1. A surgical system, comprising:
- a surgical tool having an elongate shaft with an end effector at a distal end thereof, the surgical tool including a rotor;
a robotic surgical system tool driver configured to releasably couple to the surgical tool, the tool driver including a stator;
a sterile barrier located between the tool driver and the surgical tool such that when the tool driver is releasably coupled to the surgical tool, a magnetic field is configured to extend through the sterile barrier between the rotor on a sterile side of the sterile barrier and the stator on a non-sterile side of the sterile barrier and thereby drive a function of the end effector; and
a shield configured to provide a magnetic shield for the magnetic field.

Abstract
Various exemplary surgical tool and robotic surgical system interfaces are provided. In general, a sterile barrier can be positioned between a robotic surgical system and a surgical tool releasably coupled to the robotic surgical system. The surgical tool can be in a sterile environment on one side of the sterile barrier, and the robotic surgical system can be in a non-sterile environment on the other, opposite side of the sterile barrier. The robotic surgical system can be configured to control movement of the surgical tool releasably coupled thereto using a magnetic field that extends across the sterile barrier between the surgical tool and the robotic surgical system.

12. A surgical system, comprising:
-
a surgical tool having an elongate shaft with an end effector at a distal end thereof; a sterile barrier; a robotic surgical system tool driver configured to releasably couple to the surgical tool with the sterile barrier located therebetween, wherein the end effector is configured to move in response to generation of a magnetic field extending through the sterile barrier and between the surgical tool and the robotic surgical system; and a shield configured to provide magnetic shielding of the magnetic field. - View Dependent Claims (13, 14, 15, 16, 17)

18. A surgical method, comprising:
-
coupling a surgical tool to a tool driver of a robotic surgical system with a sterile barrier between the surgical tool and the tool driver such that the surgical tool is in a sterile environment; and causing a magnetic field to extend between a rotor of the surgical tool and a stator of the robotic surgical system through the sterile barrier and thereby move an end effector of the surgical tool, a shield surrounding the rotor and the stator providing a magnetic shield of the magnetic field. - View Dependent Claims (19, 20)
