Abstract

A coupling device is described herein for coupling two objects. The coupling device includes a body having a receiving member, a bore, and a locking pin situated inside the bore. The locking pin is translatable beyond the bore to intercept a portion of an attachment region of an object to removably couple the object to the coupling device. A lever connected to the locking pin allows a user to rotate the locking pin. Upon rotation of the lever, components in the body cause the locking pin to rotate and translate towards the object to intercept the portion of the attachment region of the object.

First claim

The invention claimed is:

1. A coupling device, comprising:
a body comprising:
a receiving member adapted to be removably coupled with an attachment region of a separate first object; and
a bore located within a portion of the body;

a locking pin positioned in the bore and axially translatable beyond the bore to intercept a portion of the attachment region when the attachment region is coupled to the receiving member; and
a lever for rotating the locking pin.

2. The coupling device of claim 1 wherein the receiving member further comprises a support for mating with the attachment region.

3. The coupling device of claim 2 wherein the support is a dovetail joint comprising an opening and a stop portion.

4. The coupling device of claim 1 wherein the body further comprises a slot extending from the bore to an outer surface of the body, wherein the lever fits within the slot.

5. The coupling device of claim 1 wherein the locking pin further comprises one or more pins, and wherein the coupling device further comprises a lid having a plurality of grooves that interact with the one or more pins to cause the locking pin to translate beyond the bore when the locking pin is rotated.

6. The coupling device of claim 5 wherein the grooves have an undulating surface.

7. The coupling device of claim 1 wherein the first object comprises at least one of a tool or a workpiece.

8. The coupling device of claim 1 wherein the locking pin further comprises a cam at a distal end of the shaft.

9. A system, comprising:
a first object; and
the coupling device of claim 1 mounted to a portion of the first object.

10. The system of claim 9 wherein the first object is a surgical robot.

11. The system of claim 9 further comprising a second object having an attachment region for removably coupling the second object to the coupling device.

12. The system of claim 11 wherein the attachment region comprises an interaction bore that interacts with the locking pin.

13. The system of claim 11 wherein the second object comprises at least one of a tool or a workpiece.

14. A coupling device, comprising:
a body comprising:
a receiving member adapted to be removably coupled with an attachment region of a separate first object; and
a bore located within a portion of the body;

a locking pin positioned in the bore and axially translatable beyond the bore to intercept a portion of the attachment region when the attachment region is coupled to the receiving member; and
wherein the locking pin further comprises a shaft and a plurality of teeth radially positioned on an outer surface of the shaft, wherein one or more pawls engage one or more teeth of the plurality of teeth.

15. The coupling device of claim 14 further comprising a pawl release mechanism for disengaging the one or more pawls from the one or more teeth.

16. The coupling device of claim 15 wherein the pawl release mechanism comprises one or more openings for receiving a portion of the one or more pawls, respectively, and a release lever.

17. The coupling device of claim 14 further comprising a lever for rotating the locking pin.

18. A coupling device, comprising:
a body comprising:
a receiving member adapted to be removably coupled with an attachment region of a separate first object; and
a bore located within a portion of the body;

a locking pin positioned in the bore and axially translatable beyond the bore to intercept a portion of the attachment region when the attachment region is coupled to the receiving member; and
a mounting member adapted to mount the coupling device to a portion of a surgical robot.

19. The coupling device of claim 18 wherein the mounting member is located on a first side of the body and the receiving member is located on an opposing side of the body.

20. The coupling device of claim 18 further comprising a lever for rotating the locking pin.
