Abstract:
A method of performing a procedure on a meniscus, via an ultrasonic surgical tool. The ultrasonic tool includes a probe capable of transmitting ultrasonic vibration from a proximal end toward a front end. The probe includes a bent portion that is inclined with respect to a longitudinal axis of the probe, and a procedure portion that is disposed at the front end of the probe and has a plurality of cutting surfaces. The method includes: inserting the probe in a body; moving the probe through a space in between the femur and the tibia to position the procedure portion adjacent to the horizontal rupture in the meniscus; positioning a cutting surface of the procedure portion on a posterior portion of the meniscus; and resecting the horizontal rupture along an inclination of the meniscus to form an inclined resection plane.
