Part foreign body smooth surface, it is difficult to clamp, such as more smooth bone foreign body or pearl.2. part foreign body is easily caught broken, and uses clamp once to take out, and needs repeatedly clamp, the longest.And it is caught broken rear section fine grained chippings and can enter less air flue.Such as Semen arachidis hypogaeae.③
The part foreign body that the time is longer in air flue, can stimulate tracheal wall granulation hyperplasia to encase foreign body periphery surface, after needing to clear up periphery granulation, just can carry out clamp.4. needed for part foreign body, operating time is long.Two is to enter basket shape foreign body forceps by bronchoscope, and basket shape foreign body forceps entangles foreign body after opening and takes out.1. this method there is problems in that
Space between bigger foreign body and tracheal bronchus wall is the least, and basket shape foreign body forceps can not fully open, it is impossible to entangles foreign body.2. the part foreign body that the time is longer in air flue, can stimulate tracheal wall granulation hyperplasia to encase foreign body periphery surface, after needing to clear up periphery granulation, its is possible to carry out entangling foreign body.③
Part foreign body extracts difficulty, needs longer operating time.4. to extract operation easier big for part foreign body.5. basket shape foreign body forceps is made up of four steel wires, and the gap between steel wire is relatively big, fixes foreign body the best, is prone to come off during using tracheascope that foreign body pulls out air flue.
As a example by the actual case run in the recent period.Certain patient, during containing dark plum, is strayed into trachea, causes severe dyspnea, and anoxia is obvious.Owing to dark plum shape subcircular is similar to the shape of trachea, after entrance trachea, the space between dark plum and tracheal wall is too small, and basket shape foreign body forceps cannot open and entangle dark plum.And the appearance of dark plum is thicker and soft dark plum meat, when using alligator forceps and biopsy forceps clamp, because stress point is the least, it is impossible to whole dark plum is taken out, but it is only capable of pincers and takes a fritter dark plum meat.The most repeatedly clamp repeatedly after, the gap expanded with tracheal wall after dark plum can be utilized to reduce, use basket shape foreign body forceps to extract dark plum, whole operation is the longest, and seriously, thrill is very much for patient's anoxia.
In general, at present for foreign body limited through bronchoscope removing method in air flue, part foreign body possibly cannot take out through bronchoscope, and needs operative treatment.

Detailed description of the invention
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figures 1 to 4, the sucker shape foreign bodies in airway extractor of the present invention, include conduit 1, the head end of described conduit 1 is provided with the union joint 2 for connecting syringe or vacuum extractor, the end of described conduit 1 is provided with the sucker shape thin film 3 that transparent or trnaslucent materials is made, sucker shape thin film 3 has transparent or semitransparent characteristic so that observe the relative position of foreign body and sucker thin film through sucker shape thin film 3, the convenient sucker position that adjusts, and be easy to observe sucker shape thin film 3 and avoid damage to mucosa with the relative position of airway mucus.Sucker shape thin film 3 light weight and there is toughness not cracky, it is simple to make film like, and be accommodated in conduit cavity.Sucker shape thin film 3 can recover sucker shape after having the deformation of certain elastic force balance, forms sucker shape at the out rear expansible of the intracavity from conduit 1.Described sucker shape thin film 3 can be selected for politef or polyethylene or PE engineering plastics are made.Described sucker shape thin film 3 is made up of thin film disk 31 and connecting tube 32, it is provided with diameter between described thin film disk 31 and connecting tube 32 and is slightly less than three road fold 33 of connecting tube 32 diameter, the thickness of described fold 33 is thicker than thin film disk 31, the diameter of fold 33 is again smaller than conduit 1 diameter, the diameter of described disk film 31 is more than the external diameter of conduit 1, the diameter of described conduit 1 is more than or equal to 2 millimeters, a diameter of 4-10 millimeter of described disk film 31, when the end of conduit 1 presses close to foreign body surface, catheter tip can be avoided too closely to be attached to the local of foreign body, thus the negative pressure in hindering conduit is conducted to sucker thin film surrounding.The thin film disk 31 of described sucker shape thin film 3 is provided with several groove stricture of vaginas 311, and the negative pressure being beneficial to conduit 1 spreads along groove to sucker shape thin film 3 periphery.
Operation principle: when being in resting state, the sucker shape thin film 3 of conduit 1 end is in catheter tip intracavity, when bronchoscope arrives above foreign body, inserts conduit 1 by bronchoscope working channels.After conduit 1 end arrives above foreign body, the union joint 2 of conduit 1 head end connects syringe, syringe is inflated from interface, the sucker shape thin film 3 making conduit 1 end blows out conduit 1 and stretches out the intracavity of conduit 1 and launch (thin film has certain elasticity can recover discoid) in the form of annular discs, blunt nosed soft seal wire 10 can be connected with in described conduit 1, blunt nosed soft seal wire 10 is because being soft, so bronchoscope can be passed through, can use blunt nosed soft seal wire 10, by conduit 1, sucker shape thin film 3 is released tube chamber, and be formed discoid.After sucker shape thin film 3 stretches out conduit 1, owing to the elastic stretch of self is sucker shape.Operated by bronchoscope, sucker shape thin film 3 is pressed close in air flue behind foreign body surface, the union joint 2 of conduit 1 head end is connect vacuum extractor (standing device in hospital) instead and opens negative pressure.Negative pressure is conducted by conduit 1, the gap between sucker shape thin film 3 and foreign body surface is made to form certain areas of vacuum or negative pressuren zone (because the usual surface of foreign body is the most rough, coating surface can not be used to be completely formed vacuum, but owing to catheter end can carry out lasting vacuum suction.The tight place that fits can form region of no pressure, and less closely place then forms negative pressuren zone).The air pressure official post sucker shape thin film 3 of sucker shape thin film 3 both sides firmly holds foreign body, and operation bronchoscope can take out rapidly foreign body.
