When the suture needle component with the suture provided by the embodiment of the utility model is adopted for suturing, the annular suture 101 which is the farthest away from the suture needle can be firstly utilized for the first suturing, and after the suture needle operation is finished, the annular suture 101 is cut off and knotted, so that the first suturing operation can be finished; next, the last sewing operation is repeated for each of the annular sewing threads 101 in turn in a direction close to the sewing needle (specifically, in a direction from right to left in fig. 1), so that if the sewing thread 10 has n annular sewing threads, n sewing operations can be performed, which is shorter than the time interval between two consecutive sewing operations, and is close to continuous without interval, compared with the case where the sewing thread needs to be replaced after one sewing operation or the case where the sewing assembly of the related art needs to be replaced, so that the requirement of rapid sewing at present can be satisfied.

Preferably, n is 2, so that the suture line is prevented from being too long and having a certain influence on the suture speed.

In addition, each suture unit in the embodiment is an annular suture coil, namely each suture line is a double line, so that the Knot can be knotted by adopting a Nice knotting method, and the knotting is reliable; and the double-line strength is high, and the tissue with large tension can be fixed, so that a stable environment can be created for the sutured tissue, the high-strength tissue can be well repaired, and the device is suitable for the suture fixation of fracture blocks, the suture of tendons and ligaments for joint replacement, the tissue repair of sports injury and the like.

Furthermore, if adopt the utility model provides a suture needle subassembly of stylolite is disposable product, this and the suture needle subassembly compares for disposable product among the prior art, can improve the utilization ratio of sewing needle to reduce cost.

The specific manner in which two adjacent looped suture lines 101 are connected according to the embodiment of the present invention will be described in detail below with reference to fig. 1 to 4.

In the first way, referring to fig. 1, every two adjacent ring-shaped sutures 101 are connected through the ring-hole ring in a buckling manner, that is, a single line of each ring-shaped suture 101 passes through the ring-hole of the ring-shaped suture 101 adjacent to the single line.

In a third way, referring to fig. 3, every two adjacent circular sutures 101 are connected end to end while being straightened in a direction away from the needle.

In a fourth way, referring to fig. 4, every two adjacent circular stitching lines 101 are connected by a connecting line 103.

In the fourth mode, it is preferable that the diameter D1 (equal to D1+ D2) of the circular suture 101 in the case of being straightened in the direction away from the suturing needle be equal to the diameter D2 of the connecting thread to which the circular suture is connected, so that the diameter of the entire suture can be made uniform, i.e., the thickness can be made the same, whereby damage to the sutured tissue and blood leakage during the suturing operation can be reduced. Further preferably, d1 ═ d2 ensures the reliability of the annular suture 101. Specifically, D1 ═ D2 ═ 1.5mm, and D2 ═ 3 mm.

In this embodiment, as shown in FIGS. 1-4, the suture is provided with a stop 102 at the tail of the suture when it is straightened in a direction away from the needle (from right to left); the stopper 102 is used to completely pull out the entire suture from the suture tissue, so that the entire suture is prevented from being pulled out when the pulling force applied to the suture needle by the medical staff is large, and thus, the occurrence of malfunction can be prevented.

Specifically, the blocking portion 102 is formed by knotting, which is convenient and feasible. More specifically, the closed loop suture farthest from the suture needle is formed by knotting both ends of a loop suture having one opening, and the knot formed by the knotting may serve as the stopper 102.

Preferably, the length of each of the looped suture threads is equal in the case where the suture threads are straightened in a direction away from the suture needle. Of course, the length L can be specifically set according to actual requirements to meet the requirement of one-time stitching under different situations.
