Abstract

本发明涉及一种医用工具，尤其涉及一种折断起子。这种折断起子，包括起子杆和弹片，所述的起子杆一端设有起子槽，所述的弹片设置在起子杆上，所述的起子槽与弹片贯通。在手术过程中，通过弹片的弹力将钉子固定于弹片与起子杆之间，当折断钉子后，折断部分会自动脱落到起子槽内，方便快速取出。

Description

折断起子
技术领域
本发明涉及一种医用工具，尤其涉及一种折断起子。
背景技术
目前医院所用的折断起子是采用两个弹片固定钉子，在手术中通过两个弹片固定钉子并将钉子折断，由于其接触面积大，很难去除钉子的折断部分，而且去除折断部分的钉子需要耽误很长的时间，造成手术中使用此工具的繁琐及提高了手术的风险。
发明内容
本发明要解决的技术问题是：目前使用的折断起子将钉子折断后，钉子的折断部分难以去除，提供一种折断起子。
为了克服背景技术中存在的缺陷，本发明解决其技术问题所采用的技术方案是：这种折断起子，包括起子杆和弹片，所述的起子杆一端设有起子槽,所述的弹片设置在起子杆上,所述的起子槽与弹片贯通。
本发明的有益效果是：在手术过程中，通过弹片的弹力将钉子固定于弹片与起子杆之间，当折断钉子后，折断部分会自动脱落到起子槽内，方便快速取出折断的钉子。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图；
图2是本发明的主视图；
其中：1、起子杆，2、弹片，3、起子槽。
具体实施方式
如图1、2所示一种折断起子，包括起子杆1和弹片2，所述的起子杆1一端设有起子槽3,所述的弹片2设置在起子杆1上,所述的起子槽3与弹片2贯通。在手术过程中，通过弹片2的弹力将钉子固定于弹片2与起子杆1之间，由于弹片2与起子杆1之间接触的面积很小，当钉子折断后，折断后的钉子会脱落到起子槽3内，从而能够很方便的取出折断的钉子，方便之后使用。

Claims (1)

1.一种折断起子，包括起子杆(1)和弹片(2)，其特征在于：所述的起子杆(1)一端设有起子槽(3),所述的弹片(2)设置在起子杆(1)上,所述的起子槽(3)与弹片(2)贯通。
