Abstract
An electrosurgical device with an electrode having a first portion whose exterior is electrically uninsulated, a second portion whose exterior is electrically insulated, and a third portion. The device includes an elongated hollow body formed by a first member and a second member. The second member is capable of rotating relative to the first member. The hollow body has an internal cavity, a front end, a rear end, an external surface, and an electrical wire arranged within the body. The hollow body is configured to reversibly receive the third portion of the electrode at the front end of the body such that electrical contact is made between the electrode and the electrical wire and the second portion of the electrode is not surrounded by the hollow body. A first button is provided for controlling a current flow at a first level to the electrode and is arranged on the external surface. A vacuum tube is slidably engaged by the body and has an inlet generally facing the front end and adjacent the electrode. A vacuum outlet port is arranged near the rear end of the body, and the outlet port, internal cavity, and vacuum inlet are in fluid communication with each other.
