ABSTRACT:
The instrument is used in laparoscopic tubal cauterization whereby a fallopian tube is completely blocked by coagulation and comprises: an elongated narrow sheath; an electrically insulated separator means slidably mounted in the sheath; and a pair of bipolar electrodes secured in diametrically opposite grooves extending longitudinally of the sheath. Each electrode defines at one end thereof a prong extending outwardly from one end of the sheath; the prongs are spaced from one another to define a first tube-receiving position whereby a tube may be received therebetween; the prongs may be moved to a second tube-squeezing position by slidably retracting the separator means in the sheath. The opposite end of each electrode is adapted for electrical connection to an external source of cauterizing current.
