The invention relates to a minimally invasive intravascular stent twisting and bending fatigue simulator which comprises a liquid storage box, an electronic peristaltic pump, a pressure monitor, a current limiter and a diversion silicone tube, wherein the liquid storage box is provided with a heating device. The minimally invasive intravascular stent twisting and bending fatigue simulator is characterized by further comprising a minimally invasive intravascular stent twisting and bending simulating device. The invention also discloses a test method; according to the method, a T-shaped block horizontally moves in a sliding chute to drive a vertical hollow metal conduit to horizontally reciprocate; a gear and a rack are meshed with each other in a rolling manner to reciprocate, so as to realize the synchronous simulation of the twisting and bending motions of an intravascular stent sample in vivo; through a horizontal or L-shaped hollow metal conduit, the simulation of the intravascular stent sample at differen
