慢性脊髓压迫是临床常见病,其病理机制仍不清楚,关键在于缺乏具有临床相似性的动物模型。以往建立的慢性压迫模型,如常见的螺钉法、球囊法、双套管法等[1~3]其实是多次急性压迫的集合。为解决这一问题,我们研发了一种新型的微型智能化且可调节的脊髓压迫器,并建立了动物模型,通过行为学、电生理学、病理生理学等方面对该模型进行了评价。实验材料8只新西兰兔(平均体重为3.1kg,由上海 Chronic spinal cord compression is a common clinical disease, the pathological mechanism is still not clear, the key is the lack of clinical analogy animal models. Previously established chronic compression models, such as the common screw method, balloon method, double-tube method [1-3] is actually a collection of multiple acute oppression. In order to solve this problem, we developed a new type of miniature intelligent and adjustable spinal cord compressors and established an animal model to evaluate the model through behavioral, electrophysiology and pathophysiology.
