Of the many factors that affect the clinical outcomes of orthopedic surgery, the surgical procedure is the most important. Robotics have been developed to perform the surgical procedures more accurately and consistently. Robotic surgical procedures in the orthopedic field were developed 20 years ago. Some designs of surgical robots have disappeared due to practical problems and complications, and an another design of surgical robots is emerging. To date, the use of robot surgery in arthroplasty is still controversial in terms of the clinical outcomes, practicality, and cost-effectiveness, even though it has been reported to be effective in the alignment and positioning of components in the field of artificial joints. Early robotic surgery was based mainly on active robot surgery according to the scheduled operation without the intervention of the operator. Recently the semi-active system of robotic surgery has been introduced. In a semi-active system, the robot constrains the surgeon to a haptic boundary defined by the computer based on the 3-dimensional imaging preoperative plan, and the operator can change the preoperative plan through real-time feedback during operation.

로봇기술의 발달로 인하여 로봇의 활용 분야는 점차 확대되고 있으며 의료 및 재활분야에도 이용되는 추세이다. 의료분야에 이용되는 메디칼 로봇은 최소 절개 수술에 적용하는 경우 많은 이점을 얻을 수 있다는 점과 전문의사가 현장에 있기 힘든 오지나 낙도 또는 전쟁터 같은 곳에서도 원격 수술이 가능하다는 장점으로 많은 관심을 받고 있다. 원격 수술은 수술 계획, 로봇에게 환자 등록, 원격 수술 시행의 세가지 과정을 거치게 된다. 본 논문에서는 원격 수술을 위한 위 과정의 연구 동향을 기술하고 현재 본 실험실에서 수행하고 있는 연구 내용을 다룬다. 원격 수술을 위한 의료시스템을 구축하기 위해 팬-틸터 구동부를 가지 스테레어 시각 시스템을 제작하고 여기서 얻어지는 정보를 HMD에 투시하여 현장감을 느끼게 만드는 것과 수술대에서 환자를 수술하는 듯한 느낌을 제공할 수 있는 기술인 매스터 조작기와 슬레이브 조작기 사이의 힘 피드백 구현에 대해 다룬다.

This study is a review study attempted to analyze the current situation of surgical robots based on previous research on surgical robots in the era of the 4th revolution, and to forecast the future direction of surgical robots. Surgical robots have made full progress since the launch of the da Vinci and the surgical robot is playing a role of supporting the surgeries of the surgeons or the master-slave method reflecting the intention of the surgeons. Recently, technologies are being developed to combine artificial intelligence and big data with surgical robots, and to commercialize a universal platform rather than a platform dedicated to surgery. Moreover, technologies for automating surgical robots are being developed by generating 3D image data based on diagnostic image data, providing real-time images, and integrating image data into one system. For the development of surgical robots, cooperation with clinicians and engineers, safety management of surgical robot, and institutional support for the use of surgical robots will be required.

A microsurgery telerobotic system has been developed to aid surgeons from physiological tremor, eye stram, hand tremor, contagious and radioactive hazard. This paper identifies four general areas of advanced microsurgery and analyzes the motion, tools, accuracy and applying forces with respect to microsurgery tasks, and proposes the criteria to design the microsurgical robot. The analysis of microsurgery can be helpful to clarify some basic concept and design of surgical robots. Based on this analysis results, we propose an efficient in-parallel-platform manipulator having a special kinematic structure suitable for microsurgery.

환자의 환부를 최소한으로 절개하여 시술하는 최소 침습 수술 수술은 많은 장점을 가지고 있어 그 활용도가 점차 확대되고 있다. 하지만 조작하는 조직으로부터 눈과 손이 분리되어 있기 때문에 많은 문제점들이 발생한다. 그 중 하나는 수술 영역과 시각 영역이 분리되어 발생하는데, 최적의 위치조정을 위한 자동 복강경 수술 로봇 팔 시스템 도입으로 이러한 문제를 해결하고 있다. 본 연구에서는 복강경 수술 로봇 팔을 설계하는데 있어 동작 범위를 빠르게 시각화하여 설계 단계에서 다양한 파리미터를 적용하여 보다 효율적인 복강경 수술 로봇 팔의 설계 방법을 제시한다. 제안된 물리 엔진을 이용한 동작 범위 분석 방법은 역기구학을 계산할 필요가 없으며, 설계가 바뀌어도 추가로 산출해야 하는 수식 없이 바로 수정된 기구학만으로 동작 범위 분석이 가능하다.

This study is about development of technology system for MIS(Minimally Invasive Surgery) robot of S. Korea analysed by the application of scenario planning. MIS robot industry receive attention as a new growth industry for national and international and is noticeable for the leading industry of future era in Korea. In this paper was examined the characteristics of an MIS robot technology and its components. It was investigated about the technology of an overseas MIS robot(especially U.S.A) and Korean domestic MIS robot and understood such as the country's policy propulsion issues then, was searched about development direction of the future. As a result, the future policy for MIS robot of S. Korea is to further spur the development of new MIS robot technology and more improvement of the technology level of MIS robot with AR(Augmented Reality) display.

Medical robot has four fields. Surgery assistant robot, robotic surgery, Surgery Simulator, rehabilitation robot. Thus, medical robots is often high precision and reliability requirements for operations are being developed. Medical service robot's another sector is care for service robots. Care services robot is the hospital's reception work and biometric data acquisition of patients, the hospital in location and content information provide to patients. But now medical service robot practical acceptance process failed to progress. In this paper were the medical service robot systems design and implementation. Implemented the robot system is using the standard protocols for the exchange of medical information and can be linked with hospital information system. The hospital's patient reception and processing, to provide care waiting number information.

Background: In general, cardiac surgery has been performed via median sternotomy. During the past decade, improvements in endoscopic equipment and operative techniques have resulted in development of minimally invasive cardiac operation using small incisions. With the advent of a voice controlled camera-holding robotic arm (AESOP 3000, Automated Endoscope System for Optimal Positioning), cardiac surgery entered the robotic age. Material and Method: Between April 2004 and December 2004, a total of seventy eight patients underwent robotic cardiac surgery, of whom sixty four patients underwent robot-assisted minimally invasive cardiac surgery via 5cm right lateral minithoracotomy using voice controlled robotic arm, femoral vessels cannulation, percutaneous internal jugular cannulation, transthoracic aortic cross clamp. Other fourteen patients underwent MIDCAB via internal mammary artery harvesting using AESOP. Result: Robotic cardiac surgery were mitral valve repair in 37 cases, mitral valve replacement in 10 cases, aortic valve replacement in 1 case, MIDCAB in 14 cases, ASD operation in 9 cases, and isolated Maze procedure in 1 case. In mitral operation, mean CPB time was $165.3\pm43.1$ minutes and mean ACC time was $110.4\pm48.2$ minutes. Median length of hospital stay was 6 days (range 3 to 30) in mitral operation, 4 days (range 2 to 7) in MIDCAB, and 4 days (range 2 to 6) in ASD operation. For complications, 3 patients were required by reoperation for bleeding. There was no hospital mortality. Conclusion: Our experience of robot cardiac surgery suggests that many cardiovascular surgeons will be able to perform minimally invasive cardiac operations through small incisions with robot-assisted video-direction. Well-designed studies and close long-term follow-up will be required to analyze the benefits of robot-assisted operation.

본 논문은 자유 시점조절과 깊이감 조절이 가능한 단일렌즈 양안시 3D 내시경과 Head-mounted display 를 사용한 새로운 로봇수술 시스템을 제안한다. 최근 들어서 여러 양안식 입체영상장치가 의료 영역에 적용되고 있다. 그러나 3D 의료 장비들은 zooming 과 자유로운 시점조절, 그리고 접사를 하는 데에 한계가 존재한다. 입체영상 장비에서 필연적으로 발생하는 이러한 문제점들은 3D 영화를 찍기 위해서 사용되는 것과 같은 2 대의 카메라와 2 개의 렌즈를 사용하는 데에서 원인을 찾을 수 있다. 이러한 문제점들은 Da Vinci 로봇 수술 시스템과 같은 가장 최신의 시스템에서도 해결되지 못하였다. 본 논문에서 제안하는 새로운 시스템은 지금까지 제시된 문제점들을 해결하고, 현재 존재하는 로봇 수술 시스템에 몰입 입체영상 수술이나 증강 현실 수술을 가능하게 하기 위한 목적으로 제안되었다.
