摘要：
Provided is a driving device used for magnetic resonance elastography of an animal and an extra-corporeal sample, the driving device comprising a base (10), and the base (10) being provided with a piezoelectric driver and an animal/sample mounting mechanism driven by the piezoelectric driver, wherein the piezoelectric driver comprises a hollow oval beam (21) and a piezoelectric ceramic sheet (22) arranged along a long axis of the oval beam (21), two ends of the piezoelectric ceramic sheet (22) are respectively connected to two ends of the oval beam (21) that correspond to the long axis thereof, and two ends of the oval beam (21) that correspond to a short axis are power output ends (23) and the mounting mechanism comprises a driver connecting member (31) connected to one of the power output ends (23), a driving rod (32) connected to the driver connecting member (31), an anaesthesia ferrule (33) sheathed at an end portion of the driving rod (32), and two adjusting brackets (34) arranged on the base (10), respectively located on two sides of the driving rod (32), and used for adjusting a mounting position of the animal/sample, wherein end portions of the two adjusting brackets (34) extend beyond an end portion of the anaesthesia ferrule (33), the end portions of the adjusting brackets (34) extending beyond the anaesthesia ferrule (33) are animal head fixing ends, and the fixing ends are provided with several fixing holes (35). The driving device is simple in structure and has a relatively high power transmission efficiency.La présente invention concerne un dispositif dentraînement utilisé pour lélastographie par résonance magnétique dun animal et dun échantillon extracorporel, le dispositif dentraînement comprenant une base (10), et la base (10) étant pourvue dun dispositif dentraînement piézoélectrique et dun mécanisme de montage danimal/déchantillon entraîné par le dispositif dentraînement piézoélectrique, le dispositif dentraînement piézoélectrique comprenant un ar
