Embodiment 1

[0101] refer to figure 1 and figure 2, the first aspect of the present application discloses a bone screw, comprising a hollow body 100, the interior of the hollow body 100 has a first chamber 110 and a second chamber 120 that communicate with each other; wherein, the material of the hollow body 100 is a polymer The material, which may preferably be polyetheretherketone or absorbable material, does not cause harm to the human body, while significantly improving the visualization of bone and joint spaces. The hollow body 100 provides a significant clinical advantage over traditional metal implants in that the surgeon can better assess postoperative healing by "seeing through" the implant and looking down at the bony structure on an x-ray. The use of polyetheretherketone or absorbable materials, with good plasticity and radiolucency, does not require dismantling during clinical examination and diagnosis, and significantly improves the visualization of bone and joint spaces.

Embodiment 2

[0113] refer to Figure 4 , the core rod 200 provided inside the hollow main body 100 in this embodiment is arranged in the same structure as the core rod 200 provided in the first embodiment, so only the hollow main body 100 in this embodiment will be described in detail.

[0114] The outer wall of the hollow body 100 is provided with a first thread segment 131 and a second thread segment 132 . The length of the first thread segment 131 is greater than the length of the second thread segment 132 , and the pitch of the first thread segment 131 is greater than that of the second thread segment 132 . The thread pitch; the caudal plane of the hollow body 100 is provided with a thread loop 140 for threading the suture, this embodiment can achieve precise guidance of the bone; It is stable and can form a gap with the surrounding bone, which is beneficial to the small movement of bone healing and improves the effect of fracture healing; the setting of the thread ring 140 forms a thr...

Embodiment 3

[0118] refer to Figure 5 , On the basis of the second embodiment, the difference from the second embodiment is that there are two wire loops 140, and the two wire loops 140 are arranged symmetrically; it should be noted that the number of wire loops 140 can also be flexibly set according to requirements, to meet suture needs.

Abstract

The invention discloses a bone screw and a knotting-free bone setting system, and aims to solve the problems that during bone setting, the guiding precision is poor, soft tissue injury is often caused at a fracture position, and an existing bone screw cannot be fixed and repaired. The bone screw comprises a hollow main body and a core rod arranged in the hollow main body, the hollow main body comprises a first chamber and a second chamber which are communicated with each other; the core rod comprises a first acting section matched with the first cavity and a second acting section matched with the second cavity; by arranging the hollow main body, implantation can be carried out along the positioning needle, an injured part is accurately fixed, the guiding precision is high, and injuries to a fracture area are effectively reduced; pressure can be provided for different areas of the bone, so that the multiple areas are easy to heal; the hollow body has good plasticity and ray semi-transmissivity, does not need to be dismantled during clinical examination and diagnosis, and obviously improves visualization of bone and joint space.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a bone screw and a knot-free bone system. Background technique [0002] In the medical trauma orthopaedics department, patients with fractures, fractures with cartilage avulsion, and fractures with soft tissue tears are common. The existing treatment is open surgery or surgery with the help of X-ray instruments. The common techniques for treating bone injuries are: Bone screw (made of titanium alloy), bone plate (made of titanium alloy). Common techniques for the treatment of soft tissue injuries are wire anchors and interface screws. [0003] The current problems mainly include the following: open surgery causes greater trauma to the lesion, increases the chance of infection and inflammation, prolongs the recovery period in the later period, and the scars left on the body surface after recovery are not easy to remove, which affects the appearance. Bone screws...
