A switch for use with an electrosurgical tool having a heatable tip connectable to a power source and a suction passage connectable to a suction source. The switch comprises a main body having a suction passage extending therethrough connectable to the suction passage of the tool. A cavity in the main body intersects the suction passage and is adapted to slidably receive a mounting post to permit slidable movement of the main body over the mounting post. The mounting post has an end protruding from the main body that is pivotally connectable to the tool. An opening extends through the mounting post that is alignable with the suction passage. In operation, the main body of the switch is manually movable between a default position in which the suction passage and the opening are misaligned to block suction and an operating position in which the suction passage and opening are aligned to permit suction. In the operating position, the main body pivots with the mounting post to permit electrical connection of the heatable tip to the power source to perform cutting or coagulating.

Switch for electrosurgical tool for performing cutting, coagulation, and suctioning

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.
