Abstract

一种带锁髓内钉磁力探针，是对现有髓内钉探针的改进，其结构特点是在针体的前端还安装有一块磁铁。使用时，本实用新型前端的磁铁伸入到钉孔位置，与髓内钉远端钉孔定位装置的瞄准指示器磁铁配合，利用两块磁铁相互吸引确定钉孔位置，操作非常方便，瞄准定位准确，可以大大减小手术难度，缩短手术时间。

Description

带锁髓内钉磁力探针
所属技术领域
本实用新型涉及骨科用医疗器械技术领域，特别是涉及一种插装在带锁髓内钉内的探针。
背景技术
目前，带锁髓内钉内固定技术在临床上已得到普遍应用，但髓内钉远端钉孔的定位是手术中很难操作的技术问题，一直未能得到很好地解决，由于钉孔定位不准确而造成钻孔失败的现象时有发生，从而延长手术时间，增加病人痛苦，影响手术效果。为提高钻孔准确性，通常采用X光定位，不仅操作复杂，还会对病人和医生造成辐射损害。现有的髓内钉探针仅是一根细长的金属杆，不能对髓内钉远端钉孔进行准确定位。
发明内容
本实用新型的目的就是针对现有技术的不足，提供一种带锁髓内钉磁力探针，以便于对带锁髓内钉远端钉孔瞄准定位，从而减小手术难度，提高手术效果。
本实用新型是对现有髓内钉探针的改进，其结构特点是在针体的前端安装有一块磁铁。
本实用新型针体的后端带有向上的弯折。针体的后部装有限位块或/和带有刻度。
使用时，本实用新型前端的磁铁伸入到钉孔位置，与髓内钉远端钉孔定位装置的瞄准指示器磁铁配合，利用两块磁铁相互吸引确定钉孔位置，操作非常方便，瞄准定位准确，可以大大减小手术难度，缩短手术时间，减轻病人痛苦，提高手术质量。本实用新型结构简单，医生很容易掌握操作方法，便于推广普及。
附图说明
图1为本实用新型的主视图，示出了其整体结构。
具体实施方式
在附图所示实施例中，本实用新型同样具有细长的针体1，在针体1的前端安装有磁铁2，磁铁2装在针体1上的长孔中，由装在针体端部的螺钉3固紧。针体1的后端带有向上的弯折5，弯折端可以插在髓内钉远端钉孔定位装置手柄的小孔中，以对正磁铁2的磁极方向。针体1的后部装有限位块4或/和带有刻度，用以限定磁铁2的插入深度，使其与钉孔对准。
