Embodiment Construction

[0016] The three time points during the operation when intracranial pressure decreased were bone flap removal, dura mater incision, and debridement of intracranial hematoma and brain contusion. After the bone flap was removed, the intracranial pressure dropped suddenly due to the compliance of the dura mater. This step cannot be directly intervened, but the dura mater can be cut slowly for 2-3 minutes to allow the cerebral blood vessels to adapt slightly, and use this short period of time to complete the suspension of the main part of the dura mater. At the second and third time points. "Limited Gradual Decompression" works well. "Limited decompression", that is, limited decompression within a controllable range; "gradual decompression", that is, gradual decompression in stages, using multi-point scattered small incisions to explore the dura mater to remove hematoma and brain contusion. This is the initial limited decompression, and then the subdural space is expanded by spe...

Abstract

The invention provides a limited and gradual decompression control system for acute cerebral hemispheric swelling. A method for the limited and gradual decompression control system comprises 'limited decompression' and 'gradual decompression', the 'limited decompression' includes decompression within a controllable range in a limited manner, the 'gradual decompression' includes gradual decompression at different steps, the cerebral dura mater of a patient is incised off to remove hematoma and contusion and laceration of the brain of the patient via multiple small scattered incisions, so that primary limited decompression is completed, and then a subdural space of the patient is expanded by a special cerebral dura mater incision tension-reduced repair method to complete decompression once again. In a surgery process, the cerebral dura mater covers swollen brain tissues and are not completely opened all along, and sudden 'pressure loss' can be avoided. Incarceration of brain tissues and surface blood vessels can be avoided by means of releasing a dura mater ring. In addition, a common method for releasing skin under galea aponeurotica in the orthopedics is used in a brain swelling surgery, recompression of scalp to the brain tissues can be avoided, a decompression effect is guaranteed, and death caused by acute cerebral hemispheric swelling is avoided.

Description

technical field [0001] The invention relates to a brain tumor operation control system, in particular to a limited gradual decompression control system for acute cerebral hemisphere swelling. Background technique [0002] Acute posttraumatic cerebral hemispheric swelling (Posttrau-PACHS) is prone to acute swelling encephalocele during craniotomy and decompressive craniectomy, with high surgical risk and high mortality. [0003] The mechanism of acute swelling encephalocele during PACHS operation is that the intracranial vasomotor center is damaged due to trauma, brain swelling is caused by acute expansion and congestion after cerebral vascular paralysis, and the sudden craniotomy and decompression in the state of high intracranial pressure make the cerebrovascular passive. Sexual expansion, brain tissue congestion and swelling intensified, continued to bulge out of the bone window, blood vessels on the surface of the brain were incarcerated at the edge of the bone window, an...
