1. A method of performing surgery with a robotic surgical system, the method comprising:
- moving a mobile cart transporting a robotic surgical system comprising a robotic arm in proximity to an operating table, wherein the robotic arm has an end effector comprising a surgical instrument guide attached thereto, the surgical instrument guide configured to hold and/or restrict movement of a surgical instrument therethrough;
stabilizing the mobile cart;
maneuvering the robotic arm to a desired position to align an axis defined by the instrument guide at a desired trajectory in relation to a patient situation, wherein the surgical instrument guide comprises a rigid hollow tubular structure having a first open end and a second open end, said structure defining the axis along which movement of a surgical instrument sliding through the structure is restricted;
fixing the position of the robotic arm; and
maneuvering the surgical instrument in a manner that is constrained by the surgical instrument guide, wherein;
the surgical instrument is fitted with a tool support shaped and sized to slide through the surgical instrument guide along the axis defined by the guide,the tubular structure of the surgical instrument guide has an interior surface shaped and sized to accommodate the tool support sliding through the guide such that movement of the tool support is constrained in all directions except along the axis defined by the guide, andthe tubular structure comprises a longitudinal notch along its length, wherein the longitudinal notch is sized to (i) permit a marker attached to the tool support to be viewable by a navigation camera along an entire range of movement of the tool support through the guide, (ii) constrain movement of the navigation marker in a fixed orientation along the axis defined by the guide, and (ii) permit the tool support to slide along the axis defined by the guide while the guide is held in a fixed position by the robotic surgical system.

Abstract
Described herein is a surgical instrument guide for use with a robotic surgical system, for example, during spinal surgery. In certain embodiments, the guide is attached to or is part of an end effector of a robotic arm, and provides a rigid structure that allows for precise preparation of patient tissue (e.g., preparation of a pedicle) by drilling, tapping, or other manipulation, as well as precise placement of a screw in a drilled hole or affixation of a prosthetic or implant in a prepared patient situation.
