Control arm for robotic surgical systems
First Claim
1. A control arm for a robotic surgical system, the control arm comprising:
- a base;
a swivel member rotatably supported on the base about a first axis of rotation;
a vertical member pivotally supported on the swivel member about a second axis of rotation;
a horizontal member pivotally supported by the vertical member about a third axis of rotation; and
a drive mechanism disposed on the base to independently rotate the swivel member about the first axis of rotation, pivot the vertical member about the second axis of rotation, and pivot the horizontal member about the third axis of rotation, wherein the drive mechanism includes;
a first lower pulley disposed about the first axis of rotation operably coupled to a second drive motor by a first pair drive cables; and
a first upper pulley disposed about the first axis of rotation and rotatably fixed to the first lower pulley, the first upper pulley operably coupled to the vertical member to pivot the vertical member about the second axis of rotation.

Abstract
A control arm for a robotic surgical system includes a base, a swivel member, a vertical member, a horizontal member, and a drive mechanism. The swivel member is rotatably supported on the base about a first axis of rotation. The vertical member is pivotally supported on the swivel member about a second axis of rotation. The horizontal member is pivotally supported by the vertical member about a third axis of rotation. The drive mechanism is disposed on the base and is configured to independently rotate the swivel member about the first axis of rotation, to pivot the vertical member about the second axis of rotation, and to pivot the horizontal member about the third axis of rotation.

11. A method of manipulating a control arm including a base, a swivel member rotatable relative to the base about a first axis of rotation, a vertical member pivotally supported by the swivel member about a second axis of rotation, and a horizontal member pivotally supported by the vertical member about a third axis of rotation, the method comprising:
-
activating a first drive motor to rotate the swivel member about the first axis of rotation; activating a second drive motor to pivot the vertical member about the second axis of rotation, wherein activating the second drive motor to pivot the vertical member about the second axis of rotation includes rotating a first lower pulley about the first axis of rotation which affects rotation of a first upper pulley about the first axis of rotation which affects rotation of the vertical member about the second axis of rotation; and activating a third drive motor to pivot the horizontal member about the third axis of rotation. - View Dependent Claims (12, 13, 14, 15, 16)
