Overview of Surgery Over the years, surgery has made tremendous progress while changing human perspective; viewed as “no more science than butchery” a couple of centuries ago to now considered to be a solution for many health care problems threatening humans, like cancer, heart disease and kidney failure. Nevertheless, surgery has not been perfected to a level that provides successful results every time it is performed on patients. For example, surgery done to remove tumors in cancer patients result in only 45% of individuals to be cured. However, in order to be successful, the surgical procedure has to be carried out incredibly precisely and incomplete removal of tumors can decrease survival rate. Therefore, surgeons have to be able to recognize diseased tissue and distinguish it between healthy tissues. But even with the use of radioactive tracers and visuals, surgeons are not able to identify the exact site of the unhealthy tissue and its boundaries. Thus, almost 40% of the time cancerous cells are left behind because even the best qualified surgeons are not successful at the nanotechnological scale of tissue. One of the rational to this problem is the size of the surgical tools that are million times bigger compared to a single cell. In 1959, Richard Feynman, an engineer, proposed a solution for this problem by suggesting the idea of nanoscale surgical tools for more accurate diagnosis and assessment. Today, Feynman’s initiative is being achieved and many microscopic tools have already been developed for greater precision and faster healing; nanoscale tweezers, microscopic scalpels and nanoparticles. At the moment, the main objective for scientists and engineers is to develop surgery into a minimal invasive method and nanote... ... middle of paper ... ...e materials at the nanoscale might include new form of nanobase toxicity. The individuals working with large quantity of nanomaterials need to take appropriate measures to avoid inhalation and ingestion. However, scientists have found silicon o be good for the construction of nanorobots because of its unique properties; durability, flexibility and conductivity. However, silicon cannot dissolve in body fluids. In addition, in medical applications biodegradability is going to be challenge due to the foreign particles inside the body and controlled mobility. The small size ranging from 0.1 to 10 micrometres of nanobots make it difficult to be constructed. The process of working atom by atom and molecule by molecule is monotonous work and the miniaturization of synthetic mechanisms to a nanoscale will only be achievable with the advancement of research in metallurgy.

In the article “Pinpointing Cancer Fight,” Liz Szabo states the uses of nanotechnology and how researchers are attempting to use this advancement to fight cancer. She defines that nanotechnology is a type of technology that creates devices on an atomic level; this equipment can allow people such as researchers to use its ability to detect cancerous cells as well as treat them. Szabo remains a neutral tone as she states that while some are against the idea of using nanotechnology since there are many risks, others are optimistic that it may lead to transformational results. She presents a list of some products developed through nanotechnology and explains its usage in addition to mentioning the failure of those nanotech products. Szabo provides
... The advanced technology of surface modification in the biomedical sector have the ability to offer not an improvement in the tribological properties only but also to improve the clinical requirements prior and post implantation. Such properties includes cell growth and antibacterial effect.
It is clear that nanotechnology has the potential to revolutionize health care and even transport
Robotic Surgery is an emerging technology that utilizes purpose-built robots to perform surgical procedures on patients. At present these robots are not autonomous, they are controlled by a surgeon at all times.
Plastic surgery is a diverse specialty, encompassing hand and craniofacial surgery, tissue reconstruction due to various deficits caused of excisions, cancer, trauma or congenital defects, aesthetic surgery and burn care. So, as far as plastic and reconstructive surgery are concerned, nanomedical market offers a broad variety of medical and technological achievements to be used in wound healing, cosmetic appliances, burn and skin care, regenerative medicine, drug delivery, implants and tissue engineering.

Nanotechnology is the manipulation of structures at nano levels. It uses incredibly small materials, devices, and systems to manipulate matter. These structures are measured in nanometers, or one billionth of a meter, and can be used by themselves or as part of larg...
Biomechanical engineering is driven by needs similar to those of biomedical engineering. There is always a constant need to improve medical equipment while keeping it cost efficient. These are the two main needs for all biomedical engineers. Biomechanical engineering is specifically dedicated to applying the scientific of knowledge mechanical systems and engineering to biology and the human body. One of the many needs that drives this biomedical subfield is society’s need for more advanced equipment and machinery. Some recent advances show this need. In the last decade, biomechanical engineers have invented and innovated new robots and machines that can assist a surgeon in surgery or serve as an artificial liver. These machines satisfy the need to improve and innovate new equipment that can save lives and improve how people in the medical field perform their
Since the beginning of time, human beings have been in search of ways to advance life as we know it. Every single day, somewhere in the world, technology is being transformed and an exciting new piece is birthed into society. Perhaps, one of the most influential advances is in our ever evolving medical profession. Thus, as technology continues to change the world as we know it, it is sweeping the medical field right along with it. Surgical procedures are being drastically improved with the use of robotic technology called da Vinci.

Figure 1: Image of the nanoscale, this illustration shows how small things at the nanoscale really are (nano.gov, 2013).
Nanotechnology includes nanorobots which are so small that they can be injected into the human bloodstream after which the nanorobots can do investigations or repair at cellular level. Nanorobots could optimize the delivery of pharmaceutical products, these means that medicines which are targeted on a specific type of cells can be delivered to only those cells by the nanorobots. The robots can attach to the cells after which they can inject the drug into the target cells. This could be a great breakthrough for cancer treatments such as chemotherapy because there is a minimal chance of injecting healthy cells with the drug and therefor negative side effects can be avoided.
One of the reasons that the microscope is a great invention is the help that it has provided in the field of medicine. The microscope has helped to diagnose and find treatments for many diseases. An example of this is seen when looking at how cancer is diagnosed. Physicians can take biopsies of a tumor or growth, and examine them under a microscope. At the microscopic level, they can look at the patient’s cells to see if they are cancerou...
