Suppose that getting property of a difficulty foreign body 15 is arranged in esophagus 14, owing to foreign body self, it can not be taken out by conventional method, otherwise very likely patient be caused the mortality injury; Perhaps, owing to patient's self physiological reason or reason economically, can not be by operation with its taking-up.So, can be easily with foreign body by Microendoscopic taking foreign body instrument of the present utility model, below in conjunction with Fig. 7～Figure 13 provide in esophagus, get getting property of difficulty foreign body the time the step sketch map, the detailed step of Microendoscopic taking foreign body instrument of the present utility model is described.
A. observe and insert guide wire, as shown in Figure 7, by putting into Esophagoscopes 16, observe the position at getting property of difficulty foreign body 15 places; By scale label on the Esophagoscopes 16, calibrate getting property of difficulty foreign body 15 apart from the degree of depth (for example, demarcating the near-end of difficult getting property foreign body 15 apart from the distance of patient's front tooth) of front tooth; And insert guiding steel wire 2 by the biopsy channel of Esophagoscopes 16, by observation, should guarantee that the degree of depth that guiding steel wire 2 inserts surpasses the degree of depth of foreign body in esophagus;
B. Stent Implantation as shown in Figure 8, takes out Esophagoscopes 16 under the prerequisite that keeps guiding steel wire 2, will extend into the inserter 3 of support 1 in patient's esophagus along guiding steel wire 2; Should guarantee that the degree of depth that inserter 3 stretches into is identical with the degree of depth of measurement, so that the front end of support 1 is positioned at the upper edge of getting property of difficulty foreign body 15 just;
C. releasing bracket as shown in Figure 9, is extracted steady pin 13, by the trocar sheath 6 of retracting backward, makes support 1 become the free wxpansion state by compressive state; Then the positioning wire 8 of drawing back is separated set winding 1-3 and positioning wire 8, so that support 1 becomes free state;
D. take out inserter, as shown in figure 10, inserter 3 and guiding steel wire 2 are taken out simultaneously, only keep support 1 and be arranged in esophagus 14, and guarantee that the backguy 11 on the support 1 is in the position that can touch with hands;
E. insert Esophagoscopes 16 and foreign body forceps, as shown in figure 11, utilize the visual effect of Esophagoscopes 16, Esophagoscopes 16 is extend in the foreign body chamber 12 of support 1, and put into foreign body forceps 17 by the biopsy channel of Esophagoscopes 16;
F. with getting property of support parcel difficulty foreign body, as shown in figure 12, under the visual effect of Esophagoscopes 16, utilize foreign body forceps 17 to clamp getting property of difficulty foreign body 15, it is pulled in the foreign body chamber 12 of support 1; By tension backguy 11, the right-end openings of support 1 can be become the reducing state, effectively reduced the right-hand member diameter of support 1, be convenient to support 1 smooth per os and be drawn out;
G. take out getting property of difficulty foreign body, as shown in figure 13, keeping backguy 11 tensions, foreign body forceps 17 to clamp under the state of difficult getting property foreign body 15, with the together per os taking-up from esophagus of Esophagoscopes 16, support 1, foreign body forceps 17, getting property of difficulty foreign body 15.
Microendoscopic taking foreign body instrument of the present utility model can be effectively with getting property of the difficulty foreign body in the esophagus, avoid the situation of operation taking foreign body, reduced patient misery, saved medical expense and avoided operation risk.Taking foreign body instrument of the present utility model is equally applicable to getting property of difficulty foreign body in getting property of gastric difficulty foreign body, the trachea (needing to cooperate bronchoscope to use).。Taking foreign body instrument of the present utility model, have simple for structure rationally, beneficial effect significantly and the advantage of being convenient to application.
