Vascular interventional surgery is the most common method for treatment of cardiovascular diseases. Interventional surgical robot has attracted extensive attention because its precise control and remote operation. However, conventional force sensors in robots can only detect axial thrust pressure catheter. Inspired by function insect antennae, we designed a structure with thin-film sensing devi...

Abstract To meet the requirements of large tolerance, high precision, soft capture and reliability space gripper, a three finger end effector is developed. The gripper adopts fingered configuration, which needs to be used together with corresponding adapter. It characterized by stable grip, clamping force, tolerance strong correction ability. A 6-DOF microgravity equivalent device innovatively ...

Upper and lower bounds for the eigenvalues of three types of matrices M are established. If M is written as the sum of a diagonal matrix D plus a matrix A, the real parts of the eigenvalues of M must lie between the real parts of the neighboring diagonal elements of D, no matter how large the elements of A or how closely spaced the diagonal elements of D. One of the types—that representing one ...

Background & aim: Based on the current scientific evidence, delayed cord clamping (DCC) elevates early hemoglobin concentrations and iron stores in the neonate. However, the persistent practice of early cord clamping (ECC) is still a routine care. The aim of the present study was to investigate the umbilical cord clamping practices of maternity care providers in Oman. Methods: This cross-sectio...

In this article, we propose a new control approach for the twisted string actuation system; hybrid scheme consisting of two nested loops, considering motor angle and axial force at clamping point actuator as system outputs. We show that measuring base actuator, can effectively estimate compensate coupling torque between external load. Then, compensation allows formulating linear law to angular ...

BACKGROUND In this study, the authors investigated changes in Bispectral Index (BIS) values and plasma propofol concentrations (Cp) after aortic cross clamping in the descending thoracic aortic aneurysm repair surgery during propofol anesthesia. METHODS Prospectively, in 10 patients undergoing thoracic aortic surgery during total intravenous anesthesia with propofol, BIS values were recorded ...

Securing human safety in a physical human–robot interaction (pHRI) has been extensively studied to allow for the expansion of robotic applications. Dummies with same impedance properties as those soft tissues are suitable substitutes validation assurance pHRI experiment. This study demonstrated development process dummies high biofidelity. A psychophysiological experiment was designed replicate...

A fuzzy-logic controller supporting the manufacturing of wind turbines and the bolt tightening of their hubs has been designed. The controller embeds assembly error recognition capability and detects tightening faults like misalignment, different threads, cross threads and wrong or small nuts. According to this capability, K-nearest classifiers have been implemented to cluster the output contro...
