Abstract
An electrosurgical pencil for use in performing surgery on a surgical site includes a main body forming a handle grippable by user and having open front and rear ends. The pencil has a vent tube open at its forward end, and slidably mounted in the body. The tube is adjustable independently from a retracted position to various extended positions. An elongate electrode is mounted in the tube and independently slidable therein. The electrode is adjustable manually in its longitudinal direction from a retracted position to extended positions. A first conducting strip can be mounted in the vent rube in contact with the electrode. A second conducting strip can be mounted in the main body and is in sliding contact with the first strip in order to provide power to the electrode.

An electrosurgical tool for performing a surgical procedure, comprising:
- an elongated body;
- an elongated vent tube mounted in the body;
- an elongated electrode mounted in the vent tube and configured to move longitudinally relative to at least one of the vent tube or the body;
- a conducting member disposed in the body;
- and
- a connector attached to the electrode, the connector in sliding contact with the conducting member, such that the electrode and the conducting member are slidably, electrically connected to one another.
An electrosurgical tool for performing a surgical procedure, comprising:
- a main body;
- an elongated vent tube disposed in the main body, the vent tube having a wall that defines an opening through a thickness thereof;
- an elongated electrode disposed in the vent tube and configured to move longitudinally relative to at least one of the main body or the vent tube;
- a first conducting member electrically coupled to the electrode;
- and
- a second conducting member, wherein the first conducting member has a section that extends through the opening of the vent tube and into sliding contact with the second conducting member.
