Endocranium fret saw for preventing acute encephalocele in craniocerebral trauma operation

Abstract

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.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a dura mater wire saw used for preventing acute encephalocele in craniocerebral trauma operation. Background technique [0002] For patients with craniocerebral trauma, when the intracranial pressure is high, the patient must be in a brain herniation or is about to have a brain herniation, and only a large bone flap decompression can be successfully treated. To decompress the large bone flap, it is necessary to cut the dura mater extensively. Only when the dura mater is completely opened can the decompression be achieved. However, due to the extremely high pressure in the brain of some patients, once the dura mater is cut, acute encephalocele will occur. Bulging, the mortality rate of patients is almost 100%. At this time, the bone window has been made, and the dura mater is as hard as a stone. If the dura mater is cut a small incision, the brain tissue will squeeze out. The hernia could...
