Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a postoperatively adjustable device for treating female stress urinary incontinence. Background Art

[0002] Polypropylene synthetic sling is an important product for the treatment of stress urinary incontinence. It restricts the mobility of the middle part of the female urethra, thereby solving the symptoms of stress urinary incontinence. It is currently the main method for treating stress urinary incontinence. However, the current problem is that once the sling is implanted, it cannot be adjusted after surgery, and the treatment effect cannot be achieved. If a good treatment effect is required, the surgical operator is required to accurately control the position, tightness and cutting length of the sling. In actual surgery, this is very difficult, and some patients even need a second surgery. This product is designed so that patients can adjust the tightness of the sling a second time in a short period of time, making the surgical results more reliable and achieving the best treatment effect. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies of the prior art, the present invention provides an adjustable postoperative device for treating female stress urinary incontinence, which solves the problem that the sling currently in use is not convenient to adjust the degree of pressure of the sling on the urethra according to the patient's recovery condition during the postoperative patient recovery period.

[0028] See also Figure 1-4 The present invention provides a new technical solution: a postoperative adjustable device for treating female stress urinary incontinence, comprising a compression belt 1, which is in the shape of a long strip as a whole. The compression belt 1 is specifically a mesh sling or a yarn sling, and its material includes but is not limited to polypropylene. The two ends of the compression belt 1 are arc-shaped and contracted to form a contraction section 5, and its contraction direction is toward the same side of the compression belt 1, so that the width of the end of the compression belt 1 is smaller than the width of the middle. The compression belt 1 is provided with a tensioning line 2 extending along its length direction, and the tensioning line 2 is located on the midline of the width of the compression belt 1, and the total length of the tensioning line 2 is greater than the total length of the compression belt 1.

[0029] In some embodiments, the width of the compression belt 1 is 0.5cm-1.5cm, and in this embodiment, the width of the compression belt 1 is 1cm; the compression belt 1 has a point X and a point Y at both ends, respectively. In the present invention, the compression belt 1 shrinks from point X and point Y to the outer end to form a shrinkage section 5. In some embodiments, the length of the shrinkage section 5 is 1-1.5cm, the width of the shrinkage section 5 is 1 / 3-1 / 2 of the total width of the compression belt 1, and the length distance between point X and point Y is 40-50cm; in the embodiment, the length of the shrinkage section 5 is 1cm, the width of the shrinkage section 5 is 1 / 2 of the total width of the compression belt 1, and the shrinkage method is to shrink from one side of the width of the compression belt 1 to the other side until a semicircular end is left at the end of the compression belt 1, and the length distance between point X and point Y is 45cm.

[0030] In the present invention, along the length direction of the compression belt 1, from left to right, there are point c, point a2, point a1, point O, point b, and point d; wherein point O is the physical midpoint of the length direction of the compression belt 1, point a1 is located on the left side of point O, and the distance between point a1 and point O is 1.5 cm, point a2 and point b are located on both sides of point O, respectively, and are symmetrically arranged with point a2 and point b about point O, and the distance between point a2 and point b and point O is 5 cm, wherein point c and point d are both located in the middle position of the end of the length of the compression belt 1, and the tensioning line 2 passes through point c, point a2, point a1, point O, point b, and point d in sequence, and is fixedly connected with them, and the fixing method includes but is not limited to the tensioning line 2 and the compression belt 1 being knotted and fixed, and the tensioning line 2 and the compression belt 1 can also be integrally formed or bonded, so that the compression belt 1 is implanted in the human body, and the tensioning line 2 at the end can be used to pull the compression belt 1 located inside the human body, and the compression belt 1 located inside the human body can be tensioned to make the compression degree of the human urethra 4 tighter;

[0031] In addition, a release line 3 is provided at a1, and the length of the release line 3 is 6-8 cm. In the present embodiment, the length of the release line 3 is 7 cm, and the release line 3 is suspended on the tensioning line 2, or the release line 3 is knotted and fixed with the tensioning line 2 at a1; or the release line 3 is looped on the tensioning line 2; or the release line 3 is sutured to the compression belt 1 and wrapped around the tensioning line 2; in this way, when the compression belt 1 in the human body compresses the urethra 4 too tightly, the release line 3 can be pulled outward to relax the compression degree of the compression belt 1 on the human urethra 4, so that the compression degree of the urethra 4 of the patient with stress urinary incontinence can be conveniently adjusted after surgery, which is more beneficial to the patient's rehabilitation and makes the postoperative recovery effect better.

[0032] The material of the tensioning wire 2 is absorbable wire.

[0033] When in use, the compression belt 1 is implanted in the human body, and the physical midpoint of the compression belt 1 (that is, point O) is located below the human urethra 4. Then, the two ends of the compression belt 1 that are too long are cut off. It is worth noting that the cutting position is located between point c and point a2 and between point b and point d, and only the compression belt 1 is cut off, and the two ends of the tension line 2 are still located outside the body, and then the wound is sutured; in this way, during the recovery period, if the compression belt 1 is too tight on the urethra 4, the point a1 can be pulled outward through the relaxation line 3. At this time, the tension of the relaxation line 3 acts on points a2 and b through the tension line 2, so that the pressure of the compression belt 1 on the urethra 4 is relaxed; if the pressure of the compression belt 1 on the human urethra 4 is too relaxed, the tension line 2 or the end of the contraction section 5 can be pulled outside the human body, and the compression belt 1 can be tightened in the patient's body through the close combination of the tension line 2 and the compression belt 1 at point a2 or point b, so that the compression belt 1 can be tightened on the urethra 4. This can increase the degree of compression of the compression belt 1 on the urethra 4. It is achieved by adjusting the compression force after surgery to facilitate better recovery of patients.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
