ABSTRACT:
An irrigation system and method for providing fluid from a source of irrigating fluid to a surgical site, in particular a surgical site access to which is provided by a small incision or a natural orifice of the body. The irrigation system includes a control unit that is used with a cassette. The control unit includes a motor under the control of a controller, a sensor for sensing the flow of fluid in the cassette, a sensor for sensing pressure in the cassette, and a user control panel. The cassette includes a fluid flow passageway having an inlet connected to the source of irrigating fluid and an outlet for providing fluid to the surgical site. A pump located in the cassette is driven by the motor. The pump has limited efficiency when presented with back pressure to thereby limit to a safe level an amount of pressure that can be delivered to the surgical site. The system may be used to irrigate or distend a surgical site.
