For minimally invasive surgery, it is inevitable to create a passageway in the patient, and suturing of post-operative trauma to the patient is currently a major concern. Because no endoscope provides relevant visual field in the cavity when final wound is sutured after operation and suturing of the wound on the inner wall is difficult, the mode of only suturing the wound on the outer skin is mostly adopted. However, the intra-abdominal wound is not easy to monitor, and the infection and lesion of the wound and even hernia are easy to occur under the condition that the wound on the inner wall is not sutured.

At present, thread hooking devices on the market are all used as a fitting in a minimally invasive fascia suture device, and the fascia suture device needs to be inserted into a wound during operation so as to perform thread hooking suture by using the thread hooking device. Because the thread hooking device has no locking structure up and down in the fascia suture device, when the movable lock catch of the thread hooking device is pressed to hook the thread, the thread hooking device is easy to move up and down, the thread can not be hooked smoothly, and the suture failure is further caused. The operation process is delayed.
