Clearer, Brighter: Ultrasound and the CCR Revolution


Havel’s “4×4 CCR Pattern” provides maximum reflection for echogenic needles under ultrasound.

A change in methodology created the need for an ultrasound-guided needle

Part Two: Corners, Cubes and the Havel’s Advantage 

Earlier, we looked at how ultrasound-guided needle injections are beginning to dominate the field of regional anesthesia. Terms like “echogenicity” and “needle visualization” became important talking points for doctors wanting a better needle. If the biggest problem was visibility, the answer was found in just three simple letters: CCR.

CCR stands for “corner cube reflectors,” and these multi-angled surfaces reflect sound waves back to the transducer, making the needle appear brighter and clearer on screen. These surfaces offer a number of advantages, including improved shaft and needle tip visibility, thus making the needle more echogenic. CCR marks ensure more exact needle placement in ultrasound-guided procedures like peripheral nerve blocks and muscular skeletal injections, and allow you to see the needle and anesthetic in real-time.

In today’s market, CCR-type markings on both the shaft and near the tip of the needle are common, and this placement does help with echogenicity. However, it makes identifying the exact position of the needle tip more difficult, as one might become confused at differentiating between the shaft and the tip. Ultimately, this defeats the purpose of using an echogenic needle, and it’s why Havel’s has developed special echogenic needles that eliminate the confusion.


Benefits of ultrasound guidance include better accuracy, faster needle placement and real-time monitoring of anesthesia flow.

At Havel’s, we’ve created what’s called our “4×4 CCR Pattern,” which helps pinpoint the exact location of the needle tip once inside the body. Our echogenic needles have four rows of four multi-angled indentations at the distal end of the needle, which circle around the entire cannula, making the tip appear brighter and in full-view. A total of 16 corner cube reflectors are placed within the first 5.5mm of the needle, allowing you to focus on the tip without any other distractions.

Other competitors have reflectors as far up as 20mm of the cannula, which drives up cost and could potentially lead to a false assumption of the needle tip’s actual location. An abundance of reflectors could also blur the target area and create a cloud around the needle. In the end, you shouldn’t pay more for what you don’t need, and with our line of echogenic needles, you get exactly what you need at an affordable price.

Havel’s EchoStim and EchoBlock needles include four rows of four corner cube reflectors placed within the first 5.5mm of the needle, which helps to easily identify the location of the needle tip.

Havel’s 4×4 CCR Pattern is available on some of our most popular insulated and non-insulated needles, including the EchoStim, EchoBlock and EchoBlock MSK. Advantages to our 4×4 pattern include better accuracy, faster needle placement, increased success rates and reduced needle sticks and breaks. The 4×4 CCR Pattern also lessens the need for needle rotation because the CCR marks appear around the entire tip. Our echogenic needles allow you to see the needle, confirm the trajectory, locate the tip and watch the anesthetic encircle the target area. At Havel’s, our focus is on the tip, and yours should be too.
