Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pressure needle mold for connecting medical suture needles. Background Technology

[0002] There are various methods and devices known for attaching needles to sutures. A commonly known method involves inserting the free end of the suture into the needle's end tube, then pressing it from two opposite directions on the outer surface of the needle end tube using a needle presser, followed by a second pressing by rotating it 90 degrees. The connection strength is ensured by the friction between the inner wall of the needle hole and the surface of the suture after pressing. However, because the inner diameter of the needle and the outer diameter of the suture can fluctuate, the friction can also vary, resulting in unstable needle-suture connection strength. In extreme cases, the needle and suture may come loose even before the suture is used after opening the packaging. If this happens during surgery, it can further disrupt the surgical process. Utility Model Content

[0003] The purpose of this invention is to provide a pressure mold for connecting medical suture needles, so as to solve the drawbacks of the existing technology, such as time-consuming double compression and unstable needle-thread connection strength.

[0004] To solve the above problems, the present invention provides a medical suture needle connection pressure needle mold, including a first mold base and a second mold base arranged opposite to each other. The first mold base has a first pressure needle end, and the second mold base has a second pressure needle end. The first pressure needle end is provided with a first needle insertion groove, and the second pressure needle end is provided with a second needle insertion groove. The first needle insertion groove and the second needle insertion groove are arranged opposite to each other and are both semi-circular. Their diameter is equal to the outer diameter of the suture needle tail tube, and their length is equal to the length of the suture needle tail tube. A first pressure needle protrusion is provided on the inner side of the first needle insertion groove, and the first pressure needle protrusion is located at the bottom of the groove. Two second pressure needle protrusions are provided on the inner side of the second needle insertion groove, forming an equilateral triangle with the first pressure needle protrusion, and located on the vertical plane of the needle insertion groove.

[0005] In some preferred embodiments, there are two first pressure needle protrusions and two second pressure needle protrusions, arranged side by side along the axial direction of the needle groove.

[0006] The beneficial effects of this utility model's medical suture needle-thread connection pressure mold are as follows: When the tail tube containing the suture enters between the first and second needle insertion slots, the pressure mold is activated. Since the diameter of the hole formed between the first and second needle insertion slots of the first mold base is equal to the outer diameter of the suture needle tail tube, the first and second pressure protrusions of the first and second mold bases cause localized concave deformation of the suture needle tail tube, compressing the suture and partially pressing it into the suture. This anchors the suture from three different directions. The needle-thread connection strength mainly relies on the tension of the thread, thus ensuring that the suture will not fall off, and that other parts of the suture needle tail tube will not deform. Because it is a one-time molding process, production efficiency is doubled. Attached Figure Description

[0008] Figure 2 Is with Figure 1 A schematic diagram of the compatible second mold base structure. Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] like Figure 1 , Figure 2 As shown, the medical suture needle connection pressure needle mold includes a first mold base 1 and a second mold base 2. The first mold base 1 has a first pressure needle end 11, and the second mold base 2 has a second pressure needle end 21. The first pressure needle end 11 is provided with a first needle insertion groove 12, and the second pressure needle end 21 is provided with a second needle insertion groove 22. The first needle insertion groove 12 and the second needle insertion groove 22 are arranged opposite to each other and are both semi-circular. Their diameter is equal to the outer diameter of the suture needle tail tube, and their length is equal to the length of the suture needle tail tube. A first pressure needle protrusion 13 is provided on the inner side of the first needle insertion groove 12. The first pressure needle protrusion 13 is located at the bottom of the groove. Two second pressure needle protrusions 23 are provided on the inner side of the second needle insertion groove 22, which form an equilateral triangle with the first pressure needle protrusion 13 and are located on the vertical plane of the needle insertion groove.

[0011] There are two first pressing needle protrusions 13 and two second pressing needle protrusions 23, which are arranged side by side along the axial direction of the needle groove.
