    摘要： A steerable catheter includes a flexible tube having a distal end and a proximal end. The tube includes a first tube section (sheath body section) the flexibility of which does not substantially change even upon receiving compression force in the axial direction; and a second tube section (deflection section) joined so as to be continuous with the distal end of the first tube section and constituted by a porous tube becoming hard upon being compressed according to the degree of the compression force acting in the axial direction and returning to being soft when the compression force is released. The tube includes operation means (wires) for releasably exerting a compression force compressing the second tube section in the axial direction and a deflection force deflecting the second tube section. According to some embodiments, both operability and insertability of the steerable catheter can be improved.

    摘要： A movable catheter is provided with a tube having a main lumen. The tube has a plurality of wire lumens and is provided with a wire. A substantial half on one end portion side thereof is inserted through the wire lumen, an intermediate part thereof is folded back in the distal end portion of the tube, and a substantial half on the other end portion side thereof is inserted through the wire lumen. The one end portion and the other end portion thereof are disposed on the proximal end side of the tube. Various embodiments enable the number of components to be reduced, and to reduce the number of manufacturing steps.

    摘要： 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.

    摘要： Provided is a surgical instrument that is substitutable for an operation of placing each stitch with a threaded needle or a stapler. It is confirmed that, in a tissue suturing device including a clamping section, and a protruding section including a central conductor and/or an external conductor for applying a microwave, the protruding section and the clamping section bring fragmentary portions of tissues to be sutured into contact or overlap with each other, and coagulate and/or fix contact or overlap portions with the microwave, to thereby stitch the tissues to be sutured.

    摘要： Provided is an operating tool for organism, in particular, a microwave endoscope forceps. In terms of the operating tool for organism, provided is a multifunctional operating tool which has holding and scissors functions simultaneously, and may further perform coagulation (tissue fixation) by microwaves. The operating tool has no definite fulcrum, and has both the holding and scissors functions with a simple structure by deforming a long-track rod called beam. Two blades are insulated from each other so as to allow microwave current supply. With this structure, an operating tool having three functions, i.e., “a holding function”, “a coagulating function”, and “a cutting function” with a single tool may be developed.

    摘要翻译： 本发明提供一种生物体的操作工具，特别是微波内窥镜镊子。 就生物的操作工具而言，提供了一种多功能操作工具，其具有同时保持和剪刀功能，并且可以进一步通过微波进行凝固（组织固定）。 操作工具没有明确的支点，通过使称为梁的长轨杆变形，具有简单结构的保持和剪刀功能。 两个叶片彼此绝缘，以便允许微波电流供应。 利用这种结构，可以开发具有单个工具的具有三个功能即“保持功能”，“凝结功能”和“切割功能”的操作工具。
