SYSTEM for the renovation of the pleural cavity and pleural biopsy

摘要

The invention relates to medical engineering, in particular to a device allowing to remove from the walls, chop and aspirated from the pleural cavity and cavities abscess or phlegmon, abdominal subdiaphragmatic space, bladder and other human body closed cavities pathological accumulation of coagulated blood, detritus, pyogenic capsule contents inherent and parasitic cysts. The purpose of the utility model is to increase efficiency and reduce traumatic oral rehabilitation. The system comprises a double-lumen metal tube with a curved distal end with a double locking mechanism, the elastic tube for fluid supply and for active aspiration actuator in the form of an impeller-cutter disposed in the tip housing. The positive effect of this system is that through a minimally invasive access (torakoport) quickly and conveniently carried out thorough cleansing cavity. This does not create the risk of excessively deep cavity wall damage, bleeding, and create bronchial fistula. Changing the magnitude of the positive and negative pressure in the lumens of the metal tube leads to the sanitation process controlled and regulated in accordance with the rapidly changing needs, to achieve the effect of self-cleaning of the tip of the impeller and the cutter, the tissue fragments, can improve efficiency and reduce the treatment time.
