Background

At present, the minimally invasive concept of the surgical operation is deeply conscious and becomes one of the important options of the operation modes of the patients. Traditional laparoscopic surgery provides an operation space for an operation in an abdominal cavity by means of artificial pneumoperitoneum, but often affects the pneumoperitoneum state due to the application of an aspirator and the unclosed sleeve system or gas leakage when the vagina is surgically cut. Laparoscopic pneumoperitoneum procedures require the injection of carbon dioxide gas into the patient to create a pneumoperitoneum space in which instruments may be operated. However, pneumoperitoneum has many complications, such as the use of carbon dioxide to produce pneumoperitoneum, resulting in hypercapnia; pneumoperitoneum can cause air embolism or blood embolism, which is a fatal complication; the pneumoperitoneum can press the large blood vessels in the abdomen, such as inferior vena cava, mesenteric vein, and the like, reduce the blood volume of the heart and the blood supply of cardiac muscle, cause the blood pressure of the patient to be increased in the operation, cause the problems of the blood vessels of the heart and the lung, and is partially even fatal. Therefore, the conventional laparoscopic surgery is not suitable for patients having poor physical conditions or suffering from cardiovascular and cerebrovascular diseases, embolic diseases, and pulmonary insufficiency. Some studies have also found that pneumoperitoneum contributes to the growth, seeding and dissemination of tumor cells.

The current common gasless laparoscopic procedure is a suspended laparoscopic procedure. The suspended laparoscopic surgery is a surgical method of lifting the abdominal wall by an external auxiliary device, expanding the volume of the abdominal cavity, exposing the surgical field and performing surgical operation. The suspension type non-pneumoperitoneum laparoscopic surgery can avoid the complication of carbon dioxide gas embolism, is more safe than the pneumoperitoneum laparoscopic surgery, and enlarges the adaptation of the laparoscopic surgery. However, the current suspension laparoscope has the disadvantages that it is difficult to overcome. 1) Imbalance appearing in operative field: unlike the dome-shaped space formed by pneumoperitoneum, the space formed by the suspension device is irregular tower-shaped, and the upper abdomen is poorly exposed due to anatomical factors, so that the separation and the dissection of the colon hepatic flexure and the spleen flexure are difficult; 2) the operation is limited: the external subcutaneous steel needle and the suspension device thereof are used as obstacles to influence the operation space outside the abdominal wall of the operator while completing the suspension of the abdominal wall; 3) abdominal wall emphysema: tissue separation is caused by excessive lifting of the abdominal wall.
