Abstract: A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.

Abstract: A surgical instrument includes a housing and an elongated shaft operably coupled to an actuating mechanism moveable between an actuated position and an unactuated position. An end effector includes a pair of opposing first and second jaw members and is adapted to connect to a source of electrosurgical energy. A switch is moveable between an activated position to initiate delivery of electrosurgical energy to the end effector and a deactivated position to terminate delivery of electrosurgical energy to the end effector. A switch activation member is configured to move the switch between an activated position and a deactivated position. A switch control member is configured to maintain the switch in the activated position during at least partial movement of the actuating mechanism from the actuated position to the unactuated position.

Abstract: An electrosurgical instrument includes a housing including an elongated shaft. A stationary actuation member is axially disposed within the elongated shaft and includes a cam pin. An actuating mechanism is operably coupled to the elongated shaft and is moveable relative to the housing to selectively cause movement of the elongated shaft. An end effector includes a pair of opposing first and second jaw members operably coupled about a common pivot. One or both of the jaw members includes a camming slot configured to engage the cam pin. Each jaw member includes an electrically conductive tissue sealing surface adapted to connect to a source of electrosurgical energy. A knife blade is supported in the elongated shaft and moveable in a longitudinal direction to cut tissue disposed between the jaw members. A switch is configured to be engaged by the actuating mechanism to initiate delivery of electrosurgical energy to tissue.

Abstract: A forceps includes an end effector assembly including first and second jaw members. One or both of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One or both of the jaw members is configured to conduct energy between the jaw members and through tissue grasped therebetween to treat tissue. An insulative tubular member is movable relative to the end effector assembly between a retracted position, wherein the insulative tubular member is positioned proximally of the end effector assembly, and an extended position, wherein the insulative tubular member is disposed about the end effector assembly. A monopolar member is configured to apply energy to tissue to treat tissue when the insulative tubular member is disposed in the extended position.

Abstract: A system and method for wirelessly powering an electrosurgical device using a generator to generate a radio frequency (RF) energy field. A switch on the electrosurgical device sends a wireless signal to the generator, where the generator allows a current to pass through an inductive coil to generate the RF energy field. The RF energy field induces a current to flow across an inductive coil within the electrosurgical device. The current flow is then processed through a RF conditioning circuit and outputted to the end effector assembly of the device.

Abstract: A surgical instrument includes an end effector assembly and a switch assembly. The end effector assembly includes a monopolar assembly and a bipolar assembly. The switch assembly includes first and second bipolar inputs, first and second bipolar outputs, a monopolar input, and a monopolar output. The switch assembly is transitionable between a first condition, wherein the first and second bipolar inputs are coupled to the first and second bipolar outputs, respectively, for supplying energy to the bipolar assembly, and a second condition, wherein the monopolar input and the monopolar output are coupled to one another for supplying energy to the monopolar assembly.
