Article Abstract

Background: Visualization during scleral buckling is traditionally achieved via indirect ophthalmoscopy. Recent advances have utilized the surgical microscope and a 25 gauge cannula-based endoillumination system, also known as a Chandelier lighting system. This report details an improved approach using a guarded 25 or 27 gauge light pipe and the Ngenuity digital three dimensional platform.

Methods: A standard Alcon light pipe is modified with a silicone guard to expose only 5 mm of the tip of the light pipe. The guard is created from the silicone that is already opened to secure the ends of the encircling band most often employed sleeve (e.g. 70, 270). This guarded light pipe is then inserted into the cannula as an alternative to a Chandelier lighting system.

Results: This is a technical report of a surgical visualization technique using a three dimensional digital visualization platform with a modified handheld vitrectomy light pipe.

Conclusion: The utilization of a guarded light pipe for visualization during primary scleral buckling is a promising, effective, and efficient technique. The three dimensional digital display allows for better educational impact and surgical communication with trainees and ancillary members of the surgical team.

This study developed a variable-attitude multi-mirror-assisted digital image correlation method for realizing the simultaneous measurement of panoramic deformation inside and outside a tubular structure. The setup consists of a co-axial imaging system containing three variable-attitude optical mirrors and the necessary cold light source. The arrangement and attitude adjustment of the mirrors are the key to realizing panoramic imaging, thus enabling simultaneous imaging of the interior and exterior surfaces of a pipe.

Purpose: In vitrectomy for eyes with long axial lengths, trocar insertion distal to the limbus is beneficial for macular manipulation. We developed an intraocular endoscope-holding robot (OQrimo; Riverfield Inc, Tokyo, Japan), approved as a medical device in Japan. This study introduces a novel technique for trocar under direct visualization using OQrimo.

Cured-in-place pipe (CIPP) technology is a trenchless rehabilitation method for damaged pipelines in which a resin-saturated liner (often a fiber-reinforced type) is inserted into a host pipe and cured in situ, typically using a UV light beam or steam. This study investigates the influence of selected photoreactive diluents on the photopolymerization process of a styrene-free vinyl ester resin designed for the CIPP applications by evaluating the rheological properties, photopolymerization kinetics (photo-DSC), thermal characteristics (DSC), crosslinking density (gel content), and mechanical properties of thick (15 mm) UV-cured layers. The tested diluents included monofunctional (i.

The development of highly sensitive and reliable gas sensors is crucial for environmental monitoring, industrial safety, and healthcare applications. We report a facile block copolymer self-assembly approach for fabricating plasmonic Au nanoparticle-decorated WO three-dimensional cross-stacked nanowire arrays on microchips for enhanced gas sensing. The porous nanostructure of 3D WO NW framework, coupled with the catalytic and surface plasmon resonance properties of Au NPs, synergistically boosts the NO sensing performance.

In the field of triboelectric nanogenerators (TENGs), the application of a thin lubricant layer on the contact surface and its maintenance for long-term cycling remain important challenges for improving the mechanical-electrical stability of TENGs. Herein, a simple and innovative approach is proposed to solve this dilemma using commercial oil-absorbing sheets and oil infusion steps. In particular, a wind-driven nano-oil-barrier-based fluttering triboelectric nanogenerator (NF-TENG) is developed.
