Description
Technical field
The utility model relates to neurosurgery the field of medical instrument technology, more particularly to a kind of skull bone window end hole
Device.
Background technique
In neurosurgery operation of opening cranium, bone window formation is very important step, then suspends periphery endocranium in midair attached
Nearly muscle/fascia/use abrasive drilling on the cavity that bone edge is formed, avoids endocranium from removing to form hemotoncus with this, reduces operation risk.
But muscle/fascia receiving dynamics is poor, and influences cranial bone flap recovery fixation when the cranium of pass, easy avulsion, which causes to suspend in midair, to fail；And
It is punched in bone edge for suspending endocranium in midair with abrasive drilling, not only needs more people's auxiliary operations, and time-consuming, laborious, be easy to damage brain tissue,
Also costly, also only large-scale neurosurgery hospital just carries out purchase abrasive drilling expense both at home and abroad at present.Therefore, for a long time, such as
What is convenient and efficient and time saving, laborsaving do not damaged again while the punching of bone edge brain tissue be always clinical neurosurgery urgently
Technical problem to be solved.
Existing bone window end hole is usually that the more people of neurosurgeon cooperate completion, and a people is punched using abrasive drilling, and one
People prevents from boring using gasket hurts brain tissue, and a people, which pushes Surrounding muscles scalp open and reduces, to be hindered, and time-consuming is also grown.
In existing operation of opening cranium, the individual fixed protection of skull bone edge drilling can be arranged in order to protect brain tissue in doctor
Device, for example Chinese Patent No. 96206635.4 disclose a kind of protection device, fixed encephalic protector skull perforation.But
Although the device being separately provided can play a protective role, still needing to abrasive drilling (generally only can just have in biggish neurosurgery
Instrument) etc. instrument costly be used cooperatively, need both hands to operate, it is still relatively time-consuming.
Therefore, existing skull bone window end hole technology has yet to be improved and developed.
