Abstract

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.

First claim

What is claimed is:

1. A medical robot system comprising:
a body;
a computer processor disposed within the body;
a tool assembly attached to the body;
a display assembly attached to the body;
a base attached to the body; and
at least one stabilizer wheel assembly disposed on the base,
wherein each stabilizer wheel assembly comprises a motor and a stabilizer leg, and
wherein the computer processor is configured to receive one or more commands from a platform interface to move each stabilizer leg by controlling each motor
wherein each stabilizer wheel assembly comprises a foot attached to an end of the corresponding stabilization leg opposite a nut.

2. The medical device of claim 1 , wherein the computer processor is configured to drive each stabilization leg into a contact surface until each stabilization leg exerts a predetermined force on the contact surface.

3. The medical device of claim 2 , wherein each stabilizer wheel assembly further comprises a caster.

4. The medical device of claim 3 , wherein each stabilizer wheel assembly further comprises a stem, wherein the corresponding caster rotates three hundred and sixty degrees around each stem.

5. The medical device of claim 4 , wherein each motor is connected to a top of the corresponding stem.

6. The medical device of claim 5 , wherein each stabilization leg is configured to extend through the corresponding caster to the contact surface.

7. The medical device of claim 1 , wherein each stabilizer wheel assembly further comprises a motor cover that encloses each motor, a motor cap disposed on top of each motor, and a motor bracket that supports each motor.

8. The medical device of claim 1 , wherein each foot increases the friction between the corresponding stabilization leg and a contact surface.

9. The medical device of claim 8 , wherein each stabilizer wheel assembly further comprises a caster and a set screw is disposed on a side of the caster.

10. The medical device of claim 9 , wherein the set screw of each stabilizer wheel assembly is secured into a corresponding channel to prevent the corresponding stabilization leg from rotating.

11. The medical device of claim 1 , wherein each stabilizer wheel assembly further comprises a bumper.

12. A medical robot system comprising:
a body;
a stabilizer wheel assembly coupled to the body, wherein the stabilizer wheel assembly comprises a motor assembly and stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body; and
a computer processor disposed within the body, wherein the computer processor is configured to receive one or more commands from a platform interface to move each stabilizer leg by controlling each motor
wherein the stabilizer wheel assembly comprises a foot attached to an end of the stabilization leg opposite a nut.

13. The medical device of claim 12 , wherein the computer processor is configured to drive the stabilization leg into the contact surface until the stabilization leg exerts a predetermined force on the contact surface.

14. The medical device of claim 13 , wherein the stabilizer wheel assembly further comprises a caster.

15. The medical device of claim 14 , wherein the stabilizer wheel assembly further comprises a stem, wherein the caster rotates three hundred and sixty degrees around the stem.

16. The medical device of claim 15 , wherein the motor assembly is connected to a top of the stem.

17. The medical device of claim 16 , wherein the stabilization leg is configured to extend through the caster to the contact surface.

18. The medical device of claim 12 , wherein the motor assembly further comprises a motor, a motor cover that encloses each motor, a motor cap disposed on top of each motor, and a motor bracket that supports each motor.
