Minimally invasive spinal surgery navigation reduces the risk of reoperation and the incidence of complications.

Due to the aging and the increase of obese population, the orthopedic surgery market is growing, and the global spinal surgery market roughly estimates that there are more than one million operations every year. It also drives the proportion of minimally invasive spine surgery to increase year by year. Compared with the daunting traditional spinal surgery, spinal navigation has the advantages of improving the accuracy of screw placement and reducing radiation exposure.

What is the most common disease that requires spinal surgery? Spinal disc herniation (commonly known as spinous process) is the most common disease that requires spinal surgery. It will cause the patient's nerves to be compressed. Most patients can relieve symptoms through conservative treatment. However, there are still a few patients with sensory, motor and even defecation disorders due to long-term nerve compression. At this time, surgical intervention is often needed to prevent the course of the disease from worsening.

Traditional spinal surgery is covered by soft tissues such as muscles, ligaments and skin, which is irregular and irregular. It is impossible to know whether the angle and position of artificial joints and steel nails are consistent with the parts we want to implant into the human body. In the past, the traditional surgical method was to confirm the position of the implant with X-ray and then adjust it, which would cause two problems. First of all, the implant needs to be adjusted many times to reach the position, which affects the stability of the bone. Because the location is confirmed by X-ray, both patients and doctors are at risk of exposure to radiation dose. In addition, if the patient suffers from osteoporosis, the surgical implant may be at risk of loosening.

Manager Zhuang Shichang of Yb-Ti Technology Co., Ltd., a minimally invasive spinal surgery navigation company, said that with the development of computer technology and sensor technology, the medical system is constantly improving. Many medical images are based on the improvement of software technology and positioning technology, providing doctors with "accurate" surgical auxiliary information, and further providing information for robotic arms to perform "fine" surgical actions, which has become the main axis of the development of a new generation of surgical treatment systems.

Through the patented perspective optical system device and the infrared camera connected to the doctor's head, it is convenient for the doctor to use infrared projection, and the navigation data, such as 3D images of longitudinal and transverse sections of the spine, are projected on the doctor's retina in time after being processed by software such as image analysis, advanced visualization system, scene recognition, machine learning and data analysis, so that the doctor can immediately check the affected part and perform surgery.

Zhuang Shichang said that the minimally invasive spinal surgery navigation system provides assistance in preoperative surgery planning, intraoperative image alignment, and surgical guidance. It is characterized by using special 2D/3D image registration software to provide 3D spine image segmentation and intraoperative alignment, without expensive intraoperative imaging equipment, and can be applied to general surgical equipment. Navigation surgery can improve the accuracy of surgery and reduce the risk of reoperation and the incidence of complications.
