Abstract

A sterile barrier is provided for use with a surgical robotic system. The sterile barrier can include a housing configured to mate with a tool driver mated to a robotic arm and to removably receive a surgical tool. The housing of the sterile barrier has a sterile flexible fabric extending therefrom such that the housing and the flexible fabric are formed in more than one plane and define a sterile side on which the surgical tool is disposed and a non-sterile side on which the tool driver and the robotic arm are disposed. The housing has an opening for receiving the surgical tool. The housing can have at least one electrical contact configured to operably mate with at least one complementary electrical contact on at least one of the tool driver and the robotic arm.

Claims

1. A sterile barrier for use with a robotic surgical system, comprising:

a housing configured to mate with a tool driver mated to a robotic arm and to removably receive a surgical tool, the housing having a sterile flexible fabric extending therefrom such that the housing and the flexible fabric are formed in more than one plane and define a sterile side on which the surgical tool is disposed and a non-sterile side on which the tool driver and the robotic arm are disposed, the housing further having a substantially rigid, generally cylindrical elongate member and a substantially c-shaped cross section, and the housing further having

an opening for receiving the surgical tool, and

at least one electrical contact configured to operably mate with at least one electrical contact on at least one of the tool driver and the robotic arm.

2. The surgical system of claim 1, wherein the housing has a first side that is configured to be received within and mate with an opening in the tool driver and a second side, opposite the first side.

3. The surgical system of claim 1, wherein the housing opening is an elongate slit.

4. The surgical system of claim 1, wherein the housing is formed of an annular rim, a first section, and a second section, the annular rim is configured to attach the sterile flexible fabric therefrom such that an exterior portion of the housing defines the sterile side and an interior portion of the housing defines the non-sterile side, the first section having at least one electrical contact to operably mate with at least one electrical contact on at least one of the tool driver and the robotic arm, and the second section having a nominal diameter less than the first section to receive an interchangeable shaft coupled to the surgical tool.

5. The surgical system of claim 1, wherein the sterile flexible fabric comprises a polymeric of an elastic membrane.

6. The surgical system of claim 1, wherein the electrical contacts on a portion of the surgical tool are formed on a puck portion of the surgical tool.

7. The sterile barrier of claim 1, wherein the housing opening is formed on a first side of the housing.

8. The sterile barrier of claim 1, wherein the housing further includes a first tool region having a first width adjacent to a second tool region having a second width.

9. A sterile barrier for use with a robotic surgical system, comprising:

a housing having a substantially c-shaped cross-section and configured to mate with a tool driver mated to a robotic arm and to removably receive a surgical tool, the housing including;

an annular rim disposed on a first end of the housing;

a sterile flexible fabric coupled to the housing such that the housing and the sterile flexible fabric are formed in more than one plane; and

a first section adjacent to the annular rim and having a substantially c-shaped cross section and at least one electrical contact configured to operably mate with at least one electrical contact on at least one of the tool driver and the robotic arm.

10. The sterile barrier of claim 9, wherein the first section further includes at least one slot configured to mate with a portion of a surgical tool.

11. The sterile barrier of claim 9, wherein the housing further includes a second section proximate to the first section, the second section configured to receive a shaft of the surgical tool.

12. The sterile barrier of claim 9, wherein the housing further includes an opening formed on a first side of the housing.

13. The sterile barrier of claim 9, wherein the housing further includes a first tool region having a first width adjacent to a second tool region having a second width.
