The connecting structure comprises a suture 11 and a group of medical anchors 100 in the embodiment, wherein a third connecting structure and/or a fourth connecting structure are adopted between the suture 11 and the medical anchors 100, the third connecting structure is that the suture 11 simultaneously penetrates into a first threading hole 10, a third threading hole 3 and a threaded hole 5, two ends of the suture 11 are positioned at the top end of a female nail 1 to fix the female nail 1, and the fourth connecting structure is that the suture 11 simultaneously penetrates into a second threading hole 9, a fourth threading hole 6 and a wire passing hole 8, two ends of the suture 11 are positioned at the top end of a sub-nail 2 to install the sub-nail 2 into the female nail 1. As shown in fig. 7B, the suture 11 sequentially passes through the threaded hole 5, the first threading hole 10, the third threading hole 3, the first threading hole 10 and the threaded hole 5 of the female nail 1, that is, two ends of the suture 11 pass through the threaded hole 5, and the female nail 1 with the suture 11 is installed in a preset positioning hole. Similarly, as shown in fig. 7A, the suture 11 sequentially passes through the wire passing hole 8, the second threading hole 9, the fourth threading hole 6, the second threading hole 9 and the wire passing hole 8 of the sub-nail 1, that is, two ends of the suture 11 pass through the wire passing hole 8, and the sub-nail 2 with the suture 11 is installed in the female nail 1. In this embodiment, the suture 11 passes through the inside of the female nail 1 and/or the male nail 2, so that the suture 11 is not contacted with the external thread of the female nail 1 or the male nail 2, the suture 11 is prevented from being cut and damaged, the influence of the thread on the suture 11 is reduced, and the suture can be quickly installed in the positioning hole or the female nail 1, thereby protecting the suture 11 and improving the operation efficiency.
