[0034] The tail end has a threading structure, which includes an inner wire hole 1 in a long hole structure; the side wall of the tail end has a clamping opening 2; the clamping opening 2 is used for the suture to pass through and enter the inner wire hole 1;
[0035] The inner wire hole 1 has a stress point 3, and the clamping opening 2 is away from the stress point 3 of the inner wire hole 1.
[0036] The threading structure has a diagonal hole channel 4 communicating with the clamping opening 2, and the diagonal hole channel 4 is oriented away from the pressure direction of the stress point 3 of the inner wire hole 1.
[0037] A first hooking resistance body 41 is arranged between the stress point 3 of the inner wire hole 1 and the diagonal hole channel 4, and the first hooking resistance body 41 is used for resisting the suture from directly entering the diagonal hole channel 4.
[0038] In this embodiment, the suture is hung into the clamping opening 2 of the tail end of the surgical needle, and the suture after entering the clamping opening 2 will enter the inner wire hole 1 completely along the guide of the diagonal hole channel 4, and the suture will be hung on the stress point 3 of the inner wire hole 1 during the suture operation.
[0039] Since the diagonal hole channel 4 is oriented away from the pressure direction of the stress point 3 of the inner wire hole 1, the suture will not directly slide into the diagonal hole channel 4 during the normal suture operation and then be taken out by the clamping channel.
[0040] During the suture process or the suture gap process, the suture will be in a certain degree of relaxation state, at which time the suture will be resisted by the first hooking resistance body 41 to avoid directly entering the diagonal hole channel 4.
