Abstract

A removable shroud for use with an electro-surgical unit pencil is disclosed where the shroud fits over a portion of the external surface of the electrosurgery unit pencil. The removable shroud includes a cylindrical shaped handpiece having an opening therein which provides means for accessing a hand switch contained on the electrosurgery unit pencil when the pencil is positioned within the shroud, a chute located alongside a bottom length of the cylindrical handpiece, and a tapered nozzle located near the distal ends of the cylindrical handpiece and the chute. The interior of the chute opens into the lumen of the cylindrical handpiece near the distal end of the chute and the proximal end of the chute extends beyond the proximal end of the cylindrical handpiece.

Claims

1. A removable shroud for use with an electro-surgical unit (ESU) pencil apparatus wherein said shroud is adaptably fitted over an external surface of said ESU pencil apparatus, said shroud comprising:

a cylindrical shaped handpiece holder having a distal end, a proximal end and a lumen located between said proximal and distal ends wherein a portion of said cylindrical handpiece is cut away to expose said lumen and thereby provide means for accessing a handswitch contained on said ESU pencil apparatus when said ESU pencil apparatus is positioned within said shroud;

a chute having a proximal end and a distal end located alongside a bottom length of said cylindrical handpiece wherein an interior of said chute opens into the lumen of said cylindrical handpiece near the distal end of said chute and the proximal end of said chute extends beyond the proximal end of said cylindrical handpiece; and

a tapered nozzle located near the distal ends of said cylindrical handpiece and said chute.

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

3. The removable shroud of claim 1 wherein said cylindrical handpiece and said chute share a common wall along the bottom length of the cylindrical handpiece and a top length of the chute.

4. The removable shroud of claim 2 further comprising an elongated nozzle having a tapered end for replacing said tapered nozzle.
