Description

Technical Field

[0001] This utility model relates to the field of spinal orthotics, and more particularly to a spinal orthotics for rats. Background Technology

[0002] The incidence of spinal cord injury is gradually increasing due to various reasons. How to effectively treat spinal cord injury and improve the quality of life of patients is a hot topic and key issue that needs to be addressed in current medical research. Rats have become the main experimental animals for spinal cord injury because they are highly similar to human physiology and pathology, and are inexpensive and easy to handle. However, rats are prone to various complications after spinal cord transection surgery, which reduces the stability and success rate of spinal cord injury experimental animal models. Postoperative care using rat spinal orthoses can effectively fix and stabilize the rat's spine, reducing spinal displacement or injury caused by activity or other factors after surgery, thereby reducing the occurrence of complications and improving the stability and success rate of spinal cord injury experimental animal models.

[0003] Most existing rat spinal orthotics have an integrated binding strap that wraps around the rat's chest and abdomen during use to position and correct the rat's spine in order to improve the survival rate of rats after surgery. However, the size of rats in biological models varies greatly, and it is difficult to judge the pressure of the binding strap on the rat's body, which can easily lead to self-harm by the rat, resulting in a decrease in the effectiveness and applicability of rat spinal orthotics.

[0004] Therefore, in view of the problem that the existing rat spinal orthotics are difficult to adapt to the size and physical condition of rats in biological models, which leads to a decrease in the effectiveness and applicability of the rat spinal orthotics, a new rat spinal orthotics can be designed.

A useful... The spinal correction frame 22 for positioning the rat's spine adapts to the rat's body shape and is positioned by the abdominal plate body 1 and the thoracic plate body 9. A movable platform 14 is installed by a fixing strap 12, so that the mounting platform 17 can be installed and rotated by the support rod 15 and the connecting block 16 to move the rotating frame 18 and the slider 19. The spinal correction frame 22 is raised and lowered by the threaded rod 20 and the rotating joint 21 to position the rat's spine for correction. An elastic rib plate 2 is installed on the inner side of the abdominal plate body 1. Mounting rods 3 are fixed to the front and rear ends of the abdominal plate body 1. A mounting frame 4 is fixed to the lower end of the abdominal plate body 1. The elastic rib plate 2 supports the rat's abdomen to balance the pressure of the spinal correction frame 22, reduce the stimulation to the rat, stabilize the rat's state, prevent the rat from being injured, and facilitate the observation of the state of the spinal surgery experiment. The mounting rods 3, together with the straps, are used to restrain different positions on the rat's body.

[0025] Please see Figures 2-6In this embodiment, an elastic plate 5 is installed on the inner side of the mounting frame 4. A buckle 6 is fixedly connected to one end of the elastic plate 5, and a first connecting plate 7 is slidably connected to one end of the mounting frame 4. The elastic plate 5 and the buckle 6 facilitate the installation and positioning of the movable structure. A first slot 8 is provided at the lower end of the first connecting plate 7. The first connecting plate 7 and the breast plate body 9 are rotatably connected through a damping shaft. The first slot 8, in conjunction with the elastic plate 5 and the buckle 6, positions the first connecting plate 7 and the breast plate body 9. A connecting rod 10 is installed on both ends of the breast plate body 9. The connecting rod 10 is slidably connected to the abdominal plate body 1. An opening 11 is provided at the lower end of the breast plate body 9. The connecting rod 10 connects the abdominal plate body 1 and the breast plate body 9, improving stability. The opening 11 facilitates the movement of the rat's limbs. A support and limiting frame 13 is provided at one end of the fixing strap 12. The support and limiting frame 13 is rotatably connected to the chest plate body 9. A second connecting plate 23 is slidably connected to the other end of the mounting frame 4. The support and limiting frame 13, together with the chest plate body 9, supports and positions the fixing strap 12 to restrain the rat's chest and head and neck in conjunction with the moving platform 14. A second slot 24 is provided at the lower end of the second connecting plate 23. A tail ring 25 is rotatably connected to one end of the second connecting plate 23 through a damping pivot. The tail ring 25 is slidably connected to the rotating frame 18. The second connecting plate 23 is positioned by the second slot 24 in conjunction with the elastic plate 5 and the buckle 6, and the tail ring 25 is positioned in conjunction with the rotating frame 18 to restrain the rat's tail.

[0026] During installation, firstly, the first connecting plate 7 and the chest plate body 9 are positioned by the first slot 8 in conjunction with the elastic plate 5 and the buckle 6, and the abdominal plate body 1 and the chest plate body 9 are connected by the docking rod 10 to improve stability. Next, the support limiting frame 13 is used in conjunction with the chest plate body 9 to support and position the fixing strap 12, so as to cooperate with the moving platform 14 to restrain the rat's chest and head and neck. Then, the mounting rod 3 is used in conjunction with the straps to restrain different positions on the rat's body, and the tail ring 25 is placed between the middle of the rat's tail and the buttocks. Finally, the second connecting plate 23 is positioned by the second slot 24 in conjunction with the elastic plate 5 and the buckle 6, and the tail ring 25 is positioned in conjunction with the rotating frame 18 to restrain the rat's tail.

[0027] In use, firstly, the rat's abdomen is supported by the elastic rib plate 2 to balance the pressure of the spinal correction frame 22, reduce the stimulation to the rat, stabilize the rat's state, and prevent injury, thus facilitating the observation of the spinal surgery test. Next, the movable platform 14 is installed by the fixing strap 12, and the open opening 11 facilitates the rat's limb movement, allowing the abdominal plate body 1 and thoracic plate body 9 to adapt to the rat's body shape and be positioned. Then, the mounting platform 17 is installed and rotated by the support rod 15 and connecting block 16 to move the rotating frame 18 and slider 19, thereby adapting to different rat body shapes and gradually adjusting the position of the spinal correction frame 22 in stages to adjust the correction effect. Finally, the spinal correction frame 22 is raised and lowered by the threaded rod 20 and rotating joint 21 to position the rat's spine for correction.

[0028] Through the above steps, the abdominal plate body 1 and the thoracic plate body 9 are adapted to the rat's body shape and positioned. The movable platform 14 is installed through the fixing strap 12, so that the mounting platform 17 can be installed and rotated through the support rod 15 and the connecting block 16 to move the rotating frame 18 and the slider 19. The spinal correction frame 22 is raised and lowered through the threaded rod 20 and the rotating joint 21 to position the rat's spine and thus perform correction. This solves the problem that existing rat spinal orthotics are difficult to adapt to the size and physical condition of rats in biological models, which leads to a decrease in the effectiveness and applicability of rat spinal orthotics.
