Resumen

Nurses who provide care in robotic surgery must have sufficient special training in the operation of the da Vinci robot to perform their roles with knowledge and confidence that can yield optimal patient outcomes. The local nursing practice problem in the project facility, and the focus of this doctoral project, was the lack of an evidenced-based robotics education program for registered nurses who participate in robotic surgery. The gap in practice was nurses' lack of knowledge, which interfered with the care provided to the robotic surgical population. The purpose of this project was to deve

Whole-cell patch clamp electrophysiology of neurons in vivo enables the recording of electrical events in cells with great precision, and supports a wide diversity of morphological and molecular analysis experiments important for the understanding of single-cell and network functions in the intact brain. However, high levels of skill are required in order to perform in vivo patching, and the process is time-consuming and painstaking. Robotic systems for in vivo patching would not only empower a great number of neuroscientists to perform such experiments, but would also open up fundamentally ne

Resumen

Increasingly, diagnosis of cardiac disease, relies on computer processing of images to aid decision making. In this thesis, we use echocardiography, which is the most widely used cardiac imaging modality to study the motion of the left ventricle. Currently, clinical reporting of echocardiography examinations is operator-dependent and largely qualitative. Commercially available software does not track the left ven- tricle. Also, it does not provide quantification of regional function. This thesis establishes a framework for the quantitative regional analysis of left ven- tricular function. The

Thesis (MScEng)--Stellenbosch University, 2009.<br>ENGLISH ABSTRACT: Minimal invasive surgery (MIS) enables surgeons to operate through a few small incisions made in the patient’s body. Through these incisions, long rigid instruments are inserted into the body and manipulated to perform the necessary surgical tasks. Conventional instruments, however, are constrained by having only five degrees of freedom (DOF), as well as having scaled and mirrored movements, thereby limiting the surgeon’s dexterity. Surgeons are also deprived of depth perception and hand-eye coordination due to only having tw

Nasopharyngeal carcinoma (NPC) is the 7th commonest cancer in Hong Kong. Improvements in radiotherapy had increased the cure. Unfortunately, up to 10% of the patient still suffered from local recurrence. Because of the deep location, nasopharyngectomy was considered a difficult operation. Developments in surgical approaches had now established nasopharyngectomy as a standard salvage for locally recurrent NPC.

Resumen

This work describes a self-sensing technique for a piezoelectrically driven MRI-compatible tweezer style end effector, suitable for robot assisted, MRI guided surgery. Nested strain amplification mechanisms are used to amplify the displacement of the piezo actuators to practical levels for robotics. By using a hysteretic piezoelectric model and a two port network model for the compliant nested strain amplifiers, it is shown that force and displacement at the tweezer tip can be estimated if the input voltage and charge are measured. One piezo unit is used simultaneously as a sensor and an actua

This work focuses on the use of 3D motion capture data to create and optimize a robotic human body model (RHBM) to predict the inverse kinematics of the upper body. The RHBM is a 25 degrees of freedom (DoFs) upper body model with subject specific kinematic parameters. The model was developed to predict the inverse kinematics of the upper body in the simulation of a virtual person, including persons with functional limitations such as a transradial or transhumeral amputation. Motion data were collected from 14 subjects: 10 non-amputees control subjects, 1 person with a transradial amputation, a

Resumen

Biological systems are able to perform complex movements with high energy-efficiency and, in general, can adapt to environmental changes more elegantly than traditionally engineered mechanical systems. The Equilibrium Point Hypothesis describes animal motor control as trajectories of equilibrium joint angle and joint stiffness. Traditional approaches to robot design are unable to implement this control scheme because they lack joint actuation methods that can control mechanical stiffness, and, in general, they are unable to take advantage of energy introduced into the system by the environmen

Robot is a machine with a human-like behavior which partially or completely fulfills human function when interacting with the surrounding world. Robots are divided into three types: robots with the specific program of actions, operator-controlled robots and artificial intelligence robots. No doubt, that the development of new technologies had a great impact on medicine. At present, doctors can perform operations, which seemed impossible ten years ago.

Resumen

Sepsis is a life-threatening syndrome that occurs due to dysregulated body response to pathogenic infections. More than 30 million cases are recorded annually worldwide, with a high mortality rate of up to 40% of the recorded cases. Early diagnosis of sepsis will help clinicians to start proper therapy as early as possible and save lives. Circulating miRNAs in biofluids were found previously as potential biomarkers that can be used in a multi-marker panel to develop a rapid, friendly user diagnostic kit for the early sepsis diagnosis. This study assessed miRNAs from healthy donors’ human plasm

Resumen

There are many clinical situations where magnetic resonance imaging (MRI) is preferable over other imaging modalities, while the major disadvantage is the relatively long scan time. Due to limited resources, this means that not all patients can be offered an MRI scan, even though it could provide crucial information. It can even be deemed unsafe for a critically ill patient to undergo the examination. In MRI, there is a trade-off between resolution, signal-to-noise ratio (SNR) and the time spent gathering data. When time is of utmost importance, we seek other methods to increase the resolution

Resumen

In the time-lapse of hundreds of millions of years, living organisms have continuously evolved, developing a myriad of astonishing forms and abilities to be often inspirational for mankind. In 1997, Janine Benyus, paved the onset of a revolutionary discipline called biomimicry. Biomimicry can be elegantly defined as “innovation inspired by nature”. From a practical point of view, it is an approach to innovation that aims to solve human challenges by emulating nature’s time-tested strategies. A range of technological improvements have been inspired by terrestrial life and examples of biomimic

Resumen

La telechirurgia è una tecnica operatoria che permette al medico di eseguire interventi chirurgici su pazienti fisicamente distanti. Il chirurgo esegue l’intervento mediante un sistema robotico con abilità chirurgiche eccezionali, combinato con tecnologie di comunicazione che consentono lo scambio di dati tra le postazioni e l’ausilio di un monitor per il controllo continuo del campo operatorio. In questo lavoro sono analizzati due interventi chirurgici a distanza, con particolare attenzione alle principali strumentazioni e reti telematiche utilizzate. Il primo intervento chirurgico a distanz

Resumen

Having a device with the capability of measure motions from gait produced by a human being, could be of most importance in medicine and sports. Physicians or researchers could measure and analyse key features of a person's gait for the purpose of rehabilitation or science, regarding neurological disabilities. Also in sports, professionals and hobbyists could use such a device for improving their technique or prevent injuries when performing. In this master thesis, I present the research of what technology is capable of today, regarding gait analysis devices. The research that was done has then

Resumen

Physical therapy is a field with ever increasing demands as the population ages, resulting in a larger number of individuals living with impairments. Therapy is both physically intensive and time intensive for physical therapists, and can require more than one therapist per patient. The use of technology can reduce both these physical and time demands if appropriately applied, while improving repeatability and providing quantitative evaluation of performance. Through these abilities, it may also improve the quality of life for patients. The work presented here explores how the mechanical and c
