Tele-echography may be an interesting alternative to conventional care when the medical expert is not close to the patient to be examined. In a system for tele-echography, medical expert proprioception and gesture feelings must be preserved to synchronize the ultrasound images with the motion made by the physician. It is why we develop a master-slave system for robotic tele-echography integrati...

By analyzing the characteristics and applications of robotic at locally and abroad, specifies the importance of force feedback technology in the robotic system and describes the current development process of force feedback technology. The methods, design and implementation of the master/slave prototype surgical system along with force feedback facility are introduced. The basic materials is al...

BACKGROUND We introduce the first robotic ultrasound-guided prostate intervention device and evaluate its safety, accuracy and repeatability. METHODS The robotic positioning system (RPS) determines a target's x, y and z axes. It is situated with a biplane ultrasound probe on a mobile horizontal platform. The integrated software acquires ultrasound images for three-dimensional (3D) modelling, ...

The work presented in this paper is related to the use of a haptic device in an environment of robotic simulation. Such device introduces a new approach to feel and to understand the boundaries of the workspace of mechanisms as well as its kinetostatic properties. Indeed, these concepts are abstract and thus often difficult to understand for the end-users. To catch his attention, we propose to ...

This paper presents a method to determine trajectory for robot that involves a close interaction between robotic systems and human beings.The proposed method considers robot trajectory as path in operational space and time rhythm distinct problems verifying the natural smoothness of voluntary human movement. Operational space path is determined experimentally as individual movement pattern. The...

OBJECTIVE This article describes the effect of a robotic device combined with repetitive-task practice (RTP) on upper-extremity function in a patient with chronic stroke. METHOD The client was a 32-year-old woman, 11 months after stroke, with minimal wrist and finger movement. She received approximately 48 hr of intervention split evenly between a robotic device (Hand Mentor) and RTP during 3...

BACKGROUND The Flex Robotic System is a new robotic device specifically developed for transoral robotic surgery (TORS). METHODS We performed a prospective clinical study, assessing the safety and efficacy of the Medrobotics Flex Robotic System. A total of 40 patients required a surgical procedure for benign lesions (n = 30) or T1 and T2 carcinomas (n = 10). Access and visualization of differe...

This paper presents a locomotion control implementation of a robotic system mimicking the undulating fins of fish. To mimic the actual flexible fin of a real fish, we created a ribbon fin type actuation device with a series of connecting linkages and attached it to the robotic fish. By virtue of a specially designed strip with a slider, each link is able to turn and slide with respect to the ad...

INTRODUCTION Robotic technology has been safely integrated into thoracic and abdominopelvic surgery, and the early experience has been very promising with very rare complications related to robotic device failure. Recently, several reports have documented the technical feasibility of transoral robotic surgery (TORS) with the daVinci Surgical System. Proposed pharyngeal and laryngeal application...
