BIPOLAR FORCEPS HAVING MONOPOLAR EXTENSION Abstract An endoscopic forceps (10), comprising: a housing (20) having a shaft (12) affixed thereto, the shaft (12) including first and second jaw members (110, 120) attached 5 to a distal end thereof, the first jaw member (110) extending distally relative to the second jaw member (120); an actuator for moving jaw members (110, 120) relative to one another from a first position wherein the jaw members (110, 120) are disposed in spaced relation relative to one another to a second position wherein the jaw members (110, 120) cooperate to grasp tissue therebetween; a source of electrosurgical energy connected to io each jaw member (110, 120) such that the jaw members (110, 120) are selectively capable of operating in a bipolar mode which enables the jaw members (110, 120) to conduct bipolar energy through tissue held therebetween to treat tissue; and a control switch (200) which, upon selective activation thereof, deactivates the second jaw member (120) and activates the first jaw member (110) with a first electrical potential a return electrode with 15 a different electrical potential to enable the first jaw member (110) to selectively treat tissue in a monopolar fashion. |
