Definitions

  • the invention relates generally to an interactive medical training system.
  • US 6,131,097 shows a haptic/visual authoring tool comprising a disclosure of controlling an avatar interacting with a virtual object, generating responsive forces.
  • the present invention relates on the insight that a method for training a user in a medical procedure has to divide the training session into smaller parts, that the user should be able to start every of these parts repeatedly in an environment of a perfectly completed former part, that the method has to guide the user within the different steps, and that the method has to provide an assessment at the end of a completed training session clearly showing the results and especially possible weaknesses of the user in view of further training sessions.
  • the result (i.e. the assessment) of a training session is available for a supervisor of the training session in connection with a stored session history to be able to evaluate the errors together with the user at any later moment .
  • Fig. 3 shows a screen display showing different sub-steps of a step according to Fig. 2, and
  • Fig. 4 shows a schematic view of another virtual organ with further graphical identification markers .
  • Fig. 1 shows a schematic view of an organ 1 together with two instruments 2 and 3 as it is generated on a screen visible to the user in the training session. Said representations of organ
  • Fig. 2 shows a screen display of different steps of the training session available in connection with the simulated treatment of the organ 1 according to Fig. 1.
  • this surgical interaction may comprise: step 51: gripping' of the organ in the area 4 with instrument
  • step 52 setting clips in the area 5 with help of the instrument 3 , and. step 53: cutting a vessel in an area 7.
  • the training is separated into different training steps 51 to 53.
  • the different steps 51 to 53 can be chosen independently from a menu as shown in Fig. 2.
  • the menu comprises a step 50: information about the virtual patient, step 55: tutored intervention of all steps 51 to 53 within one step, step 56: complete "free" intervention of all steps 51 to 53 within one step, and step 57: assessment of the training session.
  • Further steps for maintenance .of the user information, storing or retrieving parameters for the intervention e.g. parameters of the virtual patient, surgical problems arising with said patient, etc.
  • storing or retrieving of different training sessions e.g. for later assessment
  • sub-step 62 a prerecorded virtual reality video representation of the intervention to be performed within said step 51 or
  • sub-step 63 instructions for the intervention of said step 51 or 52 or 53
  • sub-step 64 a prerecorded virtual reality graphical (stills) or video representation of common errors within said step 51 or 52 or 53, which can usually be picked from a further listing submenu
  • sub-step 65 training session of the step in question with guidance
  • sub-step 66 training session of the step in question without guidance.
  • the graphical representation comprises a direct correlation with the action of the instrument handled by the user. This can be shown within the embodiment of the intervention as follows .
  • step 52 "clipping” the user has to move the instrument 2 towards the organ 1 and grip it in an area 4 (same procedure as in the step 51 "gripping") . Then he has to hold the organ 1 in a certain position and to apply three clips in the two areas 5 (in order to enable the cutting of the vessel in step 53 "cutting" between the clips in area 7) .
  • the step 52 "clipping” asks the user to put three clips into predefined positions, which are marked 15A, 15B and 15C.
  • the necessity to apply the same number of clips to the second vessel in the background is not treated within this simplified approach of the description.
  • the ring 15A is blue.
  • the user virtually loads a clip 13 into instrument 3 and approaches the blue ring 15A.
  • the blue ring 15A becomes green.
  • the ring may become yellow or red.
  • the color red is associated with a hazardous situation and yellow a situation which is not correct according to the teached procedure but not "dangerous" for the virtual patient.
  • next ring here 15B or 15C becomes blue and the process is repeated until all clips are set. Then all areas 14, 15A to 15C which are shaded in the drawings and which should be green vanish as indication that the step is completed.
  • Fig. 4 shows a schematic vie ' of another virtual organ 1 with further graphical identification markers 18A, 18B and 19.
  • Organ 1 has a cylindrical form.
  • a blue line 18A is appearing on the organ.
  • This line 18A has preferably a starting point and an end point which can be seen through enlarged dots.
  • the relevant part of the line 18A turns green. If the user burns the area or enters the instrument too deep into the organ, then beside the effect of the virtual representation showing the results of this treatment (smoke, burned points, bleeding) this part of the line turns red.
  • the line and the dots turns into green and the next segment 18B is lit up in blue colour. This advises the user where to continue his task until the related step is completed.
  • Area 19 shows a region in which the user has to open the surface within a larger area.
  • the area to be opened is blue and all cut off pieces will loose there blue color and turn green.
  • the whole area will have green borders and then the marker areas will vanish.
  • the concept of guidance is to project a (two-dimensional) surface area information in the area which has to be treated through the user in training.
  • This may be a larger spot, as spot 14 for a gripping action.
  • This may be a ring, as ring 18A for the clipping action.
  • This may be a line or a segment of a line as lines 18A and 18B for marking or cutting purposes.
  • this can be of any geometrical form as polygon 19 which marks the area which has to be treated.
  • the correlation between the instrument and the graphical representation is immediate and gives a direct visual assessment in the training. In case of the line it had been shown that it is possible to directly show the three states: a.) parts still to be treated are in blue b.) parts which have been correctly treated are in green and c .
  • parts which has been maltreated are in red (or yellow) . Beside the possibility to show the errors in color they can also be ex- plained through text which are correlated to the errors through a suitable table. Such a direct computer calculated assessment gives the user the opportunity to correct and ameliorate his performance in one or more of the steps before trying the final (not guided) stage of the intervention.

Abstract

L'invention concerne un procédé de formation d'un utilisateur à une procédure médicale utilisant un système informatique interactif avec représentation virtuelle d'au moins un organe (1) et d'au moins d'un instrument (2, 3). La représentation de parties de zones de surface (4, 5, 7, 8, 9) de l'organe virtuel (1) à traiter est couverte de repères graphiques d'identification (14, 15A à 15C, 17). Le système informatique comprend un tableau stocké en mémoire contenant des situations surgissant dans des procédures médicales définies par des positions des instruments (2, 3), des positions de l'organe (1), la séquence logique des étapes à exécuter dans cette procédure médicale, les valeurs différentes d'aspect des repères graphiques d'identification (14, 15A à 15C, 17) et les valeurs d'évaluation de la situation. Lors de l'interaction de l'utilisateur avec l'organe (1) et l'instrument (2, 3), un ou plusieurs repères graphiques d'identification (14, 15A à 15C, 17, 18A + 18B, 19) changent leur aspect selon la valeur stockée dans le tableau concernant la situation définie et la valeur d'évaluation correspondante est stockée dans un tableau d'archives dans le système informatique.
