FPC board, ultrasonic transducer and production process thereof and ultrasound endoscope

Abstract

The invention discloses an FPC board, an ultrasonic transducer provided with the FPC board and production process thereof and an ultrasound endoscope provided with the ultrasonic transducer. The FPC board comprises a circuit board body, grounding pieces and multiple cables. The grounding piece is connected with a grounding wire of the circuit board body. A conductor core of a connecting wire end of each cable is fixedly connected with the circuit board body. A shielding layer of a connecting wire end of each cable is fixedly connected with the grounding piece. The FPC board, the ultrasonic transducer and the production process thereof and the ultrasound endoscope have the following beneficial effects: by pre-shaping the multiple cables through the grounding pieces, welding efficiency between the circuit board body and the cables of the FPC board is improved; joints of cable bodies are prevented against breakage; joints among the cables and the circuit board body are prevented against breakage; and greater reliability of the FPC board, the ultrasonic transducer and the ultrasound endoscope is ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an FPC board, an ultrasonic transducer provided with the FPC board and its manufacturing process, and an ultrasonic endoscope provided with the ultrasonic transducer. Background technique [0002] Endoscopic ultrasonography is a digestive tract inspection technology that combines an observation mirror with ultrasound. Both the observation mirror and the miniature high-frequency ultrasonic probe are located at the top of the endoscopic ultrasound. After the endoscopic ultrasound is inserted into the body cavity, the gastrointestinal mucosal lesions can be directly observed through the observation mirror. At the same time, the ultrasonic probe can be used for real-time scanning to obtain the histological characteristics of the hierarchical structure of the gastrointestinal tract and the ultrasonic images of the surrounding adjacent organs, thereby further improving the diagn...

AI Technical Summary

Problems solved by technology

Due to the softness and thinness of the above-mentioned cables, the efficiency of the above-mentioned welding method is very low

Moreover, during the operation of the ultrasonic endoscope, the cable is easily subjected to tension due to bending, which will cause the cable itself or the connection between the cable and the circuit board body (that is, the solder joint of the cable) to break, affecting product reliability.

Moreover, in order to avoid cable breakage, the operating requirements for operators are relatively high
