Nasal sinus flushing drug administration device

Abstract

The invention relates to a nasal sinus flushing drug administration device. The device comprises a nasal vestibule plug and a sinus flushing drug administration tube, the nasal vestibule plug comprises a nasal vestibule plug and a handle, the nasal vestibule plug has the same shape as the nasal vestibule space and is connected to the handle, and a hollow sinus guiding tube used for guiding the sinus flushing drug administration tube is arranged in the middle of the plug. The nasal sinus flushing drug administration device is prepared by following steps: patient's nasal sinus thin-layer CT scanning, computer three-dimensional reconstruction of a nasal cavity and a nasal sinus space, designing of the a nasal vestibule plug with the same shape as the nasal vestibule, wherein the hollow nasalsinus guide tube is arranged in the middle of the plug and just allows the nasal sinus flushing drug administration tube to pass through. The extension projection part of the drug administration tubestill travels on the reconstructed nasal cavity and nasal sinus space, and is not contacted with the side wall. The extension length and the opening mode of the tube are determined by the nasal cavityand nasal sinus space and the required treatment part, and the limited extension protection is performed before use, so that the flushing drug administration tube can accurately and noninvasively reach the nasal sinus position required for treatment, and local accurate flushing and drug administration treatment are realized. The device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to the treatment of local repeatable, accurate and non-invasive irrigation and administration after sinus surgery, and is a local irrigation and drug delivery device for sinuses and its use method. Background technique [0002] Chronic rhinosinusitis and nasal polyps are common and frequently-occurring diseases in clinical practice, accounting for about 12% of the natural population. Although in recent years, with the understanding of this type of disease and the progress of nasal endoscopic surgery, the curative effect has been greatly improved, but nearly 50% of the patients are still difficult to obtain satisfactory results with any treatment. Especially for eosinophilic nasal polyps, the postoperative recurrence rate is extremely high, close to 100%. Reoperation or multiple operations are still difficult to cure, and such patients with a high recurrence rate are more ...

AI Technical Summary

Problems solved by technology

Reoperation or multiple operations are still difficult to cure, and such patients with a high recurrence rate are more sensitive to glucocorticoid therapy, and the curative effect is better, but long-term application of the whole body may cause serious complications; The space is narrow, irregular, and far away from the anterior nostrils. The existing nasal spray glucocorticoids cannot directly reach the diseased sinuses. It is very painful, and the patient's compliance is poor, so the treatment effect is poor
