Problems solved by technology

However, due to the limited sources of human cadavers and increasingly expensive prices, factors such as religion, culture and related regulations have also increased the difficulty of promoting the training of temporal bone anatomy in cadavers
Considering the above factors, in recent years, researchers have begun to explore alternative models that can be used in otology teaching and surgical skills training; however, due to the limited degree of simulation of the models, it is difficult not only to present the anatomical structure more accurately, but also to simulate the real Drilling touch greatly affects the training effect of temporal bone-related ear surgery skills

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...

Abstract

The invention discloses a temporal bone model for surgery training and a forming method thereof, which belong to the technical field of ear surgery training aids. The temporal bone model for surgery training comprises a cortical bone, a cancellous bone, a semicircular canal, an ear bone and a face neural tube, wherein the cancellous bone is of a porous structure; the semicircular canal and the face neural tube are of cavity structures; the ear bone is of a solid structure; the semicircular canal, the ear bone and the face neural tube are integrally formed by adopting aluminum oxide ceramics through 3D (Three-dimensional) printing; the cancellous bone is prepared from three raw materials: mixed powder, water and graphite powder; the mixed powder is prepared from mixing 85 percent by weightof clay and 15 percent by weight of feldspar powder; the cortical bone is prepared from two raw materials: mixed powder and water. The invention provides the temporal bone model for surgery training and the forming method thereof. The temporal bone model for surgery training is higher in biofidelity, lower in manufacturing cost, and capable of greatly improving a surgery training effect, shortening a doctor training period, reducing doctor training cost, and benefitting patients.

Description

technical field [0001] The invention relates to a temporal bone model for surgical training and a forming method thereof, and belongs to the technical field of ear surgery teaching aids. Background technique [0002] The temporal bone is the most delicate and complex bone in the human body. It contains important frontal nerves, blood vessels, and auditory structures. A little carelessness in surgery can lead to serious complications. Ear surgery related to the temporal bone requires doctors to have a comprehensive and thorough understanding of the anatomy of the temporal bone, as well as rich experience and surgical skills to avoid damage to the facial nerve, internal carotid artery, cochlea and other fine structures during the operation. [0003] For a long time, generations of otologists have been cultivated by repeatedly dissecting the temporal bones of human cadavers to obtain and improve relevant surgical skills. However, due to the limited sources of human cadavers, t...
