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 a sensor including one or more light emitting sources and one or more photo-detectors, wherein an optical isolator ring is placed around either the one or more light emitting sources or the one or more photo-detectors.

2. The intra-operative sensor device of claim 1. wherein the one or more light emitting sources is placed within the optical isolator ring, and the one or more photo-detectors radially surround the optical isolator ring and the one or more light emitting sources that are placed within the optical isolator ring.

3. The intra-operative sensor device of claim 1, wherein the one or more photo-detectors is placed within the optical isolator ring, and the one or more light emitting sources surround the optical isolator ring and the one or more photo-detectors that are placed within the optical isolator ring.

4. The intra-operative sensor device of claim 1, further comprising a member in which the sensor is operatively mounted, the member movable between a furled state and an unfurled state.

5. The intra-operative sensor device of claim 4, wherein the member includes an inflatable sleeve, wherein injection of inflation fluid moves the member to the furled state.

6. The intra-operative sensor device of claim 4, wherein the member is biased to the furled state.

7. The intra-operative sensor device of claim 4, wherein the member is adapted and configured to be wrapped around tissue.

8. The intra-operative sensor device of claim 1, wherein the sensor is operably coupled to a laparoscopic device.

9. The intra-operative sensor device of claim 8, wherein the laparoscopic device includes an elongated shaft having a distal end, and an end effector including first and second jaw members.

10. The intra-operative sensor device of claim 9, wherein the one or more light emitting sources are mounted on the first jaw member.

11. The intra-operative sensor device of claim 9, wherein the one or more photo detectors are mounted on the second jaw member.

12. The intra-operative device of claim 8, wherein the laparoscopic device includes an elongated shaft having a distal end, and wherein the sensor is operatively coupled into the distal end of the elongated shaft.

13. An intra-operative sensor device for detecting tissue or body parameters comprising one or more photo-detectors and one or more light emitting sources spaced radially from the one or more photo-detectors, the one or more photo-detectors detecting light backscattered from the light emitted by the one or more light emitting sources to detect parameters of the tissue or body.

14. The intra-operative sensor device of claim 13, wherein the one or more light emitting sources substantially encircle the one or more photo-detectors.

15. The intra-operative sensor device of claim 14, further comprising an optical isolator ring positioned between the one or more photo-detectors and the one or more light emitting sources.

16. The intra-operative sensor device of claim 13, wherein the one or more photo-detectors substantially encircle the one or more light emitting sources.

17. The intra-operative sensor device of claim 16, further comprising an optical isolator ring positioned between the one or more photo-detectors and the one or more light emitting sources.
