Embodiment 1

[0023] An ultrasonic transducer generally includes at least an ultrasonic vibrator and electrode leads. The ultrasonic vibrator is an acoustic-electric conversion device, and the electrode leads connect the electrical signal converted by the ultrasonic vibrator to the outside. Among them, the annular array transducer requires the transducer vibrator to be arranged in 360 degrees, and the vibrator units must not be connected, and the arrangement is neat and consistent, and the welding process of the circuit and the vibrator unit requires high requirements, difficult production, low efficiency, and low cost. high. Therefore, how to provide a ring-shaped ultrasonic transducer with good performance and high quality, which has low difficulty in production process and high production efficiency is a technical problem to be solved urgently.

[0024] This embodiment provides a method for manufacturing an annular array transducer, which can arrange the vibrator units neatly and consis...

Embodiment 2

[0041] This embodiment provides a ring array transducer, such as Figure 4 , 5 As shown, it includes at least: a ring-shaped ultrasonic vibrator layer 21, a flexible circuit layer 22.

[0042] The ultrasonic vibrator layer 21 includes a plurality of ultrasonic vibrator units 210 . As shown in the figure, the ultrasonic vibrator units 210 are arranged in a circular array that is not connected, neatly and uniformly concentric and equidistant.

[0043] The flexible circuit layer 22 includes a first portion 221 and a second portion 222,

[0044]The first part 221 of the flexible circuit layer is attached to the back side of the ultrasonic vibrator unit 210 and electrically connected;

[0045] The second part 222 of the flexible circuit layer is a part of the first part 221 that extends in the longitudinal direction and is longer than the part of the ultrasonic vibrator layer 21, and the second part 222 of the flexible circuit layer is along the distance between the ultrasonic vi...

Embodiment 3

[0052] Endoscopic ultrasonography (EUS) is an inspection technology that combines endoscopy and ultrasound. A miniature high-frequency ultrasound probe is placed on the top of the endoscope. The real-time scanning of ultrasound under the endoscope can obtain the histological characteristics of the cavity and the ultrasound images of the surrounding adjacent organs, thereby further improving the diagnostic level of endoscopy and ultrasound.

[0053] This embodiment provides an ultrasonic endoscope, which at least includes the annular array transducer described in Embodiment 2, or the transducer prepared according to the method described in Embodiment 1.

Abstract

The invention provides an annular array transducer, its preparation method and an ultrasonic endoscope. The method of the present invention includes attaching a flexible circuit board on the back of the ultrasonic vibrator board, making the electrodes on the ultrasonic vibrator board correspond to the circuits on the flexible circuit board; cutting the ultrasonic vibrator board longitudinally and the flexible circuit board, so that the ultrasonic vibrator board is cut into a plurality of ultrasonic vibrator units, so that the flexible circuit board is cut with a plurality of grooves; taking the longitudinal axis as the central axis, forming the The ultrasonic vibrator board and the flexible circuit board are ring-shaped, and form a ring-shaped array transducer. The method provided by the invention reduces the difficulty and time of slotting, reduces the production difficulty, improves the production efficiency and ensures the product quality.

Description

technical field [0001] The invention relates to the field of medical ultrasonic imaging equipment, in particular to an annular array transducer, a preparation method thereof, and an ultrasonic endoscope. Background technique [0002] Annular array transducer refers to an ultrasonic transducer with ultrasonic vibrators arranged in a 360-degree circle and capable of 360-degree scanning. It is mostly used for ultrasonic inspection in body cavities. Due to the special structure of the 360-degree vibrator arrangement of this kind of transducer, there are technical difficulties in its preparation and production, such as high process requirements, difficult production, low efficiency, and high cost. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for preparing an annular array transducer in a first aspect, the method comprising the following steps: [0004] Attaching a flexible circuit board to the back of the ultr...
