CIVCO Medical Solutions now offers a reusable endocavity needle guide for use with the Philips C9-4ec transducer on the HD3 ultrasound system; and for use with Medison's EC4-9/10ED and EC4-9/13CD transducers on the SONOACE 9900 and ACCUVIX XQ ultrasound systems. This reusable biopsy guide is engineered to direct minimally invasive instruments by following on-screen guidelines, providing the imaging professional a fixed path of guidance and a standard of precision in biopsy procedures. The use of a needle guide aids in procedural efficiencies and patient comfort, leading to better patient care. The guide is secured to the transducer by repositioning and tightening the thumbscrew into the closed position. The endocavity guide accepts instruments from 16-18 gauge sizes.
