Endoscope shape detection device

Endoscope shape detection device

The source coil drive circuit section (31) of an endoscope profile detector (3) comprises an oscillator (110) generating a sine wave, and an amplifier (111) for amplifying the sine wave and generating (driving) an AC field in a source coil (14i) through a switch section (112). The switch section (11...

Zusammenfassung:The source coil drive circuit section (31) of an endoscope profile detector (3) comprises an oscillator (110) generating a sine wave, and an amplifier (111) for amplifying the sine wave and generating (driving) an AC field in a source coil (14i) through a switch section (112). The switch section (112) can supply a DC current to the source coil (14i) while switching to the output of the amplifier (111). The source coil drive circuit section (31) is provided with a DC resistance detecting section (113) for measuring the DC resistance of the source coil (14i) from a potential drop when the switch section (112) is supplying a DC current to the source coil (14i).
