General Warnings •
Verify that the unit is fully operational prior to administering power output for tissue sealing.
•
This equipment is for use only by qualified medical personnel trained in the use of ultrasonic surgery or electrosurgery. Inappropriate use of the equipment by untrained medical personnel may result in hazardous electrical output.
•
The use of flammable anaesthetics or oxidizing gases such as nitrous oxide (N2O) and oxygen should be avoided if a surgical procedure is carried out in the region of the thorax or the head, unless these agents are sucked away.
•
Do not use in the presence of flammable anesthetics or oxidizing gases such as nitrous oxide (N2O) and oxygen as explosion may occur.
•
Non-flammable agents should be used for cleaning and disinfection wherever possible.
•
Flammable agents used for cleaning or disinfecting, or as solvents of adhesives, should be allowed to evaporate before the application of HF surgery. There is a risk of pooling of flammable solutions under the patient in body depressions such as the umbilicus, and in body cavities such as the vagina. Any fluid pooled in these areas should be mopped up before the electrosurgery. Attention should be called to the danger of ignition of endogenous or other flammable gases. Some materials, for example cotton and gauze, when saturated with oxygen may be ignited by sparks produced in normal use during electrosurgery.
•
Do not operate the Generator G11 in a moist environment as a shock hazard may exist. If liquids have entered the Generator G11 the unit must be returned to the manufacturer for testing prior to use.
•
Do not operate the unit in close proximity to volatile solvents such as methanol or alcohol as explosion may occur.
•
Avoid use of Generator G11 adjacent to or stacked with other equipment. If adjacent or stacked use is necessary, monitor the Generator G11 and the other equipment to assure normal operation.
•
Interference produced by the operation of high-frequency surgical equipment may adversely affect the operation of other electronic medical equipment such as monitors and imaging systems.
•
Check if the patient has a pacemaker or implanted cardioverter/defibrillator. Consult the pacemaker or implanted cardioverter/defibrillator manufacturer for information about the effects of radiofrequency energy on these devices.
•
Use of accessories and cables other than those specified may result in unpredictable performance, increased electromagnetic emissions, or decreased electromagnetic immunity. No customer modification of this equipment is allowed; modification of this equipment could have a negative impact on electrical safety and electromagnetic emissions.
•
No internal user serviceable parts. For service, return the generator to an authorized Ethicon Endo-Surgery service facility.
•
To avoid the risk of electric shock, this equipment must only be connected to a supply main with protective earth.
•
To isolate the Generator G11 from supply mains power, disconnect the power cord either from the back panel of the generator or from the wall. Ensure access to these points are kept clear.

Generator G11
Generator G11 Operator’s Manual •
This device is not MR safe and is not MR compatible.
•
This device seals vessels up to a maximum diameter of 7 mm depending on the instrument used. Refer to the instrument IFU for further information.
•
As with all energy sources (Electrosurgery, Lasers, or Ultrasound) there are concerns about the carcinogenic and infectious potential of the by-products such as tissue smoke plume and aerosols. Appropriate measures such as protective eyewear, filtration masks, and effective smoke evacuation equipment should be used in both open and laparoscopic procedures.
General Cautions •
The touch screen display of the generator is very sensitive. Do not use sharp metal object on the touch screen.
•
Removing bottom screws or opening of this device invalidates the warranty and could create hazardous condition.
•
Read instructions prior to use and follow the hospital’s clinical practice guidelines for ultrasonic surgery, electrosurgery, gynecology and laparoscopic procedures.
•
Replace fuses only with the appropriate type and rating. See System Specifications.
•
Do not sterilize the Generator G11. Sterilization will damage the unit.
•
Do not restrict the openings on the bottom and the back panel of the Generator G11, as they provide the required airflow for cooling.
•
If electromagnetic interference with other equipment is suspected, reorient the device or remove possible sources of interference (for example, cellular phones, radios, etc.) from the room.
•
Monitoring electrodes should be placed as far as possible from the disposable device tips when high frequency surgical equipment and physiological monitoring equipment are used simultaneously. Monitoring systems incorporating high frequency current-limiting devices are recommended for use.
•
Needle monitoring electrodes are not recommended.
•
Activation of a radiofrequency device when not in contact with target tissue or in a position to deliver energy may cause capacitive coupling.
•
The patient should not come in contact with metal parts which are earthed (grounded) or which have appreciable capacitance to earth (for example operating table supports, etc.).
•
Cables to the surgical electrodes should be positioned so that contact with patient or other leads is avoided.
•
CRT11 is recommended if Generator G11 is moved out of the operating room. Maintain control of the generator and cart when moving over thresholds.

Generator G11 Operator’s Manual Chapter 4 - Troubleshooting and Screen Guide General Troubleshooting Informative The user interface for the Generator G11 has a number of informative screens to guide the efficient use of the generator. Informative screens will maintain a consistent dark background to differentiate them from the alarm screens shown below.
Alarm System The Generator G11 includes integrated diagnostics that monitor the operation of the generator and accessories and flash either informative screens or alarms with no delay. In addition to audible alarm sounds, the display of alarms on the front panel is easily observable by the surgeon or nursing staff from the surgical field. All alarms are technical alarms and are based on electrical parameters. There are no physiological alarms that are produced by the Generator G11. Alarm settings are not adjustable by the operator nor can priority be reassigned. Alarm settings also do not adjust to operator inputs nor do they change through power loss. The Power on Self Test (POST) verifies that the generator is operational. Since the alarms are integrated into the software algorithms responsible for running the appropriate instruments, the POST also verifies alarm operation. Therefore, a separate test for verifying the alarm output is not required. During the POST an audio tone is emitted from the generator so the user can verify that the audio output is operational. Visual output can also be verified through the start up screens. Alarm audio cannot be paused but audio automatically ends when the user discontinues activation of the instrument. Alarms and other events are logged in the generator. The log is retained after power is removed and is accessed through the biomed screen. There is no reminder signal.
Audio Sound Pressure Levels •
Power up test audio feedback sound level: 66 - 70 dBA
•
Activation tone sound level: Default 65 - 68 dBA, adjustable to between 55 and 70 dBA
•
Medium level alarms: Greater than 75 dBA (not adjustable)
•
Low level alarms: Within 70 - 75 dBA (not adjustable)
Alarm Definitions The following alarm priorities are used for the Generator G11. All alarms stop generator output and high priority alarms will take precedence over lower priority alarms. Only one alarm will be displayed at a time since any alarm stops output. Low Priority Alarms Requires surgical staff attention for continued, efficient procedural progress. A low priority issue will not generally progress to a hazardous condition even if not addressed promptly but it must be addressed to continue the procedure. The screen shows a solid yellow background with a low priority alarm symbol. A two-tone audio alarm sound accompanies a low priority alarm. Medium Priority Alarms Requires prompt surgical staff attention to reduce or mitigate a hazardous condition. Ignoring this alarm can result in a serious injury or death. The screen shows a solid yellow background with a flashing medium priority alarm symbol. A three-tone audio alarm sound accompanies a medium priority alarm. High Priority Alarms There are no high priority alarm conditions in Generator G11.
