Problems solved by technology

However, the design of traditional orthopedic insoles is not universal, and often cannot correct the abnormal ankle problems of users
In addition, from the perspective of foot biomechanics, a single insole design that completely fits the shape of the sole of the foot often neither corrects foot problems, but also causes new foot pain

preparation example Construction

[0055] A kind of preparation method of flexible orthopedic insole of the present invention, comprises the following steps:

[0056] S1. Judging the position, angle or height that needs to be corrected according to the foot scan image data;

[0057] S101. If the user has symptoms of heel varus, design an inner and outer wedge angle for the heel of the insole; if the heel varus angle is less than or equal to 10°, the inner and outer wedge angle of the insole heel is greater than or equal to 1 / 2 of the user's heel varus angle, and Less than or equal to 10°; if the heel varus angle is greater than 10°, the insole heel inner and outer wedge angle is greater than 10°, and less than or equal to 3 / 2 of the heel varus angle;

[0058] S102. If the user has flat feet, design the arch angle of the insole: according to the user's Pitch angle and Meary angle, increase the longitudinal arch angle on the initial shape of the insole, and the increased angle is equal to the average of the diffe...

Abstract

The invention discloses a flexible orthopedic shoe pad and a preparation method thereof. The method comprises the following steps: establishing a shoe pad model having foot bottom morphology accordingto foot data; by acquiring foot evaluation index data, foot bottom pressure distribution data and foot appearance scanning data, by using a corresponding optimization relation between key shoe-pad appearance parameters and the foot evaluation indexes and a corresponding relation between material performance distribution of the shoe pad and foot bottom pressure distribution, adjusting the outer contour model of the orthopedic shoe pad and the mechanical property of the material; and preparing the flexible orthopedic shoe pad by adopting a 3D printing process. The shoe pad is filled by virtue of a porous structure with adjustable mechanical property of the material, and finally the personalized porous shoe pad model is printed, so that the shoe pad can bring the optimal comfort level to a wearer and is convenient and rapid.

Description

technical field [0001] The invention belongs to the technical field of orthopedics, and in particular relates to a flexible orthopedic insole and a preparation method thereof. Background technique [0002] The foot is an important weight-bearing organ and exercise organ of the human body, which bears the weight of the body and the reaction force of the ground. Weight will put pressure on the feet. If there is a problem with the foot itself or a wrong gait, the pressure will be improperly absorbed by the joints. Once there is a problem with the body's strength line, it will gradually accumulate into other diseases, which will affect the ankle, knee, The pelvis, lumbar spine and other parts are affected. Flat feet, high arched feet, hallux valgus, Achilles tendonitis, metatarsalgia, and foot and ankle diseases such as congenital or acquired long and short legs, etc., will cause ankle joint deformation, and then compensatory cause knee and hip pain. The problem. [0003] Ort...
