[0002] Currently in the field of human pathological pregnancy, cervical insufficiency is also known as incomplete closure of the internal cervical os and cervical relaxation. For patients with cervical insufficiency during pregnancy, it is easy to induce early pregnancy miscarriage or late pregnancy premature birth. At present, cervical cerclage has a definite therapeutic effect on such patients. Most of the commonly used cerclage methods use silk thread or coil to achieve the therapeutic purpose of tightening the cervix, but the use of silk thread and coil can easily cause cervical cutting, avulsion, or cause the cervix to relax again after the cervical edema subsides in the later stage. Some patients need a second cervical cerclage operation.

[0003] To solve this problem, a utility model patent with the authorization publication number CN202920311 U provides a cervical cerclage. The cervical cerclage provided by the utility model patent still has the following shortcomings: since the structure of the cervix is ​​similar to a trapezoidal barrel structure, which is wide at the top and narrow at the bottom, and the surface of the cervix is ​​smooth, it is easy to cause the cerclage to slip under high tension, which will affect the purpose of tightening the cervix and the treatment effect, and thus needs further improvement. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cervical cerclage device which can fix the cerclage to the cervix by suturing and fixing the suture pad and the cervix with silk thread through the suture holes preset on the suture pad on the suture fixing section of the cerclage. In this way, the cerclage is not easy to slip off and the cerclage effect is more reliable, so as to achieve the purpose of fully tightening the cervix and ensure the treatment effect.

[0006] Furthermore, there are two cerclage bands which are arranged in parallel and at intervals, and the suture pad is fixed between the two cerclage bands.

[0007] Furthermore, the spacing between the strips on the two cerclage bands is 2-4 mm.

[0008] Furthermore, the suture cushion completely covers the surface of one side of the suture fixing section for contacting with the cervix.

[0009] Furthermore, the surface of one side of the suture pad for contacting with the cervix is ​​a smooth surface.

[0010] Furthermore, the suture hole is circular in shape.

[0011] Furthermore, the width of the cerclage band is 0.6-1.2 cm, the length of the suture fixation section is 3-4 cm, and the length of the free tightening section is 2-3 cm.

[0012] Furthermore, the thickness of the sutured cushion is 1-1.5 mm.

[0013] Furthermore, the number of suture areas is 2-3.

[0014] Furthermore, the cerclage belt includes a locking head and a strip body that are integrally formed, a surface of one side of the strip body is provided with a plurality of one-way serrations, a through hole is provided in the locking head for the strip body to pass through, and a claw that matches the one-way serrations is provided in the through hole.

[0015] From the above description, it can be seen that the cervical cerclage device provided by the utility model has the following beneficial effects: by utilizing the preset suture holes of the suture pad on the suture fixing section of the cerclage band, the suture pad and the cervix are sutured and fixed with silk thread through the suture holes, thereby achieving fixation between the cerclage band and the cervix. In this way, the cerclage band is not easy to slip off, and the cerclage effect is made more reliable, thereby achieving the purpose of fully tightening the cervix and ensuring the treatment effect.

[0020] The present invention is further described below through specific implementation methods.

[0021] like Figures 1 to 3As shown, a cervical cerclage device described in the utility model comprises a cerclage belt 1, and a suture fixing section 121 and a free tightening section 122 are provided on the strip body 12 of the cerclage belt 1 in sequence from one end close to the locking head 11 to the other end, and a suture pad 2 is fixed on the suture fixing section 121, and a plurality of suture areas 21 arranged at intervals are provided on the suture pad 2 along its length direction, and two suture holes 211 arranged at intervals are provided in the suture area 21, and the suture holes 211 are used for passing silk thread to suture and fix the suture pad 2 to the cervix.

[0022] During suturing and fixation, a suture needle is used to pass a silk thread through a suture hole 211 and then suture it to the cervix. After the needle is removed from the cervix, the thread is passed through another suture hole 211. Then, both ends of the silk thread are knotted to achieve suturing and fixation between the suture cushion 2 and the cervix, thereby achieving fixation between the cerclage band 1 and the cervix. In this way, the cerclage band 1 is not easy to slip off, and the cerclage effect is more reliable, thereby achieving the purpose of fully tightening the cervix and ensuring the treatment effect. In addition, by adopting the cerclage band 1 with an adjustable tightening function, the cerclage band 1 can be tightened again after it is loosened due to the subsidence of cervical edema in the later stage, thereby avoiding a secondary cerclage surgery caused by the loosening of the cervix after the cerclage surgery.

[0023] The two cerclage bands 1 are arranged in parallel and at intervals. By using two of the cerclage bands 1, compared with one of the cerclage bands 1, it can enhance the tightening effect and make the cervical contraction more firm and reliable. The suture pad 2 is fixed between the two cerclage bands 1. The spacing between the strip belt bodies 12 on the two cerclage bands 1 is 2-4mm. The suture pad 2 completely covers the side surface of the suture fixing section 121 used to abut against the cervix, thereby increasing the tightening contact area between the suture pad 2 and the cervix, not easily causing cervical cutting, and having a better tightening effect. At this time, the suture hole 211 is located on the suture pad 2 between the two cerclage bands 1. The side surface of the suture pad 2 used to abut against the cervix is ​​a smooth surface, which effectively reduces the friction between the suture pad 2 and the cervix, thereby reducing the risk of infection and erosion of cervical tissue due to long-term friction. In addition, the suture pad 2 can be made of medical silicone material.

[0024] The width of the cerclage band 1 is 0.6-1.2 cm, the length of the suture fixing section 121 is 3-4 cm, and accordingly, the length of the suture fixing section 121 can be 3 cm, 3.5 cm or 4 cm. The length of the suture fixing section 121 is smaller than the circumference of the cervix, the length of the free tightening section 122 is 2-3 cm, and the thickness of the suture pad 2 is 1-1.5 mm.

[0025] The number of the suture areas 21 is 2-3, so that the suture pad 2 and the cervix can be sutured and fixed at 2-3 locations, and the suture holes 211 are circular.

[0026] The ferrule strap 1 includes the locking head 11 and the strip body 12 which are integrally formed. A plurality of one-way serrations 123 are provided on one side surface of the strip body 12. A through hole 111 is provided in the locking head 11 for the strip body 12 to pass through. A claw 112 which is adapted to the one-way serrations 123 is provided in the through hole 111. Since the ferrule strap 1 can adopt the structure of the prior art, no further details are given here.

[0027] The method of using the cervical cerclage device described in the utility model is as follows: when using the cerclage device, after placing the cerclage device at the corresponding position of the cervix, a suture needle can be used to pass a silk thread through a suture hole 211 and then suture the cervix, and then pass the needle through another suture hole 211 after exiting the cervix, thereby sequentially suturing the multiple suture areas 21 on the suture cushion 2 and the cervix, and after one end of the free tightening section 122 of the cerclage band 1 passes through the through hole 111 of the locking head 11, by tightening the free tightening section 122 of the cerclage band 1 The unidirectional sawtooth 123 is clamped at one end with the clamping claw 112 to tighten the cervix, and then the two ends of the silk thread are knotted to achieve the suturing and fixation between the suture cushion 2 and the cervix, so as to achieve the suturing and fixation between the cerclage band 1 and the cervix, thereby making it difficult for the cerclage band 1 to slip off. In addition, when the cerclage band 1 becomes loose due to the subsidence of cervical edema in the later stage, the free tightening section 122 of the cerclage band 1 can be continuously tightened to continue tightening the cerclage band 1 to further tighten the cervix.

[0028] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
