The present disclosure relates to surgical fluid management and, more specifically, to surgical devices and systems facilitating 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 appliances include micro-debriders, surgical drills, suction-irrigator instruments, tissue shavers, endoscopes, balloon or other catheters, energy-based devices, and the like.
A fluid management system may include capital equipment, e.g., a fluid management console, and disposable equipment, e.g., one or more cassettes, connectable to the fluid management console.
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 cassette configured for use with a control console. The fluid management cassette includes a housing configured for insertion into a cassette bay of a control console lead by an insertion end of the housing, a peristaltic pump mounted on a front end of the housing opposite the insertion end thereof, and a drive shaft extending through the housing and rotatable relative thereto. The drive shaft is operably coupled to the peristaltic pump at a front end of the drive shaft and includes an insertion end configured to operably engage a drive rotor of the control console upon insertion of the housing into the cassette bay of the control console.
In an aspect of the present disclosure, the drive shaft is supported within the housing by at least one bearing. In aspects, the drive shaft is supported within the housing via first and second spaced-apart bearings.
In another aspect of the present disclosure, a wireless communication tag such as, for example, a Radio Frequency Identification (RFID) tag, is disposed on or within the housing.
A fluid management system provided in accordance with aspects of the present disclosure includes a control console and a cassette. The control console includes a cassette bay, a motor, and a drive rotor operably coupled to the motor and extending at least partially into the cassette bay. The cassette includes a housing configured for insertion into the cassette bay of the control console lead by an insertion end of the housing, a peristaltic pump mounted on a front end of the housing opposite the insertion end thereof and configured to remain external of the control console, and a drive shaft extending through the housing and rotatable relative thereto. The drive shaft is operably coupled to the peristaltic pump at a front end of the drive shaft and includes an insertion end configured to operably engage the drive rotor of the control console upon insertion of the housing into the cassette bay of the control console.
In aspects of the present disclosure, the cassette may be configured similar to and include any of the features detailed above or otherwise herein.
In an aspect of the present disclosure, the control console includes a wireless communication device, e.g., an RFID antenna, disposed on or within the cassette bay and positioned to align with the wireless communication device, e.g., RFID tag, of the cassette upon insertion of the cassette into the cassette bay.
In another aspect of the present disclosure, the control console further includes at least one of a power port or an energy port.
Various aspects and features of the present disclosure are described hereinbelow with reference to the drawings wherein:
Referring to
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 (
With additional reference to
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 235a that is operably engaged with peristaltic pump 300 such that rotation of drive shaft 234 drives peristaltic pump 300 and an insertion end 235b 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.
