Embodiment 1

[0025] The suture needle of the present embodiment is sequentially connected by the needle point 2, the needle body 1, and the needle tail 3 to form a C-shaped curved body. The diameters from the needle tail 3 to the needle tip 2 tend to decrease gradually, and the diameter of the needle tip 2 end is the smallest. The diameter of the needle tail 3 is the largest. Wherein the end of the needle tail 3 is provided with a thread hole 6, and the thread hole 6 is connected with the suture thread 7.

[0026] The radial section at any position of the suture needle presents a quasi-hexagon, and each side of the quasi-hexagon is a curved side, and each side bends toward the center. The six sides of the quasi-hexagon have a pair of opposite sides a 5 with the same length, and the other four sides b 4 have the same length. The length of side a 5 is greater than the length of side b 4 . The side a 5 is arranged on the inner side and the outer side of the suture needle, and the side b 4 i...

Embodiment 2

[0028] The suture needle of the present invention is no different from the use of conventional round needles and angle needles in use. The needle holder of the suture needle is clamped in the area of ​​about 1 / 3 to 1 / 2 behind the needle body. It is perpendicular to the suture needle and assisted by tweezers. When entering and exiting the needle, keep the needle tip perpendicular to the mucous membrane to draw and align the wound. In this way, the mucosal puncture speed is faster, the trauma is less, the efficiency is higher, and the degree of fatigue is greatly reduced.

Abstract

The invention discloses a hexagonal-like suture needle for oral mucosa and application, and belongs to the field of medicine. The suture needle is characterized in that a needle tip part, a needle body and a needle tail part are sequentially connected to form a c-like bent main body, the diameter from the needle tail part to the needle tip part is gradually reduced, the diameter of the needle tip part is minimum, and the diameter of the needle tail part is maximum. The radial section of any position of the suture needle is hexagonal-like, each edge of the hexagonal-like shape is a curve edge, and each edge is bent towards the center. The constraint of the traditional angle needle and round needle concept is broken through, compared with an angle needle, the operation can be more minimally invasive, and the linear suture wound is easier to heal; compared with a round needle, the suture efficiency can be improved, the suture resistance can be reduced, and the fatigue of doctors can be relieved; and the suture needle is suitable for various oral mucosa, and a doctor does not need to replace the needle when using the suture needle.

Description

technical field [0001] The invention belongs to the medical field, and in particular relates to a hexagonal-shaped suture needle for oral mucosa and its application. Background technique [0002] Oral mucosa has its particularity compared to skin and other visceral mucosa or muscle tissue. There are many types of oral mucosa and each has its own characteristics: ①Masticatory mucosa: including gums and hard palate mucosa, which bear pressure and friction during chewing, are firmly attached and cannot move, and are relatively tough and brittle in texture; ②Coating mucosa: lip The mucous membranes of the cheeks, belly of the tongue, floor of the mouth, soft palate, etc., except for the masticatory mucosa and the mucosa of the back of the tongue, are softer than other parts, have glandular elasticity, are not easy to tear off, have a certain degree of mobility, and can relieve pulling force;③ Special mucous membrane: the mucous membrane of the back of the tongue, which has a ce...
