The utility model provides a print with 3D and exempt from to sew up identical support of courage intestines, these courage intestines of coincide that the support includes the support pipe and at the convex projection of support outside of tubes wall, are connected with the plush copper in both ends an organic whole of this support pipe, are connected with the drainage tube in the outer end of this plush copper, these courage intestines coincide the support be with biodegradable for the material 3D printing technique make. Wherein, the plush copper, it is globular to be the semicircle, the arc surface is to the both ends outsides. Wherein, it do not is equipped with projection from top to bottom to be close to both ends plush copper punishment at support outside of tubes wall. The beneficial effects of the utility model are that: its simple structure, convenient to use, effect are showing, the reconstruction of its image data data before according to the art, can use the 3D printing technique print out with the individual bile duct size of patient to the courage intestines that the mate support pipe that coincide, through these support pipes that has projection and plush copper, can realize exempting from to sew up identically to reduced and leaked and constrictive risk, simultaneously the greatly reduced operation degree of difficulty and risk.
