Problems solved by technology

This method will increase the weight of the ankle foot orthosis and make it less orthotic due to the unstable connection part
There are also orthoses made by one-time molding, but this kind of orthosis also generally has the following problems: 1. There is no hollowing out on the ankle bone, which makes it inconvenient to move after wearing the ankle-foot orthosis; 2. The arch and sole of the foot Par...

Embodiment 1

[0031] Such as figure 1 , 2 As shown, a 3D printed integrally formed ankle-foot orthosis of this embodiment includes a calf covering fixture 10, an outer support frame 20, an inner support frame 30, and a plantar orthosis 40. The outer support frame 20 The upper end of the outer support frame 20 and the inner support frame 30 are connected to the calf covering fixing member 10, and the lower end is connected to the plantar orthopedic member 40; the outer support frame 20 Separate from the joint of the plantar orthosis 40 to form a lateral malleolus front end fixture 21 and a lateral malleolus back end fixture 22, the lateral malleolus front end fixture 21 and lateral malleolus rear end fixture 22 are provided with lateral malleolus placement holes 23; The plantar orthopedic component 40 also includes an arch orthopedic area 41, a heel protection area 42, and a plantar protection area 43. The inner support frame 30 is connected to the plantar orthopedic element 40 near the arch o...

Embodiment 2

[0033] Such as figure 1 , 2 As shown, the calf covering and fixing member 10 described in this embodiment is a semi-enclosing structure provided with an opening 11, and the height is set at the maximum position of the calf gastrocnemius muscle. The calf covering and fixing member 10 wraps the largest portion of the calf gastrocnemius muscle. Cover, opening 11 facing the shin bone. The calf covering and fixing member 10, the outer support frame 20 and the inner support frame 30 jointly enclose a calf muscle group release area 50, and the calf muscle group is placed in the calf muscle group release area 50 when worn. The opening 11 provided in the calf wrap fixing member 10 can prevent the calf gastrocnemius from being over-wrapped. The calf muscle release area 50 can also avoid friction between the calf muscles and the ankle-foot orthosis, and can also achieve a ventilation effect.

Embodiment 3

[0035] Such as figure 1 , 2 As shown, the arch correction area 41, the heel protection area 42, and the sole protection area 43 described in this embodiment are all closely fitted to the curve of the human foot. The plantar orthosis 40 is also provided with a plurality of ventilation holes 44 penetrating the plantar orthosis 40. The ventilation hole 44 is used for the ventilation of the sole. The arch orthopedic area 41, the heel protection area 42, and the sole protection area 43 closely fit the curve of the human foot to achieve the orthopedic effect and achieve comfort during wearing.

Abstract

The invention relates to an ankle foot orthosis and a manufacturing method of the ankle foot orthosis, in particular to a 3D printing integrally formed ankle foot orthosis and a manufacturing method thereof. The ankle foot orthosis is provided with an outer side ankle placement hole so that friction between the outer side ankle and the ankle foot orthosis can be avoided, and the ankle foot orthosis wears more comfortable; meanwhile, the situation is avoided that due to friction, displacement is generated between the foot and the ankle foot orthosis and thus a correcting effect is influenced. The ankle foot orthosis is provided with a calf muscle group releasing region, when the ankle foot orthosis is worn, the calf muscle group can be placed in the calf muscle group releasing region and prevented from being completely cladded, so that air permeability is achieved, and meanwhile friction between the calf muscle group and the ankle foot orthosis is avoided. By adopting the manufacturingmethod, customized production of the ankle foot orthosis aiming at the ankles and feet in specific shapes can be achieved, and thus the purposes of individual case solving, convenience and comfortableness are achieved.

Description

[0001] 【Technical Field】 [0002] The invention relates to an ankle-foot orthosis and a manufacturing method of an ankle-foot orthosis, in particular to an ankle-foot orthosis integrally formed by 3D printing and a manufacturing method thereof. [0003] 【Background technique】 [0004] Ankle-foot orthosis is a specially customized appliance for foot and ankle deformities. Commonly used for congenital and acquired foot varus, foot drop and various paralytic diseases caused by ankle-foot joint instability, etc., it can expand the contact area between the sole of the foot and the ground, strengthen the support for weight, and the ankle-foot joint It has the functions of stabilizing, improving gait, preventing ankle and foot deformation. [0005] At present, most of the ankle-foot orthoses on the market are produced in multiple parts separately, and then fixed and connected to achieve the installation of the ankle-foot orthosis. This method will increase the weight of the ankle-foot ortho...
