______________________________________________________________________________________ Introduction and objective: Radical prostatectomy is a first-line treatment for localized prostate cancer. However, in some cases, biochemical recurrence associated with imaging-detected nodal metastases may happen. Herein, we aim to present the surgical technique for salvage lymph node dissection after radic...

In this manuscript, the reliability of a robotic system has been analyzed using the available data (containing vagueness, uncertainty, etc). Quantification of involved uncertainties is done through data fuzzification using triangular fuzzy numbers with known spreads as suggested by system experts. With fuzzified data, if the existing fuzzy lambda–tau (FLT) technique is employed, then the comput...

flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biologicalinsects and useful for a wide range of tasks, including exploration, environmental monitoring, searchand rescue, and surveillance. recently, robotic insects driven by piezoelectric actuators have achievedthe important goal of taking off with external power; however, fully autonomous operation requir...

Continuum robotic arms that are inspired from nature, have many advantages compared to traditional robots, which motivate researchers in this field. Dynamic modeling and controlling these robots are challenging subjects due to complicated nonlinearities and considerable uncertainties existing in these structures. In this paper, first a dynamic three-dimensional model of the continuum robotic ar...

Embedded systems are one of the sub-branches electrical and electronics engineering, but also used in many service areas today. systems, which almost common point Electronics software fields, preferred primarily by people these fields. For programming embedded support different electronic cards computers is needed. With development both hardware components languages, have begun to be all engine...

BACKGROUND Most sample preparation methods characteristically involve intensive and repetitive labor, which is inefficient when preparing large numbers of samples from population-scale studies. METHODS This study presents a robotic system designed to meet the sampling requirements for large population-scale studies. Using this robotic system, we developed and validated a method to simultaneou...

recent developments in the area of smart structures indicate that variable geometry / stiffness truss network is of fundamental importance in designing smart transformable structures and systems for space applications. this paper presents the conceptual design and dynamic modeling of a cooperative re-configurabel dual-arm robotic structure called dual-arm cam-lock manipulator. the manipulator i...

Cadaveric in vitro studies are essential to test hypotheses concerning surgical manipulations in the same individual. Robotic technologies as well as different knee-models have been developed to get an in-depth comprehension of knee joint kinematics. The purpose of this study was to compare utilization of these different established principles.Ten human cadaveric knee specimens were used to mea...

The gold standard treatment of degenerative mitral valve disease remains surgical repair. The classic repair described by Dr. Carpentier (1) with leaflet resection and annuloplasty remains the primary technique for mitral repair. Other techniques such as the “American correction” (2) or artificial chordae have been introduced with similar success rates. Innovations in surgical approach over the...
