Description

Technical Field

[0001] This utility model relates to the field of suture needle technology, specifically a double-lead loop suture needle. Background Technology

[0002] With the continuous development of sports medicine technology, tendon reconstruction surgery has become increasingly widely used in clinical applications. The procedure for tendon reconstruction surgery typically includes steps such as extracting the levator tendon, weaving the tendon, preparing the tendon tunnel, and fixing the tendon. During the surgery, the levator tendon is first woven using a tendon preparation platform, suture needles, and sutures; then, the prepared tendon is guided through the tunnel to the desired location and fixed using tools such as screws or titanium plates to achieve the repair goal of tendon reconstruction.

[0003] However, existing suturing techniques have many problems, especially in tendon weaving. Traditional suture needles typically have holes in the needle body, which makes the sutures prone to blockage and jamming during operation, increasing the complexity of the surgery and potentially causing inconvenience. More seriously, traditional tendon weaving methods often use double suture needles for left-right crossing operations. This method is not only cumbersome but also requires penetrating the tendon through multiple needle holes, increasing the wound area and potentially causing greater damage to the tendon. At the same time, such operations require a high level of surgical skill, often relying on the surgeon's experience to minimize trauma, increasing the unpredictability of the surgery, raising the surgical risk, and prolonging the operation time.

[0004] To address the aforementioned issues, existing technologies have proposed double-guide loop suture needles, which simplify operations and improve surgical efficiency through a "one needle, two sutures" approach. The double-guide loop suture needle, with two guide loops on the needle body, facilitates suture guidance and reduces the number of wounds during tendon weaving, thereby minimizing tendon damage. However, in practical applications, existing double-guide loop designs have certain limitations. Specifically, while the two guide loops are typically fixed within the same loop fixing hole, during installation, the installation ends of these two guide loops are prone to interference, causing tangling and crossing, resulting in inconsistent loop orientations. This increases the difficulty of operation for medical staff and affects the smooth progress of the surgery. Utility Model Content

[0005] To address the technical problems existing in current tendon suturing techniques, this invention provides an improved double-lead loop suture needle, which can effectively avoid the problem of mutual interference between the two lead loops.

[0006] A double-lead loop suture needle, comprising:

[0007] The suture needle has a mounting hole at the end away from the needle tip;

[0008] The first lead ring is fixed at both ends in the mounting holes;

[0009] The second lead ring has its two ends fixed in the mounting holes, and the size of the second lead ring is smaller than that of the first lead ring;

[0010] An isolation structure is provided inside the mounting hole to prevent the ends of the first lead ring and the second lead ring inside the mounting hole from crossing and entangled with each other.

[0011] Furthermore, the isolation structure includes a partition that divides the mounting hole into two independent spaces, with the two ends of the first lead ring and the second lead ring respectively fixed in their respective independent spaces.

[0012] Furthermore, the isolation structure consists of two sets of ring-shaped components that fix the two ends of the same lead ring together; the ring-shaped components are straps, fixing hoops, or cable organizers with two independent lead ring end holes.

[0013] Furthermore, the isolation structure is a crimped tube with four independent lead ring end through holes; one section of the crimped tube is provided with a mounting part, which is inserted into the mounting hole.

[0014] This invention effectively prevents mutual interference between the ends of the two lead rings by setting an isolation structure in the mounting hole at the end of the suture needle and providing a variety of feasible structures. This avoids the mounting ends of the two lead rings from getting tangled together and the lead rings from having inconsistent orientations, thus making it convenient for medical staff to operate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] A double-lead loop suture needle, such as Figure 1 As shown, it includes a suture needle 1 and a first lead loop 2 and a second lead loop 3 disposed at its end. The end of the suture needle 1 away from the needle tip has a mounting hole 11, and the two ends of the first lead loop 2 and the second lead loop 3 are fixedly fixed in the mounting hole 11.

[0024] Both the first lead ring 2 and the second lead ring 3 are made of NiTi shape memory alloy. The second lead ring 3 is a short lead ring, and the first lead ring 2 is a long lead ring.

[0025] The mounting hole 11 is provided with an isolation structure to prevent the two ends of the first lead ring 2 and the second lead ring 3 from interfering with each other.

[0026] In this embodiment, the isolation structure includes a partition 5, which divides the mounting hole 11 into two independent spaces. The two ends of the first lead ring 2 and the second lead ring 3 are respectively fixed in their respective independent spaces, such as... Figure 2 As shown. Figure 2 The two circular holes 21 and 22 shown on the left represent the two ends of the first lead ring 2, and the two circular holes 31 and 32 shown on the right represent the two ends of the second lead ring 3. Under the action of the partition 5, the first and second lead rings are separated. (See attached image.) Figure 3 This effectively prevents mutual interference between the two lead ring ends.

[0027] For fixing both ends of the same lead ring, methods such as straps or fixing clamps can be used (forming a closed loop after fixing). This embodiment is preferred. Figure 4 The ring-shaped kit shown provides limiting and fixing to both ends of the same lead ring, which is superior to fixing methods such as straps and clamps. Figure 4 The ring-shaped kit shown, combined with the U-shaped structure of the lead ring, makes fixing easier and faster.

[0028] also, Figure 4 The ring-shaped kit shown also serves as an isolation mechanism. When used independently of the partition 5, it can effectively isolate the ends of the two lead rings.

[0029] The ring-shaped kit can also be a customized cable management device, see [reference]. Figure 2 The spaces on both sides of partition 5 can be considered as independent cable management units. Figure 2The two round holes 21 and 22 shown on the left are for the two ends of the first lead ring 2 to pass through, and the two round holes 31 and 32 shown on the right are for the two ends of the second lead ring 3 to pass through.

[0030] The operating steps of the double-lead loop suture needle disclosed in this utility model in tendon braiding surgery are as follows:

[0031] 1) Tighten the tendon to be braided and fix both ends to the tendon management platform;

[0032] 2) Secure the middle of the suture to the base of the tendon near one end;

[0033] 3) Wrap the two ends of the suture around the tendon from both sides to above the tendon;

[0034] 4) Insert one end of the suture into the short guide loop and the other end into the long guide loop. Insert the double guide loop suture needle with the suture threaded through it from top to bottom at the predetermined distance from the previous needle hole. After both ends of the double guide loop suture needle and the suture thread have passed through the tendon, separate the double guide loop suture needle from the suture thread and pull the suture thread downwards to tighten it.

[0035] 5) Repeat steps 3) and 4) using a cross-weaving method to weave the tendon until the other end of the tendon, then tie the suture tightly against the tendon and cut the tail thread.

[0036] Example 2

[0037] In this embodiment, the isolation structure is a crimping tube 4, which has four independent lead-loop end through holes 41. The crimping tube 4 can also be understood as the cable organizer in Embodiment 1, but in this embodiment it is an integral structure.

[0038] To facilitate fixation, a section of the crimping tube 4 is provided with an mounting part 42, which is inserted into the mounting hole 11. During assembly, by squeezing the tail end of the suture needle 1, the mounting part 42 is embedded into the mounting hole 11, thereby fixing the crimping tube 4. At the same time, the crimping process deforms the through hole 41 to fix the two ends of the first lead ring 2 and the second lead ring 3, thereby avoiding the mounting ends of the two lead rings from tangling and the lead rings from having inconsistent orientations, making it convenient for medical staff to operate.

[0039] To meet the requirements of its extrusion assembly, the compression fitting can be made of silicone, preferably medical-grade silicone that is certified by the FDA (U.S. Food and Drug Administration) or ISO 10993. It is non-toxic, odorless, does not release harmful substances, and can come into contact with human tissues or body fluids.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
