Abstract: Surgical systems and methods involve a robotic arm with a first mounting portion that releasably receives a sterile barrier assembly and a second mounting portion associated with a surgical component. An illumination device is coupled to the robotic arm. Controller(s) detect, using one or more sensors, a condition associated with installation of one or more of the sterile barrier assembly and the second mounting portion to the first mounting portion. The controller(s) control the illumination device to indicate the condition to a user.

Abstract: Surgical systems and methods involve a robotic manipulator with a force sensor and a surgical tool that holds a screw. The screw has a known thread geometry. A navigation system tracks a pose of a target anatomy. Controller(s) store the known thread geometry and control the robotic manipulator to maintain the rotational axis on a planned trajectory with respect to the target anatomy based on the tracked pose of the target anatomy. The controller(s) detect, with the force sensor, a force applied by a user. The controller(s) control a rotational rate of the surgical tool to rotate the screw about a rotational axis and an advancement rate of the surgical tool to linearly advance the screw along the planned trajectory. The rotational rate and the advancement rate are based on the force applied by the user and are proportional to the known thread geometry.

Abstract: Surgical systems and methods involving a reamer tool and a surgical robotic arm. The reamer tool has a shaft, a tool engagement surface coupled to the shaft, and a reamer head attached to the shaft. The surgical robotic arm supports a guide that can receive the reamer tool. The guide has a pair of arms, each arm extending to an arm end and the arm ends being spaced apart from one another to provide an opening between the arm ends. A channel is formed between the arms. The guide enables a portion of the shaft to move through the opening between the arm ends such that the shaft portion can enter and exit the channel. The arms define a guide engagement surface that is arc-shaped and that enables contact with the tool engagement surface to facilitate alignment of the reamer tool and the guide.

Abstract: An assembly for a surgical arm includes a tool to position a prosthesis and an end effector. The tool has a tool shaft extending along a tool axis and a tool engagement surface. The end effector has a mount attachable to the surgical arm, a body portion extending from the mount, a distal end, and a guide portion is at the distal end of the body portion to receive the tool. The guide portion has a pair of arms, each arm extending to an arm end and the arm ends are spaced apart from one another to provide an opening between the arm ends. A channel is formed between the arms and extends along a guide axis. The arms define an arc-shaped guide engagement surface to enable contact with the tool engagement surface for facilitating alignment of the tool axis and the guide axis.

Abstract: A robotic system and methods for performing spine surgery are disclosed. The system comprises a robotic manipulator with a tool to hold a screw and to rotate the screw about a rotational axis. The screw is self-tapping and has a known thread geometry that is stored by one or more controllers. A navigation system tracks a position of a target anatomy. Movement of the robotic manipulator is controlled to maintain the rotational axis of the surgical tool along a planned trajectory with respect to the target anatomy based on the tracked position of the target anatomy. In autonomous or manual modes of operation, the rotational rate of the screw about the rotational axis and/or an advancement rate of the screw linearly along the planned trajectory is controlled to be proportional to the known thread geometry stored in the memory.
