Embodiment Construction

[0020] Such as figure 1 , figure 2 , image 3 and Figure 4 Shown, a kind of perfusion driven colon endoscope, it comprises a sliding balloon 1, a charge-coupled device (CCD) lens 2, a connection line 3, an endoscope system 4, a perfusion instrument 5, a perfusion tube 6 and an anal pad 7.

[0021] The sliding airbag 1 is made of a strong elastic thin wall, which becomes a bee-waist when it is inflated, and has a bee-waist depression in the middle. After the sliding air bag 1 is inflated, it can cling to the intestinal wall and slide relative to the intestinal wall. Among them: 1. Since the airbag wall is smooth and elastic, it will not cause damage to the intestinal wall; 2. The wasp-shaped concave airbag is like a double barrier to prevent the leakage of the liquid injected into the intestinal cavity, thereby ensuring the forward speed of the airbag.

[0022] The CCD lens 2 is arranged before the sliding airbag 1 . In this embodiment, the CCD lens includes a cold ligh...

Abstract

The invention discloses a perfusion-driven colonoscope which comprises an anal cushion, a sliding air sac, a charge-coupled device lens, an endoscope system, a connecting wire and a perfusion system, wherein the charge-coupled device lens is arranged in front of the sliding air sac; the endoscope system is provided with a cold light source system, an inflating system and a data receiving system; the connecting wire passes through the anal cushion in a sealed sliding manner and is provided with a video light guide wire for connecting the lens and the data receiving system and the cold light source system and an air pipeline for connecting the air sac and the inflating system; the perfusion system comprises a perfusion instrument and a perfusion pipe, one end of the perfusion pipe is connected with the perfusion instrument, and the other end passes through the anal cushion in a sealed manner; and the air sac can automatically and gradually move along the direction of the enteric cavity under the pressure driving of a perfusion liquid perfused into the enteric cavity, and the lens moves forwards along with the air sac and checks the colon dynamically until the ileocecal junction. Theentrance of the colonoscope is smooth, the colonoscope is prevented from knotting, and the pain of patients in colonoscopy is alleviated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscope for colon inspection. Background technique [0002] Colonoscopy is a very common clinical examination. Because there are many large bends in the direction of the colon, the mirror body is very easy to form a "climb" on the bend of the intestinal tract during the insertion process of the colonoscope, making it difficult to enter the colonoscope. This push-type colonoscopy entrance method is very dependent on the operator's entrance skills, and even skilled operators have certain difficulties in entering the scope. This propulsive method of entering the mirror may also cause medical accidents such as intestinal perforation. In March 2006, "Gastroenterology" reported the Aer-O-Scope product of Israel GIView Company, which is a new type of self-navigation and self-propelled balloon colonoscope without technology dependence. This kind of colonoscope relies ...
