3D printing technology based limb orthosis for stroke patient and manufacturing method

Abstract

The invention provides a 3D printing technology based limb orthosis for a stroke patient and a manufacturing method. The limb orthosis comprises a finger separating plate and a foot support, wherein the finger separating plate comprises a plate body in a shape of a hand with fingers stretched, a thumb slot, palm finger slots and a palm groove are formed in the upper surface of the plate body, multiple first air holes are formed in the bottom of each of the thumb slot, the palm finger slots and the palm groove, and bandage penetrating holes are formed on two sides of the plate body and between the adjacent two palm finger slots; the foot support comprises a main body, the main body comprises a first sheet part and a second sheet part, and the first sheet part and the second sheet part integrally form an approximate 'L'-shaped structure. The 3D printing technology based limb orthosis is simple in structure, spasm and contracture of fingers and feet in the limb rehabilitation process of the stroke patient can be prevented and treated, the limb orthosis manufactured with a 3D printing technology can enlarge the attaching area of limb skin, reduces the local pressure and improves the comfort, wearing of the patient is better facilitated, the utilization rate of the orthosis is increased, and the limb rehabilitation effect is improved.

Description

technical field [0001] The invention relates to a rehabilitation medical correction device, in particular to a limb orthosis for stroke patients based on 3D printing technology and a manufacturing method. Background technique [0002] 3D printing is based on digital model files. First, it is modeled by computer modeling software, and then the built three-dimensional model is "divided" into layer-by-layer sections, and the printer is instructed to use powdered metal or plastic and other bondable materials. The technology of constructing objects by printing layer by layer. Commonly used materials are nylon, gypsum, aluminum, titanium alloy, stainless steel, silver-plated, gold-plated, rubber and other materials. At present, there are four commonly used printing methods: selective laser sintering technology, fused deposition modeling technology, multi-nozzle molding technology and three-dimensional printing. [0003] Most stroke patients have limb hemiplegia. Due to the lack ...

AI Technical Summary

Problems solved by technology

However, the application of 3D printing in medicine in China is currently more than that of implantation (such as filling after spinal surgery), and there are few reports on the application of limb orthoses. The reason is that the reconstruction process of 3D limb scanning and modeling is time-consuming. The selection of printing materials and printing materials is complicated. Therefore, it is of great scientific, practical and practical significance to carry out research on the application of 3D printed orthotics to stroke rehabilitation patients, to promote the application in stroke rehabilitation, and to improve the recovery of limb functions of patients. urgency
