Article Abstract
This study introduces an innovative master-slave cardiac ablation catheter robot system that employs magnetorheological fluids. The system incorporates magnetorheological fluid to enable collision detection through haptic feedback, thereby enhancing the operator's situational awareness. A modular clamping and propulsion mechanism has been engineered for the ablation catheter, facilitating omnidirectional operation and force feedback within the cardiac cavity. To evaluate the proposed system, an in vitro experiment was performed. Results from the experiment indicate that the system demonstrates high motion transmission accuracy. Furthermore, the system effectively alerts operators to potential collisions, enabling swift catheter position adjustments, minimizing the risk of vascular perforation, and ultimately enhancing the overall safety and efficiency of the procedure.

Telerobotic surgery has undergone remarkable advances over the past two decades, driven by the integration of sophisticated robotic platforms and modern communication technologies, thereby alleviating many constraints of conventional surgical procedures. Building upon previous studies that focused on individual specialties or specific innovations, this review provides a comprehensive and integrated perspective by tracing the evolution of the field and highlighting applications in gastroenterology, urology, neurology, and cardiology. Landmark achievements include the 2001 transatlantic remote cholecystectomy and the introduction of next-generation platforms such as the Hinotori surgical robot, enabling low-latency remote interventions.

Objectives: Teaching dental anesthesia techniques poses a considerable challenge, primarily due to the limited availability of tools that effectively replicate clinical procedures in preclinical settings. Over the past decade, haptic dental simulators have emerged as promising training aids for various dental procedures, including local anesthesia. This study aimed to evaluate the educational value of a haptic dental simulator in teaching the inferior alveolar nerve block (IANB) technique by assessing the experiences and perceptions of dental students with varying levels of clinical exposure.

Introduction/background: Virtual dental simulators with a haptics component have been used with great success in dental education for over a decade and is becoming an integral part of dental curricula. A large number of studies have been published about the users' perception, acceptance and attitude towards virtual dental simulators. However, no longitudinal or long-term studies to our knowledge have been conducted to evaluate the users' acceptance over time.

As the metaverse blurs the lines between physical and virtual realms, enhanced by haptic devices providing sensory feedback, it is poised to become integral to daily life. However, this new digital frontier is also a site for sexual violence. Women users increasingly report non-consensual touching, image-based sexual abuses and novel forms of gendered harm, often trivialised and inadequately addressed by current laws.

While both techniques have demonstrated success in evoking meaningful sensations in the upper limb, they have only been investigated in separate studies with different patient populations, and thus their perceptual characteristics have never been systematically compared to determine the relative advantages and limitations of each approach. In this study, we directly compared the perceived sensations evoked by ICMS and PNS to those evoked by mechanical touch in a participant with sensory incomplete spinal cord injury.
