PROBLEM TO BE SOLVED: To provide an assembled surgical instrument for tricuspid regurgitation capable of easily treating tricuspid regurgitation by moving through the inferior vena cava-tricuspid valve-pulmonary artery. An assembled tricuspid valve regurgitation surgical instrument of the present invention includes a pulmonary artery fixing member installed in a pulmonary artery, and a connecting tube having a connecting tube lumen formed therein so as to be movable along a connecting wire. An assembly unit that includes a first assembly that is coupled to a lower end of the pulmonary artery fixing member and a second assembly that is coupled to an upper end of the connecting tube so that the pulmonary artery fixing member and the connecting tube are assembled. , A lower vena cava fixing member connected to the lower end of the connecting tube and installed in the inferior vena cava, and connected to one side of the connecting tube to obliquely penetrate the tricuspid valve to block the tricuspid valve orifice. And a blocking unit.
