Apparatus for implantation and extraction of osteal prostheses |
摘要 |
Apparatus particularly suited for implantation and/or extraction of osteal prostheses, comprising an ultrasonic power generator, regulator means for regulating the ultrasonic power generator in accordance with a predetermined algorithm, at least one transducer connected to the output line for converting said electrical energy to a linear mechanical motion, an acoustic transformer for increasing or decreasing peak-to-peak motion of the transducer and means for connecting the acoustic transformer to a surgical tool or a prosthetic device. The system suitably comprises a pair of transducers, one operating at each of 20 KHz and 40 KHz frequencies. Novel adapters for the four major types of osteal prosthesis are also provided.
