Attorney, Agent or FirmInternational ClassA61F 009/00AbstractA method is provided for preventing damage to tissue during microsurgery. The method involves the use of a heat sink in the form of a cylindrical shield which is inserted within an incision prior to the use of an ultrasonic cutting tool. The heat generated by the cutting tool is absorbed by the shield rather than the surrounding tissue, thereby minimizing or eliminating damage to the tissue adjacent the cutting tool. The incision through which the cutting tool extends during an operation accordingly tends to remain in its original state rather than widening due to the effects of heat damage. | |
