Title:
TUNNEL POSITION DETERMINATION SYSTEM AND METHOD FOR ANTERIOR/POSTERIOR CRUCIATE LIGAMENT RECONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2022/048553
Kind Code:
A1
Abstract:
Provided are a tunnel position determination system and method for anterior/posterior cruciate ligament reconstruction, relating to the technical field of ligament reconstruction. The system comprises: a coordinate system establishment module used for establishing a femoral coordinate system and a tibial coordinate system respectively; a feature point selection module used for selecting a femoral bone feature point and a tibial bone feature point; and a tunnel position determination module used for, on the basis of the femoral bone feature point and the tibial bone feature point, determining a femoral point and a tibial point during reconstruction, and by means of the femoral point and the tibial point, determining a specific tunnel position of anterior cruciate or posterior cruciate ligament reconstructed tunnel. Provided is a selection method for the femoral point and the tibial point during tunnel reconstruction, enabling a specific path of the reconstructed tunnel to be formed more accurately.
