The subject device was returned to service center for an evaluation.A visual inspection was performed on the returned device and found the ceramic insulation at the distal end of the resection sheath broken off into multiple pieces.An attempted to reconstruct the ceramic tip by using adhesive to temporarily bond the broken piece(s) of the ceramic tip to the distal end of the resection sheath was performed.Approximately 20 percent of the insulation tip was still missing from the device and not returned for an evaluation.Further findings, include indentations on the sheath, and fading of the olympus logo, lot number and model name.Per the instructions for use: "visually inspect the ceramic insulation at the sheath¿s distal end before each use.Do not use the instrument in case of damage (e.G.Cracks, fractures).Warning risk of injury impact, fall, shock or similar stress can damage the ceramic insulation at the sheath¿s distal end.Damaged instruments can cause injuries to the patient and/or user.Do not use the instrument if damaged." based on the evaluation, the likely cause of the broken ceramic insulation tip is due to mishandling.
