Abstract

Disclosed is a sinus balloon catheter. The sinus balloon catheter includes a body unit, a bending angle adjusting unit that includes a bending angle adjusting lever and a rotary plate, and a guide unit that includes a balloon, and has a pair of bending angle adjusting wires therein. The guide unit includes a first guide body, and a second guide body that is slidably provided in the first guide body, the balloon is provided on the second guide body, the rotary plate is connected to any one of the pair of bending angle adjusting wires to be rotated, and the other bending angle adjusting wire is maintained within the guide unit, and the guide unit is inserted into any one of a sphenoidal sinus, a frontal sinus, and a maxillary sinus.

Claims

1. A sinus balloon catheter comprising:

a body unit;

a bending angle adjusting unit that comprises a bending angle adjusting lever and a rotary plate;

a guide unit that comprises a guide channel in which a guide wire is arranged,

a first guide body with a pair of bending angle adjusting wires, a second guide body that is slidable along the first guide body, and a balloon that is provided on the second guide body; and

an extension that extends from a tip end of the body unit and encompasses a portion of the guide unit,

wherein a balloon position adjusting lever, that encompasses the second guide body and adjusts the sliding of the second guide body along the first guide body, is formed in the extension;

wherein the rotary plate is connected to any one of the pair of bending angle adjusting wires to be rotated, and at least a portion of each of the pair of bending angle adjusting wires is maintained within the first guide body, and

wherein the guide unit is configured to be inserted into any one of a sphenoidal sinus, a frontal sinus, and a maxillary sinus.

2. The sinus balloon catheter of claim 1, wherein a bending angle of a tip end of the guide unit is adjusted through rotation of the rotary plate.

3. The sinus balloon catheter of claim 1, wherein the body unit comprises a fluid injection part, and the sinus balloon catheter further comprises a fluid injection unit that is connected to the fluid injection part to inject a fluid into the balloon.

4. The sinus balloon catheter of claim 2, wherein the bending angle adjusting lever protrudes to the outside of the body unit, and the rotary plate is connected to the pair of bending angle adjusting wires while being rotated by the bending angle adjusting lever.

5. The sinus balloon catheter of claim 4, wherein the rotary plate has a disk shape.

6. The sinus balloon catheter of claim 5, wherein the rotary plate is provided with a mounting rod that protrudes from the rotary plate, and a mounting hole, into which the mounting rod is inserted, is formed in the body unit.

7. The sinus balloon catheter of claim 6, wherein the rotary plate is rotatable about the mounting rod while the mounting rod is inserted in the mounting hole.

8. The sinus balloon catheter of claim 7, wherein the rotary plate comprises a plurality of rotation rods that are arranged around the mounting rod, and any one of the pair of bending angle adjusting wires is connected to any one of the plurality of rotation rods.

9. The sinus balloon catheter of claim 8, wherein the rotary plate comprises:

a curved surface, into which the bending angle adjusting lever is inserted to be mounted on the curved surface; and

a flat side surface that is perpendicular to the curved surface.

10. The sinus balloon catheter of claim 9, wherein a lever mounting chamber, in which the bending angle adjusting lever is mounted, is formed on the curved surface, and the bending angle adjusting lever is mounted on a bottom surface of the lever mounting chamber by a resilient member.

11. The sinus balloon catheter of claim 9, wherein a fixing protrusion for fixing the bending angle of the guide unit is mounted at a lower end of the bending angle adjusting lever, and at least one fixing groove, into which the fixing protrusion is inserted, is formed on an upper surface of the body unit.

12. The sinus balloon catheter of claim 9, wherein a first magnetic groove, in which a first magnetic body having a first polarity is mounted, is formed on a side surface of the rotary plate, and a plurality of second magnetic grooves, in which second magnetic bodies having a second polarity that is opposite to the first polarity are mounted, are formed on a side surface of the body unit that faces a side surface of the rotary plate.

13. The sinus balloon catheter of claim 12, wherein the first magnetic groove is aligned with any one of the plurality of second magnetic grooves through rotation of the rotary plate.

14. The sinus balloon catheter of claim 1, wherein a fluid injection groove for injecting a fluid into the balloon is formed in the second guide body.
