Osteotomy verification marking nail and matched integrated driving-in and taking-out device thereof

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
