Description

Brain glioma pathological tissue tumour core extraction element

Technical Field

The invention relates to a tumor core extraction technology, in particular to a device for extracting a tumor core of a brain glioma pathological tissue.

Background

Brain gliomas (gliomas) account for approximately 46% of intracranial tumors. The incidence rate of glioma in brain tumor is the highest, and the peak of the comprehensive incidence age is 30-40 years old, or 10-20 years old. Gliomas occurring in the hemisphere account for about 51.4% of all gliomas, with astrocytomas being the most abundant, and then gliomas and oligodendrogliomas, and the ventricular system is also the site where gliomas occur more, accounting for 23.9% of the total gliomas, mainly ductal, medulloblastomas, astrocytomas, and cerebellar gliomas accounting for 13% of the total gliomas, mainly astrocytomas. Brain stem glioma is the collective term for gliomas occurring in the pontine, midbrain and medulla oblongata. The age of onset is statistically divided into two peaks, the first peak is 5-10 years old, and the second peak is 40-50 years old, so that the disease can be classified into children type and adults type. The tumor of the central nervous system of children accounts for 10% -20% of the tumor of the central nervous system of children, and accounts for 30% of the tumor of the posterior cranial fossa of children.

Brain gliomas are the most common primary craniocerebral tumors arising from brain and spinal glioblastomas canceration. Like other tumors, gliomas are also caused by the interplay of innate genetic high risk factors and environmental carcinogens. In the pathological research of brain glioma, the extraction of pathological tissues of tumor is an important and significant work. In medical research, when the boundary between glioma cell and normal brain tissue is known, pathological tissues of four parts, namely normal brain tissue (a part inevitably cut off during surgery), edema zone, glioma zone, tumor core and the like, are usually cut out in the surgical approach for removing tumor.

In the operation of tumour disease excision, the tumour core generally extracts through ordinary medical tweezers, when extracting the tumour core with ordinary tweezers, the stress point of tumour core only is two and the lifting surface area is little, and current extraction element is when extracting the tumour core, fixed mode to the tumour core is single, clamping stability is not good, take place to drop easily at the in-process tumour core that draws, need carry out the secondary and draw, medical personnel's work load has been improved, increased the tumour core simultaneously and extracted required time, patient's treatment experience has been reduced.
