“…The biomechanical physical behavior of the tissues was implemented using the SOFA simulation toolkit for medical applications, 29 which possess GPU real-time parallel implementations of mass spring, 30 tensor-mass, 31 and finite elements methods (FEMs) 32 . The simulation was implemented as a multimodel representation composed of 4 domains running concurrently: the biomechanical behavior, geometric, visual, and haptic spaces, all synchronized through mapping operations during a simulation loop (Fig.…”

Introduction: Microsurgery clipping is one of the most challenging surgical interventions in neurosurgery. The opportunities to train residents are scarce, but the need for accumulating practice is mandatory. New simulating tools are needed for skill learning. Methods: The design, implementation, and assessment of a new hybrid aneurysm clipping simulator are presented. It consists of an ergonomic workstation with a patient head mannequin and a physics-based virtual reality simulation with bimanual haptic feedback. The simulator recreates scenarios of microsurgery from the patient fixation and the exploration of the brain lobes through Sylvian fissure and vascular structures to the aneurysm clipping. Skill metrics were introduced, including monitoring of gestures movements, exerted forces, tissue displacements, and precision in clipping. Results: Two experimental conditions were tested: (1) simple clipping without brain tissue exploration and (2) clipping the aneurysm with brain Sylvian fissure exploration. Differences in the bimanual gestures were observed between both conditions. The quantitative measurements of tissue displacement of the brain lobes exhibited more tissue retrieval for the surgical gestures of neurosurgeons. Appraisal with questionnaires showed positive scores by neurosurgeons in all items evaluating the usability and realism of the simulator. Conclusions: The simulator was well accepted and feasible for training purposes. The analysis of the interactions with virtual tissues offers information to establish differential and common patterns between tested groups and thus useful metrics for skill evaluation of practitioners. Future work can lead to other tasks during the intervention and the inclusion of more clinical cases.

“…Recent advances in VR based training systems assisted by haptic/tactile-feedback, have been treated as promising ways to acquire dexterous catheter manipulation skills. Research towards the development of immersive VR simulators has inspired studies to formulate physical models of both vessels [20], [21] and catheter [22], [23]. With the consideration of tissue-protection, Wang et al made contributions to avoiding possible collisions between catheter tip and vascular wall by both visual and haptic cues [24].…”

In the clinical vascular interventional surgery, experienced surgeons usually rely on visual feedback to reason tool-tissue interaction, because haptic forces are easily contaminated by frictions between the catheter and the introducer sheath, which brings difficulty in collision force perceptions. Thus, cognitive skills are highly demanded for novice surgeons to thoroughly interpret the relative positions between tool and tissue in images and make appropriate decisions about further catheter motions in case of collisions. In this paper, an operator's cognitive skills training system has been introduced, which exploits the tactile sensation to reinforce the visualized spatial positions between catheter tip and vascular wall in the VR simulator. In cooperation with the collision alert module (CAM) in the VR simulator, the newly developed catheter manipulator can provide tactile sensations for novices when catheter tip is threaded beyond safety boundary, so that the VR exhibited tool-tissue interaction can be deliberately intensified. For demonstrating such tactile sensations adequate to strengthen visions, the system model has been established to facilitate the analysis in the perspective of operator's kinesthetic perception. A series of experiments have been conducted at last and the results reveal that the catheter manipulator can not only realize the accurate catheter motions but also provide the enough tactile sensations for novices. Moreover, statistical data prove that subjects under cognitive trainings have developed the ability to interpret the relative spatial positions between catheter tip and vascular wall. Such findings support that the operator's cognitive skills can be enhanced by the tactile reinforcement of VR visualized tool-tissue interaction.
