Operation manual
Patient plate burns often occurs in electrosurgery operation, the operators must grasp
proper sticking method to avoid burning accidents. The unit can use hard patient
plate, single soft patient plate and dual soft patient plate, the usage of which has been
described in “Patient plate using” chapter. The following is some supplement
contents.
A．When fixing the hard patient plate, do not bend it. It may decrease the
contacting are.
B．Do not use the single soft patient plate many times; otherwise the disabled
patient plate may cause burns.
C．We recommend you to use the dual soft patient plate for the contact area can be
monitored successively by the circuit-electrode monitoring system. When the
contact area becomes too small, the unit will stop working and cut off the power
output. Meantime the alarm will be activated. Thus, dual patient plate is much
safer than the single one.
D．Besides ensuring that the plate is close and evenly contacted to the patient’s
skin, the following must be abided:
a. The patient plate should be placed close to the operating part as much as
possible. By decreasing the output impedance, the unit output power will
too be decreased which can reduce the possibility of burns. If the patient
plate is far away from the electrode, the area of high frequency current
channel will be enlarged, so that more parts of the body will be placed in
strong electromagnetic field and high electric potential, increasing the
risk of burns not caused by patient plate.
b. To maintain a large contact area in operation, the patient plate should be
placed on the clear, dry muscle part without any protrusion. Compared to
the fat, muscle has lower impedance and better conducting ability. The
protrusive part may not ensure the adequate contact area and have
influence on the uniformity of the contact area, causing large current
density and increasing the risk of burning.
● Precaution of burns not caused by patient plate
A. The burns not caused by the patient plate included this situation that though the
patient plate is in good condition that suitable for operation, the possibility of
patient burns still exists.
B. The main reason is that several parts on the patient body come in contact with
the ground.
For example: a. The patient’s body may have more than two points touching
the iron bed which is placed on the cement ground;
