摘要:
An ultrasonic vibration treatment apparatus comprising an ultrasonic vibration treatment device including an ultrasonic vibrator and an ultrasonic wave transmitter probe, a detecting element opposing the transmitter for applying light to the transmitter and receiving the light reflected from the transmitter, thereby to detect the amplitude of vibration of the treatment device, and a power source controller for reducing the power supplied to the vibrator, or stopping the power supply to the vibrator, in accordance with a detection signal output by the detecting element. The detecting element quickly detects the charges in the amplitude of vibration of the ultrasonic vibration treatment device, said charge in the amplitude representing the charges in the vibration condition of the vibration treatment device from actual driving to idling, or vice versa. The power source controller fast responds to the detection signal output by the element, and immediately controls the treatment device in idling state, so as to prolong the lifetime of the treatment device.

摘要:
A ultrasonic therapeutical apparatus comprises a plurality of ultrasonic vibrators which are disposed in a plurality of concentric circular rows and defining a ultrasonic shock wave generator. The apparatus also includes control means for independently controlling the frequency and the phase with which the ultrasonic vibrators in the respective raws are driven as well as the output levels thereof, thereby allowing only a positive pressure of the resultant ultrasonic wave to be increased while suppressing a negative pressure thereof to eliminate a cavitation effect.

A therapeutical apparatus includes a measuring apparatus including a probe which generates an X-ray or ultrasonic wave in order to detect the location of a target to be treated such as calculi situated within the kidney, liver, biliary ducts. A therapeutical energy generator generates a shock wave of sufficient energy for purposes of therapy externally of the physical body and focuses it upon the target. Structure is provided for causing a displacement of the generator and the measuring apparatus around the surface of a patient. Structure is provided to activate the generator.
摘要:
A hyperthermia apparatus for effecting the thermotherapy by heating a cancer locally including two outside-body electrodes to be arranged on an outer surface of a patient's body, an inside-body electrode to be inserted into a cavity of the patient's body, a high frequency power supply circuit for generating a high frequency power, and a switch connected between the high frequency power supply circuit and the electrodes for selectively supplying the high frequency power to two electrodes so that the cancer can be locally heated to a desired high temperature. At each electrode there are provided balloons through which temperature controlled liquid mediums are circulated to prevent portions of the body near the electrodes from being heated to undesired high temperatures. The liquid mediums circulated through the balloons are electrically isolated from each other completely.

A pipe-inspecting apparatus having a self-propelled unit. The self-propelled unit comprises an elastic tube which has forward and rear ends, and into which a fluid is supplied and from which the fluid is discharged, a restriction member mounted on the elastic tube, for restricting an axial expansion of the elastic tube, a bias member for biasing the elastic tube in the axial direction thereof, first and second holding members coupled to the ends of the elastic tube, respectively, for holding the ends of the elastic tube to the inner periphery of a pipe being inspected, while the fluid is being supplied into the holding members, and releasing the ends of the elastic tube from the inner periphery of the pipe, while the fluid is being discharged from the holding members. An observation device is coupled to the self-propelled unit. A display device is connected to the observation device, for displaying the image scanned by the observation device. A fluid control device is connected to the elastic tube, and to the first and second holding members.
