[0001] The present application relates to the technical field of suture needles, and in particular to a fascia suspension suture needle. Background Art
[0002] In order to combat the aging of facial skin and fascia, a minimally invasive incision is made within the temporal hairline. A fascia suspension guide needle is used to pass the polyester braided thread under the scalp upward to the skull periosteum and downward to the edge of the hairline for composite fixation to achieve the effect of facial lifting.
[0003] In minimally invasive facial fascia suspension surgery, buried guide needles are usually used for suturing. Buried guide needles were originally used for suturing soft tissues such as muscle tissue or fascia lata ligaments. The needle tip is a round needle at one end and an angle needle at the other end. However, due to the thick and tough tissues in the scalp area, it is difficult to insert a buried guide needle with a round needle tip. Utility Model Content

[0010] Preferably, the needle body is arc-shaped, and the radius is 35mm-40mm.
[0011] By adopting the above technical solution, the needle body is strengthened and the size of the needle body is made appropriate, so that the needle body can be easily moved back and forth during surgery.
[0012] Preferably, the pressure planes of the two needle tips are at 90°.
[0013] Preferably, the needle body includes a needle nose and a needle body connected to opposite sides of the needle nose, the two needle tips are respectively connected to ends of the two needle bodies away from each other, the opposite sides of the needle nose are flattened, and a through hole for threading is opened on the needle nose.
[0014] By adopting the above technical solution, flattening the two sides of the needle nose facilitates the operation of the needle holder, and at the same time can reinforce the needle body on both sides, making it less likely for the needle body to deform or break during needle movement.
[0015] Preferably, the radial direction of the needle body is perpendicular to the plane where the needle nose is located.
[0016] Preferably, the cross-section of the needle body is circular, and the diameter of the needle body is 1.5 mm-3 mm.

[0027] The following is combined with Figure 1-3 This application is described in further detail.
[0028] The present application embodiment discloses a fascia suspension suture needle. Figure 1 and Figure 2 The fascia suspension suture needle includes a needle body 1, which is arc-shaped. The needle body 1 includes a needle nose 101 and a needle body 102. Two needle bodies 102 are provided. The two needle bodies 102 are integrally formed on opposite sides of the needle nose 101. The cross-section of the needle body 102 is circular. The opposite sides of the needle nose 101 are flattened. The cross-section of the needle nose 101 is elliptical. The needle nose 101 is provided with a through hole 3 for threading.
[0029] Reference Figure 1 and Figure 2 The ends of the two needle bodies 102 that are away from each other are integrally formed with needle tips 2, and the needle tips 2 are angle needles. Each needle tip 2 is provided with a pressing plane 21 on two opposite sides, and the end and side surfaces are sharpened, and the cross section of the needle tip 2 is a quadrilateral.
[0030] When in use, thread is passed through the through hole 3, the needle body 1 is operated with a needle holder, and the needle tip 2 of the needle body 1 is passed through the scalp tissue for needle suturing. Since the tip of the angle needle is relatively sharp and not easily deformed, it can be well applied to suturing thick and tough scalp tissues. Moreover, angle needles are used at both ends of the needle body 1, which is convenient for moving back and forth, providing convenience for the needle operation and greatly improving the smoothness of needle movement.
[0031] Reference Figure 2 and Figure 3 The curvature of the needle body 1 is 1 / 2 arc or 3 / 8 arc, and the radius is 35mm-40mm. Preferably, the curvature radius of the needle body 1 is 39mm. The curvature is suitable and easy to operate.
[0032] Reference Figure 2 and Figure 3 The horizontal distance between the two ends of the needle tips 2 that are away from each other is 70mm-75mm, and preferably, the horizontal distance between the two ends of the needle tips 2 that are away from each other is 72mm. The effective operation length for the scalp tissue is appropriate, and it is not easy to cause the possibility of poor surgical effect due to insufficient effective operation length of the needle.
[0033] Reference Figure 2 and Figure 3, the radial direction of the needle body 1 is perpendicular to the plane where the needle nose 101 is located, so that the radial direction of the needle body 1 is parallel to the axial direction of the through hole 3, the long diameter of the needle nose 101 is 9mm-10mm, the short diameter of the needle nose 101 is 2.5mm-3.5mm, and the thickness of the needle nose 101 is 1mm-1.5mm; preferably, the long diameter of the needle nose 101 is 9.5mm, the short diameter is 3mm, and the thickness is 1.25mm. Designing the needle nose 101 as a plane, on the one hand, helps to reinforce the needle body 102 on both sides, so that the needle is not easily deformed or broken during the needle movement; on the other hand, it is convenient for the needle holder to clamp the needle, which helps to improve the smoothness of the needle movement and provide convenience for the implementation of the operation. In other embodiments, the radial direction of the needle body 1 can be designed to be perpendicular to the axial direction of the through hole 3.
[0034] Reference Figure 1 and Figure 2 The cross-section of the through hole 3 is elliptical, the length direction of the through hole 3 is parallel to the length direction of the needle nose 101, and the through hole 3 is located at the center of the needle nose 101; the long diameter of the through hole 3 is 1.2mm-2mm, and the short diameter of the through hole 3 is 0.8mm-1.1mm. Preferably, the long diameter of the through hole 3 is 1.5mm, and the short diameter is 1mm, which is convenient for the passage of the suture.
[0035] Reference Figure 2 and Figure 3 The diameter of the needle body 102 is 1.5 mm to 3 mm, and preferably, the diameter of the needle body 102 is 2 mm. Compared with the original buried guide needle, the size of the needle is strengthened, so that when the needle is inserted into the thick and tough scalp, it is not easy to deform the needle or even break the needle in the scalp.
[0036] Reference Figure 2 and Figure 3 The pressure planes 21 of the two needle tips 2 are at 90°, which is convenient for the needle tips 2 to pass through; the length of the needle tip 2 is 3mm-4mm, preferably, the length of the needle tip 2 is 3.5mm; the angle of the pressure plane 21 of the needle tip 2 is 30°-33°, preferably, the angle of the pressure plane 21 of the needle tip 2 is 31.5°. By limiting the size of the needle tip 2, strengthening and thickening the needle tip 2, it is convenient for the needle to pass back and forth, not easy to deform, and the needle moves smoothly, which provides convenience for the implementation of the operation.
[0037] Reference Figure 2 ,The needle tip 2 and the needle body 1 are both made of 316L stainless steel, which has the advantages of high corrosion resistance, good high temperature strength and high hardness.
[0038] The implementation principle of the embodiment of the present application is as follows: when in use, the suture thread is inserted into the through hole 3, and the needle holder is used to pass the needle tip 2 of the needle body 1 through the scalp tissue for needle suturing. Since the two ends of the needle body 1 use angle needles, the tip is relatively sharp and not easy to deform, which makes it convenient to move the needle in the thick and tough scalp area, and improves the smoothness of the needle movement to a certain extent; at the same time, compared with the original buried guide needle, the present application redesigns the size of the needle body 1, greatly improves and strengthens the size of the needle, so that the needle is not easy to deform and break during the operation, and it is not easy to cause poor surgical results due to insufficient effective operating length of the needle, which provides convenience for the implementation of the operation.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
