Embodiments describe a light-based medical device that uses light to luminesce tissue, and collect the reflected light, to perform analysis on the reflection characteristics in real-time to detect the type of surrounding tissue as well deeper tissue in the trajectory of the luminescence. Such device can be incorporated inside needles, catheters, tubes or piercing or biopsy tools, surgical blades, surgical tweezers, and so on, to direct their insertions and operations in specific zones. Importantly, because of the easy-to-use design, embodiments can be used without the need of highly trained personnel or expensive hospital equipment. Therefore, embodiments can be utilized in emergency situations that require fast responses, performed in ERs, moving vehicles, ambulances, and battlefields. |
