ABSTRACT:
A device is disclosed for use in a laparoscopic tubal cauterization for blocking the fallopian tubes of a patient. The device comprises a substantially tubular body member having a piston slidably mounted therein. A spring urges the piston to a first position relative to the body member. A button extends from one end of the body member for moving the piston to a second position against the urging of the spring. First and second electrodes are incorporated for either monopolar or bipolar treatment of the living tissue. The first and second electrodes are disposed to grasp the living tissue when the piston is in the first position and to release the living tissue when the piston is in the second position. The invention includes a circuit breaker for terminating continuity when the piston is disposed in the second position. An activating switch is disabled when the piston is in the second position. The invention provides a dual series switch system of circuit interruption when the electrodes release the living tissue.
