Abstract
An ultrasound examination system, including an ultrasound probe detachably connected at its proximal end to a probe operating unit and having an ultrasound transducer rotatably mounted on the tip end of a flexible insert member and a rotation transmitting means passed through the insert member to rotate the ultrasound transducer. The probe operating unit is provided with a linear operating means for displacing the ultrasound transducer linearly for a linear scan, and a radial operating unit for rotating the ultrasound transducer for a radial scan, in combination with a mode selector means for switching the operation of the ultrasound transducer between linear scan mode in which the transducer is displaced linearly during transmission and reception of ultrasound signals and a radial scan mode in which the transducer is rotated during transmission and reception of ultrasound signals.
