Ultrasound guidance system for needle tip tracking

Onvision is an Ultrasound based Needle TipTracking Technology for Peripheral Nerve Blocks that works exclusively with Xperius Ultrasound System and the dedicated Stimuplex Onvision needle.
In real-time, Onvision accurately indicates where the needle tip is inside the body, in or out of plane. It helps users to align the needle with the probe in an intuitive and easy to use manner - for improved pain relief and the avoidance of unintended nerve puncture or collateral damage to surrounding tissue or vessel.

Ultrasound based Technology for reliable needle guidance

The dedicated Stimuplex Onvision Needle with embedded tip sensor allows the exact detection of the tip location and display this information in real time on the live Xperius Ultrasound image.  Needle tip tracking can be used for 2D Mode with the Nerve 0‑4 cm and the Nerve 4‑6 cm preset on the L12-4 transducer and Nerve 6+ cm presets on the C5-2 transducer.

Technical working priciple

The Onvision system detects the exact location of the Stimuplex Onvision tip sensor using the three dimensional space of the Ultrasound beam. The technology combines ultrasound image data from the ultrasound system with signals from the needle to accurately locate the position of the sensor on the Onvision Needle. This projects the position of the sensor by overlaying a circle over it on the ultrasound image in real time.

 

Ultrasound based technology to improve accuracy

• Onvision works up to 12 cm
• Onvision is shielded against electromagnetic interferences (EMI)
• Onvision is accurate even when the needle bends

Needle guidance to the point

Onvision is a straightforward-to-adopt ultrasound guidance system that is easy to learn and use. The needle tip position is indicated by circles that are displayed on the ultrasound image. The circles appear automatically when the needle tip sensor enters the imaging plane.

Onvision helps to seeing the needle tip and to master the needle beam alignment in an intuitive and easy to use manner. With Onvision, users experience a real time guidance which empowers them to quickly adopt and integrate PNB into their daily practice – enables more physicians to be proficient in performing PNBs.
