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.

The present invention relates to a pressure-stabilized ear flushing device capable of being operated with one hand, comprising a spray bottle, a spray gun, a long rod for solution transition, and an adapter and a flushing head provided on the long rod. The flushing bottle is provided with a suction tube. The suction tube is connected with the spray gun. The spray gun and the spray bottle are threaded or snapped. The spray head on the spray gun is connected with a long rod. The end of the long rod is connected with a triangular flushing nozzle or an adapter. The other end of the adapter is connected with a hose flushing head. The device of the present invention improves the existing ear flusher, flushes earwax better, treats ears, and is capable of being operated with one hand, which is convenient for users and patients. The device is equipped with a variety of flushing heads, which is suitable for a wide range of people and is convenient and fast to operate.

A fluid management system for use with a fluid reservoir includes an inflow pump and an outflow pump. The inflow pump is connectable to a probe for delivering a distention fluid to a body cavity. The outflow pump removes the distention fluid through the same probe, thus establishing a re-circulating volume of distention fluid within the body cavity. The removed fluid is filtered and returned to a fluid reservoir for eventual recycling to the body cavity. A controller adjusts the flow rates of the inflow pump and the outflow pump to maintain a pre-selected fluid pressure or volume within the body cavity.

A method and apparatus for injecting saline into an open cavity of a patient's body, and, alternatively, vacuuming fluids from said cavity during laparoscopic surgery that provides constant feed and amplified pressure to provide a steady fluid output, in a disposable, single use handheld surgical device.

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.

Described is a phacoemulsification device for eye surgery that generally comprises an ultrasonically vibrating aspiration needle that withdraws ocular material from inside of the eye. The ocular material withdrawn from the eye is equally replaced with irrigation fluid provided through irrigation ports in an irrigation sleeve surrounding the aspiration needle. In the event the aspiration needle stops withdrawing ocular material, such as if it becomes occluded with a chunk of ocular material, irrigation fluid is directed to the outside of the eye via at least one irrigation aperture to keep the eye cool where the needle is ultrasonically vibrating.

The invention relates to a device for rinsing a body cavity, wherein a pressure sensor for determining the actual pressure in the body cavity is provided, said pressure sensor being arranged in the drainage line (8).

An irrigation system for anal or stomal irrigation includes a reservoir, a tubing system providing a first flow path between the reservoir and a catheter, and a pressure channel separate from the first flow path. A pump is operable to move the liquid through the first flow path from the reservoir and through the catheter. A control system is connected to the tubing system. A connector couples the tubing system to the catheter, where the connector includes a chamber coupling the pressure channel to the first flow path, with a membrane located in the chamber between the first flow path and the pressure channel. A pressure sensor communicates with the control system which operates the pump to control the anal or the stomal irrigation with the liquid based on the pressure sensed in the first flow path.
