3D Bone Printing The realm of biomedical research is constantly changing with advances in technology. One of the new technologies on the biomedical research horizon is three dimensional (3D) bone printing. Top surgeons and doctors worldwide are honing this 3D bone printing technology to create bone replacements (Lewis, 2013). 3D bone printing technology is being used several ways to aid in medical treatment. In some instances, researchers are using 3D printing coupled with 3D imaging to replace bones and cartilage in the body with synthetic materials that are stronger than bone (Ducharme, 2013). Other researchers are combining 3D printing with stem cells to regenerate new bone tissue (Lewis, 2013). The various utilization of this 3D bone printing technology portrays the impact that it will have on advancing medical treatment options. One of the current 3D printers is able to print at high speeds using a specific type of nylon, which has been found to be well tolerated by the human body and stronger and more durable than bone (Staff, 2013). The surgeon can take this new 3D printed bone, that is specific to the patient, and replace it within a few hours (Staff, 2013). This technology is coupled with the use of 3D imaging, and is lower cost and time …show more content…
In this process first the 3D printer creates a “scaffold” in the exact shape of the patients bone (Lewis, 2013). The scaffold can be made out of hydroxyapatite or porous ceramic material, as they both have shown biocompatibility for tissue generation (Irsen, et al, 2005). Next, the scaffold is coated with stem cells that will develop into fully functional bone tissue (Lewis, 2013). The stem cell covered scaffold is then placed into the body and after about three months the scaffold degenerates and is replaced by new bone tissue (Lewis, 2013). Like the previous process, this process also is both time and cost effective (Lewis,
Death: a reality that rarely crosses people 's mind, with a major exception being when one crosses the threshold of an operating room. The operating room holds a special terror for both patients and their family members. For the patients, they must face the possibility that they could fall into an eternal slumber, and for the family members, they must recognize the fact that their beloved has a chance of not surviving. It is even more agonizing when a new procedure like the anterior approach hip replacement fails to uphold its reputation: one as a new, innovated technique meant to improve the quality of life, not destroy it. The mortality rate for the anterior approach hip replacement is far too devastating considering the fact that the posterior
Similarly, it was important for the content of this paper, to interview a physician on how it would impact their specialty. The internet had valuable insight from anesthesiologists, general surgeons and emergency responders on how the Glass product may be useful in their lives. Fortunately, an orthopedic surgeon made himself available for an interview, and his insight was into his specialty was much appreciated. Dr. James L. Rushford, D.O., had previously head about the Google Glass product before, and heard about some of the advantages the product would bring to other specialties. Unfortunately, there has not been much in the way of its application discussed in orthopedics.
Recently, I have been following the “head transplant surgery” proposed by a neurosurgeon, Dr. Canavero. He plans to severe the head of a quadriplegic and transplant it onto the body of a brain-dead person. If the operation is successful, the patient will gain full motility in a year. When I first learned about Dr. Canavero’s plan, I quickly dismissed it as an impossible feat since the spinal cord was never successfully reconnected in a test animal, let alone in a human. However, Dr. Canavero recently took me by surprise by managing to severe and reattach a mouse’s spine; in merely a month, the mouse gained partial motor functioning.
New Technology: Helping or Hurting Doctors and Surgeons? Have you ever wanted to cut someone open and literally hold their heart in your hands? What about look at the human skeleton up close and personal? For doctors and surgeons, this is just a normal day on the job.
One of such advances is artificial intelligence which has been greatly improved in healthcare. In the future, there are impressions that artificial intelligence will surpass human ability in healthcare, such as to raise concern in some quarters Nilsson & Sollenborn (2004). Robots operating with artificial intelligence, have played significant role in healthcare and they are expected to also improve in there usability Nilsson & Sollenborn (2004). Another area of potential advancement in healthcare sciences, is the application of 3 Dimensional (3-D) printing technology for the repair or replacement of organs in the human body. As the technology improves, it is hoped that, human wellbeing and in some cases, life can be improved with the use of 3-D printed body parts, thus, whereas the concept is undergoing testing and review, the future of 3-D technology in healthcare sciences appears bright.
My thoughts are that this is a very inventive procedure because people without certain body parts could possible grow one with the works of science. Charles Vacanti commenced the project in 1989, where he successfully grew a piece of human cartilage onto an environmental scaffold. He used scaffolds similar to actual surgical stitches. While in the body this is converted
Overall biomedical engineering in general is a thriving technology that will advance the world more than it ever has. As it continues to grow more things have been developed to help human’s live easier and more stable lives. In the future we can look forward to better prosthetic limbs in the area of natural feeling and physical appearance that can help in health and
Computer reckons perspective to simulate the reality and modify the captured image into the image that will be projected on the clock. This technique is image based rendering. PROJECTOR AND COMBINER: PROJECTOR: The transformed image must be shone on to the cloak. The image is sent through an opening controlled by iris diaphragm .Its
The field of tissue engineering still debates whether or not the use of natural scaffolds (ECM) or synthetic scaffolds are ideal when it comes to the longevity, mechanical strength, and efficiency of engineered tissue following transplantation. Although both natural and synthetic scaffolds can be used in tissue engineering, the benefits of creating natural scaffolds through decellularization of the ECM greatly outweighs those of synthetic scaffolds. Fishman and colleagues (2014) highlight these benefits by comparing natural scaffolds to synthetic scaffolds. Biological scaffolds that are composed of ECM are a better representation of native tissue and can accommodate growth more efficiently than artificial materials in synthetic scaffolds. As previously
Fix or replace damaged tissue; biology has always been the main concern for scientists. Today, the most important instrument for tissue engineering scientists to produce replacement tissues and implants to repair or replace damaged tissue. Tissue engineering is generating a new field of study in which the principles of engineering and biology to correct the damaged tissue, uses and can renewal, operation and maintenance of tissue healing. In order to use an ideal scaffold Tissue engineering should have features such as non-toxic Cell and tissue properties to be fit.
But wait there 's one more, the Cosmetic prostheses do not improve function, but are used to improve a person 's appearance after the loss of a body part. These include ocular prostheses -- artificial eyes -- and silicone hands, fingers, feet and toes. People with prosthetic legs can often climb stairs, walk, swim, and run as if h they were using natural limbs, while prosthetic arms and hands have advanced to the point where they give the individual control of all five fingers. If this is what scientists and doctors have accomplished in the past 50 years, it is difficult to imagine how much technology will improve within the
Whether it’s a mundane or practical application like instructions in a piece of equipment or medical information of a patient or something more a little complex like taking situational awareness information presenting it to a soldier or to a police men, augmented reality seems to have such a great advance impact in technology and has become an important aspect of
