Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a rectal protection device for colonoscopy. Background Art

[0002] At present, electronic colonoscopy has become an important detection method for early cancer screening, intestinal polyp diagnosis and treatment. During electronic colonoscopy examination and treatment, the colonoscope body needs to enter the anus and continue through the anus and rectum to reach the ascending colon and even the cecum and appendix opening. During the examination, lubricating fluid will be applied to the anus and the colonoscope body.

[0003] However, unnecessary wear and tear will still be caused to the mucosa near the rectum and anus when the instrument enters and exits the anus for examination and treatment, causing discomfort or even injury after the examination. Especially for those who are particularly nervous, they may clamp the colonoscope too tightly after it enters the body, which will make it difficult for the colonoscope to enter, thus causing unnecessary damage.
