Description

Technical Field

[0001] The utility model belongs to the technical field of medical experiments, in particular to a leg fixer for rabbits used in experiments. Background Art

[0002] With the rapid development of medicine, mankind has made significant progress in overcoming various medical problems; however, even in such an advanced medical environment, some complex and difficult challenges still plague doctors and researchers; especially in the field of orthopedics, bone defects caused by trauma, tumors and infections, especially the repair and functional reconstruction of large bone defects, have always been an important problem that doctors must face;

[0003] Repairing large bone defects is not an easy task. It involves multiple aspects, such as the regeneration of bone tissue, the reconstruction of bone structure, and the restoration of function. In order to conduct in-depth research and explore effective methods for repairing bone defects, scientists often need to use experimental animal models to simulate clinical conditions. Among these experimental models, rabbits have become one of the commonly used experimental animals because of their similar physiological structure to humans and their ease of breeding and management.

[0004] In the process of using rabbits for bone defect repair experiments, fixing the rabbits' limbs is a crucial step. Since the rabbits' limbs need to be subjected to various operations during the experiment, such as surgery and drug injection, if the limbs are not fixed properly, it will not only affect the accuracy and stability of the experimental operation, but may also cause unnecessary harm to the rabbits.

[0005] The traditional fixation method is to place the rabbit on a specially designed workbench and then insert the rabbit's limbs into pre-set clamps. Once the limbs are correctly placed in the clamps, the device can drive the clamps down to fix the limbs. However, the limitation of this method is that the spacing of the clamps is pre-set and fixed. This means that only rabbits whose limbs are perfectly matched to the spacing between the clamps can be effectively fixed. For rabbits that are larger or smaller in size, this fixation method may not be fully applicable, as either the limbs cannot be fully inserted into the clamps or sufficient fixation cannot be achieved even after insertion. This will reduce the scope of use of the device. Utility Model Content

[0025] A fixing mechanism is arranged inside the workbench 2, and the fixing mechanism includes a gear plate 3, which is rotatably connected to the top of the workbench 2. A slide groove 11 is opened on the surface of the gear plate 3, and a slider 4 is slidably connected inside the slide groove 11. A fixing box 5 is fixedly installed on the top of the slider 4, and a clamp 6 is slidably connected inside the fixing box 5. A support plate 7 is fixedly installed on the top of the workbench 2, and a rack 8 is fixedly installed on the bottom end of the clamp 6. Motor 1 9 is fixedly installed on the opposite side of the fixing box 5, and the output end of motor 1 9 extends to the inside of the fixing box 5 and is fixedly installed with gear 10, and a protective cover 12 is fixedly installed on the top of the inside of the clamp 6. Motor 2 13 is fixedly installed on the top of the workbench 2, and gear 2 14 is fixedly installed on the output end of motor 2 13.

[0026] The above scheme is adopted: the operator places the rabbit on the top of the workbench 2, and then places the rabbit's limbs on the top of the support plate 7, and then the limbs will be aligned with the four clamps 6, and then the motor 2 13 can be driven to rotate the gear 2 14, because the gear 2 14 is engaged with the gear plate 3, and then the gear 2 14 will drive the gear plate 3 to rotate, when the gear plate 3 rotates, the slide 11 will rotate accordingly, because the slide 11 is inclined, and then when the slide 11 rotates, the slider 4 will move inside the slide 11, and the slider 4 will move toward the direction of the rabbit's limbs, and then the clamp 6 will be sleeved on the surface of the limbs, and then the motor 1 9 can be driven to rotate the gear 10, because the gear 10 is engaged with the rack 8, and then the gear 10 will drive the rack 8 to descend during the rotation, and then the rack 8 will drive the clamp 6 to descend, and then the bottom end of the protective cover 12 will contact with the rabbit's limbs, thereby fixing the rabbit's limbs.

[0027] like Figure 2 As shown, a slot 17 is provided at the top of the front side of the workbench 2, and a plug plate 18 is slidably connected inside the slot 17. A universal wheel 19 is fixedly installed at the bottom end of the base 1. There are four universal wheels 19, which are evenly distributed at the bottom end of the base 1.

[0028] The above scheme is adopted: through the design of the slot 17 and the plug plate 18, the plug plate 18 can be pulled out from the inside of the slot 17, which makes it convenient for the operator to observe the internal structure of the workbench 2, thereby facilitating the operator to perform maintenance and installation; through the design of the universal wheel 19, the operator can push the device to make the universal wheel 19 rotate, and during the rotation of the universal wheel 19, it will drive the entire device to move.

[0029] like Figure 1 and Figure 5 As shown, a limiting groove 15 is provided on one side inside the fixed box 5, and a limiting block 16 is slidably connected inside the limiting groove 15.

The output shaft of the electric push rod 21 passes through the mounting plate 20 downward and is fixedly installed with a friction plate 22.

[0030] The above scheme is adopted: through the design of the limit groove 15 and the limit block 16, when the rack 8 moves, the limit block 16 will move inside the limit groove 15, and then the rack 8 can be limited to prevent the rack 8 from moving out of the fixed box 5, thereby ensuring the normal movement of the clamp 6; through the design of the mounting plate 20, the electric push rod 21 and the friction plate 22, before the device works, the electric push rod 21 can be driven, and then the output shaft of the electric push rod 21 will push the friction plate 22 down, and then the bottom end of the friction plate 22 will contact the ground, thereby ensuring the stability of the device operation.

[0031] like Figure 4 and Figure 5 As shown, a baffle is provided at the bottom end of the slider 4, and the top end of the baffle contacts the bottom end of the gear plate 3. The protective sleeve 12 is U-shaped and made of rubber.

[0032] The above scheme is adopted: through the design of the slider 4, when the slider 4 moves, the top end of the baffle contacts the bottom end of the gear plate 3, and the fixing box 5 can be limited by the cooperation of the fixing box 5 and the baffle; through the design of the protective cover 12, when the bottom end of the protective cover 12 contacts the limbs of the rabbit, since the protective cover 12 is made of rubber material and is relatively soft, the limbs of the rabbit can be protected when the limbs of the rabbit are fixed.

[0033] The working principle and use process of this utility model:

[0034] First, the operator places the rabbit on the top of the workbench 2, and can place the limbs on the top of the support plate 7, then the motor 2 13 can be driven to rotate the gear 2 14, the gear 2 14 will drive the gear plate 3 and the slide 11 to rotate, the slider 4 will move inside the slide 11, and then the slider 4 will move in the direction of the rabbit's limbs, and then the slider 4 will drive the fixing box 5 and the clamp 6 to move, and the clamp 6 will be put on the surface of the limbs, then the motor 1 9 can be driven to rotate the gear 10, the gear 10 will drive the rack 8 and the clamp 6 to descend, the clamp 6 will drive the protective cover 12 to descend, and then the surface of the protective cover 12 will contact with the rabbit's limbs, thereby fixing the limbs. After the fixation is completed, the operator can conduct experiments on the rabbit.
