Description

TECHNICAL FIELD

[0001] The utility model relates to an anoscope technical field, concretely relates to an anoscope for anal fistula treatment. BACKGROUND

[0002] In the treatment of anorectal diseases, an anoscope is often used, which is used for checking anorectum.

[0003] An anal fistula is an abnormal duct and cavity formed between the rectum or anus and the external opening, which is a common intractable disease in the anorectal department. The pathogenesis of the disease mainly has three kinds of anal crypt infection theory, central space infection theory and epithelial cell disease theory. Most scholars accept the anal crypt infection theory, considering that the main reason for the repeated attack and long-term non-healing of anal fistula is the existence of internal opening and infected anal glands. Therefore, completely eliminating the primary infection focus and correctly handling the primary internal opening are the key to the success of anal fistula treatment, among which whether the position of the internal opening can be quickly found affects the progress of treatment and patient comfort.

[0004] According to the investigation, the Chinese utility model patent (patent No. CN211130986U) with the application No. CN201921130682.2 discloses an exposed type anti-falling side opening anoscope, which comprises a tube body and a handle arranged at the tail end of the tube body, the front end of the tube body is provided with a conical head, one side of the tube body is provided with a side opening, the side opening is formed by a side cutting wall at a certain angle with the axis of the tube body, and the front end opening size of the side opening is smaller than the tail end opening size of the side opening; the front end of the side opening extends to the head of the conical head along the side wall of the conical head.

[0005] The anoscope in the above-mentioned patent is mainly suitable for checking other anorectal diseases, although it can also be used to find the internal opening to a certain extent, but the internal skin corresponding to the patient's anal fistula still cannot be fully unfolded, so that the above-mentioned anoscope cannot be well applied to the treatment of anal fistula, and the internal skin near the internal opening of the patient may be stacked, and sometimes the position of the internal opening is far away from the anus, so that the internal opening is not easy to be quickly found. Therefore, it is necessary to design an anoscope for anal fistula treatment which is convenient for quickly finding the internal opening. UTILITY MODEL CONTENTS

[0006] The technical problem to be solved by the utility model is to provide an anoscope for anal fistula treatment which is convenient for quickly finding the internal opening according to the status of the prior art.

[0007] The utility model adopts the technical scheme that: an anoscope for anal fistula treatment, comprising

[0008] The mirror barrel extends up and down, the mirror barrel has a containing space extending up and down, and the barrel wall of the mirror barrel is provided with an opening communicating with the containing space and extending up and down;

[0009] Characterized in that:

[0010] The two extension parts extend from the two side walls of the opening to the outside of the lens barrel, and the two extension parts gradually move away from each other from the end close to the lens barrel to the end far from the lens barrel, and are trumpet-shaped.

[0011] In order to prevent the internal skin of the patient from being damaged, the lower end of the extension part is arc-shaped. The arc-shaped part is not sharp, so as to prevent the internal skin of the patient from being damaged.

[0012] In order to prevent the internal skin of the patient from being damaged, the lens barrel and the extension part are smoothly connected. The smoothly connected part is not sharp, so as to prevent the internal skin of the patient from being damaged.

[0013] In order to meet the requirements of fully expanding the internal skin of the patient and the comfort of the patient, the included angle between the two extension parts is 35-45 degrees. If the included angle is too small, the internal skin of the patient cannot be well expanded; if the included angle is too large, the patient is easily uncomfortable.

[0014] In order to facilitate the insertion of the anoscope, the lower end of the lens barrel is provided with a sharp corner part, and the sharp corner part has an opening aligned with and communicated with the opening of the lens barrel.

[0015] The position of the extension part is higher than that of the sharp corner part.

[0016] In order to facilitate the doctor to take the anoscope, a handle is arranged at the upper end of the outer wall of the lens barrel, and the handle is connected with the upper end of the corresponding extension part. The handle is arranged to facilitate the doctor to take the anoscope, and medical adhesive tape is pasted on the handle to facilitate the positioning of the anoscope.

[0017] Preferably, the handle has two, and is connected with the upper end of the corresponding extension part.

[0018] In order to prevent slipping, the handle has anti-slip lines.

[0019] In order to facilitate the doctor to observe, the lens barrel and the extension part are made of transparent material.

[0020] In order to reduce the assembly process, the anoscope is integrally formed.

[0021] Compared with the prior art, the anoscope has the advantages that: the extension part is arranged on the lens barrel, the two extension parts move away from each other and are trumpet-shaped, so as to facilitate the expansion of the internal skin of the patient through the extension part, and the anoscope can be supported and prevented from slipping, even if the position of the inner opening is far away from the anus opening, the doctor can also observe and quickly find the inner opening, so as to speed up the treatment progress of the anal fistula and improve the comfort of the patient.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1 to 4 This is a preferred embodiment of the present invention. The anoscope for treating anal fistula includes a barrel 1, an extension 2, a pointed end 3, and a handle 4.

[0028] The microscope tube 1 extends vertically and has a through-hole 12. The tube wall of the microscope tube 1 has an opening 11 that is connected to and extends vertically through the through-hole 12.

[0029] There are two extensions 2, each extending outward from the side walls of the opening 11 towards the lens barrel 1. The two extensions 2 gradually move away from each other from the end closer to the lens barrel 1, forming a trumpet shape. The lower end 2a of the extension 2 is arc-shaped. There is a smooth transition between the lens barrel 1 and the extensions 2. See [reference needed] Figure 4 The included angle between the two extensions 2 is denoted as α, which is 35 to 45 degrees, preferably 45 degrees. The position of the extension 2 is higher than that of the pointed corner 3.

[0030] The pointed end 3 is located at the lower end of the lens barrel 1, and the pointed end 3 has an opening 31 that is vertically aligned with and communicates with the opening 11.

[0031] A handle 4 is located on the upper part of the outer wall of the lens barrel 1, and the handle 4 is connected to the upper end of the corresponding extension 2. There are two handles 4, each connected to the upper end of the corresponding extension 2. The handle 4 may be provided with anti-slip texture, such as horizontal stripes or diamond patterns.

[0032] The endoscope tube 1, extension 2, and handle 4 are all made of transparent material, such as transparent plastic. The anoscope is molded as a single piece.

[0033] The working principle and usage process are as follows.

[0034] The anoscope is inserted into the patient's anus. The extension part 2 facilitates the full unfolding of the patient's internal skin. The position of the endoscope tube 1 and the extension part 2 can be adjusted by rotating the handle 4. The handle 4 is fixed to the patient's external skin with medical tape.

[0035] This allows doctors to quickly locate the internal opening under the guidance of an anoscope, and then determine the depth and direction of the fistula based on the internal opening, so that they can subsequently squeeze out the pus, remove the necrotic tissue in the fistula, and perform seton treatment.
