In general, systems, methods, and devices for electrosurgical devices with monopolar and bipolar functionality are provided. In an exemplary embodiment, a surgical device can have bipolar functionality, in which tissue engaged by the device is treated in a bipolar energy delivery mode, and can have monopolar functionality in which tissue engaged by the device is treated in a monopolar energy delivery mode.

Electrosurgical devices with monopolar and bipolar functionality

An electrosurgical electrode comprises an elongated body having a cross-sectional area and longitudinal side edges forming longitudinal cutting edges adapted for electrosurgical dissection along a plane. The body has a configuration, wherein: the thickness of the side edge is greater than 0.01&#x2033;, forming two or more cutting edges, and the cross-sectional area-to-number of cutting edges ratio is less than or equal to 0.0004 inper cutting edge; the thickness of the side edge is less than or equal to 0.01&#x2033;, forming only one cutting edge, and the cross-sectional area-to-number of cutting edges ratio is less than or equal to 0.000150 inper cutting edge; or the thickness of a first side edge is greater than 0.01&#x2033; and the thickness of a second side edge is less than or equal to 0.01&#x2033;, and the cross-sectional area-to-number of cutting edges ratio is less than or equal to 0.001 per cutting edge.

An electrode tip for use in performing electro surgical operative procedures to concentrate electrical energy communicated to the patient tissue is disclosed. The electrode tip includes a main body that can receive electrical energy from an electrosurgical generator. The main body includes a working surface defining a flash edge. The working surface communicates the electrical energy to patient tissue during an operative procedure. The flash edge concentrates the electrical energy as it is communicated to the patient tissue. The concentration of the electrical energy from the flash edge reduces excessive tissue damage surrounding an incision site and improves the efficiency of the electrode tip.
