An organ container includes a bag-shaped or tube-shaped insulating sheet. The insulating sheet has an opening and is capable of containing an organ inserted in an inner space through the opening. The insulating sheet is formed of an extra flexible material. The insulating sheet has a hardness less than or equal to F45 according to a durometer hardness test compliant with JIS K 6253-3:2012. Accordingly, in the transplantation of an organ with a variety of sizes and shapes into a recipient, the organ container is capable of covering the surface of the organ along the surface of the organ while holding the organ. The organ container suppresses a further outward spread of the organ, thereby ensuring the field of operation and reducing the possibility of interfering with the work of a surgeon.

An anastomosis assist tool comprises a body unit extending in a predetermined advancing direction, and an insertion unit arranged at the tip of the body unit. The body unit includes an anastomosis assist part having an approximately constant cross-sectional shape in a plane perpendicular to the advancing direction. The anastomosis assist part includes a projection projecting outwardly as viewed in the cross section and extending in the advancing direction. The insertion unit includes a tapered part of a diameter decreasing gradually toward a tip. When the insertion unit and a part of the body unit are inserted into a vessel, the projection of the anastomosis assist part of the body unit abuts on the inner wall of the vessel. This makes it unlikely that the inner wall of the vessel will stick to the body unit at a site other than a point abutting on the projection.

An organ container includes a bottomed tubular outer container and a bottomed tubular inner container that is fitted into the outer container. A fluid flow path is formed between an outer peripheral surface of the inner container and an inner peripheral surface of the outer container. The outer container has an inlet that communicates between the fluid flow path and the outside, and an outlet that communicates between the fluid flow path and the outside.

An organ container includes flexible films and a tube holder. The films hold an organ in contact with the surface of the organ. The tube holder holds tubes that extend between the organ in the films and an outside of the films. This makes it possible to hold and preserve the organ while allowing a liquid to be perfused through the organ via the tubes. It is also possible to reduce movements of the organ relative to the organ container and to reduce damage to the organ.

A frame includes a ring-shaped body part locatable to surround the periphery of an organ, and at least one tube clamp part mounted on the body part. Each tube clamp part includes a tube holder that holds a tube. The tube clamp part is mounted so as to be movable in the circumferential direction of the body part. Thus, a tube connected to the organ can be fixed at an appropriate position to the tube clamp part. This stabilizes the relative positions of the organ and the tube. Accordingly, it is possible to reduce the probability of the organ becoming damaged due to a strain on the organ.
