Ventricular puncture model

Abstract

The invention discloses a ventricular puncture model and belongs to the field of medical teaching instruments. The ventricular puncture model is characterized by comprising a skull model, a brain model and a thrombus model; a skull is divided into an upper skull structure and a lower skull structure from the temporal part; a detachable component is arranged between the upper skull structure and the lower skull structure; holes are formed in the left and right sides of the top of the upper skull structure of the skull; a brain model comprises left and right ventricle models and a third ventricle model; the third ventricle model is arranged in the left ventricle model and the right ventricle model; the surface of the brain model is provided with grooves; venation plexus is arranged in the brain model; a specific hydrogel material is adopted, so that the touch feeling is simulated; key brain structures such as left and right ventricles and a third ventricle in an intracranial hyperbaric state are included, and important brain characteristics such as cerebral gullet, venation plexus and the like are contained; and through the design of the auxiliary fixing device and the cerebral groove position, the model can be repeatedly used for brain puncture operations such as third ventricular fistulization and cerebral hematoma aspiration, and the teaching experiment effect can be greatly improved.

Description

technical field [0001] The invention belongs to the field of medical teaching instruments, in particular to a model of ventricle puncture. Background technique [0002] Hydrocephalus and cerebral hemorrhage are common neurosurgical diseases. Hydrocephalus can be divided into congenital and acquired, and the neurological dysfunction of patients is positively correlated with the severity of hydrocephalus, so timely and appropriate treatment is very important. Early surgery can prevent or reduce the occurrence of acute hydrocephalus, reduce secondary brain damage caused by enlarged ventricles and cerebral vasospasm, and protect brain tissue from secondary damage is crucial to reducing mortality and disability. important. [0003] Ventriculocentesis is an important diagnostic and therapeutic technique in neurosurgery, and it is widely used in neurosurgery. For conventional brain puncture, a fixed puncture point is selected, and the puncture direction is guided by body surface...

AI Technical Summary

Problems solved by technology

Unskilled or inaccurate puncture operations are prone to many risks

At present, most of the existing ventriculocentesis models in the teaching field have a simplified structure inside, without the real shape of the brain parenchyma and ventricles, and are generally made of hard or other soft materials as a whole. The degree of simulation is not high, and the teaching effect needs to be further improved.
