Surgical operation training device

A training device for vascular anastomotic surgery for a simulated patient, comprising:

• a case arranged to lay out a simulated body cavity of the patient with a base and a frame installed above the base to enable a trainee to access the body cavity,
• a support member extending from the base of the case;
• a holder plate extending in X-Y directions held on the support member via a biasing member extending in a Z direction, configured to hold a simulated blood vessel extending in a Y direction thereon to enable a trainee to perform anastomotic practice on this simulated blood vessel;
• first and second wire members extending from two outer sides, respectively opposing in the X direction of the holder plate, and connecting to the support member, wherein said first and second wire members support the holder plate against bias from the biasing member, and said first and second wire members are configured to contract and expand independently according to an electric current that is applied thereon;
• a controller to control a movement of the holder plate by applying the electric current to each of said first and second wire members at intervals so that the simulated blood vessel has a cyclic movement within an X-Z plane, the cyclic movement including one of or a combination of rotational, twist and linear movements, and representing pulsation movements of vascular blood vessels located in the body of the patient.
