A surgical clip of plastics material for performing sexual sterilization comprises two jaws 12,14 hinged to move from an open position to the closed position shown, in which a Fallopian tube 18 is occluded. A catch mechanism 20 engages when the jaws reach their closed position, and locks the jaws closed. The location of the catch mechanism 20 in the vicinity of the hinge 16 ensures that it does not contact the vulnerable mesosalpinx 58, thus reducing the risk of bleeding. Interdigitated teeth 26,36 and a curved, springy tongue 54 prevent the tube 18 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 58. A resilient lining 22 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 biassing also enables the clip to be located firmly in an applicator before closure. |
