Abstract
The invention discloses a percutaneous puncture and dilation visible irrigation-suction system and a method of using the same. The system comprises a main tube, which is contiguous with the sheath tube and has an end for an endoscope insertion. The sheath tube comprises an inner sheath and an outer sheath joined together in a sleeve type. There is a space between inner and outer sheath. The inner sheath is connected to main tube, together building a channel via which the endoscope is inserted and withdrawn. The sheath tube is connected to main tube after completing puncture and dilation, then endoscope system is introduced for observation and operation. The present invention provides a percutaneous puncture and dilation visible irrigation-suction system and a method of using the same, with a continuous controllable visible negative pressure aspirator, achieving high irrigation and powerful suction efficiency, as well as clear endoscopic view.
