Thermal Effects On Tissue Treated With Loop Electrodes; Electrosurgical Precautions - Cooper Surgical LEEP System 1000 KH1000A Manual De Funcionamiento

REMEMBER, THIS IS NOT AN ATTEMPT TO TEACH ELECTROSURGICAL TECHNIQUE.
The practitioner who lacks experience should not attempt the procedures described below based solely
on this information; instead, the skills required should be acquired in the time-honored preceptor manner.
Call CooperSurgical for information on courses that offer instruction on the proper use of electrosurgical
generators and accessories.
NOTE: The best initial effect is accomplished with the cutting wire in only light contact with tissue. Tight
pressure may cause desiccation of the tissue and will delay the start of the cutting effect.
If the use of other output modes is anticipated, repeat steps in Sections 6.1.3, 6.1.4 and 6.2 as desired.
The output power level settings selected for each output mode will be retained as long as the Electrosurgical
Generator remains ON.
The initial use of any electrosurgical generator always involves some degree of "trial and error".
This is true even when only changing from numbered dials to digital display models within the
same manufacturer's product line. As with any other therapeutic device, it is very helpful to
experiment IN VITRO or on animal sample tissue before using any electrosurgical generator
or methods which are not familiar.
The microprocessor control system of the Electrosurgical Generator was developed specifically
to provide the best possible performance for loop electrosurgical excision procedures. By
exhibiting patience and following the guidelines offered, the practitioner should easily
become familiar with the performance characteristics of the LEEP System 1000
Electrosurgical Generator.

6.3 Thermal Effects on Tissue Treated with Loop Electrodes

Thermal effects on tissue specimens may include:
1) Thermal coagulation injury of the cervix, up to one-third the thickness of normal epithelium of the cervix;
2) Fragmentation of squamous epithelium of the cervix attributable to long exposure periods along the
excision site that allows heat to dissipate laterally;
3) Partial coagulation of the endocervical epithelium because of lateral radiation of heat. Therefore, the Loop
Electrosurgical Excision Procedure (LEEP) may produce thermal effects at the periphery of the excised
tissue and may make histopathologic interpretation difficult or impossible and therefore, may not allow
accurate diagnosis and may obscure the need for further treatment.
Section 7

Electrosurgical Precautions

The safety and effectiveness of electrosurgery is dependent, to a large degree, upon the skill of the
user/operator. It is important that the user/operator read, understand and follow the operating instructions
supplied with the CooperSurgical LEEP System 1000
the principles and use of radio-frequency (RF) electrosurgical systems.
WARNING: Electrosurgery uses radio-frequency energy to cut and coagulate tissue. Because of the
sparking and heat associated with electrosurgery, do not use with flammable anesthetics or other
flammable gases, near flammable fluids or objects, or with oxidizing agents.
•
DO NOT use electrosurgery in the presence of flammable gases, flammable liquids or flammable
objects in oxygen-enriched atmospheres, in nitrous oxide (N
other oxidizing agents.
•
Prevent accumulation of oxygen, nitrous oxide (N
within the area where electrosurgery is performed; moreover, avoid such accumulation in cases of
thorax or head operations unless safely aspirated.
•
Verify that all oxygen connections are leak-free before and during the use of electrosurgery.
•
DO NOT use electrosurgery in the presence of naturally occurring flammable gases which may
accumulate in body cavities such as the bowel.
