The pack must maintain its full integrity throughout the continuum to ensure sterility. Factors that adversely affect sterile barrier integrity are crushing, dropping, stacking, compression, tears, holes, ruptures of…

Demystifying Liquid vs Vaporized Hydrogen Peroxide in SPD
Hydrogen peroxide (H2O2) is a small and simple molecule with a formula close to water but having somewhat different properties. Across industries, H2O2 solutions are used in many ways. For instance, in textiles it is commonly used as a bleaching agent, while in the aerospace industry it is known as a rocket propellant. H2O2 comes…

Robotic surgery is not new. We are over a decade into it being standard practice for many procedures. The technology and hardware have developed, but the principle of attaching, using, and re-sterilizing bespoke instruments has not. When the first robotic programs were being set up in hospitals, the instruments were sterilized in a tray. It…
