ELECTROCAUTERY SYSTEM, PROVIDED WITH SAFE LIGHTING DURING OPERATIONAL USE

摘要

A cautery tool is provided with a compact, lightweight, user-directable lighting facility that can be powered by either a shared external power source from which a power flow is shared continuously with the cautery function, by a supplemental self-contained power cell that may be recharged by a portion of the external power for use independently of the cautery function, or by sharing of a self-contained power cell by the cautery and the lighting functions. Waste heat generated during exercise of the lighting function is continuously removed from a light-emitting element by electrical conductors also serving as heat transfer conduits.
