摘要： Over the years, a variety of different types of non-ultrasonically powered cutters and shaving devices for performing surgical procedures have been developed. Some of these devices employ a rotary cutting instrument and other devices employ a reciprocating cutting member. For example, shavers are widely used in arthroscopic surgery. These devices generally consist of a power supply, a handpiece, and a single-use end effector. The end effector commonly has an inner and outer tube. The inner tube rotates relative to the outer tube and will cut tissue with its sharpened edges. The inner tube can rotate continuously or oscillate. In addition, such device may employ a suction channel that travels through the interior of the inner tube. For example, U.S. Pat. No. 4,850,354 to McGurk-Burleson, et al., discloses a non-ultrasonically powered surgical cutting instrument that comprises a rotary cutter for cutting material with a shearing action. It employs an inner cutting member which is rotatable within an outer tube.

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 and blade and sheath mounting arrangements are disclosed 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.
