摘要： An endoscopic forceps for treating tissue includes a housing having a shaft affixed thereto which has first and second jaw members attached to a distal end thereof. The forceps also includes an actuator for moving jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members is adapted to connect to a source of electrosurgical energy such that the jaw members are selectively capable of operating in a bipolar mode which enables the jaw members to conduct bipolar energy through tissue held therebetween to treat tissue. The forceps also includes a monopolar element housed within the first jaw member and integrally associated with the knife. The monopolar element is selectively movable from a first position within the first jaw member to a second position distal to the first jaw member. The monopolar element is adapted to connect to the source of electrosurgical energy such that the monopolar element is selectively activateable independent of the bipolar mode.

摘要： A debrider apparatus is disclosed. The debrider includes a first tubular member that is adapted to connect to a first potential of an electrosurgical generator. A second tubular member is at least partially disposed within the first tubular member and is adapted to connect to a second potential of the electrosurgical generator. At least one tubular member is selectively movable relative to the other. A first set of teeth is disposed around at least a portion of a distal periphery of the first tubular member. A second set of teeth is disposed around at least a portion of a distal periphery of the second tubular member. At least one switch is operably coupled to at least one of the tubular members and activates movement of one tubular member and supplies respective electrical potentials to the tubular members.

摘要： A method of manufacturing a jaw member of an end effector assembly for use with an electrosurgical instrument is disclosed that includes the steps of providing an electrically conductive tissue engaging plate and a jaw support; covering one side of the electrically conductive tissue engaging plate with an electrically insulative, thermally non-degrading coating; placing and securing the electrically conductive tissue engaging plate and the jaw support into a jaw mold; and introducing a liquid substance into the jaw mold and allowing the liquid substance to cure around the electrically conductive tissue engaging plate and the jaw support. Alternatively, the method includes the steps of: providing an electrically conductive tissue engaging plate and a jaw support; covering one side of the electrically conductive tissue engaging plate with an electrically insulative, thermally non-degrading coating; and securing the side of the electrically conductive tissue engaging plate onto the jaw support with an adhesive.
