    Abstract: The present disclosure is directed to a forceps having an end effector assembly including first and second jaw members. At least one of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. Each jaw member includes an electrically-conductive tissue-contacting surface adapted to connect to a source of energy to treat tissue grasped between the jaw members. A suction system is disposed proximate the first and second jaw members and is configured to apply suction to a surgical site upon activation thereof.

    Abstract: A surgical instrument includes an end effector assembly and a deployment mechanism for deploying a proximal hub associated with an energizable member between proximal and distal positions. The deployment mechanism includes a rotatable shaft, a cord including a proximal end engaged to the rotatable shaft and a distal end engaged to the proximal hub, a biasing member positioned to bias the proximal hub towards the distal position, and a gear assembly operably coupled to the rotatable shaft. The gear assembly is configured to move the proximal hub from the distal position to the proximal position against the bias of the biasing member by rotating the rotatable shaft relative to the cord to at least partially wind-up the cord about the rotatable shaft.

    Abstract: A surgical instrument includes a housing, an energizable member, a powered deployment assembly, and a cable assembly. The energizable member is configured to supply electrosurgical energy to tissue, and is movable between a storage position and a deployed position. The powered deployment assembly is configured to selectively move the energizable member between the storage position and the deployed position. The cable assembly having a cable coupled to the housing at a first end and having a plug coupled to the cable at a second, opposite end. The cable housing one or more first wires for selectively providing electrosurgical energy to the energizable member and one or more second wires for selectively providing power to the powered deployment assembly. The plug is configured to house a battery therein for powering the powered deployment assembly via the one or more second wires.
