Abstract

A surgical balloon which is provided with a plurality of balloons so that a fixing property and a shielding property are simultaneously satisfied, and prevents a liquid or a gas from flowing from one area in the body to another area thereof. The surgical balloon is further provided with a balloon fixing device, a drain for draining water from the front nostril and a tube for supplying rinsing water into the nasal cavity so that a surgical operation using an endoscope is carried out inside the nasal cavity with the nasal cavity filled with a water flow. A high-pressure balloon having a fixing property and a low-pressure balloon having a shielding property are combined, and the balloon is pulled from the periphery of the front nostril so as to be secured; thus, a large amount of water supply and water drain are carried out through the front nostril. Therefore, it is possible to carry out a nose surgical operation using an endoscope in a water flowing, a strong rinsing operation after the surgical operation and a diagnosis inside the nasal cavity using a ultrasonic wave.

Claims

1. A surgical balloon comprising, an aggregate of a plurality of balloons closely located with each other,

wherein in order to close a space connecting one area in a body to another area thereof so as to block a liquid or a gas flowing through the space, at least one balloon is press-adhered to a portion adjacent to bone tissue, cartilage tissue or hard tissue so as to be fixed thereon while other balloons closely adjacent thereto are indirectly fixed and allowed to expand with the fixed position being maintained, so as to shield a peripheral area;

wherein the aggregated balloons include balloons having a high inner pressure and balloons having a low inner pressure that are closely located with each other, the balloons having a high inner pressure being press-adhered and fixed onto a nasal cavity or a rear nostril with other balloons adjacent thereto being allowed to expand to block the nasal cavity and throat heads from communicating with each other

wherein a shielding balloon having a low inner pressure contains a balloon inside having a high inner pressure while keeping a positional relationship with contact faces being maintained so that the shielding balloon having a low inner pressure, located outside, is allowed to expand in a direction opposite to the contact face with the fixed balloons having a high inner pressure, located inside thereof, thereby exerting a pressing force in a specific direction.

2. The surgical balloon according to claim 1, wherein a balloon having a high inner pressure is allowed to expand in the rear nostril on the throat heads side or the nasal cavity side so as to be held and fixed therein so that a balloon having a low pressure and containing the balloon having a high inner pressure is allowed to press a membrane located on the periphery thereof while maintaining a stable position at an area from the rear nostril to the nasal cavity.

3. The surgical balloon according to claim 2, which further comprises a tube that reaches the mouth cavity side from the nasal cavity by penetrating the balloon held at the rear nostril so that rinsing water is sent from the mouth cavity side into the nasal cavity or waste fluid is sent from the nasal cavity side to the mouth cavity side.

4. The surgical balloon according to claim 3, which further comprises a surgical balloon fixing device that forms a face virtually perpendicular to a direction connecting the rear nostril to the front nostril without interrupting surgical operations from the front nostril by covering a portion of a face from a philtrum to cheeks, so as to cope with a pulling force from the rear nostril, and that also fixes an expanding tube of the surgical balloon while pulling it from the rear nostril side to the front nostril side by attaching a fixing member for pinching and fixing the tube thereto.

5. The surgical balloon according to claim 1, which further comprises a surgical balloon fixing device that has a front nostril window-opening device which maintains a surgical viewing field by pressing the front nostril from the inside, and covers a portion from the periphery of the outlet of the front nostril to the outer surface of a nose so as to cope with a pulling force from the rear nostril, and that also fixes an expanding tube of the surgical balloon while pulling it from the rear nostril side to the front nostril side by attaching a fixing member for pinching and fixing the tube thereto.

6. The surgical balloon according to claim 5, which further comprises a nose drain that is held on the outside of the front nostril and attached to the face so that fluids coming from the front nostril are drained.

7. The surgical balloon according to claim 6, which further comprises a soft nose water-supplying tube that runs along an endoscope, and has an opening in the vicinity of the endoscope tip, and that is freely deformed so as not to interrupt a surgical operation, and supplies rising water to the nasal cavity.

8. The surgical balloon according to claim 1, which further comprises a movable nose water-supplying tube that is secured to an endoscope in a fixed manner in the major-axis direction of the endoscope and in a manner so as to move within a plane perpendicular to the major axis.

9. The surgical balloon according to claim 1, further comprising a plurality of said shielding balloons.
