Researchers Submit Patent Application, "Surgical Laser Fiber Standoff Arrangement For Preventing Dust Particle Accumulation During A Laser Lithotripsy Procedure", for Approval (USPTO 20240164836).

A patent application has been submitted for a new surgical laser fiber standoff arrangement that aims to prevent dust particle accumulation during laser lithotripsy procedures. The invention involves using a standoff that creates space between the laser fiber and the target, preventing contact and potential fiber degradation. The application discusses different versions of the standoff, including a non-cylindrical design that doesn't trap dust particles and a modified cylindrical standoff with a flushing system. The invention addresses the challenges posed by continuous wave Thulium fiber lasers, which generate more heat and can degrade the fiber. The application also mentions previous improvements to the standoff sleeves and methods for laser lithotripsy procedures. This patent application describes an improved optical fiber arrangement for laser surgery applications, specifically for laser lithotripsy procedures. The invention aims to prevent dust accumulation in laser surgery systems that use standoff sleeves or protective tips. The standoff sleeves are modified to prevent dust accumulation by extending on one side of or partially around the fiber, including ports for flushing out dust particles, and using materials that resist heat. The invention also allows for precise positioning of sensors or detectors at the treatment site. The patent application provides detailed claims and additional information for those interested in further research. [Extracted from the article]
