  • Patent number: 11707315
    Abstract: A surgical instrument includes a housing, an energizable member, and a deployment mechanism. The energizable member is movable relative to the housing between a storage position and a deployed position. The deployment mechanism includes a first actuator member movable relative to the housing from a first un-actuated position to a first actuated position to move the energizable member from the storage position to the deployed position and a second actuator member movable relative to the housing from a second un-actuated position to a second actuated position to move the energizable member from the deployed position to the storage position. Movement of the first actuator member from the first un-actuated position to the first actuated position effects movement of the second actuator member from the second actuated position to the second un-actuated position and vice versa.

  • Patent number: 11622782
    Abstract: An endoscopic forceps includes an elongate shaft defining an instrument axis. An end effector includes first and second jaw members each supporting an opposed sealing surface for clamping tissue. At least one of the jaw members is movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue. A cutting instrument includes a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members. The reciprocating blade contacts an undersurface of at least one of the jaw members when the jaw members are in the second configuration to define a gap distance between the sealing surfaces. A handle adjacent the proximal end of the elongate shaft is operable to induce motion in the jaw members, and an actuator is operable to selectively translate the reciprocating blade.
