The stent assembly includes a branch tube 1 and a guide tube 2 arranged in a T-shape, wherein the branch tube 1 is connected to the guide tube 2.

[0028] A support assembly comprising a collar 3 sleeved on the outside of the guide tube 2 and fastening mechanisms 4 provided on both sides of the collar 3, wherein the two sets of fastening mechanisms 4 have different lengths and are adjustable structures that can be locked with the collar 3 after adjustment; and

[0029] A protection assembly, comprising an introduction tube sleeve 5 fixedly connected to one side of the collar 3, wherein the introduction tube sleeve 5 is movably connected to the introduction tube 2 via an introduction tube head 52;

[0030] Example 1

[0031] Please refer to the attached Figure 1 , attached Figure 1 The branch tube 1 in the actual use process includes an upper branch end and a lower branch end, wherein the upper branch end and the lower branch end are respectively arranged at both ends of the branch tube 1, and the end with a longer straight line distance from the end to the guide tube 2 is the upper branch end, and vice versa.

[0032] At the same time, during the treatment process, the upper branch end is first inserted into the tracheostomy, and then the angle of the device is adjusted to insert the lower branch end into the tracheostomy, leaving only the guide tube 2 outside the trachea, and then using the guide tube 2,

[0033] Specifically, refer to Figures 8-14 , can be used as shown below

[0034] Step S1: pinch the lower end of the branch tube 1 with your index finger and thumb, and fold the lower end of the branch tube 1. Figure 8 As shown;

[0035] Step S2: Clamp the folded part with hemostatic forceps, such as Figure 9 As shown;

[0036] Step S3: insert the distal trachea through the tracheostomy, such as Figure 10 As shown;

[0037] Step S4: Loosen the hemostatic forceps, clamp the upper branch end of the branch tube 1, and slowly push it into the tracheostomy. Figure 11 As shown;

[0038] Step S5: Loosen the hemostatic forceps at the upper end of the branch tube 1, and use another hemostatic forceps to push the entire branch tube 1 into the branch tube. Figure 12 As shown;

[0039] Step S6: Pull the guide tube 2 forward until the upper branch end of the branch tube 1 is placed in a suitable position, such as Figure 13 As shown;

[0040] Step S7: Push the ring 3 to the bottom and place it in the ring groove 21 that contacts the skin surface. Figure 14 shown.

[0041] As a further solution of the present invention: a stable tracheobronchial stent suitable for treating laryngeal tracheal stenosis, characterized by further comprising a venturi tube 6, wherein the inner portion of the end of the guide tube 2 away from the branch tube 1 is clamped to the venturi tube 6;

[0042] Example 2

[0043] When gas injection is required, the venturi tube 6 can be inserted into the guide tube 2 to accelerate the input or output of gas, thereby improving the efficiency of gas circulation.

[0044] Example 3

[0045] When liquid needs to be injected, the venturi tube 6 can be removed from the guide tube 2 to achieve the normal liquid flow function of the guide tube 2.

[0046] As a further solution of the present invention: a stable tracheobronchial stent suitable for treating laryngeal tracheal stenosis, in which the support assembly comprises an outer ring 31 fixedly connected to the outside of the collar 3, a fastening mechanism 4 comprising a connecting rod 41 and a suction cup 42 fixedly connected to one end of the connecting rod 41, wherein a through hole 33 with a hole clip 34 is formed inside the outer ring 31, and an anti-slip pad 43 and a clamping pad 44 are fixedly connected to the outer periphery of the connecting rod 41, and the anti-slip pad 43 and the clamping pad 44 can move with the connecting rod 41 and be clamped to the hole clip 34;

[0047] Example 4

[0048] See also Figure 1 、 Figure 4 as well as Figures 8-14 , it can be seen that when the ring 3 is used to fix the device to the tracheostomy according to step S7 of the first embodiment, there is a problem that the ring 3 cannot fit the tracheal skin, or the position of the branch tube 1 is deformed after barely fitting;

[0049] At this time, after the two unequal length fastening mechanisms 4 are moved, the card pad 44 passes through the hole card 34 and fits with one side of the hole card 34, and the anti-slip pad 43 can fit with the other side of the hole card 34. The two unequal length fastening mechanisms 4 can fit with the inclined neck, thereby achieving the fixing operation of the equipment without changing the position of the branch pipe 1, and the fixing effect is good.

[0050] As a further solution of the present invention: a stable tracheobronchial stent suitable for treating laryngeal tracheal stenosis, wherein a plurality of groups of equally spaced annular grooves 21 are formed inside the guide tube 2, and an inner clamp 32 adapted to the annular grooves 21 is fixedly connected inside the collar 3;

[0051] Example 5

[0052] By providing the ring grooves 21 at equal intervals, the position of the collar 3 can be easily adjusted.

[0053] As a further solution of the present invention: a stable tracheobronchial stent suitable for treating laryngeal tracheal stenosis, the protective component is made of silicone throughout, and the guide tube sleeve 5 in the protective component is fixedly connected to the outer ring 31 by a connecting rope 51.

[0055] As a further solution of the present invention: a stable tracheobronchial stent suitable for treating laryngeal tracheal stenosis, both ends of the branch tube 1 are chamfered;

[0056] Example 6

[0057] By chamfering the two ends of the branch tube 1, the friction between the branch tube 1 and the tracheostomy can be reduced during the process of the branch tube 1 entering the tracheostomy, thereby reducing damage to the tracheostomy or tracheal tissue.

[0058] The working principle of the utility model is: during the treatment process, the upper branch end is first inserted into the tracheostomy, and then the angle of the device is adjusted to insert the lower branch end into the tracheostomy, and only the guide tube 2 is left outside the trachea, and then the guide tube 2 is used.

[0059] Specifically, refer to Figures 8-14 , can be used as shown below

[0060] Use your index finger and thumb to pinch the lower end of the branch tube 1 and fold it. Figure 8 As shown;

[0061] Clamp the folded area with hemostats, such as Figure 9 As shown;

[0062] Inserted into the distal trachea through a tracheostomy, such as Figure 10 As shown;

[0063] Loosen the hemostatic forceps, clamp the upper branch end of branch tube 1, and slowly push it into the tracheostomy. Figure 11 As shown;

[0064] Loosen the hemostatic forceps at the upper end of branch tube 1 and use another hemostatic forceps to push the entire branch tube 1 into the tube. Figure 12 As shown;

[0065] Pull the guide tube 2 forward until the upper branch end of the branch tube 1 is placed in the appropriate position, such as Figure 13 As shown;

[0066] Push the ring 3 to the bottom and place it in the ring groove 21 that contacts the skin surface. Figure 14 shown; then

[0067] In accordance with Figure 4 When the ring 3 is used to fix the device to the tracheostomy, there is a problem that the ring 3 cannot fit the tracheal skin, or the position of the branch tube 1 is deformed after it is barely fitted;

[0068] At this time, after the two unequal length fastening mechanisms 4 are moved, the card pad 44 passes through the hole card 34 and fits with one side of the hole card 34, and the anti-slip pad 43 can fit with the other side of the hole card 34. The two unequal length fastening mechanisms 4 can fit with the inclined neck, thereby achieving the fixing operation of the equipment without changing the position of the branch pipe 1, and the fixing effect is good.

[0069] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
