Description

Technical Field

[0001] This utility model relates to the field of stent equipment technology, and in particular to a device for preventing intrauterine adhesions. Background Technology

[0002] Intrauterine adhesions (IUA) are caused by damage to the basal layer of the endometrium, resulting in thinning or defects of the endometrium, adhesions, or fibrosis, leading to partial or complete closure of the uterine cavity. Clinical manifestations include decreased menstrual flow, amenorrhea, and infertility, severely impacting the reproductive and physical health of women of reproductive age. Patients are prone to miscarriage, premature birth, ectopic pregnancy, intrauterine fetal death, placenta accreta, placental adhesion, and even infertility. Currently, the incidence of IUA in my country is very high. Hysteroscopic surgery is a major cause of IUA; literature reports that the incidence of IUA caused by induced abortion and curettage is as high as 25%-30%, and the adhesion rate is even higher after hysteroscopy. Due to slow or poor regeneration of the endometrium after surgery, the separated uterine cavity is very prone to re-adhesion. Therefore, it is urgent to address how to reduce residual fluid in the uterine cavity, maintain a clean environment within the uterine cavity, prevent adhesions, and effectively avoid lesions and inflammation.

[0005] To overcome at least one of the defects (deficiencies) of the prior art described above, the purpose of this utility model is to provide a device for preventing intrauterine adhesions:

[0006] It includes a uterine ring and a film, the film being connected inside the uterine ring, the lower end of the uterine ring having a drainage channel, the uterine ring and the film being integrally formed, and the uterine ring having a wavy pattern.

[0007] Furthermore, the uterine ring and the film are integrally molded from medical-grade silicone.

[0011] Furthermore, the number of the cat-eye-shaped annular holes is 1 or 2.

[0012] Furthermore, the drainage channel is a multi-tiered, tree-branch shape.

[0013] Furthermore, the film is a water-resistant film.

[0015] Furthermore, it also includes thrusters.

[0016] Furthermore, the pusher includes a pusher handle and a sleeve, the sleeve being connected to the pusher handle and having a clamping port at the other end; a movable limiter is provided on the sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0047] 5. The annular hole is designed in a novel cat's-eye shape. This shape enhances the gripping force between the delivery stent and the intrauterine adhesion prevention device, ensuring stability during delivery. Simultaneously, the smaller size of the annular hole effectively reduces the contact area between tissues while maintaining drainage effectiveness, lowering the risk of tissue adhesion and facilitating rapid postoperative recovery.

[0048] 6. The surface features an advanced water-resistant film design, which prevents intrauterine fluid from accumulating on the device, allowing for smoother drainage and providing strong protection for uterine health.

[0049] Example 1

[0050] like Figure 1-3 As shown, the intrauterine adhesion prevention device of this utility model includes a uterine ring 1 and a film 4. The uterine ring is made of medical-grade silicone with a hardness of 20-30HA. A wavy design is added to the uterine ring 1 to accelerate drainage.

[0051] Thin film 4 is connected between the left and right sides of the uterine ring 1. The film 4 is laser-processed to create micro-nano structures on its surface (the laser beam is vertically focused on the sample surface, the scanning interval is 10 μm, the scanning speed is selected as 500 mm / s, and the required energy density is used for surface scanning. When the sample surface is processed with a femtosecond laser, the microtexture is prepared by filling scanning. When setting the laser scanning speed, the filling interval of the laser spot needs to be adjusted longitudinally to ensure the accuracy and quality of the microtexture). By constructing micro-nano structures and reducing surface energy on the material surface, the surface has superhydrophobic properties. When the intrauterine fluid comes into contact with the superhydrophobic surface, due to the low surface energy and special micro-nano structure, the fluid flows down the undulating waves on both sides and the top of the uterine ring 1 and onto the surface of the intrauterine adhesion prevention device. It quickly forms droplets and flows down, rolling down the "tree branch hierarchical" drainage groove 10 in stages, thereby accelerating drainage.

[0052] The membrane 4 has cat's eye-shaped holes 2 at the top and bottom. This design can effectively prevent re-adhesion of the anterior and posterior walls, lateral walls, and lateral uterine horns of the uterine cavity.

[0053] A "tree branch gradation" drainage groove 10 is provided on the tail end of the guide along its length direction, so that the liquid flowing out from the drainage groove and the liquid on the uterine ring film can be discharged.

[0054] When inserting the intrauterine adhesion prevention device, the inserting pusher acts on the upper cat-eye-shaped 2, so that the left corner of the uterine ring 1 enters the cervix first. A certain force is applied to push the pusher to separate the pusher and the intrauterine adhesion prevention device. Then, the inserting push rod acts on the lower cat-eye-shaped 2 to push the intrauterine adhesion prevention device forward as a whole, so that it reaches the uterine cavity on the other side.

[0055] Example 2

[0056] This utility model's intrauterine adhesion prevention device includes a uterine ring 1 and a film 4. The uterine ring is made of medical-grade silicone with a hardness of 20-30 HA. The uterine ring 1 features a wavy design to accelerate drainage.

[0057] The thin film 4 is connected between the left and right sides of the uterine ring 1. The thin film 4 is laser-processed to create a micro-nano structure on its surface. When the fluid flows to the surface of the uterine adhesion prevention device on both sides of the wavy pattern of the uterine ring 1 and the undulating height 31 of the wave, it will quickly form droplets and flow down, and roll down in stages along the "tree branch grading" drainage groove 10, thereby accelerating the drainage.

[0058] When inserting the intrauterine adhesion prevention device, the inserting pusher acts on the cat's eye 2 above, so that the left corner of the uterine ring 1 enters the cervix first, pushing the intrauterine adhesion prevention device forward as a whole, so that it reaches the uterine cavity on the other side, and finally a certain force is applied to push the pusher to separate the pusher and the intrauterine adhesion prevention device.

[0059] Example 3

[0060] Based on the uterine depth, adjust the movable limiter 8 of the pusher to a suitable position. When inserting the intrauterine adhesion prevention device, the insertion cannula 7 acts on the cat's eye hole 2 of the intrauterine stent, allowing the left corner of the uterine ring 1 to enter the cervix first. Apply a certain force to the pusher handle 9 to separate the pusher and the intrauterine stent device. Then, the insertion push rod acts on the lower cat's eye hole 2 to push the intrauterine adhesion prevention device forward, reaching the other side of the uterine cavity. The 4 / 3 arc design is more ergonomic, lightweight, and material-saving. The semi-concave design of the clamping port 6 better matches the cat's eye hole, ensuring a firm and stable grip during delivery, while also ensuring ease and convenience during the release of the intrauterine stent.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
