![]() 6 used a plasma etching method to form microstructures on glass, generating a superhydrophilic surface that could effectively prevent fogging and maintain visibility in a humid environment by inducing film-like condensation of water 7, 8. To address some of these problems, surface modification has been used to engineer the material design and chemical properties of the lens. In view of these issues, it is necessary to develop a novel endoscope lens that can maintain both a clear operating field of view and excellent anti-biofouling properties for accurate diagnosis and effective surgical procedures. However, the aforementioned methods raise concerns regarding possible tissue damage due to rubbing, inconvenience due to the increased size of the endoscope, and the risk of bacterial infection. Alternatively, a clear field of view is ensured by retracting the endoscope from the body, wiping it clean, and then re-inserting it 3– 5. Conventional methods for cleaning the lens include mechanically rubbing the lens against adjacent tissue or introducing additional channels for suction and irrigation 2. Although a clear operating field of view is highly important in these applications, visibility can be lost because the endoscope lens is prone to biofouling and fogging due to adsorption of body fluids and high humidity. ![]() ![]() In addition, endoscopy is used both for diagnostic and therapeutic purposes as the inserted endoscope can visualize, collect biopsy, or remove soft tissue lesions from inside the body. Over the past decade, robotic or laparoscopic surgery has been widely adopted in preference to open surgery due to patient benefits such as reduced risk of infection, faster recovery, and short hospitalization 1. We believe that endoscopic lenses with the LIDENS offer excellent benefits to endoscopic surgery by securing clear visibility for stable operation. This excellent liquid repellency was also shown to be maintained during blood dipping, spraying, and droplet condensation experiments. ![]() This provides the lens with high transparency (> 70%) along with superior and long-lasting repellency towards various liquids. The LIDENS lens was chemically modified with a fluorinated self-assembled monolayer (F-SAM) followed by infusion of medical-grade perfluorocarbon lubricants. This directly engraved nano/microstructure provides LIDENS lenses with superior mechanical robustness compared to lenses with conventional particle-based coatings, enabling the maintenance of clear visibility throughout typical procedures. This structure was directly engraved onto the lens via line-by-line ablation with a femtosecond laser. Herein, a mechanically robust anti-fogging and anti-biofouling endoscope lens was developed by forming a lubricant-infused directly engraved nano-/micro-structured surface (LIDENS) on the lens. Conventional cleaning methods such as the use of an irrigation unit, anti-fogging surfactant, or particle-based porous coatings infused with lubricants have been used but proven insufficient to prevent loss of visibility. This was the second annual iChallenge competition, and it took place during the ForceCon conference.ĪETC hopes the contest will encourage airmen to come up with new, innovative ideas to train personnel, uncover those ideas and get them the resources needed to get those ideas into airmen’s hands.While a clear operating field during endoscopy is essential for accurate diagnosis and effective surgery, fogging or biofouling of the lens can cause loss of visibility during these procedures. military supremacy depends on our ability to rapidly innovate and be at the cutting edge of science and operational thought.” CJ Hale, chief of AETC’s rapid deployment office, said in the release. “The 2022 iChallenge winners embody our need to modernize our learning opportunities and techniques to train airmen and bridge our force development gaps and challenges,” Lt. The prize money is intended to be used as seed money to flesh out their concepts. The prize recipients will next try to further develop their ideas, track down more resources to make them a reality, and find other innovators they can collaborate with and learn from. Gissendaner is the wing’s operational medicine senior enlisted adviser. The VAPOR - or Validated Assessment Program for Operation Readiness - concept would streamline training efforts, lower costs and improve the readiness of medics, AETC said. Douglas Gissendanner of the 59th Medical Operations Squadron at Lackland’s 59th Medical Wing, seeks to improve the feedback process for medical personnel. The second runner-up idea, from Master Sgt.
