Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a pressing type suture instrument in an embodiment of the present invention, which includes a left arm 10, a right arm 20, a shuttle swinging assembly 30, a surgical needle 40, a left thread 50, a right thread 60, a handle 90, a needle presser 70 and a spring 80, the left arm 10, the right arm 20 and the needle presser 70 are connected by a rotating shaft, a tip of the surgical needle 40 is provided with a small hole for the right thread 60 to pass through, the shuttle swinging assembly 30 is located at a front end of the left arm 10, the shuttle swinging assembly 30 includes a bobbin 31, a bobbin case 32 and a hook 33, the left thread 50 is led out through the shuttle swinging assembly 30, the right arm 20 is a hollow structure and a side wall is provided with an opening 21 for the surgical needle 40 to pass through, the needle presser 70 includes a holding end 71 and a pressing end 72, the pressing end 72 is sleeved inside the right arm 20, the left arm 10, the right arm 20 and the needle presser 70 are connected by the rotating shaft, the surgical needle 40 is vertically fixed at a side, spring 80 is fixed to the inner wall of right arm 20 and is located at the lower end of surgical needle 40. The left and right threads 50 and 60 are made of a material that can be absorbed by the human body. In a specific use, the medical staff moves the suturing device to the position where the patient needs to suture, presses the handle 90 to make the left arm 10 and the right arm 20 close to the nasal septum, and then presses the holding end 71, as shown in fig. 3, the pressing end 72 rotates around the rotating shaft, the surgical needle 40 is taken out from the cavity of the right arm 20, and the surgical needle 40 is taken out from the right arm 20, and simultaneously, the right thread 60 is taken through the nasal septum of the patient together by using the small hole on the surgical needle 40. The left thread 50 is interlaced with the right thread 60 by the shuttle assembly 30, as shown in fig. 4, the right thread 60 carried along with the surgical needle 40 is caught by the hook 33, the right thread 60 is interlaced with the left thread 50 drawn out by the shuttle assembly, then the hand-held end 71 is released, the pressing end 72 is restored to the original position by the spring 80, and then the stapler is moved to the next position to continue the suturing. The left thread 50 and the right thread 60 are made of materials which can be absorbed by human bodies, so that the process that the traditional knitting threads need to be removed is avoided, and the pain of a patient is relieved.
