Methods of using ultrasonically powered surgical instruments with rotatable cutting implements

摘要

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.
