Limiting assembly 230 is arranged on the side of bottom plate 210 away from the mounting space and is detachably connected with hoop 220, which prevents hoop 220 from coming out of mounting hole 211, thereby ensuring that the simulation tissue is fixed firmly. On the other hand, after the limiting assembly 230 is removed, the hoop 220 can be removed from the mounting hole 211, thereby facilitating the removal of the simulation tissue.

[0112] The thickness of the first elastic layer 111 is greater than that of the second elastic layer 112.

[0113] Referring to Figure 1 In the embodiment of the present application, the top wall 110 of the box assembly 100 adopts a double-layer structure comprising a first elastic layer 111 and a second elastic layer 112. The combination of the first elastic layer 111 and the second elastic layer 112 can better simulate the hierarchical feeling of the human simulated tissue. The elastic modulus of the first elastic layer 111 is greater than that of the second elastic layer 112, i.e., the first elastic layer 111 is relatively harder, while the second elastic layer 112 is relatively softer, thereby simulating different parts of the human simulated tissue. The second elastic layer 112 simulates the skin, and the first elastic layer 111 simulates the muscle. Specifically, the thickness of the first elastic layer 111 simulating the muscle is greater than that of the second elastic layer 112 simulating the skin, further increasing the authenticity of simulation and providing a more realistic simulated surgical operation experience for the user.
