Augmented reality navigation for precise implantation of LC2 pelvic tunnel screws in minimally invasive surgery

: Due to the considerable risk of trauma, traditional open surgery has been gradually replaced by minimally invasive surgery using tunnel screws. However, during minimally invasive pelvic surgery, surgical navigation can be improved by effectively using the augmented reality technique. This can further improve the accuracy of the surgery and reduce risks. : This study adopts a registration approach based on the patient coordinate system and uses a specific manual setting comparison method to select the suitable 3D corner detection parameters. : After experiments, this strategy can effectively improve the accuracy of positioning during surgery. It achieves a balance in detection time and accuracy, which further reduces risks and injuries during surgery. : Our technique can achieve more precise and safer results during minimally invasive pelvic surgery, which shows its great value and potential in the clinic.
