VULCAN™ Generator Operations/Service Manual |
Introduction / Device Description / Indications for Use / Contraindications / Warnings
Introduction
The Smith & Nephew VULCAN™ Generator is designed to provide finely-controlled radiofrequency (RF) energy for the coagulation, cutting, ablation, and hemostasis of soft tissue during a variety of surgical procedures.
The generator control unit is specifically designed for use with Smith & Nephew temperature-controlled and power-controlled probes.
Indications for Use
The Smith & Nephew VULCAN Generator is indicated for general surgical purposes, including orthopedic and arthroscopic applications, for coagulation, ablation, and hemostasis of soft tissues in combination with Smith & Nephew temperaturecontrolled, cutting, and ablation probes.
Device Description
The generator control unit is a line-voltage powered, radiofrequency generator capable of delivering up to 200 watts of power. The generator control unit
includes a neutral electrode monitor (NEM) to monitor split grounding pad contact quality. It is designed to be used only with Smith & Nephew temperaturecontrolled, cutting, and ablation probes and includes the following features:
•Two RF output modes: Temperature Control Mode, where the output power is softwarecontrolled to maintain a specified tissue temperature; and Power Control Mode, used for cutting, ablation, and hemostasis.
•Numerical displays for impedance, set power, delivered power, set temperature, actual temperature, set cut, set coagulation, and preset selections.
•Message display for text messages.
•Indicators for electrode type (monopolar or bipolar), mode (Temperature Control or Power Control), stand-by, RF power on, RF output type (cut or coagulation), fault, and split grounding pad monitoring. NEM monitors the split grounding pad connection during surgery, discontinuing
RF delivery if a fault in the NEM monitor circuit is detected.
•A probe recognition system: the generator control unit automatically selects the appropriate mode and preset settings for the probe type.
The Smith & Nephew VULCAN Generator software can be upgraded at the customer’s location
with a Smith & Nephew supplied PCMCIA card. For information regarding software upgrades, please contact your authorized Smith & Nephew representative.
Contraindications
There are no known absolute contraindications to the use of electrosurgery.
The use of the Smith & Nephew VULCAN Generator and accessories is contraindicated, when, in the judgment of the physician, an electrosurgical procedure would be contrary to the best interest of the patient.
Warnings
•It is the surgeon’s responsibility to be familiar with the appropriate surgical techniques prior to use of this device..
•Read these instructions completely prior to use..
•DANGER: Risk of explosion if used in the presence of flammable anesthetics, skin preparation agents, or biointestinal gases..
•Hazardous electrical output.. This equipment should be used only by qualified medical personnel trained in the use of electrosurgery devices..
•This device has been tested and verified to comply with the IEC 60601-2-2.. This exceeds the requirements specified by FCC part 18 for ISM equipment.. This device is intended for operation in a medical facility only.. Usage in a residential environment will likely cause unacceptable RF interference for which the user is held responsible..
•The generator control unit must be powered from a properly grounded 120–240 VAC, single-phase supply.. Excessive risk (leakage current) may result if this equipment is connected to other than the manufacturer’s recommended power distribution system..
•Risk of burns or fire.. Do not use near conductive materials such as metal bed parts, inner-spring mattresses, etc..
VULCAN™ Generator Operations/Service Manual |
1061526 Rev. C |
Warnings (continued)
•Check that the electrical equipment is properly grounded (i..e.. plugs contain a ground prong).. The generator control unit must be plugged into a hospital-grade AC outlet..
•Safe use of monopolar electrosurgery demands proper grounding of the patient and proper insulation between the patient and any metal surfaces.. A split pad with a surface area of at least 20 square inches (130 cm2) is required.. Valleylab… REM… pads (REF 7209687)
meet this dimensional requirement and are recommended by Smith & Nephew for use with the VULCAN™ Generator.. Pads with a surface area of less than 20 square inches may have a lower dispersive effect.. It is the responsibility of the user to qualify any alternate ground pad..
•Use of an inadequate ground pad or incorrect placement of the ground pad may result in a burn injury to the patient..
•Improper probe usage may result in patient burns at the return pad.. To avoid this, follow the manufacturer’s Instructions for Use..
•Do not exceed the RF duty cycle for the probe..
•Do not withdraw the probe while energy delivery is activated; this may result in an unintended patient burn or ignition of flammable materials..
•When using RF surgical equipment, keep the working part of the RF probe’s active electrode in the field of view to avoid accidental RF burns.. Avoid contact of the probe with metal parts of the scope and other conductive accessories by ensuring, before activation of the RF probe, that the active electrode is at sufficient distance from the tip of the scope..
•Failure of the radiofrequency surgical equipment could result in unintended increase of output power..
•Burns to the surgeon’s hands may be possible if a probe comes into contact with a metal instrument or surface..
•Use of electrosurgery in patients with internal or external pacemakers, implantable defibrillators or monitoring equipment
may require special considerations.. The attending cardiologist and/or the pacemaker manufacturer should be consulted prior to surgery..
•The operating table should be grounded..
•During monopolar electrosurgery the patient should not come into contact with any metal parts which are grounded or which have appreciable capacitance to earth (operating tables, supports, etc..).. The use of anti-static sheeting is recommended for this purpose..
•During monopolar electrosurgery skin-to-skin contact (i..e.., between the arms and body of the patient) should be avoided.. Insertion of dry gauze or its equivalent is recommended..
•The probe cables and extension cable should be positioned in such a way that contact with the patient or other leads is avoided.. Probes not in use should be stored isolated from the patient..
•Incorrect actual temperature readings may result in improper treatment.. Verify that the TEMPERATURE display reads the expected value (room temperature or body temperature) prior to treatment.. If the TEMPERATURE reading is not accurate, check the device and connectors for damage, moisture, or contamination.. Clean or replace as needed..
•If desired tissue effect is not being achieved, do not increase power beyond the normal range without first inspecting the integrity of the probe and neutral (return) electrode..
•To prevent electric shock, unplug the control unit from the electrical outlet before attempting to replace the fuses..
•To avoid fire hazard, use only fuses of the correct type, voltage rating, and current rating..
•To prevent electric shock, do not remove the control unit cover.. There are no userserviceable components inside.. Dismantling the equipment will void the warranty.. Refer servicing to qualified Smith & Nephew personnel..
