Abstract

本发明公开了一种髌骨骨折内固定空心针，包括一一端设钉帽、一端设螺纹段的空心钉体，所述钉体两端管壁沿轴向均设有一凹槽，其特征在于，所述空心钉体由若干段彼此相互连接配合的分体钉体组成；所述若干段分体钉体采用螺纹连接组成，具体为：这若干段分体钉为隔一段两侧均为内螺纹连接部、隔一段两侧均为能和内螺纹连接部形成螺纹连接配合的外螺纹连接部构成。本发明采取若干个空心钉体采用螺纹连接的方式，实现了空心钉可随着不同患者的髌骨的尺寸而调节不同的长度，无须专门定制，从而将成本大大地降低了。

Description

一种髌骨骨折内固定空心针
技术领域
本发明涉及一种骨科医疗器械，尤其涉及一种髌骨骨折内固定空心针。
背景技术
目前用于髌骨骨折手术时，主要用内固定空心针将骨折部位进行连接固定，该固定针为空心、轴向带凹槽结构，便于金属线的固定，但空心针的长度是固定的，而每个患者的髌骨长度均有所不同，所以为了适应不同需求，只能采取定制的方法，这样显得非常麻烦，成本也随着增大。
发明内容
本发明就是针对上述问题，提出一种髌骨骨折内固定空心针，该空心针无须针对不同患者专门定制，成本大大下降。
为达到上述技术目的，本发明采用了一种髌骨骨折内固定空心针，包括一一端设钉帽、一端设螺纹段的空心钉体，所述钉体两端管壁沿轴向均设有一凹槽，所述空心钉体由若干段彼此相互连接配合的分体钉体组成。
作为优选，所述若干段分体钉体采用螺纹连接组成，具体为：这若干段分体钉的每一段均为左端设外螺纹连接部、右端设有能和外螺纹连接部形成配合连接的内螺纹连接部构成。
本发明采取若干个空心钉体采用螺纹连接的方式，实现了空心钉可随着不同患者的髌骨的尺寸而调节不同的长度，无须专门定制，从而将成本大大地降低了。
附图说明
图1所示的是本发明剖面结构示意图；
其中，1、钉帽；2、螺纹段；3、空心钉体；4、分体钉体；5、外螺纹连接部；6、内螺纹连接部。
具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细地说明。
由图1可知，一种髌骨骨折内固定空心针，包括一一端设钉帽1、一端设螺纹段2的空心钉体3，在空心钉体3两端管壁沿轴向均设有一凹槽，并且空心钉体由若干段彼此相互连接配合的分体钉体4组成。
本发明中，若干段分体钉体4采用螺纹连接组成，具体为：这若干段分体钉的每一段均为左端设外螺纹连接部5、右端设有能和外螺纹连接部5形成配合连接的内螺纹连接部6构成。
本发明中，若干段分体钉体4采用螺纹连接组成，具体为：这若干段分体钉的每一段均为左端设内螺纹连接部6、右端设有能和内螺纹连接部6形成配合连接的外螺纹连接部5构成。
本发明中，若干段分体钉体4采用螺纹连接组成，具体为：这若干段分体钉为隔一段两侧均为内螺纹连接部6、隔一段两侧均为能和内螺纹连接部6形成螺纹连接配合的外螺纹连接部5构成(具体见图1)。图中箭头所指方向为各段分体钉体4配合连接的方向。
