Abstract

Anoscope for transanal excision of the rectal mucosa, consisting of a hollow cylindrical tube, characterized in that the anoscope consists of two parts, one of which is a hollow tube 9 cm long, the distal and proximal ends of which are made in the form of a sector with a radial wall height of 43 mm and the distance between the radial and arcuate walls of 43 mm with the hook attached to the proximal edge of the anoscope inside the ligature of the ligature retainer, and the other - the ligature retainer consists of a handle, a hook ring rings for ligatures.

Description

Anoscope for transanal excision of the rectal mucosa.

The utility model relates to medicine, namely to proctology and can be used for transanal excision of the rectal mucosa. Hemorrhoids ranks first in incidence in coloproctology. Effective methods of treating hemorrhoids and prolapse of the rectum are transanal excision of the mucosa at a distance of 5 cm from the anorectal line, since the use of these treatment methods can reduce pain and restore disability in a short time. (A method for the treatment of hemorrhoids and prolapse of the rectum. Patent No. 2177739 of 01/10/02)

As an analogue, the authors propose an anoscope consisting of a cylindrical tube 8 cm long and 23 mm in diameter (Big Medical Encyclopedia. Edited by B.V. Petrovsky. Vol.3.1983 Vol. 21.st. 270/1). The disadvantage of this analogue is;

- it is impossible to simultaneously assess the volume of the falling out mucosa and to perform a suture of the mucous membrane.

-Difficulties arise in performing a metered resection of the rectal mucosa, due to imperfections in the design of the anoscope

As a prototype, the authors propose an anoscope for purse string suture (PSA33) that is inserted through an anal circular dilator (CAD33). An anoscope for applying a purse string suture is a hollow cylindrical tube with a diameter of 33 mm with a slot on one of the walls 1.5 cm wide, for introducing a needle with a thread and a needle holder and two handles, with which the anoscope can rotate in the anal dilator

(Anestoscope for applying a purse string suture PSA33, set РРН01. Catalog. Ethicon Limed. Ethicon Endosurgery. United Kingdom.)

The disadvantage of this prototype is:

difficulties arise when applying guide seams during

fitting to determine the volume of excision of the rectal mucosa, since this design of the anoscope was created to perform a purse string suture, which is carried out only after setting it into the rectum.

Excision of the rectal mucosa flap is difficult due to the inability of the anoscope for linear staplers.

stitching and excision of the rectal mucosa is carried out blindly, since instead of an anoscope for applying a purse string suture, a circular stapler with a diameter of 33 mm is introduced. (HC833) which completely closes the lumen of the anal dilator.

The purpose of the invention is improving efficiency and reducing the frequency of relapses.

The authors propose an anoscope for transanal excision of the rectal mucosa. It consists of two parts: a hollow tube 9 cm long. The distal and proximal ends of which are made in the form of a sector with a height of the radial wall of 43 mm., And the distance between the radial and arched walls equal to 43 mm., While one radial wall is absent, and inside it is arched the wall at a distance of 6 cm from the proximal edge is attached to the hook of the latch latch, and - ligature latch, consisting of a handle, a ring for a hook, a ring for ligatures.

The advantages of an anoscope for transanal excision of the rectal mucosa are as follows:

- visualization of all stages of the operation aimed at transanal excision of the rectal mucosa is possible

- during the excision of the rectal mucosa, after administration

anoscope, you can estimate the volume of prolapse of the mucosa and, accordingly, outline the volume of its resection

-Anoscope is adapted for trasanal excision of the rectal mucosa using linear staplers.

An anoscope for transanal excision of the rectal mucosa and the method of its application are presented in Figure 1. It consists of two parts; a hollow tube (1) 9 cm long. the distal and proximal ends of which are made in the form of a sector with a height of the radial wall of 43 mm. (2), and the distance between the radial and arched walls is 43 mm. (4), while one radial wall is absent (4), and inside on the arcuate wall at a distance of 6 cm from the proximal edge is attached a latch hook - ligatures (5), and the other part - a ligature latch (6), consisting of a handle ( 7), rings for the hook (8), rings for ligatures (3). After the introduction of the anoscope into the rectum, 5 cm above the dentate line, three ligatures are applied - the holders of the ends of which are inserted into the ring for the ligatures of the fixative. Using the latch handle, the ligatures together with the hook ring are fixed on the hook of the anoscope, after which the rectal mucosa is pulled to the hook by pulling at the ends of the ligatures. A linear stapler (3) with open jaws is introduced along the radial wall. After bringing the stapler to the rectal mucosa extended to the hook, it is turned clockwise, the branches are closed, stitched and the excess mucous membrane excised with a scalpel, after which the hemorrhoid is inserted into the rectum.
