Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a vascular suture used for repairing vascular wall damage. Background Art

[0002] Vascular wall injury is a relatively rare complication during surgery, often occurring during lymph node dissection, vascular separation, exposure, and denudation. Because vascular injury is relatively rare, many surgeons lack experience in its management. This is especially true when heavy bleeding is observed, which can be extremely stressful. If untimely or inappropriately addressed, it can lead to vascular wall tears, excessive blood loss, other collateral damage, and conversion from laparoscopy to open surgery, seriously endangering the patient's physical and mental health.

[0003] Promptly suturing ruptured blood vessels and restoring a clear surgical field is crucial. However, current vascular sutures do not immediately stop bleeding after the first stitch. If bleeding continues and the field of vision becomes obscured, the second stitch can significantly prolong the time required, potentially leading to incomplete suturing and vessel rupture, further stressing the surgeon. Careless handling can also cause the suture to pull off, wasting the previous stitch and delaying the optimal timing for vascular repair.

[0004] In order to further tighten the vascular suture, the Chinese patent application number CN202020961210.8 discloses a vascular suture for laparoscopy, which is achieved by forming a ring at the end of the suture with a first tail line. However, its use is relatively cumbersome. At the beginning of use, the suture needle needs to be passed through the ring to form a thread hole. When performing the first stitch of vascular suture, the suture needle needs to be passed through the suture tissue and then through the thread hole before it can be tightened. This is difficult to operate in the case of heavy bleeding, emergency situation, and psychological tension of the surgeon, and will delay the operation time.

[0005] Therefore, a new vascular suture that can reduce the difficulty of suturing is designed. Utility Model Content

[0006] The utility model aims to provide a vascular suture for repairing vascular wall damage, which can reduce the difficulty of suturing when the vascular wall is damaged.

[0007] The purpose of this utility model is achieved through the following technical solutions:

[0008] A vascular suture for repairing vascular wall damage is characterized by comprising a suture needle, a suture, an anchoring sheet and a tail wire, wherein one end of the suture is connected to the suture needle and the other end is connected to the anchoring sheet, and one end of the tail wire is connected to the anchoring sheet.

[0009] The utility model is further configured as follows: the anchoring piece is a circular piece with a radius of 0.2-0.4 cm, or a square piece with a side length of 0.4-0.7 cm, or a rectangular piece with a length of 0.4-0.7 cm and a width of 0.2-0.4 cm.

[0010] The utility model is further configured as follows: the arc of the suture needle is 125-155 degrees, and the length is 6.5-15 mm.

[0011] The utility model is further configured as follows: the suture thread is a blue single-strand polypropylene thread with a length of 15-20 cm.

[0012] The utility model is further configured as follows: the tail wire is located behind the anchoring piece.

[0013] The utility model is further configured as follows: the tail wire is a blue single-strand polypropylene wire with a length of 4-5 cm.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] After the first stitch of the vascular suture is completed, the suture is pulled, and the anchoring sheet is pressed against the vessel wall, thereby tightening the vessel rupture and partially covering the rupture to reduce bleeding and maintain a clear field of vision. After tightening, the tension is maintained, which facilitates the smooth implementation of subsequent sutures. When a knot is required, the tail wire is pulled to simultaneously tighten the sutures on both sides, closing the vessel rupture, and smoothly tying the knot to complete the repair of the vessel wall. The vascular suture of the utility model simplifies the suturing operation, reduces the difficulty of suturing, can better reduce bleeding during surgery, prevent suture slippage, and achieve the purpose of faster suturing, hemostasis, and repair of damaged blood vessels.

[0022] The present invention is further described below in conjunction with the embodiments.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] Example:

[0025] like Figure 1 The vascular suture for repairing vascular wall damage according to this embodiment is shown, which includes a suture needle 1, a suture 2, an anchoring sheet 3 and a tail wire 4.

[0026] The suture needle 1 of this embodiment has an arc of 125-155° and a length of 6.5-15 mm. The tail end of the suture needle 1 is connected to one end of the suture 2, the other end of the suture 2 is connected to the anchor plate 3, and one end of the tail wire 4 is connected to the anchor plate 3, and the tail wire 4 is located behind the anchor plate 3.

[0027] The anchor sheet 3 is made of polypropylene and is a circular sheet with a radius of 0.2-0.4 cm. In other embodiments, the anchor sheet 3 can also be a square sheet with a side length of 0.4-0.7 cm, or a rectangular sheet with a length of 0.4-0.7 cm and a width of 0.2-0.4 cm. The edges of the anchor sheet 3 are rounded.

[0028] The suture 2 of the present embodiment is a blue single-strand polypropylene thread with a length of 15-20 cm. The tail thread 4 is a blue single-strand polypropylene thread with a length of about 4-5 cm.

[0029] The process of suturing the blood vessel 5 using the vascular suture of this embodiment is as follows:

[0030] When in use, the suture needle 1 is passed through the blood vessel wall at the position of the blood vessel rupture 6 to suture. After the first needle passes through the blood vessel wall, the suture 2 is pulled to make the anchor sheet 3 lean against the blood vessel wall, and the suture 2 can be tightened. Figure 2 The schematic diagram after the first stitch is shown. Tightening can reduce bleeding and facilitate the second stitch while maintaining tension. Figure 3 The diagram shown is after the second stitch is sutured. Figure 4 As shown, after the "figure eight suture" is finally completed, the tail wire 4 is pulled and the sutures 2 on both sides are tightened at the same time to achieve hemostasis, and the blood vessel wall is repaired and sutured after knotting.
