Claims20
A surgical pencil comprising:
- a handpiece having a conduit contained therein and at least one electrical contact element;
- a hollow tubular member comprised of a conducting material wherein said hollow tubular member is concentrically contained within said conduit such that it extends along an entire length of said handpiece and such that there is a space between an inner circumference of said handpiece and an outer circumference of said hollow tubular member along an entire length of said handpiece, and said at least one electrical contact element is in contact with said hollow tubular member;
- an electrode connected to said hollow tubular member;
- means for connecting an energy source to said at least one electrical contact;
- means for providing a coagulating material supply to said hollow tubular member;
- and
- means for supplying a vacuum to said space between said handpiece and said hollow tubular member.

A telescopic surgical pencil comprising:
- a handpiece having at least one electrical contact;
- a telescopic member having a conduit therein circumferentially positioned within the handpiece for adjusting a length of the telescopic member extending from the handpiece;
- a hollow tubular member comprised of a conducting material wherein said hollow tubular member is concentrically contained within said conduit such that it extends along an entire length of said handpiece and such that there is a space between an inner circumference of said telescopic member and an outer circumference of said hollow tubular member along an entire length of said handpiece, and said at least one electrical contact element is in contact with said hollow tubular member;
- an electrode connected to said hollow tubular member;
- means for connecting an energy source to said at least one electrical contact;
- means for providing a coagulating material supply to said hollow tubular member;
- and
- means for supplying a vacuum to said space between said telescopic member and said hollow tubular member.
