Abstract
The da Vinci Surgical Robot comprises a base, a column, and multiple manipulator arms. Each manipulator arm includes upper and lower trolleys connected to the column via a first joint drive module, and a first driven arm, a second driven arm, and a drive arm connected to the ends of the upper and lower trolleys and sequentially connected via a second joint drive module. The drive arm includes a corner arm, a crank arm, a tilting arm, a forearm, a tilting support, and a trolley, connected sequentially. The first joint drive modules of the multiple manipulator arms are respectively connected to the column via a first transmission mechanism. The first transmission mechanism includes a motor and a belt drive assembly, the output end of which is connected to the first joint drive module. One end of the tilting arm and one end of the forearm are connected via a second transmission mechanism, the other end of the forearm is connected to the tilting support via a third transmission mechanism, and the other end of the tilting support is connected to the trolley via a fourth transmission mechanism. This design improves the flexibility of the robotic arm, ensures positioning accuracy, and features a rationally designed transmission mechanism, facilitating mass production and market promotion.
