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.
Claims11
A biopsy attachment for a probe having a transducer for producing a beam of ultrasonic energy, said attachment comprising:
- (a) a housing associated with the probe and having a recess;
- (b) a bushing having an axial aperture of given length for receiving a biopsy needle and surrounding, engaging and supporting said needle throughout said length;
- and
- (c) said bushing and said housing having cooperable means responsive to positioning the bushing in a first angular position relative to the housing for effecting displacement of the bushing into the recess to an inserted position, and responsive to the rotation of the bushing in one direction, when in its inserted position, from its first angular position, for frictionally holding the bushing in a second angular position.
