[0035] Working principle: When suturing the patient's wound, the surgical suture is installed on the clamping rod 3, and then one end of the closure device 1 provided with the clamping rod 3 is inserted into the patient's body, and then the two groups of card blocks 121 are pressed to shrink the first spring 126, so that the limit blocks 122 provided at both ends of the card block 121 are moved out from the lower limit hole 11, and the card block 121 is pushed to drive the movable seat 124 to move inside the handle 8 with the help of the connecting block 123. After moving to one end of the handle 8, the card block 121 is released, so that the first spring 126 pushes the two groups of card blocks 121, and then The limiting block 122 is made to clamp one end of the upper limit hole 10, so that one end of the clamping rod 3 is raised and fixed, and the connecting rod 2 is controlled to be folded or stretched, and the shape of the connecting rod 2 is changed to make the connecting rod 2 unfold into a flying wing shape, and then one end of the needle body 131 passes through the first channel 4 and the first through hole 6 opened on the connecting rod 2, and then the finger ring 1314 is pulled, so that the finger ring 1314 drives the inner rod 1311 to move inside the needle body 131, and then the limiting ring 1315 fixed on the inner rod 1311 moves, and through the cooperation between the limiting ring 1315 and one end of the needle body 131, the second spring 1316 The inner rod 1311 is compressed, thereby raising the position of the inner rod 1311, and the inner rod 1311 drives the third connecting ring 1313 set at the end to rise, and then one end of the connecting rod 139 installed on the third connecting ring 1313 rises, thereby changing the angle of the connecting rod 139, allowing the connecting rod 139 to push the recovery rod 135, so that one end of the recovery rod 135 rotates on the first connecting ring 133, and then the recovery rod 135 is moved out from the storage groove 132, so that the multiple groups of recovery rods 135 are unfolded, and then the needle body 131 is pulled a distance, so that the surgical suture falls on one group of recovery rods 13 5, when the finger ring 1314 is released, the second spring 1316 is reset to push the limit ring 1315 to move, thereby causing the inner rod 1311 to descend and complete the reset. When the needle body 131 is pulled out, the surgical suture falls into the bundle groove 136 and is fixed, and the recovery rod 135 returns to the storage groove 132. The recovery rod 135 will not cause secondary damage to the patient's wound. Similarly, one end of the needle body 131 is passed through the second channel 5 and the second through hole 7 opened on the connecting rod 2, and the other end of the surgical suture is passed through the patient's skin and taken out. By tying knots at both ends of the surgical suture, the surgical suture completes the wound.
