Abstract
An improved electrosurgical scalpel, with fume evacuation, for generating electrical signals intended for applications to the body of a patient via an electrosurgical electrode is provided that includes a channel to evacuate fumes generated. An electrosurgical scalpel includes a handle with a receptacle portion of a conductive hollow member for mounting and retaining an electrode blade and evacuating fumes, an optional light source with a power source that may be encapsulated within the handle and a vacuum port for applying a vacuum source to draw fumes away from the electrode tip through the chanel. Operation of a slide on the handle serves to retract or extend the electrode blade, and direct fume evacuation.
Claims15
An electrosurgical instrument for selectively providing electrical energy to an electrode blade for cutting and coagulation, comprising:
- an elongate housing;
- a reduced neck portion at a first end of the housing, the neck portion being configured to retain an electrode blade extending outwardly therefrom, and the neck portion further including a tubular pathway to which a vacuum is applied to draw away fumes;
- a light source disposed within an interior of the housing;
- a light power source encapsulated within the interior of the housing;
- plural user-selectable switches disposed at least in part at an exterior of the housing, wherein:
- a first switch of the plural switches is configured, when actuated, to establish an electrically-conductive pathway between a retained electrode blade and an external electrosurgical signal generator, and
- a second switch of the plural switches is coupled in electrical communication with each of the light source and the light power source, wherein the second switch is configured, when actuated, to establish an electrically-conductive pathway between the light power source and the light source;
- a circuit board disposed within the housing and directly underlying at least one of the plural user-selectable switches, the circuit board further constituting a portion of the electrically-conductive pathway between the electrode blade and the external electrosurgical signal generator;
- a conductor including:
- a first end disposed within the housing and being coupled in electrical communication with the circuit board;
- and
- a second end extending outwardly from the housing and being configured for electrically coupling with the external electrosurgical signal generator;
- wherein either or both of the cutting signal and the coagulating signal comprises one of a radio frequency signal or a high-frequency electrical signal;
- and
- an electrode slide control lever, wherein the slide control is configured to:
- allow extension of the tubular pathway and maintain an electrically-conductive pathway between the electrode blade and an external electrosurgical signal generator.
