Abstract

The invention relates to an auxiliary marking tool for surgical operation and a marking method, the tool comprises a main body, and the main body comprises a line drawing contour matched with a designed suture track. Before the line is drawn, the main body is attached to the valve suturing position, the outline of the drawn line coincides with the designed suturing track, then the line is drawn at the valve suturing position along the outline of the drawn line to form the mark, and during subsequent suturing, the valve or the patch is sutured along the mark. The auxiliary marking tool assists in line drawing and marking, the suturing track can be accurately marked, and it is guaranteed that the position of a valve or a patch after suturing is accurate.
