Abstract
An electrosurgical electrode capable of vaporization, coagulation, desiccation or cutting of tissue is disclosed. The probe has a first portion configured for tissue vaporization, and a second portion configured for tissue desiccation or coagulation. Simultaneous vaporization and desiccation may be achieved, the balance between the effects being controlled by the orientation and motions of the electrode. The electrode may have irrigation and aspiration means.
Claims38
A monopolar electrosurgical probe comprising
- a handle having a proximal end and a distal end;
- an insulated elongated member having a proximal end and a distal end, wherein the proximal end of said elongated member is affixed to the distal end of said handle;
- a single conductive electrode having a proximal end and a distal end, wherein said proximal end is assembled directly to the distal end of said elongated member;
- said conductive electrode comprising first and second conductive surfaces that intersect to form a distal edge having an included angle ranging between 20 and 110 degrees, said first conductive surface having a distal portion in which are formed a plurality of protuberances that create regions of high current density for high efficiency vaporization of tissue and said second conductive surface having a smooth convex contour adapted for coagulating tissue.
