头颅固定设备在颅脑解剖学实验教学和研究方面具有非常重要的应用价值。笔者参考了有关学者制作的头颅固定装置[1-2],并根据我院人体解剖学实验教学和科研工作的实际
需要,制作了一款多功能颅脑解剖操作台(图1),应用效果良好,现介绍如下。1 制作材料的选择
根据设备使用的特殊性,首先选择具有抗压强度、耐酸碱腐蚀,易于清洗和轻便的材料,故选择不锈钢或铝材等为宜。

2 主要组成部件及功能
2.1 十字手拧螺丝、锥形固定杆和弓形固定杆
十字手拧螺丝的头端为十字形,用于可调节部件的固定;锥形固定杆的头端为四棱锥形,有2个,位于左右两侧,专门对准外耳门位置固定;弓形固定杆的头端为弓形,可双向活动,用十字手拧螺丝固定,seifert
共有3个,颅侧2个,分列两边,用于颅额、顶、枕部位置固定,尾侧1个,位于正中,用于固定下颌。
2.2 升降杆和调节块
升降杆为中央镂空;调节块中央打孔,可置于升降杆内,能上下移动;两侧为十字手拧螺丝。固定杆可插入调节块中央孔,借助调节块调节高度,十字手拧螺丝固定。
2.3 操作台台面及底槽
操作台面为铝质材料,台面操作区下沉0.5 cm ,用于辅助脑组织切片时厚度测量,可防止在操作中福尔马林液外溢。台面操作区向半圆凹陷处倾斜,半圆区凹陷处最低点为引流孔,与底槽相通,液体可引流至底槽,减少刺激。在台面操作区3侧(左、右侧及尾侧)激光打码,设置标尺,实验过程中不需借用测量工具。台面纵向2侧有轨道,移动块中央打孔,可沿轨道移动,十字手拧螺丝固定;横向2侧为位置固定的3个嵌入块,嵌入块中央打孔;升降杆可插入移动块和
嵌入块中央孔。底槽为不锈钢材料,空腔接引流孔流入的液体;操作完成后收纳各部件,操作台两侧设有嵌入式把手,用于实验中搬动,尾侧设有可折叠把手,便于搬运时手提。底槽以铰链与台面相连,安全扣锁紧。
3 设备使用情况
此设备操作简单,使用方便,用于开颅取脑及头面部解剖的头颅固定,颅脑结构的测量,脑组织切片。目前主要适用五年制、八年制临床医学局部解剖学、研究生头颈部解剖学、中枢神经解剖学课程。
