The invention relates to an
endocranium fret saw for preventing acute encephalocele in a
craniocerebral trauma operation. The
endocranium fret saw comprises a casing
pipe and a fret saw body, a line is marked on the inner side of the casing
pipe, an opening is formed in the inner side of the middle of the casing
pipe, and the fret saw body penetrates through the casing pipe. The
endocranium fret saw has the advantages that the fret saw body is arranged, the endocranium is
cut open by the fret saw body after the cranium is closed,
brain tissue plumped backwards after the endocranium is
cut open is blocked by sutured muscular
layers and the
scalp, the outside of the
scalp can be bound by bandages, so that the intracranial and extracranial
pressure difference is controlled, intracranial hypertension is released step by step, the
brain tissue is prevented from being bulged outwards rapidly, and acute encephalocele is greatly avoided. After the cranium is closed, under the non-visual condition, the fret saw is used for
cutting the endocranium open, the casing pipe separates the fret saw body from the
brain tissue, and the brain tissue can be prevented from being hurt.
