Pinpoint精确皮层撞击器专为医学研究人员设计,目的是在大小鼠模式动物身上诱发和复制颅脑和脊髓损伤。主要用于大小鼠脊髓损伤(spinal injury)方面的研究,该仪器可评估潜在的脊髓损伤结构机制,产品具有控制精准、功能强大和灵活精确、极好的有效性和重复性,其驱动电机是通过计算机上的软件进行控制和操作,允许用户输入相同的碰撞参数,并为每个实验确定相同的撞击位置,使用Pinpoint,您可以进行精确,受控制和可重复性的撞击。

 

部分组件说明

线性驱动电机及撞击杆

该驱动电机是一个直线型的结构,包括电机和操纵臂,撞击时,电机是固定的,动的只是操纵臂,这使得电机能够更有力更耐用的驱动操纵臂。

 

撞击头(Impact Tips)

撞击头在撞击过程中直接接触目标动物,有圆头的或直角的,用于TBI或SCI的研究,另外,撞击头有7种规格(1 到 5mm范围内:1、1.5、2、2.5、3、4、5 mm)。也可以根据用户的要求定制特殊规格的撞击头。

 

 

铰链支撑臂Articulated Support Arm (ASA)

铰接支撑臂是一个机械臂驱动电机,提供360˚活动范围,支撑臂有两种尺寸,中型和大型,增加了实验的灵活性,大型ASA适合较大点的动物实验。

 

 

 

控制单元(Control Unit )

控制单元是连接软件和驱动电机的接口单元,用于信号传递和补充电能。

大小鼠脊髓适配器

大小鼠脊髓适配器主要用于精确的脊髓定位操作,与标准脑立体定位仪或U型脑定位仪基座配套使用,脊柱是由四个独立的横突夹,以及棘突夹构成,横突夹旨在减少对动物的创伤,同时提供一动不动的固定支持。

 

 

 

 

 

 

PinPoint™ 使用GUI图形用户友好界面软件,易于操作,直观性好,可安装在一个标准的PC机上或笔记本电脑上,点击式应用功能允许使用者:可自由的调节撞击速度、深度和撞击后的保持时间、控制臂的垂直运动、启动撞击,软件自动记录主要的数据,可浏览、保存和输出数据,撞击结果还可以以图形形式表现,确保优良的品质,操作系统平台支持Win95,2000,XP等。

 

 

产品配置

系统的组成元件是PinPoint的强大功能和多功能性背后的驱动力,尤其重要的是驱动电动机、撞击头、控制单元、和驱动电机安装适配器、铰链支撑臂(ASA)、支撑臂安装适配器、大鼠脊髓适配器或小鼠脊髓适配器、U型脑立体定位仪基座。

1.  微处理器控制;
2.  完整的报警接触传感器,当撞击头接触到头部的时候,驱动电机和撞击杆自动建立参考点;

3.  传感器采用了视觉和听觉的指示器来提醒使用者接触的发生;

4.  听觉指示器可选操作,可以按下位于控制单元前面板上的电源开关来关闭它,同时带有音量调节旋钮;

5.  简单易用的GUI图形用户友好界面软件 ;

6. 撞击速度可调范围:0.1-4m/s ;
7. 撞击深度可调范围:0-15mm;
8. 撞击后的保持时间可调范围:0-5000(毫秒级)

9.  配备有七种撞击头尺寸(1 到 5mm范围内:1、1.5、2、2.5、3、4、5 mm);

10. 软件自动记录主要的数据,可浏览、保存和输出数据,撞击结果还可以以图形形式表现;

11. 操作系统平台支持Win95,2000,XP等。

12. 可360度范围旋转;

13. 多型号配置选择;

主要用于大小鼠动物模型的颅脑损伤和脊髓损伤的撞击。
