Introduction: i-Navi Biomedical Inc., founded by Prof. Ching Shiow Tseng and his team members with more than 20-years’ experience in surgical navigation system development, is a company specialized in developing image-assisted/robotic surgical navigation systems for neurosurgery and orthopedic surgery. The 2D/3D C-arm or CT/CTA/MRI images based i-Navi robotic surgical navigation system (robot is an option) for spine/brain surgery enables surgeons to accurately and efficiently position surgical instruments and implants during operations. Using the i-Navi navigation system in minimally invasive spine/brain surgery can significantly reduce X-ray radiation exposure, improve positioning accuracy and surgical risk, and even reduce operation time. Clinical applications of the input image assisted navigation system have been tested and validated at Cathy General Hospital and Tao-Yuan General Hospital. Filing applications for FDA/TFDA approval will be done in one year. The company's goal aims to develop advanced robotic surgical systems to assist medical treatments and improve patients' health. Integration of new technologies such as AI, AR/MR into i-Navi systems to enhance system functions and capabilities is in progress.

Solution: In conventional brain surgery, surgeons can only use preoperative images (CT, MRI, or CTA) and clinical experience to analyze the brain lesion tissue anatomy and plan an appropriate surgical path to avoid damaging important tissues of the brain. If the cerebral artery is injured during operation, it will cause bleeding or even death of the patient. This product integrates a CT image assisted surgical navigation system and 3D display of AR glasses to align the 3D artery model reconstructed from CTA images with the patient. The 3D intuitive visualization of the AR glasses assists the surgeon to accurately plan a safe surgical path that can avoid cerebral arteries and to position the surgical instruments according to the planned path intraoperatively. The 3D skull model containing blood vessels can also be printed using 3D printing technology. With the AR glasses, the 3D scene combining the cerebral artery model, surgical instruments and the skull model can be instantly displayed, and thus the surgeon can perform the operation simulation or surgical training. Through the physical demo of the AR based navigation system for brain surgery in Bio Asia, we expect the participants (surgeons/ biomedical industry/ investors) will gain a deeper understanding of the product and look forward to future cooperation opportunities.
