Methods for performing invasive medical procedures using a surgical robot

1. A robot system comprising:

an arm coupled to a base;

a control device configured for reformatting a two-dimensional slice perpendicular to a surgical entry pathway from a computed tomography scan volume of a patient anatomy, wherein the control device is configured to define a perimeter on a pathway through the anatomy; and

wherein the arm is coupled to a tubular element configured to be placed adjacent to a target anatomy,

wherein the tubular element is moved by the arm based on a trajectory inputted into the control device,

a drill assembly positioned through the tubular element and configured to remove bone from the pathway in the intersection of the perimeter and the two-dimensional slice,

wherein the position of the drill assembly is dynamically updated continuously during the procedure and the robot arm is configured to move the drill assembly without any assistance from a surgeon,

wherein the robot system further includes a camera system that in a first position is coupled to the base and in a second position is separate and independent from the base,

wherein the camera system includes a wheel base and a plurality of wheels,

wherein the control device reformats a two-dimensional slice and iteratively moves a slice plane distally down the surgical entry pathway and distal to the tubular element as the tubular element is advanced,

wherein the slice plane is the two-dimensional slice perpendicular to the surgical entry pathway.

2. The system of claim 1 , wherein the tubular element is configured to be advanced farther into the patient after the drill assembly removes bone from the pathway.

3. The system of claim 1 , wherein the control device determines sections of bone to be drilled and soft tissue to be avoided by automatically demarcating using grayscale thresholding, and further wherein the drill assembly is controlled to drill only in the area demarcated as bone.

4. The system of claim 1 , wherein the control device is configured to identify a critical structure based on the reformatted two-dimensional slice of a CT scan loaded onto the control device.

5. The system of claim 4 , wherein a second perimeter is placed around the critical structure and loaded into the control device.

6. The system of claim 5 , the drill assembly is configured to remove bone around the second perimeter but within the first perimeter.

7. A robot system for operating on a patient comprising:

a control device having a computed tomography scan volume loaded thereon;

a tubular element configured to be placed adjacent to a target anatomical location;

a program on the control device providing a programmed route for the tubular element to travel though the patient to the target anatomical location on a display, wherein the display may manipulate the robot system; and

the tubular element is configured to be guided along the programmed route through the patient,

wherein the robot system includes an arm attached to the tubular element,

wherein the control device further includes a display for plotting routes, and configured to control the movement of the arm to position the tubular element along the programmed route,

wherein the position of the tubular element is dynamically updated continuously during the procedure and the robot system is configured to move a drill assembly without any assistance from a surgeon,

wherein the robot system further includes a camera system that in a first position is coupled to a base and in a second position is separate and independent from the base,

wherein the camera system includes a wheel base and a plurality of wheel,

wherein the control device is configured to reformat a two-dimensional slice and iteratively move a slice plane distally down the programmed route and distal to the tubular element as the tubular element is advanced,

wherein the slice plane is a two-dimensional slice from the computed tomography scan volume and is perpendicular to the programmed route.

8. The system of claim 7 , wherein the programmed route may be altered by a surgeon while the robot system is moving the tubular element through the patient.

9. The system of claim 7 , further comprising a neural sensing probe configured to be inserted into the tubular element before insertion into the patient.

10. The system of claim 9 , wherein the route may be automatically changed by the robot system based upon the neural activity sensed by the neural probe.

11. The system of claim 7 , wherein the display for plotting routes is separate from the robot system.
