  • surgical-access tools such as for example tubular elements having different shape and size (for example having different opening diameters), which are able to exactly reproduce the real surgery accesses which are obtained by various types of pharyngo-laryngoscopes positioned through the oral cavity and held in place by suitable suspension systems.
  • surgical-access tools By interchanging the above described surgical-access tools, it is possible to modify the passageway to access the work area in which the exercise model is arranged, enabling also the reproduction of the different degrees of difficulty of the surgical procedure.
  • the invention comprises the following additional and optional features, taken individually or in combination if necessary.
  • the surgical-access tools may have a tubular shape with an inner passage which defines a through access channel, and wherein a diameter of the inner passage of a surgical-access tool is different from a diameter of the inner passage of another surgical-access tool of said plurality of surgical-access tools, different diameters corresponding to different difficulties of the exercise.
  • a diameter of the inner passage of a surgical-access tool is different from a diameter of the inner passage of another surgical-access tool of said plurality of surgical-access tools, different diameters corresponding to different difficulties of the exercise.

  • Figure 16B shows an arrangement of the exercise element 18 for a surgical technique with different accesses and horizontal suture; in this case, the integration of the exercise element 18 is with both the base element and with the covering element 13, wherein the upper part of the figure shows the holes for the correct impact angle, as well as the fastening positions P’ on the covering element 13.

Once inserted the elastic thread 25 into the holes, thanks to its elasticity and to the elastic grip of the bushing elements 16, it is possible to select the desired tension by pulling or loosening said elastic thread 25. It is noted that the elastic thread 25 itself can be considered part of the end of the exercise element 18.

Abstract

L'invention concerne un système (1) permettant d'effectuer des exercices pratiques de chirurgie, le système comprenant un élément de support (2), une pluralité d'outils d'accès chirurgical (3) qui peuvent être individuellement associés à l'élément de support (2) dans une position de travail (P), chacun desdits outils d'accès chirurgical (3) comprenant un corps à l'intérieur creux (3') qui s'étend le long d'un axe longitudinal (H-H) entre une première extrémité (3a) et une seconde extrémité (3b), et chacun desdits outils d'accès chirurgical (3) étant structuré de façon à simuler un laryngoscope pour chirurgie transorale et correspondant à un exercice ayant un certain degré de difficulté, ledit système comprenant également au moins un modèle d'exercice (4) disposé dans une zone de travail (A) du système (1) au niveau de la seconde extrémité (3b) de l'outil d'accès chirurgical (3) lorsque ce dernier est dans la position de travail (P), ledit modèle d'exercice (4) étant formé de façon à simuler une partie anatomique sur laquelle l'exercice doit être effectué. Chaque outil d'accès chirurgical de la pluralité d'outils d'accès chirurgical (3) peut être convenablement retiré de la position de travail (P) et remplacé par un autre outil parmi lesdits outils d'accès chirurgical (3) dans ladite position de travail (P), ce qui permet de faire varier le degré de difficulté de l'exercice.
