Abstract
A needle guide having a semi-compliant shell design and locating means for attachment to an ultrasound transducer. The needle guide improves over the prior art in its reduced complexity, its low-profile formed fit to the transducer, a positive guide locking feature when the needle holding pin is in the closed position, and its ease of attachment over a sterile cover. The improved design is conducive to low-cost manufacturing methods which employ materials that can be autoclaved, gas-sterilized, or liquid disinfected.
