ABSTRACT:
'A biopsy attachment for a probe having a transducer for producing a beam of ultrasonic energy includes a housing associated with the probe and a bushing having an axial aperture for receiving a biopsy needle. The housing has an aperture for attaching the bushing to the housing. The bushing and the housing are constructed and arranged so that by positioning the bushing in a first angular position relative to the housing, a lateral displacement of the bushing into the recess can take place until the bushing reaches an inserted position. Thereafter, rotation of the bushing in one direction from its first angular position to a second angular position causes the bushing to frictionally engage the housing retaining the bushing to the housing.
