Robotic base with controlled movement for surgical procedures
The invention involves a system and method for controlling the movements of a multi-axis robot to perform a surgery at least on the spinal area of a human in vivo. The system includes controls and software coding to cause the robot to move in desired patterns to complete the surgery, which may include bone, disc and tissue removal, and may also include insertion of hardware for fusing adjacent bony structures.
1. A robotic base for a surgical robot comprising:
a truck including a plurality of wheel assemblies rotatably mounted thereto for moving said truck on an underlying surface, said truck being adapted to have a surgical robot mounted thereon for movement therewith, at least one of the wheel assemblies including a wheel with a wheel hub and a plurality of associated rollers rotatable independently of its associated wheel hub;
a power supply mounted to the truck;
at least one motor carried by the truck and operably associated with a respective said wheel assembly and connected to the power supply; and
a first electronic controller operably connected to the motor and operable to control rotation of the wheel assemblies and effect movement of the truck along a defined path.
2. The base as set forth in claim 1 wherein there are a plurality of said at least one wheel assemblies, each with a said wheel hub and said rollers, each said wheel hub and associated rollers being associated with a respective said motor.
3. The base as set forth in claim 2 wherein there being at least four said wheel assemblies, each with a said wheel hub and said rollers.
4. The base as set forth in claim 2 including a surgical robot mounted to said truck and including an electronic controller associated therewith and operable to effect operation of the surgical robot.
5. The base as set forth in claim 4 wherein the first electronic controller and the controller associated with the robot being operably connected to one another.
6. The base as set forth in claim 4 wherein the first electronic controller and the controller associated with the robot being a single controller.
7. The base as set forth in claim 4 wherein a said wheel hub and said associated rollers being independently rotatable relative to one another and selectively driven by a single associated said motor.
8. The base as set forth in claim 4 including a suspension system associate with each of said wheel assemblies, allowing components of said truck to be supported by said wheel assemblies and move independently thereof generally vertically.
9. The base as set forth in claim 8 wherein the suspension system including a plurality of fluid cylinders each associated with a respective said wheel assembly and including a pressurized fluid source operably connected to the fluid cylinders and operable to effect selective extension and retraction of the fluid cylinders.
10. The base as set forth in claim 4 wherein said motor is coupled to a respective wheel assembly with a first drive shaft and a second drive shaft with said first drive shaft being operably coupled to a respective said wheel hub and said second shaft being operably coupled to the rollers associated with said wheel hub.
11. A method of performing a surgical procedure with a robot, the method including:
providing a truck including a plurality of wheel assemblies rotatably mounted thereto for moving said truck on an underlying surface, said truck having a surgical robot mounted thereon for movement therewith, at least one of the wheel assemblies including a wheel hub and a plurality of associated rollers rotatable independently of its associated wheel hub;
providing a power supply mounted to the truck;
providing at least one motor carried by the truck and operably associated with a respective said wheel assembly and connected to the power supply; and
providing a first electronic controller operably connected to the motor and operable to control rotation of the wheel assemblies and effect movement of the truck along a defined path and effecting movement of the truck and associated robot about a surgical area with said controller.
12. The method as set forth in claim 11 wherein there are a plurality of said at least one wheel assemblies with a said wheel hub and associated said rollers, each said wheel hub and associated rollers being associated with a respective said motor and effecting operation thereof to move the truck with said controller.
13. The method as set forth in claim 12 wherein there being at least four said wheel assemblies, each with a said wheel hub and said associated rollers and controlling operation thereof with said first electronic controller.
14. The method as set forth in claim 12 including controlling operation of said surgical robot with an electronic controller.
