For reaching above purpose, the technical scheme that this utility model adopted is: this pulsed sinus cavities is flushing and aspirator continuously, by syringe pipe, suction tube, the flushing liquor control valve, the aspirated liquid control valve constitutes, on the top, end of syringe pipe and sidewall, establish flushing hole, the seat end of syringe pipe connects the flushing sebific duct, it is characterized in that syringe pipe is enclosed within the suction tube, between the outer wall of the inwall of suction tube and syringe pipe is suction chamber, upper end at the flushing sebific duct connects the flushing liquor transfusion bottle, by gravity flushing liquor is injected in sinus cavities, fixing micromachine and fixation clip on the support, establish eccentric on the main shaft of micromachine, the syringe pipe that stretches out from the flushing liquor transfusion bottle passes between eccentric and the fixation clip, by eccentric and fixation clip the flushing sebific duct is clocklike pushed realization pulsed pressure transfusion, thereby make flushing liquor realize pulsed injection flushing; Connect suction hose on the distolateral wall of seat of suction tube, suction hose outer termination gravity aspirator is constantly extracted the liquid that washed in the sinus cavities out by the gravity aspirator.This utility model is also implemented by following measure: described syringe pipe can be made of stainless steel tube or rigid plastics, the overall diameter 2-5mm of syringe pipe, interior diameter 1-4mm, suction tube can be made of plastic tube, the interior diameter of suction tube gets final product than the big 1-2mm of overall diameter of syringe pipe, overlap tightening seal between the seat end mouth of pipe of suction tube and the syringe pipe outer wall, on the flushing sebific duct, establish the flushing liquor control valve, to regulate the feed liquor amount, on suction hose, establish the aspirated liquid control valve, by the adjusting of these two valves, may command feed liquor amount how much, the suction liquid measure how much, or the feed liquor amount is consistent with aspiration; Described gravity aspirator comprises that cylindrical shell, piston, piston rod, weight constitute, piston is contained in the cylindrical shell, the piston rod upper end connects piston, the fixing weight of going up in lower end by the pulling of weight, makes the intravital top of tube form negative pressure, liquid in the suction tube is aspirated, cylindrical shell is fixed on the support, also establishes the soiling solution effuser on the lower sides of cylindrical shell, and the soiling solution effuser is connected with storage soiling solution bottle by sebific duct; On the outer wall of flushing liquor transfusion bottle and cylindrical shell, be equipped with scale, so that in time observe feed liquor amount and suction liquid measure.

The beneficial effects of the utility model are: compare with present use sinus cavities flushing utensil, integrate flushing and aspirate, can realize flushing continuously and suction, flushing and extracting force are all controlled conveniently, and easy what of controlled quentity controlled variable, and easy to operate, patient's misery is little.
