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

Apparatus for removing calculus in vitro

A device for removing a stone, a stone fragment, or a foreign body from a patient comprising a suction evacuation assembly which includes a primary sheath with a flexible end, an obturator releaseably secured to the sheath, a side arm emanating from the primary sheath, a deflection mechanism which is operationally associated with the flexible end of the sheath and a secondary sheath with a dual lumen and an oblong shape wherein the dual lumen allow passage of surgical instruments and irrigation fluid and wherein the oblong shape provides for adequate space for the egress of stone fragments and fluid through the primary and/or secondary sheath, wherein the obturator is withdrawn from the primary sheath and the secondary sheath is inserted into the primary sheath and into the patient in order to facilitate the removal of the stone, stone fragment or foreign body.
