ABSTRACT:
A disposable aspirator assembly for use with an electrocautery handpiece is disclosed wherein the assembly removably attaches to the body of an electrocautery handpiece. The assembly is generally "T" shaped with the "base" of the T curved to extend in the general direction of the long axis of the handpiece to removably attach to vacuum tubing. In a preferred embodiment the hollow, tubular cross-member of the T is elastic and attaches by means of friction to the tip end of the electrocautery handpiece where it forms a substantially vacuum-tight fitting with the handpiece and protectively houses the electrocautery blade. Disposable vacuum tubing has a concave outer surface which mates with the convex outer surface of a cautery handpiece providing a cylindrical assembly which is easily grasped. The projection of the tip of the aspirator assembly along the electrocautery blade is adjustable. Since the assembly and the tubing are disposable, the assembly permits reuse of the electrocautery handpiece because it eliminates the need to wash or clean an integral vacuum channel housed within the handpiece following surgery.
