  • ULTRASONIC DEVICE FOR CUTTING AND COAGULATING
    Publication number: 20150327882
    Abstract: An ultrasonic assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The balanced blade provides a rounded distal end and concave edges to promote fine dissection and cutting in a variety of surgical procedures. The blade is curved for improved visibility at the blade tip and is designed to provide a multitude of tissue effects: coagulation, cutting, dissection, spot coagulation, tip penetration and tip scoring. The assembly features hand activation configured to provide an ergonomical grip and operation for the surgeon. The assembly further features user selectable blade rotation. A finger switch is placed in the range of the natural axial motion of the user's index finger, whether gripping the surgical instrument right-handed or left handed.
