Manufacturer Narrative

Based on the current information provided, the cause of the post-operative cerebral hemorrhage is unknown. Isi has requested for the stapler 45 instrument, a blue stapler 45 reload, and stapler motor pack (smp) for evaluation. However, as of the date of this report, isi has not received the products for failure analysis. A follow-up mdr will be submitted if additional information is obtained. Isi has reviewed the site¿s system logs. The first smp/stapler combo used was smp (serial # (b)(4)) with stapler (part #410298-11; lot #s10170215-823) with a blue stapler 45 reload installed. While this combo was installed, the system logs show multiple error 32070 pointing to communication issues between the smp and icb. In addition, a single low rom homing failure occurred and two error 32030 faults were generated. The system was power cycled two times. There were no clamps or fires attempted with this stapler instrument and smp combo. Later in the procedure, the surgical staff replaced the smp and stapler instrument. The surgical staff used smp (serial # (b)(4)) with stapler 45 instrument (lot #t10180613-728) with blue stapler 45 reloads installed. With this combo installed, the logs show that six blue stapler reloads were fired; however, only five of the firings were completed. A partial fire (error 32075 in system logs) occurred on the fifth firing. The firing failed at 79% completion. There was one incomplete clamp in two clamp attempts on this install. There were no other installs that had incomplete clamps). Around 1. 5 hours after the last stapler firing, smp (serial # (b)(4)) with stapler 45 instrument (lot # s10170215-823) were installed again. During this install, the system logs show more error 32070 faults pointing to a voltage/current error on the smp. There was one homing failure. No clamps or fires were attempted with this stapler instrument and smp combo. Isi has reviewed the site's complaint history. No related complaints have been identified. This complaint is being reported due to the following conclusion: after undergoing a da vinci-assisted gastrectomy procedure, the patient suffered a cerebral hemorrhage. As a result, the patient underwent another unspecified surgical procedure. However, the cause of the post-operative complication is unknown. Blank mdr fields: follow-up was attempted, but the patient information was either unknown or unavailable. The expiration date is not applicable. Implant date is blank because the product is not implantable. The sections are not available for the site.

Event Description

It was reported that after undergoing a da-vinci-assisted gastrectomy procedure, the patient suffered a cerebral hemorrhage and required another unspecified operation. The surgeon reportedly commented that ¿it cannot be said that it is a direct cause, but it was a patient with a tendency to bleed from the preoperative stage. ¿ during the da vinci-assisted surgical procedure, the surgical staff encountered an error 32030 issue while using a stapler 45 instrument. An error 32030 is generated when the system cannot communicate with one of the instrument control box (icb) nodes. When the error is generated, stapler instruments may not be supported. At that moment, the surgical staff contacted an intuitive surgical, inc. (isi) technical support engineer (tse) for assistance. After the surgical staff performed a hard power cycle of the vision side cart (vsc) and replaced the stapler 45 instrument, the error 32030 issue was resolved. At that time, there was no report of any patient harm or injury. It was reported that approximately 3 hours later, the surgical staff encountered an error 32075 issue in the middle of stapler fire. An error 32075 is a recoverable fault that is generated when the system detects that the firing operation could not be completed. The surgical staff contacted a tse again for assistance. After recovering from the fault and removing the stapler instrument, the surgical staff installed a new stapler reload on the instrument. The surgical staff then reinstalled the stapler instrument and proceeded with the procedure. The surgeon commented that due to the trouble of the stapler instrument(s), the surgical procedure took an extra hour than the original scheduled operation time. At an unspecified time post-operatively, the patient experienced a cerebral hemorrhage. As a result, the patient underwent another unspecified surgical procedure.
