Downgoing reverse colon inspection device having magnet and "wheat awn" bionic united power

Abstract

The invention relates to a downgoing reverse colon inspection device having magnet and "wheat awn" bionic united power. The downgoing reverse colon inspection device comprises a capsule endoscope, wherein a magnetic carrier sleeve sleeves the capsule endoscope, and packages the rear end and the side surface of the capsule endoscope; a plurality of tail whiskers are arranged on the outer side surface of the carrier sleeve, are on the carrier sleeve, and form a gathering effect along an axis of the carrier sleeve; the gathering head end faces the traction direction of the capsule endoscope, so that resistance is formed in the direction opposite to the traction direction; the edge of the tail end of the carrier sleeve is connected with an outer sleeve pipe with a graduation line; the center of the tail end of the carrier sleeve is connected with an inner core; a handle is arranged at the tail end of the inner core; a fixing ring is fixed to the front end of the carrier sleeve; a sliding ring sleeves the carrier sleeve; a spring is connected between the fixing ring and the sliding ring, and is wound on the carrier sleeve; a plurality of upper dragging buttons are symmetrically and fixedly arranged on the outer side surface of the sliding ring; and lower dragging buttons which correspond to the upper dragging buttons are fixedly arranged at the tail part of the pipe wall of the outer sleeve pipe. According to the downgoing reverse colon inspection device disclosed by the invention, the tail whiskers simulate the physical structure of wheat awn, so that the capsule endoscope caneasily reverse in the colon.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for reverse colon inspection with a magnet and "wheatgrass" bionic combined power downward. Background technique [0002] Colorectal cancer is one of the common tumors in the world. Due to the lack of specific clinical manifestations of early colorectal cancer, treatment is often delayed due to missed diagnosis and misdiagnosis. Most patients are already in the middle and late stages when they see a doctor. Since 1969, colonoscopy has been used in the diagnosis and treatment of colorectal diseases. Colonoscopy is a method of inserting the colonoscope into the ileocecal through the anus, and observing the large intestine lesions from the mucosal side during the withdrawal process. Inspection Method. For patients with bloody stools, changes in defecation habits, and changes in stool properties, early colonoscopy is helpful for early diagnosis and treat...
