[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a surgical suture needle that is easy to thread, comprising a needle tip portion 1, a needle body portion 2 is fixedly connected to the left side of the needle tip portion 1, the diameter of the needle tip portion 1 gradually becomes thicker toward the needle body portion 2, a first extension portion 3 is fixedly connected to the left side of the needle body portion 2, the first extension portion 3 extends to the left, the diameter gradually becomes thinner, the left side of the first extension portion 3 is bent downward and a dislocation anti-detachment hook 4 is extended to the needle body portion 2, a second extension portion 5 is fixedly connected to the left side of the needle body portion 2, the second extension portion 5 extends to the left, the diameter gradually becomes thinner, the left side of the second extension portion 5 is bent upward and a return hook 6 is extended to the needle body portion 2, the bottom of the dislocation anti-detachment hook 4 is in contact with the top of the return hook 6, the dislocation anti-detachment hook 4 is elastic, when the surgical suture is pulled to the right between the dislocation anti-detachment hook 4 and the return hook 6, the dislocation anti-detachment hook 4 will move slightly upward and generate a gap, so that the surgical suture passes through the gap between the dislocation anti-detachment hook 4 and the return hook 6.

[0029] Reference Figure 2-Figure 3The extension length of the dislocated anti-detachment hook 4 is longer than the return hook 6, and the right bottom end of the dislocated anti-detachment hook 4 is located below the contact surface between the return hook 6 and the dislocated anti-detachment hook 4. A threading hole 7 is formed between the first extension portion 3 and the second extension portion 5. When the surgical suture inside the threading hole 7 moves to the left, it will be blocked by the dislocated anti-detachment hook 4. When the surgical suture is located below the dislocated anti-detachment hook 4, it will directly slide into the return hook 6 and will not fall off. An anti-hook baffle 8 is fixedly connected to the inner wall of the right side of the threading hole 7, and the bottom end of the first extension portion 3 and the top end of the second extension portion 5 are both fixed to the outside of the anti-hook baffle 8. The anti-hook baffle 8 is U-shaped, and the left end of the anti-hook baffle 8 is located on the left side of the tip of the right end of the return hook 6, blocking the tip of the return hook 6 and the dislocated anti-detachment hook 4, reducing the possibility of the return hook 6 and the dislocated anti-detachment hook 4 piercing the skin again.

[0030] Reference Figure 1 A limiting groove 9 is provided on the front and rear sides of the needle body 2. The limiting groove 9 is located at the left third of the needle body 2, which is convenient for clamping with a needle holder and is relatively stable and not easy to fall off. The edge of the limiting groove 9 is set to a rounded corner to avoid collision between its edge and the needle holder and cause deformation of the needle body.

[0031] Working principle: When you want to thread the needle conveniently, straighten the surgical suture, and when you pull it to the right between the dislocated anti-detachment hook 4 and the return hook 6, the dislocated anti-detachment hook 4 will move slightly upward and create a gap, so that the surgical suture passes through the gap between the dislocated anti-detachment hook 4 and the return hook 6 and enters the threading hole 7. When performing surgical suture, the needle tip 1 passes through the skin and continues to puncture, the needle body 2 passes through the skin, and finally the first extension 3 and the second extension 5 and the anti-hook baffle 8 pass through the skin. The anti-hook baffle 8 blocks the return hook 6 and the tip of the dislocated anti-detachment hook 4, and cannot puncture the skin again, avoiding hooking the skin and causing secondary damage. When using a surgical suture needle, clamp the needle holder at the limiting groove 9 on the needle body 2 to make the needle holder clamp more firmly and avoid collision between its edge and the needle holder to cause deformation of the needle body.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
