Controlled cortical injury animal model manufacturing device mechanical collision system

Abstract

The invention discloses a controlled cortical injury animal model manufacturing device mechanical collision system, which comprises an experiment platform, an animal fixing device, a support frame, anelectromagnetic push rod, an collision needle and a control box, wherein the animal fixing device is arranged on the experiment platform; one end of the support frame is connected with the animal fixing device; the other end of the support frame is connected with the electromagnetic push rod; the top end of a push rod of the electromagnetic push rod is connected with the collision needle; the control box comprises a control panel and a control circuit; the control panel and the electromagnetic push rod are respectively and electrically connected with the control circuit; the control box is provided with an external power supply. The collision is implemented through the electromagnetic push rod; the collision intensity and the collision compression time can be precisely regulated and controlled; the control is convenient; craniocerebral trauma animal models at different degrees can be manufactured.

Description

technical field [0001] The invention relates to an experimental device, in particular to a mechanical impact system of a controlled cortical injury animal model making device. Background technique [0002] In the animal impact experiment, it is necessary to fix the head of the animal under anesthesia, and then use the impact device to quickly impact the animal's cerebral cortex. [0003] The existing striking device is a pendulum-driven hydraulic transmission striking device, and the speed and strength of the striking can be adjusted by replacing the pendulum with different masses and / or releasing the pendulum from different heights. [0004] However, the method of hitting with hydraulic transmission has poor stability, and cannot guarantee the same force of each impact under the same conditions, and the accuracy of the experiment is low; moreover, the pressing time of the firing pin cannot be controlled during the impact, so it cannot meet the higher requirements of the exp...
