Abstract

L'invention concerne entre autres un dispositif d'accouplement (40) pour un instrument chirurgical présentant un circuit de rinçage, en particulier pour une tête de résection. Le dispositif d'accouplement (40) présente respectivement un élément d'accouplement pour une conduite d'entrée de rinçage (44) et un élément d'accouplement pour une conduite de sortie de rinçage (46). Lors de la connexion, l'élément d'accouplement pour la conduite d'entrée de rinçage (44) coopère avec un élément de raccordement, en particulier amovible, pour la conduite d'entrée de rinçage (54), et l'élément d'accouplement pour la conduite de sortie de rinçage (46) coopère avec un élément de raccordement, en particulier amovible, pour la conduite de sortie de rinçage (56). L'élément d'accouplement pour la conduite d'entrée de rinçage (44) et l'élément d'accouplement pour la conduite de sortie de rinçage (46) sont réalisés différemment, de sorte que l'élément d'accouplement pour la conduite d'entrée de rinçage (44) coopère exclusivement avec l'élément de raccordement pour la conduite d'entrée de rinçage (54) et que l'élément d'accouplement pour la conduite de sortie de rinçage (46) coopère exclusivement avec l'élément de raccordement pour la conduite de sortie de rinçage (56). L'invention concerne par ailleurs un dispositif de raccordement (50) destiné à un dispositif d'accouplement (40) d'un instrument chirurgical présentant un circuit de rinçage.
