Abstract

一种颅骨钻孔脑保护器,涉及医疗器械技术领域,其特征在于:在横“U”型槽(1)上唇(2)的螺孔内有一空心螺钉(5);本实用新型能准确地控制钻头的钻入深度,有效地防止钻头钻入脑组织。

Description

一种颅骨钻孔脑保护器
本实用新型涉及医疗器械技术领域。
目前,颅骨钻孔由术者凭经验和感觉掌握钻头钻入的深度,手术时钻头容易钻入脑组织,破坏大脑的组织结构,影响大脑的正常功能。
本实用新型的目的是设计一种颅骨钻孔脑保护器,能够准确地控制钻头的钻入深度,防止钻头钻入脑组织,从而克服现有技术存在的上述不足。
本实用新型的目的是以如下技术方案实现的:在横“U”型槽上唇的螺孔内有一空心螺钉,螺钉的上端有向两侧伸出的耳状手柄,螺钉的下端面粗糟,将颅骨嵌入“U”型槽的下唇和螺钉的下端面之间,拧紧螺钉,将颅骨牢固地固定,钻头通过空心螺钉的空腔在颅骨上钻孔,钻头到达“U”型槽的下唇时,完成钻孔。
本实用新型对颅骨固定牢固,钻头被固定在“U”型槽内活动,防止了钻头由于操作的原因进入脑组织。
附图是本实用新型的结构示意图;
下面结合附图对本实用新型作进一步说明:在横“U”型槽1上唇2的螺孔内有一空心螺钉5,螺钉5的上端有向两侧伸出的耳状手柄4,螺钉5的下端面6粗糙,将颅骨嵌入“U”型槽1下唇3和螺钉5下端面6之间,拧紧螺钉5,将颅骨牢固地固定,钻头通过空心螺钉5的空腔7在颅骨上钻孔,钻头到达“U”型槽1下唇3时,完成钻孔;本实用新型结构简单,操作方便,能够有效地保护脑组织免受钻头的伤害。
