Problems solved by technology

[0010] However, in order to reduce the diameter of the above-mentioned printed circuit board, it is conceivable to reduce the number of elements of the ultrasonic vibrator or to further reduce the interval between the above-mentioned signal pattern and the pad electrode at the end of the signal pattern. However, as described above, it is difficult to reduce these intervals.

[0120] Figure 15 It is a plan view showing the upper surface of a printed circuit board on which signal lines corresponding to a plurality of ultrasonic vibrators are arranged in an ultrasonic endoscope including an ultrasonic probe according to a third embodiment of the present invention.

[0121] Such as Figure 15 As shown, the ultrasonic vibrator printed circuit board 301 in the third embodiment has the same function as the ultrasonic vibrator printed circuit board 101 in the first embodiment in that a signal pattern from the ultrasonic vibrator is arranged. However, unlike the first embodiment, the third embodiment is characterized in that a plurality of signal pattern groups are separated and bent on both sides of the circuit board, and that the pad electrode portion at the front end is also placed on the circuit board. The two sides are separated and arranged along the longitudinal axis direction, and both pass through the direction changing circuit board, thereby cha...

Abstract

The diameters of an ultrasonic probe and an ultrasonic endoscope are decreased, and electrical connection in respect of a signal line extending from the ultrasonic vibrator is reliably and easily made. The ultrasonic probe comprises vibrator wiring pads (102) provided at the front end of an ultrasonic vibrator printed board (101) where signal patterns for signal transmission / reception of ultrasonic vibrators are formed, flexible printed board wiring pads (108) arranged in line along the longitudinal axis of the ultrasonic vibrator printed board (101), second signal patterns (106) connected between the vibrator wiring pads (102) and the flexible printed board wiring pads (108) and bent generally 90 degrees at intermediate portions, and a relay flexible printed board (121) connected to the flexible printed board wiring pads (108) and used to change the direction of the signal patterns to the longitudinal axis direction.

Description

technical field [0001] The present invention relates to an ultrasonic probe provided with a plurality of ultrasonic vibrators arranged at a distal end of an endoscope insertion portion, and an ultrasonic endoscope provided with the ultrasonic probe. Background technique [0002] Ultrasonic diagnostic devices that transmit ultrasonic waves to living organisms such as the human body and receive echo signals reflected by living tissue to obtain tomographic images in the living body can obtain image information inside the living body non-invasively and in real time, so they are widely used in diagnosis. important tasks in the medical field. [0003] In addition, there is known an ultrasonic endoscope having an ultrasonic probe in which a plurality of ultrasonic transducers are arranged in a convex arc shape, a so-called convex shape, and these ultrasonic transducers are sequentially moved at high speed for a fixed time and at a fixed interval. The ground is electrically switche...
