Applications
The KUKA LBR Med serves diverse medical applications including minimally invasive surgery assistance, where it provides stable instrument guidance and positioning. In orthopedic procedures, it enables precise bone milling and implant placement with consistent accuracy. The robot also supports diagnostic imaging by positioning ultrasound probes and other scanning devices, and assists in rehabilitation therapy through controlled movement exercises and patient support.
Beyond the operating room, the LBR Med finds applications in pharmaceutical manufacturing, medical laboratory automation, and medical device testing. Research institutions utilize it for biomechanical studies and development of new surgical techniques. Its certification status makes it uniquely suited for any application requiring direct interaction with patients or sterile medical environments where traditional industrial robots cannot be deployed.
Technical Highlights
The LBR Med's core innovation lies in its comprehensive joint torque sensing technology, which provides real-time force feedback across all seven axes. This enables compliant motion control where the robot can adapt to external forces and collaborate safely with surgeons and medical staff. The robot's controller implements advanced safety functions that immediately respond to unexpected contacts, making it suitable for direct patient interaction under medical supervision.
The robot's mechanical design emphasizes cleanability and material compatibility with medical environments. Its 800 mm reach combined with seven degrees of freedom provides exceptional dexterity in confined spaces typical of surgical settings. The LBR Med's control architecture supports integration with medical imaging systems and surgical planning software, enabling image-guided procedures and autonomous execution of pre-planned trajectories with consistent sub-millimeter accuracy.
