Excellent performance of smart needle demonstrated in clinical tests
A research paper about tissue-identifying smart needle in lumbar puncture has been published on August 4th, 2016 by Journal of Clinical Monitoring and Computing. The clinical research was conducted with adult patients in three hospitals in Tampere region, Finland.
The Term Smart Needle implies a smart component has been added on an established healthcare product – the needle. The intelligence of the studied smart needle is its capability to identify the tissue at the tip of the needle. Traditionally physician has to rely on haptic perception through the needle handle to estimate where the tip penetrates patient. In lumbar puncture extreme care has to be taken so that excess tissue damage in sensitive spine area does not occur.
The smart needle improves current practice by providing an alert when the tip of the needle becomes in contact with spinal fluid. The physician is then alerted that the needle has reached spinal canal and the tip is in close proximity to sensitive nerves of the spine.
Excellent performance is no surprise to developers. "Based on both literature and our previous research, we knew that Injeq IQ-Needle™ can identity various tissues in real-time. We are, nevertheless, positively surprised for such excellent results achieved in clinical use." comments Kai Kronström, CEO, Injeq.
Injeq continues clinical research of the IQ-Needle with new patient groups undergoing lumbar puncture to obtain diagnostic spinal fluid sample. The company is also running clinical trials with IQ-Biopsy system that integrates tissue identification to core biopsy needle. Mr Kronström concludes "We've seen smart phones to take over the mobile phone business. There's no doubt eventually the Smart Needle will replace traditional needle and Injeq is in good position to drive this transformation."
