Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to a high light-conducting anoscope. Background Art

[0002] Anorectal diseases are common and frequently occurring diseases unique to humans, so daily anal examinations are very important in clinical diagnosis. Among them, anoscopy is one of the routine examination methods for anal and rectal diseases, and is suitable for the examination of lesions in the anal canal, the terminal rectum, and near the dentate line. Anoscopy can also be used for biopsy. Anoscopy is widely used in the anorectal field, and plays a confirmatory role in the diagnosis of anorectal diseases such as blood in the stool, hemorrhoids, anal atrophy, perianal abscess, rectal prolapse, and anal itching.

[0003] The procedure of anoscopy is usually to press the tip of the anoscope lightly against the anal margin, slowly push it in the direction of the umbilicus, turn it towards the sacral recess after passing through the anal canal, then pull out the core of the scope, shine a light in, observe under direct vision, and then slowly withdraw the scope while observing. During the entire anoscopy procedure, because it is all direct vision, whether the light can be illuminated well will affect the doctor's judgment and even the diagnosis results.

[0004] At present, there are different types of anoscopes on the market that have been put into actual use, but the effects of most anoscopes are not particularly good. Due to the poor structure of the existing anoscopes themselves, the light source passes through the channel of this type of anoscope, and after various reflections and refractions occur, the light that actually illuminates the examination site will be greatly attenuated. In the case of insufficient lighting, it often affects the doctor's judgment and ultimately leads to an incorrect diagnosis. At present, the structure of most anoscopes is to locally improve the light conductivity, which may easily cause uneven brightness and unclear field of view of the examination site after light is introduced, which is extremely unfavorable for the implementation of accurate treatment. In addition, most of the previous anoscopes require more than two times of processing, which increases the process flow in production and easily causes an increase in production costs. At present, there is a lack of a new type of high-light-conductivity anoscope mainly used for anorectal examination, which can greatly enhance the light conductivity of the anoscope from a structural perspective, and make the introduced light source as evenly distributed as possible, reduce the occurrence of local brightness unevenness, and improve the accuracy of clinical diagnosis.

[0005] Therefore, a new technology is needed to solve the problem that the prior art lacks a new type of highly light-conductive anoscope mainly used for anorectal examination. Utility Model Content
