A control switch detecting apparatus aims at detecting a control switch operable by an operator for controlling a medical device. When a position signal for representing a position of at least one of the control switch and the operator is transmitted from at least one of the control switch and the operator, an obtaining unit obtains relative position information indicative of a relative positional relationship between the control switch and the operator based on the transmitted position signal.

Method and apparatus for detecting a control switch for medical equipment

An ultrasonic lithotripter comprising a first transmission probe which has a hollow portion in the form of a through hole and transmits ultrasonic vibration and a superfine second transmission probe which can be passed through the hollow portion of the first transmission probe. An object of manipulation is held by means of the second transmission probe as it is manipulated by means of the first transmission probe.

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.

An image signal captured by a camera head and outputted from an image processor is inputted into a foot switch control device. The image signal is processed in a display control unit of the foot switch control device, inputted into a display and displayed thereon. The display control unit reads out an image indicating the foot switch state corresponding to the foot switch function that is presently allocated to the inputted endoscopic image from a memory unit and superimposes this image on the endoscopic image.

Control device for a medical system and control method for medical system

An ultrasonic driving apparatus consists mainly of a digital oscillatory circuit, an amplifier, a detection circuit, a phase difference detection circuit, a register, a data transfer circuit, and a switching circuit. The digital oscillatory circuit is used to drive an ultrasonic transducer at the resonance frequency of the ultrasonic transducer. The amplifier amplifies a driving signal output from the digital oscillatory circuit. The detection circuit detects the phase &#x3b8;v of an applied voltage and the phase &#x3b8;i of an induced current from the driving signal applied to the ultrasonic transducer via the amplifier. The phase difference detection circuit detects a difference between the phases &#x3b8;v and &#x3b8;i. The register holds digital frequency data with which a frequency at which the digital oscillatory circuit is oscillated is determined, and changes the digital frequency data. The data transfer circuit transfers the digital frequency data to the register. The switching circuit is interposed between the phase difference detection circuit and register.
