ABSTRACT:
A compact, self-contained lighting system is attachable to a surgical tool to enable a user to selectively direct light at a site where the tool is to be applied. The system has a power unit that may contain rechargeable power cells, a malleable electrical connection element, and a light-emitting element powered thereby to emit high intensity white light, preferably from an LED. The system ensures against tissue damage due to inadvertent overheating by continuously removing byproduct heat from the light-emitting element, via the connection element, to the power unit with portions of each of these components serving as respective heat sinks and/or as thermal conduits to facilitate this process. The removed heat is dissipated to the ambient atmosphere, the surgical tool and even the user, and permits safe prolonged operations in confined regions of a patient's body.
