Abstract

La présente invention se rapporte à un porte-dispositif de retenue d'organe pour la chirurgie endoscopique. Le porte-dispositif de retenue d'organe de la présente invention permet de retenir un organe corporel de façon plus stable que des forceps classiques destinés à être utilisés en chirurgie endoscopique afin d'améliorer facilement la visibilité de la partie du corps sur laquelle on est en train d'intervenir chirurgicalement et permet d'effectuer des interventions chirurgicales en douceur. En outre, le porte-dispositif de retenue d'organe de la présente invention permet à un chirurgien en train d'opérer d'effectuer une intervention chirurgicale d'une manière commode en éliminant le besoin de tenir le porte-dispositif de retenue d'organe avec les mains une fois que les organes corporels sont retenus par le porte-dispositif de retenue d'organe. Le porte-dispositif de retenue d'organe de la présente invention utilise un trocart dans lequel passe une bague d'un fil de tension, le trocart ayant un diamètre extrêmement petit pour éviter ou réduire la cicatrice sur une partie du corps d'un patient après l'intervention chirurgicale.
