Abstract

Access to the internal components within an electrosurgical generator is facilitated by removing a panel from a housing of the electrosurgical generator and separating electrical connections between an internal circuit board and electrical connectors in the panel housing. A socket-defining connector member is removable from and replaceable within an insert receptacle in which it is retained in a plug-receiving receptacle in the housing panel. A
light emitter projects light supplied by an optical fiber into the plug-receiving receptacle. The non-electrical light conductors do not pick up noise created by the high voltage electrosurgical power conducted through the front panel. Spring electrical contacts facilitate making and breaking mechanical and electrical connections between the front panel and the internal components within the electrosurgical generator.
