Methods of using ultrasonically powered surgical instruments with rotatable cutting implements
First Claim
1. A method of treating tissue within an aqueous environment comprising:
- introducing a cutting implement of a surgical instrument into the aqueous environment, the cutting implement having at least one cutting surface thereon and at least one ultrasonic portion thereon and being selectively rotatable within a hollow sheath between cutting positions wherein the at least one cutting surface may be exposed to tissue and an ultrasonic position wherein the ultrasonic portion may be exposed to the tissue;
rotating the cutting implement within the hollow sheath;
cutting tissue with the at least one cutting surface of the rotating cutting implement;
positioning the cutting implement in the ultrasonic position;
retaining the cutting implement in the ultrasonic position;
applying pressure to tissue with the exposed ultrasonic portion of the cutting implement; and
applying ultrasonic motion to the cutting implement.

Abstract
In one general aspect, various embodiments are directed to methods for treating tissue within an aqueous environment. Various methods may include introducing a cutting implement of a surgical instrument into the aqueous environment. The cutting implement may have at least one cutting surface thereon and at least one ultrasonic portion thereon and be selectively rotatable within a hollow sheath. The methods may include rotating or rotatably oscillating the cutting implement within the hollow sheath for tissue cutting purposes. The cutting implement may also be retained in a position wherein the ultrasonic portion of the cutting implement may be applied to tissue and then have ultrasonic motion applied thereto.
