Simulated brain model and preparation method thereof

Abstract

The invention discloses a simulated brain model and a preparation method thereof. The simulated brain model comprises a brain model body containing tractable brain tissue and a tumor simulating devicearranged inside the brain model body, wherein the tumor simulating device is in contact with the tractable brain tissue, and comprises a main body made of a soft material with a cavity, an opening formed in the surface of the main body and a stopper for blocking the opening. According to the simulated brain model, the elasticity and the touch feeling of real brain tissue are simulated to the greatest extent; the tumor simulating device is positioned in the brain model body and inflated and formed, so that the state that a real tumor strongly braces and extrudes the brain tissue is simulated to achieve the simulation effect; the tumor simulating device can be in any shape, variety, size and position, and is flexible and convenient; and after being used in a simulating tumor resection operation, the simulated brain model can be used for establishing tumor simulants of other parts or of different sizes and shapes, and the brain model containing a plurality of tumor simulating devices canalso be prepared to achieve the effect of flexible and recyclable use.

Description

technical field [0001] The invention relates to the technical field of clinical medicine, in particular to a simulated brain model and a preparation method thereof. Background technique [0002] With the development of neurosurgical equipment and technology, a large number of intracranial diseases can be solved by craniocerebral surgery. The cadaveric head model can provide preoperative practice conditions for craniocerebral surgery. However, the structure and position of the cranial brain will change after the cadaveric head is preserved. Increasingly, most neurosurgeons currently train surgically through computer simulations and autopsies. However, many craniocerebral diseases are specific, and the corresponding surgical or teaching models or cadavers are almost difficult to express realistically. In recent years, with the development of 3D printing technology, some human tissues and organs can be 3D printed and shaped, which has become an important method to assist doct...

AI Technical Summary

Problems solved by technology

However, due to the limitations of the materials that can be used for 3D printing, the quality of human tissue and organ models such as cortical brain tissue directly obtained by 3D printing is poor, and its performance is far from the real structure and texture of the human body, and is Can not meet the clinical use needs

Especially for brain models containing tumor-simulating devices, existing brain models cannot well simulate the state of tumors compressing surrounding tissues

Prior art CN108847111A discloses a cranial brain simulation model and its preparation method, which can prepare a cranial brain simulation model with softness, elasticity and touch, but for tumors and other lesion tissues, it is also obtained through 3D printing, which cannot Solve the problem of simulating the state of the tumor compressing the surrounding tissue
