Abstract: A surgical instrument includes a housing, energizable member, first activation switch, cable assembly, and second activation switch. The housing is operatively associated with the energizable member. The first activation switch is coupled to the energizable member and is selectively transitionable from an open condition to a closed condition. The cable assembly is coupled to the housing at a first end and includes a plug at a second, opposite end, the plug housing a second activation switch selectively transitionable from an open condition to a closed condition. The plug is adapted to connect to the source of electrosurgical energy, wherein transitioning of the first activation switch from the open condition to the closed condition transitions the second activation switch from the open condition to the closed condition such that the second activation switch communicates with the source of electrosurgical energy to initiate the supply of energy to the energizable member.

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: 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.

IPC: A61B18/14
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 bipolar electrosurgical instrument includes a housing and an elongated shaft. An end effector is coupled to a distal end of the elongated shaft. A handle assembly includes a movable handle movable relative to a fixed handle for effecting movement of the jaw members from a first position to a second position. Each jaw member is configured to connect to a source of electrosurgical energy. A switch is disposed on the fixed handle and configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a switch engaging surface disposed on the movable handle. The first position of the switch causes the relay of information to the user corresponding to a desired pressure on tissue grasped between the jaw members and the at least one subsequent position is configured to activate the source of electrosurgical energy.
