Description
Technical field
The present invention relates to a kind of division of respiratory disease medicine equipment, more particularly to a kind of lower respiratory tract cavity obstruction expansion device.
Background technology
The bronchuses at different levels of tracheae, main bronchus and intrapulmonary are generally clinically collectively referred to as lower respiratory tract (low
respiratorytract).In air-breathing, air enters tracheae by nose or oral cavity, and tracheae is then and then bifurcated is formed
Two bronchuses, and enter in intrathoracic lung tissue.PCI the seventies Later development get up, it is in shadow
As under medical science (X-ray, ultrasound, CT, MRI etc.) guiding, by percutaneous puncture approach or by the original duct of human body, intervention is led
Pipe or apparatus are delivered to diseased region and carry out diagnosis radiography, treatment or tissue sampling.Tracheostenosis and foreign matters from being blocked are breathing systems
Unite common sympton, when serious can crisis life security, also without a kind of special apparatus in clinical practice before Lv.Chinese patent is public
A kind of tracheal dilator (patent No. 200620085891.6), including the steel wire rope in outer tube and insertion outer tube have been opened, with
And it is connected to the expansion steel wire and pull bar at steel wire rope two ends.It is to promote steel wire rope descending by pushing drawing rod, now steel wire
The expansion steel wire of rope front end is released from outer tube, so as to realize the effect of expansion patient's trachea.It is that outer tube is that it, which lacks road,
Hard tube, is difficult to be interspersed in tracheal strips, the expansion bore Lv Ding of steel wire is expanded in addition, it is difficult to meet practical application.Lower respiratory tract
Dilatation is to be beaten sacculus dilating catheter into lower respiratory tract obstruction stenosis, in medical imaging device by trachea-bronchial epithelial cell
Guiding and monitoring under, sacculus is expanded, make upper airway stricture position expand, increase respirator body flow.Existing product
Due to the limitation in structure, be expanded in operation specified pressure or shrink back sheath time it is longer, bring risk to operation.
The content of the invention
The technical problem to be solved in the present invention be how to overcome prior art exist defect there is provided one kind it is simple in construction,
Interspersed convenient, expansion ratio is whole Quick trachea dilater.Lower respiratory tract cavity blocks expansion device.
In order to solve the above technical problems, this lower respiratory tract cavity obstruction expansion device include wire leading pipe, it is proximal stent pipe, remote
End expansion pipe and two-part cucurbit sacculus, the two-part cucurbit sacculus include proximal balloon and distal balloon catheter, and the near-end expands
Open pipe and distal dilation pipe is fastened on wire leading pipe both sides, wherein proximal stent pipe extends to proximal balloon, distal dilation pipe
Extend to distal balloon catheter.It is so designed that, by sacculus Discrete control, uses the gas outlet closing of conventional tubular instead sidewall pores equal
The improved procedure of even outlet so that the scope control that operation equipment is expanded to the obstructive position of lower respiratory tract trachea-bronchial epithelial cell
System is more accurate and fine.
As optimization, the proximal balloon end is cecum.It is so designed that, stops that respiratory tract interior air-flow enters expansion and managed,
Ensure that the air-flow in expansion pipe is completely used for filling cucurbit sacculus, and then ensure being precisely controlled for cucurbit balloon expandable
As optimization, proximal balloon side wall is provided with some oval ventholes.It is so designed that, it is ensured that in sacculus
The air-flow that is filled with uniformly spread.
As optimization, the distal balloon catheter end is cecum.It is so designed that, stops that respiratory tract interior air-flow enters expansion and managed,
Ensure that the air-flow in expansion pipe is completely used for filling cucurbit sacculus, and then ensure being precisely controlled for cucurbit balloon expandable
As optimization, its side distal balloon catheter wall is provided with some oval ventholes.It is so designed that, it is ensured that in sacculus
Air-flow is filled with uniformly to spread.
As optimization, the proximal stent pipe is away from the 10~20mm of proximal balloon.
As optimization, the distal dilation pipe stretches into 10~20mm of distal balloon catheter.
As optimization, the venthole perforate on venthole and distal balloon catheter in the proximal balloon is in opposite direction.So
Design so that two air bag convection current inflations above and below cucurbit sacculus, so as to accomplish that overall uniform expansion, rather than side are rapidly inflated
Become big.
A kind of lower respiratory tract cavity obstruction expansion device of the present invention is simple in construction, easy to use, by sacculus Discrete control,
Use the gas outlet closing of conventional tubular the improved procedure of the uniform outlet of sidewall pores instead so that operation equipment is to lower respiratory tract gas
The scope control that pipe, bronchial obstructive position are expanded is more accurate and fine.
Brief description of the drawings
A kind of lower respiratory tract cavity obstruction expansion device of the invention is described further below in conjunction with the accompanying drawings：
Fig. 1 be this lower respiratory tract cavity obstruction expansion device planar structure schematic diagram (bold portion represents visual in figure
Structure, dotted portion represents perspective structure).
In figure：1- wire leading pipes, 2- proximal stents pipe, 3- distal dilations pipe, 4- proximal balloons, 5- distal balloon catheters, 6- outlets
Hole.
Embodiment
As shown in figure 1, this lower respiratory tract cavity obstruction expansion device includes wire leading pipe 1, proximal stent pipe 2, distal dilation
Pipe 3 and two-part cucurbit sacculus, the two-part cucurbit sacculus include proximal balloon 4 and distal balloon catheter 5, the proximal stent pipe
2 and distal dilation pipe 3 be fastened on the both sides of wire leading pipe 1, wherein proximal stent pipe 2 extends to proximal balloon 4, distal dilation pipe
3 extend to distal balloon catheter 5.By sacculus Discrete control, the gas outlet closing of conventional tubular is used instead sidewall pores uniform outlet
Improved procedure so that the scope control that operation equipment is expanded to the obstructive position of lower respiratory tract trachea-bronchial epithelial cell is more
It is accurate and fine.
The end of proximal balloon 4 is cecum, stops that respiratory tract interior air-flow enters expansion and managed, it is ensured that the air-flow in expansion pipe
It is completely used for filling cucurbit sacculus, and then ensures being precisely controlled for cucurbit balloon expandable.If the side wall of proximal balloon 4 is provided with
Do the venthole 6 of ellipse, it is ensured that the air-flow that is filled with sacculus uniformly spreads.The end of distal balloon catheter 5 is cecum, and stop is exhaled
Inhale road interior air-flow and enter expansion pipe, it is ensured that the air-flow in expansion pipe is completely used for filling cucurbit sacculus, and then ensures cucurbit sacculus
That expands is precisely controlled.Its wall of side distal balloon catheter 5 is provided with some oval ventholes 6, it is ensured that be filled with air-flow in sacculus
Uniform diffusion.The proximal stent pipe 2 is away from the 410~20mm of proximal balloon.The distal dilation pipe 3 stretches into distal balloon catheter
510~20mm.Venthole 6 in the proximal balloon 4 and the perforate of venthole 6 on distal balloon catheter 5 are in opposite direction so that cucurbit
Two air bag convection current inflations above and below sacculus, so that accomplish overall uniform expansion, rather than change is rapidly inflated greatly in side.
