Abstract
Embodiments relate to robotic arm assemblies. The robotic arm assembly includes an end-effector assembly. The end-effector assembly includes an instrument assembly. The instrument assembly includes an instrument and instrument driven portion. The elongated body includes an instrument central axis. The instrument driven portion includes a first central axis. The instrument driven portion is secured to a proximal end of the instrument in such a way that, when the instrument driven portion is driven to rotate, the instrument rotates relative to the first central axis. The end-effector assembly includes an instrument drive assembly. The instrument drive assembly includes an instrument drive portion. The instrument drive portion includes a second central axis. The instrument drive portion is configured to drive the instrument driven portion to rotate the distal end of the instrument relative to the first central axis. The second central axis intersects with and orthogonal to the first central axis.
