Abstract
A heat-sterilizable ultrasonic surgical scanner includes an ultrasonic transducer and a permanent magnet motor for moving the transducer along an arcuate path. The scanner further includes a housing for the ultrasonic transducer and the motor. The housing includes an acoustically transparent window for transmitting ultrasonic energy from and into the housing. A resilient diaphragm permits expension and contraction of a coupling fluid with which the housing is filled without causing fluid loss from the housing due to leakage. The resilient diaphragm is mounted at a location remote from the acoustically transparent window.
