A laparoscopic sterilization instrument comprises an excisor 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a portion of a patient's oviduct and a receptacle for holding the excised oviduct portion until the instrument has been withdrawn from the patient's abdomen.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 sterilization procedure, for the protection of patient and physician alike. The instrument includes first and second elongate parts attached to each other for relative movement parallel to their longitudinal axes to operate the excisor 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. The instrument is operable by a physician to work the excisor means and an applicator for applying a clip in a single action. |
