Abstract
The invention discloses a defect reconstruction instrument for an endoscopic endonasal operation of the neurosurgery development. The defect reconstruction instrument for the endoscopic endonasal operation of the neurosurgery development is of a structure which comprises two round-cake-shaped bag-shaped hollow clamping pieces, the middles of the two clamping pieces are connected with a long catheter, and a curled structure is arranged at the periphery of the bag-shaped structure, and can extend towards the outer side. The defect reconstruction instrument for the endoscopic endonasal operation of the neurosurgery development has the advantages of being simple in structure, easy to store, and convenient to carry and use.
Description
Technical field
The present invention relates to a kind of medical equipment, particularly a kind of neurosurgery scope is through the reconstruction apparatus of nasal operation.
Background technology
At present, the nerve endoscope technology is carried out more and morely, and the postoperative defect of skull that exists in the operation of endoscopic technic, can cause the postoperative complications cerebrospinal leak, once occur, mortality rate is high, be a difficult problem and rebuild always, must address this problem, could carry out better related surgical.Before general method for reconstructing give exactly corresponding reconstruction biomaterials directly filling and glue fix, effect is not good enough, and randomness is larger; Also can rebuild step by step, but the situations such as easy displacement occur.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, provide a kind of neurosurgery simple in structure, easy to use to rebuild apparatus.
Purpose of the present invention is achieved through the following technical solutions: a kind of reconstruction apparatus of intranasal videoendoscopic surgery, be included as clamping piece structure empty in two cryptomeres with round pie, both are connected with long duct respectively at middle part, and there is coiled structure in the cystic structures periphery, can expand laterally.
The present invention compared with prior art has the following advantages: the present invention is that an easy nerve endoscope is rebuild apparatus, and the present invention is simple in structure, easy to use.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 injects the structural representation after reconstruction biomaterials (A) to the structure internal layer;
Fig. 3 is to structure internal layer and the outer structural representation injected after reconstruction biomaterials (B);
Fig. 4 is for removing Postductal structural representation;
Number in the figure: 1-internal layer, 2-skin, 3-conduit.
the specific embodiment:
in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, Figure 2, Fig. 3 and Fig. 4 show a kind of embodiment that nerve endoscope of the present invention is rebuild apparatus, comprise two connected internal layers 1 and outer 2 side by side, both come round respectively with conduit 3 in the middle of being connected, internal layer 1 and the outer 2 inner passages of coming round to offside that exist.Rebuild material (A and B) by internal layer 1 and outer 2, injecting respectively two kinds, once these two kinds of materials are in contact with one another, form solid, support and rebuild.During operation, only need to be placed in the interior outside that needs preparing structure to ectonexine, distinguish inwardly outside injected material simultaneously, once meet, finally realize reconstruction.
The present invention is that an easy nerve endoscope is rebuild apparatus, by injecting in the cavity capsule, rebuilds material, forms supporting layer, and final the realization rebuild.Clinical easy to use, practical, the present invention is simple in structure, easy to store, and convenient in carrying is easy to use.
