<p>A surgical instrument consisting of three concentric tubes (11, 12, 13), with the outer and inner tubes made of electrical current conducting material which are in turn connected to a bipolar current generator. When the tips (14, 15) of such tubes are placed against tissue a current will flow therebetween and cauterize such tissue. To prevent short circuiting between the two conductive tips the third or middle tube constitutes an insulator (18). A suction tube (22) equipped with a suction regulator is integral with the instrument and has open communication with the current conductive tips which are designed to be longitudinally separated by an open slot that allows continuous air flow therebetween and into the suction tube during the surgical procedure.</p> |
