Description
Technical field
The utility model is related between medical experiment auxiliary tool field more particularly to a kind of laser positioning animal spinal cord injury
Connect beating device.
Background technology
Allens invention weights in 1911 have fallen since method construction SCI models, and domestic and international many scholars are to this percussion device
It is manufactured and has been improved, at present the commonly Model III of the NYU beating devices and W.M.Keck of New York University in domestic literature
Beating device, there is two-hit in the former, the latter's price is extremely expensive, and the two manufacture model to human body spinal cord by
Hindering mechanism still has deficiency.Domestic many laboratories and researcher simplify in its principle, improve, and propose and manufactured crowd
More equipments, but there is poor accuracy mostly, be difficult to eliminate animal fine motion and the influence of canalis spinalis sclerotin, narrow application range in these equipment
The shortcomings of.
The prior art is all made of the mode that striker directly hits spinal cord, is found in actual experiment operation, with animal
Respiratory movement, backbone and spinal cord have slight displacement, this can cause striker impact position that deviation occurs, or even strike spinal cord
On the vertebral plate that side is not cut off, the impact force for acting on spinal cord is caused to be greatly lowered, influences the stability of modeling.Striker simultaneously
Spinal cord is directly hit, has the possibility for causing spinal cord endorchis to rupture, spinal cord overflows after endorchis rupture, influences to spinal cord form
Observation also influences the degree of spinal cord injury, therefore test repeatability is poor.On the other hand, human body spinal cord injury is mostly led by indirect violence
It causes, i.e., external violence is hit to human body, is transmitted to backbone sclerotin through soft tissues such as muscle, spine fracture or interverbebral disc then occurs
Damage, subsequent violence, which continues inwardly to transmit, leads to spinal cord injury, therefore the loading process of spinal cord injury is indirect loading process, existing
Some devices are direct violence strike, this is not inconsistent with personal injury's mechanism.
The prior art has a word laser positioning simultaneously, but can only navigate to target spinal cord, cannot position striker distance
The height of target spinal cord encounters the experiment for needing precise positioning height, it is necessary to especially measures, it is very inconvenient.
