Description

Technical Field

[0001] The present invention relates to a bone traction device, and particularly to a leg fracture traction device and method for orthopedics, belonging to the technical field of fracture traction. Background Art

[0002] Fracture traction utilizes the principle of mechanics, and through the pulling effect of gravity on the affected limb, to achieve the purpose of reduction and fixation. Its time and effect depend on the severity, location of the fracture, and treatment purpose. Traction is a common means in fracture treatment. It mainly utilizes the principle of action and reaction in mechanics, and through the pulling of gravity, acts on the affected limb to relieve the tension and retraction of the soft tissues at the fracture and dislocation sites, so that the fracture or dislocation is reduced and the fixation effect is achieved. This is beneficial to relieve muscle spasm, improve venous return, eliminate limb swelling, and create conditions for the manual or surgical treatment of the fracture ends;

[0003] The existing fracture traction techniques mainly rely on the method of applying traction force by means of counterweights, but there are some significant defects. First of all, the counterweights cannot be precisely adjusted, the traction force is limited, and it is difficult to meet the personalized treatment needs of different fracture conditions. Secondly, the counterweights generate shaking during the collision process, resulting in the shaking of the traction frame and steel nails, which is difficult to stabilize the fracture state and is not conducive to the recovery of the fracture. Finally, the existing support systems usually use padded cushions, which are difficult to precisely adjust the support angle, and at the same time, the affected limb is prone to slide on the cushion, which is not conducive to the stability of the traction effect. These technical defects limit the curative effect of fracture traction techniques and the comfort of patients, and there is an urgent need to develop a more precise, stable, and easy-to-adjust fracture traction device;

[0004] To solve the above technical problems, a leg fracture traction device and method for orthopedics are proposed. Summary of the Invention

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] As Figures 1-6 shown, the embodiment of the present invention provides a leg fracture traction device for orthopedics, which is composed of a fixing mechanism 10, a supporting mechanism 20 and a traction mechanism 30.

[0039] The fixing mechanism 10 includes a chassis 11 and a first guide rail 14. Two first guide rails 14 are symmetrically installed on the top of the chassis 11. Two first sliders 13 are slidably connected inside the first guide rail 14. Two first screws 15 penetrate through the inside of the chassis 11.
