Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable anoscope. Background Technology

[0002] As is well known, an anoscope is an instrument used to examine anorectal lesions and is used very frequently in anorectal examinations. When using a current anoscope, the anal margin is generally massaged with lubricant applied to the end of the endcap to relax the sphincter. Then, the endoscope and endcap are slowly pushed into the anal canal. Once fully inserted, the endcap is removed, and the anorectal area can then be examined through the endoscope.

[0003] However, in actual examinations, problems often arise such as the anoscope being too small, the anal opening being too low, and the doctor having difficulty observing, making it difficult to achieve the desired results with an anoscope. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable anoscope, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustable anoscope, including a fixed cylinder with an opening at the top, an external threaded tube fixedly connected to the middle of the bottom wall inside the fixed cylinder, and the bottom wall communicating with the external threaded tube, a plurality of sliding holes evenly distributed around the external threaded tube on the bottom wall of the fixed cylinder, an expansion component installed on each sliding hole, a push tube threadedly connected to the external threaded tube, the push tube rotating on the external threaded tube, thereby pushing the expansion component to move in the sliding hole.

[0008] Furthermore, the outer side of the push tube is tapered.

[0009] Furthermore, a rotating handle is fixedly connected to the top of the push tube.

[0010] Furthermore, the expansion assembly includes an expansion piece, a sliding plate, and a connecting block. One end of the connecting block is fixedly connected to the expansion piece, and the other end is fixedly connected to the sliding plate. The connecting block and the sliding hole are slidably connected.

[0011] Furthermore, when adjacent expansion plates come into contact, they form a cylindrical shape.

[0012] Furthermore, the expansion sheet is made of a transparent material.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an adjustable anoscope, which has the following beneficial effects:

[0015] This adjustable anoscope, by rotating the handle, causes the push tube to rotate on the external threaded tube. The outer wall of the external threaded tube is conical, which can push the sliding plate to move along the sliding hole, and at the same time drive the dilator to gradually expand outward, so that it can be stretched according to the size of the anus, so that the doctor can examine the inside of the anus.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention discloses an adjustable anoscope, comprising a fixed cylinder 1 with an opening at the top. An externally threaded tube 2 is fixedly connected to the middle of the bottom wall inside the fixed cylinder 1, and the bottom wall is connected to the externally threaded tube 2. Multiple sliding holes 6 are evenly distributed around the externally threaded tube 2 on the bottom wall of the fixed cylinder 1, and an expansion component is installed on each sliding hole 6. A push tube 3 is threadedly connected to the externally threaded tube 2. The push tube 3 rotates on the externally threaded tube 2, thereby pushing the expansion component to move in the sliding hole 6 to dilate the patient's anus.

[0023] The outer side of the push tube 3 is tapered, which allows the push tube 3 to rotate on the external threaded tube 2 and gradually push the sliding plate 5 downward.

[0024] The expansion assembly includes an expansion plate 4, a sliding plate 5, and a connecting block 8. One end of the connecting block 8 is fixedly connected to the expansion plate 4, and the other end is fixedly connected to the sliding plate 5. The connecting block 8 is slidably connected to the sliding hole 6. The expansion plate 4 is placed outside the fixed cylinder 1, and the sliding plate 5 is placed inside the fixed cylinder 1. The surface of the sliding plate 5 that contacts the external threaded pipe 2 is set as an arc-shaped surface, so that when the push tube 3 moves downward, it enters between the sliding plate 5 and the external threaded pipe 2.

[0025] The top of the push tube 3 is fixedly connected to a handle 7. The side wall of the handle 7 is provided with multiple equal surfaces, which makes it easier for medical personnel to increase the friction with their hands when rotating the handle 7, and prevent their hands from slipping.

[0026] When adjacent expansion pieces 4 come into contact, they form a cylindrical shape, which facilitates inserting the front part of the expansion piece into the anus and being squeezed by the anus.

[0027] The dilator 4 is made of transparent material so that the doctor can examine the anus after it has been dilated.

[0028] In summary, when using this adjustable anoscope, the doctor applies lubricant to the outer wall of each dilator 4, forms an annular hole with the index finger and thumb, and the dilators 4 are brought into contact with each other through the annular hole formed by the fingers. Then, the other hand pushes the handle 7 to insert the dilator 4 into the patient's anus. The hand that formed the annular hole is then removed, and the doctor holds the fixing tube 1 with the other hand while rotating the handle 7, causing the push tube 3 to rotate in the external threaded tube 2. This causes the push tube 3 to gradually push the sliding plate 5, causing the dilator 4 to slide along the sliding hole 6. At the same time, the anus is opened according to the diameter of the patient's anus so that the doctor can examine the anus.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
