ULTRASONIC DIAGNOSTIC DEVICE

摘要

PURPOSE:To extremely exactly detect the direction of an ultrasonic transmitter/ receiver by providing a mark for displaying the directivity of the ultrasonic transmitter/receiver on at least a base end side from the ultrasonic transmitter/ receiver provided on the tip of a probe inserted through the insert-through line of an endoscope. CONSTITUTION:A mark is provided at least on the base end side from the ultrasonic transmitter/receiver 16, by which at the time of observing this mark 17 by an observation system of an endoscope, it is visible so as to be larger than the ultrasonic transmitter/receiver 16. Therefore, the direction and the position of an ultrasonic transmitting/receiving face 16a can be known easily by this mark 17. Accordingly, an ultrasonic wave can be transmitted/received by allowing the transmitting/receiving face 16a of this ultrasonic transmitter/ receiver 16 to be opposed surely and correctly to the part to be observed or allowing it to adhere closely thereto.
