Description

一种医用脑出血软通道引流专用电钻钻头

技术领域

[0001] 本发明涉及一种医用脑出血软通道引流专用电钻钻头。

背景技术

[0002] 脑出血是一种高发疾病,其致死致残率高。微创软通道引流技术是一项简单有效实用的技术,目前已在全国大多数县级以上医院得到普及。但目前各家医疗单位所采用的都是手动T型钻头。该钻颅设备由于颅骨骨质坚硬,手钻易在颅骨表面滑动,偏离原设计的入颅点,而且手钻钻颅相当费力,需要医生用力顶住颅骨,会使患者相当痛苦导致躁动,不利于手术,并且手术时间长,可能延误抢救。

发明内容

[0003] 为解决上述现有的缺点,本发明的主要目的在于提供一种实用的医用脑出血软通道引流专用电钻钻头,能够有效加快手术进程,为抢救赢得时间,减轻手术医生的体力过多消耗,并且减轻患者的不适感。

[0004] 为达成以上所述的目的,本发明的一种医用脑出血软通道引流专用电钻钻头采取如下技术方案:

[0005] 一种医用脑出血软通道引流专用电钻钻头,包括螺旋状钻头、带螺纹的钻身、三棱状钻尾和限位器,其 特征在于,所述限位器为空心状,限位器内设置螺纹,所述带螺纹的钻身上设置限位器,带螺纹的钻身一端设置螺旋状钻头,另一端设置三棱状钻尾。

[0006] 所述限位器分两部分安装,与带螺纹的钻身构成螺栓、螺母关系。

[0007] 所述螺旋状钻头设置为直径3毫米、5毫米和7毫米三种规格。

[0008] 采用如上技术方案的本发明,具有如下有益效果:

[0009] 能够有效加快手术进程,为抢救赢得时间,减轻手术医生的体力过多消耗,并且减轻患者的不适感。

附图说明

[0010] 图1为本发明的结构示意图。

具体实施方式

[0011] 为了进一步说明本发明,下面结合附图进一步进行说明:

[0012] 如图1所示,本发明的一种医用脑出血软通道引流专用电钻钻头,包括螺旋状钻头1、带螺纹的钻身2、三棱状钻尾3和限位器4,限位器4为空心状,限位器4内设置螺纹,带螺纹的钻身2上设置限位器4,带螺纹的钻身2 —端设置螺旋状钻头1,另一端设置三棱状钻尾3。限位器4分两部分安装,与带螺纹的钻身2构成螺栓、螺母关系,目的是为了加强限位作用,不会导致由于钻头钻洞时,限位器4发生移位。螺旋状钻头I设置为直径3毫米、5毫米和7毫米三种规格。[0013] 本发明的一种医用脑出血软通道引流专用电钻钻头,使用时先测量拟穿刺处颅骨及头皮厚度。根据拟置入引流管的大小选择不同规格的钻头。将限位器尾段部分从尾端方向套入,套上螺纹向头端方向顺时针上螺丝。再将头端部分限位器从钻头方向套入,再次逆时针方向向尾端方向上螺丝。根据术前测量的颅骨及头皮厚度,在钻头方向预留同样的长度。将限位器两部分接触在一起。将尾端三棱柱状部分与医用电钻连接,并锁定。本装置结构简单、实用、可靠、造价低廉。能够有效加快手术进程,为抢救赢得时间,减轻手术医生的体力过多消耗,并且减轻患者的不适感。适合在各类各级医院推广使用。在脑出血微创软通道钻孔引流术中具 有广泛应用前景。
