DETAILED DESCRIPTION

Referring to FIG. 1 , a control console 100 including fluid management capabilities in accordance with the present disclosure is configured to releasably receive one or more fluid management cassettes 210, 220, 230 within one or more cassette bays 170, 180 thereof. Control console 100 may include: a housing 110, an ON/OFF button 120; a graphical user interface 130, one or more power ports 140 for powering and controlling connected powered surgical instrument(s), one or more energy ports 150 for providing surgical energy, e.g., nonpolar, bipolar, microwave, ultrasonic, thermal, light, and/or other surgical energy, to connected energy-based surgical instrument(s), one or more additional ports 160; and a plurality of cassette bays 170, 180 of one or more different types. Control console 100 may further include one or more central processing units (CPU's) and/or microcontroller units (MCU's), power generating and control hardware, surgical energy generating and control hardware, motor control hardware, pump control hardware, and/or any other suitable hardware and corresponding firmware/software stored thereon for operating and controlling operation of surgical instrument(s), cassette(s), and/or other devices or components connected thereto.
With respect to the cassette bays 170, 180, one or more first cassette bays 170 may define a first shape to receive a first configuration of cassette 210 and one or more second cassette bays 180 may define a second, different shape configured to receive a second configuration of cassette 220, 230. Each cassette bay 170, 180 includes a motor 190 (FIG. 3 ) of control console 100 associated therewith. Each motor 190 (FIG. 3 ) includes a drive rotor 192 (FIG. 3 ) coupled thereto and configured to be driven rotationally by the corresponding motor 190 (FIG. 3 ). Each drive rotor 192 (FIG. 3 ), more specifically, is configured to extend into the corresponding cassette bay 170, 180 such that, when a cassette 210, 220 is engaged therein, the drive rotor 192 (FIG. 3 ) extends into the cassette 210, 220 to operably engage an internal operable assembly, e.g., a pump, therein. Fluid tubing connection ports 212, 222 on the face plates of cassettes 210, 220, respectively, enable inflow and outflow connections to cassettes 210, 220 (and, more specifically, to the pumps therein) such that rotational driving of the appropriate drive rotor 192 (FIG. 3 ) via the corresponding motor 190 (FIG. 3 ) activates the pump to urge fluid along a corresponding fluid flow path, e.g., 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.
With additional reference to FIGS. 2A, 2B, and 3 , although control console 100 is configured to drive cassettes 210, 220 having internal operable assemblies, e.g., pumps, therein, it is understood that for some surgical procedures, for use with some surgical devices, based on some clinician's preference, and/or for other reasons, it may be desirable to enable use of a peristaltic pump with control console 100. However, a peristaltic pump is not capable of being positioned within cassettes 210, 220 or cassette bay 170, 180. Accordingly, cassette 230 provided in accordance with the present disclosure functions as a peristaltic pump adapter cassette 230 for use with control console 100.
Cassette 230 includes a housing 232 configured for insertion into and releasable engagement within one of cassette bays 180 of control console 100. Cassette 230 further includes a peristaltic pump 300 mounted on a front end of housing 232 opposite the insertion end thereof. A drive shaft 234 extends through housing 232 of cassette 230 and is rotatably supported therein by insertion end and front end bearings 236, 238, respectively. Drive shaft 234 includes a front end 235 a that is operably engaged with peristaltic pump 300 such that rotation of drive shaft 234 drives peristaltic pump 300 and an insertion end 235 b configured to releasably operably receive a corresponding drive rotor 192 when cassette 230 is received within one of the cassette bays 180 of control console 100. In this manner, when cassette 230 is received within one of the cassette bays 180 of control console 100, rotational driving of drive rotor 192 by motor 190 drives rotation of drive shaft 234 to thereby drive peristaltic pump 300, thus enabling control console 100 to control operation of peristaltic pump 300.
In aspects, cassette 230 includes a Radio Frequency Identification (RFID) tag or other suitable wireless communication device 240 disposed on or within housing 232. In such aspects, cassette bay 180 may include an RFID antenna or other suitable wireless communication device 182 disposed thereon or therein and configured for alignment with RFID tag 240 of cassette 230 when cassette 230 is received within cassette bay 180. As such, control console 100 may be able to read information from and/or write information to cassette 230 when cassette 230 is received within cassette bay 180. Such information may include, without limitation, a type of the cassette 230, a serial number of cassette 230, manufacture information (e.g., lot, batch, manufacture date, manufacture location, etc.), calibration and/or setting information relating to peristaltic pump 300, use information (whether the cassette has been used, a number of uses, whether the cassette has been sterilized, etc.), and/or any other suitable information. Calibration and/or setting information relating to peristaltic pump 300 may be utilized, for example, to facilitate control and operation of peristaltic pump 300 by control console 100.
It will be understood that various modifications may be made to the aspects and features disclosed herein. Therefore, the above description should not be construed as limiting, but merely as exemplifications of various aspects and features. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended thereto.
