摘要

An ultrasonic probe assembly (24) is provided. The probe assembly (24) includes a cannula (40), and an ultrasonic probe (22) disposed within the cannula (40). The probe assembly (24) further includes a low friction bushin g (28) disposed within the cannula (40), adapted to maintain the cannula (40), and ultrasonic probe (22) in a relatively fixed longitudinal relationship.
