SurgiStat Low-Power Electrosurgical Generator Service Manual
Safety Precautions When Testing the Generator
Do not wrap the accessory cords or patient return electrode cords around metal objects. This may
induce currents that could lead to shocks, fires, or injury to the patient or surgical team.
Failure of the high-frequency surgical equipment could result in an unintended increase of output
power.
Use the lowest output setting necessary to achieve the desired surgical effect. Use the active
electrode only for the minimum time necessary in order to lessen the possibility of unintended burn
injury. Pediatric applications and/or procedures performed on small anatomic structures may
require reduced power settings. The higher the current flow, and the longer the current is applied,
the greater the possibility of unintended thermal damage to tissue, especially during use on small
structures.
Avoid using power settings that would exceed the highest maximum voltage that is acceptable for
each accessory. Choose only accessories that will withstand each mode and power setting.
Use electrosurgery with caution in the presence of internal or external devices such as pacemakers
or pulse generators. Interference produced by the use of electrosurgical devices can cause devices
such as pacemakers to enter an asynchronous mode or can block the pacemaker effect entirely.
Consult the device manufacturer or hospital Cardiology Department for further information when
use of electrosurgical appliances is planned for patients with cardiac pacemakers or other
implantable devices.
In some circumstances, potential exists for alternate site burns at points of skin contact (e.g.,
between the arm and the side of the body). This occurs when electrosurgical current seeks a path
to the patient return electrode that includes the skin-to-skin contact point.
Current passing through small skin-to-skin contact points is concentrated and may cause a burn.
This is true for grounded, ground referenced, and isolated output generators.
Precaution
Do not stack equipment on top of the generator or place the generator on top of electrical
equipment. These configurations are unstable and/or do not allow adequate cooling.
Provide as much distance as possible between the electrosurgical generator and other electronic
equipment (such as monitors). An activated electrosurgical generator may cause electrical
interference with them.
Do not turn the activation tone down to an inaudible level. The activation tone alerts the surgical
team when an accessory is active.
At no time should you touch the active electrode or bipolar forceps. A burn could result.
Non-function of the generator may cause interruption of surgery. A backup generator should be
available for use.
When using a smoke evacuator in conjunction with the electrosurgical generator, place the smoke
evacuator a distance from the generator and set the generator volume control at a level that
ensures that the activation tones can be heard.
