**DEVICE DESCRIPTION:** The monopolar electrosurgical device consists of an electrically conducting cannula which has plastic electrical insulation on its exterior surface. This cannula fits into a plastic handle that has a central axial passage in line with the suction hole of the cannula. This suction hole leads to a suction hose fitting molded into the aft end of the handle. During use a hose connected to an external suction source is connected to the handle's suction fitting to provide suction to the cannula. A bleed hole in the handle allows the surgeon to control the amount of suction with his fingertip. High frequency power is supplied to the device through a 10 foot long power cord which enters the aft end of the handle and is internally connected to the cannula and switching circuitry. The distal end of the power cord has a standard plug that fits into most electrosurgical generators that have the accessory fingertip control option. The surgeon activates the cautery tip by pressing a push button located near the suction bleed hole.

The new device will be marketed in cannula french size 10 with a 6 inch length

**INTENDED USE:** For use with electrosurgical generators that have the accessory fingertip activation feature to control bleeding through the use of suction and cautery.

## SAFETY AND EFFECTIVENESS STATEMENT FOR ELECTROSURGICAL DEVICES

The effectiveness and safety of electrosurgery as a cutting and coagulation method is extensively documented and well known. The hazards of electrosurgery are similarly well known and documented. The attached bibliography provides in depth information regarding the safety, effectiveness and hazards of electrosurgery.

Generally the hazards can be identified as patient /user burns or electrical interference with an electric device such an implanted pacemaker. In addition, as electrosurgery creates a spark, flammable gases or materials could ignite.

Overwhelmingly, the majority of burns are a result of a ground fault in the patient/dispersive electrode/generator return current pathway. As the current finds an alternate path to ground (through the table, ECG lead, towel clip, etc.), it concentrates at this area causing a burn. the severity of the burn depends upon the time of exposure to the current. Improper attachment of

# 510(K) SUMMARY

the dispersive electrode to the patient is the most common cause of ground fault burns. Additionally, these types of burns can also occur from a defective return circuit in the generator, a defective dispersive electrode, or user error in the system set up. The subject product of this 510(K) notification can not contribute to ground fault type burns.

Less frequently, burns occur as a result of an activated active electrode contacting electrically conductive instruments of equipment. In these cases, the electrosurgical effect is transmitted along the conductive pathway to unintended locations. Even though the active electrode is involved in these instances, contact with the instruments or equipment is required. This contact occurs accidentally by the user and is not device related.

The current interference with electronic equipment occurs when the dispersive electrode is positioned in such a way that the current pathway through the patient crosses over the equipment. Placing the dispersive electrode in a location which prevents the current flow from crossing over the electronic equipment will avoid the interference. the dispersive electrode placement is totally user dependent and unrelated to the subject device.

Specific hazards associated with the subject 510(K) device would involve insufficient materials and design to safely carry the current without leakage or switch anomalies could cause unintended activation of the current. However, as electrosurgery is so common, an industry standard has been developed to ensure the safety of all components of a electrosurgical system. This Standard, ANSI/AAMI HF18-1993 defines the parameters, tests and requirements needed to assure the safety of electrosurgical system components. The subject device of this 510(K) notification meets all applicable requirements of this standard.
