It includes livestock grazing, poultry raising, and domestication of economic beasts. During the breeding process, animals sometimes get their mouths injured due to accidentally eating sundries, and it is often necessary to use an oral dilator to examine and treat the animals.

[0003] For example, the Chinese patent with the publication number CN217338969U discloses a veterinary oral dilator for livestock, which includes a lower jaw dilator plate and an upper jaw dilator plate. Fixed plates are arranged on both sides of the lower jaw dilator plate, and a lower jaw binding and fixing component is arranged between the two fixed plates; connecting plates are arranged on both sides of the upper jaw dilator plate, and an upper jaw binding and fixing component is arranged between the two connecting plates; a distance adjusting mechanism is arranged between the fixed plate and the connecting plate on the same side. The utility model is not easy to block the animal's oral cavity, which is convenient for veterinarians to clearly observe the internal situation of the animal's oral cavity from multiple angles, can conduct more detailed observations, and the device is not easy to fall off due to the animal's struggle, and has a good use effect.

[0004] However, the above device has drawbacks. For example, when supporting the animal's oral cavity, the angle of the dilating block is often relatively fixed, so that when dilating the oral cavity of animals at different angles, it is impossible to accurately adjust to a fixed angle, and veterinarians need to frequently manually adjust the best position of the dilating block, which affects the treatment effect of the animal's oral cavity.

[0005] Therefore, improvements are made in response to the above problems. Content of the Utility Model

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 4 As shown, this embodiment provides a livestock medical oral opening device, including

[0029] A frame body 1 and a pair of open support frames 2, wherein the open support frames 2 are rotatably connected to both sides of the frame body 1 through pins;

[0030] A transmission support assembly 3, the transmission support assembly 3 is arranged inside the frame 1;

[0031] The catheter correction assembly 4 is arranged outside the frame body 1;

[0032] The transmission support assembly 3 includes a first cavity 3-1 opened in the frame body 1. A second cavity 3-2 is opened in the frame body 1. The first cavity 3-1 communicates with the second cavity 3-2. A pair of driving shafts 3-3 are rotatably connected in the first cavity 3-1. Long holes 3-4 are opened on both side surfaces in the second cavity 3-2. A transmission screw 3-5 is rotatably connected in the second cavity 3-2. Transmission wheels 3-6 are arranged at the upper ends of the driving shafts 3-3. The transmission wheels 3-6 are connected by belt drive. Transmission gears 3-7 are arranged at the lower end of the driving shaft 3-3 and one end of the transmission screw 3-5 respectively. The transmission gears 3-7 are meshed with each other. A pair of long grooves 3-8 are opened at the bottom of the opening support frame 2. A moving block 3-9 is connected to the outside of the transmission screw 3-5 by thread fit. The moving block 3-9 is in sliding fit with the inner surface of the long hole 3-4. Connecting grooves 3-10 are opened on opposite end surfaces of the moving block 3-9. A connecting rod 3-11 is rotatably connected between the connecting grooves 3-10 by a pin shaft.

[0033] In this embodiment, in order to achieve the effect of adjustable angle opening of the oral cavity, the transmission support assembly 3 is designed. The vertical part and the horizontal part of the frame body 1 are respectively provided with a first cavity 3-1 and a second cavity 3-2. Two rotatable driving shafts 3-3 are arranged in the first cavity 3-1. Transmission wheels 3-6 are arranged at the upper ends of the driving shafts 3-3. The transmission wheels 3-6 are connected by belt drive and can rotate synchronously. Two rotatable transmission screws 3-5 are arranged in the second cavity 3-2. Transmission gears 3-7 are arranged at the lower end of the driving shaft 3-3 and one end of the transmission screw 3-5 respectively and are meshed with each other. The transmission screw 3-5 can be driven to rotate by the driving shaft 3-3. A moving block 3-9 is connected to the outside of the transmission screw 3-5 by thread fit. Long holes 3-4 are opened on both surfaces in the second cavity 3-2. Both the upper and lower ends of the moving block 3-9 are located in the long holes 3-4. Long grooves 3-8 are opened on the surface of the opening support frame 2. Connecting grooves 3-10 are opened on the surface of the moving block 3-9. A connecting rod 3-11 is rotatably connected between the long groove 3-8 and the connecting groove 3-10 by a pin shaft. When the moving block 3-9 moves horizontally, the connecting rod 3-11 can be pushed, so that the connecting rod 3-11 pushes the opening support frame 2 upward, and the opening support frame 2 can be opened at a certain angle through the support and maintained at the adjusted angle to keep the opening state.

[0034] Furthermore, the catheter correction assembly 4 includes a pair of plugs 4-1 fixed at both ends of the frame body 1. A sleeve block 4-2 is sleeved and connected outside the plug 4-1. A round rod 4-3 is arranged on the side end surface of the sleeve block 4-2. A pipeline 4-4 is connected between the round rods 4-3.

[0035] In this embodiment, in order to achieve the effect of facilitating the insertion of the gastric lavage tube 4-4, a catheter correction assembly 4 is designed. Plugs 4-1 are provided at both front ends of the frame 1. A sleeve block 4-2 is sleeved and connected to the plug 4-1. A round rod 4-3 is provided on the side end face of the sleeve block 4-2. A tube 4-4 is connected between the round rods 4-3. After the sleeve connection, it can extend into the oral cavity, facilitating the insertion of the gastric lavage tube into the esophagus and then into the stomach through the tube 4-4.

[0036] Further, the opening support frame 2 is integrally in a portal structure, and an inclined plate 5 is provided at the front end of the opening support frame 2.

[0037] In this embodiment, through the portal-shaped structure of the opening support frame 2 and the installation of the inclined plate 5, it can fit the tooth shape of the oral cavity and can push against the teeth and then forcefully open.

[0038] Further, a screwing block 6 is provided at the upper end of the driving shaft 3-3 on one side inside the first cavity 3-1. The screwing block 6 is in a polygonal structure.

[0039] In this embodiment, by installing the polygonal screwing block 6 at the upper end of the driving shaft 3-3, it is convenient to screw and rotate the driving shaft 3-3.

[0040] Further, the opening support frame 2 can be rotated 45° at the pin shaft connection.

[0041] In this embodiment, through the 45° opening angle, the oral cavity can be fully opened to an operable size.

[0042] Further, the driving gears 3-7 at the lower end of the driving shaft 3-3 and the driving gears 3-7 at one end of the driving screw 3-5 both adopt bevel gears.

[0043] In this embodiment, through the structure of the bevel gears, the driving shaft 3-3 and the driving screw 3-5 can be driven in a 90° cooperation, making the angle of the driving shaft 3-3 more convenient to operate.

[0044] When in use, the frame 1 and the opening support frame 2 are sleeved at the oral cavity. The top of the frame 1 faces upward and is located above the head. Then, the teeth bite on the opening support frame 2 and the inclined plate 5. Then, the screwing block 6 is screwed, so that the driving shaft 3-3 drives the driving screw 3-5 through the driving gear 3-7 at the bottom, driving the moving block 3-9 to move linearly, pushing the connecting rod 3-11 to rotate the opening support frame 2 upward to open the oral cavity. The opening angle of the oral cavity can be controlled according to the moving position of the moving block 3-9. When it is necessary to insert a water pipe for gastric lavage, the tube 4-4 is sleeved on the plug 4-1 through the sleeve block 4-2, and then the water pipe is inserted into the tube 4-4 to start gastric lavage.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
