Advancing Precision Minimally Invasive Spine Surgery
Introduction: Transforming Spine Surgery Through Precision Medicine
Spine surgery is experiencing a significant transformation driven by precision medicine, digital healthcare, and intelligent surgical technologies. The evolution from traditional experience-based procedures toward robotic-assisted spine surgery represents a new era of accuracy, safety, and efficiency.
Lumbar disc herniation (LDH) is one of the most common spinal disorders, often resulting in low back pain, radiating leg pain, sensory abnormalities, and functional impairment. With increasing expectations for less invasive treatment, faster recovery, and improved surgical outcomes, minimally invasive spine surgery has become an important direction in modern spinal care.
Transforaminal Endoscopic Lumbar Discectomy (TELD) has emerged as a key technique in minimally invasive spine surgery. By accessing the pathology through the intervertebral foramen under endoscopic visualization, TELD enables targeted decompression while preserving surrounding anatomical structures.
However, TELD remains technically demanding. Accurate determination of the entry point, surgical trajectory, and target location is essential, particularly in patients with complex anatomy or challenging pathologies.
The integration of the PL300B robotic navigation system provides a new approach to improving surgical precision. By combining three-dimensional imaging, intelligent surgical planning, navigation technology, and robotic positioning assistance, PL300B supports surgeons in performing safer, more accurate, and standardized minimally invasive spine procedures.
1. TELD: A New Standard in Minimally Invasive Spine Surgery
Traditional open spine surgery can effectively relieve neural compression but may involve extensive soft tissue exposure and longer recovery periods.
With advances in minimally invasive concepts, Transforaminal Endoscopic Lumbar Discectomy (TELD) has become an important treatment option for lumbar disc herniation.
Through a small working channel established via the intervertebral foramen, surgeons can directly visualize and treat pathological structures, including:
- Herniated nucleus pulposus removal;
- Nerve root decompression;
- Disc fragment removal;
- Targeted bony decompression when required.
TELD maximizes preservation of normal anatomical structures while achieving effective neural decompression, providing patients with a less traumatic surgical option.
2. Challenges in Conventional TELD Procedures
2.1 Complex Anatomy Requires Personalized Surgical Planning
The lumbar spine presents considerable anatomical variation among patients.
Differences in:
- Foraminal morphology;
- Disc herniation location;
- Nerve root anatomy;
- Bony structures;
may influence surgical access and technical complexity.
Depending on the clinical condition, different approaches may be selected, including:
- Transforaminal approach;
- Extraforaminal approach;
- Foraminal enlargement procedures;
- Interlaminar approach.
Each approach requires accurate planning of the entry point, trajectory, and target position.
2.2 The Need for More Accurate Surgical Localization
Successful TELD depends on establishing a safe and precise working pathway.
Traditional procedures mainly rely on:
- Preoperative MRI and CT evaluation;
- Intraoperative fluoroscopic guidance;
- Surgeon experience.
In complex cases, repeated adjustments may be required to achieve an optimal trajectory.
Therefore, improving pathway planning and reducing procedural uncertainty have become essential goals in the development of advanced minimally invasive spine surgery.
