The present invention provides a surgical aspiration cannula capable of aspirating a liquid component such as a small amount of blood while keeping an ability to aspirate a large clot such as a blood clot and to sweep them. The present invention relates to a surgical aspiration cannula that comprises a tip opening capable of aspirating a clot such as a blood clot; and an aspiration structure in the front of the tip opening. Due to the aspiration structure, the liquid component such as a small amount of blood can be aspirated. Further, even when the tip opening is pressed against the vicinity of an organ, the aspiration structure interposed between an aspiration port and a surface of the organ prevents clogging of the cannula or damage to the organ. In addition, in a case of bleeding in a surgical site, the blood is aspirated while controlling the bleeding by pressurizing a bleeding site, thereby providing a clear view and enabling a hemostatic site to be treated.

A central electrode () and an outer electrode () 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 (). When the outer conductor () and the movable conductor () are relatively shifted in the axial direction, the central electrode () and the outer electrode () slidingly move on each other along the inclined direction, whereby a biotissue is cut between the central electrode () and the outer electrode ().

Medical treatment instrument and medical treatment apparatus including the same

A sheet material, coated with a surgical adhesive comprising an NCO-terminated urethane prepolymer, is used for bonding of tissues, with improved handleability. Surgical instruments, comprising a non-adherent material towards an NCO-terminated urethane prepolymer, are used for application of surgical adhesive. Such instruments, comprising a rod tapered so that the tip can be partly inserted into blood vessel, are suitable for anastomosis of blood vessel.
