Abstract: Microwave-irradiating surgical instruments for endoscopic forceps or scope-assisted surgery forceps that have long lead wires often generate heat even during microwave transmission and a water supply device for cooling is necessary. Accordingly, conventional surgical instruments that irradiated energy such as microwaves had a separate passage for passing water (a water supply device) inside the forceps or endoscope. Due to the space occupied by said water supply device, the image cable or work hole diameter could not be enlarged. Moreover, the presence of the water supply device made surgery difficult. The present invention was completed by the discovery that a microwave-irradiating instrument wherein the central conductor is hollow and forms a channel and said channel is used as a water supply tube, etc. solves the above problems without affecting microwave irradiation efficiency.

Abstract: The solution of the problem to be solved is the provision of a means for determining timing both accurately and securely at which a treatment is shifted from gripping and coagulation (hemostasis or sealing) to resection by using a multifunctional treatment tool capable of exfoliation, gripping, coagulation (hemostasis or sealing) and resection of the treated region in a bipolar microwave treatment tool. A microwave surgical device control method and a device, in which the completion of coagulation (hemostasis or sealing) of tissue is detected and a microwave oscillation output is controlled by making use of the change in the direct current electric resistance value due to the reduction in the amount of water as the temperature rise of the tissue at the time of heating and coagulation of the tissue in the treated region with microwaves.

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: 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.

Abstract: It is an object to provide a surgical instrument capable of locally applying microwaves to a minute biological tissue. It has been found that microwaves can be transmitted to a tip of a tapered coaxial body (9) and that microwaves are radiated from the entire central conductor exposed in a major axis direction by decreasing a sectional area (preferably diameter) of a central conductor (1) and a sectional area (preferably inner diameter) of an external conductor gradually or in a step-by-step manner with a ratio between the sectional area (diameter) of the central conductor (1) and the sectional area (inner diameter) of the external conductor being set to be constant, thereby achieving the present invention.

Abstract: 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.

Abstract: In order to reliably cut off a living tissue by using a microwave in a surgical operation without causing excessive damage to the living tissue or without bleeding, it is necessary to suppress energy attenuation until the microwave reaches electrode blades for nipping, coagulating, and cutting off a tissue. However, it is difficult to suppress the energy attenuation. The present invention relates to a medical treatment device capable of reliably cutting off a living tissue by using a microwave while sealing vasculature by coagulating the living tissue without excessively damaging the living tissue. Specifically, the present invention relates to a medical treatment device including a movable first electrode blade connected to an external conductor and a fixed second electrode blade connected directly to a central electrode.

Abstract: The present invention provides a surgical suction cannula capable of sucking a liquid component such as a small amount of blood while keeping an ability to suck a large clot such as a blood clot and to sweep them. The present invention relates to a surgical suction cannula, including: a tip opening capable of sucking a clot such as a blood clot; and a suction structure in the front of the tip opening. Due to the suction structure, the liquid component such as a small amount of blood can be sucked. Further, even when the tip opening is pressed against the vicinity of an organ, the suction structure interposed between a suction port and a surface of the organ prevents choke between the organ and the cannula or damage to the organ due to choke by suction. In addition, in a case of bleeding in a surgical site, the blood is sucked while controlling the bleeding by pressurizing a bleeding site, to thereby provide a view enabling a hemostatic site to be treated.

Abstract: A central electrode (12a) and an outer electrode (16a) are arranged in such a manner that their top end portions are inclined in the same direction with respect to the axial direction of the outer conductor (14). When the outer conductor (14) and the movable conductor (16) are relatively shifted in the axial direction, the central electrode (12a) and the outer electrode (16a) slidingly move on each other along the inclined direction, whereby a biotissue is cut between the central electrode (12a) and the outer electrode (16a).
