    摘要: In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a handpiece housing that rotatably supports an ultrasonic transducer assembly therein that may be selectively rotated by a motor housed therein. Various forms of blades are disclosed for attachment to the ultrasonic transducer assembly such that the blade may be selectively rotatable within a hollow outer sheath. The hollow outer sheath has at least one opening therein through which the blade tip may be exposed to tissue. Vacuum may be applied to the cutting implement or through the outer sheath to draw tissue through the opening(s) in the sheath and into contact with a portion of the blade.
