Flexible tool dual driving mechanism for surgical robot

The invention discloses a flexible tool dual driving mechanism for a surgical robot. The flexible tool dual driving mechanism for the surgical robot comprises a horizontal connecting plate. A first driving support is fixedly installed on the horizontal connecting plate. A motor is installed at one end of the horizontal connecting plate. A first driving wheel is fixedly connected to an output shaft of the motor. A second driving support is fixedly installed at the other end of the horizontal connecting plate. A first guide wheel, a second guide wheel, a middle transmission wheel and a second driving wheel are installed on the second driving support. A shell connecting base is fixed to the second driving support. An auxiliary driving wheel is connected to the shell connecting base. An auxiliary driving wheel shell is arranged on the shell connecting base in a covering mode. Two holes are symmetrically distributed in the auxiliary driving wheel shell in the vertical direction. Compression springs are installed in the two holes respectively. One ends of the two compression springs are pressed at the two ends of a rotary shaft of the auxiliary driving wheel respectively. The flexible tool dual driving mechanism for the surgical robot is convenient to operate and practical and can be conveniently applied to the robot for driving a flexible tool.
