Abstract
Description
Technical Field
[0001] This utility model belongs to the field of veterinary instrument technology, and in particular relates to a veterinary anti-pinch vaginal opening device. Background Technology
[0002] In veterinary clinical practice, the vaginal speculum is an important tool for assisting in the examination of the female animal's reproductive system and determining estrus status, and is widely used in the reproductive management of livestock such as cattle and sheep. However, in actual use, because animals need to be restrained, their movement is restricted, and they are prone to sudden movements due to tension, discomfort, or fright. At this time, the veterinarian may not be able to remove the vaginal speculum in time, or may not be able to quickly release the closing pressure of the blades during the operation, causing the blades of the vaginal speculum to compress or even pinch the animal's vaginal wall when it is fully closed, leading to problems such as vaginal bleeding and tissue damage.
[0003] Such mechanical trauma not only causes pain and discomfort to animals, significantly affecting their physiological state, but also increases the risk of vaginal infections. In severe cases, it can lead to inflammation, scarring, and even affect conception rates and reproductive performance. Furthermore, vaginal injury may interfere with the accurate assessment of estrus in female animals, reducing the success rate of artificial insemination and causing unnecessary economic losses to the livestock industry. Utility Model Content
[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: A veterinary anti-pinch vaginal opening device includes a lower blade, an upper blade, and an adjusting handle. One end of the lower blade is connected to a handle, and a bolt is fixedly installed on one side of the handle. The end of the bolt passes through a groove in the adjusting handle and is threadedly connected to a nut. The two sides of one end of the upper blade are rotatably connected to the two sides of the upper end of the adjusting handle, respectively. An anti-pinch mechanism auxiliary device is installed between the lower blade and the upper blade for use.
[0005] Preferably, a side handle is fixedly installed on one side of the upper blade, and a bolt is fixedly installed on one side of the adjustment handle. The bolt passes through the long groove opened in the side handle and is threadedly connected to the nut.
[0006] Preferably, the anti-pinch mechanism includes a pair of fulcrums, which are respectively installed on both sides of the lower blade near the root, and a support groove is opened at the corresponding position of the upper blade.
[0007] Preferably, when the upper blade and the lower blade are closed, the fulcrum and the support groove are in contact with each other to restrict the blade from being completely closed, so that a gap of 2 to 3 mm is maintained between the blades.
[0008] Preferably, the anti-pinch mechanism further includes a pair of covering layers, which are located at the edges of the lower and upper blades respectively. The covering layers are made of medical-grade silicone or polyurethane and are used to buffer the pressure on the vaginal wall when the blades are closed.
[0009] Preferably, each of the two covering layers is provided with a plurality of locking blocks, and a plurality of locking slots are provided at the edges of the upper and lower blades, with the locking blocks engaging with the locking slots.
[0010] Preferably, a pad is provided near the root of the covering layer located at the upper blade.
[0011] Preferably, the anti-pinch mechanism further includes a limiting mechanism. The limiting mechanism is provided with a screw threadedly connected to the handle. The other end of the screw rotates inside the sleeve. A hollow rod is fixedly provided at the upper end of the sleeve. A sliding rod is slidably provided inside the hollow rod. A top rod is connected to the upper end of the sliding rod. The top rod is inserted into the positioning groove opened on the edge of the upper blade.
[0012] Preferably, a spring connects the hollow rod and the sliding rod.
[0013] Preferably, the sleeve has a rotating groove, and the annular block on the outside of the screw rotates in the rotating groove.
[0014] The veterinary anti-pinch vaginal opening device of this utility model has the following advantages:
[0015] 1. This veterinary anti-pinch vaginal opening device has fulcrums installed on both sides of the root edge of the two blades of the opening device. This design ensures that when the blades are closed, they cannot be completely closed and always maintain a gap of 2-3 mm. This specific structure effectively prevents the opening device from pinching the animal's vaginal wall that may be caused by complete closure during use, thereby significantly reducing the risk of vaginal trauma and bleeding.
[0016] 2. This veterinary anti-pinch vaginal opening device utilizes a covering layer or a limiting mechanism instead of a fulcrum. The covering layer adds a protective layer without altering the original structure, reducing the risk of injury from direct contact with hard materials. The limiting mechanism prevents sudden closure of the upper and lower blades under force, ensuring that even improper operation avoids any damage to the animal's vagina. These two methods not only improve the safety and reliability of the equipment but also enhance the efficiency of veterinary procedures and animal welfare, reducing the incidence of complications due to improper instrument use, and contributing to improved health and reproductive success in female animals.

[0026] like Figure 1 and Figure 3 As shown, this utility model discloses a veterinary anti-pinch vaginal opening device, which includes a lower blade 1, an upper blade 2, and an adjusting handle 4. One end of the lower blade 1 is connected to a handle 11, and a bolt 12 is fixedly installed on one side of the handle 11. The end of the bolt 12 passes through a sliding groove 43 opened in the adjusting handle 4 and is threadedly connected to a nut 13. By pushing the adjusting handle 4 upward, the upper blade 2 can be moved upward and separated from the lower blade 1. Then, by tightening the nut 13, the adjusting handle 4 can be locked in the desired position, thereby realizing the adjustment and fixation of the opening degree between the two blades.
[0027] Furthermore, in order to achieve more precise angle adjustment, a side handle 21 is fixedly installed on one side of the upper blade 2, and a bolt 41 is fixedly installed on one side of the adjusting handle 4. The bolt 41 passes through the long groove 22 opened in the side handle 21 and is threadedly connected to the nut 42. The two sides of one end of the upper blade 2 are respectively rotatably connected to the two sides of the upper end of the adjusting handle 4. By rotating the upper blade 2, the distance between the upper and lower blades can be flexibly adjusted within a certain range to adapt to the needs of livestock of different body sizes or physiological states, thereby improving the applicability and ease of operation of the equipment.
[0028] Example 1
[0029] like Figure 2As shown, an anti-pinch mechanism is installed between the lower blade 1 and the upper blade 2. The anti-pinch mechanism includes a pair of fulcrums 3, which are respectively installed on both sides of the lower blade 1 near the root. A support groove 31 is opened at the corresponding position of the upper blade 2. When the upper blade 2 and the lower blade 1 are closed, the fulcrums 3 and the support groove 31 contact each other to restrict the blades from closing completely, so that a gap of 2-3 mm is maintained between the blades to prevent pinching injury to the vaginal wall of the animal.
[0030] Example 2
[0031] like Figure 4 and Figure 5 As shown, the anti-pinch mechanism also includes a pair of covering layers 32, respectively disposed at the edges of the lower blade 1 and the upper blade 2. The covering layers 32 are made of medical-grade silicone or polyurethane, which are biocompatible and elastic materials. They are used to apply buffering pressure to the vaginal wall during the closure of the blades, thereby effectively reducing direct contact between the hard metal edge and the tissue and preventing mechanical damage caused by friction or compression. The cross-section of the covering layer 32 has an arc-shaped convex structure, with its highest point extending approximately 0.5 to 1 mm beyond the metal edge of the blade. This ensures that when the upper and lower blades are closed, only the covering layer 32 preferentially contacts the animal's vaginal wall, while the metal body does not directly contact it, further improving safety and comfort during use.
[0032] A pad 35 is provided near the root of the covering layer 32 located at the upper blade 2. When the upper and lower blades are closed, the pad 35 preferentially contacts the lower covering layer 32, thereby keeping the front ends of the two sets of covering layers 32 at a certain distance without contacting each other, avoiding the risk of pinching injury caused by excessive closure.
[0033] Furthermore, to enable the removable and replaceable covering layer 32, several locking blocks 34 are provided on the inner side of each pair of covering layers 32. Correspondingly, multiple matching slots 33 are provided at the edges of the lower blade 1 and the upper blade 2. Through the locking engagement of the locking blocks 34 and the slots 33, the covering layer 32 can be quickly installed and replaced, facilitating cleaning and disinfection, and replacement of parts according to wear conditions. This extends the overall service life of the equipment and improves the hygiene and safety and ease of operation in clinical use.
[0034] Example 3
[0035] like Figures 6 to 8 As shown, based on the aforementioned adjustment structure, a limiting mechanism 37 is further included to prevent the upper and lower blades from closing completely, so as to effectively protect the animal's vaginal wall and reduce the risk of pinching injury caused by accidental contact or sudden movement of the animal during operation.
[0036] The limiting mechanism 37 includes a screw 371, one end of which is threadedly connected to the handle 11 of the lower blade 1, and the other end is rotatably disposed inside the sleeve 372. A hollow rod 373 is fixedly connected to the upper end of the sleeve 372, and a sliding rod 375 is slidably fitted inside the hollow rod 373. A push rod 376 is connected to the upper end of the sliding rod 375, and the push rod 376 is used to engage with the positioning groove 36 opened on the edge of the upper blade 2.
[0037] A spring 374 is provided between the hollow rod 373 and the slide rod 375 to provide upward elastic support. When the upper blade 2 closes downward, the positioning groove 36 on its edge will contact the push rod 376. At this time, the push rod 376 is compressed and drives the slide rod 375 to compress the spring 374 downward, thereby generating a buffering effect to prevent the upper blade 2 and the lower blade 1 from completely closing and to always maintain a certain gap, effectively avoiding mechanical damage to the vaginal wall.
[0038] Furthermore, the sleeve 372 has a rotating groove 377 inside, and the screw 371 has an annular block on its outer periphery. The annular block is embedded in the rotating groove 377 and can rotate freely therein. The limiting mechanism 37 not only realizes the automatic limitation of the degree of blade closure, but also improves the safety and durability of the overall device through the spring 374 buffer structure, effectively preventing equipment damage or tissue damage caused by excessive closing force.
