Abstract: An endoscope system includes: an electronic endoscope having an imaging device and a first processing unit which judges whether a first error has occurred that is an error in image data taken by the imaging device and resets the imaging device if a variable for judgment of occurrence of a first error is larger than or equal to a first threshold value; a light source unit which supplies illumination light to the electronic endoscope, and a second processing unit which judges whether a second error has occurred that is an error in image data transmitted from the electronic endoscope and initializes supply of power to the electronic endoscope if a variable for judgment of occurrence of a second error is larger than or equal to a second threshold value that is larger than or equal to the first threshold value; and a processor as defined herein.

Abstract: A power supply control unit starts power supply to an endoscope if an external trigger is applied (Step S10) (Step S12). If the power supply to the endoscope is started, the endoscope becomes operable. As a result, voltage information showing a current voltage value Vrect is transmitted from the endoscope to the processor device for an endoscope through optical communication as feedback information. A control unit of the processor device for an endoscope receives the voltage information showing the current voltage value Vrect, and outputs the received voltage information to a power supply control unit (Step S14). The power supply control unit adjusts the frequency of an electric current made to flow to a power transmitting coil of a power supply unit, on the basis of the received voltage information (Steps S16 to S24).

Abstract: A surgical apparatus includes a treatment portion, a high-frequency output portion or the like that supplies energy such as a high-frequency current, a liquid feeding tube, a suction tube, a liquid feeding unit, a suction unit, two driving portions, and a CPU as a control portion. Based on stopping of the supply of energy from the high-frequency output portion or the like, the CPU controls at least one of the two driving portions after the supply of energy stops so that an output level of the liquid feeding unit/suction unit becomes higher than an output level of the liquid feeding unit/suction unit during supply of the energy.

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.
