Extendable electrocautery surgery apparatus and method

摘要

An improved electrocautery method and instrument is configured to accept attachable extension units for effectively extending the utility of the instrument into deep surgical sites. Interlock features enable the instrument to be safely configured to any desired length for use as a vacuum probe and as a self-cleanable electrocautery or electro-surgical instrument under convenient manual controls including a slide element and control buttons and interlock switch positioned on the instrument.
