Abstract
Problems to be SolvedSurgical operation or others excellent in operability, safety, operation efficiency and precision are realized by outputting a vertical-torsional composite vibration through conversion processing of the longitudinal vibration from an ultrasonic oscillation mechanism and reducing the displacement speed of the non-working plane in a female portion less than the speed of the working plane.Means to Solve the ProblemA configuration, comprising an ultrasonic oscillation mechanism composed of a longitudinal vibration element, a backing plate and a front plate for generating an ultrasonic vibration, a horn coupled with the ultrasonic oscillation mechanism for amplifying the vibration transmitted from said ultrasonic oscillation mechanism, a vibration conversion mechanism for converting the vibration transmitted from said ultrasonic oscillation mechanism into a composite vibration composed of a longitudinal vibration in the horn central axial direction and a torsional vibration having the horn central axis as fulcrum, and a female portion provided with a working plane and disposed at said horn tip, wherein said ultrasonic oscillation mechanism is composed of one or more…
