Systems and methods for monitoring an operative site during a surgical procedure using a computer controlled surgical device. In general, the methods include the steps of processing one or more defined cutting paths having one or more cut regions; determining a correlation between the cut region and one or more critical regions to generate an alert, wherein the alert indicates a movable end-effector is within a defined proximity of the critical region; and requiring a user acknowledgment of the alert to allow processing of the cutting path to continue. Also described herein are systems and methods for minimizing user fatigue during a semi-computer controlled surgical procedure. In general, the methods includes the step of requiring a user generated acknowledgment in response to a computer generated alert, wherein the user acknowledgment is generated using a user controller, the user controller being minimally intrusive to the user experience.

Systems and methods for monitoring a surgical procedure with critical regions

A system and a device are provided for counterbalancing a surgical robotic system that include a rail assembly having a shaft that engages a first carriage and a second carriage via threaded mechanism. A manipulatable arm carries a movable effector; the manipulatable arm is supported by the first carriage. A counter weight is supported by the second carriage with a single actuator. A simplified robotic surgery system results.

Described herein are systems and devices for counterbalancing a surgical robotic system using a counterbalanced Z-axis drive. The counterbalanced Z-axis drive includes a self-centering ball screw assembly having a linear actuator and a counter weight. The counter weight is configured to substantially support a load associated with an arm of the robotic system when the driving portion is engaged or disengaged. In some embodiments, the counterbalanced Z-axis drive controls the arm and a movable effector mounted on the arm. Also disclosed herein are systems and devices for direct drive actuation of rotary axes of the arm which reduce the size and weight of the arm.
