For patients with perforation of the digestive tract, the perforation suture is the most basic and reliable treatment means, and the surgical suture technology can realize full-layer alignment suture of the wall of the digestive tract, which is an important factor for tissue healing and preventing leakage after the operation of the digestive cavity. The traditional open gastrointestinal repair operation has large incision, long operation time, easy infection after operation and more complications, and seriously affects the postoperative rehabilitation of patients. In the continuous development and popularization process of minimally invasive technology, the laparoscopic technology is more and more mature, is widely applied to the treatment of digestive tract perforation, and has good clinical use effect.

However, the laparoscopic treatment for perforation of the digestive tract has the defects of high technical difficulty, complicated operation, long time and the like, so that a doctor with quite abundant experience of using the laparoscopic is required to operate, and the perforation is performed again in a short period due to improper suturing with little carelessness. The key points and the difficult points of perforation repair under a cavity mirror are as follows: the first difficulty is that when the needle is inserted under the endoscope, the needle insertion difficulty is high, the position is difficult to fix, the suture stitch is uneven, and the back wall of the stomach is possibly sutured or leakage is possibly caused mainly because of the very limited surgical instruments which can be placed under the endoscope, the objectively existing sheath torque of the needle holding forceps, synchronous coordination of the forceps head and the handle operation, the indefinite direction of the handle and the suture needle which are possibly caused by the indefinite perforation position and the like; the second difficulty is when laparoscopic knotting is performed. The doctor can basically master the second difficulty through proper training, and the first difficulty is difficult to overcome through exercise, so that the repairing effect of the perforation and the prognosis of the patient are greatly influenced, and the doctor is tired in long-term operation. Therefore, we provide a rapid suture needle device for perforation of the digestive tract under a laparoscope to solve the above problems.
