Augmented reality operation navigation system for reconstructing anterior cruciate ligament

Abstract

The invention relates to the field of medicine, in particular to an augmented reality operation navigation system for reconstructing anterior cruciate ligament. The system is constituted by augmentedreality glasses, operation navigation software for reconstructing the anterior cruciate ligament, binocular vision, labeling needles, femur joint labels, tibia joint labels, a computer and vision tracking software, wherein the operation navigation software, the binocular vision, labeling needles, femur joint labels, tibia joint labels and the computer are installed on the augmented reality glasses, and the vision tracking software is installed on the computer. Before an operation, diagnosis image CT data and MRI data are subjected to image fusing and division processing, three-dimensional reconstruction is conducted, and a reconstructed three-dimensional model is subjected to pre-operation planning; in the operation, the labeling needles are adopted to collect knee joint dissection joints,the collected knee joint dissection joints and the pre-operation knee joint model are rectified, and according to labeling of the tibia and femur, the knee joint three-dimensional model and a planning path are displayed in real time in the augmented reality glasses. According to the augmented reality operation navigation system for reconstructing the anterior cruciate ligament, precise locating of the starting point and the ending point of the anterior cruciate ligament can be achieved, the problem that an existing endoscope technique operation is narrow in vision is solved, and the operationrisks are effectively lowered.

Description

technical field [0001] The invention relates to the medical field, in particular to an augmented reality surgical navigation system for anterior cruciate ligament reconstruction. Background technique [0002] The anterior cruciate ligament is located in the human knee joint and plays a role in fixing the femur and tibia and stabilizing the joint. In the event of impact or high-speed movement, it is easy to break. Arthroscopic precise intra-articular reconstruction using ligament substitutes through the tunnel is the most effective treatment modality. According to relevant studies, after ACL reconstruction, only nearly 50% of the patients' joint mobility returned to the preoperative level, and more than 90% of the patients showed signs of degeneration on X-ray films 7 years after the operation. Accurate positioning of the insertion points of the femoral and tibial tunnels is a key factor affecting the success of the operation. It is relatively easy to locate the insertion ...

Problems solved by technology

[0004] Although the application of VR has brought great convenience to surgery, doctors and physicians cannot synchronize the preoperative three-dimensional anatomical information with the anatomical information of the real intraoperative visual field, which requires doctors to relearn, which increases the burden on doctors
