Embodiment 1

[0040] See attached Figure 2-6 , an anti-displacement esophageal stent kit comprising: an esophageal stent 5; a conveyor 6; a buffer fixing tube 7; a threader 8;

[0041] From figure 2 It can be seen from the figure that the esophageal stent 5 includes a stent body 51 and a fixed wire 52, the fixed wire 52 goes around the upper mouth of the stent body 51, and a fixed knot 521 is tied; image 3 It can be seen from the figure that the esophageal stent 5 is loaded in the distal end of the conveyor 6, and the fixing wire 52 extends from the proximal end of the conveyor 6; Figure 4 It can be seen from the above that, in the first embodiment, there is a through hole 71 in the middle of the buffer fixing pipe 7, and the buffer fixing pipe 7 is a circular frustum. ;From Figure 5 , Figure 6 It can be seen from the figure that the threader 8 is composed of a sheath tube 81 and a ferrule 82, and the ferrule 82 passes through the inner cavity of the sheath tube 81; The structure...

Embodiment 2

[0057] See attached figure 2 , 3 , 5, 10, 11, an anti-displacement esophageal stent device kit includes: esophageal stent 5; conveyor 6; threader 8; buffer fixing tube 9.

[0058] See attached Figure 10 , it can be known that the buffer fixing tube in the second embodiment has a concave hole 71, and the position of the concave hole 71 is located in the middle of the buffer fixing tube 7; the material of the buffer fixing tube 7 is silica gel or thermoplastic elastomer material. .

[0059] See attached Figure 11 Figures (a) and (b) in the middle are schematic diagrams of external fixation of the fixed line in Example 2, and the specific process is as follows:

[0060] 1) Insert the two fixing lines 52 respectively from both ends of the buffer fixing tube 9, and pass through the concave hole 71;

[0061] 2) Push the buffer fixing tube 9 into the nostril 2 along the fixing line;

[0062] 3) Properly tighten the two fixing lines 52, then tie the two fixing lines 52 and fix ...

Embodiment 3

[0065] see Figure 12 , two slender hoses 10 are bonded to the head end of the buffer fixing tube 7, the through hole of the hose 10 communicates with the through hole 71, and the two fixing lines 52 penetrate through the end of the through hole of the hose 10 respectively, and connect from the head end of the 71 Pass it out, and then fix the two fixing lines 52 with knots. The length of the hose 10 exceeds the pharynx 4 . Refer to Embodiment 1 for the rest of the process, which will not be repeated here.

Abstract

The invention relates to an anti-displacement esophageal stent apparatus bag. The esophageal stent apparatus bag comprises an esophageal stent, a conveyor, a threading apparatus and a buffer fixing pipe. A fixed line, on the esophageal stent, implanted into a diseased region is withdrawn outside a body, namely a portion of naris, through the threading apparatus, the fixed line is fixed on the buffer fixing pipe, and the purposes of the esophageal stent not shifting and not falling out are achieved.

Description

technical field [0001] The utility model belongs to the field of medical equipment, and in particular relates to a displacement-proof esophageal stent device package. Background technique [0002] In recent years, with the maturity of interventional technology, there are more and more types of stents. Among them, the application of esophageal stents in the treatment of esophageal stenosis, esophageal tracheal fistula and other esophageal diseases has gradually become the mainstream and achieved remarkable results. . The esophageal stent has the advantages of less trauma, quick effect, safety and convenience in the treatment of such diseases, especially for patients with poor physical conditions and a long course of disease. It is an effective treatment method that cannot be replaced by other treatment methods. [0003] Esophageal stents can be classified according to the covering condition: no covering, partial covering and full covering. But no matter what kind of stent i...
