Junkaijie Robotic Arm Surgical Stereotactic Positioning…

Overview

The Junkai Jie Robotic Arm Surgery Stereotactic Positioning System is an image-guided spinal surgery robotic system developed by Point Robotics, a Taiwan-based medical robotics firm. The system integrates an articulated robotic arm with stereotactic navigation for minimally invasive spine surgery. Key innovations include an O-Arm/CT compatible navigation module, an end-effector with a lockable arm for rigid instrument fixation during screw placement, and optical tracking for direct real-time verification of tool position. The system's flagship 12-axis configuration (likely with a 6-axis arm and additional positioning axes) targets the US$14.3 billion minimally invasive spine surgery market, addressing the critical challenge of reducing intraoperative radiation exposure by potentially eliminating the need for multiple X-ray verification scans. It obtained Taiwan's regulatory approval (TFDA) for its navigation and positioning module in August 2025, and is positioned as a surgical assistant for pedicle screw placement, reducing surgeons' reliance on intraoperative fluoroscopy/CT and improving precision. The device incorporates surgeon 'egg-carving' techniques translated into robotic control for high dexterity, and is comparable to but distinct from competitors like Mazor X and Medtronic Globus ExcelsiusGPS.
