Laparoscopic Surgical Procedures Clinical Trial
Official title:
Nano-Ceramic Coating for Laparoscope Lens: a Cheap Magical Solution for Lens Fogging and Smearing
The investigator tests the effectiveness of nano-ceramic coating when applied (painted) on laparoscope lens to protect it from fogging or smearing during laparoscopic operations
A Ceramic Coating is a liquid polymer that is applied by hand to surfaces to make them
resistant to scratching, staining, rust or oxidation, as well as "hydrophilic", meaning that
water or mud doesn't stick to them and so, they become much easier to clean. It was publicly
commercialized in recent years for use on automobiles to preserve their gloss, protect their
paint, preserve the clarity of their wind shields and headlights so as to provide better
lighting and vision.
On the other hand, lens fogging and other vision-obstructing events during laparoscopic or
endoscopic operations(e.g. being smeared by blood or other body fluids during operation, or
having a piece of loose tissue stick to its surface that require manual removal and wiping)
have been an ever-lasting concern for operators ever since the advent of the respective
devices. Many techniques and methods have developed, tested and compared regarding their
effectiveness in protecting the lens from such events and preserving vision clear and
uninterrupted during operations. Examples of such methods are (scope warmers, FREDTM,
ResoclearTM, chlorhexidine, betadine and immersion in heated saline.
In this study the investigator seeks to apply the idea of nano-ceramic coating as a new
technique for achieving that goal. to the investigator's best knowledge, this idea was never
conceived or tested in the field before.
