[0022] The present application will now be described in detail. While specific embodiments of the present application are shown, it should be understood that the present application can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0023] It should be noted that certain terms are used in the specification and claims to refer to specific components. Those skilled in the art will understand that different terms may be used to refer to the same component. This specification and claims do not distinguish components based on differences in terminology, but rather on differences in function. The terms "comprising" or "including" used throughout the specification and claims are open-ended and should be interpreted as "comprising but not limited to." The following descriptions in the specification are preferred embodiments for carrying out this application; however, these descriptions are for the purpose of understanding the general principles of the specification and are not intended to limit the scope of this application. The scope of protection of this application shall be determined by the appended claims.

[0024] refer to Figure 1 This application provides a device for securing small and medium-sized animals; including a cage 1 placed on the ground, a lifting platform 2 provided on the lower end surface of the cage 1, a lifting foot provided on one side of the lifting platform 2, and the lifting platform 2 being hinged to the cage 1 on the side away from the lifting foot.

[0025] The fixed cage 1 is a cage structure formed by interconnected strips. There are gaps between the strips. Once a small or medium-sized animal enters the fixed cage 1, it is difficult for the animal to escape. At the same time, the surgeon can observe the animal in the fixed cage 1 through the gaps, and furthermore, the surgeon can also enter the fixed cage 1 through the gaps to perform surgery on the animal.

[0026] refer to Figure 1 When performing surgery on small and medium-sized animals, the animals are placed in a fixed cage 1 to restrict their movement and reduce the harm to the surgeon caused by the animals struggling during the operation.

[0027] The lifting platform 2 is located on the lower end of the fixed cage 1. When a small or medium-sized animal is secured in the fixed cage 1, the animal stands on the lifting platform 2, and the platform can be raised or lowered using the lifting feet. One side of the lifting platform 2 is hinged to the fixed cage 1. Therefore, the side of the lifting platform 2 away from the hinge axis will rise or fall as the lifting feet move. Simultaneously, the animal on the lifting platform 2 will also rise or fall as the platform 2 moves. This allows the surgeon to more easily perform surgery on the animal from a suitable position after the lifting platform 2 has raised it.

[0028] Using a lifting platform 2 located within the fixed cage 1, the position of the animal within the cage 1 can be adjusted, allowing the animal to be moved to a suitable height according to the surgeon's needs. For example, if the head needs to be raised to a certain position, the animal's forelimbs can be placed in the lifting foot positions on the lifting platform 2, thereby raising the animal's forelimbs and head. The lifting platform 2 allows the surgeon to move the area to be operated on to a suitable surgical height. On one hand, this improves the surgeon's comfort during animal surgery, thus increasing surgical efficiency. On the other hand, the lifting platform 2, by raising the animal's position, distributes force more evenly compared to manual lifting or using ropes, improving the animal's comfort during movement; this reduces the likelihood of the animal struggling violently during surgery, and consequently, the possibility of the animal causing harm to the surgeon.

[0029] In one specific embodiment, the lifting foot is a hydraulic device 3.

[0030] In another specific embodiment, the lifting foot is a threaded screw device.

[0031] In another specific embodiment, the lifting foot is a guide rail device.

[0032] Preferably, the lifting foot is a hydraulic device 3.

[0033] refer to Figure 1 The upper end of the hydraulic device 3 is fixedly connected to the lifting platform 2, and the lower end of the hydraulic device 3 is fixed to the ground or the fixed cage 1.

[0034] When the upper end of the hydraulic device 3 is fixedly connected to the lifting platform 2, since the lifting platform 2 rotates and rises, the angle between the hydraulic device 3 and the lifting platform 2 becomes an acute angle after the lifting platform 2 rises. Therefore, the fixed connection between the upper end of the hydraulic device 3 and the lifting platform 2 has a certain degree of elasticity, allowing the lifting platform 2 and the hydraulic device 3 to undergo a certain amount of deformation. At the same time, the hydraulic device 3 can also push the lifting platform 2 to raise and lower it.

[0035] In one specific embodiment, the lower end of the hydraulic device 3 is fixed to the ground.

[0036] In another specific embodiment, the lower end of the hydraulic device 3 is fixed to the fixed cage 1, and the hydraulic device 3 is fixedly connected to the fixed cage 1.

[0037] In another specific embodiment, the lower end of the hydraulic device 3 is hinged to the fixed cage 1.

[0038] refer to Figure 1Since the lifting platform 2 rotates and rises when the hydraulic device 3 drives the lifting platform 2 to rise or fall, the lifting platform 2 and the hydraulic device 3 have some displacement in both the height and horizontal directions. Therefore, when the hydraulic device 3 is fixed on the fixed cage 1, the fixed connection between the fixed cage 1 and the hydraulic device 3 has a certain degree of elasticity, which enables the hydraulic device 3 to push the lifting platform 2 to rise or fall.

[0039] When the hydraulic device 3 is hinged to the fixed cage 1, the hydraulic device 3 can rotate simultaneously with the lifting platform 2, thereby enabling the lifting platform 2 to rise smoothly.

[0040] When the hydraulic device 3 is connected to the fixed cage 1, the fixed cage 1 can be used in more locations, freeing it from the limitation of being placed on the ground. This improves the usability of the fixed cage 1.

[0041] refer to Figure 1 The fixed cage 1 has an opening on one side. Preferably, an opening frame is provided at the opening, and the opening frame is hinged to the fixed cage 1.

[0042] The opening is used to allow animals to enter the cage 1. The opening is located on the side of the cage 1, so that when an animal enters the cage 1, it enters from the side.

[0043] refer to Figure 1 The opening is located on the side of the fixed cage 1, so that the top of the fixed cage 1 is fixedly connected to the side of the fixed cage 1, thereby increasing the connection strength between the top of the fixed cage 1 and the fixed cage 1, and reducing the possibility of the top of the fixed cage 1 falling off.

[0044] On the other hand, by placing the opening on the side, when it is necessary to place the animal into the fixed cage 1, the animal can simply be moved or pushed into the fixed cage 1 through the opening. Compared to placing the opening at the top, there is no need to lift the animal, reducing the possibility of the animal moving due to deviation or other reasons during movement. This facilitates the movement of the animal before and after surgery.

[0045] An opening frame is used to seal the opening and prevent animals from escaping through it.

[0046] A collar 4 is provided on the side of the fixed cage 1 away from the opening, and the collar 4 is located near the middle.

[0047] refer to Figure 1 The collar 4 is used to secure the animal's neck, thus fixing the animal's head to the cage 1. When the animal is moved into the cage 1, its head is transported inwards, so that the animal's head and neck can be positioned precisely at the collar 4.

[0048] In order to make full use of the space inside the fixed cage 1, and at the same time minimize the movement space of the animal in the fixed cage 1, the animal's head is fixed by the collar 4 after the animal enters the fixed cage 1.

[0049] The collar 4 is positioned on the side of the cage 1 away from the mouth, near the center. This allows the collar 4 to secure animals of varying sizes. Since the animal's neck and head have a certain range of motion, smaller, shorter animals can be secured by raising their heads before using the collar 4. Conversely, larger or taller animals can be secured by lowering their heads. This allows the cage 1 to accommodate animals of a wider range, increasing its applicability and frequency of use.

[0050] A first connecting strap 5 is provided on the outer circumference of the collar 4, and the two ends of the first connecting strap 5 are respectively fixed to the collar 4 and the fixing cage 1.

[0051] The first connecting strap 5 has a certain degree of elasticity and is relatively strong. The collar 4 is a circular structure with an adjustable diameter, which can be firmly fitted onto the animal's neck, thereby fixing the animal's head.

[0052] During surgery, animals inevitably struggle. A fixed head can increase the risk of injury to the animal from the collar 4 during struggles. Therefore, a first connecting strap 5 is used as a buffer. When the animal struggles, the first connecting strap 5 can undergo a certain degree of elastic deformation to reduce the force exerted by the collar 4 on the animal, thereby reducing the risk of injury from the collar 4.

[0053] refer to Figure 1 The first connecting strap 5 is evenly arranged in four directions around the collar 4; and the four first connecting straps 5 are respectively fixed at the four corners of the fixed cage 1.

[0054] Since the collar 4 is fixed to the animal's neck, the force exerted on the neck and head is considerable when the animal struggles. Furthermore, the animal's head moves significantly and in multiple directions. Therefore, the first connecting strap 5 is attached to a corner of the cage 1, thereby increasing the connection strength between the first connecting strap 5 and the collar 4. Additionally, the first connecting strap 5 is attached diagonally to the cage 1, further increasing the load-bearing capacity of the cage 1. This enhances the ability of the cage 1 and the first connecting strap 5 to withstand the forces exerted by the animal's struggles.

[0055] A belly ring 6 is provided inside the fixed cage 1, and the belly ring 6 is located near the center of the fixed cage 1.

[0056] The abdominal collar 6 is used to secure the animal's abdomen. When the animal enters the cage 1, its abdomen is located near the middle of the cage 1. Therefore, the abdominal collar 6 is used to secure the animal's abdomen, thereby reducing the animal's movement space in the cage 1 and reducing the possibility of the animal struggling.

[0057] refer to Figure 1 A second connecting strap 7 is provided on the abdominal ring 6, and the two ends of the second connecting strap 7 are respectively fixed on the abdominal ring 6 and the fixing cage 1.

[0058] The abdominal ring 6 is fixed to the cage 1 using the second connecting strap 7. The second connecting strap 7 has a certain degree of elasticity, so when the animal struggles in the cage 1, the second connecting strap 7 will undergo a certain elastic deformation, thereby reducing the force of the abdominal ring 6 on the animal's abdomen when fixing the animal.

[0059] The second connecting band 7 is provided in two or four.

[0060] In one specific embodiment; when two second connecting straps 7 are provided, both second connecting straps 7 are fixed above the belly ring 6, and the upper ends of the second connecting straps 7 are respectively fixed on the opposite side edges of the fixing cage 1.

[0061] After securing the animal's abdomen with the abdominal collar 6, the animal will tend to sink under gravity during surgery. The abdominal collar 6 will then exert an upward force to hold the animal in place, reducing movement during the procedure. Therefore, two second connecting straps 7 are attached to the upper end of the cage 1 to suspend and secure the animal during surgery.

[0062] Furthermore, the inclusion of two second connecting straps 7 allows for greater mobility in the abdominal ring 6, enabling it to move more freely and further reducing its restriction on the animal's abdomen. This also facilitates the surgeon's restraint of the animal after it has been placed in the restraint cage 1. It allows the surgeon to move and wrap the abdominal ring 6 around the animal's abdomen more easily and quickly, reducing the restraint effect and improving the animal's comfort during surgery. This structure is more suitable for restraining more docile animals.

[0063] refer to Figure 1 In another specific embodiment, when four second connecting straps 7 are provided, the four second connecting straps 7 are evenly arranged on the outer periphery of the belly ring 6, and the ends of the second connecting straps 7 away from the belly ring 6 are respectively fixed on the four edges of the fixing cage 1.

[0064] Four second connecting straps 7 are installed, thus completely securing the abdominal ring 6 to the center of the cage 1. This provides comprehensive fixation of the animal's abdomen. Furthermore, the four second connecting straps 7, after securing the abdominal ring 6, can also accommodate the animal's struggles in specific situations, such as a cat arching its back in fright. Therefore, this structure provides more stable fixation for the animal and reduces its room for struggle. This structure is more suitable for more aggressive animals.

[0065] A foot ring 8 is provided on the fixed cage 1. The foot ring 8 is used to fix the legs and feet of small and medium-sized animals. The foot ring 8 is located in the fixed cage 1 near the middle in the vertical direction.

[0066] During animal surgery, leg bands 8 are used to secure the animal's hind legs. Furthermore, during surgery, the animal's hind legs need to be raised to facilitate observation and operation by the surgeon. Therefore, when securing the animal, its hind legs need to be raised and fixed at the same level as its abdomen. After the animal is secured, its hind legs are positioned in a flat, lying position. The two hind legs are then separately secured to opposite sides of the cage 1; the animal's exterior is spread out for observation and surgery by the surgeon.

[0067] In summary, this application provides a restraint device for small to medium-sized animals. When performing surgery on an animal using a restraint cage 1, the animal's head is placed into the cage 1 through the opening. A collar 4 is used to secure the animal's neck to reduce head struggle. Then, a belly collar 6 is used to secure the animal's abdomen. Finally, two leg rings 8 are used to secure the animal's two hind limbs to both sides of the cage 1. This completes the animal restraint. When restraining or observing the animal, the animal can be raised using a lifting platform 2, facilitating observation by the surgeon. Raising the animal also makes it easier to secure the hind limbs to the leg rings 8. Finally, an opening frame is installed on the opening to seal it.

[0068] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
