Abstract: An endoscopic instrument is provided and includes a housing including an elongated shaft assembly extending distally therefrom. The elongated shaft assembly includes inner and outer shaft members. The inner and outer shaft members are removably coupled to the housing and the outer shaft member is movable with respect to the inner shaft member. An end effector is operably supported at the distal end of the outer shaft member and includes a pair of jaw members configured for treating tissue. A bushing operably couples to the inner and outer shaft members of the shaft assembly and selectively and releasably couples to the housing. The bushing includes one or more mechanical interfaces configured to engage one or more slots defined through the inner shaft member and one or more slots defined through the outer shaft member to release the inner and outer shaft members from the housing.

Abstract: An end effector assembly for an optical surgical instrument includes a jaw member and a plurality of optical elements positioned within a cavity of the jaw member. The jaw member has a tissue contacting surface. The jaw member has a proximal portion that is configured to secure a fiber optic cable thereto such that a distal end of the fiber optical cable extends into the cavity. The plurality of optical elements are arranged in a staircase-like manner that rises towards the tissue contacting surface as the plurality of optical elements extends distally within the cavity. The plurality of optical elements is configured to direct a beam of light exiting the fiber optic cable towards the tissue contacting surface.

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.

Abstract: An endoscopic forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and has a pair of first and second jaw members. One of the first and second jaw members is movable relative to the other jaw member from an open position, to a clamping position. One of the first and second jaw members includes one or more cam slots defined therein and configured to receive a cam member that upon movement thereof rotates the movable jaw member from the open position to the clamping position. A resilient member is operably coupled to the jaw member that includes the one or more cam slots. The resilient member is configured to provide a camming force to the cam slot and to bias the first and second jaw members in the clamping position.

Abstract: The present disclosure is directed towards a medical instrument. The medical instrument includes a housing and an end effector assembly operably connected to the housing. The end effector assembly includes first and second jaw members each having a tissue contacting surface, at least one of the first and second jaw members movable between a first, spaced-apart position and a second proximate position, wherein in the second position, the jaw members cooperate to define a cavity configured to receive tissue between the jaw members. The end effector also includes at least one light-emitting element coupled to at least one of the first and second jaw members, the at least one light-emitting element adapted to deliver light energy to tissue grasped between the first and second jaw members to treat the tissue.

Abstract: A surgical instrument includes an active electrode coupled to a source of electrosurgical energy. The active electrode includes a tissue-contacting surface on an exterior surface of the instrument such that the tissue-contacting surface of the active electrode may intimately engage tissue. A replacement electrode includes a tissue-contacting surface, and is located in an interior cavity of the instrument. A seal is formed between the active electrode and the interior cavity of the instrument such that the tissue-contacting-surface of the replacement electrode is isolated from contamination exposed to the exterior of the instrument. The active electrode is removable from the instrument to expose the tissue-contacting surface of the replacement electrode, and the replacement electrode is connectable to the source of electrosurgical energy when the active electrode is removed.
