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.
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 electro surgical energy such that the jaw members are selectively capable of conducting
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 electro surgical energy such that the jaw members are selectively capable of conducting energy through tissue held therebetween to treat tissue;an actuator operably associated with the housing for moving 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 knife that is selectively moveable within a knife channel defined within at least one of the first and second jaw members to cut tissue disposed between the first and second jaw members;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 adapted to connect to a source of electrosurgical energy and selectively activateable independent of the jaw members; anda trigger configured to move proximally to a first position to move the knife to divide tissue disposed between the jaw members and to move further proximally to a second position to extend the monopolar element from the first position within the first jaw member to the second position distal to the first jaw member, wherein the trigger is configured to selectively move the monopolar element from the first position to the second position when the jaw members are in the first position and wherein the trigger is configured to move to a third position proximal to the second position to selectively cause the source of electrosurgical energy to supply energy to the monopolar element. 2. An endoscopic forceps according to claim 1 wherein the forceps is a vessel sealing forceps and at least one of the jaw members includes at least one non-conductive stop member disposed thereon configured to control the distance between the first and second jaw members when tissue is held therebetween. 3. An endoscopic forceps according to claim 1, wherein the trigger is configured to selectively cause a source of electrosurgical energy to supply energy to the monopolar element. 4. An endoscopic forceps according to claim 1, wherein the monopolar element is configured to return to the first position upon movement of the trigger distally from the second position. 5. An endoscopic forceps according to claim 1, wherein upon movement of the monopolar element to the second position, a supply of electrosurgical energy to the jaw members is deactivated and the supply of electrosurgical energy to the monopolar element is activated. 6. A system for an electrosurgical forceps, comprising: an instrument housing having a shaft affixed thereto, the shaft including first and second jaw members attached to a distal end thereof;an actuator operably associated with the housing for moving 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;an energy source adapted to provide energy to each jaw member such that the jaw members are configured to conduct bipolar energy through tissue grasped therebetween;a knife that is selectively moveable within a knife channel defined within at least one of the first and second jaw members to cut tissue grasped between the first and second jaw members;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 connected to the energy source and selectively activateable independent of the jaw members; anda trigger moveable from a neutral position to a first position to move the knife to divide tissue grasped between the jaw members and from the first position to a second position proximal to the first position to extend the monopolar element from the first position within the first jaw member to the second position distal to the first jaw member, wherein the trigger is configured to move to a third position proximal to the second position to selectively cause the energy source to supply energy to the monopolar element.
