Abstract
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.
Claims27
A light-based medical device, comprising:
- a needle comprising a distal tip configured for tissue penetration;
- a light source and a light detector positioned proximate to the distal tip of the needle, wherein the light source is operable to emit light toward tissue and the light detector is operable to detect light reflected from the tissue;
- and
- a light-blocking structure positioned to optically isolate the light detector from direct emission of the light source while permitting detection of the reflected light from the tissue.
A light-based medical device, comprising:
- a needle comprising a distal tip configured for tissue penetration;
- a light source and a light detector;
- and
- a controller module coupled with the light source and the light detector and comprising functionality to:
- receive light measurement data from the light detector;
- analyze the light measurement data in real-time to determine tissue characteristics;
- and
- generate feedback signals regarding the determined tissue characteristics.
A light-based medical device, comprising:
- a reusable optical module comprising a light source, a light detector, and a controller module;
- a removable tool component configured for tissue penetration and comprising a coupling interface configured for removable attachment to the reusable optical module;
- and
- an optical transmission system extending between the reusable optical module and the removable tool component, wherein the optical transmission system is configured to direct light from the light source through the removable tool component toward tissue and return reflected light from the tissue to the light detector.
