Problems solved by technology
However, in this conventional treatment method, after the fracture block is fixed by hollow screws, it is necessary to find additional points of attachment of the ligament or tendon and implant anchors, and finally the ligament or tendon can be fixed by sutures, which greatly shortens the operation time. growth, the surgical trauma is relatively large, and too much implantation will also cause a great psychological burden on the patient

Embodiment Construction
[0026] The following is attached Figure 1-2 The application is described in further detail.
[0027] The embodiment of the present application discloses a hollow screw structure that can connect tendon and ligament. refer to figure 1 The hollow screw structure capable of connecting tendon and ligament includes a hollow screw body 1 and sutures 2 detachably connected to the hollow screw body 1 .
[0028] refer to figure 1 with figure 2 The hollow screw body 1 includes a screw head 11 and a screw rod 12 affixed to one end of the screw head 11. On the outer wall of the screw rod 12, there is a thread hole 123 connected to the inside of the hollow screw body 1 for the suture 2 to pass through. 2 is passed through the thread hole 123 to realize the detachable connection between the suture 2 and the hollow screw body 1. When in use, one end of the suture 2 is first inserted into the hollow screw body 1 from one thread hole 123, and then passed through the other end of the thr...

The invention relates to a hollow screw structure connectable to tendon ligaments, and pertains to the field of medical instruments. The hollow screw structure connectable to the tendon ligaments comprises a hollow screw body, and a suture detachably connected to the hollow screw body; the hollow screw body consists of a screw head, and a screw rod fixedly connected to one end of the screw head; and a suture hole is formed in the outer wall of the screw rod, and communicated with the interior of the hollow screw body so as to allow the suture to penetrate through. The hollow screw structure connectable to the tendon ligaments has the effects of being capable of shortening operation time, minimizing surgical trauma, and reducing psychological burden on a patient caused by excessive implantation.
Description
technical field [0001] The present application relates to the field of medical devices, in particular to a hollow screw structure that can connect tendons and ligaments. Background technique [0002] Fracture refers to the complete or partial rupture of the continuity of the bone structure, which will cause damage to the ligaments or tendons around the fracture. The current conventional surgical treatment method is: after the fracture fragment is reset, the fracture fragment is fixed with hollow screw or Kirschner wire, and the attached ligament or tendon on the fracture fragment is also stable along with the fixation of the fracture fragment. If the ligaments or tendons around the fracture fragments are extensively damaged, and the mechanical stability cannot be achieved by simply fixing the fracture fragments, the ligaments or tendons will be fixed with wire anchors. Specifically, the suture fixation point, that is, the attachment point of the ligament or tendon, is first...
