ULTRASOUND MEDICAL INSTRUMENT HAVING A MEDICAL ULTRASONIC BLADE

摘要

An ultrasound medical instrument includes a medical ultrasonic blade having a proximal blade portion and a distal blade portion. The distal blade portion bends more easily than does the proximal blade portion. A user-actuated articulated sheath surrounds a portion of the medical ultrasonic blade. The distal blade portion includes a distal end portion adapted to contact and ultrasonically treat patient tissue.
