Event or Problem Description
According to the reporter, during a laparoscopic thoracoscopic lobectomy procedure, while resectioning the pulmonary parenchyma by right upper lobectomy, a cracking sound was heard when the firing advanced about 2cm.The firing was able to be completed, but the jaws did not open when the surgeon attempted releasing the device by pulling the black return knob.It was noted that the internal gear and the black return knob were damaged.An additional resection was performed using another reload and handle.This led to tissue damage and 30 minutes or more extended surgical time.
Additional Manufacturer Narrative
Additional information: g3, h3, h6 h3 evaluation summary: medtronic conducted an investigation based upon all information received.The device was available for evaluation.Visual inspection noted the device was applied past protruding staples, engaged in interlock, the jaws were clamped, and the knife bar assembly was a dvanced and the device had damaged laminates.Functionally, the i-beam could not be fully retracted.The returned reload could not be unloaded from the returned handle.The jaws were not fully closed and the anvil was found to be deformed.It was reported that the jaws of the device remain closed on tissue.The reported issue was confirmed.The most likely cause was determined to be manufacturing related.The most likely cause was determined to be manufacturing related.Bent knife laminates can occur from improper component orientation.The bent knife laminates push the interlock legs down causing the interlock to fail.This issue can also occur when the device is applied on over-indicated tissue.Internal process improvements have been initiated to mitigate this issue.The instructions included with this device provide the following guidance: failure to completely fire the reload will result in an incomplete cut and/or incomplete staple formation, which may result in poor hemostasis and/or leakage.Always inspect the tissue thickness and select an appropriate staple size prior to application of the stapler.Overly thick or thin tissue may result in unacceptable staple formation.When positioning the stapler on the application site, ensure that no obstructions, such as clips, are incorporated into the instrument jaws.Firing over an obstruction may result in incomplete cutting action and/or improperly formed staples.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
