Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
109 words
An ultrasonic surgical instrument adapted to be mounted within an endoscope for inserting within an internal body organ, comprising an elongated probe, a transducer for inducing oscillation therein, means for connecting said transducer to one end of said probe, and a unitary jacket surrounding said probe and said transducer, said jacket being in cross section larger than said probe and transducer and having a pair of axially spaced radially inwardly directed bearing means for supporting said jacket on said transducer and on the probe at the end opposite said transducer spaced uniformly from said probe and said transducer to provide a radial air gap enveloping said probe and transducer.
