Post Market Clinical Follow up Study aimed to collect clinical data on safety and efficacy of Robotically Assisted System called Symani to perform microsurgery techniques such as anastomosis, suturing and ligation for open surgery procedures on small anatomical structures such as blood vessels, lymphatic ducts and nerves.
PMCF study aimed to monitor the safety, usability, performance and long-term efficacy of Symani. Furthermore, it will permit to detect potential emerging risks related to safety on the basis of clinical evidence through the observation of patients who have undergone microsurgical reconstructions using the Symani Surgical System in the usual setting of standard surgical practice.

| Surgeon Assessment of Robotic Usability | Surgeons were asked to complete a questionnaire for each patient operated on using the study device. Success was defined as a response of complete or partial procedure success. | 30 days |
| Free Flap Survival at Discharge | This effectiveness endpoint is assessed only for free flap procedures undertaken in the FAS. Subjects were assessed at the time of discharge for free flap survival status.For patients with free flap procedures, the average hospital stay was 11.9 days. | discharge |
