A surgical fixing tool for vascular anastomosis inhibits an operation site on a surface of a living body such as a heart from moving along a height direction of the surface of the living body. The fixing tool has a position adjusting unit disposed in a support unit 10 that adjusts a relative position between the support unit and the fixed living body local site. A displacement position detection unit detects a displacement position of a local site. Based on a detected displacement, the position adjusting unit changes and adjusts a relative position between the support unit and the fixed local site.
