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