As medical technology advances, surgical robotics has become a critical branch in healthcare, demonstrating significant potential and value in numerous surgical procedures. The application of surgical robots has emerged as a powerful force driving the development of the medical industry. Perlove Medical’s Spinal Surgery Navigation System, an integrated solution combining “3D C-arm + Orthopedic Surgical Robot,” effectively assists hospitals in overcoming the challenges of puncture accuracy, shortening the learning curve for surgeons, and providing patients with a more precise, safe, and efficient treatment experience.
Case Study: Robot-Assisted Percutaneous Screw and Rod Fixation Surgery
- Patient: 71-year-old male with a T8 vertebral compression fracture.
- Procedure: Robot-assisted percutaneous screw and rod fixation surgery.
Surgical Challenge – Image Acquisition
The thoracic vertebrae are adjacent to the lungs, and the patient’s respiratory movements can cause relative displacement of the vertebral segments, making it challenging to obtain clear and stable images. High-quality imaging is essential for precise navigation. In thoracic surgery, if the movement caused by breathing is not effectively controlled, it can reduce navigation accuracy and increase surgical risk.
Perlove Medical Navigation System Solution
- High-Definition 3D Imaging: Perlove Medical has been refining its 3D imaging technology for 13 years. The self-developed 3D C-arm provides clear and stable 3D images, ensuring imaging support for precise thoracic surgery.
- Sub-Millimeter Accuracy: The Perlove Medical 3D C-arm and orthopedic surgical robot are developed on the same technology platform, featuring integrated adaptive registration and lossless image transmission technologies. This ensures higher overall coherence with accuracy reaching sub-millimeter levels.
- Rapid Scanning: With the anesthetist’s proper control of breathing and the 3D C-arm’s rapid scanning mode, images can be captured in a short time, reducing interference from respiratory movements.
Surgical Challenge – Path Planning
The pedicles of the thoracic vertebrae are narrower than those of the lumbar vertebrae and are surrounded by critical nerves and blood vessels, making the choice of screw size and length crucial. Screws that are too thick may damage the pedicle, while thinner ones are prone to deformation and insufficient fixation strength. Overly long screws may penetrate the anterior vertebral edge, causing damage, whereas shorter screws may not provide adequate fixation.
Perlove Medical Navigation System Solution
With robot-assisted surgery, surgeons can not only complete the path planning for multiple screws in a single step under image guidance, enhancing surgical efficiency, but also accurately select the screw’s angle, diameter, and length, improving the success rate of the surgery.
Surgical Challenge – Precise Screw Placement
In traditional open surgery, the surgical field of the thoracic vertebrae is relatively limited, and screw placement largely relies on the surgeon’s experience and tactile feedback, which introduces a degree of subjectivity.
Perlove Medical Navigation System Solution
Perlove Medical’s orthopedic surgical robot, equipped with a high-precision mechanical arm, automatically and accurately locates the puncture point according to the planned path and angle. After the surgeon inserts the Kirschner wire, the anterior and lateral images show the accuracy meets expectations, allowing the surgeon to complete screw placement and other subsequent surgical operations.
Lower Radiation, Smaller Incisions, Greater Care: The Advantages of Robot-Assisted Surgery
- Lower Radiation, Safer Procedures: In traditional open surgery, surgeons often use X-ray imaging multiple times to ensure accurate screw placement. The use of surgical robots can significantly reduce the frequency of intraoperative imaging, effectively lowering the radiation exposure for both doctors and patients, thereby safeguarding their health.
- Minimally Invasive Surgery for Faster Recovery: The precise positioning provided by the robot allows surgeons to perform surgery with smaller incisions and shorter anesthesia times. Compared to traditional open surgery, minimally invasive procedures significantly reduce patient discomfort and postoperative recovery time, with a lower incidence of postoperative complications, aiding in patient recovery.
In this case, Perlove Medical’s Spinal Surgery Navigation System successfully performed a percutaneous screw and rod fixation surgery, achieving precise positioning and minimally invasive treatment for thoracic vertebral fractures. The patient recovered well postoperatively. The successful application of navigation technology has brought patients a more precise, safe, and efficient surgical treatment plan, while also providing strong support for the further development of medical technology!
