8 are fixed as one, and fixation is blocked by circlip 5 in one end that middle sleeve 4 is located at tracheae 14, and because outside circlip set 6 and H-type sacculus 3
Side is fixed as one, so that middle sleeve 4 and H-type sacculus 3 are relatively fixed after circlip 5 is blocked and fixed, clip spring seat 7 is with middle sleeve 4
It is fixed as one, when 17 thickness of tracheoesophageal fistula of different patients is not of uniform size, middle sleeve 4, middle sleeve 4 is pulled by seal wire 9
It drives clip spring seat 7 to jack up circlip 5, spacing between H-type sacculus 3 is adjusted, to be used to be suitable for different trouble
Person.
Preferably, the quantity for blocking valve 10 is two referring to Figure 11-12, it is convex to be provided with arc on closure valve 10
The arc convex in face, two closure valves 10 is oppositely arranged inwardly along outer tube 1.There are two being arranged in middle sleeve 4 in opposite directions
Valve 10 is blocked, closure valve 10 is hemispherical, and two closure valves 10 are fixed on 4 inner passage two sides of middle sleeve, and arc is convex
It facing towards inside, blocks valve 10 and is passed through for seal wire 9, after extracting seal wire 9 out, block valve 10 and close, two towards relatively
Closure valve 10 make oesophagus 15 and tracheae 14 completely separated.
Preferably, two medial surfaces for being close to tracheoesophageal fistula 17 after H-type sacculus 3 is full are taper.When outer tube 1 is by H
After type sacculus 3 is transported to accurate location, outer tube 1 is taken out, H-type sacculus 3 is filled by gas tube 2 and sacculus one-way pressure maintaining valve 11
Gas, after H-type sacculus 3 is full, two medial surfaces have certain taper, are in from the side isosceles trapezoid, because of 17 side of tracheoesophageal fistula
Edge is also to extend with tapered, and to surrounding, therefore using can be right after inflation is full with tapered H-type sacculus 3
Tracheoesophageal fistula 17 and its periphery are blocked completely.
When needing to treat, the H-type sacculus 3 and its dependency structure of unaerated state and seal wire 9 are filled in into outer tube 1
In, H-type sacculus 3, at contraction state is closed up, the outer tube 1 for filling in dependency structure is protruded into from tracheae 14, in seal wire in outer tube 1
Under 9 guide function, 1 front end bending section of outer tube passes through tracheoesophageal fistula 17, at this time by corresponding 15 part of oesophagus of H-type sacculus 3
One end first released from outer tube 1, then small part of gas is poured from sacculus one-way pressure maintaining valve 11, so that 15 part of oesophagus
H-type sacculus 3 it is slightly full, tracheoesophageal fistula 17 can be blocked so that when outer tube 1 is extracted out 14 part of tracheae H-type sacculus 3
It can be detached from outer tube 1, outer tube 1 is extracted out in vitro, it is made to 3 inner inflatable of H-type sacculus by sacculus one-way pressure maintaining valve 11
Full, H-type sacculus 3 is full and is in H-type, blocks tracheoesophageal fistula 17 completely after H-type sacculus 3 is full, finally extracts seal wire 9 out,
After seal wire 9 is extracted out, closure valve 10 of the middle sleeve 4 in 15 position open end of oesophagus is closed completely, so that tracheae 14 and oesophagus 15
Between separate completely.
The innovation of the invention consists in that:
1.H type sacculus 3 is full and is in H-type, blocks tracheoesophageal fistula 17 completely after sacculus is full, finally extracts seal wire 9 out,
After seal wire 9 is extracted out, closure valve 10 of the middle sleeve 4 in 15 position open end of oesophagus is closed completely, so that tracheae 14 and oesophagus 15
Between separate completely.
2. taking out outer tube 1 after H-type sacculus 3 is transported to accurate location by outer tube 1, passing through gas tube 2 and sacculus list
H-type sacculus 3 is inflated to pressure retaining valve 11, after H-type sacculus 3 is full, two medial surfaces have certain taper, from the side in isosceles ladder
Shape, because 17 edge of tracheoesophageal fistula is also to extend with tapered, and to surrounding, therefore using with tapered H-type ball
Capsule 3 can block completely tracheoesophageal fistula 17 and its periphery after inflation is full.
3. outer tube 1 of the invention is L-shaped, bending part angle is obtuse angle, is inserted into tracheoesophageal fistula 17 convenient for outer tube 1,
In early period, the H-type sacculus 3 in closed configuration, two sacculus series connection, one end side position and gas tube 2 are provided in outer tube 1
Connection, center are provided with balloon tube 12, and centre has seal wire 9 to pass through, and other end closing, seal wire 9 is stretched out from the other end.
4. 2 other end of gas tube and the external air charging system of sacculus one-way pressure maintaining valve 11() it is connected to, sacculus one-way pressure maintaining valve 11
The structure of (having the function of unidirectionally inflating pressure maintaining) are as follows: ball column position is small sacculus, can pass through small sacculus in inflation
Expanded state reaction H-type sacculus 3 expanded state, gas tube 2 be used to inflate.
5. the effect of seal wire 9 is that guidance H-type sacculus 3 is walked in outer tube 1 to accurate location, the effect of outer tube 1 is fortune
H-type sacculus 3 is sent, outer profile is smooth to more easily pass tracheoesophageal fistula 17.
6. circlip set 6 is fixedly connected with the side for being in tracheae 14 on H-type sacculus 3,5 He of circlip is provided in circlip set 6
Clip spring seat 7, circlip 5 are in conical surface shape, and circlip 5 is along the circumferential direction wave-shaped, and 7 end of clip spring seat is also in conical surface shape.Retaining ring 8 and ball
The fixation of cyst membrane 13 is fixed as one with middle sleeve 4.
7. the retaining ring 8 of one end and 3 outside of H-type sacculus positioned at 15 position of oesophagus of middle sleeve 4 is fixed as one, middle sleeve
Fixation is blocked by circlip 5 in 4 one end for being located at tracheae 14, and because circlip set 6 be fixed as one on the outside of H-type sacculus 3 so that in card
Spring 5 block it is fixed after middle sleeve 4 and H-type sacculus 3 it is relatively fixed, clip spring seat 7 is fixed as one with middle sleeve 4, as different patients
17 thickness of tracheoesophageal fistula it is not of uniform size when, by seal wire 9 pull middle sleeve 4, middle sleeve 4 drive clip spring seat 7 circlip 5 is pushed up
It rises, spacing between H-type sacculus 3 is adjusted, to be used to be suitable for different patients.
8. there are two opposite closure valves 10 for setting in middle sleeve 4, closure valve 10 is hemispherical, two closure valves
Film 10 is fixed on 4 inner passage two sides of middle sleeve, and arc convex blocks valve 10 and pass through for seal wire 9, work as extraction towards inside
After seal wire 9, blocks valve 10 and close, two make oesophagus 15 and tracheae 14 completely separated towards opposite closure valve 10.
9. the H-type sacculus 3 and its dependency structure of unaerated state and seal wire 9 are filled in outer tube 1 when needing to treat
In, H-type sacculus 3, at contraction state is closed up, the outer tube 1 for filling in dependency structure is protruded into from tracheae 14, in seal wire in outer tube 1
Under 9 guide function, 1 front end bending section of outer tube passes through tracheoesophageal fistula 17.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
