Abstract
Disclosed is a ultrasonic scalpel blade with a hook and having flat, non-sharpened, relatively dull edges to improve ultrasonic coupling to adjacent tissue and afford exceptional coagulation and hemostasis. The blade with hook is particularly useful for cutting loose, unsupported tissue by grasping the tissue with the hook portion and tensioning it while cutting. The blade affords improved coagulation and hemostasis in loose, unsupported tissue, while simultaneously providing an improved cutting action.
