Abstract: One embodiment of the invention relates to a system for placement of a cannula and an internal shaft into a patient including a base, a linear drive mechanism coupled to the base and a rotation mechanism coupled to the base. The base includes an attachment mechanism configured to be mechanically coupled to the patient to maximize placement accuracy. The system further includes a cannula coupled to the linear drive mechanism. The cannula has a longitudinal axis, a lumen, and a distal opening. The linear drive mechanism is configured to move the cannula in a linear direction along the longitudinal axis into the body and the rotation mechanism is configured to rotate the cannula about the longitudinal axis. The system further includes a shaft drive mechanism coupled to the linear drive mechanism and the rotation mechanism and a shaft slidably housed within the lumen of the cannula.
