假体椎间盘以及其使用方法

种假体椎间盘和使用这些盘的方法。本发明的假体盘包括被个可压缩的芯件分开的上和下端板。该假体盘包括单件、两件、三件和四件结构。本发明的假体盘呈现出在竖直方向上的刚硬度、扭曲刚硬度、在弧矢平面中的弯曲刚硬度以及在前平面中的弯曲刚硬度，其中可以通过调节盘的部件独立地控制这些特点的程度。这些假体盘的几个实施例的端板与芯件之间的对接机构使得植入的外科手术可以非常容易进行。 Prosthetic intervertebral discs and methods for using the same are described. The subject prosthetic discs include up...

Summary:种假体椎间盘和使用这些盘的方法。本发明的假体盘包括被个可压缩的芯件分开的上和下端板。该假体盘包括单件、两件、三件和四件结构。本发明的假体盘呈现出在竖直方向上的刚硬度、扭曲刚硬度、在弧矢平面中的弯曲刚硬度以及在前平面中的弯曲刚硬度，其中可以通过调节盘的部件独立地控制这些特点的程度。这些假体盘的几个实施例的端板与芯件之间的对接机构使得植入的外科手术可以非常容易进行。 Prosthetic intervertebral discs and methods for using the same are described. The subject prosthetic discs include upper and lower endplates separated by a compressible core member. The prosthetic discs described herein include one-piece, two-piece, three-piece, and four-piece structures. The subject prosthetic discs exhibit stiffness in the vertical direction, torsional stiffness, bending stiffness in the saggital plane, and bending stiffness in the front plane, where the degree of these features can be controlled independently by adjusting the components of the discs. The interface mechanism between the endplates and the core members of several embodiments of the described prosthetic discs enables a very easy surgical operation for implantation.
