Abstract
An ultrasonic endoscope includes an operation section and an insertion section extending therefrom. A driving member having a magnet is disposed in the distal end of the insertion section to be rotatable. The member is rotated by a motor through a transmission shaft. An ultrasonic scanning unit is removably attached to the distal end of the insertion section. The unit has a casing in which a scanning chamber filled with a liquid ultrasonic transmission medium is defined. A ultrasonic generator is disposed in the casing. A rotating mirror for reflecting the ultrasonic waves generated by the generator is rotatably arranged in the chamber. A driven member is rotatably arranged in the chamber and coupled to the mirror. The driven member has a magnet magnetically connected to the magnet of the driving member so that it rotates as the driving member rotates.
