  • Patent number: 10499940
    Abstract: Disclosed is a lithagogue equipment in vitro, comprising a vibrating bed (10) and a control device (20) located externally, wherein said vibrating bed (10) includes a primary oscillator (111) located above a bed body (102) and connected therewith via an adjustable mechanical arm (108) and a sub oscillator (107) protruding from an upper surface of the bed body (120), wherein said control device (20) is used for controlling the vibration of the primary oscillator (111) and the sub oscillator (107) and the movement of the bed body (102). Said control device (20) and said vibrating bed (10) are separated from each other, and a display (201) is arranged on the control device (20). Accordingly, medical personnel are able to timely adjust the vibrating bed (10), the primary oscillator (111) and the sub vibrator (107) based on the calculus condition displayed via the display (201), greatly improving the operational efficiency.

  • Patent number: 10213095
    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 The inner sheath is connected to main tube, together building a channel via which the endoscope is inserted and withdrawn.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.
