PROBLEM TO BE SOLVED: To provide a simulated organ suitable for surgery practice simulating a surgical operation in the vicinity of a simulated blood vessel using the simulated substance.SOLUTION: The simulated organ comprises a simulated blood vessel which simulates a human blood vessel being embedded in the simulated substance which simulates a human parenchymal cell. The simulated substance has a pin-push breaking strength of 0.01 to 0.07 MPa per unit area. The simulated blood vessel has a tensile break strength of 0.3 to 1.5 MPa.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】模擬血管周辺での模擬実質の切開や切開を想定した手術練習に適した模擬臓器を提供する。【解決手段】模擬臓器は、人体の血管を模した模擬血管を、人体の実質細胞を模した模擬実質に埋設して備え、模擬実質は、0.01~0.07MPaの単位面積当たりのピン押し破断強度を備える。また、模擬血管は、0.3~1.5MPaの引張破断強度を備える。【選択図】図3
