Adjustable temporary ankle-foot orthosis bracket and method for manufacturing ankle-foot orthosis

Abstract

The invention discloses an adjustable temporary ankle-foot orthopedic bracket, which comprises a first positioning frame, a second positioning frame and a connecting rod assembly connecting the first positioning frame and the second positioning frame. The first positioning frame includes a vertical The support piece, the supporting piece, a pair of calcaneus positioning pieces, a pair of ankle bone positioning pieces, the first adjustment assembly and the second adjustment assembly, and the pair of calcaneus positioning pieces are respectively detachably fixed on the two vertical shafts through the first adjustment assembly. On the supporting part, a pair of ankle bone positioning parts are respectively detachably fixed on the two vertical supporting parts through the second adjustment assembly. A third adjustment assembly fixedly connecting the two. It can flexibly adjust the positions of relevant components, so that the relevant components can be more adapted to the patient's legs and feet, so that the patient's legs and feet can be kept in the best orthopedic state. The invention also discloses a manufacturing method of the ankle-foot orthosis.

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
