An electrosurgical loop comprising an insulated shaft with an electrical contact at its proximate end and a pair of extending insulated prongs at its distal end. The extending prongs are configured to give the loop a 'Y' shape and each end of a thin wire are connected to each prong to provide a wire loop. Disposed over the shaft in longitudinal sliding engagement is a depth gauge comprising a clasp, a longitudinal intermediate portion, and a transverse cross bar. The clasp may be retrofit to an existing electrosurgical loop and permits the removal of the depth gauge from the loop, if desired. The transverse cross bar is wider than the breadth of the wire loop and has a transverse slot oriented in the same plane as the wire loop through which the wire loop passes as the depth gauge is adjusted for various cutting depths. Disposed on the insulated shaft are markings serving as depth indicators to which the depth gauge may be moved slidably to effect cut depth control for the loop. The loop may be constructed by punching a series of shaft blanks from a conductive metal stock, and rolling the electrical contact prior to applying the insulation. Also, prior to applying the insulation, the wire loop can be connected to the shaft blank to maintain the flow of electrical current through the shaft into the wire loop.

Electrosurgical loop with a depth gauge

An electrosurgical unit which combines an electrosurgical power generator and a filtered smoke removal system into a single compact instrument comprising an electrosurgical generator module and a smoke removal module. The electrosurgical generator module is designed specifically to accommodate an electrosurgical tool during LEEP or LLETZ procedures. The electrosurgical generator module provides power to the electrosurgical tool at a predetermined level. The smoke removal module removes and filters smoke from the site of the electrosurgery. A switching circuitry activates the smoke removal module substantially simultaneous to the activation of the electrosurgical tool so that the smoke removal module is activated automatically whenever the electrosurgical tool is activated. The switching circuitry also delays the deactivation of the smoke removal module for a predetermined amount of time after the electrosurgical tool has been deactivated. The electrosurgical tool alternatively can be connected, concentrically or in parallel, to a smoke evacuation tube in communication with the smoke removal module.
