Laparoscopic techniques have grown in popularity and wide application in pancreatic surgery, which often involves excision of lesions and anastomotic reconstruction. The operation difficulty of the laparoscopic pancreatic intestinal anastomosis reconstruction is higher than that of the open surgery, and a doctor with a main knife is often required to have a good laparoscopic suturing technology. The skill level and experience accumulation of the surgeon often are one of the key factors in determining the success or failure of anastomosis. However, for young doctors and inexperienced doctors, often due to inexperienced experience, it is difficult to control such surgical procedures, as clinically direct manipulation and accumulation of experience on the patient may increase the risk of surgery and complications. Traditional surgical procedures tend to build up experience through "patient teaching" of the handles on the operating table. In recent years, some simple laparoscopic models such as a bean clamping model, a high-low column training model, a steel wire walking ring model, a basic stitching template training model and other operation models are used for training basic space sense, positioning sense and simple stitching under the laparoscope, but the training models are too basic and lack of step-in growth; there are also some simple biliary-enteric anastomosis models, pancreatic-enteric anastomosis models, gastrointestinal anastomosis models, and the organ models often composed of these anastomosis models are simple and single, lack corresponding blood vessels and accurate spatial positioning; the practical fidelity of the training is lacking, the trainee still has difficulty in completing accurate and satisfactory anastomosis operation in the practical operation after the training is finished, and the conversion degree is lacking; meanwhile, as the anastomosis quality of the catheter to the mucosa anastomosis in the pancreatic anastomosis often needs to be evaluated by dismantling the anastomosis lines of pancreas parenchyma and intestinal tracts, the anastomosis quality of the catheter to the mucosa anastomosis is evaluated by naked eyes, objective evaluation indexes are lacking, and an evaluation system is lacking in objective fairness.
The lack of a practical mature model which is close to clinic at present can be applied to simulation training of the abdominal pancreatic intestinal anastomosis reconstruction operation; meanwhile, the lack of objective evaluation system of the suturing quality of the anastomotic stoma of the catheter of the model to the mucosa anastomosis is a difficulty in developing a model which is close to clinical practice, is easy to objectively evaluate and can simulate the pancreatic anastomosis reconstruction operation at the present stage.
