Description

Technical Field

[0001] The utility model belongs to the technical field of veterinary surgical instruments, in particular to a veterinary suture needle. Background Art

[0002] A veterinarian is a doctor who prevents, diagnoses and treats diseases in animals. The responsibilities of a veterinarian include: conducting routine medical examinations on animals; conducting diagnostic tests, imaging, puncture and other diagnostic methods on animals; formulating targeted treatment plans for animals; observing changes in the animal's condition during the treatment of the animal, and promptly improving the treatment plan according to the disease treatment status; and promptly isolating and treating animals with infectious diseases and zoonoses. In the event that an animal is traumatized and the trauma is large, the skin is cracked, or a blood vessel is ruptured, the animal's wound needs to be sutured using a suture needle and suture thread.

[0003] The veterinary suture needle is an arc-shaped structure with a hole at the tail. When in use, the suture must be passed through the threading hole on the suture needle. However, the threading hole of the current suture needle is small, which is not convenient for the suture to be inserted. Moreover, when the suture is suturing the skin tissue, the suture will be pulled by the skin tissue, which will cause the suture to fall off the suture needle. The suture needs to be inserted into the suture needle again, which greatly prolongs the suture time and reduces the suture efficiency of the veterinarian. Utility Model Content

[0004] The utility model aims to provide a veterinary suture needle, which can reduce the situation that the suture thread falls off from the threading hole of the suture needle as much as possible during the suture process.

[0005] The veterinary suture needle comprises a suture needle body, a positioning head for fixing the suture thread feeder is arranged at the needle tail of the suture needle body, a threading hole for the suture thread to pass through is opened on the positioning head, a threaded hole connected to the threading hole is opened on the positioning head, a threaded rod threadedly matched with the threaded hole is fixed at the needle tail of the suture needle body, a thread entry port for the suture thread to pass into the threading hole is opened on the positioning head corresponding to the threading hole, an extrusion block for compressing the suture thread is arranged in the threading hole, and the threaded rod is connected to the extrusion block.

[0006] Furthermore, a limiting groove is provided on the inner wall of the threading hole.

[0007] Furthermore, the extrusion surface of the extrusion block is an arc-shaped structure.

[0008] Furthermore, a blocking piece is provided at the line inlet.

[0009] Furthermore, the edge of the line inlet is polished and rounded to form a chamfer.

[0010] Furthermore, the extrusion block is made of silicone material.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model moves the suture thread into the threading hole through the thread inlet, so that the suture thread is connected with the positioning head, and the positioning head is rotated to be threadedly connected with the threaded rod at the needle tail of the suture needle body through the threaded hole, and the extrusion block fixed at the bottom of the threaded rod gradually approaches the suture thread located in the threading hole until it is pressed tightly against the threading hole, thereby reducing the phenomenon of the suture thread falling off from the threading hole as much as possible, and improving the suturing efficiency of veterinary medicine.

[0016] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0017] Example

[0018] A veterinary suture needle as described in this embodiment, Figure 1 and Figure 2As shown, it includes a suture needle body 1, a positioning head 2 for fixing the suture thread at the needle tail of the suture needle body 1, a threading hole 7 for the suture thread to pass through is opened on the positioning head 2, a threaded hole connected to the threading hole 7 is opened on the positioning head 2, a threaded rod 8 threadedly matched with the threaded hole is fixed at the needle tail of the suture needle body 1, a thread entry port 3 for the suture thread to pass into the threading hole 7 is opened on the positioning head 2 corresponding to the threading hole 7, a squeezing block 6 for pressing the suture thread is arranged in the threading hole 7, and the threaded rod 8 is connected to the squeezing block 6. The suture needle body 1 includes a needle body, a needle tip and a needle tail. The suture needle body 1 is arc-shaped as a whole, and the threaded rod 8 is adhered to the needle tail of the suture needle body 1. The needle tail of the suture needle body 1 is flat, the top of the positioning head 2 that contacts the needle tail is also flat, and the bottom of the positioning head 2 is polished The locating head 2 is provided with a threading hole 7 which is connected to the front and back, and a threaded hole which is connected to the threading hole 7 is provided on the top of the locating head 2. The threaded rod 8 is threadedly matched with the threaded hole, so that the locating head 2 is fixed to the needle tail of the suture needle body 1. The locating head 2 at the threading hole 7 is provided with a thread inlet 3, so that the suture thread can be moved into the threading hole 7 through the thread inlet 3, so that the suture thread can be connected to the suture needle body 1. The threading hole 7 is provided with an extrusion block 6, which squeezes the suture thread and fixes it in the threading hole 7, which is more convenient and quick. The bottom of the threaded rod 8 is connected to the top of the extrusion block 6, so that the locating head 2 is connected to the suture needle body 1, so as to prevent the locating head 2 from falling off the suture needle body 1.

[0019] like Figure 1 and Figure 2 As shown, a limiting groove 5 is provided on the inner wall of the threading hole 7, and a limiting groove 5 is provided on the bottom of the threading hole 7. After the suture moves from the thread inlet 3 to the threading hole 7, it is moved into the limiting groove 5, and the suture is stuck in the limiting groove 5. When the threaded rod 8 drives the extrusion block 6 to approach the bottom of the threading hole 7, the extrusion block 6 presses the suture stuck in the limiting groove 5, further enhancing the stability of the suture in the threading hole 7, avoiding the suture from falling off the suture needle body 1 when the veterinarian sutures the wound, and better suturing the wound; the extrusion surface of the extrusion block 6 is an arc-shaped structure, the bottom of the extrusion block 6 is the extrusion surface, and the inner wall of the threading hole 7 is an arc-shaped structure. When the bottom of the extrusion block 6 contacts the inner wall of the threading hole 7, it can better contact with the inner wall of the threading hole 7, and better extrude and fix the suture, and the extrusion block 6 is made of silicone material, which is soft and elastic. The silicone can adapt to the shape of the suture and fit the surface of the suture closely, so that it is not easy to fall off or loosen;

[0020] like Figure 1 and Figure 2As shown, a blocking sheet 4 is provided at the wire inlet 3, and the blocking sheet 4 is adhered to the wire inlet 3, and an arc-shaped channel is formed between the blocking sheet 4 and the wire inlet 3. It is difficult for the suture thread to form an arc that matches the channel between the blocking sheet 4 and the wire inlet 3 inside the threading hole 7. Therefore, when the suture needle performs a back-needle operation, the suture thread will not slide out of the threading hole 7 through the wire inlet 3, thereby blocking the suture thread;

[0021] like Figure 1 and Figure 2 As shown, the edge of the wire inlet 3 is polished and rounded to be chamfered. After the edge of the wire inlet 3 is polished and rounded, during the suturing process, the edge of the wire inlet 3 can be prevented from being too sharp and protruding to scratch the animal, and the veterinarian can be prevented from being accidentally scratched;

[0022] In actual use, the suture is moved from the thread inlet 3 to the threading hole 7, so that the suture can be easily and quickly passed through the threading hole 7, and then the positioning head 2 is rotated to make its threaded hole threadably matched with the threaded rod 8 at the needle tail of the suture needle body 1, and the top of the positioning head 2 is constantly close to the needle tail of the suture needle body 1, thereby prompting the threaded rod 8 to drive the extrusion block 6 located at the threading hole 7 to gradually approach the suture, until the suture is pressed tightly against the threading hole 7, and the suture is fixed in the threading hole 7, so as to prevent it from falling off from the threading hole 7 during the suturing process, thereby improving the efficiency of veterinary suture.
