Light emitting electrosurgical scalpel

摘要

An improved electrosurgical scalpel, with light emission, for generating electrical signals intended for applications to the body of a patient via an electrosurgical electrode is provided. An electrosurgical scalpel includes a handle with a receptacle portion of a conductive member for mounting and retaining an electrode blade, a light source with a power source encapsulated within the handle and a means to direct the light emitted outwardly towards the electrode tip. Operation of a switch on the handle to an on position serves to complete a circuit, activating the light source and, thereby directing light through an opening or upper portion and out from the first end of the handle towards the distal end of the electrode blade.

主权项

1. 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; 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, anda 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; and an electrically conductive lead comprising:
a first end disposed within the housing and being coupled in electrical communication with the circuit board; anda second end extending outwardly from the housing and being configured for electrically coupling with the external electrosurgical signal generator.
