ABSTRACT:
A disposable electrosurgical knife handle and blade is provided with a built-in warning light positioned on the top of the handle in the surgeon's line of vision during surgical procedures in order to warn, instantly, of unwanted surges in the electrical system which could bring about tissue damage. Because of the arrangement, the surgeon may remove immediately the blade or other cutting instrument fitted into the handle from the surgical site.
