An Observer-based Force Reflection Robust Control for Dual User Haptic Surgical Training System

✓ Walter Edward Dandy (1886–1946) began his surgical training at the Johns Hopkins Hospital in 1910 and joined the faculty in 1918. During the next 28 years at Johns Hopkins, Dandy established a neurosurgery residency training program that was initially part of the revolutionary surgical training system established by William S. Halsted but eventually became a separate entity. Dandy’s residents were part of his “Brain Team,” a highly efficient organization that allowed Dandy to perform over 1000 operations per year, not counting ventriculograms. This team also provided rigorous training in the Halsted mold for the neurosurgical residents. Although exacting and demanding, Dandy was universally admired by his residents and staff. This article describes Dandy’s neurosurgical residency program at Johns Hopkins, and provides personal recollections of training under Walter Dandy.

Abstract Background VR surgery training becomes a trend in clinical education. Many research papers validate the effectiveness of VR based surgical simulators in training surgeons. However, most existing papers employ subjective methods to study the residents’ surgical skills improvement. Few of them investigates how to substantially improve the surgery skills on speciﬁc dimensions.Methods In this paper, we resort to physiological approaches to objectively research quantitative inﬂuence and performance analysis of VR laparoscopic surgical training system for medical students. 41 participants were recruited from a pool of medical students. They conducted four pre and post experiments in the training box. In the middle of pre and post experiments, they were trained on VR laparoscopic surgery simulators (VRLS). When conducting pre and post experiments, their operation process and physiological data (heart rate and electroencephalogram) are recorded. Their performance is graded by senior surgeons using newly designed hybrid standards for fundamental tasks and GOALS standards for colon resection tasks. Finally, the participants were required to ﬁll the questionnaires about their cognitive load and ﬂow experience.Results The results show that the VRLS could highly improve medical students' performance (p < 0.01) especially in depth perception and enable the participants to obtain flow experience with a lower cognitive load.Conclusion The performance of participants is negatively correlated with cognitive load through quantitatively physiological analysis. This might provide a new way of assessing skill acquirement.

SUMMARYThis paper introduces a dual-user training system whose design is based on an energetic approach. This kind of system is useful for supervised hands-on training where a trainer interacts with a trainee through two haptic devices, in order to practice on a manual task performed on a virtual or teleoperated robot (e.g., for an Minimally Invasive Surgery (MIS) task in a surgical context). This paper details the proof of stability of an Energy Shared Control (ESC) architecture we previously introduced for one degree of freedom (d.o.f.) devices. An extension to multiple degrees of freedom is proposed, along with an enhanced version of the Adaptive Authority Adjustment function. Experiments are carried out with 3 d.o.f. haptic devices in free motion as well as in contact contexts in order to show the relevance of this architecture.

The surgical training system in the UK has long been considered to be of a very high standard. However, it is currently under threat from many changes. To assure the quality of the future surgical consultant workforce we have moved away from apprentice-type training towards more ordered education. Although the reduction in hours and years will mean less overall experience there is a genuine belief that improved education and assessment can compensate. It says much for our island mentality that although we belong to the EU we consider European surgical training to be distinct from our own.
