Abstract

The invention relates to a method for analysing a surgical operation by endoscopy in an operation field in a space inside the body of an animal, characterised in that it comprises the steps of: detecting at least one tool (1, 2, 3) present in the operation field; detecting at least one portion of an organ (4) in the vicinity of the detected tool (1, 2, 3); determining the position of the detected tool (1, 2, 3) relative to the detected organ (4) so that the detected tool (1, 2, 3), the detected portion of the organ (4) and their relative positioning form parameters defining a detected operation field; selecting, in a database, a conceptual field of operation corresponding to the detected operation field based on the detected tool (1, 2, 3), the detected portion of the organ (4), and their relative positioning; comparing the parameters of the detected field of operation with the parameters defining the selected conceptual field of operation in order to determine the deviations between said parameters; providing information on the quality of the detected field of operation based on the determined deviations.

Claims

1. An analysis method for a surgical operation via endoscopy at an operative site in a volume located inside the body of an animal, said method comprising:

detecting at least one instrument present in the operative site,

detecting at least one portion of an organ in the vicinity of the detected instrument,

determining the positioning of the detected instrument relative to the detected organ, so that the detected instrument, the detected portion of organ, and their relative positioning form parameters defining a detected surgical step,

selecting in a database a conceptual surgical step corresponding to the detected surgical step from the detected instrument, the detected portion of organ, and their relative positioning,

comparing the parameters of the detected surgical step with the parameters defining the selected conceptual surgical step to determine the differences between these parameters,

providing information on the quality of the detected surgical step on the basis of determined differences.

2. The method of claim 1, wherein said method is applied during the surgical operation to provide real time assistance.

3. The method of claim 1, wherein said method is applied after the surgical operation to permit retrospective analysis of the surgical operation carried out.

4. The method of claim 1, wherein the parameters of the detected surgical step are also compared with the parameters of past performed surgical steps derived from previous surgical operations and stored in the database with the conceptual surgical steps to make a comparison, said comparison being intended to fine-tune the differences ascertained with the past performed surgical step(s) so as to give more precise information on the quality of the detected surgical step.

5. The method of claim 1, further comprising selecting in the database a surgery protocol comprising a succession of surgical steps with a view to performing a surgical operation, the selected surgery protocol corresponding to the surgical operation being performed and to a succession of detected surgical steps.

6. The method of claim 5, wherein the surgery protocol is also selected based on parameters characteristic of the animal, which may have an impact on conducting of the surgical operation.

7. The method of claim 5, wherein the information on quality comprises depiction of the required position of the instrument relative to the portion of organ as per the selected conceptual surgical step and the selected surgery protocol.

8. The method of claim 7, wherein the information on quality comprises depiction of the instrument as an overlay over an image of the operative site, showing the required position of the instrument relative to the portion of organ.

9. The method of claim 5, further comprising selecting in the database a succeeding past performed surgical step which, in the selected surgery protocol, follows after the detected surgical step, and displaying a depiction of said succeeding past performed surgical step.

10. The method of claim 5, wherein the additional information comprises triggering an alert if the last detected surgical step does not allow selection of a conceptual surgical step corresponding to the surgical operation being performed and to the succession of previous surgical steps.

11. The method of claim 1, wherein an endoscopic imaging technique is used for detection of the instrument and/or detection of the portion of organ.

12. The method of claim 11, wherein, for detection of the portion of organ, a labelling substance to label said organ is used, said substance containing a fluorescent substance and antibodies specific to the organ, the endoscopic camera being adapted for the band of fluorescence wavelengths of the labelling substance.

13. An analysis system for a surgical operation via endoscopy performed at an operative site in a volume located inside the body of an animal, comprising:

a database in which conceptual surgical steps are stored,

means to detect at least one instrument present at the operative site,

means to detect at least one organ in the vicinity of the detected instrument,

means to determine the positioning of the detected instrument relative to the detected organ,

means to select, in the database, a conceptual surgical step corresponding to a detected surgical step in relation to the detected instrument, to the detected organ and to their relative positioning,

means to compare the parameters of the detected surgical step with the parameters defining the selected conceptual surgical step, and means to determine the differences between these parameters,

means to provide information on the quality of the detected surgical step on the basis of determined differences.

14. The system of claim 13, wherein the database comprises means to store surgery protocols, a surgery protocol being a succession of surgical steps with a view to performing a surgical operation, the system further comprising means to select, in the database, a surgery protocol corresponding to the surgical operation being performed, and to a succession of detected surgical steps.

15. The system of claim 14, wherein the means to provide information on quality comprise means to indicate the required position of the instrument relative to the portion of organ as per the selected conceptual surgical step and the selected surgery protocol.

16. The system of claim 15, wherein the means to provide information on quality further comprises means to display a depiction of the instrument as an overlay over an image of the operative site, showing the required position of the instrument relative to the portion of organ.

17. The system of claim 13, further comprising means to select, in the database, a succeeding past performed surgical step which, in the selected surgery protocol, follows after the detected surgical step, and the means to provide information on quality further comprises means to display a depiction of said succeeding past performed surgical step.

18. The system of claim 13, wherein the means to provide additional information comprises means to trigger an alert if the last detected surgical step does not allow selection of a conceptual surgical step corresponding to the surgical operation being performed and to the succession of prior surgical steps.
