1. An analysis method for a surgical operation via endoscopy at an operative site in a volume located inside a body, the method comprising:
- a) selecting the surgical operation to be performed;
b) detecting from an image of the operative site at least one instrument present therein,c) detecting from the image of the operative site at least one portion of an organ in the vicinity of the detected instrument,d) 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,e) selecting in a database a conceptual surgical step corresponding to the detected surgical step of the selected surgical operation from the detected instrument, the detected portion of organ, and their relative positioning,f) comparing the parameters of the detected surgical step with the parameters defining the selected conceptual surgical step to determine the differences between these parameters,g) (i) comparing the parameters of the detected surgical step with the parameters of a step consisting of at least one past performed surgical step derived from at least one same surgical operation as the selected surgical operation performed previously from a different patient,(ii) wherein said at least one past performed surgical step derived from at least one same previous surgical operation from a different patient is stored in a database with the conceptual surgical steps to make a comparison,h) displaying an overlay image on the detected image from an endoscope showing a current position of the detected instrument and the detected organ, to indicate an optimal position of the instrument,i) automatically varying in real time the overlay image based at least on step (g); and

Abstract
The invention concerns an analysis method for a surgical operation via endoscopy performed at an operative site in a volume located inside the body of an animal, characterized in that it comprises the steps consisting of:
- detecting at least one instrument (1; 2; 3) present at the operative site,
- detecting at least one portion of an organ (4) in the vicinity of the detected instrument (1; 2; 3),
- determining the positioning of the detected instrument (1; 2; 3) relative to the detected organ (4), so that the detected instrument (1; 2; 3), the detected portion of organ (4) 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 to the detected instrument (1; 2; 3), the detected portion of organ (4) 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 the determined differences.

12. An analysis system for a surgical operation via endoscopy performed at an operative site in a volume located inside a body, comprising:
-
a) a database in which conceptual surgical steps and past performed surgical steps comprising surgical steps derived from previous specific surgical operations from a different patient(s) are stored, b) at least one detector adapted to detect on an image of the operative site at least one instrument present at the operative site, c) the at least one detector adapted to detect at least one organ in the vicinity of the detected instrument, d) a computer adapted to determine positioning of the detected instrument relative to the detected organ, e) the database being used to select a conceptual surgical step corresponding to a detected surgical step of the selected surgical operation in relation to the detected instrument, to the detected organ and to their relative positioning, f) the computer being adapted to compare parameters of the detected surgical step with parameters defining the selected conceptual surgical step, and to determine the differences between these parameters, g) the computer being adapted to compare the parameters of the detected surgical step with parameters of past performed surgical steps corresponding to the selected conceptual surgical step, and for fine-tuning the differences ascertained, h) a display adapted to provide information on the quality of the detected surgical step on the basis of determined differences; and i) the display also showing information related to at least one of;
(i) a number of the detected instruments present, (ii) a relative distance between the detected instruments, (iii) time spent in a vicinity of the detected organ, or (iv) a speed of surgical movements. - View Dependent Claims (13, 14, 15, 16, 17)
