Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0024] Such as Figure 1-3 As shown, the present invention includes a catheter, a fixing assembly, an inflation device and / or a liquid filling device (not shown in the figure), the catheter passes through the 12 holes of the skull, the fixing assembly fixes the catheter to the 12 holes of the skull, and the catheter's The insertion end is provided with a balloon 2, and the non-insertion end of the catheter is connected with an inflation device and / or a liquid filling device.

[0025] When in use, the device can be implanted in a specific brain area through brain stereotaxic technology. Specifically, the two ends of the catheter are located on the outer side and the inner side of the skull 12 respectively, and the catheter is fixed to the outer ...

Abstract

The invention provides a balloon model device for simulating encephalic space occupying effect. The balloon model device comprises a catheter, a fixing component, an air charging device and / or a liquid charging device, the catheter penetrates a skull hole, the fixing component fixes the catheter to the skull hole, and an inserting end of the catheter is provided with a balloon while a non-inserting end of the same is connected with the air charging device and / or the liquid charging device. Due to adopting of the technical scheme, the catheter is fixed on the outer wall of a skull, inflation of the balloon is realized by injecting liquid to or charging air to the catheter, the balloon can be inflated to specific size and specific pressure so as to simulate encephalic space occupying effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a balloon model device for simulating the intracranial space-occupying effect. Background technique [0002] Intracranial space-occupying lesions, including tumors and hematomas, among which the stress injury caused by the space-occupying is one of the important pathological factors, that is, the damage caused by the space-occupying squeezing normal brain tissue, but there is no single factor that can control this injury The model, that is, the intracranial mass effect stress model, cannot be effectively studied. This model can be used to study the brain damage caused by different mass size, position, stress, and time of mass in acute or chronic mass. [0003] It is worth noting that hemorrhagic stroke is the cerebrovascular disease with the highest rate of death and disability. There are about 2 million new cases in my country every year, and the mortality rate is as hi...
