of modern surgical practices. Powered by advanced robotic systems, high-precision imaging, and intelligent navigation technologies, surgical robots enable highly accurate procedures with improved treatment outcomes and reduced trauma.
Among the core components of robotic-assisted surgery, navigation and positioning technologies play pivotal roles. These two elements work hand-in-hand to ensure surgical precision, efficiency, and safety.
Surgical Navigation: Planning and Guiding the Surgical Path
Navigation refers to the planning and guidance of the surgical pathway. It helps surgeons visualize the anatomy and determine the safest and most effective route for the procedure. Efficient navigation shortens operating time, minimizes surgical risks, and improves overall accuracy. Two widely used navigation methods include:
1. Reverse Planning Navigation
This method uses real-time intraoperative data toNavigation: Guiding the Surgical Route
Navigation technology serves as the “map and compass” of robotic surgery. It helps plan the optimal surgical path and guide surgical instruments in real time, reducing intraoperative risks and improving surgical efficiency.
There are two main types of navigation technologies commonly used in robotic systems:
- Inverse Planning Navigation
This technique involves reverse path planning based on real surgical data. By analyzing the patient’s CT, MRI, or other imaging data alongside the robot’s instrument range, the system calculates the safest and most efficient surgical path. This is particularly useful in surgeries involving complex anatomical structures, such as the spine or brain. - Virtual Reality (VR) Navigation
VR navigation uses advanced image processing to convert real-time surgical data into immersive 3D environments. Surgeons can simulate the surgical field, visualize procedural steps, and track instrument trajectories, all in real time. This provides visual guidance and enhances spatial awareness during complex or minimally invasive procedures.
- Positioning: Pinpointing Surgical Targets
Positioning technology is responsible for marking surgical sites and enabling accurate localization of target lesions. It ensures the robot arm can autonomously detect and access internal anatomical targets with high precision.
The most commonly used positioning technologies include:
- 3D Reconstruction Technology
This approach uses medical imaging (such as CT, MRI, or PET scans) and computational algorithms to reconstruct a 3D model of the patient’s anatomy. It provides a visual reference for surgical planning and intraoperative guidance.
Traditional image-based registration methods, like fiducial marker alignment, often depend heavily on image quality. In contrast, Perlove Medical’s independently developed PL300B Spinal Navigation and Positioning System introduces an adaptive registration method based on trajectory recognition, which offers high accuracy and is less affected by image quality. Additionally, it simplifies the workflow by eliminating the need to change tool tips during the registration process. retrospectively calculate the optimal surgical path. By combining the tool’s working space with patient imaging data (such as CT or MRI scans), reverse planning enables the robot to determine a precise surgical route. This enhances both safety and accuracy.
2. Virtual Reality (VR) Navigation
VR navigation transforms surgical data into a virtual 3D environment, simulating the anatomy, surgical instruments, and operating scene. Surgeons can interact with this immersive simulation for enhanced visualization, decision-making, and real-time procedural guidance, especially during complex surgeries.
• Magnetic Tracking Technology
This method utilizes changes in the surrounding magnetic field to determine the position and orientation of surgical instruments. It offers several advantages, including high accuracy, non-invasiveness, and zero radiation exposure, making it ideal for applications in pediatrics, neurosurgery, and other radiation-sensitive procedures.
Optical Tracking Technology
Optical positioning is based on cameras and computer vision systems. By identifying reflective markers or LED indicators on the instruments or patient’s body, the system can track surgical tools in real time with exceptional precision. This technology is widely integrated into surgical navigation platforms due to its fast response and high reliability.
Innovative Registration by Perlove Medical
Traditional 3D image registration often relies on visual markers and is sensitive to image quality. Perlove Medical’s self-developed PL300B spinal navigation and positioning system introduces an advanced adaptive registration method based on trajectory recognition. This approach offers higher registration accuracy, is unaffected by image resolution, and allows for smoother workflows without the need to change instrument tips during the procedure.
Adaptive Registration (Trajectory-Based): Precise, reliable, and user-friendly.
Navigation and positioning are not just technical components—they are the foundation of modern robotic surgery. As technologies like 3D reconstruction, adaptive registration, and optical/magnetic tracking continue to evolve, they enable surgical robots to deliver even higher levels of safety, precision, and patient outcomes.
