Abstract

A robotic medical system includes a post being substantially vertical and coupled to a base; a robotic drive having a socket for receiving the post; and at least one tapered interface shaped and oriented to engage the socket to prevent rotation of the robotic drive about at least one axis.

First claim

We claim:

1. A robotic medical system, comprising:
a post being substantially vertical and coupled to a base;
a robotic drive having a socket for receiving the post; and
a first tapered key integrated with the post and oriented to engage the socket, the first tapered key comprising a first substantially vertical surface and a first sloped surface opposing the first substantially vertical surface in a first rotational direction about a vertical axis of the post;
a second tapered key integrated with the post and oriented to engage the socket, the second tapered key comprising a second substantially vertical surface and a second sloped surface opposing the second substantially vertical surface in a second rotational direction about the vertical axis of the post;
wherein the first substantially vertical surface and the second substantially vertical surface resist rotation of the robotic drive about at least the vertical axis of the post when engaged with the socket.

2. The robotic medical system of claim 1 , wherein the post is substantially cylindrical and the tapered keys are positioned about 180 degrees apart along a circumference of the post.

3. The robotic medical system of claim 1 , wherein the socket includes tapered cavities shaped and positioned to receive the first tapered key and the second tapered keys and cause physical engagement of the post and the robotic drive.

4. The robotic medical system of claim 1 , wherein the post includes at least one insertion interface to facilitate insertion of the post into the socket.

5. The robotic medical system of claim 4 , wherein the post is a cylinder and the insertion interface includes at least one cylindrical portion along a length of the post, the cylindrical portion being configured to engage an internal bushing of the socket.

6. The robotic medical system of claim 5 , wherein the at least one cylindrical portion includes multiple cylindrical portions spaced along the length of the post.

7. The robotic medical system of claim 6 , wherein the multiple cylindrical portions have progressively smaller diameters along the length of the post.

8. The robotic medical system of claim 4 , wherein the insertion interface includes a convex tip at a termination of the post.

9. The robotic medical system of claim 1 , wherein each of the first tapered key and the second tapered key extend from a conical portion of the post to an outer periphery of a base portion of the post.

10. The robotic medical system of claim 1 , wherein the post has a cross-sectional shape selected from one of circular, oval, or polygonal.

11. A robotic medical system, comprising:
a positioning system coupled to a base, the positioning system including a substantially vertical post; and
a robotic drive having a socket for receiving the post,
wherein the post includes at least two tapered keys to engage the socket, each tapered key positioned at a bottom end of the post and comprising a substantially vertical surface and a sloped surface opposing the substantially vertical surface in a rotational direction about a vertical axis of the post, the substantially vertical surfaces being oriented in an opposing manner to resist rotation of the robotic drive about at least the vertical axis.

12. The robotic medical system of claim 11 , wherein the socket includes tapered cavities for receiving the tapered keys to cause physical engagement of the post and the socket.

13. The robotic medical system of claim 11 , wherein the post includes at least one insertion interface to facilitate insertion of the post into the socket.

14. The robotic medical system of claim 13 , wherein the insertion interface includes at least one cylindrical portion along a length of the post, the cylindrical portion being configured to engage an internal bushing provided in the socket.

15. The robotic medical system of claim 13 , wherein the insertion interface includes a convex tip at a termination of the post.
