Cirq at United States

Brainlab, founded in 1989 in Munich by Stefan Vilsmeier, is a large navigation- and software-first medical-technology company, and its Cirq is the genuine robotic arm in its portfolio: a lightweight, roughly ten-kilogram arm that mounts on the operating-room bed rail and aligns instruments along pre-planned trajectories for drilling and spinal-screw placement, derived from Brainlab's 2019 acquisition of Medineering, with a variant for functional neurosurgery. It is FDA 510(k)-cleared for spine, cleared as the Cirq Robotic Alignment Module alongside the Loop-X mobile imaging robot around 2021, and is CE-marked.

The registry deliberately scopes this entity to the Cirq arm rather than Brainlab's broader navigation and software catalog, since Brainlab is navigation-software-first and most of its products fall outside a surgical-robot cohort, with Brainlab recorded as the parent maker and Cirq as the deployable robot; this is the follow-on deferred from the surgical foundational ingest. On the autonomy spectrum Cirq is a passive trajectory-alignment robot that positions and holds instruments along a planned path while the surgeon executes, the lowest-autonomy class in the surgical cohort, in contrast to Brain Navi's NaoTrac with autonomous registration and Moon Surgical's Maestro with its shipped ScoPilot AI.

The exact Cirq spine 510(k) date and clearance number are not pinned in this pass beyond approximately 2021, the installed-base count is not verified, and Brainlab's frequently cited revenue figure is a stale 2016 number that is not asserted.
