Reusable needle guidance system incorporates a multi-angle approach for improved anatomical access. Simple adjustment of the angle thumbscrew allows selection of the desired angle of access and securely locks the guide into position, providing a direct visual path for instruments to follow according to on-screen guidelines. A large quick-release tab allows easy detachment of the device from the transducer providing physicians increased flexibility during procedures. A unique v-slot insertion point accepts a full range of gauge sizes including: 8.5 French-23 gauge. Needle guides are shipped non-sterile. Select kits include sterile transducer covers and/or cleaning brushes, however sterile transducer cover kits, cleaning brushes, replacement thumbscrews and angle thumbscrews may be sold separately. Needle guides should be cleaned, disinfected and sterilized according to your User's Guide. NOTE: Reusable needle guides are recommended to follow FDA Guidelines for Reprocessing Ultrasound Transducer Assemblies including use of sterile barrier sheath, cleaning brush and proper cleaning and sterilization of the device between patients. Accurate needle path with on-screen guidelines offer physicians real-time visualization ensuring patient safety throughout the procedure. Repeatable, easy-to-use "quick-release" feature for detachment of guide provides physician flexibility during puncture procedures. Reduces technique variability providing a shorter learning curve and reduced procedure time.
