Abstract

A portable electrosurgical device (ESD) has a housing, a probe connected to the housing and a heating element connected to the probe for destroying human tissue. The heating element is detachable from the probe and/or the probe with heating element can be detachable from the housing. The user can set a drive signal'"'"'s electrical characteristics, such as operating frequency, duty cycle, peak voltage and the like for a customized drive signal formed in the ESD based on the heating element used. Memory storage allows for storage of inputted data from a keyboard, downloaded reference documents and information off the Internet from an Ethernet connector that can be displayed for reference on a screen of the ESD. Another even more compact ESD is an integral one-piece portable device having a type of pistol hand-held grip, dis-connectable probe, and a rechargeable, removable battery in the handle provides approximately 30, one-minute treatments on a single battery charge.
