Abstract
The invention discloses a defect repair device for a neuroendoscope through the nose. The defect repair device for the neuroendoscope through the nose comprises three circular-cake-shaped components, wherein the three circular-cake-shaped components are connected with one another and are connected to the tail end of a long catheter in sequence, the components with the corresponding diameters can be selected according to the sizes of defects, and the component on the inner layer and the component on the outer layer are communicated with the long catheter. The defect repair device for the neuroendoscope through the nose has the advantages of being simple in structure, easy to store and convenient to use.
Description
Technical field
The present invention relates to a kind of medical operation member, a kind of per nasal nerve endoscope defect repairing device particularly is can reconstruction operations damaged.
Background technology
Current neurosurgery field, per nasal nerve endoscope technology is carried out more and morely, and its Wicresoft, pair are damaged little, obtain relevant expert and unanimously approve.This technology belongs to the minimally invasive surgery field, and operation technique is meticulous and complicated, requires high.The complication of operation treatment of cerebrospinal fluid leak is still the treatment difficult point at present, once it is high that mortality rate occurs.Up to now, the means of defect repair are less, and correlation technique is all immature, restrict its development.Directly clog compressing for Postoperative reconstruction mainly with material clinically, with randomness and blindness, and have the danger such as displacement, and current cerebrospinal leak incidence rate is still high.Above shortcoming is restricting the development of nerve endoscope technology always.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, a kind of per nasal nerve endoscope defect repairing device simple in structure, easy to use is provided.
Purpose of the present invention is achieved through the following technical solutions: described patcher comprises three annulus pie structures, internal layer, intermediate mass and skin, and middle cake can be according to damaged size coupling respective model.There is a conduit in center, internal layer and layer structure respectively with it inside come round.By inject reconstruction biomaterials to ectonexine, above both expand and form and support in the damaged interior outside respectively afterwards, automatically solidify after injection to form and support.Reconstruction completes.
The present invention compared with prior art has the following advantages: the present invention supports by forming ectonexine, finally completes reconstruction, and the present invention is simple in structure, easy to use, easy and simple to handle, clinical practice large, for remote defect reconstruction practicality.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that in Fig. 1, internal layer is injected into the structural representation after reconstruction biomaterials;
Fig. 3 is internal layer and the outer structural representation all be injected into after reconstruction biomaterials in Fig. 1;
Fig. 4 is after in Fig. 1, internal layer, skin are injected into reconstruction biomaterials and removes Postductal structural representation;
Number in the figure: 1-internal layer, 2-intermediate mass, 3-skin, 4-conduit, the damaged edge of 5-.
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.
Show as shown in Figure 1 to Figure 4 a kind of embodiment of per nasal nerve endoscope defect repairing device of the present invention, comprise three round pie connected structures, being respectively that internal layer (1), intermediate mass (2) and outer (3) are unified is connected in conduit (4), and comes round with conduit (4) respectively in internal layer (1) and outer (3) inside.Reconstruction biomaterials can be injected respectively in internal layer (1) and outer (3) in its structure, makes its expansion.Above both characteristics are to increase thickness axially a small amount of, but enlarge to the periphery, cover in damaged (5) around, and fixing.Then remove structure conduit (4), form and rebuild.
The present invention is per nasal nerve endoscope defect repairing device, by ectonexine, forms and solidifies and support, and final formation rebuild.The present invention is simple in structure, and convenient in carrying is easy to use.
Claims (5)
1. a per nasal nerve endoscope defect repairing device, it is characterized in that: described patcher comprises three circular pie structures, internal layer (1), intermediate mass (2), outer (3) are drawn close together, there is certain diameter in intermediate mass, according to damaged size, be complementary, there is a conduit (4) in center, comes round with conduit (4) inside respectively in described cystic structures internal layer (1), outer (3).
2. per nasal nerve endoscope defect repairing device according to claim 1, it is characterized in that: come round with structure conduit (4) in described structure internal layer (1) and outer (3), and structure internal layer (1) can inject reconstruction biomaterials through conduit (4).
3. according to claim 1,2 described per nasal nerve endoscope defect repairing devices, it is characterized in that: described structure internal layer (1) exists while enlarging when expanding, can increase on a small quantity thickness, being mainly expansion expands laterally, finally become block shape structure, can cover damaged inner side edge surrounding on every side, put forth effort mainly to be positioned at the damaged periphery outside.
4. according to claim 1,2 described per nasal nerve endoscope defect repairing devices, it is characterized in that: described structural outside layers (3) expands while enlarging, can only increase on a small quantity thickness, being mainly expansion expands laterally, finally become block shape structure, can cover damaged outer side edges surrounding on every side, and the space certain with damaged marginal existence, put forth effort mainly to be positioned at the damaged periphery outside.
5. according to claim 1,3,4 described per nasal nerve endoscope defect repairing devices, it is characterized in that: after expanding and enlarge in described structure internal layer (1) and outer (3), can be covered in the interior outside at damaged edge (5).
