Cryo-S classic vacuum apparatus is intended for local, rapid and efficient freezing of tissues using a wide range of contact cryoapplicators and unique spraying cryoapplicator, which with continuous cooling adjustment permits freezing of very small lesions (several cubic millimetres) as well as very large ones (several dozens cubic centimetres) by directly spraying liquid nitrous oxide on treated lesion.

All-in-One deviceused in Proctology with built-in suction nozzle and a ligator for placing rubber rings on haemorrhoidal varices.


Use of Cryo S classic with vacuum in Proctology

Rubber Banding : This technique is widely used for hemorrhoids protruding into the anal canal. Rubber band ligation can be performed in a doctor's office and requires little preparation. Often, however, there is the need for more than one procedure to resolve patient's condition. Rubber band ligation is most effective when combined with  cryosurgery.

Metrum CryoFlex recommend purchasing the cryoprobe P-10 which perfectly works with our device.The cryoprobe P-10 easily and effectively eliminate haemorrhoids using freezing method. Additionally, cryoprobes P-10 are used to freeze haemorrhoids already obliterated with the use of haemorrhoidal rings. After such procedure haemorrhoids are destructed faster.

Super Freezing
 - our Cryo-S classic device uses N2O/CO2 to super freeze the hemorrhoid. This causes the affected tissue to slough off, so that new healthy tissue can grow in its place. This technique is most effective when it is used on internal and external hemorrhoids.


Technical specification

  • Device has built-in vacuum generator
  • No electricity use
  • Uses built-in battery
  • Pneumatic supply system(gas cylinder)
  • Cooling medium: Nitrous suboxide(N2O),or Carbon dioxide(CO2)
    • Efficient and easy in application and safe in storage(used steel cylinders).10L of the gas is capable to serve approximately 60-70 patients. The gas provides us with low temperatures down to – 89C by expanding in the cryoapplicators’s.
  • Gas flow control and adjustment(ONLY CRYO-S Devices)
    • Key parameter defining cryoapplicator’s efficiency. The volume of gas flowing through the cryoapplicator is measured by the flow meter. Flow volume indicates condition of the cryoprobe of the device. Optimal value of the flow means that freezing procedure will be performed effectively. Flow value control on the indicator and flow of the gas from device’s outlet is very important in maintenance of the procedure efficiency. Small values on the flow indicator means that cryoprobe is partly closed(i.e. with dirt or moisture) or pressure in cylinder is too low.
  • Pressure gauge and pressure adjustment
    • After the cylinder valve is opened, internal circuit of the apparatus is filled with gas under pressure: yellow 0 – 20 bar: end-piece cleaning  pressure / blue 25 – 50 bar: standard operating pressure / red 60 – 80 bar: overpressure
  • Timer setting
    • Procedure duration measurement
    • Pre-set procedure duration indication with beeps
    • Device informs user about the time flow every 5 seconds with beep or voice signal
