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.
