    摘要: An apparatus and method for ultrasonically forming a surgical suture tip from a length of unfinished surgical suture material. The apparatus includes a first tipping die having a first face for contacting a portion of the length of unfinished surgical suture material. A second tipping die having a second face is also provided. The first and second die also having extending therefrom a first member and a second member. The first and second dies cooperate with the first and second members to form a length of suture. At least one mechanical actuator is provided for moving the first face of the first tipping die and the third face of the first member toward the second face of the second tipping die and the fourth face of the second member. A second actuator vibrates at least one of the first and second tipping dies at an ultrasonic frequency of about 15 KHz to about 70 KHz. The method of ultrasonically forming a suture tip comprises the positioning a surgical suture between the first, second, third and fourth faces of the tipping apparatus then vibrating the dies at an appropriate frequency.
