Abstract: A bending and extending device 1 comprises an elastic hollow guide unit 2 and a movable part 3 to be movably inserted into the guide unit 2. The movable part 3 is constituted, either partially or entirely, of a plurality of belt-like flexible parts 30a and 30b, which extend in the axial direction of the guide unit 2 and the flexible parts 30a and 30b are connected at distal ends. The bending and extending device 1 is characterized in that, when, by the sliding operation of the flexible parts 30a and 30b, a cross-section in which a contact point T of the flexible part 30a and the inner surface of the guide unit 2 is present on an extending line Y extending from a line segment connecting the centroid P of the flexible part 30b and the axial center G of the guide unit 2 and in which the flexible part 30a and the second flexible part 30b are in contact with each other is generated, and when the cross-section is divided into two ranges by a predetermined straight line X, the centroid P of the flexible part 30b is not positioned in a range in which the contact point T is present; and the predetermined straight line X is a line that passes through the axial center G of the guide unit 2, and that orthogonally crosses the extending line Y.

Abstract: It is an object to provide a surgical tool for excising a hard solid organ such as cirrhotic liver or cutting the organ into a groove without causing bleeding. The inventors of the present invention have found that an organ resection tool including a brush-like structure capable of performing microwave irradiation and/or a brush-like structure capable of receiving a microwave can achieve the above-mentioned object, to thereby arrive at the present invention (organ resection tool including a brush structure capable of performing microwave irradiation). For example, an organ can be crushed or scraped away by manually abrading the organ with a brush of a solid organ resection tool including a brush structure capable of performing microwave irradiation according to the present invention. Further, the organ can be concurrently coagulated through the microwave irradiation to stop bleeding.
Abstract translation: 本发明的目的是提供一种用于切除硬固体器官如肝硬化肝脏或将器官切割成凹槽而不引起出血的外科手术工具。 本发明的发明人已经发现，包括能够进行微波照射的刷状结构和/或能够接收微波的刷状结构的器官切除工具可以实现上述目的，从而达到 本发明（包括能够进行微波照射的刷结构的器官切除工具）。 例如，可以用包括能够进行根据本发明的微波照射的刷结构的实体器官切除工具的刷子手动研磨器官来将器官压碎或刮掉。 此外，器官可以通过微波照射同时凝结以止血。
