Abstract: A robot system for use in surgical procedures has two movable arms, each arm having a six of degrees of freedom of movement and an end effector which can be rolled about its axis and an actuator which can slide along the axis for operating different tools adapted to be supported by the end effector. Each end effector including optical force sensors for detecting forces applied to the tool by engagement with the part of the patient. The robot is MRI compatible and can be configured to operate within a closed magnet bore. The arms are driven about vertical and horizontal axes by piezoelectric motors.

Abstract: Methods, devices (such as computer readable media), and systems (such as computer systems) for performing movements of a tool of a medical robot along a single axis that are achieved by electronically limiting the medical robot's movement to produce movement of the tool along the single axis rather than mechanically restricting the medical robot's movement to produce the single axis movement. The tool's movement will be along the single axis even if a user is moving an input device linked to the medical robot in other axes during the single axis movement. In addition, techniques are disclosed for automating the single axis movement such that it can be programmed to stop at a target location and start at or near a second (e.g.

Abstract: A robot system for use in surgical procedures has two movable arms each carried on a wheeled base with each arm having a six of degrees of freedom of movement and an end effector which can be rolled about its axis and an actuator which can slide along the axis for operating different tools adapted to be supported by the effector. Each end effector including optical force sensors for detecting forces applied to the tool by engagement with the part of the patient. A microscope is located at a position for viewing the part of the patient. The position of the tool tip can be digitized relative to fiducial markers visible in an MRI experiment. The workstation and control system has a pair of hand-controllers simultaneously manipulated by an operator to control movement of a respective one or both of the arms. The image from the microscope is displayed on a monitor in 2D and stereoscopically on a microscope viewer. A second MRI display shows an image of the part of the patient the real-time location of the tool.

Abstract: A surgical robot that includes at least one robotic arm having multiple joints and at least six degrees of freedom, the robotic arm also including: a magnetic resonance (MR) compatible structural material; multiple MR-compatible joint motors; and multiple MR-compatible joint encoders.

Abstract: A method of operating a surgical system. The method includes obtaining a magnetic resonance imaging (MRI) scan in which magnetic resonance (MR) visible targets are located; registering a robotic arm to the MRI scan using a digitizing tool, the robotic arm including: multiple joints and multiple degrees of freedom; an MR-compatible structural material; multiple MR-compatible joint motors; multiple MR-compatible joint encoders; and an end effector holding an MR-compatible surgical tool having a tool tip; and displaying a location of the tool tip relative to an image from the MRI scan.
