Abstract

Generally, a sterile adapter for use in robotic surgery may include a frame configured to be interposed between a tool driver and a surgical tool, a plate assembly coupled to the frame, and at least one rotatable coupler supported by the plate assembly and configured to communicate torque from an output drive of the tool driver to an input drive of the surgical tool.

Claims (27)

1 . A sterile adapter for use in a robotic surgical system, the sterile adapter comprising:

a frame;

a plate assembly coupled to the frame; and

at least one rotatable coupler supported by the plate assembly and configured to rotate relative to the plate assembly and the frame, and to communicate torque from an output drive of a tool driver to an input drive of a surgical tool;

wherein the rotatable coupler is comprises a first portion configured to engage the output drive of the tool driver and a second portion configured to engage the input drive of the surgical tool.

2 . The sterile adapter of claim 1 , wherein the first portion comprises a first face having a first engagement feature, and the second portion comprises a second face having a second engagement feature comprising a different shape than the first engagement feature.

3 . The sterile adapter of claim 2 , wherein at least one of the first or second engagement features comprises an arcuate feature to provide a single rotational alignment relative to an output drive disc on the tool driver and relative to an input drive disc on the surgical tool.

4 . The sterile adapter of claim 2 , wherein the first engagement feature and the second engagement feature extend in opposite axial directions.

5 . The sterile adapter of claim 4 , wherein the first engagement feature comprises an arcuate recess and the second engagement feature comprises a recess substantially centered on an axis of rotation of the rotatable coupler.

6 . The sterile adapter of claim 1 , wherein the rotatable coupler comprises an outer flange.

7 . The sterile adapter of claim 6 , wherein the plate assembly includes a first plate and a second plate, and the outer flange of the rotatable coupler is disposed between the first plate and the second plate.

8 . The sterile adapter of claim 1 , wherein the first portion comprises a first face having a plurality of first drive features configured to engage driving features of the output drive of the tool driver, and the second portion comprises a second face having a plurality of second drive features configured to engage driven features of the input drive of the surgical tool.

9 . The sterile adapter of claim 8 , wherein the plurality of first drive features and the plurality of second drive features are equidistant from an axis of rotation.

10 . The sterile adapter of claim 9 , wherein the plurality of first drive features and the plurality of second drive features are rotationally offset from each other.

11 . The sterile adapter of claim 10 , wherein the plurality of first drive features and the plurality of second drive features are rotationally offset from each other by about 90 degrees.

12 . The sterile adapter of claim 1 , wherein the frame defines a generally planar opening and the plate assembly is movable within the opening.

13 . The sterile adapter of claim 1 , wherein the frame is configured to couple to a sterile drape.

14 . A drive coupler for communicating torque from a tool driver to a surgical tool, the drive coupler comprising:

a rotatable body configured to be interposed between an output drive of the tool driver and an input drive of the surgical tool, wherein the rotatable body comprises:

a first portion having a first engagement feature and a first drive feature for engaging with the output drive of the tool driver; and

a second portion having a second engagement feature and a second drive feature for engaging with the input drive of the surgical tool.

15 . The drive coupler of claim 14 , wherein the first and second portions are defined by a first face and a second face of the rotatable body, respectively, and the first and second engagement features are recesses having different shapes and extending in opposite axial directions.

16 . The drive coupler of claim 14 , wherein the first and second portions are defined by a first face and a second face of the rotatable body, respectively, the first engagement feature comprises an arcuate channel and the second engagement feature is substantially centered on an axis of rotation of the rotatable coupler.

17 . The drive coupler of claim 14 , wherein the body comprises an outer flange.

18 . The drive coupler of claim 14 , wherein the first drive feature comprises a first set of pin holes and the second drive feature comprises a second set of pin holes that are equidistant from an axis of rotation.

19 . The drive coupler of claim 18 , wherein the first set of pin holes and the second set of pin holes are rotationally offset from each other.

20 . The drive coupler of claim 19 , wherein the first set of pin holes and the second set of pin holes are rotationally offset from each other by about 90 degrees.
