摘要： Miniaturization of surgical robots for insertion inside the peritoneal cavity has become a new trend in Robotic Minimally Invasive Surgery (R-MIS) [1–4]. Robots for laparo-endoscopic single site surgery (LESS) and natural orifice translumenal endoscopic surgery must be fast enough to react to surgeon input, and be capable of providing high levels of force for effective tissue interactions. Size is a key design factor for in vivo robotics. With conventional actuation methods (electric motors), there exists a tradeoff between the scale of the robot and its load capacity and actuation speed. An alternative actuation scheme is to exploit the high power density of fluidic (pneumatic or hydraulic) actuators. However, fabrication of miniature but powerful fluidic linear and rotary actuators with desired sizes has been a challenge due to difficulties in sealing at high pressures, obtaining necessary surface finishes, and associated cost of fabrication.

摘要： Study Objective: To measure the safety culture in the robotics surgery operating room before and after implementation of the Robotic Operating Room Computerized Checklist (RORCC). Design: Prospective study. Subjects: Gynecology surgical staff (n = 32). Setting: An urban community hospital. Interventions: The Safety Attitudes Questionnaire domains examined were teamwork, safety, job satisfaction, stress recognition, perceptions of management, and working conditions. Questions and domains were described using percent agreement and the Cronbach alpha. Paired t-tests were used to describe differences before and after implementation of the checklist. Measurements and Main Results: Mean (SD) staff age was 46.7 (9.5) years, and most were women (78%) and worked full-time (97%). Twenty respondents (83% of nurses, 80% of surgeons, 66% of surgical technicians, and 33% of certified registered nurse anesthetists) completed the Safety Attitudes Questionnaire;6 were excluded because of non-matching identifiers. Before RORCC implementation, the highest quality of communication and collaboration was reported by surgeons and surgical technicians (100%). Certified registered nurse anesthetists reported only adequate levels of communication and collaboration with other positions. Most staff reported positive responses for teamwork (48%;alpha = 0.81), safety (47%;alpha = 0.75), working conditions (37%;alpha = 0.55), stress recognition (26%;alpha = 0.71), and perceptions of management (32%;alpha = 0.52). No differences were observed after RORCC implementation. Conclusion: Quality of communication and collaboration in the gynecology robotics operating room is high between most positions;however, safety attitude responses are low overall. No differences after RORCC implementation and low response rates may highlight lack of staff support. (C) 2014 Published by Elsevier Inc. on behalf of AAGL.

摘要： The article discusses the description of robot-like machines before the utilization of the word robots in a paper title in 1973. Topics include the lecture titled 'Automation and the Good Life,' given by Alfred V. Bodine, the recipient of the 1962 small/medium-sized enterprise (SME) Eli Whitney Productivity Award, the need for the TP58PUB14 automation to meet national growth, and the description of the implementation of a production robotic system in TP85PUB442 active end-effector.

摘要： Simulation is a powerful tool that has a very important role in the different areas of research, development, and education. In particular, simulation tools are widely used in robotics. In this article, we present an active learning experience based on simulation tools in the framework of robotics courses taught at engineering degrees. It is well known that the field of robotics involves many disciplines taught in higher education, such as mechanics, electronics, or computer science. In the context of a robotics course for an Industrial Engineering Masters degree, the different topics addressed can benefit from the use of simulation tools. Additionally, the benefits of active learning activities have been widely acknowledged and discussed. The main contribution of this work is the simulation tools fully integrated in the project-based activity designed. Thus, one of the contributions is the software provided, developed with a clear teaching focus, and the successful teaching experience with a high academic level thanks in part to the simulation tools. Here, we describe the methodology and the new simulation tools, RobotScene and SGRobot, developed for this project-based learning activity. This activity has been carried out successfully for several years;and our experience is that it motivates the students and improves their understanding of the theoretical concepts involved. We also present the academic results that support the benefits of the activity presented. (C) 2011 Wiley Periodicals, Inc.

摘要： Background. Modular lower extremity robotics may offer a valuable avenue for restoring neuromotor control after hemiparetic stroke. Prior studies show that visually guided and visually evoked practice with an ankle robot (anklebot) improves paretic ankle motor control that translates into improved overground walking. Objective. To assess the feasibility and efficacy of daily anklebot training during early subacute hospitalization poststroke. Methods. Thirty-four inpatients from a stroke unit were randomly assigned to anklebot (n = 18) or passive manual stretching (n = 16) treatments. All suffered a first stroke with residual hemiparesis (ankle manual muscle test grade 1/5 to 4/5), and at least trace muscle activation in plantar-or dorsiflexion. Anklebot training employed an "assist-as-needed" approach during >200 volitional targeted paretic ankle movements, with difficulty adjusted to active range of motion and success rate. Stretching included >200 daily mobilizations in these same ranges. All sessions lasted 1 hour and assessments were not blinded. Results. Both groups walked faster at discharge;however, the robot group improved more in percentage change of temporal symmetry (P =.032) and also of step length symmetry (P =.038), with longer nonparetic step lengths in the robot (133%) versus stretching (31%) groups. Paretic ankle control improved in the robot group, with increased peak (P <= .001) and mean (P <= .01) angular speeds, and increased movement smoothness (P <= .01). There were no adverse events. Conclusion. Though limited by small sample size and restricted entry criteria, our findings suggest that modular lower extremity robotics during early subacute hospitalization is well tolerated and improves ankle motor control and gait patterning.

摘要： BackgroundIntra-operative imaging is widely used to provide visual feedback to a clinician when he/she performs a procedure. In visual servoing, surgical instruments and parts of tissue/body are tracked by processing the acquired images. This information is then used within a control loop to manoeuvre a robotic manipulator during a procedure. MethodsA comprehensive search of electronic databases was completed for the period 2000-2013 to provide a survey of the visual servoing applications in medical robotics. The focus is on medical applications where image-based tracking is used for closed-loop control of a robotic system. ResultsDetailed classification and comparative study of various contributions in visual servoing using endoscopic or direct visual images are presented and summarized in tables and diagrams. ConclusionThe main challenges in using visual servoing for medical robotic applications are identified and potential future directions are suggested. 'Supervised automation of medical robotics' is found to be a major trend in this field. Copyright (c) 2013 John Wiley & Sons, Ltd.
