Description

Technical Field

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

[0002] Intrauterine adhesions are usually caused by endometrial damage due to intrauterine procedures, radiation exposure, gynecological infections, and other factors. Currently, clinical methods to prevent re-adhesion mainly include drug therapy, physical barrier methods, and endometrial stem cell therapy. Among these, physical barrier methods use mechanical dispersing to fully open the uterine cavity wall, thereby reducing the adhesion of the endometrium to each other during the healing process of fresh wounds, maintaining the shape and normal physiological function of the uterine cavity. Currently, the physical barrier measures used clinically mainly include intrauterine device (IUD) placement, Foley balloon catheter dilation, the use of isolation materials and biological agents, and triangular balloon stents.

[0003] A balloon uterine stent for preventing intrauterine adhesions, with publication number CN111420246B, includes a triangular balloon stent, a catheter, a one-way valve, and a drainage chamber.

[0004] The aforementioned device can greatly improve the anti-adhesion effect of the intrauterine anti-adhesion balloon stent. However, the triangular side of the balloon stent in the aforementioned device is relatively large, making it difficult to insert into the uterus. Consequently, it not only causes significant discomfort to the patient during insertion but also affects the placement efficiency of the balloon stent. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the triangular side of the existing balloon stent is too large, making it difficult to insert into the uterus, and to propose a uterine stent that prevents intrauterine adhesions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A uterine stent for preventing intrauterine adhesions includes a balloon stent and an infusion tubing. The balloon stent has an integrally formed connecting tube and two plastic retaining rings. One end of the infusion tubing is fixedly connected to the connecting tube, and a one-way valve is installed on the infusion tubing.

[0008] The infusion tubing is provided with an external pushing mechanism, which includes a push cylinder. A right-angle rod is fixedly connected to the outer surface of the push cylinder, and a support rod is fixedly connected to the other end of the right-angle rod. Both ends of the support rod are fixedly connected to plastic hooks, and a clamping assembly is provided on the push cylinder.

[0009] Preferably, the clamping assembly includes two operating rings, both of which are located inside the push cylinder. Two guide rods are fixedly connected to the opposite sides of the two operating rings. Four support cylinders are fixedly connected to the outer surface of the push cylinder. The end of the guide rod away from the operating ring slides through the push cylinder and extends into the interior of the support cylinder.

[0010] Preferably, each of the four guide rods has a spring fixedly connected to one end away from the operating ring, and the other end of each of the four springs is fixedly connected to the inner wall of one of the four support cylinders.

[0011] Preferably, the clamping assembly further includes two toothed rings, both of which are located inside the push cylinder, and the toothed rings and the operating ring are connected by multiple connecting rods.

[0012] Preferably, the sides of the two toothed rings near the balloon support are flush with the end of the push tube near the balloon support, and the two toothed rings are clamped on the connecting tube.

[0013] Preferably, the side of each of the two operating rings away from the balloon support is flush with the end of the push tube away from the balloon support.

[0014] Compared with the prior art, this utility model provides a uterine stent for preventing intrauterine adhesions, which has the following beneficial effects:

[0015] This invention, by installing an insertion mechanism on a balloon stent, allows for the insertion of the balloon stent into the patient's uterus. First, the balloon stent is folded into a long strip, and its plastic retainer is hooked onto the plastic hook of the insertion mechanism. Then, the balloon stent is inserted into the uterus by pushing the insertion tube. Afterward, saline or other fluids are introduced into the balloon stent through an infusion tubing, causing it to inflate and fully expand the uterine cavity wall, preventing intrauterine adhesions. During the inflation process, the plastic retainer automatically detaches from the plastic hook, allowing the insertion tube to be easily removed from the balloon stent, thus completing the installation. This effectively solves the technical problem of existing balloon stents being difficult to insert into the patient's uterus. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A uterine stent for preventing intrauterine adhesions includes a balloon stent 1 and an infusion tubing 2. The balloon stent 1 has an integrally formed connecting tube 4 and two plastic retaining rings 15. One end of the infusion tubing 2 is fixedly connected to the connecting tube 4. A one-way valve 3 is installed on the infusion tubing 2, which allows saline or other liquids to be introduced into the interior of the balloon stent 1. By setting the one-way valve 3, it is ensured that the liquid can only flow into the interior of the balloon stent 1 through the infusion tubing 2 and will not flow back out of the balloon stent 1.

[0025] An insertion mechanism is provided on the outside of the infusion tubing 2. The insertion mechanism includes a pusher 5, on the outer surface of which a right-angle rod 12 is fixedly connected. A support rod 13 is fixedly connected to the other end of the right-angle rod 12. Plastic hooks 14 are fixedly connected to both ends of the support rod 13. When the balloon stent 1 is inserted into the patient's uterus, the balloon stent 1 is first folded into a long strip and the plastic retainer 15 on the balloon stent 1 is hung on the plastic hooks 14 of the insertion mechanism. Then, the balloon stent 1 can be inserted into the uterus by pushing the pusher 5. After that, normal saline is introduced into the balloon stent 1 through the infusion tubing 2. The balloon stent 1 expands due to the fluid, which fully expands the uterine cavity wall and prevents intrauterine adhesions. During the expansion of the balloon stent 1, the plastic retainer 15 automatically detaches from the plastic hook 14, and then the pusher 5 can be removed from the balloon stent 1 to complete the installation of the balloon stent 1. This effectively solves the technical problem that the existing balloon stent 1 is not easy to insert into the patient's uterus. By making the plastic hook 14 and plastic retainer 15 out of plastic, the plastic's deformability can be utilized to make the plastic retainer 15 detach from the plastic hook 14 more smoothly when the balloon stent 1 expands.

[0026] The push cylinder 5 is equipped with a clamping assembly, which includes two operating rings 7. Both operating rings 7 are located inside the push cylinder 5. Two guide rods 9 are fixedly connected to the side of the two operating rings 7 that are far apart from each other. Four support cylinders 10 are fixedly connected to the outer surface of the push cylinder 5. The end of the guide rod 9 that is far away from the operating ring 7 slides through the push cylinder 5 and extends into the interior of the support cylinder 10. The inside of the push cylinder 5 is provided with a round hole that matches the guide rod 9.

[0027] Each of the four guide rods 9 has a spring 11 fixedly connected to one end away from the operating ring 7. The other ends of the four springs 11 are fixedly connected to the inner walls of the four support cylinders 10 respectively. The side of the two operating rings 7 away from the balloon support 1 is flush with the end of the push cylinder 5 away from the balloon support 1. When the operating ring 7 moves outward, it will compress the spring 11.

[0028] The clamping assembly also includes two toothed rings 6, both located inside the push tube 5. The toothed rings 6 and the operating rings 7 are connected by multiple connecting rods 8. The sides of the two toothed rings 6 near the balloon support 1 are flush with the ends of the push tube 5 near the balloon support 1, and the two toothed rings 6 are clamped on the connecting tube 4. When installing the push tube 5, first pull the two operating rings 7 outward. The operating rings 7 can drive the toothed rings 6 to move outward and compress the spring 11. Then, put the push tube 5 on the outside of the infusion tubing 2 and make one end of the push tube 5 abut against the balloon support 1. Then release the two operating rings 7. Under the action of the guide rod 9, the operating rings 7 and the toothed rings 6 will move inward, so that the two toothed rings 6 will clamp on the connecting tube 4. At this time, the installation of the push tube 5 is completed. Then, the balloon support 1 is folded into a long strip and the plastic retainer 15 is hung on the plastic hook 14. Then, the balloon support 1 can be inserted into the uterus by pushing the push tube 5.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
