Additional Manufacturer Narrative
The sureform 60 stapler instrument and multiple white reload accessories were re-evaluated by the intuitive surgical inc., (isi) quality engineering (qe) team.Following information was obtained : the probable root cause of the reported complaint is attributed to loose staples from firing across staple lines or not having a full bundle of tissue between the jaws during use.Loose staples that do not go into tissue can be dragged into the i-beam slot as the i-beam retracts during unclamping.Increased drive train friction during calibration due to a staple lodged in the path of the i-beam can prevent the instrument from registering the reload color, which then results in an initialization failure.
