Manually extendable electrocautery surgical apparatus
First Claim
1. A manually extendable electrocautery surgical apparatus, comprising:
- a) an elongated, non-conductive main housing having a cord end and a distal end, with an elongated aperture extending into the main housing from the distal end;
b) an elongated electrode housing having an internal aperture extending therethrough, with an electrically conductive material surrounding the internal aperture, and an insulating sleeve surrounding the electrically conductive material, the electrically conductive material surrounding the internal aperture receiving a portion of an electrode therein, and the insulating sleeve sized to be slidably received at least partially within the elongated aperture extending into the main housing from the distal end;
c) an elongated, electrically conductive post extending within the elongated aperture in the main housing, the post sized to provide electrical contact with the electrically conductive material within the internal aperture of the slidably received, elongated electrode housing; and
d) an actuating means for selectively actuating an electrical current passing through an electrical cord from remote electrical supply means, through the electrically conductive post to the electrode;
wherein the elongated electrode housing is slidably positioned in relation to the main housing, to adjustably position the electrode to a desired depth suitable for selectively cauterizing and cutting a patient'"'"'s tissue during an operation.

Abstract
The manually extendable electrocautery surgical apparatus slidably receives an electrode housing apparatus within an elongated aperture within a main housing. The electrode housing is slidably received upon a conductive post which provides an electrical connection to the electrode housing from a remote electrical supply source. An insulating outer layer surrounds the electrode housing apparatus, and the insulating outer layer is slidably received within the cylindrical cavity in the main housing. The electrode is inserted into the distal end of the electrode housing, and the electrode housing is adjustably positioned in relation to the main housing, to obtain the desired length during surgery. The main housing includes at least one actuation member for selectively controlling the flow of current to the electrode housing. The electrical current may further be adjusted to perform cutting or coagulating routines.
