The specific embodiment:
See also Fig. 1～Fig. 5, specific embodiment of the utility model is as follows: comprise a delivery sheath 1, delivery sheath 1 one ends are opening shape 2, another big caliber end is provided with operating grip 3, operating grip 3 connections one run through the pull bar 4 of delivery sheath 1, and pull bar 4 one ends are provided with the balloon-system 5 of controlled change diameter; Delivery sheath 1 is the hollow pipe of a flexibility, the one end is opening 2, the other end is connected with big caliber 6 one ends, one pull bar 4 is arranged in the delivery sheath 1, one end of pull bar 4 stretches out and is connected with balloon-system 5 from the opening 2 of delivery sheath 1, and the other end of pull bar 4 then flexibly connects with the operating grip 3 that is placed on the big caliber 6; Operating grip 3 has a handle bar 7 with female thread, the female thread of handle bar 7 connects as one with suitable operating grip 3 and the big caliber 6 of making of screw thread that big caliber 6 outside wall surface are provided with, when up time or inverse time turn operating grip 3, operating grip 3 is at big caliber 6 enterprising line displacements (reach or then move) and drive pull bar 4 and carry out rectilinear motion (along delivery sheath 1 axis) with it, balloon-system 5 also produces change in volume (being that cross-sectional diameter changes) with the motion of pull bar 4 simultaneously, the surface of bassoon path portion 6 also is provided with several numerical value labelling 9 graduation marks of being made up of millimeter unit, and each scale value then reflects the footpath value that diameter changed when the balloon-system corresponding with it 5 launched; Above-mentioned balloon-system 5 is a netted sacculus body that is formed by the braiding of many memory alloy wires, an end that constitutes many memory alloy wires of this sacculus is fixed by preceding stationary fixture 11, the other end is fixing by back stationary fixture 12, back stationary fixture 12 also has a through hole, the pull bar 4 that stretches out the opening 2 of delivery sheath 1 passes the through hole of back stationary fixture 12 and affixed with preceding stationary fixture 11, the internal diameter of back stationary fixture 12 greater than the external diameter of delivery sheath 1 so that its cover is fixed in opening 2 places of delivery sheath 1, when turn operating grip 3 (shown in Figure 1), along with the displacement of operating grip 3 on bassoon path portion 6, pull bar 4 also carried out rectilinear motion along delivery sheath 1 axis thereupon and made sacculus 5 that vary in diameter take place this moment, the numeric indicia 9 on bassoon path portion 6 surfaces is corresponding with the diameter value of sacculus 5, the diameter value of sacculus 5 when promptly the graduation mark of the numeric indicia 9 by bassoon path portion 6 surfaces just directly draws and is in this graduation mark; During use, operating grip 3 is positioned at the initial value position of numeric indicia 9, to be sacculus 5 by pull bar 4 stretch to be in shrinks bound state (shown in Figure 2), delivery sheath 1 is pierced in the tube chamber of branchofiberoscope, and be admitted to the precalculated position of human lung's segmental bronchi or lobar bronchi in company with branchofiberoscope, behind the in-position, the sacculus 5 of delivery sheath 1 pushed away stretch out branchofiberoscope, turn operating grip 3 makes the displacement retraction of pull bar 4 with operating grip 3, displacement along with pull bar 4, sacculus 5 launches (Fig. 3～shown in Figure 5) from the bound state expansion with the shape memory of himself gradually from swollen characteristic, at this moment can whether touch by the sacculus 5 that the viewer of branchofiberoscope is watched after the expansion with the internal face of body lumen 10, after the internal face of unfolded sacculus 5 walls and body lumen 10 touches fully gradually, just stop turn operating grip 3, according to the just accurate footpath value of this tube chamber 10 as can be known of the numeric indicia 9 on big caliber 6 surfaces.For example, when lumen diameter is minor diameter D1 (shown in Figure 3), 5 of sacculus slightly expansion launch to learn the footpath value of this tube chamber, and when tube chamber 10 diameters are intermediate diameters D2 (shown in Figure 4) or tube chamber 10 diameters when being maximum dimension D 3 (shown in Figure 5), sacculus 5 never launches fully until expansion fully.After measurement finishes, turn operating grip 3 makes it return to the initial value position of numeric indicia 9 again, pull bar 4 was stretched to sinciput and was made sacculus 5 revert to the contraction bound state this moment, just this utility model can be extracted out from branchofiberoscope, the doctor selects for use the support that matches with lumen diameter to insert and finishes intervene operation in this tube chamber fast according to measured lumen diameter.
See also Fig. 6～Figure 10, above-mentioned balloon-system 5 is at least two sacculus that are linked in sequence, and sacculus has the known diameter value after launching, and there is the labelling corresponding with sacculus 9 on handle bar 7 surfaces in the inserted delivery sheath bassoon path portion 6 of operating grip 3; Big caliber 6 is provided with a cavity 13, the handle bar 7 of operating grip 3 places in the cavity 13, the internal face of the surface of handle bar 7 and cavity 13 is shiny surface, and handle bar 7 can carry out reciprocal linear slide displacement in cavity 13, numeric indicia 9 (shown in Figure 6) is set on the surface of handle bar 7; One end of handle bar 7 and an end of pull bar 4 are affixed, and the other end of pull bar 4 is connected with the stiff end tool 8 of sacculus 5 one ends, and stiff end tool 8 and the connected mode of pull bar 4 can be solid welding is connected or stiff end tool 8 is provided with female thread and the screw thread of pull bar 4 ends is spirally connected; Sacculus 5 is two or three sacculus that is linked in sequence, its each sacculus the diameter after launching fully all different, sacculus 5 can be disengaged (releasing) in income (drawing in the delivery sheath 1) delivery sheath 1 and in delivery sheath 1 in delivery sheath 1, sacculus 5 can be a plurality of, but the best is three sacculus; During use, above-mentioned three sacculus that are linked in sequence 5 are taken in the delivery sheath 1 (shown in Figure 7) fully, the numeric indicia 9 of handle bar 7 is in initial scale mark at this moment, after then delivery sheath 1 being delivered to human body segmental bronchi and lobar bronchi precalculated position by branchofiberoscope, promoting operating grip 3 makes pull bar 4 that sacculus 5 is ejected delivery sheath 1, send and launch from bound state expansion gradually from swollen characteristic when first sacculus is pushed with self shape memory, whether the sacculus of watching after the expansion by the viewer of branchofiberoscope 5 can touch with the internal face of body lumen 10, if can touch fully with the internal face of body lumen 10, then can be according to the just accurate footpath value (shown in Figure 8) of the diameter D1 of tube chamber 10 as can be known of the numeric indicia 9 on big caliber 6 surfaces; If can not touch with the internal face of body lumen 10 after first sacculus launches fully, continue promoting operating grip 3 again is pushed second sacculus to send, second sacculus watching after the expansion do not touch with the internal face of body lumen 10, if can touch the accurate footpath value (shown in Figure 9) that then can measure this lumen diameter D2; When above-mentioned two sacculus that pushed out during all less than the survey lumen diameter, again the 3rd sacculus pushed out, the internal face of watching not with body lumen 10 touches, if can touch the accurate footpath value (shown in Figure 10) that then can measure this lumen diameter D3; The diameter of three above-mentioned sacculus can cover the known minimum and the maximum diameter value of the segmental bronchi or the lobar bronchi of human body fully, the measurement diameter range is big, the sacculus 5 easy to operate, that certainty of measurement is high and above-mentioned can be covered with a macromolecular material rete, so that watch the situation that the internal face of itself and body lumen 10 touches.
