The following will refer to the drawings Figures 1-4 , and combine the embodiments to specifically describe the present application. Embodiment 1

[0024] Embodiment 1 discloses a convenient operation oral suture needle, which comprises a needle body part 1, a clamping part 2 and a thread passing part 3, which are sequentially connected to constitute the whole oral suture needle. The needle body part 1 is similar to the existing suture needle, the whole adopts a circular arc design, and can be a round needle, an angle needle or a blunt needle design. The clamping part 2 is connected with the end of the needle body part 1 away from the needle tip, the whole also adopts the same circular arc design with the needle body part 1, and the cross section is a square round structure, that is, four flat surfaces are evenly arranged on the circular cross section, which is convenient for using forceps to clamp.

[0025] Reference is made to the drawings Figure 2 ​threading part 3 is connected to the end of the clamping part 2 away from the needle body part 1, and the whole is also designed with the same circular arc as the needle body part 1. A threading hole 301 is provided on the threading part 3, which is arranged along the length direction and can be in the shape of a long strip or a waist circle. Then a triangular guide slot 302 is provided on the side of the threading part 3 facing the center of the needle body part 1. The inner end of the guide slot 302 is provided with a thread insertion slit 303 connected to the side end of the threading hole 301. The gap of the thread insertion slit 303 is slightly smaller than the diameter of the suture thread. The steel raw material of the threading part 3 has a certain elasticity, so that when the suture thread is pulled into the thread insertion slit 303, the thread insertion slit 303 is slightly opened due to the elasticity of the threading part 3 itself, realizing the rapid entry of the suture thread into the threading hole 301.

[0026] Anti-drop protrusions 304 are provided on the inner walls of both sides of the end of the threading hole 301 away from the needle body part 1. Specifically, the anti-drop protrusions 304 are designed in the shape of an inclined trapezoid, and the two anti-drop protrusions 304 are mirror-symmetrically arranged on the two side walls of the threading hole 301, and the end portions between the two anti-drop protrusions 304 are designed to be in abutment. The abutment gap between the two anti-drop protrusions 304 is much smaller than the diameter of the suture thread. After the suture thread is introduced into the threading hole 301 through the thread insertion slit 303, the suture thread is then pulled towards the end away from the needle body part 1, and at the same time an action force is applied to the end of the threading part 3 away from the side of the center of the needle body part 1, so that the gap between the two anti-drop protrusions 304 is opened, allowing the suture thread to enter the tail end of the threading hole 301. After entering, the action applied to the threading part 3 is withdrawn, and then under the action of elastic restoring force, the two anti-drop protrusions 304 quickly abut together, avoiding the suture thread from slipping out of the abutment gap between them.

[0027] In addition, in order to avoid the situation of loose knot in the oral cavity using intermittent suture knot, it is necessary to improve the knotting method of the traditional suture rope. The embodiment 1 adopts the following Figure 4 The knotting method shown in the figure is marked as ① for the tail of the suture thread and ② for the head of the suture thread. The specific knotting steps are performed from left to right, so that this knotting method can form a self-locking lock knot. After the self-locking knot is formed, the suture thread at the head is directly pulled to make the self-locking knot reach the suture wound position like a cableway, and has the effect of locking the wound, plays a role in tightly pulling and suturing, and effectively avoids the situation of loose knot.
