Instrument carriage assembly for surgical system
First Claim
1. A robotic assembly configured to support, insert, retract, and actuate a surgical instrument mounted to the robotic assembly, the robotic assembly comprising:
- an instrument holder base member;
a motor housing moveably mounted to the instrument holder base member;
a carriage drive mechanism operable to selectively translate the motor housing relative to the instrument holder base member along an insertion axis of the surgical instrument;
a plurality of drive motors, each of the drive motors being mounted to the motor housing; and
a plurality of output drive couplings, each of the output drive couplings being drivingly coupled with a corresponding one of the drive motors, each of the output drive couplings being configured to drivingly couple with a corresponding input drive coupling of the surgical instrument;
wherein a first drive motor of the plurality of drive motors is elongated between a first end, and a second end, the first drive motor includes a first magnetic flux shield at the first end and a second magnetic flux shield at the second end, and the first magnetic flux shield is spatially separated from the second magnetic flux shield so that a portion of the first drive motor unshielded from magnetic flux exists between the first magnetic flux shield and the second magnetic flux shield.

Abstract
A robotic assembly is configured to support, insert, retract, and actuate a surgical instrument mounted to the robotic assembly. The robotic assembly includes an instrument holder base member, a motor housing moveably mounted to the instrument holder base member, a carriage drive mechanism operable to translate the motor housing along the instrument holder base member, a plurality of drive motors, and a plurality of output drive couplings driven by the drive motors. One or more of the drive motors includes one or more magnetic flux shields to inhibit magnetic interference with an adjacent drive motor and/or with an adjacent motor orientation sensor.
