A tissue closure device (30), a tissue closure component, and a medical equipment. The tissue closure device (30) comprises a base (303), a pressure plate (305) configured to match the base (303), and a stapling plate (307). The pressure plate (305), provided so as to rotate relative to the base (303), comprises an opened position and a closed position. When the pressure plate (305) is in the closed position, the pressure plate (305) and the base (303) form a first accommodating space (401) capable of accommodating a part of a tubular tissue. The stapling plate (307) includes a starting position and a staple closing position. The starting position is located at a proximal end of the first accommodating space (401) relative to the staple closing position. The tissue closure device (30) also comprises a stapling portion (309). The stapling portion (309) is provided at a distal end of the base (303) and is used to place a closure staple (50). The stapling plate (307) and the stapling portion (309) are provided with a structure enabling the two to drive in cooperation to cause the deformation of the closure staple (50) located at the stapling portion (309). The tissue closure device (30) forms a cluster of pockets towards the center, thereby minimizing risks of tissue infection and surgical costs during subsequent use of a circular vessel anastomotic device.La présente invention concerne un dispositif de fermeture tissulaire (30), un élément de fermeture tissulaire et un équipement médical. Le dispositif de fermeture tissulaire (30) comprend une base (303), une plaque de pression (305) conçue pour s'adapter à la base (303) et une plaque d'agrafage (307). La plaque de pression (305), disposée de façon à tourner par rapport à la base (303), comporte une position ouverte et une position fermée. Lorsque la plaque de pression (305) est dans la position fermée, la plaque de pression (305) et la base (303) forment un premier espace de logement (401) pouvant accueillir une part
