Problems solved by technology

[0002] We know that under the guidance of AO theory, the current surgical orthopedic bone plates used to treat fractures are mostly strong compression internal fixation, the fracture healing quality is poor, and there are many complications, because (1) the current bone plates are used in the treatment of fractures or During orthopedic treatment, strong pressure internal fixation is used, which is closely attached to the surface of the bone, resulting in the compression and necrosis of the periosteum supplying the blood supply of ...

Embodiment Construction

[0011] specific implementation

[0012] The non-contact bone-end arc-shaped stress bone plate is fixed on different parts of the bone-end fracture, and the stress is transferred to the fracture end through the force-deformation movement of the fixed-section arc-shaped structure; the non-contact bone-end arc-shaped stress bone plate structure is It is fixed on the fracture site by a new type of bone screw, so as to achieve non-contact fixation.

[0013] exist figure 1 , figure 2 In the shown embodiment, the non-contact bone-end arc-shaped stress bone plate is fixed on the fracture site by a new type of bone screw, as shown in image 3 , 4 As shown, there is a distance of 0.3mm to 0.5mm between the bone plate and the bone. Through non-contact fixation, the periosteum is neither stripped nor compressed and necrotic, so that the fracture end has good blood supply and promotes fracture healing. Stress is transferred to the fracture end through the arc-shaped structure of the f...

Abstract

The invention provides a non-contact capitulum curved stress bone fracture plate. The plate is fixed on a catagmatic part through novel bone screws with 0.3 to 0.5 mm of distance between the bone fracture plate and the bone; the non-contact fixing mode is adopted, so the periosteum cannot be peeled off and also cannot become necrosis caused by pressing, thereby ensuring that the catagmatic part has good blood supply, and promoting the healing of the catagmatic part. The stress deformation movement of the fixing section curved structure transfers the stress to the catagmatic end, so that the bone after fracture fixation can also be stimulated by appropriate stress to accelerate healing and reduce complication. The plate has the advantages of shortening the healing time and achieving biological fixation.

Description

technical field [0001] The invention belongs to the field of orthopedic orthopedics in clinical medicine, and is used for fixing fractures and orthopedics and promoting fracture healing. Background technique [0002] We know that under the guidance of AO theory, the current surgical orthopedic bone plates used to treat fractures are mostly strong compression internal fixation, the fracture healing quality is poor, and there are many complications, because (1) the current bone plates are used in the treatment of fractures or During orthopedic treatment, strong pressure internal fixation is used, which is closely attached to the surface of the bone, resulting in the compression and necrosis of the periosteum supplying the blood supply of the fracture end, and further destroying the blood supply of the fracture end damaged by the fracture, resulting in the above complications and prolong the healing time and even lead to nonunion; (2) The stress shielding caused by strong inter...
