This paper presents a new robotic mechanism for ultrasound imaging. The device is placed on a patient's body by an operator, and an ultrasound expert controls the motions of the device to obtain ultrasound images. The paper focuses on the robotic mechanism that performs ultrasound imaging. The design of the mechanism is based on two approaches to produce center of motion for an ultrasound probe...

There are many tactile devices for indentation examinations to measure mechanical properties of tissue. The purpose of this paper is to develop a portable indentation robotic device to show its usability for measuring the mechanical properties of a healthy abdominal tissue. These measurements will help to develop suitable mathematical models representing abdominal tissue. A 1-DOF portable robot...

Systems and methods for robotic transport are disclosed herein. In some embodiments, robotic systems for transporting biological samples include: a plurality of capillary vessels, in which each capillary vessel can contain a biological sample from a population; a receptacle that can contain the plurality of capillary vessels; a centrifuge; a first robotic device that can transport the receptacl...

results twelve original studies fulfilled the inclusion criteria. the current literature suggests that the learning curve of robotic rectal surgery varies between 15 and 44 cases and is probably shorter to that of laparoscopic rectal surgery. conclusions there are only a few studies assessing the learning curve of robotic rectal surgery and they possess several differences in methodology and ou...

BACKGROUND AND PURPOSE Robotic devices that provide passive guidance and stabilization of the legs and trunk during treadmill stepping may increase the delivery of locomotor training to subjects with neurological injury. Lower-extremity guidance also may reduce voluntary muscle activity as compared with compliant assistance provided by therapists. The purpose of this study was to investigate di...

Radiofrequency Ablation (RFA) assisted liver resection results in lesser blood loss during liver resections. It involves a time consuming and error prone process of alternating coagulation and cutting until the line of transaction is completed to finally divide the liver. We proposed a new robotic mechanism to automate the ablation and division process. The robotic device comprises a 2link mani...

Traditional, hospital-based stroke rehabilitation can be labor-intensive and expensive. Furthermore, outcomes from rehabilitation are inconsistent across individuals and recovery is hard to predict. Given these uncertainties, numerous technological approaches have been tested in an effort to improve rehabilitation outcomes and reduce the cost of stroke rehabilitation. These techniques include b...
