Manufacturer Narrative
The green stapler reload was not returned to isi for failure analysis evaluation; therefore, the root cause of the customer reported failure mode cannot be determined. A follow-up mdr will be submitted if the instrument is returned (post engineering evaluation) or if additional information is received. This complaint is being reported due to the following conclusion: during a da vinci assisted surgical procedure, the surgeon observed malformed staples after firing the stapler 45 instrument with a green stapler reload installed, requiring the surgeon to suture the patient's tissue. It is unknown what caused or contributed to the malformed staples issue.
 
Event Description
It was reported that during a da vinci assisted surgical procedure, during use of the stapler 45 instrument, the surgeon observed that the staples in the patient's bronchus were malformed. The surgeon made the decision to suture the patient's bronchus. On 06-19-2017, additional information regarding the reported event was provided by the intuitive surgical, inc. (isi) specialty sales representative (ssr) who initially reported this complaint. According to the ssr the planned surgical procedure was a da vinci assisted pulmonary lobectomy procedure. After transecting the patient's bronchus tissue using the stapler 45 instrument with a green stapler reload installed, the surgeon observed malformed staples. The ssr indicated that the affected tissue thickness appeared to be normal and the surgeon was able to obtain an adequate clamp. The ssr indicated that it is unknown if the patient had undergone any radiation or chemotherapy treatments. During use of the instrument, there were no issues noted. The surgeon does not know what caused the malformed staples issues. On 06-21-2017 the ssr provided photograph images of the affected green stapler reload and the affected tissue. Review of the photographs found that the photograph of the affected tissue was quite blurry. There was no observation of the photograph that showed anything that would have contributed to the malformed staples issue experienced by the surgeon. Review of the photograph of the affected green stapler reload showed that there were a couple of pushers towards the reload's proximal end that appeared to be lower than the rest of the pushers; however, review of the photograph was unable to confirm if the affected pushers were never fully deployed, or if they properly deployed, and then fell down after completion of the stapler 45 instrument's firing sequence.
