Abstract

A device for surgical training comprising: an external first layer (11, 45) which simulates the subcutaneous fat; a second layer (12, 44) internal to said first layer (11, 45), which simulates the muscle; a fourth layer (16, 17, 42), internal to said second layer (12, 44), which simulates the perirenal fat; a kidney (14, 15, 41), internal to said fourth layer (16, 17, 42); said first, second and fourth layer having a sound propagation velocity between 1500 and 1550 m/s, an acoustic impedance between 1.5 and 1.7 106 Kg/sm2, an elastic modulus between 0.4 and 4.2 kPa, and being able to be perforated manually by surgical instruments.
