The minimally invasive surgery is performed by using modern medical instruments such as a laparoscope, a thoracoscope and the like and related equipment, and has the characteristics of small wound, light pain, quick recovery and the like.

The laparoscope is a surgical instrument with a miniature camera, provides illumination through a cold light source, inserts a lens of the laparoscope into an abdominal cavity, transmits an image shot by the lens of the laparoscope to a signal processing system through an optical fiber by using a digital camera shooting technology, and displays the image on a display so as to assist a doctor to operate the surgical instrument, perform examination inside the abdominal cavity and the like. The laparoscope lens is generally in the shape of an inclined plane of 30 degrees, and in order to ensure smooth operation, ensure operation quality and reduce injury in the operation, a clear view is required, so that the laparoscope lens is required to be clear.

However, because the operating room environment is low relative to the body temperature of a human body, when the laparoscopic lens is inserted into the abdominal cavity, because the temperature difference between the inside and the outside of the abdominal cavity is large, part of water vapor is easy to condense after encountering a cold laparoscopic, and a layer of fog is formed on the lens, which affects the definition of the visual field on a display, and the clear surgical visual field is the key of the safety of the laparoscopic surgery, so the anti-fog treatment of the laparoscopic lens is of great importance.

At present, the lens antifogging is carried out clinically by adopting a normal saline heating method, an iodophor wiping method and a tissue wiping method, but some defects or shortcomings still exist, for example, the preparation time of the normal saline heating method is too long, and the hot normal saline needs to be replaced regularly, so that time and labor are wasted; the iodophor is colored liquid, and the iodophor is wiped by a dry cotton ball after being wiped so as to prevent the redundant iodophor from covering the lens and influencing the judgment of the color of organs in the abdominal cavity by an operator, and some patients are allergic to iodine and have limitations; tissue swabbing is often more blurred when more blood is present in the abdominal cavity.
