Abstract
Several embodiments of medical ultrasound handpieces are described each including a medical ultrasound transducer assembly. An embodiment of a medical ultrasound system is described, wherein the medical ultrasound system includes a medical ultrasound handpiece having a medical ultrasound transducer assembly and includes an ultrasonically-vibratable medical-treatment instrument which is attachable to a distal end of the transducer assembly. An embodiment of a medical ultrasound system is described, wherein the medical ultrasound system has a handpiece including a medical ultrasound transducer assembly and including a housing or housing component surrounding the transducer assembly. A method for tuning a medical ultrasound handpiece includes machining at least a distal non-threaded portion of an instrument-attachment stud of the transducer assembly to match a measured fundamental frequency to a desired fundamental frequency to within a predetermined limit. A method for making a medical ultrasound transducer assembly determines acceptable gains for gain stages of the transducer assembly.

34. A medical ultrasound system comprising:
-
a) a medical ultrasound transducer assembly which has a distal end portion; and
b) an ultrasonically-vibratable medical-treatment instrument which is attachable to the distal end portion of the transducer assembly, wherein the transducer assembly and the attached instrument together have an operating wavelength, wherein the transducer assembly alone has a length which is at least equal to ¼
of the operating wavelength and which is less than ½
of the operating wavelength, and wherein the transducer assembly and the attached instrument together have a length equal to N times ½
of the operating wavelength, wherein N is a non-zero positive whole number. - View Dependent Claims (35, 36, 37, 68, 69, 70, 71)
