Embodiment 1

[0033] The 3D scanning and design environment versions involved in this embodiment are GeomagicStudio2013, Solidworks2013 and Geomagicspark2013.

[0034] Such as figure 1 As shown, this embodiment includes: a thigh support part 1 , a connecting part 3 and a calf support part 2 connected in sequence.

[0035] The thigh support part 1 is a circular curved surface with a flat top and a concave bottom.

[0036] The calf support part 2 is an annular curved surface with a notch in the middle.

[0037] The connecting part 3 includes: an inner leg connecting unit and an outer leg connecting unit, wherein the inner and outer connecting units are respectively located on the left and right (inner and outer) sides of the knee joint, and are respectively connected with the support parts of the thigh and the calf up and down.

[0038] Such as figure 2 As shown, the described leg inner connecting unit includes: leg inner upper connecting piece 4, leg inner lower connecting piece 5 and gu...

Abstract

The invention discloses a load-balanced knee joint orthopedic brace and a 3D printing method thereof. The printing method includes designing and printing of a thigh supporting part, a shank supporting part and a connecting part; both the thigh supporting part and the shank supporting part are represented as an annular curved surface; the connecting part comprises a leg inner side connecting unit and a leg outer side connecting unit; and the designing includes 3D scanning and modeling, manifold, relaxation, offsetting and shelling. The brace disclosed by the invention is simple in structure and reasonable in design, and is capable of preventing further abrasion of a knee joint under a flexion-extension state; and the printing method, which conducts 3D printing by virtue of polylactic acid fiber, has a good physical effect.

Description

technical field [0001] The present invention relates to a technology in the field of medical rehabilitation equipment, in particular to a load-balanced knee joint orthopedic brace and its implementation method. Background technique [0002] The knee joint is the most complex joint in the whole body. It is the first joint in terms of load bearing and exercise capacity, and also plays a pivotal role in the activities of the lower limbs. Therefore, the injury rate of the knee joint is higher than that of other joints in the whole body. Among the many injuries of the knee joint, osteoarthritis is one of the most common diseases. Long-term, large joint loads and deformities of the lower limbs are the main external causes of osteoarthritis. The load-balanced orthopedic brace, by correcting the deformed force line of the lower limbs, reducing the load on the affected joints and reducing the friction of the articular surfaces, has become one of the important means to relieve the pai...
