Abstract
An electrosurgical device is described. The device can include a housing, a channel, and an actuator. The channel can comprise an electrode forming a tip. The actuator can be mechanically coupled to the electrode and the housing. The actuator can be configured to move between a first position and a second position and can be further configured to transition the tip from a retracted position when the actuator is at the first position to an extended position when the actuator is at the second position. A movement of the actuator from the first position to the second position can close an electrical circuit comprising the electrode and a source of electrical energy to generate a flow of current through the electrode for heating the tip to an elevated temperature suitable for cauterizing tissue.
