Abrégé
(EN)
The invention provides a joint gasket prosthesis and a joint prosthesis with the joint gasket prosthesis. The joint gasket prosthesis comprises an elastic gasket arranged between a first skeleton anda second skeleton which are used for forming a joint; the elastic gasket comprises an elastic substrate and a plurality of joint fluid passages; the elastic substrate is provided with a first contactsurface facing to the first skeleton and a second contact surface facing to the second skeleton; the plurality of joint fluid passages are distributed in the elastic substrate and are communicated with the first contact surface and the second contact surface; the plurality of joint fluid passages are arranged in a preset mode, so that the hardness of the elastic substrate is gradually increased from the center to the edge, and the elasticity of the elastic substrate is gradually reduced from the center to the edge. According to the technical scheme, the problems that in the prior art, the contact area between the joint skeleton and the joint gasket prosthesis cannot be ensured, and the phenomena of overgreat local pressure intensity and serious abrasion of the joint gasket prosthesis can probably occur, so that the service life of the joint prosthesis of a patient is short are effectively solved.

本发明提供了一种关节垫片假体及具有其的关节假体,其中,关节垫片假体包括:设置在形成关节的第一骨骼和第二骨骼之间的弹性垫片,弹性垫片包括:弹性基体,具有朝向第一骨骼的第一接触面和朝向第二骨骼的第二接触面;多个关节液通道,分布在弹性基体中并连通第一接触面和第二接触面,多个关节液通道的按照预定方式布置以使弹性基体的硬度从中心向边缘逐渐升高并且弹性基体的弹性从中心向边缘逐渐降低。本发明的技术方案有效地解决了现有技术中关节骨骼与关节垫片假体之间接触面积无法保证,可能出现局部压强过大、关节垫片假体磨损严重,导致患者关节假体使用寿命短的问题。
