Embodiment 1
[0039] See attached figure 1 , a temporal bone model for surgical training, mainly used for temporal bone-related surgical training, which includes cancellous bone 1 and cortical bone 2 from inside to outside.
[0040] Among them, cancellous bone 1 has a porous structure and contains three raw materials: mixed powder, water and graphite powder; the mixed powder is uniformly mixed with 85% clay and 15% feldspar powder by weight, and the mixed powder, water and The weight ratio of the graphite powder is 8:2:1; the graphite powder mainly acts as a pore-forming agent in the cancellous bone 1 and can assist the cancellous bone 1 to form a porous structure during the sintering process.
[0041]The cortical bone 2 contains two raw materials of mixed powder and water, and the mixed powder has the same ingredients as the mixed powder used for the cancellous bone 1 above; in the cortical bone 2, the weight ratio of the mixed powder to water is 8:2.
[0042] Cancellous bone 1 and cortic...
Embodiment 2
[0046] See attached Figure 1-2 , a molding method for manufacturing the above-mentioned temporal bone model, comprising the following steps:
[0047] S1. Using CT to obtain multiple cross-sectional scan images of the temporal bone structure of the human body, and respectively reconstruct the multiple cross-sectional scan images to obtain multiple corresponding reconstructed cross-sectional images, and establish the temporal bone structure based on the multiple reconstructed cross-sectional images 3D geometric model.
[0048] In order to ensure that the anatomical structure of the constructed temporal bone model is consistent with the researched living anatomical structure, it is necessary to obtain multiple cross-sectional scanning images of the temporal bone structure based on the patient's individualized medical images when constructing the temporal bone structure model, and the patient's individualized medical images The acquisition methods include, but are not limited to...
