Description

Technical Field

[0001] This utility model relates to the field of sinus surgery, and particularly to a double-balloon Y-shaped drainage device for sinus surgery. Background Technology

[0002] During sinus surgery, the nasal cavity needs to be rinsed with a solution to remove foreign objects and expose the surgical field. Therefore, a drainage tube is needed to extract the solution accumulated inside the nasal cavity.

[0003] Most existing nasopharyngeal drainage devices use a single-lumen circular balloon catheter with a fixed inner diameter for the single drainage channel. When the negative pressure of the balloon is too high, it can easily damage the mucosa and compress the drainage channel, causing it to collapse. In addition, the contact surface of the inflated balloon is uniformly circular, which makes it difficult to fit the elliptical posterior nasal anatomical structure.

[0004] Therefore, it is necessary to provide a new double-balloon Y-shaped drainage device for sinus surgery to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a double-balloon Y-shaped drainage device for sinus surgery that is easy to use and prevents collapse and damage to the nasal mucosa.

[0006] To solve the above-mentioned technical problems, the present invention provides a double-balloon Y-shaped drainage device for sinus surgery, comprising: a corrugated tube, with drainage tubes symmetrically installed at the top end of the corrugated tube, the corrugated tube and the drainage tubes forming a "Y" shape; a first airbag with an arc-shaped edge installed on the side wall of the top end of the corrugated tube, and a second airbag with an elliptical surface installed on the side wall of the drainage tube.

[0007] Preferably, a first connector is symmetrically installed on the side wall of the bellows, and a valve is installed on the side wall of the first connector.

[0008] Preferably, one of the first connectors is connected to the first airbag via a hose, and the other first connector is connected to the second airbag via the hose.

[0009] Preferably, a second connector is installed at the bottom end of the bellows.

[0010] Preferably, a spring is installed inside the top end of the drainage tube, and a section of the drainage tube with the spring installed inside is located inside the second airbag.

[0011] Compared with related technologies, the double-balloon Y-shaped drainage device for sinus surgery provided by this utility model has the following beneficial effects: This invention provides a double-balloon Y-shaped drainage device for sinus surgery. After the patient is anesthetized, the drainage tube and the corrugated tube are inserted into the oral cavity. The drainage tube passes through the nasopharynx and enters the nasal cavity. Gas is injected into the first balloon, causing it to inflate and compress the patient's nasopharynx, initially fixing the drainage tube and the corrugated tube. Then, gas is injected into the second balloon, causing the elliptical second balloon to inflate and fit tightly against the patient's nasal cavity. The large contact area between the second balloon and the nasal cavity improves the seal. During the ventilation of the second balloon, forceps are used to grasp the inlet of the drainage tube and adjust its position to prevent the inlet from contacting the nasal cavity. The drainage tube is kept open at its inlet by contact with the nasal lining. Multiple airbags are fixed inside the patient's nose, providing multi-point fixation to increase its stability and reduce internal pressure, preventing damage to the mucosa. A corrugated tube is placed inside the patient's mouth to resist occlusal deformation and prevent collapse that could affect drainage. A section of the drainage tube containing a spring is located inside the second airbag. As the second airbag inflates, it compresses the drainage tube inward, and the spring supports the inner wall of the tube, preventing collapse and ensuring effective drainage.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please see Figures 1 to 3 , Figure 1 A schematic diagram of a preferred embodiment of the double-balloon Y-shaped drainage device for sinus surgery provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the bellows. Figure 3This is a schematic diagram of the present invention placed inside the oral cavity and nasal cavity. A double-balloon Y-shaped drainage device for sinus surgery includes a corrugated tube 1, with drainage tubes 4 symmetrically installed at the top end of the corrugated tube 1, forming a "Y" shape with the corrugated tube 1 and the drainage tubes 4; a first airbag 2 with an arc-shaped edge is installed on the side wall of the top end of the corrugated tube 1, and a second airbag 3 with an elliptical surface is installed on the side wall of the drainage tube 4. During sinus surgery, the patient is first anesthetized. Then, the drainage tube 4 and the corrugated tube 1 are inserted into the oral cavity. The drainage tube 4 passes through the nasopharynx and enters the nasal cavity. Gas is injected into the first airbag 2, causing it to inflate and compress the nasopharynx, thus initially fixing the drainage tube 4 and the corrugated tube 1. Next, gas is injected into the second airbag 3, causing the elliptical second airbag 3 to inflate and fit tightly against the patient's nasal cavity. The large contact area between the second airbag 3 and the nasal cavity improves the seal. During the ventilation of the second airbag 3, forceps are used to hold the entrance of the drainage tube 4 and adjust its position to avoid contact between the entrance of the drainage tube 4 and the nasal skin, keeping the entrance of the drainage tube 4 within the patient's nasal cavity. The internal structure is unobstructed; multiple airbags are fixed inside the patient's nose, and the drainage tube is fixed at multiple points to increase its stability. This multi-point fixation also appropriately reduces the pressure inside the airbags, preventing excessive pressure from damaging the mucosa. Two drainage tubes 4 are distributed inside the two nasal cavities, facilitating simultaneous suction of fluid from both cavities. A corrugated tube 1 is placed inside the patient's mouth; its high rigidity resists deformation due to biting, preventing internal collapse and ensuring effective drainage. A section of the spring 9 installed inside the drainage tube 4 is located inside the second airbag 3. When the second airbag 3 inflates, it compresses the drainage tube 4 inwards, and the spring 9 provides support to the inner wall of the drainage tube 3, preventing internal collapse and ensuring effective drainage.

[0016] The corrugated pipe 1 has first connectors 5 symmetrically installed on its sidewalls, and valves 6 are installed on the sidewalls of the first connectors 5. One of the first connectors 5 is connected to the first airbag 2 through a hose 8, and the other first connector 5 is connected to the second airbag 3 through the hose 8. In order to use a syringe to engage with the connectors 5, gas is injected into the first airbag 2 and the second airbag 3 through the syringe to inflate the first airbag 2 and the second airbag 3, and the valves 6 are closed to keep the first airbag 2 and the second airbag 3 in an inflated state.

[0017] The bottom end of the corrugated tube 1 is equipped with a second connector 7. In order for the second connector 7 to connect with the drainage bag, the corrugated tube 1 and the drainage tube 4 are made to generate suction. When the patient is undergoing sinus surgery, the drainage tube 4 sucks out the liquid inside the nasal cavity and exposes the surgical field.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
