DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1: This embodiment Figure 1-Figure 6 As shown, in order to solve the problem that the size of the expander is difficult to change, the working process of the expander adjustment structure after external auditory canal stenosis surgery is disclosed, and the effect of the expander quickly adjusting its own structure is achieved. The specific contents are as follows:

[0033] An adjustment structure is provided at the upper end of the fixing block 5, and the adjustment structure can achieve the effect of changing the size of the elastic airbag 1 through the expansion plate 3;

[0034] The adjustment structure is provided with a rotating rod 6 and a moving cylinder 8 inside, and the rotating rod 6 is rotatably mounted on the upper end of the fixed block 5, and two sets of moving cylinders 8 are threadedly mounted on the outer side of the rotating rod 6, and a rotating block 7 is fixedly mounted on the upper end of the rotating rod 6;

[0035] An adjusting rod 9 is rotatably mounted on the outer side of the moving cylinder 8, and one end of the adjusting rod 9 away from the moving cylinder 8 is rotatably connected to the expansion plate 3, and four groups of expansion plates 3 and adjusting rods 9 are arranged at equal angles with respect to the moving cylinder 8, and the expansion plate 3 is an arc-shaped structure when viewed from above.

[0036] When using the dilator after external auditory canal stenosis surgery, first adjust the dilator to the required size as needed. In the process of adjusting the size of the dilator, it is necessary to rotate the rotating block 7 and make the rotating block 7 drive the rotating rod 6 to rotate. In the process of rotating the rotating rod 6, the two groups of moving cylinders 8 will move on the outside of the rotating rod 6. In the process of movement of the rotating rod 6, the expansion plate 3 will be pushed to move through the adjustment rod 9. In this process, the telescopic rod 4 will telescope and cooperate with the movement of the expansion plate 3. In the process of movement of the expansion plate 3, the elastic sleeve 2 and the elastic airbag 1 will undergo elastic deformation. At this point, the size adjustment process of the dilator is completed, so that the dilator can be effectively applied to different patients, thereby improving the scope of application of the dilator.

[0037] Embodiment 2: This embodiment is as follows Figure 1 and Figure 7 As shown, in order to solve the problem that the expander is difficult to inhale and exhale, the working process of the expander docking structure after external auditory canal stenosis surgery is disclosed, and the effect of the expander facilitating automatic inhalation and exhalation is achieved, and the specific contents are as follows:

[0038] A docking structure is provided inside the expansion plate 3, and the docking structure can achieve the effect of docking with the pressure gauge and changing the size of the elastic airbag 1;

[0039] A connector 10 and a mounting block 11 are provided inside the docking structure, and the connector 10 is fixedly mounted on the inner surface of the expansion plate 3, and the interior of the connector 10 is communicated with the interior of the elastic airbag 1, and the mounting block 11 is fixedly mounted inside the connector 10;

[0040] A sliding rod 12 is slidably mounted inside the mounting block 11, and a support spring 13 is sleeved on the outer side of the sliding rod 12. A sealing member 14 is fixedly mounted on one end of the sliding rod 12 close to the outlet of the connector 10, and the support spring 13 is located between the mounting block 11 and the sealing member 14.

[0041] The sealing member 14 forms an elastic structure with the mounting block 11 through the supporting spring 13 , and the sealing member 14 is in an isosceles trapezoidal structure in a front cross-sectional view.

[0042] When using the dilator after external auditory canal stenosis surgery, it is necessary to fill gas into the elastic airbag 1. During this process, the interface of the pressure gauge needs to be docked with the connector 10, and then gas can be filled into the elastic airbag 1. During this process, the connector of the pressure gauge needs to push the seal 14 and the connector 10 to move, and then the pressure gauge can fill gas into the elastic airbag 1 and expand the elastic airbag 1. In the process of the seal 14 and the connector 10 moving away from each other, the seal 14 will cause the sliding rod 12 to slide inside the mounting block 11, and the seal 14 will cooperate with the mounting block 11 to squeeze the support spring 13 and cause the support spring 13 to contract. After the pressure gauge is inflated, its connector can be removed from the inside of the connector 10. At this time, the support spring 13 will expand and push the seal 14 and the connector 10 to seal, so that the elastic airbag 1 is in an expanded state. Then the dilator can be placed inside the patient's ear canal, which can speed up the patient's recovery and relieve the patient's pain.

[0043] Embodiment 3: This embodiment is as follows Figure 1 , Figure 3 and Figure 5-Figure 6 As shown, in order to solve the problem that the expander cannot inhibit bacteria, the working process of the expander elastic airbag 1 after external auditory canal stenosis surgery is disclosed, and the expander can achieve the effect of inhibiting bacteria, and the specific contents are as follows:

[0044] An elastic airbag 1 and an elastic sleeve 2 fixedly installed inside the elastic airbag 1;

[0045] An expansion plate 3 is fixedly installed inside the elastic sleeve 2, a telescopic rod 4 is fixedly installed on the inner surface of the lower end of the expansion plate 3, and a fixing block 5 is fixedly installed on one end of the telescopic rod 4 away from the expansion plate 3;

[0046] The elastic airbag 1 is made of composite soft silicone material, the elastic sleeve 2 inside the elastic airbag 1 is made of soft rubber material, and both the elastic sleeve 2 and the elastic airbag 1 have antibacterial effects.

[0047] When using the dilator after surgery for external auditory canal stenosis, the elastic airbag 1 is made of silicone, which can reduce the pressure on the inside of the ear canal, and the elastic airbag 1 and the elastic sleeve 2 are both made of elastic materials, which can meet the effect of size adjustment. At the same time, the elastic airbag 1 and the elastic sleeve 2 have antibacterial effects, which can reduce the growth of bacteria inside the patient's ear canal, and after the elastic airbag 1 is placed in the patient's ear canal, it does not need to be removed for replacement, which reduces the patient's pain, speeds up the patient's recovery, and increases the overall practicality.
