A surgical device for stapling and fastening body tissues, comprises an insertion section extending from an operation section for insertion into a body cavity, stapling member connected to a distal end of the insertion section, for treating body tissues with a high-frequency current within a body cavity. The stapling member includes an anvil and a cartridge between which the tissues are sandwiched, and a cutter. Staples are applied to the anvil from the cartridge for stapling the tissues and the cutter cuts the tissue while it applies a high-frequency current thereto.

摘要:
A medical treatment device for resecting, e.g., a prostate or breaking a bladder stone, which includes a vibrator for generating ultrasonic vibrations, a horn connected to the vibrator, a casing for accommodating the vibrator and the horn, a probe connected to the front portion of the horn to transmit ultrasonic vibrations generated by the vibrator, and a power source unit for supplying a drive voltage to the vibrator, the power source unit having an oscillator for producing a wave having a frequency for vibrating the probe and a frequency switching circuit for selecting an oscillating frequency at which the distal end of the probe serves as a loop of vibration or a frequency at which the distal end of the probe serves as a node of vibration.
摘要:
An ultrasonic therapeutical apparatus observes the interior of a living body utilizing an ultrasonic wave, allows a location signal to be generated on the basis of an output from the observation system, and controls a focus shifting system in accordance with the location signal. Subsequently, a shock wave generating system is driven to generate an ultrasonic shock wave, which is directed to a focal point, thereby crushing a calculus.

The vehicle stationary/moving determination apparatus includes an antenna mounted on a vehicle body of a vehicle; and a determination device determining whether or not the vehicle is moving or stationary on the basis of a reception intensity of a radio signal transmitted from a radio transmitter device mounted on the vehicle at a portion other than the vehicle body and received by the antenna.
摘要:
A device for closing a spout of a flexible container is provided. The device includes a connection tube and a sealable cap having an outer casing member with a lower, outer circumferential surface, an attachment member annularly positioned on a portion of the lower, outer circumferential surface, and an inner casing member having an inner casing sidewall and a bottom disc-shaped occlusion plate defining a cylindrical void space configured to receive a connection tube. The plate can be integrally connected to the inner casing sidewall via a thin-wall section sized to break by the insertion of an insertion edge of the connection tube. The device can also include an overcap sized to mate to the sealable cap.
