Sharpening Precision: How Wisonic’s WiNeedle Transforms Ultrasound‑Guided Injections

Meet Wisonic – Innovation at the Core

Founded in Shenzhen and now serving clinicians in 100+ countries with over 1,000 hospitals worldwide relying on its scanners, Wisonic Medical Technology has built its reputation on high‑performance, user‑centric ultrasound platforms that span everything from obstetrics to critical care.

The Needle‑Guidance Challenge

Whether you are delivering a peripheral nerve block, aspirating a cyst, or placing a central line, the hardest part is often seeing the needle. Metal shafts reflect sound poorly when they are not perfectly perpendicular to the ultrasound beam, forcing clinicians to spend extra time fanning the probe or making multiple passes—each of which adds patient discomfort and risk.

Enter WiNeedle – Intelligent Needle Enhancement

WiNeedle is Wisonic’s proprietary software that automatically detects the needle, steers the beam, and highlights both shaft and tip in real‑time. By recognizing metal artifacts and then dynamically adjusting beam angles, it paints the needle in bright echogenic color without sacrificing background tissue detail.

Key Capabilities

• Automatic needle detection – no need to manually toggle needle‑visualization modes.

• Smart beam steering – the system angles ultrasound lines toward the needle to maximize reflection.

• Tip & shaft tracking – both are independently labeled so you always know exactly where the bevel is.

• Hands‑free activation – WiNeedle engages as soon as the system senses a needle pattern, letting you keep one hand on the probe and the other on the syringe.

How It Works in the Procedure Room

Step	Action	What WiNeedle Does
1	Select an anesthesia, MSK, or vascular preset	Loads optimal frequency, depth & WiNeedle on‑board
2	Advance the needle under ultrasound	Detects metal reflection and overlays a colorized line showing shaft trajectory
3	Adjust probe or needle angle	Beam steering kicks in, keeping the tip bright even at steep angles
4	Deliver drug / sample	Real‑time feedback reduces the likelihood of overshoot, intraneural or intravascular placement

Clinical Impact

• Higher first‑pass success – studies using beam‑steering guidance consistently report fewer needle redirections.

• Shorter block times – less time spent finding the tip translates to faster turnover, a big win in ambulatory surgery centers.

• Improved safety – precise tip visualization minimizes complications such as nerve injury or arterial puncture.

• Easier training curve – residents can “see what right looks like,” shortening the number of supervised cases needed to gain competence.

“WiNeedle makes the needle pop right out—my residents stop hunting and can focus on the anatomy.” – Dr. L., Regional Anesthesiologist, California

Beyond Anesthesia

Because it is modality‑agnostic, WiNeedle has found a home in:

• Pain‑management injections (facet, epidural, SI joint)

• Biopsies & aspirations (thyroid, breast, soft tissue)

• Vascular access (PICC, central venous catheter, difficult IV)

• Regenerative medicine (PRP, stem‑cell)

Final Thoughts

Ultrasound‑guided interventions are only as good as the clinician’s ability to track a slender needle in a grayscale world. By fusing beam‑steering physics with smart pattern recognition, WiNeedle elevates Wisonic scanners from image generators to true interventional partners. The payoff is a smoother workflow, happier patients—and sharper accuracy where it matters most.
