INTRODUCTION

1.1 PROJECT BACKGROUND

The development involving artificial organs and implants for replacing the injured and diseased hard tissues like bones, teeth and joints is highly desired in orthopaedic and surgery. In the past few decades, increase in the utilization associated with self-operating machines, participation of many persons in sports, defence activities, increased interest in motorcycles and bicycles, and day-to-day increasing traffic, has resulted in enormous increase in the number of accidents. This has necessarily led people to opt for orthopaedic implants for early and speedy recovery and resumption of their routine activities. The value of the global orthopaedic implant market including spinal, joint …show more content…
The material selective is depend on the part of the implantation. Materials that are selectively used in orthopaedics are ceramics, polymers and metals and alloys. Usually, orthopaedic implants are created from various metal alloys. The common medical metal materials containing the titanium and its alloys, Co–Cr alloy, stainless steel and others have been applied in SLM made implants. Cobalt-chrome or cobalt-chromium (CoCr) is a Cobalt-based alloy containing Cr and Mo has been used for implantation owing to their excellent mechanical and tribological properties. This study therefore aims to evaluate the physical properties for open cellular structure cobalt chromium molybdenum (CoCrMo) alloy fabricated by selective laser melting. The engineering objective is to provide minimal physiological stress to the remaining bone system so that the integrity and functionality of the bone and prosthetic materials are maintained over a long service …show more content…
Corrosion is one of the major processes affecting the life and service of orthopaedic devices made of metals and alloys. Implants can fail when the artificial implant loosen during typical in-service lifetimes of 15 years due to this corrosion. So, it is important approach is to develop biocompatible and corrosion resistant metallic materials to diminish or avoid adverse body reaction.

Products Liability

...hospitals as well as mending cuts and scrapes that people get, targeting kids because they are accident prone. In later years Johnson & Johnson explored other opportunities mainly in the over-the-counter medicinal products. Over the years they have been subject to many lawsuits but the one this paper will focus on is the product liability lawsuit on the DePuy ASR hip implant. DePuy is a company that specializes in orthopedic products and was acquired by Johnson & Johnson in 1998. The metal on metal hip replacement DePuy ASR was approved by the FDA for use by surgeons on patients that were in need of a hip replacement in 2005. (Meier, 2010). The DePuy ASR hip replacement should have a life of at least 10 years. The device was being used on patients, soon after the DePuy dividion of Johnson & Johnson started receiving complaints of the device with the largest spike of complaints in 2009. (Meier, 2010). Many of the complaints resulted in the patient having to receive another hip replacement only a few years after receiving their first hip replacement. The reason the DePuy ASR hip implant didn’t last is because the device is metal on metal and can cause metal debris as the hip is used. ‘This can cause damage to muscles and other soft tissues which results in the replacement of the device.’ (Meier, 2010). The device was tested on a few patients who were not aware they were ‘testing’ and the...

Bionics

...Chapter 1 INTRODUCTION Bionics (also known as biomimetics, biognosis, biomimicry, or bionical creativity engineering) is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. The word "bionic" was coined by Jack E. Steele in 1958, possibly originating from the Greek word "βίον", pronounced "bion", meaning "unit of life" and the suffix -ic, meaning "like" or "in the manner of", hence "like life". Some explain the word as being formed from "biology" + "electronics". We are entering a new era of technology inspired by lifestyle and healthcare.  The human body is a significant application area for technology and, under the research theme of bionics, we are applying the techniques and understanding of engineering to applications which will improve human health.  Our research group is a multi-disciplinary team of engineers, clinicians and biochemists, interfacing engineering technologies to biological systems to improve chronic disease management. The team is developing biomedical platforms based on established techniques and leveraging on semiconductor technology to produce a new breed of medical devices. Such examples include silicon β-cells in a bionic pancreas for diabetics, ultra low power solid-state bio/chemical sensors for continuous monitoring, advanced microfluidics for lab-on-chip technologies, neural monitoring and stimulation to enable future diagnostic/monitoring tools, in addition...

Biomedical Engineering and Physics

...John Smith Dr. Madaro University Physics I Spring 2014 Biomedical Engineering and the Future of Modern Medicine I have always been interested in math and science, but my interest developed into a fascination this year in physics class. I enjoyed being able to apply all of the laws and theories that we learned in class to real-world situations. I liked being able to figure out the distance an object traveled just by knowing the acceleration and speed, finding the vertical and horizontal components of a force, and solving for the coefficient of friction of a surface. I loved that every concept seemed to build on the one before it, and how they all helped me understand the world in a way I never had before. Whenever I think about my future, what I want to study, and how I want to make a living, I always think of engineering- a career that would allow me to develop this fascination with the way the world works and to apply my knowledge to a project that could help improve peoples' lives. I want to go into this field to develop technology that could help cure disease or improve the quality of life of those with serious medical conditions. The concepts of Physics play a crucial part in the everyday work of Biomedical Engineers, specifically in the invention of prosthetic limbs, artificial organs, and improved hearing aids. "The first artificial limbs were stiff and did not have joints that bent like real arms, hands, or legs" (Woods 40). The invention of the artificial limbs...

Cybernetic Implants

...Cybernetic Implants One of the things that we will probably being seeing in the future is the development of cybernetic implants. There are a few pros and cons to the development of cybernetic implants. Some of the pros could be increased life span do to less illness, increased economy due to the sales of implants, increased productivity due to increased physical strength, increased security due to most everything financial would be implanted into you so less identity theft, and increased technology due to increased portions of the brain being unlocked from neural enhancements. Some of the cons could be issues such as the religious views on such things. Some religions believe that the use of cybernetic implants for financial transactions to be a form of the mark of the beast and would have no part in such implants. This issue alone could start major riots and divisions in certain states. Another issue could result from the physical enhancement side. There will probably be an increase in crimes such as grand theft auto due to people having increased strength and in essence feeling almost godlike. They will probably be more likely to ignore the laws and think that they are above them. This will also cause those who cannot afford such implants to be at increased risk. The neural enhancements could also cause people to be able to outthink many security systems and be able to develop more homemade devices for crime. There is a lot consider when dealing with cybernetic implants. While...

Dental Implant Failure Research Paper

...Potential Implant Failure Posted on February 23, 2016 by admin in Uncategorized How do you tell that your dental implant is failing? “It is failing if it is loose” is the answer most likely to be given by many people. However, while a loose implant is likely to fail, that isn’t the only symptom you should watch out for. Other signs that your implant isn’t likely to integrate or heal properly include: Discomfort Discomfort and pain are some of the first signs that something is wrong with your body. Therefore, pain and discomfort around your dental implant should send you to the dentist. The only exception is if your implant is a recent one, and you are experiencing post-surgical pain associated with healing. However, if you are already done with this early pain, and this is a new one, you may be dealing with something a bit more serious, such as peri-implantitis. This is a bacterial attack around the implant, and it is one of the most...

Dedination and More Detailed Story About Fm

...One study compared fixed and Dynamic FM performance for hearing aid users, while the other made the same comparison with cochlear implant recipients. In the hearing aid study, conducted by Dr. Linda Thibodeau, both adults and children (ages 11 tol5) were used as subjects, and both objective and subjective measures were taken. The objective comparisons were conducted in a large classroom, with the interfering noises - ranging from 54 dB to 80 dB - emanating from four speakers located in the corners of the room. The FM microphone was placed six inches from another loudspeaker located in the center of the room. The goal was to create a situation where someone would talk into an FM microphone while the listener was surrounded by changing levels of ambient noises. For the subjective comparisons, the subjects tried both the fixed and the adaptive systems at home and during activities in a public aquarium. As expected, the objective results show no difference between the two systems at low noise levels. This is because the adaptive feature is not triggered until the background noise level exceeds 57 dB. But as the noise level increased, the speech perception scores increased with the adaptive system only, reaching a maximum difference of about 50 percent at the higher noise levels. Across all noise levels, the average difference between the fixed and the adaptive systems was about 25 percent. Subjectively, too, most or all (depending upon the activity) of the subjects preferred the...

Dental Implant Informative Speech

...Even with good oral health practices like regular brushing, flossing and dental visits, tooth loss can occur. The good news is that if you lose a tooth to decay, gum disease or an injury, you can now get an implant which will look just like your natural tooth. Dentist Thad Kawakami-Wong of AAWindward Dental Group offers advice on getting dental implants. Understanding Implants A dental implant is a replacement for a tooth root. When you lose a tooth, the root is often damaged. An implant replaces the root with a synthetic root, usually made of titanium, to which a replacement tooth can be attached. The dentist places the implant into the socket in the jawbone that is left by the root that has been damaged. The jawbone will heal around...

Microchip Implants in Humans

...Microchip Implants in Humans. A technology I have been interested in has been the microchip implant. This is a transponder encased in silicate encased in silicate glass and implanted in the body. These typically contain a unique ID number that can be lined to the information contained in an external database, such as personal identification, medical history, and medications. This advance in technology can help with GPS tracking on a human. If a child was lost or abducted this chip could be tracked and potentially save the child’s life. Someone suffering from Alzheimer’s could benefit from this. We could keep better track on criminals who disappear once released and maintain updated records on those who should be registered as offenders. People with medical conditions could benefit from the implant as well. This implant could provide health information allowing a paramedic to scan your chip and administer proper medicine. If you were to pass out or have a heart attack and were unresponsive this could save your life. There have been trials of drug-releasing microchips. The results came back successful in women who were given doses of Osteoporosis. The results were published on the website of the journal Science Translational Medicine. A major impact I believe we could benefit from the microchip would be better security. There are some companies that have been using this technology. Rather than trying to remember or keeping from passing codes, this chip allows you access...

Brain Implants

...Kevin Wang Dr. Pearce Rhetoric 102 19 March 2010 The Brain Implant Dilemma In 2002, author M.T. Anderson wrote a novel called “Feed”, with a story envisioning a future where all human beings have implanted computer chips in their brains (Anderson 2002). It would be easy to dismiss such a bold concept as a product of fiction. However, many films and books with plots set in the future have successfully predicted the invention of many current technologies that simply did not exist at the time, including flat-screen TVs (Back to the Future II), unmanned aircraft (The Terminator), and video chatting (2001: A Space Odyssey). Suffice it to say, brain implants, as these embedded computer chips are called, are projected to become a reality. The past few years have already seen the integration of computer chip and organism, with millions of cats and dogs across the world injected with identifying microchip implants underneath their skin. Brain implants have also benefitted the medical field enormously, having in some cases cured blindness (Graham-Rowe 2007) and Parkinson’s disease (Harding 2009). However, developments indicate that brain implants for personal consumer use may see the light of day. IBM, the world’s largest chipmaker, recently announced their intent to research and develop brain implants capable of controlling gadgets via brain waves by 2020 (Hsu 2009). Toyota has already successfully demoed a wheelchair that can be controlled by its rider through brain waves...

All-On-4 Procedure

...(missing teeth) or for those that have severe structural issues with their teeth due to injury, decay, or gum disease. All-on-4 provides immediate rehabilitation with a full set of teeth. All-on-4 refers to the procedure that uses dental implants on either your upper or lower jaw to replace the entire arch with a dental prosthetic. These four implants provide the support for a bridge that can hold 10 to 14 teeth. This is typically placed in the patient within 24 hours of the surgery. Much like traditional dental implants, All-on-4 uses the available bone to secure the dental prosthetic to the jaw. However, All-on-4 has the advantage of not requiring a bone graft during the procedure. Special abutments allow for the placement of your bridge immediately. Only a modified diet is required while your gums heal and the implant fuses with the bone in your child. This typically takes about six months until your final bridge is placed and you're able to resume a normal diet....

Penn Square Bank and the Down Corning Bankruptcy

...Penn Square Bank and the Down Corning Bankruptcy Today’s businesses struggle to survive in a volatile marketplace and frequently internal and external ethical pressures are placed upon employees and management in an effort to ensure the success of the company. Companies like Penn Square Bank faced ethical pressures regarding documentation, credit extension, and revenue recognition, which eventually led to the closing of Penn Square Bank. The Dow Corning bankruptcy raised many ethical questions. Speculations have been made about whether Dow Corning filed bankruptcy because of the financial hardship placed upon it by consumer lawsuits or whether Dow Corning used bankruptcy laws to shield itself from obligations to its consumers. This report will examine, 1) the ethical challenges and pressures each of these companies faced, 2) a review of Dow and Corning’s actions during the bankruptcy filing, and 3) a discussion of how Penn Square Banks ethical pressures might have been alleviated or offset. Penn Square Bank Penn Square Bank is an illustration of improper asset valuation. In an effort to grow Penn Square bank into a merchant bank and have it become a major financial backer to Oklahoma’s oil men, Bill Jennings hired Bill Patterson to lead his new energy lending division (Caskey, 1985). The energy lending division was tasked to find borrowers for oil customers. As loans were passed to other financial institutions; Penn Square collected fees for originating...
