Abstract

The invention relates to an individualized meniscus forming method based on 3D printing, a meniscus, a meniscus die and a manufacturing method. The forming method includes the steps that knee joint image data of an individual are acquired; the acquired knee joint image data are guided in medical reverse software, and a meniscus three-dimensional model is obtained after processing is completed; themeniscus three-dimensional model is guided in reverse engineering software, a model triangular patch is optimized and guided in design software for turnover operation, and a die model is manufactured; a transparent material is adopted for 3D printing, and a physical transparent meniscus die is obtained; and light-sensitive hydrogel is poured into the machined meniscus die, curing and forming arecarried out through ultraviolet or infrared or visible light irradiation, and the individualized meniscus is obtained. The meniscus three-dimensional model is established based on the knee joint imagedata of the individual, the transparent die is designed and printed through 3D printing, the light-sensitive hydrogel is injected, curing and forming are completed after light irradiation, the stentprecision is improved, and the mechanical strength is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a 3D printing-based personalized meniscus forming method, a meniscus prepared by the method, a meniscus mold used and a method for making the mold. Background technique [0002] The meniscus is located in the knee joint, between the femoral condyle and the tibial plateau. It is an important part of the knee joint. It has important functions such as load transmission, shock absorption, proprioception, lubrication and nutrition of the joint. stability and coordination, increase the contact area between tibia and femur, and reduce the contact stress between cartilage. Meniscus tear is one of the most common sports injuries. Total meniscectomy reported in 1948 was generally considered to be the only effective surgical method for knee joint sports injuries; Alternative to total meniscectomy; however, meniscectomy will result in reduced contact area and increased contact press...
