Summary:The invention discloses a 3D nail groove structure of a circular anastomat. The structure comprises a nail abutting base body, an anastomosis surface is arranged at the bottom end of the nail abuttingbase body, a plurality of nail grooves are formed in the anastomosis surface, protrusions which are symmetrically distributed are arranged at the two ends of each set of nail grooves, multiple sets of nail grooves are evenly distributed around the central axis of the nail abutting base body, and the bottom end of the nail abutting base body is provided with a connecting cylinder. The nail groovesare designed to be of a crossed nail groove structure, suturing nails are bent into a 3D curved surface along the crossed nail grooves to be formed in a crossed mode, control over tension generated when tissue is too thick is facilitated, and suturing safety is guaranteed. Meanwhile, the arranged number of the suturing nails in the 3D shape is smaller than that of traditional 2D nails, so that the number of the suturing n
