Stryker has been granted a patent for a surgical system that utilizes a manipulator and controllers to define and execute a tool path for tissue removal. The system autonomously identifies and removes both initial and additional tissue portions based on acquired data from the surgical site.

Surgical system for automated tissue removal and tool path generation
The patent US12070288B2 describes a sophisticated surgical system designed to enhance the precision and efficiency of tissue removal during surgical procedures. Central to this system is a manipulator that supports and moves a surgical instrument, operated by one or more controllers. These controllers are tasked with obtaining data that defines the volume of tissue to be excised, facilitating the removal of initial tissue portions, and subsequently identifying additional tissue portions that require removal. The system operates in both manual and semi-autonomous modes, allowing for user-directed movement of the surgical instrument initially, followed by autonomous operation along a generated tool path that optimally navigates through the identified additional tissue portions.
The surgical system also incorporates advanced navigation capabilities, including an anatomy tracker and a tool tracker, which work in conjunction with a localizer to generate tracking data. This data aids in accurately defining the poses of both the tissue and the surgical instrument. The controllers can create a virtual model of the tissue volume, enabling them to subtract the first removed portions to identify remaining areas needing attention. Furthermore, the system is designed to generate tool paths that avoid previously excised portions, potentially incorporating circuitous routes or adjustments in instrument velocity to enhance surgical outcomes. A display device is also included to visually indicate the areas of tissue that have been removed and those that still require intervention, thereby providing real-time feedback to the surgical team.
