Abstract

A medical navigation system is provided having a positioning device having a positioning arm with a flange at the end of the positioning arm, a controller at least electrically coupled to the positioning device, and an end effector joystick controller for connecting to the flange of the positioning arm. The controller has a processor coupled to a memory and a display. The end effector joystick controller includes a mating component for connecting to the flange of the positioning arm, and a joystick portion extending from the mating component.

First claim

I claim:

1. An end effector controller for connecting to and controlling a positioning arm of a positioning device, the end effector controller comprising:
a mating component for connecting to a flange of the positioning arm; and
a handle portion extending from the mating component, the handle portion comprising:
a puck-shaped handle;
a housing portion attached within the handle and attached to the mating component; and

a 6 degrees of freedom (6DOF) sensor system housed in the housing portion and connected to the handle, the sensor system being configured to sense both translation and rotation in all of the X direction, the Y direction and the Z direction.

2. The end effector controller according to claim 1 , further comprising:
a second mating component attached to the first mating component, the second mating component for connecting to an end effector.

3. The end effector controller according to claim 2 , wherein the second mating component includes a rigid support member.

4. The end effector controller according to claim 3 , wherein the rigid support member passes through holes formed in the handle.

5. The end effector controller according to claim 4 , wherein a plurality of rigid support members each passes through a corresponding hole in the handle.

6. The end effector controller according to claim 1 , wherein the mating component and the handle portion are axially aligned.

7. The end effector controller according to claim 1 , wherein the mating component is adapted to connect to the flange of the positioning arm with a dowel pin and is adapted to be secured with at least one screw.

8. A medical navigation system, comprising:
a positioning device having a positioning arm with a flange at an end of the positioning arm;
a controller at least electrically coupled to the positioning device, the controller having a processor coupled to a memory and a display; and
an end effector controller for connecting to the flange of the positioning arm, the end effector controller comprising:
a mating component for connecting to the flange of the positioning arm; and
a handle portion extending from the mating component, the handle portion comprising:
a puck-shaped handle;
a housing portion attached within the handle and attached to the mating component; and
a 6 degrees of freedom (6DOF) sensor system housed in the housing portion and connected to the handle, the sensor system being configured to sense both translation and rotation in all of the X direction, the Y direction and the Z direction.

9. The medical navigation system according to claim 8 , the end effector controller further comprising:
a second mating component attached to the first mating component, the second mating component for connecting to an end effector.

10. The medical navigation system according to claim 9 , wherein the second mating component includes a rigid support member.

11. The medical navigation system according to claim 10 , wherein the rigid support member passes through a hole formed in a handle.

12. The medical navigation system according to claim 11 , wherein there is a plurality of rigid support members each passing through a corresponding hole in the handle.

13. The medical navigation system according to claim 8 , wherein the mating component and the handle portion are axially aligned.

14. The medical navigation system according to claim 8 , wherein the mating component is adapted to connect to the flange of the positioning arm with a dowel pin and is adapted to be secured with at least one screw.
