椎间盘假体持器
摘要：
本发明提供了一种椎间盘假体持器，用以抓取和移动椎间盘假体，椎间盘假体包括相对设置的第一终板和第二终板以及设置在第一终板和第二终板之间的髓核，椎间盘假体持器包括用以固定椎间盘假体的夹持部，夹持部包括两个相对设置的第一夹臂和第二夹臂，椎间盘假体能够夹设在第一夹臂和第二夹臂之间，第一夹臂上设置有第一保持部，第二夹臂上设置有第二保持部，第一保持部和第二保持部均能够伸入第一终板和第二终板之间的间隙中，以使第一终板和第二终板在移动过程中保持预定的相对位置。本发明的技术方案有效地解决了现有技术中椎间盘假体在置入时歪斜的问题。
摘要（英）：

The invention provides a holder for an intervertebral disc prosthesis. The holder is used for grasping and moving the intervertebral disc prosthesis. The intervertebral disc prosthesis comprises a first final plate, a second final plate and a nucleus pulposus, wherein the first final plate and the second final plate are arranged oppositely, and the nucleus pulposus is arranged between the first final plate and the second final plate; the holder for the intervertebral disc prosthesis comprises a clamping portion used for fixing the intervertebral disc prosthesis, the clamping portion comprises a first clamping arm and a second clamping arm, the first clamping arm and the second clamping arm are arranged in the opposite direction, the intervertebral disc prosthesis can be clamped between the first clamping arm and the second clamping arm, a first keeping portion is arranged on the first clamping arm, a second keeping portion is arranged on the second clamping arm, and the first keeping portion and the second keeping portion can extend into the gap formed between the first final plate and the second final plate so that the first final plate and the second final plate can keep preset opposite positions during movement. In the technical scheme, the problem that in the prior art, the intervertebral disc prosthesis inclines during implanting.
