Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figure 1-4 The image shows a device for creating a rat intervertebral disc degeneration model.

[0036] Example 1

[0037] The device includes a first barrel 1, a second barrel 2, a connecting cylinder 3, a restraint collar 4, and a locking assembly 5. The second barrel 2 is located on top of the first barrel 1, and the connecting cylinder 3 is located between the first barrel 1 and the second barrel 2. The first barrel 1, the second barrel 2, and the connecting cylinder 3 can be assembled to form a rat modeling operation barrel. The outer wall of the connecting cylinder 3 has an operation opening. The restraint collar 4 is fixedly sleeved on the end of the outer wall of the connecting cylinder 3. The opposite ends of the outer walls of the first barrel 1 and the second barrel 2 are respectively slidably sleeved with the restraint collar 4. The locking assembly 5 is located on the side of the first barrel 1 and the second barrel 2. The locking assembly 5 is used to lock the first barrel 1 and the second barrel 2. Under the action of the locking assembly 5 and the restraint collar 4, the first barrel 1, the second barrel 2, and the connecting cylinder 3 can be spliced ​​into a whole, and the connecting cylinder 3 can rotate relative to the first barrel 1 and the second barrel 2, thereby changing the position of the operation opening corresponding to the rat.

[0038] Specifically, it also includes an end cap 8, a clamp 9, and a sealing plate 6. The end cap 8 is attached to the top of the second barrel 2. The clamp 9 is installed inside the first barrel 1 and the second barrel 2 respectively. The clamp 9 is used to clamp and restrain the rat. The clamp 9 consists of a clamping plate, an electric telescopic rod, and a pressure sensor. The pressure sensor is located on the side of the clamping plate facing the rat. The pressure sensor and the electric telescopic rod are connected to an external controller. The controller controls the electric telescopic rod to drive the clamping plate to clamp the rat. The pressure sensor can detect the clamping force between the clamping plate and the rat. After the clamping force of the clamping plate on the rat reaches a certain value, the controller controls the electric telescopic rod to drive the clamping plate to move towards the rat. This is existing technology and will not be described in detail here. The sealing plate 6 is rotatably connected to the outside of the connecting cylinder 3. A locking bolt 7 is provided on one side of the sealing plate 6 and is threadedly connected to the connecting cylinder 3. Under the action of the locking bolt 7, the sealing plate 6 can seal and block the operating port on the connecting cylinder 3.

[0039] Example 2

[0040] Based on Embodiment 1, the locking assembly 5 includes a connecting collar 51, a first snap-fit ​​member 52, and a second snap-fit ​​member 53. The connecting collar 51 is fixedly connected to one end of the outer wall of the first barrel 1 and the second barrel 2 respectively, facing away from each other. The first snap-fit ​​member 52 and the second snap-fit ​​member 53 are respectively snapped into one side of the connecting collar 51. The locking assembly 5 also includes a fixing plate 54 and a locking block 55. The fixing plate 54 is fixedly connected to the outside of the connecting collar 51, and the side of the locking block 55 is fixedly connected to the fixing plate 54. The first snap-fit ​​member 52 and the second snap-fit ​​member 53 are both provided with a slot. The outer wall of the locking block 55 is slidably snapped into the inner cavity of the slot. Thus, the first snap-fit ​​member 52 and the second snap-fit ​​member 53 cooperate with the fixing plate 54 and the locking block 55 to lock the height of the first barrel 1 and the second barrel 2. And cooperate with the restraining collar 4 to ensure the stability of the assembly of the first barrel 1, the second barrel 2, and the connecting cylinder 3.

[0041] Furthermore, the locking assembly 5 also includes a connecting rod 56, a limiting plate 57, a limiting block 58, and a limiting spring 59. The first latching member 52 and the second latching member 53 each have a mounting groove corresponding to the connecting rod 56 at their opposite ends. The limiting plate 57 is fixedly connected to the end of the mounting groove cavity. The outer wall of the connecting rod 56 is slidably inserted into the limiting plate 57. The limiting block 58 is fixedly connected to the end of the connecting rod 56 and slidably fitted inside the mounting groove. The limiting spring 59 is slidably fitted outside the connecting rod 56 and is located between the limiting plate 57 and the limiting block 58. The limiting spring 59 can provide a relatively cohesive elastic force to the first latching member 52 and the second latching member 53 through the connecting rod 56, the limiting block 58, and the limiting plate 57, thereby ensuring that the first latching member 52 and the second latching member 53 are in a stable state and are latched and locked to the first barrel 1 and the second barrel 2.
