Abstract

The invention relates to the technical field of medical equipment, in particular to an enteroscope balloon. The enteroscope balloon comprises a longitudinally arranged fixed tube, a movable sleeve sleeved with the fixed tube, a first rubber piston, a dilation balloon, a sealing rubber ring and a push-pull device; the fixed tube and the movable sleeve are each of a hollow structure, the extended end of the movable sleeve stretches into the dilation balloon, the sealing rubber ring is used for making the movable sleeve and the dilation balloon connected, the upper end of the fixed tube is connected with the push-pull device, retraction and stretching of the movable sleeve are controlled by means of vertical movement of the second rubber piston in the push-pull device, the movable sleeve retracts, the sealing rubber ring and the dilation balloon achieve automatic separation from the movable sleeve, the dilation balloon is left in the colon, a dilation balloon physically blocks port side intestine peristaltic wave to be transmitted to the anorectal colon, large intestine peristalsis is weakened, and by means of the physical supporting effect of the dilation balloon, an operation spaceand clear vision are provided for endoscopic treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a colonoscope balloon. Background technique [0002] With the change of life and diet and the impact of the environment, the incidence of intestinal diseases has greatly increased. Colonoscopy is currently a medical device widely used in the diagnosis and treatment of intestinal diseases in major hospitals. According to relevant literature statistics, in the operation of colon endoscopy In 29% of the patients, colonic motility increased after high-frequency electric cutting stimulation, and 82.7% of them reached the level that affected the surgical operation. Patients had frequent colonic motility, unclear operation field of view, increased difficulty of operation, increased risk of colonic perforation, and even gave up internal surgery. Endoscopic treatment was changed to surgical laparotomy. Furthermore, the intestinal lumen is closed, and the doctor must increase gas ...
