The invention discloses a transducer of an ultrasonic endoscope. The transducer comprises a main body and a core support barrel; the main body comprises piezoelectric vibrators arranged evenly and circumferentially, a matching layer located on the outer layer of the piezoelectric vibrators, a lining material located on the inner layer of the piezoelectric vibrators and an acoustic lens arranged on the exterior of the matching layer in a covering mode; the main body is fixedly arranged on the exterior of the core support barrel in a sleeving mode, and the two ends of the core support barrel are each provided with a connection portion. According to the transducer of the ultrasonic endoscope, the interior of the transducer does not need to be filled with epoxy materials, the interior of a cavity of the core support barrel can be used for arranging parts such as a water injection channel, a forceps way pipe, an optical fiber and a cable, and therefore disassembly, maintenance and replacement are convenient; in addition, the core support barrel serves as a connecting part for connecting the front portion and the back portion of the transducer, the production and assembly technology can be effectively simplified, and therefore the production efficiency is improved. The invention further discloses the ultrasonic endoscope with the transducer.
Description
technical field [0001] The present invention relates to the field of ultrasonic technology, more specifically, to a transducer of an ultrasonic endoscope, and also to an ultrasonic endoscope including the transducer. Background technique [0002] In clinical medicine, endoscopes are more and more widely used in clinical diagnosis and treatment. With the development of modern technology, the design of endoscopes is becoming more and more humanized and modern. Using modern high-tech It makes the design and manufacture of endoscopes more intelligent. Medical endoscopic ultrasonography uses an ultrasonic microprobe to probe into the human body on the basis of an electronic endoscope, and through scanning, displays three-dimensional three-dimensional lesions, obtains information on the corresponding parts, and achieves the purpose of inspection and diagnosis. [0003] Ultrasound endoscopy is an organic combination of ultrasound and endoscope. Its principle is to use endoscope an...
