Abstract

一种经皮钻颅手动旋转式螺旋形钻头,由钻柄、钻杆和旋钮组成,钻杆上带有一条螺旋边槽,通过钻头尖端,钻头尖端两侧带有两条齐头侧刃。本实用新型不易损伤脑血管,排屑顺利,使用方便省力。

Description

经皮钻颅手动旋转式螺旋形钻头
本实用新型属于一种采取人脑组织标本及进行脑血肿引流手术所使用的手钻。
目前,钻颅手术所使用的手钻有两种(见图2、图3),印圆锥形手钻和手摇钻头,这两种钻头存在下列缺点:图3所示钻头尖端易损伤脑膜血管而引起大出血,图2所示钻头不易排出骨屑。
本实用新型的目的在于提供一种不损伤脑血管、容易排屑的钻头。
本实用新型的目的是通过如下方式实现的:
该钻头由钻柄(1)、钻杆(2)和定位旋钮(3)组成,其中:钻杆(2)上带有一条螺旋边槽(4),定位旋钮(3)套在螺旋边槽(4)上,螺旋边槽通到钻头尖端,钻头尖端两侧带有两条齐头侧刃(5)。
本实用新型与现有技术相比,其钻尖不易损伤脑血管,同时切下的骨屑会顺利从螺旋边槽排出,使用省力方便。
下面结合附图对本实用新型作进一步描述:
图1是本实用新型的结构图
图2、图3是现有颅钻的结构图
在图1中:(1)钻柄;(2)钻杆;(3)定位旋钮;(4)螺旋边槽;(5)齐头侧刃。
图1即为本实用新型的一个实施例,该钻的材料为不锈钢,钻尖经淬火热处理,两条侧刃的夹角为150°,定位旋钮的销头卡在螺旋边槽内,钻杆总长20cm,螺旋边槽为双头,总长15cm。
