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.

Abstract
A robotic surgical tool that includes a plate inside of a drive housing. The drive housing is divided into an upper portion and lower portion by the plate. Extending from the drive housing is an elongate shaft. The robotic surgical tool also includes an injection port that passes a cleaning fluid into the drive housing. Inside the drive housing there is a diverter adjacent to the injection port. The diverter has a ramp which can direct fluid from the injection port to the upper portion of the drive housing.
