Abstract

The embodiment of the invention provides an intraoperative prosthesis recommendation method and system for a knee joint surgical navigation system, and belongs to the technical field of surgical navigation, and the method comprises the steps: reconstructing a three-dimensional model of a knee joint in software through three-dimensional CT by using a navigation system in a surgical process; acquiring registration positioning points in the femur and the tibia of the knee joint through a probe; performing data calculation on the positioning point parameter combination to obtain prosthesis-related femoral prosthesis type parameters, femoral prosthesis in-vitro and in-vivo turning angles, femoral prosthesis in-vitro turning angles, femoral prosthesis positioning parameters and tibial prosthesis type parameters; and determining a specific model and a mounting position of a prosthesis needing to be recommended based on the femoral prosthesis type parameter, the femoral prosthesis in-vitro and in-vivo turning angle, the femoral prosthesis in-vitro turning angle, the femoral prosthesis positioning parameter and the tibial prosthesis type parameter. Through the treatment scheme disclosed by the invention, subjective factors during selection of the femoral prosthesis and the tibial prosthesis are avoided, and the operation is easy.

Description

Technical field [0001] The present disclosure relates to the field of surgical navigation technology, in particular to a knee surgical navigation system intraoperative prosthesis recommended method and system. Background [0002] At present, there are many planning systems that support preoperative planning according to CT images, but in actual clinics, it is not convenient to accurately perform surgery according to preoperative planning, one is that there will be many unexpected situations during surgery, and the other is that preoperative images are static, and it is difficult to assess the motor performance of joints. Therefore, clinicians only use preoperative planning as a reference during surgery, and select prosthesis models and locations empirically during surgery, but this loses the accuracy of the navigation system. However, accurate prosthesis matching can reduce complications such as knee pain, prosthesis loosening, prosthesis wear, and postoperative bleeding, thereby...
