Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0016] Such as figure 1 , figure 2 As shown, the present invention includes a mechanical part and an electronic detection part. The mechanical part includes a base plate 1 and a three-dimensional mobile support arranged on the base plate 1. The central part of the base plate 1 is provided with a base plate 1 that can be taken out. Around the base plate 1, several A fixator 3, a spine locator and a clip are installed at the end of the base plate 1, the spine locator and the clip can effectively fix the balance position of the animal spine, so that the animal's spine is located on the center line of the base plate, and the three-dimensional mobile bracket is installed There are sensors 6 and percussion pins 5. The base plate 1 is provided with a fixture moving track 4, which enables the fixture 3 to move or position along the track 4 by turning the knob...

The invention discloses a digital spinal cord injured animal model preparation instrument, which comprises a mechanical part and an electronic detection part and is characterized in that: A. the mechanical part comprises a bottom board and a three-dimensional moving bracket arranged on the bottom board, the middle part of the bottom board is provided with a substrate which can be taken out, the periphery of the substrate is provided with a plurality of fixing apparatuses, the end part of the bottom board is provided with a spinal cord positioner and clamps, the spinal cord positioner and the clamps can effectively fix the balancing position of an animal spinal cord and ensure that a spine of an animal is positioned in the central line of the substrate, and the three-dimensional moving bracket is provided with a sensor and a striking needle; and B. the electronic detection part comprises a striking needle precise displacement conversion module, a spinal cord discharge high speed conversion acquisition module and a data processing module. The instrument has the advantages that the instrument can accurately record all the movement parameters of animal spinal cord injury striking needles and parameters from the beginning to the end of the striking, and provides more accurate and comprehensive data for research and analysis of the animal spinal cord injury.
Description
technical field [0001] The invention relates to a data acquisition device, in particular to a digital spinal cord injury animal model preparation instrument. Background technique [0002] At present, animal models of spinal cord injury usually include spinal cord impact injury model, spinal cord compression injury model, spinal cord ischemia and reperfusion injury model, cutting and suction spinal cord injury model, static pressure spinal cord injury model, photochemically induced spinal cord injury model, Tractional spinal cord injury model. However, an ideal spinal cord injury model should meet the following three conditions: (1) Clinical similarity: that is, the spinal cord injury model produced is similar to the clinical situation, as close as possible to the human condition. Theoretically speaking, the so-called "closed spinal cord injury" can simulate the injury of the spinal cord under the action of external force and the subsequent pathological changes after the spi...
