Abstract:
1. An electrosurgical midline clamping scissors for simultaneous mechanical cutting and electrocoagulating of tissue or blood vessels, comprising: a pair of arms including first and second substantially elongate arms, each of the arms having a proximal end and a distal end; a pivot joint connecting the first and second arms medially, the pivot joint defining a common axis for pivoting movement of the first and second arms with respect to each other; a finger loop disposed at the proximal end of each of the arms, the finger loop being adapted for receiving thumbs and fingers of a user for manipulating the elongate arms; a jaw connected to the distal end of each of the arms, each of the jaws having an elongate midline cutting section for cutting target tissue and an elongate, serrated grasping section disposed on both lateral sides of the cutting section, the jaws being movable between a spaced, open position and a closed position by pivotal movement of the first and second arms, the grasping sections being adapted for holding and clamping the target tissue during use, wherein the jaws comprise; a locking mechanism disposed between the finger loops of the elongate arms; a generator for producing an electric current, each of the arms having a terminal, the generator having lines to each of the terminals; and an electrical conductor disposed inside each of the arms, each of the electrical conductors extending from the terminals through the arms to the respective jaws and being disposed on both lateral sides of the cutting section; wherein closing of the jaws about the target tissue completes an electric circuit and simultaneously clamps, cuts and electrocoagulates the target tissue.
