Prostate biopsy is the gold standard for preoperative diagnosis of prostate cancer. The magnetic navigation system is a system equipped with electromagnetic vibration tracking technology, which can solve the problem of displaying the puncture needle path during biopsy, thereby assisting the operator to safely and smoothly place the biopsy needle into the target position. At present, the magnetic navigation system has been widely used in biopsy operations of different organs in multiple systems, such as: nerve block in anesthesiology, thyroid biopsy, kidney biopsy, etc. It has been confirmed to improve the success rate of biopsy respectively, and has good application value. However, the biopsy routes tracked and simulated by the existing magnetic navigation system are set in the ultrasound plane, while in prostate biopsy, the insertion direction of the needle is perpendicular to the direction of ultrasonic emission, so the existing technology can not be directly applied to prostate biopsy.
This study intends to optimize the existing equipment, develop a new electromagnetic navigation system for transperineal prostate targeted biopsy, realize real-time navigation of prostate biopsy needle in the model, and record and analyze data and images. Adjust the equipment according to the deviation, develop and upgrade the software to focus on the application of benign and malignant prostate lesions. And, in the completion of model and surgical specimen experiments, the new electromagnetic navigation system was further applied to the clinic, through prospective, single-center, randomized controlled studies, to verify its maneuverability, safety and effectiveness in guiding transperineal prostate targeted biopsy.
