provides an excision with average hemostasis effect. Blend 3 provides an excision with maximum
hemostasis effect.
Coagulation of bleeding vessels after completion of an excision is usually accomplished using a
ball electrode in the coagulation mode. In this mode, the ball electrode will throw sparks to the
surface of the tissue with slight separation of the ball from the surface. This process, known as
fulguration coagulation, should be done briefly to stop any bleeding that occurs. It should not be
overdone. Other hemostatic techniques use the ball in contact with the tissue surface to coagu-
late by desiccation with little or no sparking. Desiccation techniques may cause unnecessarily
deep thermal damage if not performed carefully. As with cutting, coagulation should be practiced
on appropriate tissue simulators before performing the procedure on a patient. The coagulation
power required is dependent on many factors such as:
1. Length of time the current is applied. Lower power outputs applied for longer periods produce
a greater depth of coagulation than higher outputs applied for a shorter period of time.
2. Type of electrode used. A ball electrode will require a higher power setting than pointed elec-
trodes, due to the larger area of tissue contact.
3. Character of surrounding media. Higher power outputs are required for coagulation under
water or in a bloody field than for coagulation in relatively dry operative sites.
For typical LETZ procedures, cutting mode output settings ranging from "40" to "70" have been
found to be effective, with a setting of "65" typically used. Coagulation mode output settings
ranging from "40" to "75" have been found to be effective in providing hemostasis for bleeding
vessels, with a setting of "60" typically used.
Operational Safety Notes and Warnings
The system has been designed to implement the best principles of electrical safety. The
remaining burden for patient and operator safety lies with the user of the device. The most
important safety factors that are under control of the operator are delineated below. It is impor-
tant that these points, as well as others made throughout this manual, be read and understood
before performing surgery with this instrument.
Inspection. When the system is unpacked after transport between locations, as well as periodi-
cally with ordinary use, visually inspect the system, accessories, accessory receptacles,
power cord, and power cord receptacle for damage or missing parts. Do not use the system with-
out correcting any observed or suspected damage.
WARNING: No modification of this equipment is allowed. Modification of the
may expose operator and/or patient to hazardous electrical currents.
Dispersive electrode pad . Always apply the dispersive pad as indicated in the dispersive pad
instructions for use. Directions are provided with the dispersive pads. These directions should be
rigorously followed to prepare, apply, maintain, and remove the dispersive electrode, and periodi-
cally make a visual check of the pad application to the patient.
To ensure safe contact of the dispersive pad to the patient, use only pads listed as compatible
with the 's CQM system. The use of contact monitoring pads that are not on the list in
