Description

Technical Field

[0001] The utility model relates to a suture needle, in particular to an easy-lead type suture needle. Background Art

[0002] Sewing needles are common household sewing tools, mostly used for modifying, sewing and repairing clothing.

[0003] When using a sewing needle, it is necessary to use the thread together. When threading the needle, the thread head needs to be passed into the through hole on the threading part of the sewing needle away from the needle head. Since the size of the sewing needle is relatively small, the through hole on the threading part is also smaller, so there are many inconveniences when threading the needle, especially for middle-aged and elderly people with blurred vision.

[0004] Prior art, such as the Chinese utility model patent with publication number CN209059305U and name “Easy-threading Suture Needle”, discloses the following technical solution: “Easy-threading suture needle, comprising a needle body; a needle tail connector is arranged at the tail end of the needle body, and also comprises a needle body sleeve that can be fixedly sleeved on the tail of the needle body, a sleeve connector is arranged on the needle body sleeve, and the sleeve connector and the needle tail connector are in contact and cooperate with each other to form a closed needle eye, and the suture thread enters the needle eye through the joint of the sleeve connector and the needle tail connector. The needle body and the needle body sleeve adopt a split structure, and a needle body sleeve positioning structure adapted to the needle body sleeve is arranged at the tail of the needle body. The needle body sleeve is sleeved on the needle body and can be fixed on the needle body through the needle body sleeve positioning structure”.

[0005] The above scheme forms a closed needle eye by putting the needle body sleeve on the needle body, and the sleeve connector contacts and cooperates with the needle tail connector; pulling the suture thread can make the suture thread quickly enter the needle eye, realizing the need for fast threading, and after the suture thread passes through the needle tail connector and the sleeve connector, the sleeve connector and the needle tail connector resume the contact state, which will not affect the normal suturing process.

[0006] Although the above scheme can form a needle eye through the deformation and cooperation of the first needle tail connecting strip and the sleeve body positioning contact body, thus simplifying the threading operation, the deformation structure of the first needle tail connecting strip and the sleeve body positioning contact body is prone to deformation under the pulling force of the thread during use, causing the thread to escape from the needle eye. In addition, both the first needle tail connecting strip and the sleeve body positioning contact body are structures with large deformation, which are easily damaged during actual use.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] refer to Figures 1 to 4A thread-easy suture needle comprises a needle body 1 and a threading portion 2. The threading portion 2 is located at an end of the needle body 1 away from the needle tip. The needle tip is used for puncturing, and the threading portion 2 is used for threading a thread 4, so that the thread 4 is connected to the needle body 1.

[0030] The threading part 2 includes a first elastic guide part 21, a second elastic guide part 22, a first elastic stop part 25, and a second elastic stop part 26. The first elastic guide part 21 is connected to the needle body 1 through a first connecting part 23, and the first connecting part 23 is used to connect the first elastic guide part 21 and the needle body 1. The second elastic guide part 22 is connected to the needle body 1 through a second connecting part 24, and the second connecting part 24 is used to connect the second elastic guide part 22 and the needle body 1.

[0031] The first elastic guide portion 21 and the second elastic guide portion 22 are arranged opposite to each other; that is, the first elastic guide portion 21 and the second elastic guide portion 22 are arranged in a left-right symmetrical shape relative to the central axis of the needle body 1 .

[0032] The first elastic stop portion 25 is connected to the end of the first elastic guide portion 21, and the second elastic stop portion 26 is connected to the end of the second elastic guide portion 22; the first elastic stop portion 25 and the second elastic stop portion 26 are both used to block the wire 4 in the threading portion 2 to prevent the wire 4 from escaping from the threading portion 2.

[0033] The oblique stop structure 3 is also included, and the oblique stop structure 3 is located on the surface opposite to the first elastic guide portion 21 and the second elastic guide portion 22. The oblique stop structure 3 is used to block the wire 4 in the threading portion 2 to prevent the wire 4 from escaping from the threading portion 2 through the gap between the first elastic stop portion 25 and the second elastic stop portion 26.

[0034] The first elastic guide portion 21 is folded relative to the first connection portion 23 toward the axis of the needle body 1 ; the second elastic guide portion 22 is folded relative to the second connection portion 24 toward the axis of the needle body 1 ; an M-shaped structure is formed at the top of the needle body 1 .

[0035] The end of the first elastic guide part 21 abuts against the end of the second elastic guide part 22; and the first elastic guide part 21 and the second elastic guide part 22 form a V-shaped structure, and the guide area between the first elastic guide part 21 and the second elastic guide part 22 is a guide area. The V-shaped structure is conducive to guiding the wire 4, thereby facilitating the lead-in.

[0036] The first elastic guide portion 21 and the first connecting portion 23 are integrally formed to form a U-shaped structure, which can be elastically deformed; the second elastic guide portion 22 and the second connecting portion 24 are integrally formed to form a U-shaped structure, which can be elastically deformed.

[0037] The first elastic stop portion 25 extends from the end of the first elastic guide portion 21 toward the side wall of the first connecting portion 23 to achieve blocking of the wire 4; the second elastic stop portion 26 is set from the end of the second elastic guide portion 22 toward the side wall of the second connecting portion 24 to achieve blocking of the wire 4.

[0038] The first elastic stop portion 25 and the second elastic stop portion 26 are both arc-shaped; the end of the first elastic stop portion 25 abuts against the side wall of the first connecting portion 23 to achieve blocking of the line 4, and the end of the second elastic stop portion 26 abuts against the side wall of the second connecting portion 24 to achieve blocking of the line 4.

[0039] The oblique stop structure 3 includes an oblique stop protrusion 31 and an oblique groove 32; the oblique stop protrusion 31 and the oblique groove 32 are located in corresponding positions and a gap is left between them, and the gap is used for the wire 4 to pass through when leading the wire.

[0040] The oblique stop protrusion 31 is in a convex shape and has an oblique convex surface; the oblique groove 32 is in a groove shape and has an oblique groove surface. The oblique stop protrusion 31 in a convex shape can form a block for the gap between the first elastic stop portion 25 and the second elastic stop portion 26.

[0041] The convex surface corresponds to the slant groove surface and a gap is left between the two, and the gap is used for the wire 4 to pass through when the wire is led; the gap between the convex surface and the slant groove surface is obliquely connected to the gap between the first elastic guide part 21 and the second elastic guide part 22, and there is an angle between the two gaps. The angle can be an obtuse angle.

[0042] The oblique blocking protrusion 31 is located at the connection between the second elastic guide portion 22 and the second elastic stop portion 26, so as to prevent the wire 4 from escaping from the threading portion 2 through the gap between the first elastic stop portion 25 and the second elastic stop portion 26. The oblique groove 32 is located at the connection between the first elastic guide portion 21 and the first elastic stop portion 25, so as to prevent the wire 4 from escaping from the threading portion 2 through the gap between the first elastic stop portion 25 and the second elastic stop portion 26.

[0043] The specific application method of the utility model is:

[0044] When the thread 4 needs to be passed through the threading portion 2 on the needle body 1, the thread 4 is aligned so that the length direction of the needle body 1 is parallel to the extending opening direction of the eye of the threading portion 2, such as Figure 1 Shown posture.

[0045] Then, along Figure 1Pull the two ends of the wire 4 downward in the direction indicated by the middle arrow, and the wire 4 will expand the guide area between the first elastic guide part 21 and the second elastic guide part 22, that is, the first elastic guide part 21 and the second elastic guide part 22 will undergo outward elastic deformation; at the same time, the first elastic stop part 25 and the second elastic stop part 26 will undergo elastic deformation relative to the first elastic guide part 21 and the second elastic guide part 22 respectively; thereby, the wire 4 passes through the guide area between the first elastic guide part 21 and the second elastic guide part 22.

[0046] Then, the wire 4 reaches the bevel stop structure 3. Since the first elastic guide part 21 and the second elastic guide part 22 have been stretched open, the gap between the bevel stop protrusion 31 and the bevel groove 32 of the bevel stop structure 3 is enlarged. The wire 4 passes between the bevel stop protrusion 31 and the bevel groove 32, and finally enters into the needle eye on the threading part 2, completing the threading operation.

[0047] During use, the thread 4 will be blocked by any one of the first elastic stopper 25, the second elastic stopper 26 and the oblique stopper structure 3, so that the thread 4 will not escape from the eye of the threading part 2, ensuring the normal use of the suture needle.

[0048] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
