Heart-surgery simulated training system

The invention relates to a heart-surgery simulated training system, comprising a top cover, an operation box and a chassis, wherein a curved hole is formed in the middle part of the top cover and consists of four edges of which three are straight edges and one is convex curve; the two sides of the curved hole are provided with sliding grooves which are provided with arc-shaped sliding covers; bolts for adjustment under the two ends of the arc-shaped sliding covers are respectively arranged in the two sliding grooves; the edges of the arc-shaped sliding covers, which are opposite to the convex curve, are concave; the concave parts of the arc-shaped sliding covers are matched with the convex curve; the two side walls of the operation box are provided with adjusting grooves; the two adjustable supporting plates are hinged mutually, and the other ends of the two adjustable supporting plates are respectively provided with an adjusting handle; the adjusting handles are clamped in the adjusting grooves on the two side walls of the operation box; the two adjustable supporting plates form a V shape; and a heart specimen is placed in the V-shaped concave parts of the two adjustable supporting plates. The heart-surgery simulated training system has the advantages that the practical state in the heart surgery can be simulated, so that better conditions are provided for practical training of the heart surgery.
