Description

Technical Field

[0001] This invention relates to castration clamp technology, specifically to a non-slip castration clamp for animal husbandry and veterinary use. Background Technology

[0002] In animal husbandry and veterinary clinical practice, castration surgery on livestock such as cattle and sheep is a common management practice. Among these methods, the elastic bloodless castration method is widely used due to its advantages of minimal trauma, less bleeding, and faster recovery. The core procedure involves placing a highly elastic rubber castration ring at the base of the animal's scrotum. The continuous pressure of the rubber ring cuts off the blood supply to the testicles, causing ischemic necrosis and subsequent spontaneous detachment, thus achieving castration. However, in practice, installing the rubber castration ring presents some difficulties.

[0003] Currently, the traditional method relies entirely on veterinarians manually stretching the rubber band using hand-held castration forceps. This involves hooking the edge of the rubber band with the forceps and manually prying it open to a sufficient diameter before inserting it into the base of the scrotum. Because the rubber band is highly elastic and has strong tension, manually stretching it requires considerable finger strength and skill, making it extremely laborious and time-consuming. This is especially true when multiple animals need to be castrated consecutively, as veterinarians' hands easily become fatigued, significantly reducing operational efficiency and making it difficult to meet the needs of large-scale farming. Summary of the Invention

[0004] The purpose of this invention is to provide a non-slip castration clamp for animal husbandry and veterinary medicine, so as to solve the problem that the existing technology relies entirely on veterinarians to manually stretch the rubber ring with hand-held dilator castration clamps, which results in laborious operation and low castration efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a non-slip castration clamp for animal husbandry and veterinary medicine, comprising a mounting plate, a transmission box rotatably connected to one side of the mounting plate, a first driving mechanism for driving the transmission box to rotate around its own axis connected to the outer surface of the transmission box, a plurality of transmission racks slidably connected to the transmission box, a transmission mechanism for driving the transmission racks to move horizontally connected to the outer surface of the transmission racks, and a fixing hook fixedly connected to one end of the transmission racks;

[0006] The fixing hook has an arc-shaped anti-slip fixing groove, and a support block is fixedly connected to the outer surface of the fixing hook. A rubber castration ring body is slidably connected in the arc-shaped anti-slip fixing groove, and multiple friction particles are fixedly connected to the inner surface of the rubber castration ring body.

[0007] Furthermore, the transmission mechanism includes a first transmission gear ring rotatably connected to the transmission box, a first transmission gear meshing with the inner surface of the first transmission gear ring, a first transmission shaft rotatably connected to the transmission box being fixedly sleeved in the middle of the first transmission gear, a second transmission gear being fixedly sleeved on the outer surface of the first transmission shaft, the outer surface of the second transmission gear meshing with a transmission rack, and a second drive mechanism for driving rotation about its own axis being connected to the inner surface of the first transmission gear ring.

[0008] Furthermore, the second drive mechanism includes a first rotation drive member fixedly connected to the transmission box, a second drive shaft fixedly connected to the output end of the first rotation drive member, the second drive shaft being rotatably connected to the transmission box, and a third drive gear fixedly sleeved on the outer surface of the second drive shaft, the third drive gear meshing with the first drive gear ring.

[0009] Furthermore, the first driving mechanism includes a second rotating driving member fixedly connected to the mounting ring plate, and a driving gear is fixedly sleeved at the output end of the second rotating driving member. The outer surface of the driving gear is meshed with a second transmission gear ring fixedly sleeved to the transmission box.

[0010] Furthermore, a through groove is provided through the transmission rack, one end of the transmission rack is fixedly connected to a water spray head communicating with the through groove, the other end of the transmission rack is fixedly connected to a connecting pipe communicating with the through groove, one end of the connecting pipe is fixedly connected to a water supply mechanism connected to the mounting ring plate, and the water supply mechanism is used to supply water to the connecting pipe.

[0011] Furthermore, the water supply mechanism includes a water tank fixedly connected to the mounting ring plate, a water pump fixedly connected to one side of the water tank via a pipe, a water supply pipe fixedly connected to the outlet end of the water pump, a water supply ring pipe fixedly connected to one end of the water supply pipe, and a flexible hose connected to the connecting pipe fixedly connected to the outer surface of the water supply ring pipe.

[0012] Furthermore, an inlet pipe is fixedly connected to the top of the water tank, and a sealing plug is threaded to the top of the inlet pipe.

[0013] Furthermore, a handle is fixedly connected to one side of the mounting ring plate, and a storage battery is fixedly connected to the mounting ring plate.

[0014] Compared with the prior art, the anti-slip castration forceps for animal husbandry and veterinary medicine provided by the present invention has the following beneficial effects:

[0015] By setting up an installation ring plate, transmission box, multiple transmission racks, and fixing hooks, in conjunction with a transmission mechanism consisting of a first transmission gear ring, a first transmission gear, a first transmission shaft, and a second transmission gear, and a second drive mechanism driven by a servo motor, multiple fixing hooks can synchronously expand radially outward or retract inward from the center position. During castration surgery, simply insert the rubber castration ring body into the arc-shaped anti-slip fixing groove, and the second drive mechanism drives the transmission racks to move, automatically and evenly expanding the rubber castration ring body to the required diameter. The entire process eliminates the need for manual pulling and expansion by the veterinarian, significantly reducing operational difficulty and physical exertion. This is particularly suitable for castration operations on large numbers of cattle and sheep, further improving the efficiency of veterinary castration surgeries.

[0016] At the same time, the simultaneous application of force by multiple fixing hooks ensures that the rubber castration ring is evenly stressed in the circumferential direction during the opening process, eliminating the risk of the rubber ring breaking or deforming due to excessive local tension, and significantly improving the success rate of the operation and the safety of the procedure.

[0017] By creating a through groove within the transmission rack and installing connected spray heads and pipes at both ends, along with a water supply mechanism consisting of a water tank, pump, supply pipe, supply ring pipe, and hose, disinfectant can be automatically sprayed from the spray head through the groove after the rubber castration ring is tightened around the base of the scrotum, providing immediate disinfection of the tightened area. Simultaneously, the first drive mechanism rotates the transmission box, causing the spray head to swing synchronously with the transmission rack, achieving comprehensive and even spraying of the annular area around the base of the scrotum. This effectively solves the problem of incomplete postoperative disinfection or the need for manual application of disinfectant in traditional surgeries, significantly reducing the risk of postoperative infection.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Please see Figures 1 to 7 As shown, the present invention provides anti-slip castration pliers for animal husbandry and veterinary use, including a mounting plate 1. A transmission box 2 is rotatably connected to one side of the mounting plate 1. A first driving mechanism for driving the transmission box 2 to rotate around its own axis is connected to the outer surface of the transmission box 2. A plurality of transmission racks 3 are slidably connected to the transmission box 2. A transmission mechanism for driving the transmission racks 3 to move horizontally is connected to the outer surface of the transmission racks 3. A fixing hook 4 is fixedly connected to one end of the transmission racks 3.

[0031] The fixing hook 4 has an arc-shaped anti-slip fixing groove 5. A support block 6 is fixedly connected to the outer surface of the fixing hook 4. A rubber castration ring body 7 is slidably connected in the arc-shaped anti-slip fixing groove 5. Multiple friction particles 8 are fixedly connected to the inner surface of the rubber castration ring body 7.

[0032] The transmission mechanism includes a first transmission gear ring 11 rotatably connected to the transmission box 2. A first transmission gear 12 is meshed with the inner surface of the first transmission gear ring 11. A first transmission shaft 13 rotatably connected to the transmission box 2 is fixedly sleeved in the middle of the first transmission gear 12. A second transmission gear 14 is fixedly sleeved on the outer surface of the first transmission shaft 13. The outer surface of the second transmission gear 14 meshes with the transmission rack 3. A second drive mechanism for driving the first transmission gear ring 11 to rotate around its own axis is connected to the inner surface of the first transmission gear ring 11.

[0033] The second drive mechanism includes a first rotation drive component 21 fixedly connected to the transmission box 2. The first rotation drive component 21 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles. The output end of the first rotation drive component 21 is fixedly connected to a second transmission shaft 22. The second transmission shaft 22 is rotatably connected to the transmission box 2. A third transmission gear 23 is fixedly sleeved on the outer surface of the second transmission shaft 22. The third transmission gear 23 meshes with a first transmission gear ring 11. The first rotation drive component 21 drives the second transmission shaft 22 to rotate, the second transmission shaft 22 drives the third transmission gear 23 to rotate, and the third transmission gear 23 drives the first transmission gear ring 11 to rotate.

[0034] The first driving mechanism includes a second rotation driving component 31 fixedly connected to the mounting ring plate 1. The second rotation driving component 31 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles. A drive gear 32 is fixedly sleeved on the output end of the second rotation driving component 31. A second transmission gear ring 33 fixedly sleeved on the outer surface of the drive gear 32 is meshed with the transmission box 2. The second rotation driving component 31 drives the drive gear 32 to rotate, and the drive gear 32 drives the second transmission gear ring 33 and the transmission box 2 to rotate.

[0035] During the elastic bloodless castration procedure on cattle and sheep, the surfaces of the rubber castration ring body 7 and the fixing hooks 4 are first disinfected. Then, the rubber castration ring body 7 is placed onto multiple fixing hooks 4, securing it within the arc-shaped anti-slip fixing grooves 5. Simultaneously, the friction particles 8 on the surface of the rubber castration ring body 7 increase the friction between it and the arc-shaped anti-slip fixing grooves 5, further improving the anti-slip properties of the rubber castration ring body 7 on the fixing hooks 4. Subsequently, a second drive mechanism drives the first transmission gear ring 11 to rotate, which in turn drives multiple first transmission gears 12 to rotate. The first transmission gears 12 then drive multiple transmission racks 3 to move, which in turn move multiple fixing hooks 4 outward from the center of the mounting plate 1, automatically opening the rubber castration ring body 7 to the desired position. Finally, the veterinarian manually grasps the scrotum of the cattle or sheep, completely squeezing the two testicles to the bottom of the scrotum to prevent the spermatic cord from getting stuck between the rubber ring and the scrotal wall. The expanded rubber ring is then slipped over the scrotum from the bottom upwards, pushing it to the base of the scrotum to ensure both testicles are completely beneath the ring. The second drive mechanism then rotates in the opposite direction, causing the main body 7 of the castration ring to retract and fix itself to the base of the scrotum. As the main body 7 retracts, the friction between it and the arc-shaped anti-slip fixing groove 5 decreases. The mounting plate 1 is then moved, disengaging the fixing hooks 4 from the main body 7. The main body 7 then tightens itself to hold the base of the scrotum. The entire process requires no manual expansion or pulling by the veterinarian, significantly reducing operational difficulty and physical exertion. This is particularly suitable for castration procedures in large numbers of cattle and sheep, facilitating the veterinarian's castration surgery. Simultaneously, multiple fixing hooks 4 expand radially outwards from the center, ensuring the main body 7 is evenly stressed circumferentially during expansion, preventing breakage or deformation due to excessive local tension, and improving the success rate of the surgery.

[0036] Example 2

[0037] Based on Example 1, please refer to Figures 1 to 7 As shown, a through groove 41 is provided through the transmission rack 3. One end of the transmission rack 3 is fixedly connected to a water spray head 42 that communicates with the through groove 41. The other end of the transmission rack 3 is fixedly connected to a connecting pipe 43 that communicates with the through groove 41. One end of the connecting pipe 43 is fixedly connected to a water supply mechanism that is connected to the mounting ring plate 1. The water supply mechanism is used to supply water to the connecting pipe 43.

[0038] The water supply mechanism includes a water tank 51 fixedly connected to the mounting ring plate 1. A water pump 52 is fixedly connected to one side of the water tank 51 via a pipe. A water supply pipe 53 is fixedly connected to the outlet end of the water pump 52. A water supply ring pipe 54 is fixedly connected to one end of the water supply pipe 53. A flexible hose 55 connected to a connecting pipe 43 is fixedly connected to the outer surface of the water supply ring pipe 54. An inlet pipe 61 is fixedly connected to the top of the water tank 51. A sealing plug 62 is threaded to the top end of the inlet pipe 61. Disinfectant is put into the water tank 51 through the inlet pipe 61.

[0039] A handle 71 is fixedly connected to one side of the mounting ring plate 1, and a storage battery 72 is fixedly connected to the mounting ring plate 1. The storage battery 72 provides power support for the first rotation drive component 21, the second rotation drive component 31, and the water pump 52, etc., to realize wireless and portable operation of the castration clamp. The handle 71 is convenient for gripping and operation.

[0040] When the expanded rubber castration ring body 7 is placed at the base of the scrotum, the disinfectant in the water tank 51 is pumped into the water supply pipe 53 by the water pump 52 and the pipe. Then, the water supply pipe 53 passes the disinfectant into the water supply ring pipe 54. The water supply ring pipe 54 supplies the disinfectant to the connecting pipe 43 through the hose 55. The disinfectant is then supplied into the spray head 42 through the through groove 41. At this time, the spray head 42 sprays the disinfectant onto the tight band. At the same time, the first drive mechanism drives the transmission box 2 to reciprocate. The transmission box 2 drives the transmission rack 3 and the spray head 42 to reciprocate. The spray head 42 automatically and evenly sprays the disinfectant onto the base of the tight band, achieving all-round, no-dead-angle disinfection of the tight band area, effectively reducing the risk of postoperative infection.

[0041] Working principle:

[0042] Through a multi-gear linkage and radial synchronous expansion mechanism, the rubber castration ring body 7 is automatically and evenly expanded and precisely retracted. In use, the rubber castration ring body 7 is first embedded in the arc-shaped anti-slip fixing groove 5 of each fixing hook 4, and the friction particles 8 on the inner wall of the rubber ring form a high-friction anti-slip positioning with the groove wall. Then, the second drive mechanism is activated, that is, the first rotation drive component 21 controlled by PLC programming drives the second transmission shaft 22 and the third transmission gear 23 to rotate. The third transmission gear 23 drives the first transmission gear ring 11 to rotate on a fixed axis. The first transmission gear ring 11 simultaneously meshes with and drives multiple circumferentially distributed first transmission gears 12. Each first transmission gear 12 drives the second transmission gear 14 to rotate synchronously through the first transmission shaft 13, thereby pushing each transmission rack 3 to move outward along the radial slide of the transmission box 2. Since the displacement of all transmission racks 3 is exactly the same, the multiple fixing hooks 4 fixedly connected to their inner ends expand radially outward synchronously from the center of the mounting plate 1, evenly expanding the rubber castration ring body 7 circumferentially to the preset diameter, completely avoiding the rubber ring from breaking or deforming due to uneven local force. After the veterinarian squeezes the two testicles in the scrotum of the cattle or sheep to the bottom and places the expanded rubber ring around the base of the scrotum, the second drive mechanism reverses, causing the fixing hooks 4 to retract radially. The rubber castration ring body 7 then contracts and tightly grips the base of the scrotum due to its high elasticity and recovery force. As the positive pressure between the inner wall of the rubber ring and the arc-shaped anti-slip fixing groove 5 is significantly reduced after the rubber ring retracts, the friction is reduced accordingly. The operator only needs to move the mounting plate 1 to allow the fixing hooks 4 to easily dislodge from the rubber ring, completing the bloodless castration. The entire process does not require manual pulling and expansion, greatly reducing the labor intensity of veterinarians. It is especially suitable for castration operations of cattle and sheep in batches, and the multi-point synchronous radial force application significantly improves the success rate of the operation and the safety of the operation.

[0043] After the rubber castration ring 7 is tightened around the base of the scrotum, the castration clamp further activates the built-in disinfectant spraying function to achieve immediate and comprehensive disinfection of the tightened wound. Specifically, after the water pump 52 is started, the disinfectant pre-filled in the water tank 51 through the inlet pipe 61 is pressurized and pumped into the water supply pipe 53. The disinfectant is distributed to each hose 55 through the annular water supply ring pipe 54, and then enters the through groove 41 opened along the length direction inside the transmission rack 3 through each connecting pipe 43. Finally, it is sprayed out from the spray head 42 fixed to the inner end of the transmission rack 3, directly acting on the tightened area at the base of the scrotum. At the same time, the second rotating drive component 31 in the first drive mechanism drives the drive gear 32 to rotate. The drive gear 32, through meshing with the second transmission gear ring 33, drives the entire transmission box 2 to reciprocate around its own axis at a set angle. Since the transmission rack 3 and the spray head 42 rotate synchronously with the transmission box 2, the spray head 42 performs a sweeping spray along the annular circumference of the base of the scrotum. Through the continuous liquid supply from pump 52 and the reciprocating oscillation of transmission box 2, the disinfectant is evenly and completely covered to the entire clamping area and surrounding tissue, achieving comprehensive and thorough chemical disinfection of the castration wound. This effectively kills pathogenic microorganisms and significantly reduces the risk of postoperative infection. Furthermore, the entire disinfection process is automated, requiring no additional veterinary intervention. This improves disinfection efficiency and ensures the uniformity of disinfection quality. Combined with the portable power supply of battery 72 and the ergonomic design of handle 71, this castration forceps can efficiently and reliably complete the entire surgical and postoperative treatment process even in complex environments such as pastures and animal pens.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
