Abstract

La présente invention concerne un mécanisme à came pour équipement médical de petite taille, en particulier un mécanisme de découpe à propulsion à came pour équipement médical de petite taille dans des hôpitaux ou des collectivités, comprenant un support (1), une came (2), une partie élastique et une tige de traction (6), un centre d'un cercle de base de la came (2) étant fixé de manière rotative au support (1), un dispositif de découpe (3) étant placé à proximité de la came (2), une extrémité de la partie élastique étant fixée sur le support (1), l'autre extrémité étant reliée au dispositif de découpe (3), la tige de traction (6) étant fixée à la came (2), la tige de traction (6) étant tirée pour entraîner la rotation d'une came (5), la came (5) poussant le dispositif de découpe (3) à se déplacer et à étirer ou à comprimer la partie élastique, et lorsque la tige de traction (6) est libérée, la partie élastique pousse le dispositif de découpe (3) à se déplacer jusqu'à une position initiale. Une tige de traction entraîne une came à pousser un dispositif de découpe pour couper un article à couper dans un processus de rotation, puis une partie élastique permet au dispositif de découpe de revenir dans une position initiale, de sorte que le mécanisme de découpe à propulsion à came a une plage d'applications très large et est approprié pour couper des comprimés ou des fils de coton, des tubes d'infusion et similaires.
