Problems solved by technology

[0006] Therefore, there is a limit to miniaturization of the ultrasonic probe due to shortening of the distance from the vibrator unit to the opening of the wiring penetration portion, and reduction in the diameter of the wiring penetration portion.

Abstract

A circuit board (55) that is electrically connected to the back surface of an ultrasound transmitter-receiver (51) for transmitting and receiving ultrasonic waves has a configuration that is provided with a rigid circuit board (56) that configures a rigid section and a jacket section (59) extending from the rigid circuit board (56) (rigid section). Multiple drive wires (62), which are electrically connected to the circuit board (55), are inserted, wrapped and bundled by the jacket section (59), into a wire insertion section (72) of a housing (70).

Description

technical field [0001] The present invention relates to an ultrasonic endoscope in which a vibrator unit is accommodated in a casing provided at a distal end portion of an insertion portion. Background technique [0002] Conventionally, an ultrasonic endoscope having an ultrasonic probe at the distal end of an elongated endoscope insertion portion has been widely used in the medical field and the like. This ultrasound endoscope constitutes an ultrasound endoscope system together with, for example, an ultrasound observation device, a monitor, and the like. Furthermore, in this ultrasonic endoscope system, for example, ultrasonic tomographic images in the subject can be acquired by transmitting ultrasonic waves from the ultrasonic probe to the subject and processing the received ultrasonic echo signals with the ultrasonic observation device. [0003] An ultrasonic probe used in such an ultrasonic endoscope has, for example, a transducer unit in which a plurality of ultrasonic...
