Apparatus for removing calculus in vitro

A lithagogue equipment in vitro, characteristics in that, said lithagogue equipment comprises a vibrating bed and a control device provided outside the vibrating bed;

• said vibrating bed includes a primary oscillator located above a bed body and connected with said bed body via an adjustable mechanical arm, and a sub oscillator protruding from an upper surface of said bed body, said control device is used to control the vibration of the primary oscillator and the sub oscillator and the movement of the bed body,
• wherein a length of the sub oscillator is in a range of 200-300 mm, and a height of the sub oscillator from an upper surface of the bed body is adjustable in a range of 20-50 mm such that the sub oscillator is configured to be attached to a treatment area in a waist region of a patient,
• wherein the primary oscillator and the sub oscillator are configured to remove a renal calculus with a vibrating frequency of 50 Hz or less,
• wherein said lithagogue equipment further comprises a scanning imaging device which is provided above said bed body and adjustably combined with the bed body, said control device includes a displaying device and a work station, the work station transfers images scanned by the scanning imaging device to the displaying device, and
• wherein a pressure sensor is provided inside of the primary oscillator, the pressure value applied by the primary oscillator is displayed by the displaying device of the control device.
