Abstract

The invention discloses a hydrophilic anti-fog nano coating for an endoscope and a coating. The hydrophilic anti-fog nano coating comprises the following components in parts by weight: 1-10 parts of plant polyphenol, 0.1-2 parts of metal ions, 0.1-0.5 part of biomass molecules, 10-20 parts of an auxiliary agent and 250 parts of a solvent, the coating is coated on the surface of a base material, and the required coating can be obtained after drying. Plant polyphenol and metal ions are combined to form a plant polyphenol-metal nano complex, the plant polyphenol-metal nano complex and biomass molecules form a hydrophilic nano film on the surface of the laparoscope, and the hydrophilicity of a lens surface interface is enhanced synergistically; the formula disclosed by the invention has high biocompatibility, does not cause clinical side reaction when being in contact with tissues, and can meet the requirements of clinical use.

Description

technical field [0001] The invention relates to the technical field of nano-membranes, in particular to a hydrophilic anti-fog nano coating and a coating for endoscopes. Background technique [0002] Minimally invasive surgery with the characteristics of small trauma and fast recovery has been deeply applied to all aspects of clinical practice, and is widely used in various minimally invasive surgeries in gynecology, general surgery, urology, and hepatobiliary surgery. Endoscopic technology is an important part of minimally invasive surgery. Endoscope is an advanced medical equipment integrating mechanical, electrical and optical technologies, and uses cold light source to provide illumination. In abdominal surgery, a laparoscopic lens with a camera system and light source is inserted into the abdominal cavity, and the images captured by the lens are displayed on the transfer monitor through the optical fiber by using endoscopic technology and image display technology.
