US Patent 11504195 Active drive mechanism for simultaneous rotation and translation

An exemplary drive apparatus may include a roller assembly and a roller support. The roller assembly may have a first continuous surface, a second continuous surface, an open configuration for receiving an elongate member, and a closed configuration for securing the elongate member in the roller assembly. The roller assembly imparts axial motion to the elongate member along the first continuous surface, which maintains contact with the elongate member during the axial motion. The roller support rotates the roller assembly about the second continuous surface, which maintains contact with the roller support during rotational motion. The roller assembly and roller support to impart axial and rotational motion, respectively, independently of one another.
