Abstract
An ultrapolar telescopic electrosurgery pencil/handpiece with or without smoke evacuation that is capable of cutting with a sharp non-conductive cutting end of an electrosurgery blade and cutting and coagulating with activation of active and return contacts both contained on each side of the electrosurgery blade.
Claims25
An ultrapolar telescopic electrosurgery pencil comprising:
- a handpiece member having a first end and a second end;
- a hollow telescopic member having a first end and a second end wherein at least a portion of the hollow telescopic member is concentrically positioned within the first end of the handpiece member;
- an electrosurgery blade having both an active contact and a return contact positioned within the first end of the hollow telescopic member such that a passageway exists around the electrosurgery blade that is in communication with an area outside the first end of the hollow telescopic member;
- a first hollow conductive tubular member in contact with the active contact f the electrosurgery blade and contained within the hollow telescopic member;
- a first solid conductive cylindrical member in contact with the return contact of the electrosurgery blade and contained within the hollow telescopic member;
- a second hollow conductive tubular member contained within the handpiece member such that at least a portion of the first solid cylindrical member is contained within at least a portion of the second hollow conductive tubular member;
- and
- a second solid conductive cylindrical member contained within the handpiece member such that at least a portion of the second solid conductive cylindrical member is contained within at least a portion of the first hollow conductive tubular member.
