Description
Technical field
The invention belongs to the medical instruments technical field, particularly relate to and a kind ofly be used for that neural navigating surgery can accurately be located and the medical apparatus of labelling brain DEEP STRUCTURE and pathological tissues.
Background technology
At present; Be not specifically designed to neural navigating surgery (taking out) as yet and focus positioned the sting device of labelling like excision of intracranial tumor, the pathological changes biopsy of intracranial deep, functional neurosurgery surgical operation, intracranial foreign body; The navigation rod of assist location does not possess the function of labelling in the art; The brain puncture needle can not navigate registration, can't under navigation guide, puncture, and the puncture needle needle track not possess scale mark, range measurement inconvenient.In order under navigation guide, to seek the cerebral tumor or small lesion, tumor boundaries and operation pathway, often can only excise situation through the position and the pathological changes that arrive in the repeatable operation navigation rod feedback art in the art, the operation process is slow, damages bigger.And; In the neural navigating surgery owing to the cerebrospinal fluid outflow, use dehydrant, tractive cerebral tissue, open behind the cranium cerebral tissue and changed by gravity and holding power or the tumor of larger volume is excised; All will cause brain inner structure relative position to change; Make it and art before produce deviation between the image, be the image drifting problem.The image drifting problem has had a strong impact on the accuracy of real-time navigation in the operation, becomes the greatest drawback of neural airmanship, has increased great work difficulty to the medical worker.
Summary of the invention
For more convenient, neural navigating surgery telltale mark accurately is provided, reduce the navigation operation step, avoid the image drift to cause locating inaccurate defective, the invention provides a kind of neural navigator fix labelling apparatus.This device can carry out the multiple spot micro-mark, to target area or a small amount of green of path tag or blue non-toxic dye, makes that target is clear reflects, and gauge point or path label do not receive factor affecting such as cerebrospinal fluid outflow, thereby has avoided the problem of image drift.This device design is ingenious, simple to operate, can guide operation accurately, reduces the wound to normal cerebral tissue, helps finding lesion region rapidly and it being excised fully, drops to the incidence rate of post-operative complication minimum.
Neural navigating surgery telltale mark device according to the invention; Comprise epitheca puncture needle body 2 and nook closing member 6; Said epitheca puncture needle body 2 is provided with at least one side opening 3, and the epitheca puncture body is in 4 sealings of epitheca head end, and said nook closing member 6 is provided with nook closing member opening 5 for hollow and at head end; The internal diameter of the external diameter of said nook closing member 6 and said epitheca puncture body acupuncture 2 matches, and nook closing member 6 places in the epitheca puncture needle body 2 slidably.
The technical scheme that the present invention solves its technical problem employing is: the brain that designs a kind of improvement is threaded a needle, and is made up of with nook closing member 6 epitheca puncture needle body 2, and wherein epitheca tail end 1 is thicker, and is convenient hand-held, and can bind the navigation coordinate appearance, and needle body is provided with side opening 3 backward from head end.Nook closing member hollow, and be provided with nook closing member opening 7 at head end, tail end is provided with nook closing member needle handle 5, can connect syringe.Nook closing member indicates scale along major axis, and through matching, nook closing member 6 can slide in epitheca, can make the side opening complete closed of epitheca when inserting fully in nook closing member 6 external diameters and the epitheca, can make the side opening of epitheca head end respective number open after part withdraws from.
Among the present invention, the number of the side opening 3 that on epitheca puncture needle body 2, is provided with is at least 1, is preferably 11, and wherein first side opening 3 is located at the epitheca head end 4 about 1-3mm places apart from epitheca puncture needle body 2, is preferably the 2mm place; Distance between each side opening is 8-10mm, preferred 10mm.The aperture of side opening can be established size and is the aperture of 1-3mm, the more preferably aperture of 2mm; The internal diameter size of the epitheca puncture needle body 2 that matches with nook closing member 6 external diameters can be 1.8-2.5mm, is preferably the internal diameter size of 2.2mm.
Among the present invention, the other end of said epitheca puncture needle body 2 also be provided with a thickness degree puncture needle body thicker for hand-held epitheca afterbody 1, the size of epitheca afterbody 1 can be external diameter 8-12mm, preferred 10mm, long 40-50mm, preferably 45mm; Thickness is 3-5mm, is preferably 4mm.
At the epitheca afterbody, can bind the navigation coordinate appearance, so that when operation, position the labelling navigation, accomplish localised puncture.
Among the present invention, nook closing member 6 is provided with scale, and graduated original position is located at nook closing member opening 7 places; Unit is mm, and external diameter can be the 1.8-2.5mm size in the nook closing member, and external diameter is preferably 2.1mm; Internal diameter is preferably 2.0mm, and nook closing member length can be 100-200mm, is preferably 150mm.
The invention has the beneficial effects as follows that this invention is simple to operate, easy to use, precision is high, be based on the preceding image check of art, accuracy is high; Do not receive brain displacement in the art, the influence of image drift to navigating in the art; Shortened the time of using navigator, efficient is higher, helps improving operation safety.Can make that neural navigating surgery target is clearer and more definite, damage is littler, be the useful additional apparatus of neural navigation, and high clinical use value and economic results in society are arranged.
