Description

Technical Field

[0001] This utility model relates to the field of retractor technology, specifically to an animal oral cavity examination retractor. Background Technology

[0002] In veterinary clinical practice, routine examinations of animal oral cavities, disease diagnosis, and treatment procedures are common needs. The process of opening the oral cavity of carnivores (such as canines, felines, and some wild carnivores) presents significant technical challenges due to their well-developed canine teeth and unique dentition structure.

[0003] Most existing retractors are designed with fixed dimensions, but there are significant interspecies differences in the length, spacing, and angle of canine teeth in carnivores. This makes it difficult for the retractor to be stably supported at both ends of the animal's canine teeth during examination, thus affecting the examination results and the accuracy of the veterinarian's operation.

[0004] Therefore, based on this, a design or technical improvement is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide an animal oral cavity examination retractor.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An animal oral cavity examination retractor includes a rectangular frame. First sliding blocks are slidably mounted on the outer surfaces of both the upper and lower ends of the rectangular frame. Two sets of guide rods are provided in the middle of the rectangular frame, and second sliding blocks are slidably mounted on the outer surfaces of both sets of guide rods. A connecting block is fixedly mounted on one side of each of the first sliding blocks, and threaded rods are rotatably mounted on the connecting block and the second sliding blocks. A movable plate is sleeved on the outer surface of the threaded rods, and two sets of limiting plates are provided at one end of the movable plate. A connecting plate is rotatably mounted between the two sets of limiting plates. A support plate is fixedly connected to one end of the connecting plate, and an annular toothed plate is provided at one end of the support plate. A limiting rod is provided on the connecting block and the second sliding blocks, and an installation block is sleeved on the outer surface of the limiting rod. One end of the installation block is fixedly connected to the movable plate. A drug delivery component is provided inside the annular toothed plate for delivering drugs into the animal cavity. A locking component is provided on the connecting plate and the movable plate to maintain the stability of the support plate.

[0008] Furthermore, the inner wall of the end of the annular toothed plate is provided with multiple sets of first annular grooves and multiple sets of second annular grooves. A drug storage tank is provided on the annular toothed plate. The drug injection assembly includes multiple sets of fixing tubes. The multiple sets of fixing tubes are respectively fixedly installed on the upper and lower sides of the inner wall of the drug storage tank. The inner walls of the multiple sets of fixing tubes are all connected with springs. One end of each spring is connected to a first movable rod and a second movable rod. A connecting rod is fixedly installed on the outer surface of the first movable rod and the second movable rod. The first movable rod and the second movable rod extend from the first annular groove and the multiple sets of second annular grooves, respectively. The length of the first movable rod is greater than that of the second movable rod. The outer surface of the first movable rod and the second movable rod is covered with rubber.

[0009] Furthermore, the top of the support plate is provided with a medicine replenishment hole, and the inner wall of the medicine replenishment hole is rotatably provided with a rotating cover. By rotating the rotating cover, the medicine replenishment hole can be opened to replenish the medicine.

[0010] Furthermore, the locking assembly includes a limiting screw that passes through the two sets of limiting plates and the connecting plate, and a locking nut is rotatably mounted on the outer surface of the limiting screw.

[0011] Furthermore, a knob is fixedly installed at the end of the threaded rod.

[0012] Furthermore, a connecting rod is fixedly installed at the middle of the rectangular frame, and a handle is fixedly installed at the middle of the connecting rod.

[0013] Furthermore, the outer surface of the grip is covered with a rubber sleeve.

[0014] Compared with existing technologies, the beneficial effects of this solution are:

[0015] 1. The end of the annular abutment plate is designed to fit over the canine teeth, thereby enhancing overall stability and effectively preventing slippage or instability. Furthermore, sliding the first and second sliding blocks allows for fine-tuning of the movable plate's position, enabling the retractor to fit snugly and adapt to the oral structures of animals of different sizes and shapes. This fine-tuning function not only improves the retractor's applicability but also ensures that veterinarians can accurately align the retractor with the canine teeth during examination, greatly facilitating subsequent oral examinations. Rotating the support plate to adjust the direction of the annular abutment plate enhances the retractor's flexibility and practicality.

[0016] 2. By rotating the limit screw and tightening the locking nut, the support plate can be firmly fixed, preventing the spreader from loosening during the inspection process, improving the stability of the spreader, and ensuring that the veterinarian can operate with peace of mind and accuracy during the inspection process.

[0017] 3. The threaded rod can be rotated by turning the knob, easily enabling the spreader to open. The movable plate, limited by the limiting rod, can only move up and down, ensuring a smooth and safe opening process. This improves veterinarian efficiency and provides animals with a more comfortable and safer examination experience.

[0018] 4. Multiple sets of first and second annular grooves arranged on the inner wall of the annular abutment plate, along with a drug storage tank, enable the storage and release of the medication. This improves drug utilization efficiency and ensures that the medication can be directly applied to the target area of ​​the animal, enhancing the therapeutic effect. Attached Figure Description

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figure 1-5 The illustrated animal oral cavity retractor includes a rectangular frame 1. First sliding blocks 2 are slidably mounted on the outer surfaces of both the upper and lower ends of the rectangular frame 1. Two sets of guide rods 4 are disposed in the middle of the rectangular frame 1. Second sliding blocks 6 are slidably mounted on the outer surfaces of both sets of guide rods 4. A connecting block 3 is fixedly mounted on one side of each of the first sliding blocks 2. Threaded rods 7 are rotatably mounted on the connecting block 3 and the second sliding blocks 6. A movable plate 8 is sleeved on the outer surface of the threaded rod 7. Two sets of limiting plates 511 are disposed at one end of the movable plate 8. A connecting plate 5 is rotatably mounted between the two sets of limiting plates 511. A support plate is fixedly connected to one end of the connecting plate 5. 111, and one end of the support plate 111 is provided with an annular toothed plate 112. The connecting block 3 and the second sliding block 6 are provided with a limiting rod 311, and the outer surface of the limiting rod 311 is fitted with an installation block 312. The limiting rod 311 ensures that the movable plate 8 can move up and down and remain stable, and will not deviate or shake due to external force. One end of the installation block 312 is fixedly connected to the movable plate 8. The annular toothed plate 112 is provided with a drug injection component for drug delivery to the animal cavity. The connecting plate 5 and the movable plate 8 are provided with a locking component for maintaining the stability of the support plate 111.

[0028] In one embodiment, multiple sets of first annular grooves 613 and multiple sets of second annular grooves 619 are formed on the inner wall of the end of the annular abutment plate 112. A drug storage tank 617 is formed on the annular abutment plate 112. The drug injection assembly includes multiple sets of fixing tubes 614, which are respectively fixedly installed on the upper and lower sides of the inner wall of the drug storage tank 617. The inner walls of the multiple sets of fixing tubes 614 are all connected to springs. One end of the spring is respectively connected to a first movable rod 612 and a second movable rod 615. The first movable rod 612 and the second movable rod 615 are connected to each other. A connecting rod 616 is fixedly installed on the outer surface, and the first movable rod 612 and the second movable rod 615 extend from the first annular groove 613 and multiple sets of second annular grooves 619, respectively. The length of the first movable rod 612 is greater than that of the second movable rod 615. The outer surfaces of the first movable rod 612 and the second movable rod 615 are covered with rubber to increase the sealing of the movable rods in the annular grooves. When the inner wall of the annular abutment plate 112 is fitted onto the canine tooth, the canine tooth will first contact the first movable rod 612 as the movable plate 8 moves. Under the elastic force of the spring, the first movable rod 612 can smoothly retract into the second annular groove 619. Since the first movable rod 612 is firmly connected to the second movable rod 615 through the connecting rod 616, the movement of the first movable rod 612 will move the second movable rod 615 together. It is worth noting that the second movable rod 615 is smaller than the first movable rod 612. This allows the second movable rod 615 to open the first annular groove 613 during its retraction, thereby allowing the medicine in the medicine storage tank 617 to flow out smoothly. The medicine can be an anti-inflammatory medicine or an anesthetic medicine, which can be used according to the actual condition of the animal to improve the efficiency of treatment.

[0029] In one embodiment, a medicine replenishment hole 618 is provided at the top of the support plate 111, and a rotating cover 611 is rotatably provided on the inner wall of the medicine replenishment hole 618. The medicine replenishment hole 618 can be opened by rotating the rotating cover 611, so as to replenish the medicine.

[0030] In one embodiment, the locking assembly includes a limiting screw 113 passing through the two sets of limiting plates 511 and the connecting plate 5, and a locking nut 114 is rotatably mounted on the outer surface of the limiting screw 113. By rotating the locking nut 114, the connecting plate 5 and the two sets of limiting plates 511 can be fixed, thereby maintaining the stability of the support plate 111. This ensures that the retractor can be firmly fixed in the animal's mouth during use, avoiding the risk of examination failure or animal injury due to the retractor loosening.

[0031] In one embodiment, a knob 211 is fixedly installed at the top of the threaded rod 7. The rotation of the threaded rod can be easily driven by rotating the knob 211, which not only increases the convenience of operation but also improves the user's hand comfort. At the same time, it can more accurately control the degree of opening of the spreader, thereby ensuring the accuracy and safety of the inspection.

[0032] In one embodiment, a connecting rod 411 is fixedly installed at the middle of the rectangular frame 1, and a handle 412 is fixedly installed at the middle of the connecting rod 411. The outer surface of the handle 412 is covered with a rubber sleeve 413. The handle 412 makes it convenient to hold and operate the spreader, and the rubber increases the comfort and anti-slip performance of the grip, which can reduce the fatigue of the user's hand caused by holding for a long time.

[0033] Workflow: First, the two sets of annular tooth-holding plates 112 are placed close together to facilitate entry into the animal's mouth. Based on the size and shape of the animal's mouth, the first sliding block 2 and the second sliding block 6 are slid to fine-tune the lateral position of the movable plate 8, ensuring the retractor adapts to the animal's oral structure. Then, the support plate 111 is rotated to adjust the direction of the annular tooth-holding plates 112, ensuring they are accurately aligned with the canine teeth. The annular tooth-holding plates 112 are gently placed on the canine teeth. The locking assembly is then used, i.e., rotating the limiting screw 113 and tightening the locking nut 114, to ensure the stability of the support plate 111 and prevent the retractor from loosening during inspection. Finally, the knob 211 is rotated, causing the threaded rod 7 to rotate. The movable plate 8, limited by the limiting rod 311, can only move up and down. Therefore, as the threaded rod 7 rotates, the movable plate 8 will cause the support plate 111 and the annular tooth-holding plates 112 to move upwards, thereby opening the animal's mouth for veterinary examination.

[0034] When the inner wall of the annular abutment plate 112 is fitted onto the canine tooth, the canine tooth will first contact the first movable rod 612 as the movable plate 8 moves. Under the elastic force of the spring, the first movable rod 612 can smoothly retract into the second annular groove 619. Since the first movable rod 612 is securely connected to the second movable rod 615 through the connecting rod 616, the movement of the first movable rod 612 will move the second movable rod 615 together. It is worth noting that the size of the second movable rod 615 is smaller than that of the first movable rod 612, which allows it to open the first annular groove 613 during the retraction of the second movable rod 615, thereby allowing the medicine in the medicine reservoir 617 to flow out smoothly, thus playing a direct therapeutic role.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
