ABSTRACT:
A surgical instrument for sterilizing women by the ligation of the fallopian tubes comprises a probe having tongs with gripper means for engaging the tubes and means for directing a coolant to the vicinity of the gripper means for freezing of the tubes including a heater for subsequently heating the tubes. The probe advantageously includes a hollow central tube with a flared outer end at the probe tip and has an interior portion defining an evaporation chamber in which a coolant is evaporated to reduce the temperature at this end. A so-called Semm tongs extends through the tube and includes gripper elements at the flared end of the tube which may be moved outwardly to grip the fallopian tube of a woman to withdraw it into the flared end of the hollow tube where it may be frozen. The tip also includes a heater for reheating the frozen tubes. The opposite end of the probe includes a handle portion having a mechanical and electrical connection for the transmission of a coolant therethrough and the electrical current for actuating the heater.
