Abstract

A removable shroud for use with an electro-surgical unit pencil. The removable shroud includes a handpiece with a lumen therein; an elongated load-bearing support bearing a receiving surface on a top of the handpiece for cradling the electro-surgical unit pencil thereon; and a tapered nozzle, adapted to hold a distal end of the electro-surgical unit pencil therein when the pencil rests on the receiving surface, located at a distal end of the handpiece and having the lumen open into an interior of the tapered nozzle.

Claims

1. A removable shroud adapted to receive an electro-surgical unit pencil, the shroud comprising:

a handpiece having a distal end and a proximal end with a lumen therebetween and an elongated load-bearing support bearing a receiving surface on a top of said handpiece for cradling the electro-surgical unit pencil thereon; and

a tapered nozzle, adapted to hold a distal end of the electro-surgical unit pencil therein when the pencil rests on the receiving surface, located at a distal end of the handpiece wherein said lumen opens into an interior of said tapered nozzle.

2. The removable shroud of claim 1 further comprising means for releasably holding said electro-surgical unit pencil mounted to the elongated support for releasably retaining the electro-surgical unit pencil on the receiving surface.

3. The removable shroud of claim 1 wherein said tapered nozzle is retractable.

4. The removable shroud of claim 3 wherein said tapered nozzle includes coupling means for extending and holding said retractable nozzle in a first position when a retractable electro-surgical tip of said electro-surgical unit pencil is extended, and for retracting and holding said tapered nozzle in a second position when said retractable electro-surgical tip is retracted.
