Background

The laparoscope for gastrointestinal surgery is an instrument with a miniature camera, like a gastroscope. Laparoscopic surgery is a procedure performed using a laparoscope and its associated instruments: the method comprises the steps of using a cold light source to provide illumination, inserting a laparoscope lens (the diameter is 3-10 mm) into the abdominal cavity, conducting an image shot by the laparoscope lens to a post-stage signal processing system through an optical fiber by using a digital camera technology, and displaying the image on a special monitor in real time. The physician then analyzes the patient's condition by displaying images of the patient's organ at different angles on the monitor screen and performs the surgery using special laparoscopic instruments.

When the existing laparoscope is initially arranged in a patient body, the lens of the laparoscope, namely the objective lens, can be fogged immediately due to the fact that the temperature difference between the outside of an operating room and the inside of the patient body is large instantaneously. This is because some of the water vapor is easily condensed on the relatively cold laparoscope lens, so that a layer of mist is formed on the laparoscope lens, which affects the definition of the view field viewed by the laparoscope lens, and further affects the examination or operation process.

In order to solve the problems, Chinese patent (patent publication No. CN211511740U) discloses a disposable anti-fog heating device for a laparoscopic lens, which comprises an outer shell, wherein a disposable inner shell is arranged in the outer shell, a groove is formed in the lower surface of the disposable inner shell, a contact piece is arranged in the groove, salient points are lapped on the lower surface of the contact piece and are arranged on the lower surface of the inner wall of the outer shell, the left end and the right end of the contact piece are respectively and electrically connected with two ends of a resistance wire, the resistance wire is arranged in the wall of the disposable inner shell in an S shape, the lower surface of a port of the disposable inner shell is bonded with the upper surface of the outer shell through viscose glue, and sealing paper is arranged on the upper surface of the disposable inner shell.
