[0002] An anorectal dilator is a medical device specifically used for anorectal examinations and treatments. For some anorectal diseases, self - use of a dilator at home for anal dilation is an important part of the treatment and rehabilitation process. Currently, commonly used dilators usually include a dilation part and a handle. The dilation part is the component that directly contacts the anus and performs dilation, and the handle is used to facilitate the operation of medical staff and control the insertion depth and angle of the dilator. However, in actual use, due to differences in the hand strength and perception ability of different patients, the dilator may be inserted too deep or too shallow, and it is impossible to ensure the insertion depth. If the dilator is inserted too deep, it will stimulate the intestine and damage the intestinal mucosa. On the contrary, if the dilator is inserted too shallow, the expected treatment effect may not be achieved.

[0003] In order to overcome the deficiencies and defects in the background art, the utility model provides an anorectal dilator. Summary of the Utility Model

[0032] As Figures 1 to 6 shown, an anorectal dilator includes a dilator base 1, a dilator main body 2, and a retaining ring 3. The dilator main body 2 is arranged at one end of the dilator base 1. The dilator main body 2 is successively provided with a non-dilation part 2221 and a dilation part 22 in the direction extending from one end of the dilator base 1 to the other end. The outer surface axial diameter of the dilation part 22 gradually decreases along its axial direction from one end of the dilator base 1 to the other end. The retaining ring 3 is detachably installed on the dilator main body 2, and the retaining ring 3 is configured to be able to move on the non-dilation part 2221.

[0033] In this embodiment, first, the dilator base 1 provides a stable foundation and an operating support for the entire device; then, the design of the outer surface axial diameter of the dilation part 22 of the dilator main body 2 gradually decreasing can achieve a gradual and uniform dilation effect, which helps to reduce the sudden stimulation and damage to the anal tissue; then, the retaining ring 3 has the advantages of adjustability and safety. It can flexibly adjust the position of the retaining ring 3 according to different treatment requirements and patient conditions, control the depth of dilation, and prevent the dilator from being inserted excessively, playing a certain protective role. For example, for patients with more severe conditions and requiring a greater degree of dilation, the retaining ring 3 can be set at a position closer to the dilator base 1; while for patients with milder conditions and requiring a smaller degree of dilation, the retaining ring 3 can be appropriately moved towards the other end.

[0034] The present utility model installs a retaining ring 3 with an adjustable position on the dilator main body 2, which can flexibly adjust the position of the retaining ring 3 according to the specific conditions of the patient. When the patient pushes the dilator to the position of the retaining ring 3, it means that the safe and effective depth has been reached. It provides a clear and intuitive stop signal for the patient. The patient does not need to rely on their own feelings or experience to judge whether the depth is appropriate, and only needs to stop pushing when touching the retaining ring 3, greatly reducing the operation difficulty and uncertainty to achieve precise treatment.

[0035] In this embodiment, the above-mentioned retaining ring 3 includes a connecting pipe 31 and a flange 32 provided at one end of the connecting pipe 31. The connecting pipe 31 is detachably installed on the anal dilator main body 2, and the connecting pipe 31 is configured to be movable on the non-dilation part 2221. First of all, the design of the flange 32 can play a role of blocking and restricting. That is, when the patient pushes the anal dilator to the position of the retaining ring 3, it means that the safe and effective depth has been reached, which provides a clear and intuitive stop signal for the patient. Then, the connecting pipe 31 is detachably installed on the anal dilator main body 2 and can move on the non-dilation part 2221. Such a design facilitates the installation and disassembly of the retaining ring 3 on the one hand, making the preparation before use and the cleaning and disinfection work after use more convenient. On the other hand, the characteristic of freely moving on the non-dilation part 2221 increases the flexibility of use. Doctors or patients can precisely adjust the position of the retaining ring 3 according to specific treatment needs to achieve the best anal dilation effect. For example, during the treatment process, if it is necessary to gradually increase the depth of anal dilation, the retaining ring 3 can be gradually moved towards the anal dilator base 1.

[0036] Furthermore, an internal thread 311 is provided on the inner wall of the above-mentioned connecting pipe 31, and an external thread 211 that cooperates with the internal thread 311 is provided on the outer surface of the non-dilation part 2221 along its axial direction from the end of the anal dilator base 1 to the other end. First of all, the threaded connection is relatively stable and can withstand a certain amount of thrust and tension to ensure that the retaining ring 3 will not shift easily during use. Secondly, the installation and position adjustment by rotation are relatively precise, and the position of the retaining ring 3 can be more finely controlled to meet the needs of different patients. In addition, this connection method is also relatively easy to implement in terms of manufacturing and processing, and the cost is relatively low.

[0037] In this embodiment, a scale 4 is provided on the outer surface of the dilation part 22. The presence of the scale 4 provides a clear and definite reference standard for the patient. The patient can directly adjust the position of the retaining ring 3 according to the scale 4, so as to meet the fine control requirements for the depth of anal dilation, greatly improving the accuracy and safety of the operation.

[0038] In this embodiment, the above-mentioned anal dilator main body 2 and the anal dilator base 1 are integrally formed. The integrated design reduces the possible weak points at the connection part, makes the whole anal dilator more durable, simplifies the production process, reduces the production cost, and at the same time is easier to ensure the quality consistency of the product.

[0039] In this embodiment, the anorectal dilator also includes a handle 5, and the outer circle of the dilator seat 1 is provided with the handle 5. First, it is convenient for the operator to control the insertion direction and depth of the dilator more easily by holding the handle 5, thereby improving the accuracy and stability of the operation. Secondly, the comfort of the operation is increased. The handle 5 provides a better holding position, reducing the discomfort that may be caused by direct contact with the dilator seat 1. Furthermore, the operator can operate the dilator through the handle 5, reducing the risk of contamination that may be caused by direct contact with other parts of the dilator. For example, when performing an anal dilation operation, the operator can control the angle and speed of the dilator more accurately through the handle 5.

[0040] Preferably, the handle 5 and the anal dilator seat 1 are integrally formed, and the integral structure avoids possible loosening or breakage of the connection part, so that the handle 5 can withstand greater force when in use and is not easily damaged, thereby reducing the process of assembling the handle 5, reducing the complexity and cost of production, and making the appearance more simple and beautiful. It can also provide a smoother operating experience when in use, and the feel will not be affected by gaps or unevenness at the connection. It has the advantages of high strength, simple manufacture and good integrity.

[0041] In this embodiment, the anorectal dilator also includes a core 6, a cavity 24 is provided inside the dilator body 2, both ends of the dilator body 2 have openings 23 connected to the cavity 24, the dilator seat 1 has a through hole 11 connected to the opening 23, the core 6 is detachably inserted into the cavity 24 of the dilator body 2, wherein a pressing portion 62 is provided at one end of the core 6, and a protrusion 61 is provided at the other end of the core 6, the protrusion 61 passes through the cavity 24 of the dilator body 2 and is exposed from the opening 23, and the end of the protrusion 61 facing away from the dilator body 2 is arc-shaped.

[0042] In actual use, the retaining ring 3 is first installed on the anal dilator body 2, and the position of the retaining ring 3 is adjusted according to the scale 4, and then the core 6 is inserted into the cavity 24 of the anal dilator body 2, so that the arc-shaped protrusion 61 of the core 6 leaks out from the opening 23 of the anal dilator body 2, and then the handle 5 is held and the pressing part 62 of the core 6 is pressed, so that the expansion part 22 of the anal dilator body 2 is sequentially inserted into the anus. This embodiment can better control the insertion depth and strength of the anal dilator through the position adjustment of the retaining ring 3 and the auxiliary insertion of the core 6, and reduce the risk of accidental damage to the anal tissue.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
