Joint replacement surgical robot navigation and positioning system and method

Abstract

The embodiment of the invention discloses a joint replacement surgical robot navigation and positioning system and method. The system comprises a preoperative planning module which is used for carrying out segmentation and reconstruction of a hip joint according to the obtained medical image data of the hip joint, obtaining a three-dimensional model of the hip joint, carrying out the preoperative planning, and determining a surgical scheme; an optical navigation positioning module which is used for generating a navigation instruction according to the surgical scheme, registering the hip joint three-dimensional model according to the spatial position relationship between the hip joint of a patient and an operation probe to obtain a hip joint solid model, and determining the bone operation position of the patient according to the hip joint solid model; and a mechanical arm control module which is used for moving an end effector to the bone surgery position of the patient and controlling the end effector to perform osteotomy, filing and press-fit operation on the hip joint according to the navigation instruction. Preoperative planning is executed through the orthopedic surgery robot, surgery operation is completed at a high level, the operation intensity of doctors can be greatly reduced, the operation time is saved, and the operation precision is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a navigation and positioning system and method for a joint replacement surgery robot. Background technique [0002] In recent years, hip replacement, as the most effective treatment for hip diseases, has been widely carried out at home and abroad. my country is a country with a high incidence of hip joint diseases, and it is estimated that nearly 10 million new patients will suffer from various hip joint related diseases in Asia. However, traditional joint replacement surgery has imperfect preoperative planning, insufficient preoperative preparation, lack of precise intraoperative navigation and positioning, relies heavily on doctors' surgical experience, cumbersome operations, and poor repeatability, resulting in a high incidence of postoperative complications. Seriously restrict the effect of hip replacement surgery. Contents of the invention [0003] Due to the above-ment...
