Disclosed are a surgical instrument and a coupling structure for a surgical robot. The surgical instrument, which may be mounted on a surgical robot for operation, and which may perform a maneuver required for surgery by moving and rotating an effector joined to one end of the surgical instrument, may include: a first driving component that rotates about a first axis, a second driving component joined to the first driving component that rotates the first driving component about a second axis which intersects the first axis, a third driving component joined to the second driving component that rotates the second driving component about a third axis which intersects the second axis, a shaft joined to the third driving component that extends in one direction and has the effector joined to one end, and a housing that holds the first driving component, the second driving component, and the third driving component. As the driving components for moving the effector can be provided in a systematically connected form, instead of having each of the driving components arranged independently, the size of the surgical instrument may be reduced. Also, by forming the driving components as a 3-dimensional structure instead of using 2-dimensional pulleys, the transfer of forces required for the complex movements of the effector can be implemented simultaneously. Embodiments of the present invention can also readily be applied to a snake type surgical instrument. |
