OBJECTIVE: To evaluate practice change after initiation of a robotic surgery program using a clinical algorithm to determine the optimal surgical approach to benign hysterectomy. METHODS: A retrospective postrobot cohort of benign hysterectomies (2009-2013) was identified and the expected surgical route was determined from an algorithm using vaginal access and uterine size as decision tree branches. We excluded the laparoscopic hysterectomy route. A prerobot cohort (2004-2005) was used to evaluate a practice change after the addition of robotic technology (2007)...

This systematic review with a meta-analysis of studies was carried out to evaluate the effectiveness of robotic training (RT) and conventional training (CT) in improving the motor recovery of paretic upper limbs in stroke patients. Numerous electronic databases were searched from January 2000 to May 2016. Finally, 13 randomized-controlled trials fulfilled the inclusion criteria and were included in the three meta-analyses. The first meta-analysis carried out for those studies using RT for stroke patients indicated a significant improvement in the RT groups...

This chapter studies the bidirectional causal interactions between curiosity and learning and discusses how understanding these interactions can be leveraged in educational technology applications. First, we review recent results showing how state curiosity, and more generally the experience of novelty and surprise, can enhance learning and memory retention. Then, we discuss how psychology and neuroscience have conceptualized curiosity and intrinsic motivation, studying how the brain can be intrinsically rewarded by novelty, complexity, or other measures of information...

The deployment of multiple robots for achieving a common goal helps to improve the performance, efficiency, and/or robustness in a variety of tasks. In particular, the observation of moving targets is an important multirobot application that still exhibits numerous open challenges, including the effective coordination of the robots. This paper reviews control techniques for cooperative mobile robots monitoring multiple targets. The simultaneous movement of robots and targets makes this problem particularly interesting, and our review systematically addresses this cooperative multirobot problem for the first time...

We demonstrate the interaction control capabilities of the MR-SoftWrist, a novel MR-compatible robot capable of applying accurate kinesthetic feedback to wrist pointing movements executed during fMRI. The MR-SoftWrist, based on a novel design that combines parallel piezoelectric actuation with compliant force feedback, is capable of delivering 1.5 N·m of torque to the wrist of an interacting subject about the flexion/extension and radial/ulnar axes. The robot workspace, defined by admissible wrist rotation angles, fully includes a circle with a 20 deg radius...

OBJECTIVE: Most trainees begin learning robotic minimally invasive surgery by performing inanimate practice tasks with clinical robots such as the Intuitive Surgical da Vinci. Expert surgeons are commonly asked to evaluate these performances using standardized five-point rating scales, but doing such ratings is time consuming, tedious, and somewhat subjective. This article presents an automatic skill evaluation system that analyzes only the contact force with the task materials, the broad-bandwidth accelerations of the robotic instruments and camera, and the task completion time...

An engineer who becomes an educator in a school of software engineering has the mission to teach how to design and construct software systems, therein applying his or her knowledge and expertise. However, due to their engineering background, engineers may forget that educating a person is not the same as designing a machine, since a machine has a well-defined goal, whilst a person is capable to self-propose his or her own objectives. The ethical implications are clear: educating a free person must leave space for creativity and self-determination in his or her own discovery of the way towards personal and professional fulfillment, which cannot consist only in achieving goals selected by others...

BACKGROUND: The principal objective of the experiment was to analyze the effects of the clutch operation of robotic surgical systems on the performance of the operator. The relative coordinate system introduced by the clutch operation can introduce a visual-perceptual mismatch which can potentially have negative impact on a surgeon's performance. We also assess the impact of the introduction of additional tactile sensory information on reducing the impact of visual-perceptual mismatch on the performance of the operator...

Kara L Watts, Richard Ho, Reza Ghavamian, Nitya Abraham
INTRODUCTION AND HYPOTHESIS: High vesicovaginal fistulas (VVF) in the setting of good apical support are best repaired via a transabdominal approach. Laparoscopic VVF repair was first reported in 1998. Several series of robot-assisted VVF repairs have since been published. The robot-assisted approach allows repair of high apical vaginal fistulas while avoiding the morbidity of laparotomy, shortening convalescence, and facilitating the use of omental interposition flaps. This video presents the technique for robot-assisted extravesical VVF repair utilizing a laparoscopically mobilized omental flap...

BACKGROUND: This randomized, controlled study was designed to compare the effects of recruitment maneuvers (RMs) with a 15 cmH2O positive end-expiratory pressure (PEEP) on the systemic oxygenation and lung compliance of patients with healthy lungs following robot-assisted laparoscopic prostatectomy (RALP). METHODS: Sixty patients undergoing a RALP with an intraoperative 15 cmH2O PEEP were randomly allocated to an RM or a Control group. The patients in the RM group received a single RM through the application of a continuous positive airway pressure of 40 cmH2O for 40 s 15 min after being placed in the Trendelenburg position...

OBJECTIVE: Increased use of robotically assisted thoracic surgery (RATS) necessitates effective credentialing guidelines to ensure safe outcomes. We provide a stepwise algorithm for granting privileges and credentials in RATS. This algorithm reflects graduated responsibility and complexity of the surgical procedures performed. Furthermore, it takes into account volume, outcomes, surgeon's competency, and appropriateness of robot usage. METHODS: We performed a literature review for available strategies to grant privileges and credentials for implementing robotic surgery...

Cor triatriatum sinister (CTS) is a rare congenital cardiac anomaly and is mainly corrected through conventional surgery through sternotomy. We described our successful novel surgical technique of totally robotic correction of CTS in one case of CTS with concomitant repair of atrial septal defect using da Vinci SI Surgical System (Intuitive Surgical, Inc, Sunnyvale, CA USA) with excellent surgical outcome. We conclude that robotic correction of CTS is a feasible and safe alternative to conventional surgical technique...

In this study, we developed a novel unfixed-type experimental system that we call a '3-DOF servosphere.' This system comprises one sphere and three omniwheels that support the sphere. The measurement method is very simple. An experimental animal is placed on top of the sphere. The position and heading angle of the animal are observed by using a high-speed camera installed above the sphere. Because the system can rotate the sphere with three degrees of freedom (DOFs) independently, the position and heading angle at the origin can be maintained without fixing the body...

Robot-assisted surgery on a broad front - without evidence for being cost-effective Robot-assisted surgery is currently heavily marketed. The HTA centre in Region Västra Götaland has produced five HTA reports regarding use of robot-assisted surgery in different clinical situations (prostatic cancer, benign gynaecological surgery, pediatric pyeloplasty and fundoplication, and rectal cancer), finding weak evidence for a patient value. The current report by Per Carlsson et al confirms that robot-assisted surgery indeed leads to increased costs that are not balanced by augmented patient value, i...

There are three common methods for calculating the lift generated by a flying animal based on the measured airflow in the wake. However, these methods might not be accurate according to computational and robot-based studies of flapping wings. Here we test this hypothesis for the first time for a slowly flying Pacific parrotlet in still air using stereo particle image velocimetry recorded at 1000 Hz. The bird was trained to fly between two perches through a laser sheet wearing laser safety goggles. We found that the wingtip vortices generated during mid-downstroke advected down and broke up quickly, contradicting the frozen turbulence hypothesis typically assumed in animal flight experiments...
