Description

A haplopore peritoneoscope fixing device for exempting from pneumoperitoneum

Technical Field

The utility model relates to the technical field of single-port laparoscopic surgery, in particular to a pneumoperitoneum-free single-port laparoscopic fixing device.

Background

The single-port laparoscopic surgery is a common minimally invasive surgery mode of the abdominal surgery at present, the technology is mature, the surgery effect is better, the incision of the single-port laparoscopic surgery often enters the umbilical region, the umbilical region is perpendicular to the abdomen and forms an angle with the surgery region, the angle is not in the same horizontal line, the surgery visual field exposure and the surgery operation are seriously influenced, and the incision retractor is inclined due to the soft structure of the abdominal wall, so that the surgery difficulty is further increased;

and utilizes CO relative to conventional laparoscopic surgery₂Pneumoperitoneum technique to create surgical operating space, CO₂Pneumoperitoneum technique requires CO during surgery₂Continuous constant-pressure perfusion is needed, certain hidden dangers are brought to the operation safety of a patient, gas embolism, high carbon and subcutaneous emphysema type laparoscope pneumoperitoneum related complications are endless, particularly, a breathing system, a circulatory system and a pregnant fetus are affected badly, and surgical instruments are mutually angled, so that gynecology and general surgeons are deeply puzzled;

meanwhile, in the laparoscopic surgery process, the abdominal wall suspension pulling force of the pneumoperitoneum-free technology can cause the abdominal walls at two sides to be gathered towards the middle, and the extruded intestinal canal is concentrated towards the middle, so that the surgery space is reduced and narrowed, and the suspension device also occupies a certain position to block the movement of surgical instruments, so that the main defects of insufficient exposure of the surgery space and inconvenient operation are the defects of the surgery space and the surgical instruments;
