Abstract

A surgical fluid manager includes a pump releasably engageable to tubing and a user interface. The user interface is configured to enable finger-touch selection of a fluid flow rate through the tubing and configured to operate in at least one of a first mode or a second mode. In the first mode, the flow rate is controlled via direct selection of one of a plurality of selectable digital numeric values, while in the second mode the flow rate is controlled via user selection of one alphanumeric identifier within a scale of alphanumeric identifiers. Each respective alphanumeric identifier directly corresponds to just one instrument size within a scale of instrument sizes.

Claims

1-18. -18. (canceled)

19. A surgical fluid manager comprising:

a positive displacement pump releasably engageable to tubing; and

a user interface configured to enable electronic finger-touch selection of a fluid flow rate through the tubing and through a first surgical instrument connectable to the tubing, wherein the user interface is configured to convertibly operate between;

a first mode configured to directly control the flow rate via user selection of one of a plurality of displayable, selectable digital numeric values;

or

a second mode configured to directly control the flow rate via user selection of one alphanumeric size identifier within a scale of displayable alphanumeric size identifiers, wherein each respective alphanumeric size identifier directly corresponds to just one surgical instrument size within a scale of different surgical instrument sizes, and wherein the different surgical instrument sizes relate to substantially the same type of surgical instrument, including the first surgical instrument.

21. The surgical fluid manager of claim 19 wherein the respective surgical instrument sizes are determined by a cross-sectional area of a respective one of the surgical instruments and wherein each respective surgical instrument includes an irrigation conduit through which the fluid flows.

22. The surgical fluid manager of claim 19 wherein the user interface comprises:

a console positionable external to a sterile field and supporting the positive displacement pump; and

a remote control in communication with the console and positionable within the sterile field, wherein the remote control is separate from and independent of the respective surgical instrument,

wherein both the console and the remote control provide the electronic finger-touch selection of the flow rate via one of the respective first and second modes.

23. The surgical fluid manager of claim 22 wherein the user interface, including both the console and the remote control, comprises:

an adjustment mechanism configured to cause at least one of an increase or a decrease in the selected flow rate by a numeric value via discrete intervals of at least one order of magnitude less than the order of magnitude of the selected flow rate.

24. The surgical fluid manager of claim 19 wherein in the second mode, the flow rate is selectable via the alphanumeric size identifiers in correspondence with performing a surgical procedure using at least one of successively larger surgical instruments or successively smaller surgical instruments throughout the procedure in which each successive alphanumeric size identifier corresponds to the next instrument size for the procedure.

20. (canceled)

25. A surgical fluid manager comprising:

a positive displacement pump releasably engageable to tubing; and

a user interface configured to enable electronic finger-touch selection of a fluid flow rate through the tubing and through a first surgical instrument connectable to the tubing, wherein the user interface is configured to directly control the flow rate via user selection of one of a plurality of displayable, selectable digital numeric values, wherein the user interface includes;

a console positionable external to a sterile field and supporting the positive displacement pump;

a remote control in communication with the console and positionable within the sterile field, wherein the remote control is separate from and independent of the respective surgical instrument;

wherein both the console and the remote control provide the electronic finger-touch selection of the flow rate; and

a displayable, adjustment mechanism configured to cause at least one of an increase or a decrease in the selected flow rate, via the console or the remote control, by a numeric value via discrete intervals of at least one order of magnitude less than the order of magnitude of the selected flow rate.

26. A surgical fluid manager comprising:

a positive displacement pump releasably engageable to tubing; and

a user interface configured to enable electronic finger-touch selection of a fluid flow rate through the tubing and through a first surgical instrument connectable to the tubing, wherein the user interface is configured to directly control the flow rate via user selection of one alphanumeric size identifier within a scale of displayable, alphanumeric size identifiers wherein each respective alphanumeric size identifier directly corresponds to just one surgical instrument size within a scale of different surgical instrument sizes, wherein the different surgical instrument sizes relate to substantially the same type of surgical instrument, including the first surgical instrument.

27. The surgical fluid manager of claim 26 wherein the user interface is configured to enable selection of the flow rate via the alphanumeric size identifiers in correspondence with performing a surgical procedure using at least one of successively larger surgical instruments or successively smaller surgical instruments throughout the procedure in which each successive alphanumeric size identifier corresponds to the next instrument size for the procedure.

28. The surgical fluid manager of claim 26, comprising:

a displayable, adjustment mechanism configured to cause at least one of an increase or a decrease in the selected flow rate by a numeric value via discrete intervals of at least one order of magnitude less than the order of magnitude of the selected flow rate.

29. The surgical fluid manager of claim 28, wherein the user interface includes:

a console positionable external to a sterile field and supporting the positive displacement pump;

a remote control in communication with the console and positionable within the sterile field, wherein the remote control is separate from and independent of the respective surgical instrument; and

wherein both the console and the remote control provide the electronic finger-touch selection of the flow rate.

30. A surgical fluid manager comprising:

a positive displacement pump releasably engageable to tubing; and

a user interface configured to enable electronic finger-touch selection of a fluid flow rate through the tubing and through a first surgical instrument connectable to the tubing, the user interface configured to convertibly operate between;

a first mode configured to control the flow rate via user selection of one of a plurality of displayable, selectable digital numeric values;

or

a second mode configured to control the flow rate via user selection of one alphanumeric identifier within a scale of displayable, alphanumeric size identifiers wherein each respective alphanumeric size identifier directly corresponds to just one surgical instrument size within a scale of different surgical instrument sizes, wherein the different surgical instrument sizes relate to substantially the same type of surgical instrument, including the first surgical instrument, and

wherein the user interface includes;

a console positionable external to a sterile field and supporting the positive displacement pump;

a remote control in communication with the console and positionable within the sterile field, wherein the remote control is separate from and independent of the respective surgical instrument, wherein both the console and the remote control provide the electronic finger-touch selection of the flow rate via one of the respective first and second modes; and

an adjustment mechanism configured to cause at least one of an increase or a decrease in the selected flow rate by a numeric value via discrete intervals of at least one order of magnitude less than the order of magnitude of the selected flow rate.

31. The surgical fluid manager of claim 30 wherein the respective surgical instrument sizes are determined by a cross-sectional area of a respective one of the surgical instruments and wherein each respective surgical instrument includes an irrigation conduit through which the fluid flows.
