摘要:
An ultrasound type treatment apparatus includes an inner sheath covering an ultrasonic transmission member having a first suction passage and defining a space relative to the ultrasound transmission member and an outer sheath covering the inner sheath and defining a space relative to the inner sheath. In the treatment apparatus, a liquid medium supply passage is provided at one of the space between the ultrasound transmission member and the inner sheath and space between the inner sheet and the outer sheet to supply a liquid medium to the distal end of the ultrasound transmission member. A second suction passage is formed at the other of the space between the ultrasound transmission means and the inner sheath and space between the inner sheath and the outer sheath. The first suction passage is connected by a suction tube to the second suction passage.

An ultrasonic treatment apparatus comprises a hand piece, and an RF power supply unit. The hand piece includes vibrator cover, a sheath connected thereto, a hollow cylindrical member, an ultrasonic vibrator in the cover for generating ultrasonic vibrations, a probe arranged in the sheath, for externally transmitting ultrasonic vibrations generated by the vibrator, and a cord for transmitting a high-frequency current from the RF power supply unit to the probe. The cover and sheath are composed of an insulating member, for preventing the high-frequency current transmitted by the probe from being externally leaked.

An ultrasonic treating apparatus includes an inpedance detection unit for detecting the impedance of an ultrasonic vibration element for transmitting ultrasonic vibrations and a determining unit for determining whether the ultrasonic vibration element is good or not. If the ultrasonic vibration element is found not to be good, then a control unit inhibits ultrasonic vibrations from being generated from the ultrasonic vibration element. It is thus possible to prevent any breakage of the apparatus.

摘要:
When a user steps on a footswitch, high-frequency output power is delivered. A control circuit included in a diathermic power supply calculates the impedance ZSn that is offered by a living tissue immediately after delivery of high-frequency output power is started during the n-th delivery period. The control circuit also calculates the impedance ZEn that is offered thereby immediately before delivery of high-frequency output power is discontinued with elapse of predetermined time. The control circuit then discontinues delivery of high-frequency output power for the predetermined time, and calculates a difference ΔZn between the impedances. When the difference meets a predetermined condition that implies coagulation or when the number of times of delivery reaches a predetermined value, the control circuit discontinues delivery of high-frequency output power.
