STERILISING INSTRUMENT

摘要

A laparoscopic sterilisation instrument comprises excision means for excising a portion of a patient's oviduct and a receptacle for holding the excised oviduct portion until the instrument has been withdrawn from the patient's abdomen. The excised oviduct portion constitutes a full circumference biopsy that can be examined to confirm proper performance of the sterilisation procedure, for the protection of patient and physician alike. The instrument described includes first and second elongate parts defining longitudinal axes and distal and proximal ends, the parts being attached to each other for relative movement parallel to their longitudinal axes to operate the excision means. The first part is a rod and the second part is a sleeve within which the rod can move, the rod sliding longitudinally within the sleeve. Application means apply an occlusive device such as a clip or ring to the oviduct. The instrument is operable by a physician to work the excision means and the application means in a single action, the application means operating before the excision means during said action.
