Personalized-wearing prosthesis and manufacturing method thereof

Abstract

The invention discloses a personalized-wearing prosthesis, comprising a thigh prosthesis, a shank prosthesis, a foot prosthesis, a first spring and a second spring. The thigh prosthesis comprises a flexible upper portion and a rigid lower portion with a curved surface, the upper portion of the thigh prosthesis is provided with a wearing cavity, and the lower portion thereof is provided with a first shaft; the upper portion of the shank prosthesis is provided with a shank front guard plate, a shank back guard plate, a left-hand support and a right-hand support, the first shaft is mounted on theleft-hand support and the right-hand support, and the first spring is arranged between the thigh prosthesis and the shank prosthesis; the upper portion of the foot prosthesis is provided with a footfront guard, a foot back guard, a left bearing frame and a right bearing frame, a second shaft is arranged on the lower portion of the shank prosthesis and mounted on the left bearing frame and the right bearing frame, and a second bearing is arranged between the shank prosthesis and the foot prosthesis. The personalized-wearing prosthesis has the advantages of high wearing comfort, good shock resistance and low cost. The invention further discloses a manufacturing method of the personalized-wearing prosthesis.

Description

technical field [0001] The invention relates to the field of artificial limbs, in particular to a 3D printing-based personalized wearable artificial limb and a manufacturing method thereof. Background technique [0002] 3D printing, also known as additive manufacturing, is a new type of manufacturing method that began in the 1980s. After more than 30 years of development, the technology has matured and is widely used in aerospace, military, medical and other fields. With the continuous breakthrough of materials, it is often used to make models in the fields of mold manufacturing and industrial design, and then gradually used for direct manufacturing of some products. There are already parts printed using this technology, which can now be used for 3D printing. The materials are not limited to various hard plastics and metals, but more and more materials with different properties have emerged, including flexible materials. This technology is widely used in jewelry, footwear, i...

Problems solved by technology

[0004] At present, domestic prosthetics still adopt the old-fashioned prosthetic production technology, mainly using alloy steel materials, which are heavy in weight, and mostly use the mechanical design of connecting rods and spring mechanisms, which makes the existing prosthetics complex in structure, uncomfortable to wear, and heavy in weight. , poor anti-seismic effect and poor experience

[0005] Although foreign prosthetics have used pneumatic, hydraulic, and computer intelligently controlled prostheses, they are expensive
