Surgical robot system

A surgical robot system relates to the fields of minimally invasive operation, clinical surgical operation and the like, in particular to the minimally invasive operation with the high-precision requirement. The system comprises three same mechanical arms which are symmetrically arranged on a fixed platform; each mechanical arm has six degrees of freedom; the specific gesture of an operation clamping device is realized by the coordinated movement of the six degrees of freedom, thus achieving the positioning movement required in the operation process. The six degree-of-freedom mechanism arm realizes the movement decoupling, is convenient for the gesture control of the operation clamping device, not only has low requirement on the hardware of the control system, but also can reach the high-precision movement control; and the surgical robot system has simple structure, is convenient to operate and easy to maintain and can realize the minimally invasive operation with high-precision requirement.
