Description

Technical Field

[0001] The utility model belongs to the technical field of oral dilators, and specifically relates to an animal husbandry oral dilator. Background Art

[0002] In veterinary practice, oral treatment is an important link in ensuring animal health. Especially for large livestock animals with long snouts such as donkeys, horses, and certain dog breeds, inspections, surgeries, and treatment operations inside the oral cavity often face many challenges. During traditional oral treatment, due to the lack of tools specifically designed for the oral structures of these specific animals, veterinarians often encounter problems such as inconvenient operation, limited vision, and animal discomfort, which seriously restrict the treatment effect and animal welfare.

[0003] The disadvantages of traditional animal husbandry oral dilators are mainly reflected in the following aspects: Most existing oral dilators are designed as general-purpose types and do not fully consider the differences in the oral cavities of animals of different species and sizes. As a result, during use, they are either too large to be stably fixed or too small to fully open the oral cavity, affecting the accuracy and safety of the operation. Traditional dilators often require veterinarians to manually keep the animal's oral cavity open continuously. This not only increases the difficulty of the surgical operation but also may lead to operation errors due to hand fatigue. At the same time, the lack of an effective fixation mechanism makes the open state unstable and prone to slipping. The hard and non-personalized design is likely to cause compression or scratches to the soft tissues of the animal's oral cavity, especially during long surgeries, increasing the risk of postoperative infection and affecting the recovery of the animal. Summary of the Utility Model

[0004] In view of this, the utility model provides an animal husbandry oral dilator, which solves the disadvantages that traditional oral dilators do not fully consider the differences in the oral cavities of animals of different species and sizes, and improves the adaptability and accuracy of treatment.

[0005] The utility model is implemented as follows:

[0006] The utility model provides an animal husbandry oral dilator, which includes at least two telescopic rod bodies, a mouthpiece, and a mechanical locking mechanism. The mechanical locking mechanism is arranged between each section of the telescopic rod bodies. The telescopic rod bodies are composed of at least two mutually sleeved tubular structures. The inner wall of each tubular structure forms a sliding fit with the outer wall of the adjacent tubular structure. The mouthpiece is an annular structure with one end open and the other end closed. A protrusion is arranged on the side of the mouthpiece close to the animal's oral cavity. An adjustment ring is equipped on the outer edge of the mouthpiece, and the opening size of the mouthpiece is changed by rotating the adjustment ring;

[0007] Wherein, the outer surface of the telescopic rod body is covered with an anti-slip layer.

[0008] The anti-slip layer is made of rubber or an anti-slip coating. The material of the anti-slip coating can be medical-grade rubber or silicone resin composite material, which has excellent friction coefficient, good biocompatibility and durability, and can still maintain good grasping performance in a wet or greasy environment. In addition, the coating material may also contain antibacterial components to improve the hygiene level during use.

[0009] On the basis of the above technical solutions, an animal husbandry oral retractor of the present utility model can also be improved as follows:

[0010] Wherein, the mouthpiece is connected to the end of the outermost section of the telescopic rod body through a quick-release joint.

[0011] The components of the quick-release joint include: a joint body, one end of which is fixed to the inner side of the mouthpiece and the other end is provided with a connection structure; a docking lock, located at the end of the telescopic rod body, designed with a locking groove or tenon matching the joint body; and a release button, integrated on the joint body or the docking lock, which can quickly release the locked state when pressed, facilitating quick disassembly and assembly.

[0012] Further, the diameter of the mouthpiece is greater than or equal to 1.1 times the diameter of the end of the outermost section of the telescopic rod body.

[0013] Further, the shape of the mouthpiece is designed as an oval or a conical ring structure, and its cross-section gradually decreases along the axial direction from the open end to the closed end.

[0014] Specifically, the cross-sectional profile of the mouthpiece can be:

[0015] Oval cross-section: The long axis direction is consistent with the natural opening direction of the animal's oral cavity, and the short axis direction provides necessary lateral support to ensure sealing and comfort.

[0016] Slightly conical cross-section: The conical design that gradually narrows from the entrance to the depth helps to guide the mouthpiece deep into the oral cavity and naturally adapt to the morphological changes inside the oral cavity, while reducing the irritation to the animal.

[0017] In addition, the inner surface of the mouthpiece can be designed with slightly convex contour lines or wavy patterns to increase the friction and sealing performance when contacting the animal's oral cavity, and avoid slipping during use.

[0018] Further, the material of the mouthpiece is selected from biocompatible soft materials, the protrusions are made of hard materials such as medical-grade plastics or metal alloys, and the surface of the mouthpiece has anti-slip textures.

[0019] Biocompatible soft materials specifically refer to medical-grade materials that meet the ISO 10993 standard, such as medical-grade silicone rubber, polyurethane, thermoplastic elastomer (TPE), or specific biocompatible synthetic rubbers. These materials not only have good softness and elasticity, can adapt to and protect animal oral tissues, but also ensure that they will not cause adverse reactions in organisms, such as allergies and inflammations, during long-term contact or short-term surgeries.

[0020] Furthermore, the telescopic ratio range of the telescopic rod body is set between 1:1.5 and 1:2.

[0021] Furthermore, the thickness of the mouthpiece is designed to be 2 - 5 mm.

[0022] Furthermore, the mechanical locking mechanism is specifically a ratchet mechanism or a screw locking mechanism.

[0023] Furthermore, the ratchet mechanism includes a ratchet rack installed on the outside of at least one section of the telescopic rod body, and a ratchet handle that cooperates with the ratchet rack. The length between the telescopic rod bodies is locked and unlocked by rotating the ratchet handle.

[0024] Furthermore, the screw locking mechanism includes an external threaded rod body and an internal thread engaging member. By rotating, the two are mutually engaged or separated, thereby adjusting the total length of the telescopic rod body.

[0025] Compared with the prior art, the beneficial effects of a livestock oral retractor provided by the present utility model are as follows:

[0026] Highly adjustable: By introducing the telescopic rod body design and cooperating with a precise ratchet or screw locking mechanism, the retractor can be precisely adjusted according to the oral cavity size of specific animals, ensuring a perfect fit every time, and greatly improving the adaptability and precision of treatment;

[0027] Enhanced stability and comfort: The innovative mouthpiece design can not only effectively close and fix the animal's oral cavity, but the elastic protrusions inside automatically expand the oral cavity when the rod body is inserted, reducing the discomfort of the animal. At the same time, the anti-slip texture and adjustable size design of the mouthpiece ensure stability during the operation process and reduce the risk of slipping;

[0028] Reduced risk of injury: The mouthpiece is made of biocompatible soft materials, and the inner surface is designed with a protective structure, reducing damage to the oral soft tissues and improving the comfort and safety of animals;

[0029] Optimized surgical field of view: The internal structure design of the mouthpiece takes into account light guidance, and an internal lighting device can be optionally equipped. Combining its shape and position design, it significantly improves the surgical field of view and facilitates veterinarians to perform delicate operations;

[0030] Simple and fast operation: The design of the quick-release connector makes the installation and removal of the nozzle extremely convenient, while the ratchet or screw locking mechanism ensures quick and reliable length adjustment, greatly improving the efficiency of surgical preparation and operation.

[0065] Furthermore, in the above technical solution, the shape of the mouthpiece 20 is designed to be an elliptical or conical ring structure, and its cross section gradually decreases from the open end to the closed end along the axial direction.

[0066] Furthermore, in the above technical solution, the material of the mouthpiece 20 is selected from a biocompatible soft material, and the surface of the mouthpiece 20 has an anti-slip texture.

[0067] When in use, the anti-slip texture includes but is not limited to:

[0068] Micro-convex dot array: evenly distributed tiny convex dots are set on the inner and / or outer surface of the mouthpiece to increase the friction with the mouth or hand and prevent slipping.

[0069] Spiral pattern: Spiral patterns are designed along the axial or radial direction of the mouthpiece, which is convenient for holding during operation and also helps to stabilize the position in the animal's mouth.

[0075] The spiral locking mechanism comprises an externally threaded rod body and an internally threaded joint, which are engaged with or separated from each other by rotation, thereby adjusting the total length of the telescopic rod body 10.

[0076] When a spiral locking mechanism is used as a mechanical locking mechanism, the following key components are included:

[0077] Externally threaded rod section: located at the end of the outermost telescopic rod, with continuous spiral lines processed on its outer surface;

[0078] Internal thread joint: designed to be rotatably sleeved on the end of the external thread rod section, with the inner wall having internal threads matching the external threads;

[0079] Manual knob: It is fixedly connected to the internal thread engaging member. By rotating the manual knob, the internal thread engaging member is driven to move axially along the outer threaded rod body section, thereby adjusting the telescopic length of the rod body.

[0080] Anti-loosening device: To prevent the knob from loosening due to vibration or other reasons during use, a locking screw or a detent pin is designed to ensure the stability of the locked state.

[0081] Adjustment operation: The manual knob can be provided with graduations or a sense of rotational resistance to help the operator control the length of the rod body and achieve stable locking. By gradually rotating the knob until the desired length is reached and a locking signal is heard or felt, the adjustment can be completed.

[0082] Such as Figure 1 、 Figure 2 As shown, the third embodiment of a livestock oral retractor provided by the present utility model specifically includes the following steps:

[0083] Veterinarian preparation stage:

[0084] Check the integrity of the equipment: Ensure that all components of the telescopic rod body, mouthpiece, elastic protrusion, adjustment ring, and mechanical locking mechanism are intact, without deformation or damage.

[0085] Length adjustment: According to the estimated depth of the animal's oral cavity, adjust the total length of the telescopic rod body through the mechanical locking mechanism. If a ratchet mechanism is used, rotate the ratchet handle until a "click" sound is heard, indicating that it is locked; if it is a screw locking mechanism, rotate the manual knob to an appropriate length and ensure that the anti-loosening device is correctly set.

[0086] Install the mouthpiece:

[0087] Adjust the size of the mouthpiece: Use the adjustment ring to rotate and adjust the opening size of the mouthpiece to ensure that it can fit tightly against the front end of the animal's oral cavity without hindering breathing.

[0088] Install the elastic protrusion: Confirm that the hard front end of the elastic protrusion faces towards the inside of the oral cavity, and the elastic rear end is properly connected to the elastic connection structure inside the mouthpiece.

[0089] Connect the quick-release joint: Connect the mouthpiece to the end of the telescopic rod body through the quick-release joint, and press the release button to ensure that the two are firmly locked.

[0090] Operation process:

[0091] Gentle insertion: Hold the rod body and slowly and gently insert the mouthpiece into the animal's oral cavity. Use the hard part at the front end of the elastic protrusion to naturally push open both sides of the oral cavity until the mouthpiece completely fits against the animal's lip edge.

[0092] Position Confirmation and Fixation: Check whether the mouthpiece is firmly and comfortably fixed at the front end of the animal's oral cavity, confirm that the animal's breathing is not affected, and fine-tune the position of the mouthpiece if necessary.

[0093] Start Treatment: After ensuring that the oral cavity is fully opened and the animal is stable, the veterinarian can start internal oral examinations, cleaning, surgeries, or other treatment operations.

[0094] Post-operative Treatment and Maintenance:

[0095] Unlock: After the treatment is completed, operate the mechanical locking mechanism in reverse to shorten the length of the telescopic rod body for easy removal.

[0096] Cleaning and Disinfection: Separate the mouthpiece, elastic protrusions, and other detachable components from the telescopic rod body, thoroughly clean all components with an appropriate disinfectant solution, ensure aseptic storage, and prepare for the next use.

[0097] Specifically, the principle of the present utility model is:

[0098] Telescopic Rod Body and Mechanical Locking: Using mechanical engineering principles, a ratchet or screw locking mechanism is designed to achieve precise adjustment of the rod body length. The ratchet mechanism realizes locking through the cooperation of the ratchet rack and the ratchet handle, and the one-way movement of the pawl. Screw locking is achieved through the rotational cooperation of external and internal threads, and the use of friction and locking devices to ensure stability. This design ensures that the retractor can be firmly locked at any required length, and the supporting force is stable and reliable;

[0099] Mouthpiece Design and Elastic Protrusions: The shape and material selection of the mouthpiece are based on the anatomical characteristics of the animal's oral cavity. Its conical or elliptical cross-section and the internal elastic protrusion structure ensure the maximum opening effect under the minimum pressure through mechanical analysis, while reducing the pressure on the animal. The distribution and elastic coefficient of the elastic protrusions are precisely calculated to effectively open the oral cavity and avoid unnecessary damage to sensitive tissues;

[0100] Anti-slip and Biocompatibility: The selected anti-slip materials and biocompatible soft materials not only improve the stability and safety during operation but also fully consider the animal's physiological response to ensure that the materials do not cause rejection or allergy when in contact with oral tissues, promoting post-operative healing;

[0101] Overall Synergistic Effect: The organic combination of each component realizes a comprehensive improvement from operation convenience, safety to treatment effect, ensuring that during oral treatment of livestock animals with a longer snout, various examinations and surgical operations can be completed more efficiently, safely, and comfortably, greatly promoting the progress of veterinary oral treatment technology and improving the standard of animal care.
