  • Patent number: 7645245
    Abstract: An endoscopic lithotripsy probe apparatus includes a probe, ultrasonic-vibration source, mechanical shock generation source, and switch-mechanism. The ultrasonic-vibration source is detachably attached to the probe to transmit an ultrasonic-vibration to the probe in a state in which the proximal end of the probe is connected to the ultrasonic-vibration source. The mechanical shock generation source, which is disposed on the side of the proximal end of the probe, applies a force to the ultrasonic-vibration source in a state in which the ultrasonic-vibration source is detached from the proximal end of the probe, and allows the ultrasonic-vibration source to collide with the proximal end of the probe so that a mechanical shock is applied to the probe. The switch-mechanism switches a state in which the ultrasonic-vibration from the ultrasonic-vibration source is transmitted to the probe and a state in which the mechanical shock from the mechanical shock generation source is transmitted.

  • Patent number: 6306131
    Abstract: An electric medical apparatus according to the present invention performs an incising treatment automatically after the coagulating treatment has been performed without a necessity for an operator to perform another operation between the two treatment operations when the incising treatment performs after a coagulating treatment. The electric medical apparatus comprises a CPU, a waveform generating circuit, an amplifier and an output control unit to supply an output for performing the coagulating treatment to a treatment device and an output for performing the incising treatment to the treatment device. The impedance of a living tissue with which the treatment device is brought into contact is measured and calculated by a voltage sensor, a current sensor and an impedance calculating portion.
