Sleeved laminated anoscope

Abstract

The invention is concerned with the c, includes the lens barrel of the anoscope, the tunnel, the lens core fixer, the handle, the plug handle, the stieda body, the plug head, the characteristic is: the lens barrel of the anoscope is hollow taper that is set moveable inner covering lens in it, the convex table on the stieda body, the front of the convex table is the plug head of the coniform. The invention is fit for the PPH operation and hemorrhoids negative pressure machine. It is: uses the rake of inner plug to insert the anus easily, processes accurate operation on 1cm - 2cm of tooth traces by anoscope, processes accurate operation on 3cm - 5cm of tooth trace by inner covering lens, the purse-string suture line cannot be too deep or too fleet of mucous membrane sewing on the horizontal, in order to improve the integrality of ring cutting organic effectively.

Description

technical field [0001] The invention belongs to surgical diagnosis and treatment instruments, in particular to an anoscope used for diagnosis and treatment of anorectal diseases. Background technique [0002] In 1975, Thomson put forward the "Anal Cushion Theory", which promoted people's re-understanding of hemorrhoids, and also led to the transformation of hemorrhoid treatment methods. Among the many methods for the treatment of hemorrhoids, stapler hemorrhoids circumcision ( PPH surgery) is the most revolutionary. The key to its curative effect is the height of the purse string suture, the width and depth of mucosal resection. The technical requirements for treatment and other aspects are relatively high. The domestic hemorrhoid negative pressure ligation device also promotes the development of hemorrhoid surgery methods. The therapeutic effects of these two technologies are absolutely related to the accurate positioning of the anoscope. At present, the PPH surgery The le...

AI Technical Summary

Problems solved by technology

At present, the length and diameter of the anal expander used in PPH surgery are both 3.5cm, and the top and bottom are equally thick, so it is difficult to insert into the anus, and it is impossible for patients with short anal canal to operate on the tooth line 1-1.5cm; commonly used stainless steel and disposable The length of the plastic anoscope is generally 5-7cm. Due to the different lengths of the anal canal of the patients, it is difficult to locate it accurately during treatment, which affects the therapeutic effect of the domestic hemorrhoid negative pressure ligation device.
