ABSTRACT:
An aqua-stream and aspirator for crushing and removing brain tumors in cerbral surgery comprises a pressure chamber, a soft bottle filled with a sterilized saline solution and mounted within the pressure chamber, an irrigation tube connected at one end to an outlet of the soft bottle, an ejection needle removably connected to the other end of the irrigation tube via a swtich for controlling passage of the solution through the irrigation tube, and a suction tube extending parallel to the ejection needle. The pressure chamber is adapted to be pressurized with a harmless gas so as to compress the soft bottle to eject the solution in the soft bottle from the ejection needle. The ejection needle has a nozzle which is bent in such a manner that the solution ejected from the nozzle is directed toward a confronting inside wall of the tip of the suction tube.
