A pair of hole punching pliers, so-called stoma pliers, is arranged to punch a hole in a skin protection plate for a stoma bag. The hole punching remedies of the pliers consist of a hole socket (16) and a holding-up plate (18) for the same. During the punching, a plastic skin protection plate is located between the hole socket (16) and the opposing surface of the holding-up plate (18), as the free, outer cutting/punching edge (22) of the hole socket (16) after the completion of the punching abuts directly on said opposing holding-up plate surface. To achieve an optimal punching operation, which is dependant upon the hole socket's (16) outer punching edge part (22) being placed maximally perpendicularly on said holding-up plate surface, at the same time as this surface should be able to dislocate (turning eccentrically) in relation to the wearing effect of said outer punching edge part on the surface of the holding- up plate by its abutments against same at the completion of each hole punching, at least the hole socket (16) has pivotal bearing around a lateral axis (24), which is arranged perpendicularly on its symmetrical axis (26), which in its closed position at the completion of each hole punching runs eccentrically in relation to the symmetrical axis (30) of the holding-up plate (18), which said symmetrical axis forms the pivotal axis of the holding-up plate (18).
L'invention concerne une paire de pinces de perforation, dénommées pinces pour stomie, destinées à pratiquer un trou dans une plaque de protection cutanée d'une poche pour stomie. Les dispositifs de perforation des pinces consistent en une douille (16) de perforation et une plaque (18) de retenue. Lors de la perforation, une plaque de protection cutanée en plastique est disposée entre la douille (16) de perforation et la surface opposée de la plaque (18) de retenue, le rebord (22) libre de coupe/perforation extérieur de la douille (16) de perforation butant directement sur la surface opposée de la plaque de retenue après la perforation. Pour obtenir une perforation optimale, qui dépend du placement perpendiculaire maximal du rebord (22) de perforation extérieur de la douille (16) de perforation sur la surface de la plaque de retenue, et de la capacité de cette surface de se déformer (par rotation excentrique) en fonction de l'effet d'usure exercée par le rebord de perforation extérieur sur la surface de la plaque de retenue en butant contre elle à chaque perforation, au moins la douille (16) de perforation est dotée d'un support pivotant autour d'un axe latéral (24) perpendiculaire à son axe symétrique (26), qui dans sa position fermée après chaque perforation se déplace symétriquement par rapport à l'axe symétrique (30) de la plaque (18) de retenue, cet axe symétrique formant l'axe pivotant de la plaque (18) de retenue.
