ABSTRACT:
A novel electrocutting/coagulating instrument is provided herein. The instrument includes a handle having a forward end and a rear end. A suction tube is secured to the handle and is adapted to be connected only to a source of suction. The suction tube has a forward end and a rear end, the rear end being connected to the handle, and also being connected to the source of suction, and the forward end of the tube projecting beyond the forward end of the handle. A manually-controllable, electrically-actuated cutting/coagulating blade electrode is operatively connected to the handle, a portion of the cutting/coagulating blade electrode projecting beyond the forward end of the handle. A lead is securely connected to the blade electrode and is adapted to be connected from a source of electricity to the cutting/coagulating blade electrode. A switch is provided to actuate the cutting/coagulating blade electrode, so that the suction tube provides a suction surrounding, and in close proximity to all portions of the cutting/coagulating blade electrode. A connector is provided which has a leg and a pair of arms, the rear end of the suction tube being connected to one arm of the connector, the other arm of the connector being connected to a separate suction handle, and the leg of the connector being connected to a source of suction.
