Abstract

An electrosurgical apparatus, system, and method are disclosed. The apparatus, includes an elongate member defines a longitudinal opening. An elongate actuator member is slideably movable within the longitudinal opening. A proximal jaw member having a proximal portion is fixedly coupled to a distal end of the elongate flexible member. A distal jaw member has a proximal portion fixedly coupled to a distal end of the elongate actuator member. A first aperture is defined between the distal portion of the distal jaw member and the proximal portion of the distal jaw member. The distal jaw member is slideably movable relative to the proximal jaw member. The system includes a handle portion to receive a proximal end of the elongate actuator member of the apparatus. A method includes preparing the apparatus for surgery.

Claims
