Abstract
Abstract A holder for a needle guide sleeve for use in cooperation with an ultrasonic probe. The holder comprises a base portion configured to engage the probe and an upwardly extending arm provided with a slot with which the needle guide sleeve rests. The needle guide sleeve within the slot is movable only in the two dimensions of the picture generated by the ultrasound probe, and can be inserted with or removed from the holder even when the transducer is in place with the human body.
