Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary instruments, and in particular is a multifunctional colonoscopy auxiliary device. Background Art

[0002] A colonoscope is a slender, flexible medical instrument with a diameter of about 1 cm. It is passed through the anus into the rectum and into the large intestine, allowing doctors to observe the internal conditions of the colon and large intestine. Colonoscopy is a diagnostic method used by doctors to examine the large intestine and internal lesions of the colon. The standard posture for colonoscopy is side-lying with the knees bent. Some patients who have undergone surgical operations may need to lie in the supine position. There are two types of colonoscopies: normal and painless.

[0003] In the prior art, when performing colonoscopy in the side-lying position with the knees bent, the patient needs to bend both knees, bring the thighs as close to the abdomen as possible, and expose the buttocks as much as possible. During the colonoscopy, the anus can be fully exposed to facilitate the entry of the colonoscope, and the abdomen should be relaxed as much as possible when the knees are bent to avoid abdominal muscle tension. However, during ordinary colonoscopy, pain will occur, causing the patient's position to shift, resulting in a non-standard side-lying position with the knees bent, which will cause leg fatigue.
