Abstract: This organ protecting member (1) is used when an opening portion (36a) is formed in an abdominal wall (30) and an intestinal tract (32) is exposed to a body surface (33) from the opening portion (36a) to temporarily construct an artificial anus (34). The organ protecting member (1) includes a movement restricting part (support string (12)) configured to restrict movement of a portion of the lifted intestinal tract (32) on which the artificial anus (34) is constructed toward an abdominal cavity (35); and a cover (11) disposed between the intestinal tract (32) and an inner wall surface (36b) of the opening portion (36a) of the abdominal wall (30).

Abstract: A medical treatment implement which has an excellent degree of freedom of a procedure and into which a trocar can be re-stuck includes a tubular retractor main body configured to be indwelled in an incision wound and a converter (20) configured to close an opening end portion of an upper end of the retractor main body and to be puncturable with a trocar. The converter (20) includes a ring-shaped frame portion (22) detachably mounted on the opening end portion and a sheet portion (21) which is mounted inside the frame portion (22) and airtightly covers the opening end portion. A compression force P is applied to the sheet portion (21) in an inner diameter direction.

Abstract: An adhesive applicator for biological tissue (100) includes a nozzle body (1), a gas inlet (2), medical fluid inlets (3a, 3b), medical fluid outlets (4a, 4b), medical fluid tubes (5a, 5b), a gas outlet (6), communication paths (8a, 8b), and a check valve (7b). The gas outlet (6) is located close to the medical fluid outlets (4a, 4b), and configured to eject gas loaded through the gas inlet (2) in the nozzle body (1) to thereby atomize medical fluids and mix them together. The communication paths (8a, 8b) communicate between inside of the nozzle body (1) and inside of the medical fluid tube (5b). The check valve (7b) is located between the communication paths (8a, 8b) and the medical fluid inlet (3b). The check valve (7b) only allows one-way flow of the medical fluid from the medical fluid inlet (3b) into the medical fluid tube (5b).

Abstract: An endoscopic ligation kit including an inner cylinder, an outer cylinder having at least two step portions of diminishing outer radii formed on the outer periphery of its distal end portion, and a slide cylinder provided between the inner cylinder and the outer cylinder. The outer cylinder has a notch extending from its distal end portion to its maximum outer diameter portion. The slide cylinder has at its distal end portion a projection which conforms in size to the notch, and has steps and the projection is fitted in the notch. O-rings are mounted respectively on the outer periphery of the distal end portion of the inner cylinder and the step portions of the outer cylinder.
