Description
Technical field
The utility model is related to medical instruments field, more particularly to a kind of intracranial lesion based on brain stereotactic system to wear
Thorn positioner.
Background technology
As video diagnostic technology develops so that the discovery of the small space occupying lesion of early stage encephalic becomes more and more early, and
Need the recall rate also more and more higher of the brain tumor of surgical intervention.But the operation in current clinical position for tiny intracranial focus is determined
Bit comparison is difficult, and traditional craniotomy location of operation is relatively difficult, is difficult to find lesion during surgery excision, causes operative incision big, greatly
Scope brain tissue is exposed, and other brain tissues are easily damaged when blindly detecting lesion, increases the generation of patient trauma and complication；And
For functional areas tumour, traditional micrurgy easily causes the brain tissue impairment of functional areas.And it can be cranium to use horseley-Clarke technique
Interior small lesion determines accurate locus, overcomes the problem of searching focus hardly possible in art, and design operation pathway avoids weight
Functional areas, blood vessel, tissue etc. are wanted, with reference to surgical operation microscope operation, patient may be selected optimal operative approach and excision extension, maximum
Limit mitigates additional injury of the operation to surrouding brain tissue, avoids important blood vessels and functional areas, and brain tissue impairment is minimized,
Security is improved, curative effect is improved, so as to be effectively reduced disability rate, minimally invasive, micro-invasive operation for treating hypertension is truly reached.
The pilot pin that current brain stereotactic system is used, needs to continue to place after intracranial lesion is navigated to after piercing
In encephalic, and as the factors such as the beating that dura mater brain release cerebrospinal fluid and brain tissue are opened during opening operation cranium influence, brain group
Knit and lesion locations may be shifted over, pilot pin is shifted therewith can produce obvious dissection to brain tissue, to brain group
Knit infringement very big, and pilot pin easily influences the operation under microscope, operation risk increases.It is small especially for multiple intracranial
The patient of space occupying lesion, multiple location tumour is positioned with puncture needle, such as takes out puncture needle, because brain tissue quality is softer, puncture
Duct is easily inaccessible, and brain tissue drifts about caused by the previous tumour of excision when cutting off next brain tumor, does not have positioning and makees
With；If do not taken out puncture needle, after first space occupying lesion of excision, brain tissue easily collapses displacement, the puncture localization needle of remaining focus
Surrouding brain tissue is easily cut, easily causes serious complication.
The puncture needle head end of the pilot pin of current existing other region tumors has hangnail (CN105011989A) or water chestnut
The structures such as shape (CN104490480A), can catch lump after release, but not applied to for cranium brain space occupying lesion, because encephalic is accounted for
Position lesion is different from other entity tumors such as lung neoplasm, tumor of breast, and its quality dead-soft is sharp using metals such as band hangnail, hooks
The positioning guide wire of profit, easily scratches surrounding important brain tissue and blood vessel, causes extra surgical injury.So, research and development are a kind of
Precise positioning can be solved, the positioning caused by Brain shift can be avoided to be forbidden and cutting risk again, facilitate patient more accurate
The pilot pin of removal of lesions, is always the technical problem of this area urgent need solution.
Utility model content
The purpose of this utility model is to provide a kind of intracranial lesion puncture positioning device based on brain stereotactic system,
Its technical problem to be solved is：The puncture needle that existing brain stereotactic system is used is needed after being repositioned on intracranial lesion
Continue to be positioned over encephalic, due to Brain shift, the reason such as collapse, pilot pin easily cuts the brain tissue of perilesional, also
Positioning can be caused inaccurate；And traditional pilot pin or positioning guide wire visit tartar one end and have to draw in or spring open radially release and be used for
The grasping structure of lump is caught, but this class formation is not suitable for quality dead-soft cranium brain inner tissue.
In order to solve the above technical problems, the utility model provides a kind of intracranial lesion based on brain stereotactic system puncturing
