[0033] Preferably, the rat fixing frame 7 is height-adjustable.

[0034] Specifically, in one embodiment, an auxiliary device suitable for electroacupuncture treatment and evaluation of rats with spinal cord injury is provided. The rat is fixed by a rat fixation frame 7 while exposing the rat spine for spinal electroacupuncture treatment. The rat fixation frame 7 adjusts the length of the elastic fixing belt 5 through the internal fixing connection 2 to firmly and elastically fix the rat while avoiding secondary injury to the rat. The rat fixation frame is connected to the external fixation frame through the external fixation frame slide rod, panel 8 and fixing member 6, and the height of the rat fixation frame is adjusted at the same time. The rat is suspended in the air by pulling out the sliding support plate 4 to perform bladder massage on the rat with spinal cord injury without changing the body position, and observe the movement of the hind limbs. External fixation connection 1: connect the rat fixation frame and the external fixation plate by bolts. Among them, the internal fixing connection member 2: adjust the length of the elastic fixing belt of the rat fixation frame through convenient connection structures such as buttons and fixing belts; the external fixation frame slide rod: used to support the sliding support plate. The sliding support plate 4: can be slidably disassembled. After being pulled out, the rat's limbs lose support and are in a suspended or semi-supported state. After being inserted, the rat is supported. Elastic fixing belt 5: It is elastic. By adjusting the connection part with the internal fixation, the length is adjusted, and the fixing elasticity is further adjusted. The trunk of the rat with spinal cord injury is elastically fixed to reduce the risk of accidental injury and detachment caused by fixation. Sliding rod fixing part 6: On the sliding rod of the external fixator, on both sides of the panel, it is used to fix the position of the external fixator panel on the sliding rod of the external fixator. Rat fixator 7: The rat fixator is composed of a door frame-like bottom plate and three panels. The door frame-like bottom plate is used to hold up the rat. The middle part in contact with the rat spine is empty, which is used to expose the rat spine for treatment operations such as electroacupuncture. The panels on both sides are connected to the external fixation panel, and the front panel is used to block the rat's field of vision and reduce the rat to prevent the rat from turning back and biting. External fixator panel 8: The external fixator panel is connected to the rat fixator and can slide on the external fixation sliding rod. The fixing position is adjusted by the sliding rod fixing part.

[0035] The present invention supports and adjusts the height position of the rat fixing frame 7 through external fixing connection 1, external fixing frame slide rod 3, external fixing frame panel 8, external fixing frame slide rod fixture 6, etc., and adjusts the support of the rat's limbs by sliding the sliding support plate 4 in and out, thereby solving the problem that the rat's hind limb function exercise and function evaluation can be performed in both the supported state and the unsupported state in the rat with spinal cord injury. The present invention can fix the rat through the rat fixing frame 7 while exposing the rat's spinal region to facilitate electroacupuncture and other treatments, and can effectively reduce the risk of the electric needle falling off or the line being interrupted due to the movement of the rat, biting the wire, etc. during the electroacupuncture process. The present invention elastically fixes the rat through an elastic fixing belt 5, and greatly increases the elasticity and fixing operability by adjusting the length of the elastic fixing belt 5 through the internal fixing connection 2. The elastic fixation retains the activity ability of the rat's limbs. Through height adjustment, it is convenient to perform bladder massage and other operations on the rat with spinal cord injury, and reduce the risk of secondary spinal cord injury during bladder massage and intraperitoneal injection.
