Embodiment 1

[0085] Now illustrate the using method of the device of the present invention in conjunction with the accompanying drawings:

[0086] 1. Anesthetize the animal, place the animal prone on the center of the 1-experimental platform, and be perpendicular to the 9-X moving guide rail

[0087] 2. Laminectomy from the rear to expose the spinal cord

[0088] 3. Place the 17-impact hook on the ventral side (front) of the spinal cord

[0089] 4. Adjust the 9-X direction moving guide rail and the 13-Y direction moving guide rail, put the lower end of the 16-impactor moving piston close to the 17-impact hook, so that the lower end of the card slot is connected with the 17-impact hook

[0090] 5. Loosen the distance-measuring bolt, slowly drop the 18-fixed pressing piece to make it naturally attached to the surface of the spinal cord, and then tighten the bolt. At this time, the sagittal direction of the spinal cord can be read from the scale corresponding to the upper end of the 18-fixed...

Abstract

The invention relates to an impacting device for spinal-cord ventral injury for medical experiment. The impacting device consists of a supporting device, a monitoring device, a connecting-moving device, a power device and an impacting device, wherein the devices have the following connection modes that: the connecting-moving device is arranged above one side of the supporting device; the monitoring device can be loaded outside the supporting device; the connecting-moving device is in a cross shape; the left side of a transverse line of the connecting-moving device is provided with the power device; and the impacting device is arranged below the power device.

Description

Technical field: [0001] The invention relates to a spinal cord impingement device for medical experiments, in particular to an impactor for impacting the ventral side of the spinal cord of experimental animals and monitoring the impact intensity and deformation. Background technique: [0002] The most basic condition for studying spinal cord injury is to establish a quantitative and highly reproducible animal model that can truly simulate the actual injury situation. [0003] Someone has designed a WD device, combined with software that can adjust the degree of spinal cord compression and vertebral body displacement, can timely feedback the biomechanical information of the impact. Using this device, a highly repeatable spinal cord injury model can be established. A1-len used a weight drop-ping (WD) to hit the dorsal side of the spinal cord in 1911, and for the first time reproduced the spinal cord injury model in animals. Created a precedent for standardized experimental re...
