Anoscope special for rectum pyknosis surgery

Abstract

The invention relates to the field of medical apparatuses, in particular to an anoscope special for rectum pyknosis surgery. The anoscope comprises an anoscope cylinder and an anoscope body; the anoscope cylinder is of a cylindrical structure of which the two ends are opened, and the cylinder diameter of the anoscope cylinder is at least gradually increased from front to back at the front end part; an anoscope inner core comprises an inner core head, a first handle connected with the rear end of the inner core head and a limiting structure; the front end part of the inner core head forms a smooth rotation head, the rotation head can stretch out of an anoscope cylinder front opening, the diameter of the rotation head is gradually increased from front to back, and the diameter of the maximalcross section of the rotation head is larger than or equal to that of the anoscope cylinder front opening; the limiting structure cooperates with the anoscope cylinder to define the depth for the inner core head to stretch into the anoscope cylinder. when the anoscope is adopted for carrying out the rectum pyknosis surgery, laparotomy is not needed, rectum mucosal membranes do not need to be incised, the surgery is minimally invasive, and few complications are caused.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a special anoscope for rectal pyknosis. Background technique [0002] Rectal intussusception, also known as rectal mucosal prolapse, rectal prolapse, or recessive prolapse, refers to rectal mucosal or rectal wall full-thickness sagging during defecation, folding inward into the distal rectal cavity or even the anal canal , thereby blocking the exit of the digestive tract, causing difficulty in defecation. Rectal intussusception mostly occurs in the distal rectum, common in middle-aged people, more women than men, some patients have mental symptoms, pudendal nerve damage in the late stage, and fecal incontinence to varying degrees. [0003] In the prior art, common methods for treating the above-mentioned diseases include circumcision, ligation and rubber band ligation on PPH hemorrhoids. PPH supramucosal circumcision uses PPH circular resection and anastomoses the rectal mucosa, ...

AI Technical Summary

Problems solved by technology

[0004] However, complications such as anastomotic bleeding, stenosis, and infection are prone to occur after PPH hemorrhoidal circumcision; there are many mucosal points ligated in ligation, and the staggered ligation points are likely to cause anal stenosis; the glue used in rubber band ligation The loop ligation is prone to slippage, and the ligation tissue has necrosis and incomplete shedding
