Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic instruments, and in particular to a device for promoting fracture healing. Background Art

[0002] After a fracture, the patient's affected limb becomes deformed, swollen, painful, and has impaired mobility. The patient dares not and is unwilling to move the affected limb, which greatly reduces the effect of the muscle pump and slows blood flow. In addition, the blood is in a hypercoagulable state after the injury, so the patient is very prone to thrombosis. If thrombosis occurs, appropriate immobilization is required, which further aggravates this vicious cycle.

[0003] In order to promote fracture healing in patients with fractures, the existing technology uses intermittent pneumatic pressurization devices for clinical treatment. The intermittent gas pressurization can promote blood circulation at the fracture site, avoid blood coagulation at the fracture site, the formation of thrombus, resulting in blood stagnation and slow fracture healing.

[0004] At present, several clinically proven solutions that can promote fracture healing are as follows:

[0005] Intermittent pneumatic compression: This technology uses an inflatable device to apply intermittent pressure to stimulate blood circulation and metabolism at the fracture site and promote the healing process. Through periodic pressure changes, it can increase local oxygen supply and promote the proliferation and differentiation of bone cells.

[0006] Pulsed magnetic field: Pulsed magnetic field therapy promotes the regeneration of bone tissue by applying a magnetic field of a specific frequency and intensity. Studies have shown that pulsed magnetic fields can enhance the activity of bone cells, promote bone mineralization and angiogenesis, and thus accelerate fracture healing.

[0007] Low-intensity pulsed ultrasound: Low-intensity pulsed ultrasound (LIPUS) is a non-invasive technology that uses sound waves to stimulate the fracture site and promote bone healing. Its mechanisms include increasing the metabolic activity of bone cells, increasing the generation of osteoblasts, and promoting collagen synthesis.

[0008] Transcutaneous electrical stimulation: Transcutaneous electrical stimulation is a method of applying electric current through the surface of the skin to stimulate cell activity at the fracture site. Studies have shown that electrical stimulation can promote the proliferation and differentiation of osteoblasts and enhance the healing ability of bone tissue.

[0009] These techniques are only used individually in clinical treatment. If they can be used in combination, they can complement each other and improve the efficiency and effectiveness of fracture healing. Summary of the invention
