Reliable control of surgical robots and stabilization of long short-term memory neural networks
… such as collision avoidance in multi-arm robots, and safe control under time-delays in communication are formulated as a control system design problem and studied under a Lyapunov framework. A study on a widely used recurrent neural network is also presented from a dynamical systems …

Tissue classification from electric impedance spectroscopy for haptic feedback in minimally invasive surgery
Haptic feedback is missing in teleoperated surgical robots creating a sensory disconnect from the surgeon and their patient. This thesis proposes using the electric impedance of tissues, instead of the traditionally used mechanical impedance, to develop haptic feedback for surgical robots. Electric …

Sensors and structured beams in optical coherence tomography
… built as a tactile sensor for implementation in surgical robots. A tactile sensor, often referred to as a force sensor, is a device that is sensitive to applied force or pressure. Since the system has a high sensitivity to pressure and a compact size, the sensor is compatible with the surgical …

The experiences of nurses with communication encounters when assisting in robotic-assisted surgery (RAS)
… role in the success of robotics programmes and surgical outcomes. However, few studies have explored the perspective of registered nurses, and none have focused on their experiences of communication. Aim. This study aimed to explore nurses' experiences with communication and their significance …

Design and development of robotic system for endovascular procedures
… surgery, surgeons have complete control on the surgical tool, but in the case of endovascular procedures, a highly flexible tool, which is operated from distal end provides an indirect control. Moreover, the operating end of these flexible tools inside a patient are controlled from distal end, …

ROBOTIC TELESURGERY: AN INVESTIGATION OF UTILITY, HUMAN ADAPTATION, AND PERFORMANCE
… compared to conventional methods. Although surgical robots have the potential of long distance control, insufficient data is available to determine whether long distance robotic surgery, or telesurgery, is practical. Telesurgery could provide multiple benefits, including dissemination of …

Tethered Magnetic Serial Robots for Minimally Invasive Neurosurgery
… demand for smaller, more manoeuvrable, surgical robot tools to reduce the invasiveness of neurosurgical procedures. A magnetic approach to surgical robots could enable smaller tools, but no viable magnetic robot approach exists. Existing magnetic approaches to surgical tasks involve …

Design and fabrication of a prototype aluminum nitride-based pressure sensor with finite element analysis and validation
… to place a needle during a brain CT biopsy, surgical robots have become ubiquitous in clinical surgeries. Despite its advantages and success in surgeries, the interactions between the robot and the surgeons remain deficient, especially for the pressure sensing which plays an important role. …

HeartLander Surgical Feasibility and Commercialization
… tachycardia ablation via the HeartLander Surgical robot is a commercially feasible method for relieving patients from arrhythmia symptoms. HeartLander’s technology meets significant market needs presented by the 450,000 sudden cardiac deaths each year; many were patients for whom ablation …
