Abstract
IT has been remarked1 that extended injury was caused to the brain of monkeys beyond the point of a needle electrode when using high-frequency current for surgical purposes. If the needle were of a ferrous material, such as steel, or a ferrous alloy, this may be expected, and is in accordance with our research experience over many years in experimental work on instruments for electrosurgical techniques, which involve the use of high-frequency currents, particularly for ophthalmic surgery using the Safar technique.
