COAGULATOR WITH GAMMA RAY DETECTOR

摘要

A surgical coagulator includes a radiation detecting sensor adjustably positioned proximate an electrode of the coagulator, and a controller for receiving and processing electrical signals from the detecting element. The controller operates to control an audio tone generator to emit a tone of higher intensity as the surgeon moves the coagulator closer to radioactively tagged malignant tissue of a patient, and of lower intensity as the coagulator moves away from the tissue, thereby pennitting the surgeon to accurately locate and remove the malignant tissue.
