Embodiment Construction
[0042] The present invention will be described in detail below in conjunction with the accompanying drawings. like figure 1 As shown in the structural diagram of the present invention, the system and working modes are divided into operation planning and operation simulation:
[0043] (1) Operation planning mode
[0044] Step 1: The operation planning module is initialized, and the 3D stereoscopic modeling is carried out through the CT images of real patients, such as figure 2 As shown, stones located in different calices were generated according to the actual stone position of the patient ( figure 2 Zhongwei kidneys, each kidney has 8 small calyces), stone shapes include: long strip type, concentric circle type and staghorn type;
[0045] Step 2: Import the reconstructed 3D kidney model into the 3D printer (STL file), and print out a real kidney model with the same size and shape as the real patient's kidney at a ratio of 1:1. The outer structure of the kidney is set to b...
