摘要:
An ultrasonic treatment apparatus comprises at least one hand piece, a plurality of probes, and an ultrasonic drive device. The hand piece has an ultrasonic oscillation device for generating ultrasonic vibration. Each probe is adapted to be attached to the hand piece and designed to transmit the ultrasonic vibration generated by the hand piece. The ultrasonic drive device is connected to the hand piece, for driving the ultrasonic oscillation device.

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 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 ultrasound type treatment apparatus includes an ultrasonic oscillation device for outputting an ultrasonic oscillation wave, a drive circuit for driving the ultrasonic oscillation device, a probe connected to the ultrasonic oscillation device to transmit that ultrasonic oscillation wave to an affected region of interest of a human being, a sheath formed around the probe, through which cooling medium is passed and a supply tank for supplying cooling medium to the sheath. In this treatment apparatus, an arithmetic operation circuit monitors a drive state of the ultrasonic oscillation device, a comparator is provided for receiving monitor information from the arithmetic operation circuit and for determining whether or not the supply of cooling medium to the sheath is normal and a controller is provided for stopping a drive of the ultrasonic oscillation device when the supply of the cooling medium is determined by the comparator as being not normal.

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.

An ultrasonic aspirator has a probe having the inside path made an aspirating path by being provided on the base side with an ultrasonic vibrator. The probe is used as an ultrasonic vibration transmitting member and is in contact at the tip with an object within a body cavity to crush the object and to discharge the crushed object out of the probe through the aspirating path. A device, for detecting a break of the probe, is provided so that, when the probe breaks, the vibration of the above mentioned ultrasonic vibrator will be stopped by a signal from the detecting device.
摘要:
An ultrasonic treatment apparatus includes an ultrasonic probe having an ultrasonic vibration generator for generating ultrasonic vibrations and a vibration transmission member for transmitting generated vibrations, and a sheath for covering at least an outer peripheral surface of the vibration transmission member of the ultrasonic probe, and a fluid supply unit, attached to an attaching portion of the sheath, for supplying a fluid into a path defined between the vibration transmission member and the sheath. A seal member for sealing the path is arranged nearer to the vibration generator than the attaching portion of the sheath.

An apparatus for holding a medical instrument, such as an endoscope, in place without exerting an undue force on an insertion hole in an abdominal cavity of a subject even when the arm of a scope-holding section is unlocked, includes a four-link parallelogram mechanism. The four-link parallelogram mechanism includes a support arm for supporting a treating tool, an arm section parallel to the support arm and upper and lower arm sections connected to the upper and lower end sides of the support arm and arm section in a parallel relation. A support mechanism supports the arm sections of the four-link parallelogram mechanism to allow the arm sections to be moved in left/right and up/down directions, while being rotated, so that a straight line connecting an intersecting point P of a center line of the treating instrument inserted into an insertion hole in an abdominal wall of a subject and the center of the insertion hole to spherical bearings of the arm is set parallel to the upper and lower arm sections.
