    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 energy system includes a first and second surgical instruments and a generator including a universal interface. The first surgical instrument includes a first instrument connector having one or more instrument couplers disposed in a first instrument coupler configuration. The second surgical instrument includes a second instrument connector having one or more instrument couplers disposed in a second instrument coupler configuration. The first and second instrument coupler configurations are different. The generator includes a universal interface including generator couplers arranged to provide generator coupler configurations at the universal interface. Each generator coupler configuration accommodates one of the first and second instrument coupler configurations in order to electronically couple the generator to a respective one of the first and second surgical instruments.

    IPC: A61B17/29

    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: A plasma instrument includes an elongated body defining a lumen therethrough, the lumen being in fluid communication with an ionizable media source; and a plasma applicator coupled to a distal portion of the elongated body. The plasma applicator includes: an active electrode configured to couple to an active terminal of a generator; and a corona electrode configured to couple to a return terminal of a generator. The plasma instrument also includes a switching element coupled to the corona electrode, the switching element configured to control at least one of resistivity or connectivity of the corona electrode to a generator.

    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.
