Abstract:
A control method and apparatus for a reaming tool of a surgical robot. The control method for a reaming tool comprises: acquiring, in a base coordinate system, an initial posture of a reaming tool and the position coordinates of a key point thereof; on the basis of a preset transformation matrix, transforming the reaming tool from the initial posture to a movement posture; and fixing the position coordinates of the top end of the reaming tool, controlling, by means of a robotic arm, the reaming tool to perform reaming at the movement posture, and adjusting the pose of the reaming tool according to a movement trajectory of the origin of a flange of the robotic arm. The control method further comprises: when a coordinate difference between the current position coordinates of a spherical center of an inner spherical surface of an acetabular cup and the position coordinates of a reaming depth limiting point is less than or equal to a preset threshold value, controlling, by means of the robotic arm, the reaming tool to stop moving.
