What changed

USPTO granted patent US12605220B2 for a robotic surgical tool with internal cleaning improvements. The patent describes a drive housing divided into upper and lower portions by a plate, with an injection port and diverter to direct cleaning fluid. The technology applies to robotic surgical instruments requiring internal flushing during reprocessing.

For manufacturers of robotic surgical systems, this patent establishes IP protection for a specific cleaning-fluid delivery mechanism using a diverter and ramp design within the drive housing. Competitors developing similar reprocessing systems may need to design around this claims set.
