In surgical procedure, deformation pipe sleeve access opening footpath becomes big, and tube wall is expanded outwardly, and the via hole on the outside of tube wall is with tube wall
Stretcher strain and become big so that the extraneous water and air of deformation pipe sleeve is entered in inner chamber by via hole.In tube wall inner chamber
Solidify liquid solidifies with water or air contact so that deformation pipe sleeve is fixed on certain form, so as to reach the purpose of compressing nasal cavity.
It is preferred that, have in inner chamber along tube wall circumferentially around annular chamber, resist radial load.
It is preferred that, position of the via hole on the outside of tube wall is corresponding with the position of annular chamber, when deformation pipe sleeve passage expansion,
After via hole aperture becomes big, extraneous water and air energy is preferably and the solidify liquid inside annular chamber preferably contacts solidification.
It is preferred that, have in inner chamber along the axially extending axial cavity of tube wall, the anti-folding of bending resistance.
It is preferred that, position of the through hole on the outside of tube wall is corresponding with the position of axial cavity, when deformation pipe sleeve passage expansion, leads
After through-hole aperture becomes big, extraneous water and air energy is preferably and the solidify liquid inside annular chamber preferably contacts solidification.
It is preferred that, the annular chamber in inner chamber is connected with axial cavity, can reduce hardening time, improves resistance to deformation intensity.
It is preferred that, the solidify liquid of interior intracavitary filling is α-cyanoacrylate, α-cyanoacrylate meet water or
Humid air is catalyzed, and solidification can be adhered rapidly, be reached more preferable solidification effect.
It is preferred that, deformation pipe sleeve is divided into front end and end, and front end and end two ends bore differ, and front end bore is end port
The 3/4 of footpath.Beloid deformation pipe sleeve facilitates front end to enter nasal cavity, is easy to operation.
It is preferred that, the outer surface of deformation tube casing wall is provided with hemostasis coating, and hemostasis coating is mainly used in blood vessel in mucous membrane and received
Contracting accelerates blood clotting.
It is preferred that, contain adrenaline in hemostasis coating, adrenaline can stimulate blood vessel so that vessel retraction, reaches only
The purpose of blood.
Compared with prior art, the curable deformation tube for intranasal endoscopic surgery of above-mentioned technical proposal is employed
Set, has the advantages that：
Using the curable deformation pipe sleeve for intranasal endoscopic surgery of the present invention, with the passage in deformation pipe sleeve
Expansion, during tube wall expands laterally, water and air is contacted with solidify liquid, and solidify liquid curing rate is fast, required time
It is short.
Meanwhile, in surgical procedure, air bag or enlarging pincers etc. are penetrated in the middle part of deformation pipe sleeve, the internal channel for deforming pipe sleeve is supportted
Greatly, the tube wall of deformation pipe sleeve is allow to fit nasal cavity inwall, after after the solidify liquid solidification of interior intracavitary, solidify liquid is formed in the lumen
The skeleton that one shape is fixed, for the structure and shape of supporting deformation pipe sleeve, due to the solidify liquid in inner chamber after hardening not
Can deformation, can be fitted with nasal cavity inwall with complete stability, will not occur break-off in operation, scope and operation apparatus can be with
More easily pass through so that surgical procedure is more reliable and stable.

Embodiment
The present invention is described further below in conjunction with the accompanying drawings.
The curable deformation pipe sleeve for intranasal endoscopic surgery as shown in Figures 1 to 4, including deformable tube wall 1
And for nerve endoscope or the passage for operating apparatus to pass through.
Tube wall 1, which has, fills this solidify liquid in a hollow inner chamber 2, inner chamber 2, solidify liquid with after water or air contact itself
Can solidifying and setting.
The outside of tube wall 1 is additionally provided with via hole 3, while expansion in passage aperture, and deformation tube casing wall 1 is swollen to outside
It is swollen so that the aperture of via hole 3 also becomes big therewith, advantageously passes through in water or air.
The inner chamber 2 in via hole 3 and tube wall 1 on tube wall is interconnected, can first by the water or air of via hole 3
Time contacts with the solidify liquid in inner chamber 2, solidifies solidify liquid.
In surgical procedure, deformation pipe sleeve access opening footpath becomes big, and tube wall 1 is expanded outwardly, and the via hole 3 in the outside of tube wall 1 becomes big,
So that the extraneous water and air of deformation pipe sleeve is entered in inner chamber 2 by via hole 3.Solidify liquid and water or air in inner chamber 2
Contact solidification so that deformation pipe sleeve is fixed on certain form, so as to reach the purpose of compressing nasal cavity.
Inner chamber 2 in tube wall can be along tube wall 1 circumferentially around annular chamber 21, annular chamber 21 is distributed in pipe with proportional spacing
In wall 1, radial load is resisted.Solidify liquid solidification can make deformation tube set sizing in actual operation, it is ensured that solidify in surgical procedure
Alteration of form does not occur for deformation pipe sleeve afterwards.
Inner chamber 2 in tube wall can also be that axial cavity 22 is distributed with proportional spacing along the axially extending axial cavity 22 of tube wall 1
In tube wall 1, the anti-folding of bending resistance.Ensure that alteration of form does not occur for deformation pipe sleeve after solidify liquid solidification in same axial cavity 22.
Via hole 3 is corresponding with the position of annular chamber 21 or axial cavity 22 in the position in the outside of tube wall 1, when deformation pipe sleeve leads to
Road is expanded, after the aperture of via hole 3 becomes big, and extraneous water and air can consolidating preferably and inside annular chamber 21 or axial cavity 22
Change liquid and preferably contact solidification.
In the present embodiment, inner chamber 2 include along tube wall 1 circumferentially around annular chamber 21 and axially extending along tube wall 1
Axial cavity 22, and annular chamber 21 and axial cavity 22 are interconnected, and such cavity body structure can better ensure that deformation pipe sleeve
The stability of shape after hardening.
The solidify liquid filled in inner chamber 2 is α-cyanoacrylate.α-cyanoacrylate meets water or moist empty
Gas is catalyzed, meeting solidification adhesion rapidly, is solidification in the curable deformation pipe sleeve of the invention for intranasal endoscopic surgery
The preferable material of liquid.
Pipe sleeve is deformed in the present invention and is divided into front end and end, front end and end two ends bore differ, front end bore is end
The 3/4 of bore.Beloid deformation pipe sleeve facilitates front end to enter nasal cavity, is easy to operation.
The outer surface of deformation tube casing wall 1 is mainly used in mucous membrane vessel retraction or added provided with hemostasis coating, hemostasis coating
Fast blood clotting.
Contain adrenaline in hemostasis coating, adrenaline can stimulate blood vessel so that vessel retraction, reaches the mesh of hemostasis
's.
It is described above to make the preferred embodiment of the present invention, this hair is not departed from for the person of ordinary skill of the art
On the premise of bright principle, some variations and modifications can also be made, these also should be regarded as protection scope of the present invention.
