Medical Microinstruments, a robotics company specialising in microsurgery, says its Symani Surgical System was successfully used at Careggi University Hospital Florence by Professor Marco Innocenti, MD, and his team in a complex, post-traumatic limb reconstruction that saved a patient’s arm from amputation. The case is the first enrolled patient in MMI’s post-market study. Prof Innocenti, the head of reconstructive surgery and microsurgery at Careggi University Hospital, performed the procedure which involved a young adult who suffered a motorcycle accident. After eight months of unsuccessful surgeries and bone fixation attempts, the patient received a recommendation for amputation. Prof Innocenti was made aware of the case and determined the patient was a candidate for a free-flap reconstruction, which involved transferring a piece of bone and its vessels from the lower leg to the patient’s forearm. The robotic-assisted procedure successfully restored blood flow to the area despite severe damage and extensive scar tissue inside the arm. Prof Innocenti says: “Robotic-assisted technology is a revolutionary tool for microsurgery, because it allows physicians to complete procedures that are difficult or impossible with the human hand. “By increasing our precision, we can reconnect submillimeter vessels and nerves that enable reconstruction even after severe trauma. I am confident our post-market study will show significant advantages to improving patient outcomes, as the patient in the motorcycle accident would have lost her arm without robotic-assisted microsurgery.” The patient marked the first enrolled in the post-market study. It was also the first time Prof. Innocenti performed a free-flap reconstruction with the fibula bone using the Symani Surgical System. Mark Toland, CEO of MMI, says: “By evolving surgical intervention from a manual process to one that leverages robotic technology, we can open the door to procedures that have never been done before. “Prof Innocenti’s accomplishment in this case is an extremely exciting piece of validation for our technology that will contribute to our data collection for our growing global regulatory strategy.” The Symani Surgical System received CE Mark – indicating European approval – in 2019 and can enhance free-flap reconstructions, replantations, congenital malformations, peripheral nerve repairs and lymphatic surgeries. The platform minimizes hand tremor and scales physician movements (7-20x), reducing the occurrence of thrombosis by 50 percent in preclinical studies. Its NanoWrist instruments are the world’s smallest wristed surgical instrumentation and create seven degrees of freedom for optimal dexterity inside of minimally invasive incisions.
专门从事显微外科手术的机器人公司Medical Microinstruments表示,其Symani外科系统在佛罗伦萨Careggi大学医院被医学博士Marco Innocenti教授和他的团队成功地用于复杂的创伤后肢体重建,使患者的手臂免于截肢。 该病例是MMI上市后研究中的第一例登记患者。 Careggi大学医院重建外科和显微外科的负责人Innocenti教授实施了这项手术,涉及一名遭受摩托车事故的年轻人。 在八个月的手术和骨固定尝试不成功后,病人收到了截肢的建议。 Innocenti教授意识到了这个病例,并确定患者是游离皮瓣重建的候选人,该重建包括将一块骨头及其血管从小腿转移到患者的前臂。 机器人辅助的手术成功地恢复了该区域的血流,尽管手臂内部有严重的损伤和广泛的疤痕组织。 因诺琴蒂教授说:“机器人辅助技术是显微外科手术的革命性工具,因为它允许医生完成用人手难以或不可能完成的手术。 “通过提高精度,我们可以重新连接亚毫米血管和神经,即使在严重创伤后也能重建。我相信我们的上市后研究将显示出改善患者结局的显著优势,因为如果没有机器人辅助的显微手术,摩托车事故中的患者将失去她的手臂。“ 该患者是第一个进入上市后研究的患者。这也是Innocenti教授首次使用Symani手术系统进行腓骨游离皮瓣重建。 MMI首席执行官马克·托兰(Mark Toland)表示:“通过将手术干预从人工过程演变为利用机器人技术的过程,我们可以为以前从未做过的手术打开大门。 “因诺琴蒂教授在此案中的成就是对我们技术的一次极其令人兴奋的验证,这将有助于我们为不断增长的全球监管战略收集数据。” 赛马尼外科系统在2019年获得了CE标志--表明欧洲批准--并可以加强游离皮瓣重建、再植、先天性畸形、周围神经修复和淋巴手术。 该平台最大限度地减少了手震颤和医生运动(7-20x),在临床前研究中,血栓形成的发生率降低了50%。它的纳米仪器是世界上最小的扭力外科仪器,并为微创切口内的最佳灵巧度创造了七个自由度。
