Abstract Background With increasing research on system integration for image‐guided therapy (IGT), there has been a strong demand standardized communication among devices and software to share data such as target positions, images device status. Method We propose new, open, simple extensible network protocol IGT, named OpenIGTLink, transfer transform, image status messages. conducted performance tests use‐case evaluations in five clinical engineering scenarios. Results The was able position...
Worldwide, over 50 million people suffer from persistent hand impairments after stroke or spinal cord injury (SCI). This results in major loss of independence and quality life. Robotic exoskeletons can compensate for lost motor function assist grasping tasks performed everyday activities. Several recent prototypes partially provide this assistance. However, it remains challenging to integrate the dexterity required daily a safe user-friendly design that is acceptable use subjects with...
In this paper, a new hand exoskeleton device using three-layered sliding spring mechanism is presented. contrast to state of the art mechanisms (typically link, wire or pneumatically driven), proposed driven through large deformations compliant body. The can be made compact and lightweight by adequately positioning elements. addition, designed distribute 1-DOF actuated linear motion into three rotational motions finger joints, which translate natural flexion/extension. primary application...
Enabling individuals who are living with reduced mobility of the hand to utilize portable exoskeletons at home has potential deliver rehabilitation therapies a greater intensity and relevance activities daily living. Various exoskeleton designs have been explored in past, however, devices remained nonportable cumbersome for intended users. Here we investigate remote actuation system wearable exoskeletons, which moves weight from weakened limb shoulders, reducing burden on user improving...
Robotically assisted rehabilitation therapy, which is therapy performed using a robotic device that guides or assists motion and in some cases triggered by biological signal (such as myoelectric brain signal) effective recovering motor function following impairment. In the field of robots human support robot, exoskeleton have been widely studied both for upper lower limbs. Applying to wrist joint remains challenging because has two degrees freedom structure smaller than structures other limb...
Several robotic surgical systems have been developed for minimally-invasive surgery including commercialized products such as da Vinci and ZEUS. We a system, which had performed remote experiments four times until now (performed on pigs over 150 km in Japan). In this paper, two approaches that extend the system from perspective of extensions surgeon's dexterity are described. The first approach is development complex forceps, multiple d.o.f. their tip. A rigid link mechanism has applied to...
Early-stage gastrointestinal cancer is often treated by endoscopic submucosal dissection (ESD) using a flexible endoscope. Compared with conventional percutaneous surgery, ESD much less invasive and provides high quality of life for the patient because it does not require skin incision, organ preserved. However, operator must be highly skilled requires endoscope energy devices, which have limited degrees freedom. To facilitate easier manipulation these we developed surgical robot comprising...
This paper describes a tele-endoscopic surgical system with force feedback capability. The consists of multi-media cockpit, site and communication link. multimedia cockpit is equipped type master manipulators, visual auditory information presentation apparatuses, foot switches. A slave manipulator 3 arms located at the site; left right hold forceps or radio knife center arm holds an endoscope. has special safety mechanism. Vital signs can be also transmitted to cockpit. In experiment,...
The rubber hand illusion is a well-known multisensory illusion. In brief, watching being stroked by paintbrush while one's own unseen synchronously causes the to be attributed body and "feel like it's my hand." thought triggered synchronized tactile stimulation of both subject's fake hand. To extend conventional illusion, we introduce robotic technology in form master-slave telemanipulator. developed one degree-of-freedom system consists an exoskeleton master equipped with optical encoder...
Minimally Invasive Surgery (MIS) is one of the most successful applications surgical robots. Although introduction robotic technology has brought a number benefits, further advancements in MIS are limited by size and bending radius instruments. In this paper, we present compliant four degree-of-freedom manipulator that consists elastic elements with partly thinner structures. The proposed mechanism allows element to deform locally, thus minimizing its while low mechanical parts greatly...
Robotic prostheses are expected to allow amputees greater freedom and mobility. However, available options control transhumeral reduced with increasing amputation level. In addition, for electromyography-based of prostheses, the residual muscles alone cannot generate sufficiently different signals accurate distal arm function. Thus, controlling a multi-degree (DoF) prosthesis is challenging currently techniques. this paper, an electroencephalogram (EEG)-based hierarchical two-stage approach...
Brain–computer interfaces are emerging as an important research area and intended to create understanding between a computer the human brain ensure that robot–human interactions become more intuitive user-friendly. However, encoding of information derive motion user in real time continues present problem with respect control wearable robots multiple degrees freedom. In this study, new approach several freedom robot is proposed its feasibility studied by estimating user’s intention time,...
In recent years, robotic technology has been introduced to medical fields and many surgical robots have presented not only in academic but also as commercialized products. this paper, an outer shell type 2 DOF bending manipulator using a spring-link mechanism is presented. The was developed for robot, which can implement various treatment devices inside of the manipulator. simple combination flat spring rigid link with passive joint connection. composed by four mechanisms. most unique...
<b>Background and study aims: </b>The conventional procedure of endoscopic submucosal dissection (ESD) is technically demanding. This investigated the efficiency novel articulating devices (maximum diameter 2.6 mm), which can be used with commercially available, standard endoscopes. <b>Patients methods: </b>In an ex vivo comparative study, eight endoscopists were divided into novices experienced operators, performed ESD using new setup. An in animal experiment was by two experts. Procedure...
For a laparoscopic surgery, master-slave type surgery assisting systems have been developed. It is expected that introducing force feedback for the system improves operability. However, measurement of grasping or reacting forceps difficult, in particular, case bending forceps. Therefore, paper, method to calculate applying on tip proposed by measuring driving shafts link-type two directional Furthermore, compensation influence friction also described and experiments has conducted validate...
