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

摘要

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.
