Abstract

A blunt tipped trocar which uses ultrasonic energy in the form of vibrations to assist a user in penetrating tissue. In one embodiment of the invention, a feedback mechanism is provided which senses a variation in load on the trocar tip and adjusts the ultrasonic energy level of the vibrating tip in accordance with the load condition. Another embodiment of the invention provides a trocar with a self-contained ultrasonic generator.
