Virtual reality simulators: Current status in acquisition and assessment of surgical skills

ANZ JOURNAL OF SURGERY, Issue 1 2002
Peter H. Cosman
Medical technology is currently evolving so rapidly that its impact cannot be analysed. Robotics and telesurgery loom on the horizon, and the technology used to drive these advances has serendipitous side-effects for the education and training arena. The graphical and haptic interfaces used to provide remote feedback to the operator , by passing control to a computer , may be used to generate simulations of the operative environment that are useful for training candidates in surgical procedures. One additional advantage is that the metrics calculated inherently in the controlling software in order to run the simulation may be used to provide performance feedback to individual trainees and mentors. New interfaces will be required to undergo evaluation of the simulation fidelity before being deemed acceptable. The potential benefits fall into one of two general categories: those benefits related to skill acquisition, and those related to skill assessment. The educational value of the simulation will require assessment, and comparison to currently available methods of training in any given procedure. It is also necessary to determine , by repeated trials , whether a given simulation actually measures the performance parameters it purports to measure. This trains the spotlight on what constitutes good surgical skill, and how it is to be objectively measured. Early results suggest that virtual reality simulators have an important role to play in this aspect of surgical training. [source]

Advanced da Vinci surgical system simulator for surgeon training and operation planning

THE INTERNATIONAL JOURNAL OF MEDICAL ROBOTICS AND COMPUTER ASSISTED SURGERY, Issue 3 2007
L. W. Sun
Abstract Background Although patients benefit considerably from minimally invasive surgery, the use of new instruments such as robotic systems is challenging for surgeons, and extensive training is required. Method We developed a computer-based simulator of the da Vinci Surgical System, modelling the robot and designing a new interface. Results The simulator offers users a two-handed interface to control a realistic model of the da Vinci robot. The simulator can be applied (i) to provide an environment in which to practice simple surgical skills and (ii) to serve as a visualization platform on which to validate port placement and robot pose for operation planning. Conclusions Virtual reality is a useful technique for medical training. The simulator is currently in its early stages, but this preliminary work is promising.

Commercializing new technologies: consumers' response to a new interface

THE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 5 2002
Paschalina (Lilia) Ziamou
Successful commercialization of new technologies is the riskiest and most rewarding form of new product development activity. New technologies are often commercialized using innovative interfaces that determine how consumers interact with a new product to obtain its functionality. Consumers' perception of uncertainty about the performance of a novel interface is a key issue in the acceptance of new products involving new interfaces. Specifically, when firms commercialize a new interface, they face two major challenges: First to identify the optimal functionality for the new interface, and second, to effectively communicate with consumers in order to reduce uncertainty about the performance of the new interface and increase adoption intentions. Despite the theoretical and managerial importance of research on consumers' response to a novel interface, very little empirical research has been conducted in this area. Building on prior research on new product development, human-computer interaction, and consumer decision-making, this article examines the factors that influence consumers' judgments of uncertainty about the performance of a new interface and consumers' adoption intentions. Specifically, we conducted an experiment to investigate the effect of the newness of the functionality of a new product and the effect of imagery on consumers' uncertainty about the performance of a novel interface and consumers' adoption intentions. Our results show that consumers perceive lower uncertainty about the performance of a new interface and higher intentions to adopt a new product when the new interface is introduced with a new (vs. pre-existing) functionality. Furthermore, our results suggest that when a new interface is introduced with a new functionality, imagining the product in use increases consumers' uncertainty about the performance of the new interface and decreases their intention to adopt the new product. In contrast, when a new interface is introduced with a pre-existing functionality, imagining the product in use decreases consumers' uncertainty about the performance of the new interface and increases their intention to adopt the new product. Our findings provide valuable guidelines for marketers in formulating new product development and communication strategies for new products involving a new interface. © 2002 Elsevier Science Inc.

Interactive functional poly(vinylidene fluoride) membranes with modulated lysozyme affinity: a promising class of new interfaces for contactor crystallizers

POLYMER INTERNATIONAL, Issue 12 2009
Annarosa Gugliuzza
Abstract BACKGROUND: One of the challenges of current researches in biotechnological fields is the achievement of regular and increasingly smaller protein crystals for genomics and biocatalyst applications. The membrane contactor-based methodology appears to be a time-effective and economically competitive technology for accomplishing this target. RESULTS: A new class of interactive polymeric interfaces enabling the nucleation of very small protein crystals in a short time through controlling attractive interactions is discussed. Specifically, the role of attractive interfacial forces between a model lysozyme solution and modified poly(vinylidene fluoride) membranes is examined. The insertion of amphiphilic motifs in the fluorinated membranes allows quicker agglomeration of protein crystals at the membrane surface reducing significantly the induction time for protein nucleation. The chemical nature of the modifier permits the modulation of the membrane affinity to the lysozyme, involving polar and non-polar attractive interactions and preserving intrinsic structural features, transport properties and the hydrophobic character of the interfaces, according to the basics of membrane crystallization technology. The formation of critical nuclei is observed after 3 h and micro-sized crystals are formed in less than 24 h. CONCLUSION: The experimental evidence suggests these membranes as a promising class of interactive interfaces that may rapidly bring advances in genomics research.
