An umbilical cord cutter, comprising a push-cut rod (5), a clamping seat (4), a mother-side clamp (1), and an infant-side clamp (2) a blade (3) is installed at one end of the push-cut rod (5) a poking sheet (5-1) is arranged on one side surface to coordinate with the infant-side clamp (2), and a slide rail (5-3) is arranged on the other side surface the clamping seat (4) consists of a bottom plate (4-7) and a slide cavity (4-6) the push-cut rod (5) is inserted into the slide cavity (4-6) on the clamping seat (4) the bottom plate (4-7) of the clamping seat (4) is connected to the mother-side clamp (1) and the infant-side clamp (2) the upper and lower inner walls of the slide cavity (4-6) are respectively provided with an upper and a lower chutes (4-4, 4-5) thereon to slidably cooperate with the push-cut rod (5) a bump (2-4) is fixed at the opening end of the lower arm of the infant-side clamp (2) to coordinate with a blind hole (4-8) on an inner wall at one end of the bottom plate (4-7) of the clamping seat the push-cut rod (5) linearly moves in the upper and lower chutes (4-4, 4-5) in the slide cavity (4-6) without wobbling, thus being safe to use and improving the cutting force. The mutual cooperation between the blind hole (4-8) and the bump (2-4) on the infant-side clamp (2) is added, such that the infant-side clamp (2) will not be pushed out of the clamping seat (4) before cutting, thus ensuring absolute safety. The present invention is safer to use, and saves labor, thus facilitating the operation of medical care personnel.Linvention concerne un élément de coupe de cordon ombilical, comprenant une tige de coupe par poussée (5), un siège de serrage (4), une pince côté mère (1) et une pince côté nourrisson (2) une lame (3) est installée sur une première extrémité de la tige de coupe par poussée (5) une feuille denfoncement (5-1) est agencée sur une surface latérale de façon à être coordonnée avec la pince côté nourrisson (2), et un rail coulissant (5-3) est age
