Abstract

An adapter plate assembly which provides a convenient interface between a mounting support assembly for suspending an instrument driver robotic instrument system above a operating table. The adapter plate securely mounts to the operating table, and may be adjustable so that it can be adjusted to fit various sizes and models of operating tables. The adapter plate assembly comprises a main plate which rests on the surface of the operating table. A first clamp assembly which removably attaches to the operating table is mounted on one or more horizontal adjustment rods which are slidably received in one of the main plate in order to provide adjustability to the width of the adapter plate assembly. On the opposing end of the main plate, a second clamp assembly is coupled main plate. In order to secure the support assembly of a robotic instrument system, an adapter rail is also coupled to the main plate. The adapter rail is configured to detachably couple to a support assembly interface of the support assembly, and provides sufficient structural support for suspending the instrument driver above the operating table.

Claims

1. An adapter plate assembly for mounting a support assembly used for suspending an instrument driver above an operating table, comprising:

a substantially flat main plate having top and bottom surfaces, first and second ends, and two sides;

a first clamp assembly coupled to the first end of the main plate and having a first clamp configured for removable attachment to the operating table, the first clamp assembly being extendable from the main plate first end so as to allow for adjusting a width of the adapter plate assembly to accommodate a width of the operating table, the first clamp assembly having a first split clamp which releasably couples to a first vertical adjustment rod, wherein the first split clamp may be released to allow the position of the first clamp assembly to be adjusted vertically along the first adjustment rod to adjust a respective height of the first clamp relative to the top surface of the main plate, and wherein the first split clamp can be tightened to secure the first split clamp to the first adjustment rod;

a second clamp assembly coupled to the second end of the main plate and having a second clamp configured for removable attachment to the operating table, the second clamp assembly having a second split clamp which releasably couples to a second vertical adjustment rod, wherein the second split clamp may be released to allow the position of the second clamp assembly to be adjusted vertically along the second adjustment rod to adjust a respective height of the second clamp relative to the top surface of the main plate, and wherein the second split clamp can be tightened to secure the second split clamp to the second adjustment rod; and

an adapter rail coupled to the second end of main plate, the adapter rail configured to detachably couple to a support assembly interface and provide sufficient structural support for suspending the instrument driver above the operating table.

2. The adapter plate assembly of claim 1, wherein the first clamp assembly is mounted on an adjustment rod which is slidably received in the main plate and configured to allow the first clamp to be extended and retracted from the main plate so as to adjust the width of the adapter plate assembly to accommodate the width of the operating table, and further comprising a locking device for securing the adjustment rod in a desired position.

3. The adapter plate assembly of claim 1, wherein the first clamp assembly is mounted on a horizontal adjustment rod which is slidably received in the main plate, the adjustment rod configured to allow the first clamp to be extended and retracted from the main plate so as to adjust the width of the adapter plate assembly to accommodate the width of the operating table, and further comprising a first locking device for securing the horizontal adjustment rod in a desired position, the first split clamp and second split clamp each comprise a threaded set knob which passes through a through-hole in one side of the respective clamp and threads into the other side so that when the thread set knob is tightened, the split clamp closes, decreasing its inner diameter and locking it onto the respective vertical adjustment rod.

4. The adapter plate assembly of claim 1, wherein the first clamp assembly and the second clamp assembly each comprises:

an L-shaped clamp body configured to engage a table rail of the operating table;

a first set screw threaded through the clamp body and configured to tighten directly against the table rail; and

a second set screw threaded through the clamp at an angle to said first set screw and configured to engage the underside of the table rail.

5. The adapter plate assembly of claim 1, wherein the adapter plate assembly is configured to mount to a top side of the operating table.

6. The adapter plate assembly of claim 1, wherein the adapter plate assembly is configure to mount to a bottom side of the operating table.

7. The adapter plate assembly of claim 1, wherein the adapter rail is configured to detachably couple to two or more support assembly interfaces in order to support two or more support assemblies.

8. The adapter plate assembly of claim 1, further comprising a second adapter rail coupled to the second end of the main plate, the second adapter rail configured to detachably couple to a second support assembly interface.

9. An adapter plate assembly for mounting a support assembly for suspending a medical instrument driver above a operating table, comprising:
