Abstract

A medical robot system, including a robot coupled to an effectuator element with the robot configured for controlled movement and positioning. The system may include a transmitter configured to emit one or more signals, and the transmitter is coupled to an instrument coupled to the effectuator element. The system may further include a motor assembly coupled to the robot and a plurality of receivers configured to receive the one or more signals emitted by the transmitter. A control unit is coupled to the motor assembly and the plurality of receivers, and the control unit is configured to supply one or more instruction signals to the motor assembly. The instruction signals can be configured to cause the motor assembly to selectively move the effectuator element.

First claim

What is claimed is:

1. A surgical robot system comprising:
a robot base having a display and a computer;
a robot arm coupled to the robot base, wherein movement of the robot arm is electronically controlled by the robot base; and
a first end-effectuator, coupled to the robot arm, containing a post and a targeting fixture attached to the post;
wherein the display is configured to indicate a location of the first end-effectuator in relation to at least one of the robot base and the robot arm, and
wherein the first end-effectuator is configured to be removable from the robot arm and the robot arm is configured to receive a second end-effectuator,
wherein optical markers are mounted on an x-axis of the robot base so that the computer is configured to calculate the orientation and position of the first end effectuator based on a position of the optical markers on the robot base and the targeting fixture,
wherein the robot arm is configured to independently move the first or second end effectuator along the x, y, and z axes and configured for selective rotation about one of the x, y, and z axes, and wherein the robot arm does not provide six degrees of freedom,
wherein movements of the robot arm in the x, y, and z axes are independent of one another and adapted to move in a cartesian positioning system.

2. The surgical robot system of claim 1 , further comprising one or more cameras for tracking the targeting fixture.

3. The surgical robot system of claim 2 , wherein the first and second end-effectuators are configured to snap-in at an end of the robot arm.

4. The surgical robot system of claim 1 , wherein the first and second end effectuators each contain identification circuitry and wherein the computer is configured to apply a stored calibration setting in response to recognizing the identification circuitry.

5. The surgical robot system of claim 4 , wherein the targeting fixture comprises one or more active markers.

6. The surgical robot system of claim 1 , wherein the display is configured to show positioning of the first end-effectuator in relation to a patient.

7. The surgical robot system of claim 1 , further comprising a surgical instrument connected to the first end-effectuator, and wherein the display is configured to show a graphical representation of the surgical instrument relative to a patient.
