Description

Technical Field

[0001] This utility model belongs to the technical field of veterinary insemination devices, specifically relating to a veterinary insemination tube ejector. Background Technology

[0002] Veterinary insemination devices are medical devices specifically designed for artificial insemination of animals. They play an important role in animal husbandry and pet breeding by delivering semen into the reproductive tract of female animals to achieve reproductive purposes.

[0003] The widely used push-type insemination device involves attaching the insemination tube to the head of the insemination sheath, and then using an insemination tube pusher to advance the tube into the animal's body to complete the procedure. Due to its simple, durable, and low-cost structure, it is widely used on farms. However, common insemination tube pushers simply involve placing the insemination sheath over the pusher without securing the sheath itself. This requires two hands from the operator: one hand to hold the sheath in place while the other presses the pusher. In practice, animals often have poor obedience, resulting in a low success rate of insemination tube insertion. Therefore, securing the insemination sheath to the pusher, allowing for one-handed operation, would significantly improve the success rate of insertion.

[0004] For the reasons mentioned above, this invention aims to provide a veterinary vas deferens ejector. Utility Model Content

[0005] The purpose of this invention is to provide a veterinary vas deferens ejector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A veterinary vas deferens ejector includes an outer tube and an inner needle tube, the inner needle tube penetrating the outer tube; the outer tube includes a sheath and a sheath handle, the sheath handle including a base and a cover plate, the cover plate being fastened to the front end of the base;

[0008] The inside of the cannula handle is provided with a cannula fixing groove, an insemination sleeve fixing groove and a clip fixing groove from back to front. The cover plate is provided with an insemination sleeve through hole one, the diameter of which is equal to the inner diameter of the insemination sleeve fixing groove. The cannula is inserted into the cannula fixing groove for fixing, and the cannula passes through the insemination sleeve fixing groove, the clip fixing groove and the insemination sleeve through hole one in sequence.

[0009] The clamp fixing groove is provided with a return spring and an L-shaped clamp. The return spring is located at the rear side of the L-shaped clamp, and the rear part of the L-shaped clamp abuts against the front part of the return spring. The side wall of the clamp fixing groove is provided with a clamp pre-drilled hole, through which the L-shaped clamp passes. The L-shaped clamp is provided with a second insemination sleeve through-hole, through which the sleeve passes.

[0010] The inner needle tube includes a long needle and a push-pull handle. The long needle is inserted into the cannula, and the push-pull handle remains outside the rear end of the cannula handle.

[0011] Preferably, when the push-pull handle abuts against the sleeve handle, the front end of the inner needle tube extends out of the front end of the sleeve.

[0012] Preferably, the diameter of the second perforation of the insemination sleeve is larger than the diameter of the first perforation of the insemination sleeve.

[0013] Preferably, a limiting ring is provided at the rear end of the sleeve handle, and correspondingly, a limiting protrusion is provided on the long needle head.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The present invention provides a veterinary insemination tube ejector, which has an L-shaped clip in the cannula handle. After the insemination tube is inserted into the cannula handle, the L-shaped clip can clamp the insemination tube and fix the insemination tube on the ejector.

[0016] (2) The present invention provides a veterinary vas deferens ejector with a limiting ring at the rear end of the cannula handle and a limiting protrusion on the long needle head. This design can effectively prevent the inner needle tube from sliding out of the outer cannula and enhance the integrity of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] A veterinary vas deferens ejector includes an outer tube 1 and an inner needle tube 2, with the inner needle tube 2 penetrating the outer tube 1. The outer tube 1 includes a sheath 3 and a sheath handle 4. The inner needle tube 2 includes a long needle 5 and a push-pull handle 6. The long needle 5 is inserted into the sheath 3, and the push-pull handle 6 remains outside the rear end of the sheath handle 4. When the push-pull handle 6 abuts against the sheath handle 4, the front end of the inner needle tube 2 extends beyond the front end of the sheath 3.

[0023] The sleeve handle 4 includes a base 7 and a cover plate 8, with the cover plate 8 fastened to the front end of the base 7. Inside the sleeve handle 4, from back to front, there are sequentially arranged sleeve fixing groove 9, insemination sleeve fixing groove 10, and clamp fixing groove 11. Simultaneously, the cover plate 8 has an insemination sleeve through hole 12. The sleeve 3 is inserted into the sleeve fixing groove 9 for fixation, and then passes through the insemination sleeve fixing groove 10, clamp fixing groove 11, and insemination sleeve through hole 12. To facilitate the passage of the insemination sleeve 13, the diameter of the insemination sleeve through hole 12 is equal to the inner diameter of the insemination sleeve fixing groove 10 and the same as the outer diameter of the insemination sleeve 13. Inside the clamp fixing groove 11, from back to front, there are mutually abutting return springs 14 and L-shaped clamps 15. A clamp pre-drilled hole 16 is provided on the side wall of the clamp fixing groove 11, through which the L-shaped clamp 15 passes. Under the action of the return spring 14, the L-shaped clamp 15 tilts upwards. The L-shaped clip 15 has a second insemination sleeve perforation 17, through which the sleeve 3 passes. To ensure the L-shaped clip 15 is effective, the diameter of the second insemination sleeve perforation 17 is larger than the diameter of the first insemination sleeve perforation 12. To prevent the inner needle tube 2 from slipping out of the outer sleeve 1, a limiting ring 18 is provided at the rear end of the sleeve handle 4; correspondingly, a limiting protrusion 19 is provided on the long needle tip 5.

[0024] During use, the operator takes a vas deferens tube 20, which is inserted into the head of the vas deferens sleeve 13. The operator presses the L-shaped clip 15 and slides the vas deferens sleeve 20 onto the cannula 3. The vas deferens sleeve 13 passes sequentially through the first vas deferens sleeve perforation 12 and the second vas deferens sleeve perforation 17 until it reaches the fixing groove of the vas deferens sleeve 13. The operator releases the L-shaped clip 15, and the return spring 14 pushes the L-shaped clip 15 forward, clamping the vas deferens sleeve 13. At this time, the L-shaped clip 15 appears to spring up on the outside of the cannula handle 4. The vas deferens tube 20 is now installed, and the operator can push the inner needle tube 2 to eject the vas deferens tube 20.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
