ENERGY-BASED SURGICAL DEVICE AND SYSTEM FACILITATING TISSUE REMOVAL

An energy-based surgical device includes an elongated outer tube having a distal overhang, a proximal hub, a distal cutting member, and a flat spring. The distal cutting member has a U-shaped cutting edge and defines a mouth with the distal overhang extending therethrough. The flat spring includes a first portion extending distally along an exterior surface of the elongated outer tube and the distal overhang, a second portion extending from the first portion and bent over a free distal end of the distal overhang, and a third portion extending from the second portion proximally through the mouth of the distal cutting member and into the lumen of the elongated outer tube and traverses a majority of a diameter thereof. The distal cutting member and flat spring are adapted to connect to a source for electrosurgical energy for conducting bipolar energy through tissue disposed therebetween to cut tissue.
