Endoscope with direct view of anal orifice and rectal intestine

Abstract

The invention relates to an endoscope through which the anorectal situation can be seen directly. The endoscope consists of an endoscope body, an inner core, a handle and a illuminating apparatus. The endoscope body is made of transparent materials, a ring of point sources of light are provided at the inner opening of the endoscope body, the two electrodes are connected with an electric power which could be an embedded battery, and a control switch is positioned on the handle. Direct observation of the middle and lower parts of the anorectal canal at a crimple state or an expansion state can be performed.

Description

technical field [0001] The invention relates to an endoscope capable of looking directly at the anus and rectum, belonging to the scope of medical instruments. Background technique [0002] The traditional anorectal endoscope is made of metal materials, and the anal canal and rectal wall are gradually observed through the inner opening of the anoscope. The anal canal and the middle and lower rectum, especially the dentate line, are often shrunken due to the action of the anal sphincter and rectal muscles, and the anal recess and anal sinus in the structure around the dentate line are blind pockets with upward openings, and the rectal mucosa also forms multiple The traditional anorectoscope can only observe the lesions through a single view of the internal opening, and due to the above anatomical structure, the observed view is mostly shrunken tissue, especially the lesions around the dentate line, and most anorectal diseases such as Hemorrhoids, anal fistula, anal cryptitis...

AI Technical Summary

Problems solved by technology

The anal canal and the middle and lower rectum, especially the dentate line, are often shrunken due to the action of the anal sphincter and rectal muscles, and the anal recess and anal sinus in the structure around the dentate line are blind pockets with upward openings, and the rectal mucosa also forms multiple The traditional anorectoscope can only observe lesions through a single view of the internal opening, and due to the above anatomical structure, the observed view is mostly shrunken tissue, especially the lesions around the dentate line, and most anorectal diseases such as Hemorrhoids, anal fistula, anal cryptitis, etc. are all prone to occur in this part

Clinicians often cause many misdiagnoses and missed diagnoses due to the inability to fully expand the above shrinkage structures
