This paper is concerned with recent development in robot assisted radiotherapy for lung tumors. The paper first analyzes technical challenges regarding tumor position determination and prediction, by invasive and non-invasive methods, correlation models of the tumor motion and the respiratory signals, as well as modeling and control of the robot manipulator. Several currently available solutions and...
In this paper, we present a medical robot calibration system necessary for total knee arthroplasty. The system includes several processes such as robot manipulator/tool calibration to check robot's accuracy, the object matching which finds a relationship about affected part information between in the system and real environment, and the additional processes alike robot offline programming. In case...
Due to the merit of stabilization and precision, robot is imported in the surgery operations of abdominal cavity, thoracic cavity etc. In order to strengthen the advantage of the minimally invasive surgical robot, the research is focused on the trajectory planning of the 6-DOF manipulator of the robot. The algorithm of the manipulator trajectory planning is proposed, and the curved track of the manipulator...
This paper studies a control method for the manipulator of an automatic cryogenic storing vessel which can improve a ratio of survival of a cord blood. The cord blood keeps in liquid nitrogen in the cryogenic vessel. The integrated robot control system for storing a cord blood based on mechanism of SCARA robot is developed. The system consists of a cryogenic vessel, a robot arm controller using a...
Heart failure resulting from myocardial infarct, oxygen-deprived tissue death, is a serious disease that affects over 20 million patients in the world. The precise injection of tissue-engineered materials into the infarct site is emerging as a treatment strategy to improve cardiac function for patients with heart failure. We have developed a novel miniature robotic device (HeartLander) that can act...
This paper presents the design criteria of a robot manipulator for the rehabilitation of the upper limb. The machine is conceived to optimize the dynamic behavior in the interaction with the patient, basically in terms of low impedance when back-driven and low and isotropic inertial properties. Robot kinematics and dynamics are mathematically modeled and its dynamic properties are measured in the...
Application of robotics in the field of medical has gained a strong footing apart from manufacturing industries, sheep-shearing, agriculture, nuclear power industries, fire-fighting, mining, underseas applications, outerspace and other application. In the present work Dynamic equation of motions of a robot arm are considered using Lagrangian-Euler formulation and programs in C, C++ and MATLAB are...
Angioplasty is a minimally invasive procedure wherein a catheter (a thermoplastic hollow wire) is inserted into the femoral artery and guided till it reaches a blockage in the blood vessel. There could be some potential complications arising from the conventional way of performing angioplasty, e.g., damage to the blood vessel due to excessive force of insertion and exposure of clinicians to harmful...
In this paper, an intelligent bed robot system (IBRS) is proposed, that is a special bed equipped with robot manipulator. To assist a patient using IBRS, pose and motion estimation process is fundamental. It is designed to help the elderly and the disabled for their independent life in bed without other assistants
