Patent Images
1. A method of performing surgery comprising:
- locating both a first surgical instrument and a remote control of a fluid manager within a sterile field while locating a peristaltic pump external to the sterile field;
selecting as an independent variable, via the remote control, a first fluid flow rate as a digital numeric value; and
performing a surgical procedure using the first surgical instrument, including directing the irrigation fluid through tubing, via the peristaltic pump at the first fluid flow rate, and through the irrigation conduit of the first surgical instrument onto the treatment site.

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.

7. A method comprising:
-
locating both a first surgical instrument and a remote control of a fluid manager within a sterile field while locating a pump external to the sterile field; selecting as an independent variable, via the remote control, a first fluid flow rate as a digital numeric value; performing a surgical procedure using the first surgical instrument, including directing an irrigation fluid through tubing, via the pump at the first fluid flow rate, and through an irrigation conduit of the first surgical instrument onto the treatment site; providing a plurality of selectable surgical instruments which range in cross-sectional size according to a scale defined by a discrete interval between successive sizes within the range of cross-sectional sizes, wherein the plurality of instruments include at least the first surgical instrument and a differently sized, second surgical instrument; providing a plurality of selectable fluid flow rates, including at least the first fluid flow rate and a second fluid flow rate, represented by a plurality of alphanumeric identifiers wherein each respective fluid flow rate is calibrated to directly correspond to the cross-sectional size of one of the respective selectable surgical instruments; and selecting one of the respective fluid flow rates, via the remote control within the sterile field, by selecting one of the alphanumeric identifiers corresponding to the cross-sectional size of the second surgical instrument. - View Dependent Claims (8)

9. A method comprising:
-
locating both a first surgical instrument and a remote control of a fluid manager within a sterile field while locating a pump external to the sterile field; selecting as an independent variable, via the remote control, a first flow rate as a digital numeric value; and performing a surgical procedure using the first surgical instrument, including directing the irrigation fluid through tubing, via the pump at the first fluid flow rate, and through the irrigation conduit of the first surgical instrument onto the treatment site; and implementing the selected first fluid flow rate as an average flow rate via a series of pulses in which each individual pulse directs the irrigation fluid at a second fluid flow rate substantially greater than the average flow rate and wherein the respective pulses are separated from each other by no-flow intervals in which no fluid exits the irrigation conduit onto the treatment site. - View Dependent Claims (10)

11. A method comprising:
-
locating both a first surgical instrument and a remote control of a fluid manager within a sterile field while locating a pump external to the sterile field; selecting as an independent variable, via the remote control, a first fluid flow rate as a digital numeric value; performing a surgical procedure using the first surgical instrument, including directing the irrigation fluid through the tubing, via the pump at the first fluid flow rate, and through the irrigation conduit of the first surgical instrument onto the treatment site; and arranging the fluid manager to enable electronic finger-touch selection of a fluid flow rate through the tubing and through the first surgical instrument, including configuring an user interface configured to operate convertibly between a first mode in which the selectable fluid flow rate, including the first fluid flow rate, is controllable via user selection of one of a plurality of selectable digital numeric values and a second mode in which the flow rate is controllable via user selection of one alphanumeric identifier within a scale of alphanumeric identifiers wherein each respective alphanumeric identifier directly corresponds to just one instrument size within a scale of instrument sizes. - View Dependent Claims (12)
