“…Academic research efforts continué exploring the boundaries of the capabilities of VR technologies. As an example, the SINERGIA laparoscopic simulator explored the área of perceptual skills [83,84] . The simulator was conceived as a means for training and assessment of motor skills on the first stages of surgical formation, comprising seven didactic units (Fig.…”

Training and assessment paradigms for laparoscopic surgical skills are evolving from traditional mentortrainee tutorship towards structured, more objective and safer programs. Accreditation of surgeons requires reaching a consensus on metrics and tasks used to assess surgeons' psychomotor skills. Ongoing development of tracking systems and software Solutions has allowed for the expansión of novel training and assessment means in laparoscopy. The current challenge is to adapt and include these systems within training programs, and to exploit their possibilities for evaluation purposes. This paper describes the state of the art in research on measuring and assessing psychomotor laparoscopic skills. It gives an overview on tracking systems as well as on metrics and advanced statistical and machine learning techniques employed for evaluation purposes. The later ones have a potential to be used as an aid in deciding on the surgical competence level, which is an important aspect when accreditation of the surgeons in particular, and patient safety in general, are considered. The prospective of these methods and tools make them complementary means for surgical assessment of motor skills, especially in the early stages of training. Successful examples such as the Fundamentáis of Laparoscopic Surgery should help drive a paradigm change to structured curricula based on objective parameters. These may improve the accreditation of new surgeons, as 1 To whom correspondence and reprint requests should be addressed at Bioengineering and Telemedicine Centre (GBT), ETSI Telecomunicación, Universidad Politécnica de Madrid (UPM).

“…Training in SINERGIA SINERGIA [23] is a VR simulator designed for the learning of basic skills in laparoscopic surgery. Two main contributions arise from this global aim: (1) a specification of didactic exercises that has reverted into the creation of a new training environment; (2) an appropriate use of the simulations technologies that significantly improved the whole simulation.…”

Purpose Surgical simulators are currently essential within any laparoscopic training program because they provide a low-stakes, reproducible and reliable environment to acquire basic skills. The purpose of this study is to determine the training learning curve based on different metrics corresponding to Ave tasks included in SINERGIA laparoscopic virtual reality simulator. Methods Thirty medical students without surgical experience participated in the study. Five tasks of SINERGIA were included: Coordination, Navigation, Navigation and touch, Accurate grasping and Coordinated pulling. Each participant was trained in SINERGIA. This training consisted of eight sessions (R1-R8) of the Ave mentioned tasks and was carried out in two consecutive days with four sessions per day. A statistical analysis was made, and the results of Rl, R4 and R8 were pair-wise compared with Wilcoxon signed-rank test. Significance is considered at P value <0.005. Results In total, 84.38 % of the metrics provided by SINER-GIA and included in this study show significant differences when comparing Rl and R8. Metrics are mostly improved in the Arst session of training (75.00 % when Rl and R4 are compared vs. 37.50 % when R4 and R8 are compared). In tasks Coordination and Navigation and touch, all metrics psychomotor skills are improved. On the other hand, Navigation just improves 60 % of the analyzed metrics. Most learning curves show an improvement with better results in the fulfillment of the different tasks. Conclusions Learning curves of metrics that assess the basic psychomotor laparoscopic skills acquired in SINERGIA virtual reality simulator show a faster learning rate during the Arst part of the training. Nevertheless, eight repetitions of the tasks are not enough to acquire all psychomotor skills that can be trained in SINERGIA. Therefore, and based on these results together with previous works, SINERGIA could be used as training tool with a properly designed training program.

“…Currently, there are many application has been developed to be used as training aid for minimal invasive surgery (MIS) or laparoscopy [12]- [14]. SINERGIA laparoscopic virtual reality simulator is an application that provide exercises for specific skill acquisition -coordination, speedy coordination, navigation, navigation and touch, accurate grasping, grasp and transfer, coordinate pulling, force sensitivity and accurate cutting [12]. The MISTELS system (McGill Inanimate System for Training and Evaluation of Laparoscopic Skills) has been designed to provide a series of tasks that performed under video guidance in a box using standard laparoscopic instruments to objectively assess basic laparoscopic skills [14].Another virtual reality simulator that is computer based developed is MIST-VR (Mentice AB, Gothenburg, Sweden) that includes interfaces with two laparoscopic instruments passed through a frame containing a tracking device [13].…”

Abstract-Minimal invasive surgery or laparoscopy has taken part especially for pediatrics. Traditionally, medical students learn surgical skills through the mentorship model during their residency training. As technology evolves, more and more applications, simulations and system are built as aids to medical students in acquiring surgical skills. This research is conducted to identify how haptics technology can play part in shaping student skills in Surgery Department of HUKM. This paper will discuss the second phase of the research: Design and Development that focus on simulation class structure based on preliminary analysis. Results show that current training approaches have some weaknesses that can be replaced by applying simulations with haptics devices. Proposed structure will be tested in development stage. It is a hope that this research will enrich the literature review for visual informatics area.
