BACKGROUND: Few telesurgery studies assess the impact of latency on user experience, low latencies are often not studied despite evidence of negative effects, and some studies recruit inexperienced subjects instead of surgeons without evidence that latency affects both groups similarly. METHODS: Fifteen trainees and fourteen laparoscopic surgeons conducted two tasks on a laparoscopy home-trainer at six latencies below 200 milliseconds (ms). Completion time and usability (perceived awareness of latency, inefficiency, disturbance, adaptability, and impact on patient safety) were measured...

As surgical assist robots begin to widely spread in surgery, active developments are performed all over the world. This article surveys current developments of surgical assist robots. Especially, we focus on the surgical assist robots for minimally invasive surgery, since the surgery has been promoted worldwide. Moreover, the applications of surgical assistant robots, which help performing surgery beside surgeons, are promoted. By examining currently used robots, future developments are expected, for example, making forceps diameter smaller, downsizing the system, suitable systems for long-distance telesurgery, haptic feedback to guide the surgeon, systems for single port surgery, autonomous operation of some tasks in surgery and intelligent systems integrated diagnosis and treatments...

Since the first telegraphic transmission of an electrocardiogram in 1906, technological developments have allowed telemedicine to flourish. It has become a multi-billion pound industry encompassing many areas of medical practice and education. Telemedicine is now widely used in surgery from performing operations to teaching and can be divided into three main components; telesurgery, telementoring and teleconsultation. Developments across these fields have led to remarkable achievements such as intercontinental telesurgery and telementoring...

INTRODUCTION: Using an endoscopic telesurgical robot system (ETSRS), the authors propose a strategy for improving the safety of telesurgery by restricting the movement of an end-effector within a lesion. The strategy is validated by phantom model experiments. MATERIAL AND METHODS: The method focused on generation of force feedback and restriction of robotic end-effector movement of ETSRS based on a virtual wall. Collision detection and case classification procedures were used to determine whether the generation of force feedback or restricting the end-effector's movement was continued...

BACKGROUND: Novel robots have recently been developed specifically for endonasal surgery. They can deliver several thin, tentacle-like surgical instruments through a single nostril. Among the many potential advantages of such a robotic system is the prospect of telesurgery over long distances. OBJECTIVE: To describe a phantom pituitary tumor removal done by a surgeon in Nashville, Tennessee, controlling a robot located approximately 800 km away in Chapel Hill, North Carolina, the first remote telesurgery experiment involving tentacle-like concentric tube manipulators...

Robotic surgery was initially developed to overcome problems faced during conventional laparoscopic surgeries and to perform telesurgery at distant locations. It has now established itself as the epitome of minimally invasive surgery (MIS). It is one of the most significant advances in MIS in recent years and is considered by many as a revolutionary technology, capable of influencing the future of surgery. After its introduction to urology, robotic surgery has redefined the management of urological malignancies...

Robotic surgery is being used widely due to its various benefits that includes reduced patient trauma and increased dexterity and ergonomics for the operating surgeon. Making the whole or part of the surgical procedure autonomous increases patient safety and will enable the robotic surgery platform to be used in telesurgery. In this work, an Electrosurgery procedure that involves tissue compression and application of heat such as the coaptic vessel closure has been automated. A MIMO nonlinear model characterizing the tissue stiffness and conductance under compression was feedback linearized and tuned PID controllers were used to control the system to achieve both the displacement and temperature constraints...

Given that e-health (including telehealth) is an opportunity cost (i.e., redirecting already scarce healthcare resources away from more traditional healthcare delivery needs), performing needs assessment ensures that investment of resources in e-health is appropriate. Yet the current literature shows research is on clever, narrow, or 'one disease' telehealth applications (e.g., telediabetes; telesurgery), or creation of electronic records (e.g., EHR's; EMRs; HIS's) and accumulation of 'big data' (e.g. biosurveillance)...

BACKGROUND: Haptic feedback is of critical importance in surgical tasks. However, conventional surgical robots do not provide haptic feedback to surgeons during surgery. Thus, in this study, a combined tactile and kinesthetic feedback system was developed to provide haptic feedback to surgeons during robotic surgery. METHODS: To assess haptic feasibility, the effects of two types of haptic feedback were examined empirically - kinesthetic and tactile feedback - to measure object-pulling force with a telesurgery robotics system at two desired pulling forces (1 N and 2 N)...

BACKGROUND: The effect of telesurgical training was evaluated at two latency levels. METHODS: Eleven subjects were randomly assigned to two delay groups (400 and 600 ms). Each group trained with latency on a simple task of dV-Trainer® and performed a difficult task before (pre-test) and after (post-test) the training. The follow-up was conducted 1 week after the training. RESULTS: The difficulty decreased gradually during training for both groups, while the task completion time and the instrument motion improved only in the 600 ms group...

We seek to provide a background of the current state of pediatric urologic surgery including a brief history, procedural outcomes, cost considerations, future directions, and the state of robotic surgery in India. Pediatric robotic urology has been shown to be safe and effective in cases ranging from pyeloplasty to bladder augmentation with continent urinary diversion. Complication rates are in line with other methods of performing the same procedures. The cost of robotic surgery continues to decrease, but setting up pediatric robotic urology programs can be costly in terms of both monetary investment and the training of robotic surgeons...

BACKGROUND: Despite the growing incidence of cancer worldwide, there are an insufficient number of primary care physicians, community oncologists, and surgeons to meet the demand for cancer care, especially in rural and other medically underserved areas. Teleoncology, including diagnostics, treatment, and supportive care, has the potential to enhance access to cancer care and to improve clinician education and training. OBJECTIVES: Major cancer centers such as The University of Texas MD Anderson Cancer Center must determine how teleoncology will be used as part of strategic planning for the future...

Despite the great diversity of teleoperator designs and applications, their underlying control systems have many similarities. These similarities can be exploited to enable inter-operability between heterogeneous systems. We have developed a network data specification, the Interoperable Telerobotics Protocol, that can be used for Internet based control of a wide range of teleoperators. In this work we test interoperable telerobotics on the global Internet, focusing on the telesurgery application domain. Fourteen globally dispersed telerobotic master and slave systems were connected in thirty trials in one twenty four hour period...

BACKGROUND: The primary limitation of telesurgery is the communication latency. Accurate and detailed data are lacking to reveal the latency effects on surgical performance; furthermore, the maximum acceptable latency in telesurgery remains unclear. METHODS: Sixteen medical students performed an energy dissection exercise and a needle-driving exercise on the robotic simulator dV-Trainer(®), and latencies varying between 0 and 1,000 ms with a 100-ms interval were randomly and blindly presented...

OBJECT: Robotic surgery can be applied as a novel technology. Our master-slave microscopic-micromanipulator system (NeuRobot), which has a rigid endoscope and three robot-arms, has been developed to perform neurosurgical procedures, and employed successfully in some clinical cases. Although the master and slave parts of NeuRobot are directly connected by wire, it is possible to separate each part and to apply it to telesurgery with some modifications. To evaluate feasibility of NeuRobot in telesurgery, some basic experiments were performed...

Surgery has increasingly become a technology-driven specialty. Robotic assistance is considered one innovation within abdominal surgery over the past decade that has the potential to compensate for the drawbacks of conventional laparoscopy. The dramatic evolution of robotic surgery over the past 10 years is likely to be eclipsed by even greater advances over the next decade. We review the current status of robotic technology in surgery. The Medline database was searched for the terms "robotic surgery, telesurgery, and laparoscopy...
