Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel urethral sling for treating urinary incontinence. Background Art

[0002] With the continuous development of medical technology, the methods for treating urinary system diseases such as stress urinary incontinence are also continuously innovating and improving. Among these innovative methods, urethral slings are an important treatment device, and their research and development and application have significant practical significance in the field of urology.

[0003] Stress urinary incontinence is a common urinary system disease, especially in women. Its main symptom is the involuntary leakage of urine when coughing, sneezing, laughing or doing other activities that increase abdominal pressure. This condition seriously affects the quality of life of patients, so it is particularly important to find an effective and safe treatment.

[0004] Traditional treatments such as medication and physical therapy can relieve symptoms to a certain extent, but the long-term effect is not ideal and is prone to recurrence. Therefore, surgical treatment has become an important option. In surgical treatment, the application of urethral slings has gradually shown its unique advantages.

[0005] A urethral sling is a device specially designed to support the urethra and increase urethral tension. It is artificially implanted to form a stable support structure under the urethra, thereby effectively preventing involuntary urine outflow. Its design principle is based on human anatomy and mechanics, and it achieves stable support of the urethra by reasonably distributing the support force.

[0006] However, there are still some problems in the design and application of traditional urethral slings. For example, existing urethral slings usually adopt a single-layer mesh structure, and the mesh is a woven mesh with relatively large elasticity. When the sling is implanted in the body, the tension it provides is limited and is not enough to maintain a good lifting effect for a long time. In addition, after the existing sling is implanted, the sling is easily twisted during the removal of the protective cover, and then wound into a columnar shape. The force applied by the sling on the urethra is uneven, and a good protective effect cannot be achieved. Therefore, in-depth research and improvement are still needed to increase the tension and prevent twisting of the urethral sling. Summary of the invention

[0007] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a new urethral sling for treating urinary incontinence, so as to solve the problems of insufficient tension and easy twisting of the existing urethral sling.

[0008] To this end, the utility model proposes a new urethral sling for treating urinary incontinence, including a sling body, a double-layer widened portion in the middle of the sling body, protective sleeves are respectively provided at the left and right ends of the sling body, and puncture fixing heads are connected to the end positions of the sling body and the protective sleeve; wherein the sling body is a single-layer woven mesh structure, the double-layer widened portion is a double-layer woven mesh structure, and the front and rear sides of the double-layer widened portion are widened; at the same time, a traction rope is respectively arranged at the four corners of the double-layer widened portion, and the four traction ropes are sutured and fixed to the urethra surface, so that the double-layer widened portion is flat on the urethra surface to avoid distortion of the double-layer widened portion when the protective sleeve is removed.

[0009] As a preferred technical solution of the present invention, the distance in the length direction of the double-layer widened portion is 40 mm to 60 mm.

[0010] As a preferred technical solution of the present invention, the increased length b of the double-layer widened portion in the width direction is 2 mm.

[0011] As a preferred technical solution of the present invention, the width of the sling body is 5 to 20 mm.

[0012] As a preferred technical solution of the present invention, the traction rope is a polyethylene PE wire body, and the traction rope and the double-layer widened part are connected by hot-melt welding.

[0013] As a preferred technical solution of the present invention, the sling body and the double-layer widened portion are both polypropylene woven mesh structures.

[0014] The utility model provides a novel urethral sling for treating urinary incontinence. By widening and thickening the double-layer widened part in the middle of the sling body, the urethral urine control belt area is increased, and a stronger pulling force can be obtained at the same time. By arranging a traction rope at each of the four corners of the double-layer widened part and suturing and fixing it to the urethra surface, the sling can be prevented from twisting when the protective cover is removed, and a better supporting effect can be achieved for the urethra. In addition, the sling is made of a biocompatible material such as medical polypropylene or a synthetic polymer, and has excellent toughness and anti-degradation properties.

[0015] In summary, the urethral sling design and its use method of the patent of the present invention provide a new and effective treatment for urinary system diseases such as stress urinary incontinence, and have important clinical application value and market prospects.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] like Figure 1-2 As shown, the new urethral sling for treating urinary incontinence of the utility model comprises a sling body 1, a double-layer widened portion 2 is provided in the middle of the sling body 1, a traction rope 3 is respectively provided at the four corners of the double-layer widened portion 2, and protective sleeves 4 are respectively provided at the left and right ends of the sling body 1, and a puncture fixing head 5 is connected to the end positions of the sling body 1 and the protective sleeve 4.

[0024] Specifically, the sling body 1 is a single-layer woven mesh structure, the double-layer widened portion 2 is a double-layer woven mesh structure, and the front and rear sides of the double-layer widened portion 2 are widened; the normal width of the sling body 1 is 5-20mm; the double-layer widened portion 2 is 2mm wider on the basis of the original sling body width; the urethra control belt area is increased, and the double-layer thickening can obtain stronger tension. In addition, the length of the double-layer widened portion 2 is 40mm-60mm, which can provide better support for the urethra.

[0025] The fixed ends of the four traction ropes 3 are fixedly connected to the double-layer widened portion 2. During the process of implanting the sling for the patient, the doctor can sew and fix the four traction ropes 3 to the surface of the urethra 6. Among them, the four traction lines can prevent the sling from twisting when the protective cover is removed, so that the double-layer widened portion 2 can lay flat on the surface of the urethra 6, providing better support for the urethra. Among them, the traction rope 3 is a polyethylene PE wire body, and the traction rope 3 and the double-layer widened portion 2 are connected by hot-melt welding to form a reliable and fixed connection.

[0026] In this case, the sling body 1 and the double-layer widened portion 2 are made of materials with good biocompatibility such as polypropylene plastic or synthetic polymers, which are drawn by a plastic drawing machine, woven by a double-warp and double-weft angle wire weaving machine, and then finished by a finishing machine to form a woven mesh structure. The sling body 1 has ideal ductility and can adapt well to and increase urethral tension after being inserted into the human body, achieving the expected effect of treating urinary incontinence.

[0027] The sling is made of biocompatible materials such as medical polypropylene or synthetic polymers, and has excellent toughness and anti-degradation properties. At the same time, its design adopts a unique knotless braided structure, which allows the sling to remain flat during implantation, reducing the difficulty of surgery and improving postoperative stability.

[0028] In addition, the puncture fixing head 5 can fold the flat sling body 1 and the protective cover 4 together, which is convenient for passing through tissues during surgery and reduces the resistance of the sling when passing through.

[0029] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
