Objective: The purpose of this study is to provide safe and accurate reference data for the implementation of transforaminal endoscopic (transforaminal TESSYSTM technology) surgery before surgery, and to verify its efficacy in guiding the treatment of prolapsed lumbar disc herniation during surgery and safety.Methods: The research group selected 78 patients with prolapsed LDH who underwent transforaminal surgery (2014.07~2021.09). Before surgery, we used image post-processing software (Vue PACS) to measure the safe horizontal distance, horizontal angle and head tilt angle during puncture according to the degree of prolapse on the patient's imaging data (DR, CT, MRI). Based on the relevant indicators measured preoperatively, it was verified whether the expected puncture goal was achieved during the operation and the evaluation of the efficiency and safety of the operation was verified.Result: According to statistics, Vue PACS can be used to determine the safe horizontal distance, horizontal angle and head tilt angle during puncture on the patient's preoperative imaging data. Targeted puncture was completed by using the data of three-dimensional measurement as a reference during the operation, and the operation was successfully completed. The efficiency and safety of the operation were 95.8% and 100%. Conclusion: Vue PACS can be quickly used to perform 3D measurements on preoperative imaging data of patients, and to develop personalized puncture planning to guide safe and accurate intraoperative puncture.
