SPECIFICATION: Some
types of cancer can be successfully treated by heating the
tumor tissue above normal body temperatures. The cancer
cells are usually more susceptible to damage than normal
body cells and so are preferentially killed. Treatment
duration and temperature are important. Heating for about 1
hour at 43º C (about 109º F) appears to have the same
beneficial effect on some tumors as does heating for 30
seconds at 50º C (122º F).
This instrument employs a
Localized Current Field (L C F) generating a two-megahertz
radio frequency, to precisely heat tissue around the probes.
The principle of LCF is passage of RF electric current
between two electrodes. The amount of tumor between the
electrodes increases the resistance component of the
current, causing thermal energy dissipation. Heat is
generated within the tissue and is not the result of thermal
conduction from the electrodes. Temperature is determined by
a thermistor located within one of the electrodes, which in
turn results in modulation of the output power level of the
RF generator to maintain temperature. The instrument reaches
and maintains a temperature of up to 50º C (122º F),
penetrating approximately 3-5mm. This temperature has been
found to alter the nature of cancerous tissue, with minimal
damage to surrounding normal tissue, provoking the
animal’s own defensive mechanisms to cause the tumor to
recede and disappear. This approach to cancer treatment is
not necessarily new, but never before has the equipment been
available economically to the veterinary field.
The instrument is designed
as a rugged, portable field model. Temperature for treatment
is factory set at 50° C and may not be changed. The three
position switch changes only the power and not the
temperature. The circuitry of the instrument is designed so
that heating will not take place unless the probes are in
contact with tissue (or other conductive material) and the
switch is in either "Hi" or "Lo"
position. When these two conditions are met a high frequency
steady tone will be heard from the instrument panel. This
indicates that heating is taking place. It may be necessary
to apply a small amount of physiological saline solution to
the area of treatment. This is necessary when tumors are
somewhat dry and therefore non-conducting.
Battery as supplied is
fully charged. A fully charged battery may be expected to
provide approximately 60 treatments. Replacement gel-cells
may be obtained from Western
Instrument Company.
Batteries should be recharged as soon as possible after use
and not stored in a discharged condition. All parts should
be kept clean and dry. Do not use this model with any AC to
DC power converter. The internal circuitry of the unit
generates considerable heat. The all aluminum-cast handle is
designed as a heat-sink to dissipate heat from the internal
circuitry. This is normal, but should not be uncomfortable
to the user’s hand. In extended use, a glove may be worn
for operator comfort.
EYE SPOON (Included)
For use in treatment of Bovine Cancer Eye. The spoon will
immobilize the eyeball and enable rotation of the eyeball
for accessible tumor exposure.
OBJECTIVE: This
treatment has proven useful for eye tumors in cattle and
horses, warts, sarcoids in horses, anal tumors in dogs,
ringworm, dermalogical conditions in horses, dogs, and cats.
Consult published literature for detailed usages and
procedures before using these instruments.
NOTE: Technical paper
on the use of L.F.C. Megatherm is available from Western
Instrument Company
For veterinary use only - should be
used by or under the direction of a veterinarian. |
