Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a Eustachian tube balloon for ears, nose and throat. Background Art

[0002] Otolaryngology mainly treats diseases caused by the ears, nose, throat and other organs. When the patient's related conditions are more serious, Eustachian tube balloon dilatation surgery is required for treatment.

[0003] Eustachian tube balloon dilatation surgery is currently used to treat secretory otitis media, which is more difficult to treat. Generally, the first attempt is to resolve the obstruction of the Eustachian tube function through medication or Eustachian tube inflation, or large-scale puncture, or tympanic membrane self-tube. If the symptoms and discomfort of otitis media are still not improved, Eustachian tube balloon dilatation can be tried to resolve the Eustachian tube obstruction. At the same time, tympanoplasty and Eustachian tube balloon dilatation can be performed at the same time to resolve chronic otitis media caused by poor Eustachian tube function. Therefore, at present, Eustachian tube balloon dilatation is a good new surgical method for treating Eustachian tube obstruction.

[0004] In the prior art, some Eustachian tube balloons dredge the Eustachian tube by delivering air. This method is inefficient and it is difficult to expand the closed Eustachian tube to achieve the purpose of treatment. Therefore, we propose a Eustachian tube balloon for ENT to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a Eustachian tube balloon for ear, nose and throat to solve the problems raised in the above-mentioned background technology.

[0012] Preferably, the pushing mechanism further includes a handle, and the handle is arranged at one end of the screw rod.

[0013] Preferably, an injection tube is provided inside the injection hole.

[0014] Preferably, the limiting mechanism includes a limiting ring, a clamping block and a sliding rod, the limiting ring is arranged at one end of the Eustachian tube, a sliding hole is opened on the circumferential surface of the limiting ring, the sliding rod is arranged in the sliding hole, and the clamping block is arranged at one end of the sliding hole.

[0016] Preferably, a snap-fit ​​groove is provided on the circumferential surface of the threaded ring.

[0017] Preferably, the clamping block is clamped in the clamping slot.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. When treating a patient, if the Eustachian tube is blocked, the blockage of the Eustachian tube can be solved by expanding the balloon. When expanding the balloon, in order to make the balloon expand according to the different needs of different patients, the liquid in the liquid storage tube can be pushed into the delivery mechanism by the pushing mechanism, and then the liquid is delivered to the balloon by the delivery mechanism, so that the balloon can be expanded to solve the blockage of the Eustachian tube. By injecting liquid into the balloon, the balloon can be expanded more efficiently, and the amount of liquid required to expand the Eustachian tube can be more intuitively reflected to medical workers, so that the data can be recorded and analyzed, which is beneficial to the treatment of patients.

[0020] 2. When treating a patient, the balloon is very likely to fall off when the Eustachian tube and the balloon are placed in the patient's body. The limiting mechanism can ensure a more stable connection between the Eustachian tube and the balloon, thereby preventing the balloon from falling off during treatment and affecting the treatment.

After placement, if the Eustachian tube 31 is blocked, the balloon 40 can be expanded to solve the blockage of the Eustachian tube 31. When expanding the balloon 40, liquid can be injected into the liquid storage tube 10 in advance, and then the medical worker pushes the pushing mechanism. The liquid in the liquid storage tube 10 can flow into the conveying mechanism through the pushing mechanism, and then the liquid is conveyed to the balloon 40 through the conveying mechanism, so that the balloon 40 can expand. When conveying the liquid, a hollow ring 15 can be set inside the connecting hole 14, and the connecting ring 30 is threadedly connected to the hollow ring 15, so that the conveying mechanism can be disassembled after subsequent use or when the Eustachian tube 31 is damaged.

[0033] In this embodiment, the pushing mechanism includes a screw rod 20 and a liquid pushing block 22 . The screw rod 20 is disposed in the threaded hole 12 . The liquid pushing block 22 is disposed inside the liquid storage tube 10 . The liquid pushing block 22 is connected to the screw rod 20 .

[0034] Specifically, when pushing the liquid inside the liquid storage tube 10, since the screw rod 20 is threadedly arranged in the threaded hole 12, and the liquid pushing block 22 is arranged at one end of the screw rod 20, and the liquid pushing block 22 is arranged inside the liquid storage tube 10, the screw rod 20 can be rotated to drive the liquid pushing block 22 to move, and then the liquid can be pushed by the liquid pushing block 22.

[0035] In this embodiment, the pushing mechanism further includes a handle 21 , which is disposed at one end of the screw rod 20 .

[0036] Specifically, in order to enable the medical worker to rotate the screw rod 20 more conveniently, a handle 21 is provided at one end of the screw rod 20 , and the medical worker can push the liquid by rotating the handle 21 .

[0041] Specifically, when limiting the position of the balloon 40, since a threaded ring 41 is provided at one end of the balloon 40, and the threaded ring 41 is threadedly provided inside the Eustachian tube 31, in order to prevent the balloon 40 from rotating when the balloon 40 is placed in the patient's nasal cavity, thereby causing the balloon 40 to fall off, the balloon 40 can be limited by a limiting mechanism to prevent the balloon 40 from rotating.

[0042] Specifically, during specific use, a limiting ring 32 can be set at one end of the Eustachian tube 31, and a sliding hole 33 can be opened on the surface of the limiting ring 32, the sliding rod 53 is set inside the sliding hole 33, and the clamping block 50 is set at one end of the sliding rod 53. When there is no need to limit the balloon 40 and the balloon 40 needs to be replaced, the medical worker can manually pull the sliding rod 53 to release the clamping of the clamping block 50 on the threaded ring 41, and then the balloon 40 can be removed.

[0043] In this embodiment, the limiting mechanism further includes a telescopic rod 51 and a spring 52 . The telescopic rod 51 is disposed on the circumferential inner wall of the limiting ring 32 . The telescopic rod 51 is connected to the clamping block 50 . The spring 52 is disposed inside the telescopic rod 51 .

The telescopic rod 51 and the spring 52 can be used to squeeze the clamping block 50 in advance, and at this time the clamping block 50 can be clamped with the threaded ring 41, thereby preventing the balloon 40 from rotating.

[0045] In this embodiment, a clamping groove 42 is formed on the circumferential surface of the threaded ring 41 ; the clamping block 50 is clamped in the clamping groove 42 .

[0046] Specifically, in order to enable the clamping block 50 to be clamped with the threaded ring 41, a clamping groove 42 is opened on the surface of the threaded ring 41, and the inner wall of one side of the clamping groove 42 is set to an arc structure, and one side end of the clamping block 50 is also set to an arc structure.
