Middle sleeve 31 is cased with inside outer tube 22, middle sleeve 31 stretches out by rear end part inside the rear end circular hole of ejector sleeve 21, promotes ejector sleeve
21, ejector sleeve 21 can drive outer tube 22 to be axially slid relative along middle sleeve 31, before the first half outer tube wall of middle sleeve 31
End part is evenly distributed with three groups or more than three groups spiral sacculus 12, and spiral sacculus 12 is from the front position spiral winding of middle sleeve 31
To the centre position of middle sleeve 31, the side wall of spiral sacculus 12 is folded form, the tube wall of middle sleeve 31 corresponding to each spiral sacculus 12
On be provided with multiple passages, passage follows spiral sacculus 12 to be arranged in the stationary plane uniform spiral of middle sleeve 31, when being filled with
During gas, spiral sacculus 12 can quickly fill expansion, and now the section of spiral sacculus 12 is sector, after gas drains, spiral
It is in folded form that sacculus 12, which shrinks, and folding position is located at the side wall of spiral sacculus 12, and the front and back end of spiral sacculus 12 is with smooth
The gradient is contracted on the tube wall of middle sleeve 31, fixed on the outer wall for the middle sleeve 31 that the end of the front and back end of spiral sacculus 12 is first and end is last
Marking ring 15 is cased with, the main function of Marking ring 15 is to mark spiral 12 particular location in vivo of sacculus, inside middle sleeve 31
Inner sleeve 11 is cased with, the middle sleeve 31 in the corresponding region of spiral sacculus 12 is internally provided with and 12 the same number of spiral shell of spiral sacculus
Circumflex branch stay 13, spiral support bar 13 are fixed between middle sleeve 31 and inner sleeve 11, and each spiral support bar 13 is arranged at
Interstitial site of two neighboring spiral sacculus 12, the outer tube wall of the front end face and inner sleeve 11 of the front end of middle sleeve 31 are consolidated corresponding to it
Fixed connection, the front end of spiral support bar 13 are fixedly connected on before middle sleeve 31 on short inwall so that spiral support bar 13 is right
Region between inner sleeve 11 and middle sleeve 31 is also divided into three by inner sleeve 11 and middle sleeve 31 while playing fixation
Not connected space, three rear ends of spiral support bar 13 are fixedly connected with three allotment stays 14, and allotment stay 14 is in inner sleeve
Support axially inner sleeve 11 and middle sleeve 31 is fixed between pipe 11 and middle sleeve 31, allotment stay 14 extends to outer

The length extended, the gap between outer tube 22 and middle sleeve 31 are slightly larger than the spiral sacculus in folded state during without gas
12 thickness, when spiral sacculus 12 is in gasless folded state, ejector sleeve 21 is promoted, ejector sleeve 21 drives outer tube 22 forward
Slide, can cover the spiral sacculus 12 in folded state in sliding outer cover pipe 22, until outer tube 22 slides into termination 17
Put.
When patient needs treatment, when patient needs the tracheae, blood vessel, oesophagus of the interlude of therapeutic purpose position more narrow
Or when blocking, this interlude tube wall can be expanded with the present invention, exemplified by this sentences tracheae, now outer tube 22 entangles
The spiral sacculus 12 and front end of outer tube 22 is located at the rear end of termination 17, outer tube 22 stretches into from patient oral cavity, in Marking ring 15 and
Under radiography Display Technique, Marking ring 15 is stretched into patient airway need to expand position, then pull back ejector sleeve 21, the band of ejector sleeve 21
Dynamic outer tube 22 slides axially backward along middle sleeve 31, and outer tube 22, which slides backward, causes the spiral sacculus in folded state
12 all expose, and syringe are accessed into the second joint 35, and injected gas thereto, gas inside inflation branch pipe 33 by entering
Inside middle sleeve 31, then entered in the space of three allotment being not communicated with stays 14, gone forward side by side simultaneously by the inside of middle sleeve 31
Enter into three centres of spiral support bar 13, and finally uniformly arranged in the stationary plane position of middle sleeve 31 by spiral sacculus 12
Passage is entered in spiral sacculus 12 so that spiral sacculus 12 is filled, and finally causes spiral sacculus 12 to fill into section
For sector state, now tracheal wall be expanded, oxygen can to there is the huge space between spiral sacculus 12 to enter in vivo,
So that the physical function of patient enough keeps normal during treatment, seal wire 32 is then sent into forward, seal wire 32 is from inner sleeve
11 front ends are stretched out needs treatment position up to reaching, and when treatment end, seal wire 32 is bounced back to inside inner sleeve 11, uses syringe
The internal gas of spiral sacculus 12 is extracted out from the second joint 35, retraction is in folded state after spiral sacculus 12 discharges into gas, now
Ejector sleeve 21 is promoted, ejector sleeve 21 drives the forward slip of outer tube 22 so that spiral sacculus of the covering of outer tube 22 in folded state
12。
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
