Planning method and device for tibia osteotomy intelligent navigation system

Abstract

The invention provides a planning method and device for an intelligent navigation system for tibia osteotomy. The method comprises the following steps: performing image segmentation and three-dimensional image reconstruction on a medical image of a lower limb skeleton of a human body to obtain a three-dimensional image containing a tibia and a fibula; key point recognition is conducted on the three-dimensional image containing the tibia and the fibula, and parameter information of the tibia osteotomy part is determined; generating an osteotomy guide plate model based on the parameter information, and acquiring data of the osteotomy guide plate model; and manufacturing the tibia high-position osteotomy guide plate through 3D printing based on the acquired data of the osteotomy guide plate model. The design time of the osteotomy guide plate can be greatly shortened, the waiting time of a patient before an operation is shortened, the design difficulty is reduced, the pain of the patient can be relieved as soon as possible, the design accuracy of the osteotomy guide plate can be improved, the operation time is shortened, the operation risk is reduced, and accurate correction of the force line of the lower limb of the patient is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a planning method and device for an intelligent navigation system for tibial osteotomy. Background technique [0002] Degenerative osteoarthritis of the knee is often accompanied by varus deformity of the knee joint, and changes in the weight-bearing biological stress in the joint, which leads to the imbalance of the lower extremity force line, which in turn accelerates the wear of the knee joint cartilage. At present, High Tibia Osteotomy (HTO) is the most common surgical method for the treatment of early and mid-stage knee osteoarthropathy caused by knee varus. The treatment principle is to transfer the pressure of the worn medial compartment of the knee joint to the relatively normal lateral compartment through the proximal medial osteotomy of the tibia, thereby improving the function of the knee joint by correcting the axis of the knee joint and increasing the stabili...
