Abstract

An intracavitary ultrasound probe comprises a rotating shaft rotatably supported inside an elongated body and adapted to swing or rotate a transducer element, an motor housed in a handle, and a stab needle guide extending in substantially parallel to the elongated body. The motor is arranged in a manner to be offset from the rotating shaft, and the ultrasound probe further comprises a mechanism for transmitting torque from the motor to the rotating shaft. Since, therefore, the handle is offset from the elongated body, a wide space for operating a stab needle is provided, thus ensuring easy operation of the stab needle. In addition, a wide space for employing a syringe is also provided. As a result of this structure, the patient's pain is reduced, and the probe is easy to rotate or tilt.
