Abstract

A surgical clip of plastics material for performing sexual sterilization comprises two jaws hinged to move from an open position to the closed position shown, in which a Fallopian tube is occluded. A catch mechanism engages when the jaws reach their closed position, and locks the jaws closed. The location of the catch mechanism in the vicinity of the hinge ensures that it does not contact the vulnerable mesosalpinx, thus reducing the risk of bleeding. Interdigitated teeth and a curved, springy tongue prevent the tube escaping from the clip as the jaws close. The teeth are rounded and are loosely interdigitated to reduce the risk of damage to the mesosalpinx. A resilient lining on the jaw biasses them apart. The clip will spring back open during application if it has not been closed sufficiently to engage the catch mechanism. The biasing also enables the clip to be located firmly in an applicator before closure.
