REMOVING TISSUE WITH ELECTROSURGICAL LOOP AND SUCTION

摘要

An electrosurgical instrument for removing tissue includes a shaft and a cutting member. The shaft extends to a distal end and defines a lumen configured to communicate with a vacuum source. The cutting member is supported at the distal end of the shaft. The cutting member is adapted to couple to an electrosurgical energy source and is configured to form an annular loop. The cutting member is selectively transitionable from a first configuration, wherein the annular loop includes a first diameter to one or more additional configurations, wherein the annular loop includes a second diameter smaller than the first diameter. The annular loop is configured to sever tissue within the annular loop.
