Ultrasonic therapeutic apparatus

Abstract

Abstract PURPOSE:To attempt to improve therapeutic efficiency and to obtain miniaturization and lightweight by amplifying ultrasonic oscillation generated by means of an ultrasonic oscillator by means of a horn and radiating it from an oscillating plate fixed on an apex part of the horn into a living body through an ultrasonic transmitting means. CONSTITUTION:A tube 24 such as a catheter, a tube etc., is introduced percutaneously or orally into the gall bladder 21 from a drug soln.-feeding and discharging apparatus 23 and a calculus dissolving agent is fed, discharged and recycled in the gall bladder 21 through the tube 24. The gall bladder thus filled with a calculus dissolving agent is irradiated with an ultrasonic wave from an ultrasonic probe 1 to accelerate a dissolving action of the calculus 22 with the calculus dissolving agent. In this case, as a small and simple Langevin oscillator 3 amplifies and oscillates an oscillating plate 11 with a diameter smaller than the wave length of an exciting oscillation by means of the horn 7, a strong ultrasonic wave can be radiated to a wide range in the body. Therapeutic efficiency can be improved without an accurate positioning.
