There is provided a surgical fixing tool which can easily and reliably perform treatment such as vascular anastomosis by inhibiting an operation site on a surface of a living body such as a heart and the like from moving along a height direction of the surface of the living body in response to movements of the living body. The surgical fixing tool 1 includes a support unit 10 which exposes an area required for a living body local site and which surrounds at least a portion of the local site so as to be contacted and fixed thereto. The surgical fixing tool 1 includes a position adjusting unit 50 that is disposed in the support unit 10, and that adjusts a relative position between the support unit 10 and the fixed living body local site, for example, a local site P of a heart H, and a displacement position detection unit 80 that detects a displacement position where the local site P is displaced in a height direction (direction Z). Based on a detection result of the displacement position in the height direction (direction Z) of the local site P which is detected by the displacement position detection unit 80, the position adjusting unit 50 changes and adjusts a relative position between the support unit 10 and the fixed local site P.
