3D printing cerebral hemorrhage model for puncture training and efficient manufacturing method thereof

Abstract

According to the 3D printing cerebral hemorrhage model for puncture training and the efficient manufacturing method of the 3D printing cerebral hemorrhage model, the smooth interface of an upper skull and a lower skull is limited and combined through a limiting groove and a limiting boss to form the whole simulation skull, a flexible simulated hematoma block is installed in the lower skull through a skull seat, and the simulation skull is further filled with a flexible simulated brain tissue; the simulated brain tissue wraps the simulated hematoma block, and the simulated brain tissue and the simulated hematoma block are made of transparent materials; after a 3D model is created by imitating any real cerebral hemorrhage case clinically, an individualized model is manufactured through a 3D printing technology and is used for practical puncture operation training; pathophysiological changes of cerebral hemorrhage can be completely simulated, and puncture experience of the model is vivid; after the operation is completed, the path deformation of the puncture needle can be visually inspected through the transparent simulated brain tissue and the simulated hematoma block, and the puncture effect can be clearly judged; and the device is accurate in position, can be repeatedly used or recycled, and is simple in structure, low in cost and convenient to operate.

Description

technical field

[0001] The invention belongs to surgical technique training in the technical field of medical teaching, and in particular relates to a 3D printed cerebral hemorrhage model for puncture training and an efficient manufacturing method thereof. Background technique

[0002] Cerebral hemorrhage is a bleeding disorder caused by rupture of blood vessels in the brain parenchyma caused by various etiologies. Its early mortality rate is very high. Most of the survivors have complications and sequelae of varying degrees. Minimally invasive puncture and drainage are used to treat intracranial hematoma. The method is developing rapidly and has the advantages of less trauma, less sequelae and complications, but its surgical effect still depends on the skill level of the operator, and the technical level of the operator needs to be improved through the accumulation of practical experience. The cerebral hemorrhage model in the prior art The production methods are generally d...
