3. It is necessary to loosen and adjust the position of the
probe so that the transceiver window is at the front and
the reference mark is at zero angular level. After
securing the cuff of the probe manipulator, the probe
must be secured in this position.
4. Next, it is necessary to loosen the central handle of the
probe manipulator and carefully insert the probe tip into
the patient's rectum.
5. When the probe is positioned accurately and satisfactory
preliminary visualization is achieved, the bracket of the
multifunctional probe is rigidly fixed to prevent the
focus of the ablation zone from shifting, after which,
under visual ultrasound guidance in real time, the
prostate is conditionally divided into 3 treatment zones

The Sonachill ™ Cooler is a special device designed to
circulate degassed water through a probe and to cool the
rectal wall and HIFU transceiver. The Sonachill ™ chiller is
connected to the back of the Sonablate® 500 system with a
detachable cable. This connection provides power to the
Sonachill ™ chiller and temperature feedback to the system.
The three main components of the Sonachill ™ device are:
active cooling unit (liquid-air cooler);
hose pump;
water tank.
The built-in Sonachill ™ degasser is capable of permanently
degassing the water in the water circuit, making it
unnecessary to use degassed water when first filling the
system. The Sonachill ™ is connected to the probe with
connecting tubing. The Sonachill ™ also has another critical
function: removing any air bubbles from the closed system
before starting the procedure. The water tank has a
connector on the side wall that is connected to the syringe.
This is done in order to change the level of the canister,
increasing and decreasing the pressure in the canister by,
respectively, pumping water or removing it.
