Instruments for electrosurgery must only be used by persons who have been specially trained or instructed in this. Contraindications - Do not use the instrument if, in the opinion of the attending physician, the risks to the patient outweigh the benefits. Incidents that have been reported in connection with the use of electrosurgical systems - Unintended activation with resulting tissue injury in the wrong location and/or damage to the equipment. - Fire in connection with surgical drapes and other inflammable materials. - Alternating current paths leading to burns on spots where the patient or user comes into contact with components without insulation. - Explosions caused by sparks in the proximity of inflammable gases. - Perforation of organs. Sudden severe bleedings. Use and safety instructions Non-observance of these use and safety instructions may lead to injuries, malfunctions or other unexpected incidents. - When using electrosurgery in patients with pacemakers or other active implants, special requirements apply (e.g. low HF-current, patient monitoring). In any case, a cardiologist or appropriate medical specialist must be consulted. - Before initial use and any further use, all instruments must be completely cleaned, disinfected and sterilised and their function must be checked. - It is very important to check every surgical instrument for visible damage and wear, such as cracks, breaks or insulation defects before each use. In particular areas such as blades, tips, notches, locking and blocking devices, as well as all movable parts, insulations and ceramic elements must be checked carefully. - Never use any damaged instruments. - Never use the instruments in the presence of flammable or explosive substances.  - When temporarily not in use, the instrument must be placed electrically insulated from the patient. - Activate electrosurgical current only if the contact areas are in full view and have good contact with the tissue that needs to be treated. Do not touch any other metallic instruments, trocar sleeves, optics or similar objects during use. - Observe the use and safety instructions of the manufacturer of the high-frequency surgical device. Applies for monopolar mode of operation: Ensure correct application of the neutral electrode on the patient; otherwise, there is a danger of burns. Assembly For assembly and disassembly of the instrument follow the pictogram, which is available upon request, or can be downloaded on Special instructions for the hysterectomy loop electrode - Insert the instrument through the cannula with the loop pulled inside the shaft. - Thoroughly check correct placement of the loop around the uterus prior to activation of the electrical current; the entire tissue surrounded by the loop will be cut. - After correct placement, maintain tension of the loop to avoid uncontrolled slip of the loop. Maintain some safety distance to the ligature. - During electrosurgical cutting, pull the loop continuously inside the shaft. Cutting will start at the uninsulated part of the loop wire. - The loop wire is a replaceable, sterilisable product for single use that should be replaced following each procedure. Reprocessing Due to the product design, the materials used and the intended purpose, it is not possible to define a limit with regard to the maximum possible number of reprocessing cycles. The serviceable life of the instruments is determined by their function as well as by a careful handling. Instruments for electrosurgery are by their nature subject to increased wear depending on the type and time of use. Preparation and transport Immediately after each use, clean the instruments with a soft brush under cold tap water until all visible contamination is removed. Do not use fixation agents or hot water (>40°C). Storage and transport of the instruments to the reprocessing location must take place in a sealed container. Complex instruments must be taken apart for cleaning and disinfection in accordance with pictogram. Machine reprocessing Cleaning Place the instruments in a basket on the insert module or on the inserts of the MIS module and start the cleaning process. 1. Prerinse with cold water for 1 min 2.
