TUBULAR TISSUE ANASTOMOTIC INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a tubular tissue anastomotic instrument capable of sharply enhancing operation efficiency and capable of suppressing the necrosis of cells present in the surface layer part of the outer peripheral surface of tubular tissue while lowering the dependence degree on the manipulation level of an operator to the utmost. SOLUTION: The tubular tissue anastomotic instrument 1 includes an outside anastomotic member 10 and the inside anastomotic member 20 arranged inside the outside anastomotic member 10 to provide a predetermined gap (g) with respect to the outside anastomotic member 10. The outside anastomotic member 10 is a member to which predetermined shape memory treatment is applied and can be deformed in its shape to narrow the gap (g) by reheating the outside anastomotic member 10 to predetermined temperature or above and has a C-shape wherein a part of the side surface of the member 10 is eliminated from one opening end 12 thereof to the other opening end 14 thereof.
