Abstract

A medical device support system adapter for connection to a load balancing arm of a medical device support system. The adapter includes a body having a central axis, a connection component at one end of the body and an interface at an opposite end of the body. The body is rotatably connectable to another component of the medical device support system. The interface is connectable to a hub of the load balancing arm of the medical device support system. The interface has at least two mounting bolt holes equally angularly spaced apart about the central axis such that the body is connectable to the hub of the load balancing arm in at least two different angular positions of the body about the central axis.

First claim

What is claimed is:

1. A medical device support system adapter for connection to a load balancing arm of a medical device support system, comprising:
a body having a central axis;
a connection component at one end of the body that is rotatably connectable about the central axis to another component of the medical device support system;
an interface at an opposite end of the body that is connectable to a hub of the load balancing arm of the medical device support system;
wherein the interface has at least two mounting bolt holes equally angularly spaced apart about the central axis such that the body is connectable to the hub of the load balancing arm in at least two different angular positions of the body about the central axis;
further comprising an annular protuberance that is mateable with a corresponding annular protuberance of the hub to axially align the adapter with the hub;
wherein the annular protuberance of the adapter projects axially from the interface either to form an annular convex section or an annular concave section that is mateable with the corresponding annular protuberance of the hub.

2. The medical device support system adapter of claim 1 , wherein the connection component includes a drop tube that is rotatably connectable to a support structure of the medical device support system.

3. The medical device support system adapter of claim 1 , wherein the connection component includes a bearing support that is rotatably connectable to an accessory of the medical device support system.

4. The medical device support system adapter of claim 1 , wherein the at least two mounting bolt holes are on a bolt circle having the central axis as its center.

5. The medical device support system adapter of claim 1 , wherein the at least two mounting bolt holes include mounting bolt clearance holes.

6. The medical device support system adapter of claim 5 , wherein the mounting bolt clearance holes are counterbored.

7. The medical device support system adapter of claim 1 , wherein the annular structures are circular shape.

8. The medical device support system adapter of claim 1 , further comprising at least one rotational stop protruding from a portion of the one end and radially offset from the central axis.

9. The medical device support system adapter of claim 1 , wherein the interface has four mounting bolt holes equally angularly spaced apart about the central axis 90 degrees apart such that the body is connectable to the hub of the load balancing arm in four different angular positions of the body about the central axis.

10. An adapter for a load balancing arm of a medical device support system, the adapter including:
a body having a central axis;
a drop tube at one end of the body that is rotatably connectable to a support structure of the medical device support system;
at least one rotational stop protruding from a portion of the one end and radially offset from the central axis; and,
an interface at an opposite end of the body that is connectable to a hub of the load balancing arm;
wherein the drop tube includes a spindle with a circular groove to radially receive a retaining clip to axially support the drop tube.

11. The adapter of claim 10 , wherein the interface has at least two mounting bolt holes equally angularly spaced apart about the central axis such that the body is connectable to the hub of the load balancing arm in at least two different angular positions of the body about the central axis.

12. The adapter of claim 11 , wherein the at least two mounting bolt holes are on a bolt circle having the central axis as its center.

13. The adapter of claim 11 , wherein the rotational stop is angularly offset from the at least two mounting bolt holes.

14. The adapter of claim 10 , in combination with a support structure of a medical device support system, wherein the support structure includes a horizontal extension arm, and wherein the drop tube is rotatably connectable to a knuckle joint assembly of the horizontal extension arm.

15. An adapter for a load balancing arm of a medical device support system, the adapter including:
a body having a central axis;
a bearing support at one end of the body that is rotatably connectable to an accessory of the medical device support system;
at least one rotational stop protruding from a portion of the one end and radially offset from the central axis; and
an interface at an opposite end of the body that is connectable to a hub of the load balancing arm;
wherein the body includes a radial groove to radially receive a retaining clip to axially support the accessory.

16. The adapter of claim 15 , wherein the interface has at least two mounting bolt holes equally angularly spaced apart about the central axis such that the body is connectable to the hub of the load balancing arm in at least two different angular positions of the body about the central axis.

17. The adapter of claim 16 , wherein the at least two mounting bolt holes are on a bolt circle having the central axis as its center.

18. The adapter of claim 16 , wherein the rotational stop is angularly offset from the at least two mounting bolt holes.

19. The adapter of claim 15 , in combination with an accessory of a medical device support system, wherein the accessory includes an accessory spindle, and wherein the bearing support is rotatably connectable to the accessory spindle of the accessory.

20. An interchangeable load balancing arm assembly for a medical device support system, comprising:
a load balancing arm having at least one hub; and,
a plurality of interchangeable adapters that are attachable and detachable to the hub, wherein each of the plurality of interchangeable adapters includes a connection component having an associated connection component diameter and being rotatably connectable about an axis of rotation to another component of the medical device support system;
wherein the plurality of interchangeable adapters have different axial lengths and/or different associated connection component diameters;
wherein the load balancing arm includes a counterbalancing arm;
wherein the at least one hub includes a proximal hub and a distal hub at opposite ends of the counterbalancing arm, and the plurality of interchangeable adapters includes a plurality of interchangeable drop tube adapters that are attachable and detachable to the proximal hub and a plurality of interchangeable bearing support adapters that are attachable and detachable to the distal hub.

21. The interchangeable load balancing arm assembly of claim 20 , wherein each of the plurality of adapters includes a body having a central axis, wherein the connection component is provided at one end of the body and an interface is provided at an opposite end of the body, the plurality of adapters being attachable and detachable to the hub of the load balancing arm via the interface.

22. The interchangeable load balancing arm assembly of claim 21 , wherein the interface has at least two mounting bolt holes equally angularly spaced apart about the central axis such that the body is connectable to the hub of the load balancing arm in at least two different angular positions of the body about the central axis.
