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, each jaw member adapted to connect 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;
a first actuator operably associated with the housing which moves the 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, the monopolar element being adapted to connect to the source of electrosurgical energy and being selectively activatable independent of the jaw members; and
a second actuator operatively coupled to the housing which operates to extend the monopolar element from the first position within the first jaw member to the second position distal to the first jaw member.

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.

8. 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, the first jaw member extending distally relative to the second jaw member, each jaw member adapted to connect 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; an actuator operably coupled to the housing which moves 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; and a control switch adapted to operably communicate with the source of electrosurgical energy which, upon selective activation thereof, deactivates the second jaw member and activates the first jaw member with a first electrical potential a return electrode with a different electrical potential to enable the first jaw member to selectively treat tissue in a monopolar fashion. - View Dependent Claims (9)

10. 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, the first and second jaw members each including a tapered distal end, each jaw member adapted to connect 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 an actuator operably associated with the housing which moves the 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; and a control switch adapted to operably communicate with the source of electrosurgical energy which, upon selective activation thereof activates the first jaw member and the second jaw member with a first electrical potential, the control switch also activating a return electrode with a different electrical potential which enables the first and second jaw members to selectively treat tissue in a monopolar fashion. - View Dependent Claims (11)
