This application relates to the field of medical devices and discloses a multi-arm orthopedic medical robot, including a mounting frame, a camera, a robotic arm, and orthopedic instruments. It also includes a receiving cylinder hinged to the top of the orthopedic instruments via a set of hinge blocks, the inner cavity of which is filled with a sealing fluid; and a telescopic column, which is sealed within the receiving cylinder. This invention utilizes multiple sets of fluid guide ports at the bottom of the telescopic column to allow the sealing fluid to flow along these ports during relative sliding of the receiving cylinder and the telescopic column, maintaining their telescopic function. Once the robotic arm has adjusted the angle of the orthopedic instruments, the receiving cylinder and the telescopic column cease relative movement, becoming a rigidly connected unit. In this state, the reaction force generated during drilling, hammering, or other operations on bone areas by the orthopedic instruments is directly transmitted to the mounting frame through the receiving cylinder and the telescopic column, thereby protecting the robotic arm and maintaining the stability of the device.
