HKUMed was the first in Hong Kong to utilise robotic arm technology for joint replacement surgery in public hospitals. This technology can be applied during surgical planning, bone removal, and implant placement. Compared with conventional joint replacement, robotic arm-assisted surgery has been proved in international studies to have higher accuracy and consistency in implant positioning, and to be safer with less soft tissue trauma, less postoperative pain, earlier functional recovery, lower revision rates, and fewer complications. 學院開啟了本港公立醫院運用機械臂技術進行關節置換 手術的先河。此技術可應用於術前計劃、磨骨及假體植入。 與傳統關節置換手術相比,國際研究證明機械臂輔助手術更 精確、更安全,減少軟組織創傷與術後疼痛,加快病人康復, 並降低翻修率與併發症風險。 At HKUMed, the clinical application of 3D printing has improved the efficiency of orthopaedic surgery in multiple ways. Prior to surgery, patient-specific anatomic models can be produced to help surgeons plan surgical procedures, 3D-printed fixators and splints to help enhance accuracy, thereby expediting recovery and rehabilitation. Customised implants can also be made locally, saving time and cost. With a generous donation from the Tam Shiu Charitable Trust, the Tam Shiu Anatomical Modelling Laboratory was established in 2018. Since then, it has collaborated with Queen Mary Hospital to design and produce the 3D-printed fixators, sprints and implants for clinical use in all local hospitals as well as some overseas hospitals, and the number of patient cases served is on the rise. 學院近年將3D打印應用於臨床服務,全面提升骨科手 術的效率,包括術前為病人度身訂製解剖模型,協助外科 醫生進行術前評估和計劃;3D打印的手術工具和組件讓手 術更精確,有助加快病人康復;而在本港製作植入物,可 節省時間和成本。承蒙譚兆慈善基金慷慨捐貲,港大譚兆 基金3D人體模型實驗室於2018年成立,自此與瑪麗醫院 合作,為全港醫院及部分海外醫院設計及生產上述3D打印 物品供臨床使用,所處理的病例數目亦見增長。 Robotic Arm-assisted Joint Replacement Surgery 機械臂輔助關節置換手術 3D Printing in Surgery 3D打印技術創新手術治療 41 HKUMed News Winter 2023
