According to experts, it is a device with a miniature camera. Laparoscopic surgery is an operation that uses a laparoscope and its related equipment: cold light source is used to provide illumination, a laparoscope lens (3-10mm in diameter) is inserted into the abdominal cavity, and digital camera technology is used to make the image captured by the laparoscope lens pass through the light guide The fiber is transmitted to the downstream signal processing system and displayed on the dedicated monitor in real time. Then the doctor analyzes and judges the patient's condition through the images of the patient's organs from different angles displayed on the monitor screen, and uses special laparoscopic instruments to perform the operation. Laparoscopic surgery mostly uses 2-4 hole operation methods, one of which is opened on the human belly button to avoid leaving long strips of scars on the abdominal cavity of the patient. After recovery, only 1-3 0.5- holes are left in the abdominal cavity. A linear scar of 1 cm can be said to be a small wound and less painful operation, so some people call it a "keyhole" operation. The development of laparoscopic surgery has alleviated the pain of patients undergoing surgery, shortened the patient's recovery period, and relatively reduced the patient's expenditure. It is a surgical project that has developed rapidly in recent years.
