Abstract
An electrosurgical tool for use with a power source and a suction source includes a handle for gripping by the user and an electrically heatable tip extending from the handle that is selectively electrically connectable to the power source. A suction passage is formed in the handle and is connectable to the suction source. A manually actuatable switch on the body is movable between a default position in which the tip is not electrically connected to the power source and the suction passage is blocked, a cutting position in which the tip is electrically connected to the power source and heated to perform cutting and a coagulating position in which the tip is electrically connected to the power source and heated to perform coagulation. Movement of the switch to each of the cutting and coagulating positions automatically communicates the suction passage with the suction source. The device of the present invention permits electrical cautery (cutting or coagulation) and suction to occur with a single motion of the switch thereby simplifying operation and manipulation of the tool by a surgeon.
