Abstract

The invention discloses an osteotomy verification marking nail which comprises a marking nail head, a marking nail upper section with a thread, a marking nail lower section without a thread and a marking nail conical tail section which are sequentially and coaxially connected from top to bottom, and can be used for a total knee joint replacement operation under the assistance of a robot to determine whether a bone target of the surgical robot is displaced relative to the bone of a patient. The invention further discloses a matched integrated driving-in and taking-out device of the osteotomy verification marking nail. The matched integrated driving-in and taking-out device comprises a driving-out and taking out column, a driving-out and taking-out hammer and a marking nail connector, wherein the driving-out and taking-out column comprises a driving-out and taking-out column top, a driving-out and taking-out rod, a driving-out and taking-out handle and a driving-out and taking-out column bottom; the driving-out and taking-out hammer comprises a knocking ring and a knocking handle; and the marking nail connector comprises a connector top and a connector column arranged at the bottom end of the connector top, a groove is upwards formed in the bottom end face of the connector column, and a cylindrical magnet, an upper-layer connector and a lower-layer connector are sequentially arranged in the groove from top to bottom. The integrated driving-in and taking-out device is convenient for doctors to rapidly drive in or take out marking nails in the operation, and can improve the operation efficiency.

Description

technical field [0001] The invention relates to an osteotomy verification marking nail and its supporting integrated driving and taking out device, belonging to the technical field of medical devices. Background technique [0002] China has gradually entered the aging stage, and the number of patients who need artificial joint replacement due to various degenerations, trauma, and tumors reaches more than one million every year, so there is a huge clinical demand for joint replacement surgery. However, conventional knee replacement surgery has its disadvantages and deficiencies: 1. Conventional knee replacement surgery has extremely high technical requirements for doctors, requires a large amount of surgical experience accumulation, and has a long learning curve; 2. Conventional knee replacement surgery operates largely Relying on instant performance, lack of precise preoperative planning; 3. It is difficult to achieve standardized and repeatable surgical results in conventio...
