Ultrasonic orthopedic surgical device with compound ultrasound vibration
First Claim
1. An orthopedic surgical device with compound ultrasound vibration comprising a handpiece having an outer casing, a surgical cutter fixed on the anterior top of the handpiece, and an ultrasound signal generator, wherein, inside the outer casing of said handpiece, there are provided:
- an ultrasound transducer for transforming the ultrasound signals from said ultrasound signal generator into ultrasound mechanical waves;
a horn for amplifying vibration amplitude of the ultrasound mechanical waves generated from said transducer and then transmitting the amplified ultrasound mechanical waves to said surgical cutter to provide longitudinal vibration of the surgical cutter;
a driving motor fixed in the back end of said handpiece for driving said ultrasound transducer and horn to provide the movements of swing and rotation; and
an adapter provided between the said driving motor and said transducer for supplying ultrasonic electrical signals generated by said ultrasound signal generator to said ultrasound transducer.

Abstract
An orthopedic surgical device with compound ultrasound vibration that comprises a handpiece, a surgical cutter fixed on the anterior top of the handpiece, and an ultrasound signal generator. Inside the outer casing of said handpiece, there are provided: an ultrasound transducer for transforming the ultrasound signals from said ultrasound signal generator into ultrasound mechanical waves; a horn (or amplitude transformer) for amplifying vibration amplitude of ultrasound mechanical waves generated from said transducer and then transmitting the amplified ultrasound mechanical waves to said surgical cutter to lead to longitudinal vibration of the surgical cutter; a driving motor fixed in the back end of said handpiece for driving said ultrasound transducer and horn to accomplish the movement of swing and rotation; an adapter provided between said driving motor and said transducer for supplying ultrasonic electrical signals generated by said ultrasound signal generator to said ultrasound transducer.
