed position; and
further comprising a gusset within the mouth of said hook,wherein the at least one detent extending outwardly from said male locking member comprises two spaced-apart detents each having an inwardly turned lip extending generally toward said flexible hinge section for lockingly engaging said recess in the mouth of said hook.

Abstract
A polymeric, surgical clip having first and second curved legs joined at their proximal ends by a flexible hinge section and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces. The first leg terminates at its distal end in a female locking member comprising a resilient inwardly turned hook having a recess in the mouth of the hook, and the second leg member terminates in a male locking member complimentary to the female locking member and comprising a detent such that when the first and second leg members are moved from an open position to a closed position about the hinge section the hook member will deflect about the distal end of the second leg member thereby engulfing the male locking member in the mouth of the hook and matingly engaging the detent in the recess thereof, thus securely locking the clip in the closed position. The locking feature provides greater closure security to the clip when clamping large diameter or uncompressible tissue.
