Abstract: An electrosurgical forceps includes first and second shaft members and first and second jaw members extending distally from the respective first and second shaft members. A pivot couples the first and second shaft members with one another such that the first and second shaft members are movable relative to one another between a spaced-apart position and an approximated position to move the first and second jaw members relative to one another between an open position and a closed position. The jaw members are configured to facilitate tissue treatment, tissue division, and blunt tissue dissection.

Abstract: A surgical instrument includes a housing, a shaft extending therefrom, an end effector assembly supported by the shaft, a movable handle, and a drive assembly. The drive assembly includes a translatable drive member for actuating the end effector assembly, and a torsion spring including first and second legs. The first leg is configured to translate through the housing in response to movement of the movable handle relative to the housing. The second leg is configured to translate through the housing in cooperation with the first leg to move the drive member longitudinally when a force acting on the drive member is less than a threshold force, and to remain in fixed position, thereby tensioning the torsion spring and retaining the drive member in fixed position when the force acting on the drive member is equal to or exceeds the threshold force.

Abstract: An end effector assembly for an electrosurgical instrument includes a pair of opposing first and second jaw members each including a jaw housing supporting a sealing plate disposed thereon and movable relative to one another to grasp tissue therebetween. The sealing plates adapted to connect to opposite potentials of an electrosurgical energy source and the sealing plate of the first jaw member having an open T-shaped configuration defining a channel along a length thereof. A plasma blade is disposed within the channel and extends to a distal end portion thereof, the plasma blade electrically connected to the energy source and independently activatable from the sealing plates. The plasma blade includes an insulative material on either side thereof configured to focus electrical and thermal energy to an exposed edge defined along a length of the plasma blade.

Abstract: A knife configured for use with an electrosurgical forceps having curved jaw members and a method of manufacturing the same. The knife includes a distal body having an inner side and an outer side, a first etching on the outer side of the distal body defining a distal cutting edge and a second etching on the outer side of the distal body extending along a portion of a length of the distal body to define relatively protruded and relatively recessed surfaces extending along a portion of the length of the distal body on the outer side thereof.

Abstract: A forceps includes first and second shafts each having a jaw disposed at a distal end thereof configured to rotate about a pivot to move the jaws between open and closed positions, the shafts defining a longitudinal axis therebetween. A knife deployment mechanism including a rack and pinion mechanism or a series of links is disposed within the first shaft and includes a trigger moveable along the longitudinal axis to deploy a knife between the jaws. A knife lockout is configured to move upon approximation of the first and second shafts between an engaged position preventing deployment of the knife and a disengaged position allowing deployment of the knife. A knife kickout mechanism is disposed within the first shaft in opposition to the second shaft and is configured to force the knife forward upon movement of the first and second shafts from an approximated position to a more open position.

Abstract: A surgical instrument includes a housing, a shaft extending distally from the housing, an end effector assembly disposed at a distal end of the shaft, a knife slidably disposed within the shaft, a movable handle operably coupled to the housing, a trigger operably coupled to the housing, a drive assembly operably coupled between the movable handle and the end effector assembly such that movement of the movable handle manipulates the end effector assembly, and a linkage operably coupled between the trigger and the knife such that movement of the trigger deploys the knife. In an initial position of the movable handle, a portion of a drive housing of the drive assembly intersects a path of movement of the linkage to inhibit movement of the linkage, thereby inhibiting actuation of the trigger.
