Royal Philips and B. Braun have introduced Onvision needle tip tracking to facilitate real-time ultrasound guidance in regional anaesthesia procedures.
Onvision allows accurate placement of the needle tip in the body. It will be available on the new variant of the B. Braun and Philips Xperius ultrasound system.
Precise needle positioning is significant in terms of effective pain relief, as well as avoiding nerve and vessel punctures or damage to surrounding tissue in regional anaesthesia procedures.
Real-time ultrasound imaging has been in use for needle guidance. However, it does not offer optimal visualisation of the needle tip, according to the companies.
Onvision simplifies the alignment between the needle and the ultrasound probe, enabling a better interpretation of the ultrasound image.
The launch is part of the companies’ partnership, which focuses on ultrasound-guided regional anaesthesia.
Royal Philips image-guided therapy chief business leader Bert van Meurs said: “By combining B. Braun’s expertise in needle design with Philips’ capabilities in real-time image guidance, we’ve created a solution to one of the biggest challenges in regional anaesthesia – accurate positioning of the needle tip in the body.”
The combination of Stimuplex Onvision needles by B. Braun with Philips’ Onvision needle tip tracking technology provides an accuracy of better than 3mm in specifying the needle tip’s position relative to the 2D ultrasound viewing plane.
This real-time location of the needle tip is due to a micro-sensor placed on the needle, along with the Xperius system’s signal processing and visualisation capabilities.
Philips and B. Braun added that the ultrasound guidance solution also offers improved flexibility in needle trajectory and can cut procedure times.
Xperius and Onvision are co-branded and available through B. Braun’s global sales network, while Philips is responsible for installation and service.
