Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] The artificial meniscus support based on the fiber weaving structure of the present invention is composed of radial fibers 1 and hoop fibers 2 . The function of the radial fiber 1 is to resist shearing and tearing; the function of the hoop fiber 2 is to resist the hoop stress during load-bearing, such as figure 1 , figure 2 , image 3 shown.

[0024] The arrangement of the radial fibers 1 and the circumferential fibers 2 imitates the collagen fiber bundles inside the meniscus; wherein, the radial fibers 1 are fibers arranged circumferentially along the longitudinal section of the meniscus; and the radial fibers 1 are arranged along the transverse direction of the meniscus Arranged in multiple layers. The hoop fibers 2 are fibers arranged circumferentially along the cross section of the meniscus; and the hoop fibers 2 are arranged in multiple layer...

Abstract

The invention discloses an artificial meniscus scaffold based on a fiber braided structure. The three-dimensional braided meniscus scaffold uses a bionic idea and overcomes the defects that a traditional artificial meniscus is not enough in strength and short in service life. A braiding material, the braided structure and a braiding technical method are involved. The braiding material can be madeof biological materials such as collagen fibers, silk fibers and polycarbonate polyurethane fibers. The braided structure simulates the radial distribution and circumferential distribution of the collagen fibers of the biological meniscus, and the requirements of shearing force and annular force borne by the meniscus during knee joint motions are met. According to the braiding technical method, atraditional braiding method is used for single-layer braiding, pouring and shape setting, and then layer-by-layer accumulation series connection is conducted.

Description

technical field [0001] The invention relates to a novel meniscus support based on a fiber braided structure and a braiding process method. Background technique [0002] Meniscal injuries are one of the most common injuries of the knee. The meniscus is an important part of the most complex joint in the human body - the knee joint. It is located between the femoral condyle and the tibial plateau, one on the inner side and one on the outer side, both of which are crescent-shaped. During human movement, the meniscus moves along with the tibia. During the extension and flexion of the knee joint, the meniscus can be deformed to adapt to the anatomical shape of the knee joint, so the geometry of the knee joint and the coordination of movement are well maintained. Therefore, it has important functions such as bearing load, buffering load, stabilizing joints and lubricating joints. It also plays an important physiological role in protecting articular cartilage. [0003] Once the me...
