Abstract

A shoulder is connected to a transducer housing in substantial alignment with the plane of an ultrasound beam provided at one end of the housing. An ascending link is pivotally connected to the shoulder, a descending link is pivotally connected to the ascending link and a needle mount is pivotally connected to the descending link. The ascending link, descending link and needle mount are movable in substantial alignment with the plane of the ultrasound beam. The needle guide may be generally cylindrical and a disposable needle-receiving sleeve may be inserted into a guideway formed in the needle mount. Alternatively, the needle mount may be a disposable cube-like structure readily attachable to and detachable from the descending link. In the latter form, the needle mount is provided with a guideway slot defined by relatively spaced apart end walls of the mount which are generally equal in height to the width of the guideway defined by the space therebetween. In this manner, approximately a 45 degree angle may be obtained by a biopsy needle inserted into the guideway.
