Abstract
A robotic surgical system includes a linkage, an input device, and a processing unit. The linkage moveably supports a surgical tool relative to a base. The input device is rotatable about a first axis of rotation and a second axis of rotation. The processing unit is in communication with the input device and is operatively associated with the linkage to rotate the surgical tool about a first axis of movement based on a scaled rotation of the input device about the first axis of rotation by a first scaling factor and to rotate the surgical tool about a second axis of movement based on a scaled rotation of the input device about the second axis of rotation by a second scaling factor that is different from the first scaling factor.
Claims7
A robotic surgical system comprising:
- a linkage moveably supporting a surgical tool relative to a base;
- an input device rotatable about a first axis of rotation, the input device being rotatable from an idle position in a first input direction about the first axis of rotation towards a first rotated position;
- and
- a processing unit in communication with the input device and operatively associated with the linkage to rotate the surgical tool about a first axis of movement in a first output direction when the input device is rotated from the idle position towards the first rotated position and to maintain a radial position of the surgical tool about the first axis of movement when the input device is in the idle position.
