Abstract

本实用新型涉及砧镫关节分离刀,应用于耳科分离砧骨与镫骨之间的关节。它由手柄(1)、刀杆(3)、刀刅片(5)组成;刀杆(3)一端与手柄(1)一体相连,另一端与刀刅片(5)一体相连;刀刅片(5)的平面与刀杆(3)之间的夹角95°~105°;刀刅片(5)外端呈椭圆形,里端逐渐内收最后与刀杆(3)相连,边缘带锋刅。具有施予作用力的大小容易操控,切割顺手,结构简单的优点。

Description

砧镫关节分离刀
技术领域
本实用新型涉及砧镫关节分离刀,应用于耳科分离砧骨与镫骨之间的关节。
背景技术
镫骨手术时须把砧骨与镫骨之间的关节分离开,才能推到镫骨,目前尚无砧镫关节分离刀,只有用小钩子去分离。钩切时,因粘膜面粗糙而无法精确确定切割位,常常造成镫骨上方的小关节盘也被勾切下来。
发明内容
本实用新型的目的在于克服上述现有技术中的不足之处,提供一种精确确定切割位的砧镫关节分离刀。
本实用新型的目的可以通过下述技术方案达到:砧镫关节分离刀,其特征是由手柄、刀杆、刀刅片组成;刀杆一端与手柄一体相连,另一端与刀刅片一体相连;刀刅片的平面与刀杆之间的夹角95°~105°;刀刅片外端呈椭圆形,里端逐渐内收最后与刀杆相连,边缘带锋刅。
本实用新型具有如下优点:
1、施予作用力的大小容易操控;
2、切割时外挑或内钩顺手;
3、结构简单。
附图说明
附图是本实用新型结构示意图。
图中1是手柄,3是刀杆,5是刀刅片。
具体实施方式
本实用新型下面结合附图作进一步的说明。砧镫关节分离刀,由手柄(1)、刀杆(3)、刀刅片(5)组成;刀杆(3)一端与手柄(1)一体相连,另一端与刀刅片(5)一体相连;刀刅片(5)的平面与刀杆(3)之间的夹角95°~105°;刀刅片(5)外端呈椭圆形,里端逐渐内收最后与刀杆(3)相连,边缘带锋刅。
制作时,手柄(1)采用φ5mm的内接正六边形,长度70mm;刀杆(3)长105mm,锥台状,从与手柄(1)衔接处逐渐缩小至φ2mm再与刀刅片(5)衔接。刀刅片(5)厚度0.5mm,与整个刀杆(3)呈100°角。使用时,手握手柄(1),让刀刅片(5)朝外,置被切割的砧镫关节于右侧,向右外方向挑用力,或者置被切割的砧镫关节于左侧,向内钩割用力即可把关节分离。
