Coordinated movement control of robotic surgical tools
Summary
USPTO published patent application US20260090855A1 by inventor Alexander Tarek Hassan for a robotic medical system enabling coordinated movements of robotic surgical tools through multiple ports while maintaining remote centers of motion. The system provides three control modes for managing camera and tool coordination during surgical procedures, with automatic movement capabilities to keep tools within camera field of view.
What changed
The patent application discloses a robotic medical system and methods for performing coordinated movements of robotic tools inserted within a patient through multiple separate ports. The system maintains remote centers of motion during coordinated movements. Three control modes are disclosed: (1) a first control mode where a first robotic tool (e.g., camera) is moved using a first controller and multiple robotic tools automatically move in coordinated movements with the first robotic tool; (2) a second control mode where a robotic camera is controlled using a first controller and multiple robotic tools automatically move in coordinated movements to stay within a field of view of the robotic camera; (3) a third control mode where multiple robotic tools are moved in automatic coordinated movements using a first controller and a robotic camera is controlled using a second controller.
This is a published patent application (Kind A1) for informational purposes. No immediate regulatory action or compliance requirements are imposed on medical device manufacturers or healthcare providers. Companies developing robotic surgical systems may wish to review this application to assess potential prior art implications for their own patent portfolios. The filing date is December 5, 2025, with application number 19410925.

Abstract
Provided is a robotic medical system and related methods for performing coordinated movements of robotic tools inserted within a patient through multiple separate ports and maintaining remote centers of motion during the coordinated movements. In a first control mode, a first robotic tool is moved (e.g., a camera) using a first controller and multiple robotic tools are automatically moved in coordinated movements with the first robotic tool. In a second control mode, a robotic camera is controlled using a first controller and multiple robotic tools are automatically moved in coordinated movements to stay within a field of view of the robotic camera. In a third control mode, multiple robotic tools are moved in automatic coordinated movements using a first controller and a robotic camera is controlled using a second controller.
