Problems solved by technology

However, CNC machine tool processing is a material reduction process. Compared with the additive manufacturing of 3D direct printing, the material is wasted.
In addition, although materials with different textures are available, only one material can be selected for a specific insole (two kinds of texture materials cannot be used to make an insole at the same time), and the density and elasticity of the insole cannot be changed through design as needed. , so the effect of dispersing the patient's plantar pressure is limited

Embodiment Construction

[0051] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0052] A preparation method for 3D printing diabetic foot insoles, comprising the following steps:

[0053] 1) Patient condition check:

[0054] 1.1) Inquire and record the patient's physical condition, including blood sugar status, diabetic complications (retinal, renal function, etc.), chronic diseases (stroke, fracture, etc.), nutritional status;

[0055] 1.2) Check the condition of the patient's foot, the specific method is as follows:

[0056] 1.2.1) Foot structure:

[0057] a) Foot structure measurement: According to the Najjarine Assessment System (Najjarine Assessment System), the tibial torsion angle of the bilateral lower limbs, the length of the bilateral lower limbs, the standing calcaneal rest position (RCSP), the standing calcaneal neutral position (NCSP), the internal and external sides of the forefoot were measured. Th...

Abstract

The invention discloses a method for preparing a 3D printed diabetic foot insole, which comprises the following steps: checking the condition of the patient; 3D scanning the sole of the patient's foot to obtain 3D scanning data of the sole of the foot; scanning the bottom surface of the insole used by the patient daily using a 3D scanner to obtain 3D scanning data of the bottom surface of the insole; use 3D Max and netfabb software to import the 3D scanning data of the bottom of the foot and the 3D scanning data of the bottom surface of the insole to generate a 3D digital file of the diabetic foot insole model. , to obtain the final 3D diabetic foot insole data; use 3D printing machine to print according to the final 3D diabetic foot insole data, obtain 3D diabetic foot insole semi-finished products; finely process the 3D diabetic foot insole semi-finished products, and obtain 3D diabetic foot insole finished products. The 3D printed diabetic foot insole is comfortable to wear, saves materials, and has good use effect.

Description

technical field [0001] The invention relates to the technical field of diabetic foot insoles, in particular to a preparation method and application of 3D printed diabetic foot insoles. Background technique [0002] Diabetic foot is one of the most serious complications of diabetic patients due to lower extremity infection, ulcer formation and / or destruction of deep tissues due to neuropathy and peripheral vascular disease. Among them, diabetic foot ulcers are the main cause of lower limb amputation in diabetic patients. Studies have shown that diabetic foot accounts for 12.4% of hospitalized diabetic patients, and the amputation rate is 7.3%. More than 15% of people with diabetes will develop foot ulcers in their lifetime. Between 14% and 24% of patients with foot ulcers require amputation. [0003] Abnormal changes in plantar pressure and changes in gait stability are a factor in the pathogenesis of foot ulcers. The pressure on each part of the normal human foot is from ...
