Abstract

本发明公开了一种植入式关节限位装置，所述的植入式关节限位装置包含一弧形的固定基片，所述的固定基片的底部两侧分别设有一长条状的限位基片，所述的限位基片的末端分别设有一向内弯曲的限位挡片，所述的限位基片之间形成一半开放的限位滑槽。本发明的植入式关节限位装置利用固定基片底部两侧的长条状的限位基片和限位基片之间的限位滑槽，可以将钢钉限制在限位滑槽内，并限制钢钉的活动范围，防止病人因动作过大而导致钢钉脱落，效果明显，实用性强。

Description

一种植入式关节限位装置
技术领域
 本发明涉及一种医疗器械，更确切地说，是一种植入式关节限位装置。
背景技术
在患者进行关节手术而打上钢钉后，由于关节的活动范围较大，钢钉极容易发生脱落，只能再次手术，给患者带来不便和痛苦。
发明内容
 本发明主要是解决现有技术所存在的技术问题，从而提供一种植入式关节限位装置。
本发明的上述技术问题主要是通过下述技术方案得以解决的：
一种植入式关节限位装置，所述的植入式关节限位装置包含一弧形的固定基片，所述的固定基片的底部两侧分别设有一长条状的限位基片，所述的限位基片的末端分别设有一向内弯曲的限位挡片，所述的限位基片之间形成一半开放的限位滑槽。
作为本发明较佳的实施例，所述的植入式关节限位装置为不锈钢一体成型。
本发明的植入式关节限位装置利用固定基片底部两侧的长条状的限位基片和限位基片之间的限位滑槽，可以将钢钉限制在限位滑槽内，并限制钢钉的活动范围，防止病人因动作过大而导致钢钉脱落，效果明显，实用性强。
 
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明的植入式关节限位装置的立体结构示意图；
图2为图1中的植入式关节限位装置的立体结构示意图，此时为另一个视角；
图3为图1中的植入式关节限位装置的立体结构示意图，此时为另一个视角；
其中，
1、植入式关节限位装置；2、固定基片；3、限位基片；4、限位挡片；5、限位滑槽。
 
具体实施方式
下面结合附图对本发明的优选实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
如图1至图3所示，本发明的植入式关节限位装置1包含一弧形的固定基片2，该固定基片2的底部两侧分别设有一长条状的限位基片3，限位基片3的末端分别设有一向内弯曲的限位挡片4，限位基片3之间形成一半开放的限位滑槽5。
该植入式关节限位装置1为不锈钢一体成型。
不局限于此，任何不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
