Description

Technical Field

[0001] The utility model relates to the technical field of digestive tract endoscopy, in particular to a mucus removal brush structure for digestive tract endoscopy and multi-modal functional imaging under endoscopy. Background Art

[0002] During endoscopic examinations such as digestive tract endoscopy and endoscopic multimodal functional imaging, the mucus covering the surface of the lesion directly affects the observation of the glandular and vascular structures of the lesion under endoscopy; the reflection and refraction of light by mucus directly affects the analysis of optical data in multimodal functional imaging. More thorough removal of mucus on the surface of the lesion can improve the accuracy of endoscopic digestive tract disease diagnosis and increase the detection rate of early lesions.

[0003] In the prior art, the common way to reduce gastrointestinal mucus is to take single or combined agents such as oral simethicone, chymotrypsin, and pronase to reduce gastrointestinal mucus, or to use local endoscopic irrigation to reduce mucus on the surface of the lesion. However, the surface of many gastrointestinal lesions is uneven, and the mucus in many concave areas cannot be removed by simple oral administration or local irrigation, and strong irrigation can easily damage the surface structure and affect observation; at the same time, large amounts of local irrigation of lesions in the upper esophagus can easily cause patients to choke or even aspirate. The presence of these mucus not only affects our observation of the surface structure of the lesions, but also seriously interferes with our prediction of the depth of lesion infiltration through multimodal functional imaging, which further affects the choice of subsequent treatment options.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a mucus removal brush structure for endoscopes. Utility Model Content
