An energy-based surgical device, comprising: an elongated outer tube defining a distal end portion, a proximal end portion, and a lumen extending longitudinally therethrough, the elongated outer tube including a distal overhang extending distally therefrom; a proximal hub disposed at the proximal end portion of the elongated outer tube; a distal cutting member disposed at the distal end of the elongated outer tube, the distal cutting member having a U-shaped cutting edge and defining a mouth, wherein the distal overhang extends through the mouth; the device further comprising: a flat spring aligned with the distal overhang, the flat spring including 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, the third portion of the flat spring traversing a majority of a diameter of the lumen of the elongated outer tube, wherein the distal cutting member and the flat spring are adapted to connect to a source for electrosurgical energy for conducting bipolar energy through tissue disposed therebetween to cut tissue. an elongated outer tube defining a distal end portion, a proximal end portion, and a lumen extending longitudinally therethrough, the elongated outer tube including a distal overhang extending distally therefrom; a proximal hub disposed at the proximal end portion of the elongated outer tube; a distal cutting member disposed at the distal end of the elongated outer tube, the distal cutting member having a U-shaped cutting edge and defining a mouth, wherein the distal overhang extends through the mouth; the device further comprising: a flat spring aligned with the distal overhang, the flat spring including 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, the third portion of the flat spring traversing a majority of a diameter of the lumen of the elongated outer tube, wherein the distal cutting member and the flat spring are adapted to connect to a source for electrosurgical energy for conducting bipolar energy through tissue disposed therebetween to cut tissue. a flat spring aligned with the distal overhang, the flat spring including 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, the third portion of the flat spring traversing a majority of a diameter of the lumen of the elongated outer tube, wherein the distal cutting member and the flat spring are adapted to connect to a source for electrosurgical energy for conducting bipolar energy through tissue disposed therebetween to cut tissue.
