3D-printed hallux valgus orthopedic insole

Abstract

The invention provides a 3D-printed hallux valgus orthopedic insole. The insole comprises a 3D-printed insole body and a 3D-printed correction structure for correcting hallux valgus; the correction structure comprises a finger-separated finger sleeve, a first force application part and a second force application part; the finger-separated finger sleeve is arranged on the insole body and corresponds to a thumb area; the finger-separated finger sleeve comprises a finger sleeve main body and a finger sleeve force application wall; the finger sleeve main body is used for fixing the thumb of a patient; and the finger sleeve force application wall is used for separating a first phalanx from a second phalanx and forming a reaction force on the first phalanx and the second phalanx. The insole is simple in structure and convenient to use; the comfort degree and the fit degree are improved through personalized customization; and the silica gel material is used, so that the softness is good, andthe foot skin is protected from being extruded and abraded. Meanwhile, the insole has good correction effect on the first phalanx, a first metatarsal bone and metatarsal bone joints, and can apply accurate correction force. In addition, the insole can be placed in normal shoes, does not influence walking, is suitable for a patient to walk and stand, and is comfortable and beautiful.

Description

Technical field [0001] This application relates to the field of foot orthopedic devices, in particular to a 3D printed hallux valgus orthopedic insole. Background technique [0002] Hallux valgus is a relatively common foot deformity, with an incidence rate of 20-50%, among which the prevalence of females is about 9-10 times that of males. Conservative treatment by wearing a foot orthosis is the first choice for patients. At present, hallux valgus orthoses are mostly mass-produced, failing to meet the individual characteristics of the feet of different patients, resulting in low wearing comfort and poor orthopedic effects. [0003] There are many types of existing orthoses. According to different orthopedic principles, hallux valgus orthoses can be divided into two categories: the first type of orthosis applies force on the outside of the first toe, which will cause the gap between the first toe and the second toe. The gap is too large; the second type of orthosis that applies fo...

AI Technical Summary

Problems solved by technology

However, due to the limitation of flexible materials, the correction force is limited, so it is not suitable for patients with severe hallux valgus

Orthotics that use hard materials to apply force usually have a low degree of matching with the shape characteristics of the individual foot surface, resulting in excessive local pressure and induced pain

[0004] Therefore, the existing orthotics generally have the characteristics of mass production, popularization, and poor curative effect. These orthotics for hallux valgus correction cannot meet the patient's individual foot shape characteristics, and lack support for the patient's arch part, resulting in the medial forefoot Excessive local pressure, inducing pain
