Additional Manufacturer Narrative
(b)(4).Warning! hf cables with defective, brittle or cracked insulation can cause burns to the user or patient.If the electrical line breaks, an arc can occur causing burns to the user or patient or start a fire, regardless of whether the insulation is also damaged or not.Never use or repair defective hf cables! always replace them.Do not modify hf cables! the uni/monopolar cables may be operated at a maximum recurrent peak voltage of 4000 vp and the bipolar cables at max.1000 vp.Important! when plugging and unplugging the hf cable, always hold the plug, never pull the hf cable.Do not place hf cables in parallel with other signal lines (e.G.Camera cable) to minimize the danger of interference from hf radiation.Richard wolf medical instruments corporation (rwmic) considers this case closed.In the event that rwmic receives additional information a follow up report will be submitted to the fda.
Event or Problem Description
User facility returned the device to rwmic on march 18, 2019, and the evaluation was completed by the manufacturer on april 24, 2019.Due to the natural wear within the last 18 years the strands within cable sheath are broken.The further energy supply inevitably led to the formation of an arc and thus the complete destruction of the cable.There are no manufacturing or material defects.
