The invention provides a sacculus
medicine-spraying device for treating nasosinusitis or allergic rhinitis. The sacculus
medicine-spraying device comprises an
inflatable sacculus, a sacculus inner
pipe and a sacculus
catheter, wherein the sacculus inner
pipe penetrates through the sacculus and extends axially; and the far-end opening of the sacculus
catheter is ended in the sacculus. The sacculus
medicine-spraying device provided by the invention has the advantages that the prepared effective treating medicine liquid or gelatinous or powdery
solid particles can be conveyed to the diseased part of the paranasal sinus, and the cavity part of the frontal sinus and / or the
maxillary sinus is used as a medicine storage device, so that the diseased part can be treated by medicines in enough-long
treatment period. The sacculus medicine-spraying device also has the advantages that effective medicines are uniformly sprayed to the diseased part by minimally
invasive surgery; the medicines stored on the frontal sinus and the
maxillary sinus can be conveyed to the diseased part continuously in time along with the swinging of the
cilium of the
nasal cavity and the flowing of
mucus of the
nasal cavity; and before the stored medicines are metabolized, the medicines can be directly and continuously fed to the diseased part, and the treating effect of common medicine feeding is greatly improved.
