Description
Technical field
The present invention relates to a kind of spinal cord mechanical compression device.
Background technology
Cervical spondylosis myeloid form (CSM) is commonly encountered diseases, frequently-occurring disease in mid-aged population, the self-care ability of grievous injury patient.Because CSM natural history is long, pathomechanism is complicated, at present CSM is grasped not yet completely, especially cannot illustrate the relation between " spinal compression " and " nerve function lesion ".Animal model in the past also exists the position of compressing, degree is wayward, and only designs static compressing factor and do not design the problems such as dynamic compressing factor, thus cannot the clinical setting of meticulous imitation CSM.For the research of this non-lethality wound of making slow progress of chronic spinal cord injury, animal model just seems even more important.Good animal model not only has facilitation to the cause of disease of disease, pathological research, to the clinical new Therapeutic Method of exploration and improve clinical therapeutic efficacy and be also significant.Only under identical animal experimental model condition, spinal cord injury mechanism could be studied, observe the rear pathophysiological change of damage, find out reliable, the sensitive method that directly can judge degrees of spinal cord injury and optimize the preferred plan for the treatment of spinal cord injury.
Current Chronic Spinal Cord damage model is various, having of comparative maturity: the direct compression model of oncothlipsis model, screw, balloon tamponade model, liquid capsule compression model, expandable material compression model, toe walking Yoshimura mouse model.In experimentation, animal model species is various, respectively has its pluses and minuses.Its major defect is cannot need to produce accurate compressing according to test, and repeatability is poor by force, and operation related complication is high.
Summary of the invention
The object of this invention is to provide a kind of spinal cord mechanical compression device, to overcome currently available technology above shortcomings.
The object of the invention is to be achieved through the following technical solutions:
A kind of spinal cord mechanical compression device, comprise the compression system and body controlling system that are connected by wire, compression system is fixed on intervertebral space by fixture, described compression system comprises frame, be provided with gear motor in frame, the below of gear motor is provided with slideway, is provided with push rod in slideway, one end of push rod is provided with compressing head, and the other end of push rod is provided with spring; Described body controlling system comprises surface-mounted integrated circuit by connection and high capacity lithium ion battery, the front of surface-mounted integrated circuit is provided with single-chip microcomputer, the back side of surface-mounted integrated circuit is provided with bluetooth module, is provided with motor drive ic below bluetooth module, and the left side of bluetooth module is provided with tongue tube.
Further, described push rod is connected with being gone between by transmission between gear motor.
Further, described fixture comprises base plate and steel plate, matches with the outline of frame in the middle part of steel plate, and the two ends of steel plate are fixed on the two ends of base plate by screw.
Beneficial effect of the present invention is:
1, improve controllability: the degree of accuracy of compressing can be made to bring up to 0.1mm by the rotation controlling gear motor, substantially increase degree of accuracy and the controllability of chronic spinal compression, this animal model is worth higher.
2, favorable repeatability: can adjust under fluoroscopy and adjust initial position arbitrarily, can reduce the systematic error between each animal as far as possible, improves the repeatability of model.
3, easy to operate: the present invention adopts external telecontrol engineering, once implant in animal body, without the need to multi-time inflating or water filling, can directly by there being the mobile phone of Bluetooth function to carry out remote control.Require low to experimenter, all operations may be displayed on mobile phone.And can level of compression be intervened, and then convenient design is more complicated, closer to the experiment of pathological process.
4, reduce infect: carry out because postoperative operation is all external, need not as water pocket model percutaneous injection contrast agent, also need not retain skin cut as screw model, significantly reduce infection rate, reduce mortality of animals, reduce experimentation cost.
5, cheap: equipment can repeatedly use, can for the experiment of many group different designs simultaneously.
