The present disclosure relates to surgical fluid management and, more specifically, to surgical devices, systems, and methods facilitating multiple flow path fluid management.
Various surgical devices and systems utilize fluid management to facilitate performing a surgical task such as, for example, to irrigate a treatment site, aspirate a treatment site, clean a surgical device, wash a treatment site, clear a field of view, cool a surgical device, etc. Some non-limiting examples of these types of surgical devices include micro-debriders, surgical drills, suction-irrigators, tissue shavers, endoscopes, balloon or other catheters, energy-based devices, and the like.
Some surgical devices require fluid management of multiple fluid flow paths, for example, to enable two or more of irrigation, aspiration, cleaning, lavage, clearing, cooling, etc. As the number of fluid flow paths increases, additional tubing and/or valve structures are required to enable selective and independent management of each fluid flow path. This challenge is complicated by the desire to avoid contamination of capital equipment with fluid, e.g., avoiding fluid contact with the fluid management console and, instead, confining fluid travel to within the disposable, e.g., the cassette connectable to the fluid management console.
The terms “about,” substantially,” and the like, as utilized herein, are meant to account for manufacturing, material, environmental, use, and/or measurement tolerances and variations, and in any event may encompass differences of up to 10%. Further, to the extent consistent, any of the aspects described herein may be used in conjunction with any or all of the other aspects described herein.
Provided in accordance with aspects of the present disclosure is a fluid management system including a control console and a cassette. The control console includes a housing, a cassette bay defined within the housing, and an actuation mechanism disposed within the housing. The actuation mechanism includes a plurality of actuators. The cassette is insertable into the cassette bay of the control console and includes a chassis supporting a plurality of fluid flow paths through the cassette, and an outer housing defining at least one access opening providing access to the plurality of fluid flow paths. With the cassette positioned within the cassette bay, each actuator of the plurality of actuators is aligned with an access opening of the at least one access opening to enable each actuator, upon actuation thereof, to close a corresponding fluid flow path of the plurality of fluid flow paths.

In yet another aspect of the present disclosure, the first, second, and third sections are positioned adjacent the first, second, and third actuators, respectively. In such aspects, for each orientation of the cam roller, the presence of a protrusion in one of the first, second, or third section actuates the respective first, second, or third actuator, and wherein no protrusion in one of the first, second, or third section does not actuate the respective first, second, or third actuator.

With reference to
Upon receipt of fluid management cassette 200 within cassette bay 170, each side opening 222, 224, 226 of outer housing 220 of fluid management cassette 200 is aligned with one of the actuators 610 of actuation mechanism 600. In this manner, each actuator 610 of actuation mechanism 600 is aligned with tubing 243b, 245, 247 of one of fluid flow paths 242, 244, 246 of fluid management cassette 200, respectively. Thus, drivers 620 can be controlled to selectively deploy or retract the corresponding actuators 610 to thereby selectively leave open, fully close, or partially close the internal lumens defined through tubing 243b, 245, 247 and, thus, selectively control irrigation, lavage, and/or suction through surgical instrument 300 (

Fluid management cassette 1200 includes top openings 1222, 1224, 1226 defined within outer housing 1220 thereof. Further, the tubing 1243, 1245, 1247 associated with the first, second, and third fluid flow paths 1242, 1244, 1246 through fluid management cassette 1200, respectively, are routed to be exposed within top openings 1222, 1224, 1226, respectively. Other positions of top openings 1222, 1224, 1226 (e.g., on the sides, back, and/or other locations of cassette 1200) and/or routing configurations of tubing 1243, 1245, 1247 are also contemplated.
Actuation mechanism 1600 includes a frame 1610 formed with or attached to cassette bay 1170. Frame 1610 rotatably supports a rotor 1620 connected to a rotary motor 1630, e.g., a stepper motor or other suitable motor, configured to selectively drive rotation of rotor 1620 to a desired rotational orientation. A cam roller 1640 is disposed about rotor 1620 within frame 1610 such that rotation of rotor 1620 similarly rotates cam roller 1640. Frame 1610 further includes a plurality, e.g., three, spring-loaded actuators 1650, e.g., plungers, supported therein adjacent cassette bay 1170. Each spring-loaded actuator 1650 is biased towards a retracted or un-actuated position wherein the actuator 1650 does not extend into cassette bay 1170 and is movable from the retracted position to an extended position wherein the actuator 1650 protrudes at least partially into cassette bay 1170. Cam roller 1640 is configured and positioned to selectively urge none, one, some, or all of actuators 1650 from the retracted position(s) thereof to the extended position(s) thereof depending upon the orientation of cam roller 1640, as detailed below.
Upon receipt of fluid management cassette 1200 within cassette bay 1170, each top opening 1222, 1224, 1226 of outer housing 1220 of fluid management cassette 1200 is aligned with one of the actuators 1650 of actuation mechanism 1600. In this manner, each actuator 1650 of actuation mechanism 1600 is aligned with tubing 1243, 1245, 1247 of one of fluid flow paths 1242, 1244, 1246 of fluid management cassette 1200. Thus, cam roller 1640 can be driven to rotate to a desired rotational orientation to selectively deploy or allow spring-biased retraction of the corresponding actuator 1650 to thereby selectively leave open or close the internal lumens defined through tubing 1243, 1245, 1247 and, thus, to selectively control irrigation, lavage, and/or suction through surgical instrument 300 (
