However, using traditional methods such as trial models to obtain patient foot data only considers the surface topography characteristics of the patient's sole, and does not consider the foot skeletal system, muscle ligament system, and plantar stress under different stances that affect the distribution of plantar stress. Changes, personalized design is not enough
Secondly, the traditional desi

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] This embodiment carries out the whole process from the collection of patient data to the output of the diabetic foot insole model, which is only used to illustrate and explain the present invention, and is not intended to limit the present invention.

[0035] refer to figure 1 , a personalized design method for diabetic foot insoles, comprising the following steps:

[0036] Step 1: Collect a large number of CT and MRI data of the patient's foot, and use Mimics (Version 16.0, Materialize, Belgium) to construct a parametric model of the patient's internal bones, ligaments, muscles, etc., to form a set of geometric features of the foot bones, bone- Muscle assembly features, ligament-skeleton assembly features, and cartilage features are a patient foot parametric model library, and a general foot bone model is established;

Abstract

An individualized design method for a diabetic foot shoe pad comprises the steps that firstly, a general foot bone model is established, then key size data of the diseased foot is acquired, the general foot bone model is scaled to obtain an individualized bone model of the diseased foot, then three-dimensional data of surface appearance of the diseased foot is acquired and is coupled with the individualized bone model, and assembly is performed in CAN software to obtain an individualized three-dimensional model of the diseased foot; then, based on the three-dimensional model of the foot, a diabetic foot shoe pad base model completely fit with the foot is established according to foot bottom appearance characteristics and is imported into finite element analysis software with the three-dimensional model of the foot to perform assembly and grid partitioning, a finite element model of a foot-shoe pad is obtained, then a stress distribution result is analyzed and calculated, the modulus and structures of zones of the diabetic foot shoe pad base model are modified to form a final diabetic foot shoe pad model. The designed shoe pad meets the individualized demand, meanwhile a product design period is shortened, and the cost is reduced.

Description

technical field [0001] The invention belongs to an insole design method, in particular to a personalized design method for diabetic foot insoles. Background technique [0002] Diabetic foot is a common complication of diabetes. The important cause of its formation is the uneven pressure on the patient's foot in daily life, which leads to ulceration at the site of concentrated stress, which deteriorates and eventually leads to amputation. Therefore, a suitable diabetic foot insole design can effectively improve the supporting capacity of the arch and improve the stress distribution of the patient's sole, thus playing a certain role in the prevention and adjuvant treatment of diabetic feet caused by uneven stress distribution. However, using traditional methods such as trial models to obtain patient foot data only considers the surface topography characteristics of the patient's sole, and does not consider the foot skeletal system, muscle ligament system, and plantar stress un...
