Bipolar forceps having monopolar extension
First Claim
1. An endoscopic forceps, comprising:
- a housing having a shaft affixed thereto, the shaft including first and second jaw members attached to a distal end thereof;
an actuator for moving jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween;
a source of electrosurgical energy connected to each jaw member such that the jaw members are selectively capable of operating in a bipolar mode which enables the jaw members to conduct bipolar energy through tissue held therebetween to treat tissue; and
a monopolar element housed within at least the first jaw member and selectively movable from a first position within the first jaw member to a second position distal to the first jaw member, the monopolar element being connected to the source of electrosurgical energy and being selectively activateable independent of the jaw members.

Abstract
An endoscopic forceps for treating tissue includes a housing having a shaft affixed thereto which has first and second jaw members attached to a distal end thereof. The forceps also includes an actuator for moving jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members is connected to a source of electrosurgical energy such that the jaw members are selectively capable of operating in a bipolar mode which enables the jaw members to conduct bipolar energy through tissue held therebetween to treat tissue. The forceps also includes a monopolar element housed within the first jaw member which is selectively movable from a first position within the first jaw member to a second position distal to the first jaw member. The monopolar element is connected to the source of electrosurgical energy and is selectively activateable independent of the bipolar mode.

10. A method for treating tissue with electrosurgical energy from an electrosurgical generator, the method comprising the steps of:
-
providing an endoscopic forceps comprising; a housing having a shaft affixed thereto, the shaft including first and second jaw members attached to a distal end thereof; an actuator for moving jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween; a monopolar element housed within at least the first jaw member and selectively movable from a first position within the first jaw member to a second position distal to the first jaw member; and a return electrode placed in contact with patient tissue; connecting each jaw member, the monopolar element and the return electrode to the electrosurgical generator; grasping tissue between the jaw members; selectively activating the jaw members to treat tissue disposed between the jaw members in a bipolar fashion; and selectively activating the monopolar element and the return electrode independent of the jaw members to treat tissue in a monopolar fashion. - View Dependent Claims (11, 12, 13)
