Description

结肠镜用多功能外套管装置技术领域 Multifunctional outer cannula device for colonoscopy

[0001] 本发明涉及一种用于结肠镜检査的辅助设备，具体涉及结肠镜用多功能外套管装置。 [0001] The present invention relates to an auxiliary device for colonoscopy, and more particularly to a multifunctional outer cannula device for colonoscopy.

背景技术 Background technique

[0002] 现有结肠镜为软式内镜，在通过乙状结肠、脾曲、肝曲等弯曲部位吋，内镜容易形成弯襻，性能纤细柔软的内镜鼻胃镜：用鼻胃镜做肠镜受检者几乎无痛苦更易打弯成襻，会给内镜的***造成困难。结肠镜的寻腔方法分为注水式和注气式两种。当肠道内注水量过多吋液体会由***排出，导致检査床及受检者本人的衣裤被污染。当肠管充气过多受检者会觉得腹胀不适。 [0002] The existing colonoscope is a soft endoscope. In the curved part of the sigmoid colon, the spleen, the liver sac, etc., the endoscope is easy to form a curve, and the endoscope is a soft and flexible endoscope: the endoscope is used for the endoscopy. The examiner is almost painless and more likely to bend into a mole, which can cause difficulties in the insertion of the endoscope. The cavity searching method is divided into two types: water injection type and gas injection type. When the amount of water in the intestine is too much, the liquid will be discharged from the anus, causing the examination bed and the subject's own clothes to be contaminated. When the intestine is inflated too much, the subject may feel uncomfortable with bloating.

技术问题 technical problem

[0003] 本发明为了解决软式内镜在进镜过程中尤其是通过乙状结肠部位吋容易形成弯襻和向肠腔内注水导致液体由***排出污染检査床、衣裤及注气过多给受检者会带来腹胀不适的问题，提供结肠镜用多功能外套管装置。 [0003] In order to solve the problem that the soft endoscope is easy to form a curve and inject water into the intestinal cavity during the process of entering the mirror, the liquid is discharged from the anus by the anus to inspect the bed, the underwear and the gas injection. The subject will have problems with bloating discomfort, and a multi-functional outer cannula device for colonoscopy is provided.
