Abstract
An electrosurgical forceps is provided. The electrosurgical forceps includes an end effector including first and second jaw members. One of the first and second jaw members is movable from an open configuration for positioning tissue between the first and second jaw members to a closed configuration for grasping tissue for subsequent electrosurgical treatment thereof. One or more cutting electrodes are positioned on the first and/or second jaw members. The cutting electrode(s) includes one or more piezo-elements that are configured to oscillate at a predetermined frequency when the cutting electrode(s) is energized to sever tissue.
Claims20
An electrosurgical forceps, comprising:
- an end effector including first and second jaw members, at least one of the first and second jaw members movable from an open configuration for positioning tissue between the first and second jaw members to a closed configuration for grasping tissue for subsequent electrosurgical treatment thereof;
- and
- at least one cutting electrode positioned on at least one of the first and second jaw members, the at least one cutting electrode including at least one piezo-element that is configured to oscillate at a predetermined frequency when the at least one cutting electrode is energized to sever tissue.
An electrosurgical forceps, comprising:
- a housing having a shaft extending distally therefrom and defining a longitudinal axis therethrough;
- an end effector including first and second jaw members, at least one of the first and second jaw members movable from an open configuration for positioning tissue between the first and second jaw members to a closed configuration for grasping tissue for subsequent electro surgical treatment thereof;
- and
- at least one cutting electrode positioned on at least one of the first and second jaw members, the at least one cutting electrode configured to oscillate at a predetermined frequency and in at least one direction with respect to the longitudinal axis when the at least one cutting electrode is energized to sever tissue.
