Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of encephalic operation positioning devices.
Background technique
Hypertensive cerebral hemorrhage (HICH) is common neurosurgical, and the death rate is high.Surgery for hypertensive intracerebral hemorrhage mode
Very much, it is determined according to situations such as position of bleeding, amount of bleeding, age, bleeding rate, time, basic diseases condition, local hospital condition
Fixed different operation method, common modus operandi have:
1, minimally invasive puncture drain and aspiration: for Intracranial puncture and drainage art treats HICH, hard channel wears again at home
Pierce drainage technology (such as YL-1 puncture needle) and soft access penetrations drainage technology.
2, big bone flap opens cranium hematoma clearance decompression: it is big for amount of bleeding, hernia cerebri patient occurs, makees on head one big
Notch, skull uplifting window remove hemotoncus decompression
3, bone window craniotomy operation evacuation of hematoma: being suitble to general quantity of hematoma, opens a small window in skull, looks at lower removing blood straight
It is swollen.
4, with the development of science and technology the utility model of various instruments and consumables associated therewith, removes hemotoncus method under minimally invasive direct-view
In various regions, development is more and more concerned, such as 3D printing technique, nerve endoscope technology, horseley-Clarke technique, Use of Neuronavigation technology, shows
The application of micro- outer technology of mind etc., keeps the treatment means of hypertensive cerebral hemorrhage more and more.
But no matter which kind of operation method, precise positioning, orientation be perform the operation it is whether successfully crucial.
Current clinically intracranial hematoma operation direction and location situation:
Localization method has (1) CT to guide lower marker positioning (2) according to CT film setting-out positioning.Above two method positioning
Afterwards, postoperative that puncture road direction is determined by space imagination according to CT film, such as from temporo side puncture point approach, then puncture direction alignment (vertical)
Hemotoncus sagittal plane, patient's ear measure direction or people's puncture, and a people, which estimates, to be guided.Merging brain-tissue passage-manufacturing device (is also named transparent hard
Matter sheath) direction, brain spatula direction of insertion, to remove hemotoncus direction be also to orient by above-mentioned thinking, and this positioning and orienting method is thick
It is rough, cause operation path to deviate normal direction sometimes, adjustment direction causes unnecessary patient until finding hemotoncus repeatedly
Brain tissue impairment brings great puzzlement to operation.
