Abstract
A monopolar electrosurgical instrument includes a hollow cylindrical metallic electrode which is connected to one pole of a radio frequency generator via a first end of the electrode, and a handle connected to and partially covering the electrode. The electrode includes at least one lumen to permit liquid supply of cooling liquid to the hollow electrode, a part covered with an insulative material, and a coagulating and cutting uninsulated tip. The tip includes a round ending part, a part attached to the cutting metal blade near the round ending part, and a part non-attached to the cutting metal blade. It is useful for precisely cutting the tissue that it is previously coagulated, using a single instrument, and avoiding risk of bleeding.
