3D-printing-based customized external foot fixation protector

Abstract

The invention discloses a 3D-printing-based customized external foot fixation protector. The 3D-printing-based customized external foot fixation protector comprises protectors at left and right portions, dual-dovetail-groove fasteners distributed on the edges of the protectors and air vents distributed in the surfaces of the protectors; the protector is realized through a 3D printing technology on the basis of CT data of a foot of a patient and is printed as left and right portions crossing an ankle, and the protectors at the left and right portions are fixed through the dual-dovetail-groove fasteners. The 3D-printing-based customized external foot fixation protector can be optimally customized aiming at different wounds of different patients, has the advantages of light weight, good air permeability, convenience in installation, simplicity in use and reliable fixation, facilitates the rehabilitation activities of the patient, prevents skin aging, itching and the like, and greatly improves the comfort of the patient during rehabilitation.

Description

technical field [0001] The invention relates to a 3D printing-based customized foot external fixation protector, which belongs to the field of engineering technology and medical rehabilitation. Background technique [0002] With the widespread use of vehicles, traffic accidents are becoming more and more frequent, and patients with trauma orthopedics are increasing day by day. Fracture is the most common disease in trauma orthopedics, and reduction, fixation, and healing are the trilogy of fracture treatment. Good fixation not only consolidates the reduction effect, but also promotes the speed and quality of healing. Brake, relieve pain, relieve the pain of the wounded, prevent the aggravation of the injury, prevent shock, protect the wound, prevent infection, and facilitate transportation. [0003] As an important lower limb of the human body, the foot plays the roles of lower limb support, walking and so on. Its movement is flexible, the range of movement is large, the ...

Problems solved by technology

However, the traditional auxiliary material such as gypsum is relatively bulky, heavy, poor ventilation performance, itching or odor, which is not conducive to the rehabilitation activities of the feet in the middle and late stages of treatment, causing discomfort to the human body, leading to muscle function degradation and skin aging.

In addition, after the plaster is set and fixed, it will not deform with the change of the muscle tissue of the affected area. When the swelling or muscle atrophy of the affected area disappears, the affected area will be separated from the plaster, and sometimes it cannot be effectively fixed.
