<P>PROBLEM TO BE SOLVED: To provide a surgical system having an ultrasonic flow sensor with a small error of flow measurement. <P>SOLUTION: A surgical system having a console that receives a cassette with a rigid fluid channel formed into a rigid plastic component or housing. The housing serves as a substrate for an elastomeric acoustic coupling that can be formed on the housing outside the fluid channel. The acoustic transducer is elastically mounted within the console, such as on a spring, so as to provide a relatively constant force between the transducer and the acoustic coupling when the cassette is installed in the console. <P>COPYRIGHT: (C)2008,JPO&INPIT |
