Adjustable temporary ankle-foot orthopedic support and manufacturing method of ankle-foot orthopedic device

Abstract

The invention discloses an adjustable temporary ankle-foot orthopedic support, which comprises a first positioning frame, a second positioning frame and a connecting rod assembly for connecting the first positioning frame and the second positioning frame together. The first positioning frame comprises vertical supporting pieces, a bearing piece, a pair of calcaneus positioning pieces, a pair of ankle bone positioning pieces, a first adjusting assembly and a second adjusting assembly. The pair of calcaneus positioning pieces is detachably fixed to the two vertical supporting pieces through first adjusting assembly respectively. The pair of ankle bone positioning pieces is detachably fixed to the two vertical supporting pieces through the second adjusting assembly respectively. The second positioning frame comprises a front sole bottom supporting piece, a front sole top positioning piece and a third adjusting assembly used for detachably and fixedly connecting the front sole bottom supporting piece and the front sole top positioning piece. The positions of related components can be flexibly adjusted, so that the related components can be more adaptive to legs and feet of a patient, and the legs and the feet of the patient can be kept in the optimal orthopedic state. The invention further discloses a manufacturing method of the ankle-foot orthopedic device.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to an adjustable temporary ankle-foot orthosis bracket and a manufacturing method of an ankle-foot orthosis. Background technique [0002] As the movement joint of the human body, the ankle joint is also the joint closest to the ground and bears the most weight. Especially when running and jumping, the ankle joint bears huge loads and impacts. Therefore, ankle sprains are also relatively common in daily life. common. After ankle joint injury, if timely and correct treatment is not carried out, symptoms such as decreased lateral support strength of the ankle joint, decreased proprioception of the joint, and excessive laxity of ligaments will appear, which may easily cause repeated ankle sprains and sequelae such as ankle joint dysfunction. [0003] In order to treat ankle joint injuries, improve ankle motor function and gait reconstruction, injured patients need a lot of r...

Problems solved by technology

In practice, ankle-foot-orthosis is a common ankle-joint treatment device. Traditional ankle-foot-orthosis has many shortcomings, such as complicated production process, long production time, and some orthoses cannot be completely suitable for patients, etc.

[0004] Based on the shortcomings of the traditional manufacturing process, there is a method of using 3D printing to make ankle-foot orthoses on the market. The production cycle can be greatly shortened by 3D printing technology. However, the existing methods of making orthotics based on 3D printing are generally The data of the patient's calf is obtained by scanning the patient's calf in 3D, and then the orthosis is modeled in 3D by using auxiliary software based on the data, and finally the 3D model is printed out by 3D printing technology to produce an ankle-foot orthosis. In practice, since this method is an ankle-foot-orthosis produced by statically scanning the patient's calf in three-dimensional way, this ankle-foot-orthosis is often difficult to fit the patient's calf, and the correction effect is poor
