5.2 Connecting the product
1. Unscrew the protective cap from the probe coupling.
2. Screw the cryoprobe to the cryosurgery unit via the connect-
ing adapter (Art. No. 20416-034).
5.3 Checking function and seal
Perform the check in a well-lit location.
1. Immerse the cryotip to a depth of at least 5 cm in sterile
warm water at a temperature of approx. 20 °C (alternatively:
isotonic NaCl solution).
2. If small bubbles develop during immersion: Diffuse the bub-
bles by briskly moving the cryotip back and forth in the wa-
ter.
3. Activate the freeze function of the cryosurgical unit for ap-
prox. 5 seconds.
A clearly visible, homogenous ball of ice must form at the cryotip
when freezing capacity is sufficient. Gas bubbles must not es-
cape under any circumstances.
Never use a product that is not leak-tight or a product with in-
adequate freezing capacity. There is a risk that a gas embolism
could develop if an application element is used that is not leak-
tight.
5.4 Using the product
Note: To prevent the cryotip from freezing to the inside of the
endoscope, the metal cryotip should be fully extended outside of
the working channel of the endoscope throughout use. The first
black ring must be visible.
