The instrument and active cord need to be checked for cracks and/or damages on its insulation.
Polypectomy snares are composed by a catheter and should never be manipulated with its catheter winded as this may damage the device and make its usage impossible!
Make sure to have on hand a grasping forceps in case the snare get stuck in the tissue and needs to be removed by other means.
The surgery room should contain non flammable substances.
After the device is connected with the equipment, the cutting wire cannot touch any other equipment. Spark discharge may cause clinician burns.
When using an electrocardiograph or other physiological monitoring equipment simultaneously with the device on a patient, any monitoring equipment should be placed as far away as possible from the electrodes used with the device. Needle monitoring electrodes should not be used, as they may cause patient burns.
Disposable polypectomy snares successfully pass radiated disturbance electrical testing. When the device is operating with the HF generator delivering HF current, electromagnetic interferences can occur when the HF- generators are used in proximity of diagnostic or monitoring equipment leading to potential inappropriate assessment of the intraoperative state of the patient.
When using the device in the vicinity of the heart, be sure to use it with the minimum necessary output. Spark discharge during operation may affect the heart.
The device when applied to a patient with an implantable pacemaker or any active implantable device may cause malfunction or failure of the pacemaker or the active implantable device, seriously affecting the patient. Before proceeding, always confirm with a cardiologist or the manufacturer of the pacemaker or the active implantable device that it is safe.
If the patient required the use of an external defibrillator during the procedure involving the Disposable Polypectomy Snares, it must be totally removed or disconnected from the HF surgical generator before delivering the electrical shock.
Do not operate the device if the entire length of the surgical accessories is exceeding the maximum permissible length defined for the HF surgical generator to be used
Before to operate the HF surgical generator, verify that all the electrical connections have been properly established and no visible metallic parts are accessible on the snare’s handle avoiding contact with wet tissues.
The snare is a surgery accessory intended to deliver high-frequency electrical power to the body tissue thanks to the embedded electrical wire. Due to the very low electrical resistance, the snare is not dissipating heat. It’s a media to deliver the energy to the interface between the tip of the snare and the body tissues to be treated. The significant electrical resistant of the body tissues to be treated (in contact with the tip of the snare) induce heat to the tissues. During the short duration of power delivery by the HF generator, electromagnetic interferences can occur which could affect diagnostic or monitoring equipment leading to inappropriate assessment of the intraoperative state of the patient. Such potential interferences are inherent to the use of HF surgical generator in combination with surgery tool such as the snare.
The snare must be used with HF cord, HF generator and grounding pad that shall be CE marked and compliant with the electrical safety standards (IEC 60601), to ensure patient safety.
