Abstract: A method and apparatus for variable speed osteotomy are provided. The method includes: controlling a bone saw to perform an osteotomy operation at a first speed in a first tissue; acquiring a power representation signal of the bone saw; processing the power representation signal to acquire a high frequency component and a low frequency component; performing, based on a predefined threshold, a denoising operation on the high frequency component to obtain a denoised high frequency component; reconstructing the denoised high frequency component and the low frequency component to obtain a denoised power representation signal; determining, based on the denoised power representation signal, whether the bone saw enters a second tissue which has different properties from the first tissue; and when determined that the bone saw enters the second tissue, controlling the bone saw to perform an osteotomy operation at a second speed.

Abstract: An orthopedic surgical robot system; the orthopedic surgical robot system comprises: a robotic arm (10), a distal end (170) of the robotic arm (10) being used for providing a locked working point (O) for the orthopedic surgical robot system; a multi-link mechanism (20), wherein the multi-link mechanism (20) comprises: a first link (210), the first link (210) being coupled to the distal end (170) of the robotic arm (10); and a second link (220), a proximal end of the second link (220) being connected to the first link (210) in a movable manner, so that the movement of the second link (220) relative to the first link (210) provides the orthopedic surgical robot system with a locked working plane relative to the locked working point (O); a bone saw (30), the bone saw being coupled to the distal end of the second link (220) and operable in the locked working plane; and a control system (40), the control system (40) being coupled to the robotic arm (10), and controlling, on the basis of a basic control amount of t
