摘要： A multipurpose electrosurgical device is configurable in a bipolar mode and a monopolar mode using a three-conductor electrical input. The device includes a switching mechanism that provides signals corresponding with a first function and a second function in a monopolar mode. The switching mechanism also provides a signal corresponding with a third function in a bipolar mode.

摘要： An electrode assembly for an electrosurgical instrument includes a housing having an active electrical connector and a return electrical connector configured to operably engage a distal end of an electrosurgical instrument shaft, the housing encapsulating an elongated return electrode and a pair of insulative tubes configured to house a wire-like active electrode. The elongated return electrode includes a clevis at a distal end thereof and operably engages to the return electrical connector at a proximal end thereof. The wire-like active electrode operably engages at one end to the active electrical connector. A donut-like insulator is operably engaged to the clevis of the elongated return electrode and is configured to support the wire-like active electrode therearound. A tensioning mechanism is configured to operably engage an opposite end of the wire-like electrode and tension the wire-like active electrode about the donut-like insulator during assembly.

摘要： An arthroscopy system includes both a motorized handpiece and a detachable probe. The motorized handpiece includes a rotating driver which is configured to engage a rotatable drive coupling within a hub of the probe. The probe has a shaft with an articulating distal region, and the rotatable drive coupling is configured to convert the rotary motion of the rotating driver to an articulating motion within the articulating region of the probe.

摘要： An end effector assembly for an electrosurgical device includes first and second jaw members movable between spaced-apart and approximated positions. The jaw members include tissue-contacting surfaces that define a tissue grasping area. One of the jaw members includes an electrically-insulating body, an interior electrode, and an exterior electrode. The interior electrode is positioned interiorly of outer bounds of the tissue grasping area. A portion of the interior electrode forms part of the tissue-contacting surface. The exterior electrode is positioned exteriorly of the outer bounds of the tissue grasping area. At least one portion of the exterior electrode: extends along the outer back surface of the body, is disposed within the body, and is positioned adjacent the outer bounds of the tissue grasping area. The interior and exterior electrodes are configured to conduct energy through tissue grasped within the tissue grasping area to seal tissue.

摘要： A forceps includes an end effector assembly including first and second jaw members. One or both of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One or both of the jaw members is configured to conduct energy between the jaw members and through tissue grasped therebetween to treat tissue. An insulative tubular member is movable relative to the end effector assembly between a retracted position, wherein the insulative tubular member is positioned proximally of the end effector assembly, and an extended position, wherein the insulative tubular member is disposed about the end effector assembly. A monopolar member is configured to apply energy to tissue to treat tissue when the insulative tubular member is disposed in the extended position.

摘要： A surgical cauterizer includes an elongate body member having a tapered distal-end portion terminating at an apex. A cauterizing tip extends from the apex. A hollow passageway is formed in the interior of the elongate body member. Formed in the tapered distal-end portion of the elongate body member is at least one smoke intake port for providing a smoke evacuation pathway between a region proximate the cauterizing tip and the hollow passageway within the elongate body member. A tube connected to an outlet of the hollow passageway may provide a vacuum for evacuating the smoke generated by cauterization. In an embodiment, the elongate body member may include a first and second arms that define a forceps operable between an open position and a closed position.
