Abstract

An intra-operative sensor device for detecting tissue or body parameters includes one or more light emitting sources and one or more photo-detectors. An optical isolator ring may be placed around either the one or more light emitting sources or around the one or more photo-detectors. The intra-operative sensor device may be a stand alone device or may be operatively coupled into a surgical instrument, such as a laparoscopic device.

Claims

1. An intra-operative sensor device for detecting tissue or body parameters comprising:

at least one light emitting source;

at least one photo-detector, wherein an optical isolator ring is placed around either the at least one light emitting source or the at least one photo-detector; and

an inflatable sleeve including the at least one light emitting source and the at least one photo-detector mounted thereon, the inflatable sleeve transitionable between a furled state and an unfurled state.

2. The intra-operative sensor device of claim 1, wherein the at least one photo-detector is placed within the optical isolator ring, and the at least one light emitting source surrounds the optical isolator ring.

3. The intra-operative sensor device of claim 1, wherein injection of inflation fluid into the inflatable sleeve transitions the inflatable sleeve to the unfurled state.

4. The intra-operative sensor device of claim 1, wherein the inflatable sleeve is biased toward the furled state.

5. The intra-operative sensor device of claim 1, wherein the inflatable sleeve is adapted and configured to be wrapped around the tissue.

6. An intra-operative sensor device for detecting tissue or body parameters comprising:

at least one photo-detector;

at least one light emitting source spaced radially from the at least one photo-detector, the at least one photo-detector detecting light backscattered from light emitted by the at least one light emitting source to detect parameters of the tissue or the body; and

an inflatable sleeve including the at least one light emitting source and the at least one photo-detector mounted thereon, the inflatable sleeve transitionable between a furled state and an unfurled state.

7. The intra-operative sensor device of claim 6, wherein the at least one light emitting source substantially encircles the at least one photo-detector.

8. The intra-operative sensor device of claim 7, further comprising an optical isolator ring positioned between the at least one photo-detector and the at least one light emitting source.

9. The intra-operative sensor device of claim 6, wherein the inflatable sleeve is biased toward one of the furled state or the unfurled state.
