Nortech AUTOLITH IEHL Quick Reference And Information Manual

The AUTOLITH System
Quick Reference and Information Guide

Getting STARTED

Turn on the power “ON” switch after plugging the AUTOLITH® System into a

proper power outlet. Attach the foot-pedal to the front panel foot-pedal port and
place the sterilized EHL Probe and Extender Cable onto the sterile field using
proper sterile technique.

Connecting the EHL Probe

Connect the EHL probe to the end of the extender cable opposite
the square black ferrite. Pass the remaining end of the extender
cable to the O.R. circulator.

EHL Probe Recognition

The O.R. circulating nurse should then connect the remaining end of the

extender cable to the front panel “PROBE” port. Notice the “Connect

Probe” message change to indicate the size of the EHL probe that has

been connected, i.e. 1.9Fr. (.63mm). The AUTOLITH® System will now
deliver the precise amount of energy specific to the size of the
connected EHL probe.

The Endoscope and EHL Probe

The doctor should now prepare to fragment the stone. Careful insertion of the EHL probe into the
appropriate endoscope working channel is now accomplished and treatment of the stone is ready
to start. Using direct visualization, the EHL probe tip and the stone are sighted. Normal
physiological SALINE (premixed bags of .9% normal saline) should be used for irrigation at all
times.

Power

Start LOW and increase the power if needed for
effective stone fragmentation.

The total power range is 10% to 100%

Suggested to start: 30%-40% Power

The OUTPUT light will flash every time a shot has been triggered.

Note:

• Using higher power settings and a higher number of shots
may reduce probe life.

• The most effective stone fragmentation occurs with the end
of the EHL probe 1-2mm from the stones surface.

• Press the Standby button to avoid
unintentional probe firings. This feature is
useful if the scope and EHL probe are brought
outside of the body.

• Press Total Shots to see how many shots
have been discharged.

Frequency of Shots

This adjusts how fast the selected number of shots are
delivered. For stones that are free to move or bounce
away, select fewer shots at a higher frequency. A rate
of 30 shots per second is the highest (fast) frequency
setting. A rate of 1 shot per second is the slowest

frequency setting. Suggested setting: 30/sec.

Number of Shots

Again, if the stone can move or bounce away, select
fewer shots. A maximum of 60 shots delivered over 2
seconds is the maximum number of shots that can be
fired with 1 foot-pedal depression.

Suggested setting: 3-5 shots per foot-pedal
depression.

Keeping the probe tip 1-2mm
from the stone surface is ideal.
