Description

Technical Field

[0001] This utility model relates to a medical device, and more particularly to a cervical cerclage band for transabdominal cervical cerclage. Background Technology

[0002] Cervical insufficiency, also known as cervical dysfunction, is a common pregnancy-related disease. The main clinical treatment is cervical cerclage, which is divided into transvaginal cervical cerclage and transabdominal cervical cerclage. Laparoscopic cervical cerclage is the preferred method for transabdominal cerclage due to its advantages such as minimal invasiveness (Li Sifan. Efficacy analysis of different cervical cerclage pathways in the treatment of twin pregnancy complicated with cervical insufficiency [J]. Chinese Journal of Minimally Invasive Surgery, 2025, 25(03): 164-170.).

[0003] Currently, the cervical cerclage band commonly used in cervical cerclage consists of suture needles and suture bands, with curved suture needles located at both ends of the suture band (CN 2243269Y). This type of cerclage band is suitable for transvaginal cervical cerclage but not for transabdominal cervical cerclage. Utility model patent applications with publication numbers CN 208973956 U and CN 215534903 U disclose cerclage bands suitable for transabdominal cervical cerclage, using straight needles instead of curved needles at the ends of the sutures / bands, reducing the need for manually straightening the suture needles and making laparoscopic cervical cerclage slightly faster. However, both of these cerclage bands are not conducive to post-operative procedures. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a cervical ligation band for transabdominal cervical ligation to facilitate postoperative procedures.

[0005] Technical solution: The present invention provides a cervical cerclage band for transabdominal cervical cerclage, comprising a suture band and a suture needle. The suture needle is a straight needle connected to both ends of the suture band. The suture band is a flat strip, and one end of the suture band has a slit through which the remaining end of the suture band passes.

[0006] Preferably, the suture band has a wide band segment and a narrow band segment, the wide band segment being wider than the narrow band segment, and the slit being located on the wide band segment, close to the suture needle.

[0007] Preferably, to ensure suture length and ease of operation, the length of the suture tape is 43-45cm, and the length of the suture needle is 5-7cm.

[0008] Preferably, the length of the broadband segment is 34-36cm and the width is 4-6mm, and the length of the narrow segment is 7-11cm and the width is 2-3mm.

[0009] Preferably, the length of the slit is 2.5 to 5.5 mm to facilitate the passage of the suture band while ensuring the strength of the suture band at both ends of the slit.

[0010] Preferably, the distance between the slit and the end of the suture needle is 1.5 to 2.5 cm.

[0011] Preferably, the material of the suture tape is polypropylene or polyethylene terephthalate.

[0012] Preferably, a smooth connection is formed between the wide band segment, the narrow band segment and the suture needle, and between the wide band segment and the narrow band segment.

[0013] Beneficial effects: Compared with the prior art, this utility model has the following advantages: 1. Facilitates surgical operation: During puncture, the suture needle enters from the front of the uterus. After puncture, one end of the suture band passes through the slit at the other end. The suture band itself rotates around the uterus, and the two ends that need to be knotted are brought to the front of the uterus, making it easy to pull to the front of the uterus for knotting after surgery; 2. Ensures strength: The slit with a specific structure is limited at a specific location, ensuring the strength of the suture band itself and the usable length during ligation; 3. Facilitates intraoperative operation: The straight needle is easy to cooperate with the laparoscope, and there is a smooth transition between the wide and narrow band segments, and between the wide and narrow band segments and the suture needle, which helps to reduce puncture resistance; 4. This ligation band has been used in 100 clinical cases with excellent results. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0016] like Figure 1As shown, this utility model discloses a cervical cerclage band for transabdominal cervical cerclage, mainly composed of a suture band 3 and a suture needle 1. The suture needle 1 is directly connected to both ends of the suture band 3 and is a straight needle, suitable for transabdominal cervical isthmus cerclage surgery. This type of cerclage band eliminates the need to manually straighten bent suture needles, making it more convenient and faster. The suture band 3 is a continuous strip made of non-absorbable synthetic material, such as polypropylene or polyethylene terephthalate (PET), and is flat in shape. One end of the suture band 3 (e.g., the left end) has a slit 2, which allows the remaining end (the right end) of the suture band 3 to pass through. During the procedure, the suture needles 1 at both ends of the suture band 3 are inserted from the front of the uterus on both sides, bringing both ends of the suture band 3 to the back of the uterus. Then, the suture needles 1 are removed, and the right end of the suture band 3 is passed through the slit 2 at its left end. The left end of the suture band 3 is then pulled back in front of the uterus, causing the left end to pull the right end through the puncture suture on the left side of the uterus (this operation allows the suture band 3 to rotate around the uterus). Thus, both free ends of the suture band 3 are transferred to the front of the uterus, facilitating postoperative knotting. In both punctures, the puncture needles 1 enter from the front of the uterus, making the operation convenient and solving the problem of difficulty in puncturing from the back of the uterus. When removing the sutures, they are cut and pulled directly from the front of the uterus, avoiding the difficulty of cutting them from the back and then pulling out the ligation band from the back, thus reducing the risk of uterine rupture due to difficulty in suture removal. Suture needle 1 is made of stainless steel, with a needle length L1 = 5-7cm and a diameter of 1.5±0.1mm.

[0017] Based on width, the suture band 3 is divided into a relatively wide wide segment 31 and a relatively narrow narrow segment 32. The slit 2 is located on the wide segment 31 and close to the suture needle 1 of the wide segment 31, so that the narrow segment 32 can pass through the slit 2, reducing the length of the slit 2 and ensuring the usable length of the suture band 3. At the same time, due to the obvious difference in width between the wide segment 31 and the narrow segment 32, it is also easy to identify the position of the slit 2 during operation.

[0018] The width of the ends of the wide band 31 and narrow band 32 gradually decreases to fit the eye of the suture needle 1 and form a smooth connection with the suture needle 1. A smooth connection is also formed between the wide band 31 and the narrow band 32. The structure gradually changes to facilitate puncture.

[0019] The total length of the suture band 3 is 43–45 cm to ensure sufficient suture length and operability. The wide band 31 is 34–36 cm long and 5 ± 1 mm wide; the narrow band 32 is 7–11 cm long and 2.5 ± 0.5 mm wide. The slit 2 is 4 ± 1.5 mm long, preferably 5 ± 0.5 mm. The distance L2 between the slit 2 and the end of the suture needle 1 is 2 ± 0.5 cm.
