A forceps is provided. The forceps includes a housing having a shaft that extends therefrom. The bipolar forceps also includes a hydraulic mechanism that includes a fluid line and a plunger operatively coupled to the fluid line. The plunger is translatable within at least a portion of the shaft from a proximal position to a distal position. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of first and second jaw members biased in an open configuration. Each of the first and second jaw members configured to receive at least a portion of the plunger when a fluid is caused to flow within the fluid line such that the first and second jaw members move from an open position for positioning to a closed position for grasping tissue.
1. A forceps adapted to connect to a source of electrosurgical energy for performing an electrosurgical procedure comprising: a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough;a hydraulic mechanism that includes a fluid line;a plunger assembly operatively
1. A forceps adapted to connect to a source of electrosurgical energy for performing an electrosurgical procedure comprising: a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough;a hydraulic mechanism that includes a fluid line;a plunger assembly operatively coupled to the fluid line, the plunger assembly having first and second plungers, the plunger assembly translatable along the longitudinal axis and within at least a portion of the shaft; andan end effector assembly, operatively connected to a distal end of the shaft, having a pair of first and second jaw members biased in an open configuration, each of the first and second jaw members including at least one aperture defined at a proximal end thereof configured to receive at least a portion of the first plunger,wherein the first plunger is configured to selectively engage the first and second jaw members to move the first and second jaw members from the open configuration to a clamping position wherein the first and second jaw members cooperate to grasp tissue therebetween to treat the tissue,wherein the second plunger is translatable with respect to the first plunger and configured to selectively engage at least one of the first and second jaw members to sever the treated tissue,and wherein the first plunger includes at least two prongs extending from a proximal portion thereof, each one of the at least two prongs configured to engage a different one of the at least one aperture associated with each of the first and second jaw members. 2. A forceps according to claim 1, wherein each of the first and second jaw members are pivotable about a pivot pin located at the distal end of the shaft. 3. A forceps according to claim 1, wherein a biasing member is operably disposed on the first plunger to bias the first plunger in an uncompressed state. 4. A forceps according to claim 1, wherein a knife blade is operatively coupled to the second plunger and is configured for translatable motion within a knife slot defined within at least one of the first and second jaw members. 5. A method for performing an electrosurgical procedure, the method comprising: providing an electrosurgical instrument including:a hydraulic mechanism that includes a fluid line and a plunger assembly operatively coupled to the fluid line, the plunger assembly having first and second plungers, the first plunger including at least two prongs extending from a proximal portion thereof; andan end effector assembly having a pair of first and second jaw members biased in an open configuration, each of the first and second jaw members including at least one aperture defined at a proximal end thereof configured to receive at least a portion of the first plunger, each one of the at least two prongs configured to engage a different one of the at least one aperture associated with each of the first and second jaw members;positioning tissue between the pair of first and second jaw members;actuating the hydraulic mechanism to cause the first and second jaw members to move towards each other such that tissue is grasped therebetween;applying electrosurgical energy to the jaw members to effectively electrosurgically treat tissue therebetween; andactuating the hydraulic mechanism to sever the electrosurgically treated tissue. 6. A method according to claim 5, wherein providing an electrosurgical instrument further includes providing the first plunger with a biasing member to bias the first plunger in an uncompressed state. 7. A method according to claim 5, wherein providing an electrosurgical instrument further includes providing the second plunger with a knife blade that is configured for translatable motion within a knife slot defined within at least one of the first and second jaw members. 8. A method according to claim 7, wherein actuating the hydraulic mechanism to sever the electrosurgically treated tissue further includes actuating the hydraulic mechanism to cause the second plunger to translate the knife blade to sever the electrosurgically treated tissue.
