Robots and navigation systems that plan the path of a biopsy or ablation needle on a CT scan and then hold, aim or steer the needle along it, to reach small targets in the lung, liver or kidney with fewer adjustments.
Most are cleared as accessories to CT systems (FDA product code JAK). XACT Robotics' XACT ACE (K221116, 13 May 2022) is "a user-controlled positioning system intended to assist in the planning and advancement of an instrument during Computed Tomography (CT) guided percutaneous procedures". Quantum Surgical's Epione (K211645, 24 February 2022) is a stereotactic accessory for planning and manual advancement, indicated for liver ablation among other uses. Others are iSYS's MICROMATE (K203720, 22 June 2021), Cascination's CAS-One IR (K232022, 13 March 2024), IMACTIS CT-Navigation (K162314, 24 April 2018), Clear Guide's SCENERGY (K201188, 30 September 2020) and Philips' PercuNav image fusion and navigation (K201053, 14 May 2020).
A CT dataset defines the target and entry point; a robot arm or patient-mounted device aligns a needle guide to the planned trajectory, with optical or electromagnetic tracking and repeat CT to confirm the tip position.
