A fluid handling system includes a console configured to connect with a first electrical interface that is configured to connect to a plurality of components of the fluid handling system, the console including a second electrical interface configured to connect with the first electrical interface, a display, and one or more hardware processors. A control system includes the one or more hardware processors and a non-transitory memory storing instructions that, when executed, cause the control system to: detect an electrical signal from a first component of the plurality of components of the fluid handling system responsive to a caretaker performing a first instruction; determine a system state of the fluid handling system based at least in part on the electrical signal from the first component; compare the system state with a predetermined state condition corresponding to said first instruction; and output an indication on the display of the system state.

Various embodiments of a fluid handling system are disclosed herein. For example, the fluid handling system can include a catheter assembly and a console configured to control the operation of the catheter assembly. A removable interface member can be configured to provide fluid and electrical communication between the catheter assembly and the console. Additionally, a control system is disclosed for controlling operation of the fluid handling system.

A system for managing fluid levels in phacoemulsification surgery is disclosed. The system comprises a surgical console having at least one system bus communicatively connected to at least one computing processor capable of accessing at least one computing memory associated with the at least one computing processor, and at least one sensor associated with the surgical console for providing at least one signal indicative of the presence of liquid, wherein the at least one sensor is in communication with at least one level sensing device of a cassette associated with the surgical console.

A system for a surgical system is disclosed, comprising system for distributing fluid in a surgical cassette, comprising at least one at least partially deformable bladder at least partially disposed on at least one rigid surface, wherein the bladder forms a portion of a channel, at least a first and second port in fluid communication with the channel, wherein the channel comprises at least two portions having a substantially uniform first dimension separated by a second portion have a second dimension, and wherein at least two pump head rollers are engaged with the bladder.

A system for distributing fluid during a surgical procedure is disclosed, comprising a plurality of valves at least partially enclosed in a surgical cassette, at least one vacuum source fluidly connected to at least one of the plurality of valves, and at least one fluid source fluidly connected to at least one of the plurality of valves, wherein each valve is responsive to at least one received signal indicative of at least one parameter associated with one of fluid pressure and fluid volume.

A system for a surgical system is disclosed, comprising a surgical cassette, comprising a cassette for use with a surgical console, further comprising a first set of fluid channels having a first set of ports, a second set of fluid channels having a second set of ports, at least one rotary valve in fluid communication with the first set of fluid channels, at least one rotary valve in fluid communication with the second set of fluid channels, and a plurality of deformable channels, wherein the deformable channels are fluidly connected to ones of the first set of ports and second set of ports.

A system for a surgical system is disclosed, comprising a system for distributing fluid in a surgical cassette, comprising a first pump head operable by a first drive shaft and a second pump head operable by a second drive shaft, wherein the second drive shaft is at least partially enclosed by the first drive shaft.

A pressure and vacuum pump including at least two diaphragm pump heads for providing vacuum and pressure simultaneously. The dual function pump reduces number of required pumps, is traditionally quieter, and enables the system to run at a lower duty cycle. A drive in the pump housing causes a connecting rod to oscillate a diaphragm to move up and down thereby causing air to be either drawn into an inlet or forced out via an exhaust.

A cassette for collecting a tissue sample. The cassette includes a housing configured to be removably coupled with a manifold receiver of a medical fluid collection system. The housing defines a first void space, a second void space, and an outlet opening. A catch tray is removably positionable within the first void space and includes a screen defining porous features for collecting the tissue sample. A filter element separate from the catch tray is disposed within the second void space. The housing may include a cap portion defining the first void space, and a shell portion coupled to the cap portion and defining the second void space. The cassette may be simultaneously operable in a tissue collection mode in which fluid is suctioned across the catch tray to collect the tissue sample, and a bypass mode in which the fluid is not suctioned across the catch tray.

A surgical cassette for use with a phacoemulsification system having a front plate, a back plate, and a gasket therebetween. The front plate having molded fluid channels that mate with the gasket. The gasket having multiple valves and a sensor or diaphragm accessible through the back plate.
