The P4-1 and E9-4 needle guides are designed to work in conjunction with biopsy software on Zonare’s z.one ultrasound platform, providing physicians with increased productivity during ultrasound-guided procedures including tissue biopsy, fluid aspirations and catheter placement. CIVCO’s needle guidance systems offer physicians reduced technique variability, providing a shorter learning curve and reduced procedure time. The reusable E9-4 endocavity guide consists of only one part, allowing for ease-of-use, as well as a secure and stable fit to the transducer. The needle guide attaches to the probe by locking onto locator grooves on the transducer, ensuring proper positioning and safety throughout the procedure. The E9-4 guide also features zero needle resistance offering smooth movement and navigation during puncture procedures. This endocavity guide accepts instruments from 16-18 gauges sizes.
