Chinese Scientists Successfully Developed Ultrasound Endoscopic Probes

- Jun 04, 2019-

The reporter learned from the Suzhou Medical Institute of the Chinese Academy of Sciences that the team led by the Institute of Medical Acoustics Research has recently developed an ultrasound endoscopic microprobe for human digestive tract and intestinal lesions. This new instrument is better able to image the lesions so that doctors can more accurately identify the staging of the digestive tract and develop a treatment plan.

At present, the new probe has achieved small batch production and is expected to enter the product registration phase within two years.

Ultrasound endoscopy is a technique for applying ultrasound to imaging examination of the lumen of the human body. It places a miniature high-frequency ultrasound probe at the front end of the interventional catheter, inserts the esophagus, gastrointestinal, bronchial, etc. for real-time scanning imaging.

The endoscope microprobe developed this time, the core component is a rice-sized ultrasonic transducer. The latest imaging tests show that this transducer clearly sees the five-layer structure of the stomach wall to meet clinical needs. By using an ultrasound endoscope, the doctor can clearly identify the tumor growth level and depth of invasion. In addition, the ultrasound endoscope can also be applied to the imaging of organs near the intestine, and plays a role in the diagnosis of lesions of the pancreas, bile duct, and gallbladder.

Compared with traditional optical endoscopy or X-ray imaging, ultrasound endoscopy is much more informative and more convenient and safer than puncture. "For example, the traditional gastrointestinal mirror is equivalent to the visceral 'sight mirror', only to see the surface of the inner wall of the organ, and the ultrasound endoscope is equivalent to the probe into the body to do B-ultrasound. With the technology Ascension, in the future, you can get higher resolution, more depth of penetration images, help surgeons better to get the right medicine, or take a better surgical strategy."
