"Intra-needle ultrasound - anesthesia probe provides an innovative way to puncture preciselysafely in thoracic regional anesthesia, especially for high BMI patients. In clinical practice, the anesthetic techniques are performed under ultrasound-guidance. The unmet medical need is to resolve the difficulty in needle tip imaging for high BMI patients. This technique provides an innovative way for pleura identification, tracking, distance measuring,early warning in real-time. It greatly reduces the risk of pleural puncturepneumothorax,improves the safety."
