Mechanical Arms to Help in Surgery

Most of the time man need a helping hand and no matter it’s of a robot!!

A mechanical arm as it is defined is a robotic, usually programmable, with similar functions to a human arm. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement.

Surgeons in the US have pioneered the use of a mechanical arm laden with sensors to track the positions of their surgical instruments while they operate on patients' brains. The sensor arm allows them to watch their manoeuvres live in three dimensions on a video monitor. This system and other robotic devices developed or under development by companies such as Computer Motion (Santa Barbara, CA) and Integrated Surgical Systems (Davis, CA) have the potential to revolutionize surgery and the operating room. They provide surgeons with the precision and dexterity necessary to perform complex, minimally invasive surgical (MIS) procedures.

James Zinreich and colleagues at Johns Hopkins Medical Institution in Baltimore have used the sensor arm successfully in five operations to remove deepseated brain tumours, and they are now adapting the system for sinus surgery.
In the US, 38 million people suffer chronic inflammation of the nasal cavity and paranasal sinuses. Although sinus surgery using a fibre-optic endoscope inserted through the nostril to see inside the sinus has become commonplace, the small size of the endoscope restricts the surgeon's field of view to between 1 and 2 centimetres.

 

Manufacturers believe that their products will broaden the scope and increase the effectiveness of MIS; improve patient outcomes; and create a safer, more efficient, and more cost-effective operating room. It is the vision of these companies that robotic systems will one day be applicable to all surgical specialties, although it is too early to tell the full extent to which they'll be used.

Surgical robotics manufacturers working toward FDA approval of their devices are encouraged by Intuitive Surgical's recent FDA approval. "The future looks bright," says Yulun Wang, MD, founder and chief technical officer of Computer Motion. "This approval sends a positive signal to industry, and there are tremendous opportunities."

Scope of Mechanical Engineering

Scope Of Mechanical Engineering

Mechanical engineering is one of the oldest branches of engineering. It is also referred to as the ‘mother’ branch of engineering. Another appealing feature of mechanical engineering is that the application base of this field of study is extremely broad and diverse. Almost all inventions during the ancient period and a vast majority in the modern era are direct contributions of one or the other application of mechanics.

Traditionally, mechanical engineers have to deal with concepts such as mechanics, thermodynamics, robotics, kinematics, structural analysis, fluid mechanics and many others. These concepts are applied in the process of designing state-of-the-art manufacturing units, different types of motor vehicles, aircraft and aerospace parts and a vast assortment of industrial machinery. Mechanical engineers also contribute in the development of various engines, power plant equipment, heating and cooling systems and other simple and complex machinery. Mechanical engineers not only design new mechanical systems but they are also responsible for testing, maintaining and manufacturing them.

 Career Paths

Generally recognized as the engineering discipline that offers the broadest choice of technical career paths, Mechanical Engineering can lead you in paths other majors cannot. Mechanical engineers work in all facets of industry developing technologies for nearly every product we use.There is a wide scope for mechanical engineering worldwide.mechanical engineers are the second highest employed engineers among all others with only 7% unemployed whereas any normal engineering stream would have around 15% unemployed engineers worldwide. We have the automobile industry,oil and gas production companies,aeronautical field,cement industries,design sector,chemical industries,heavy machinery sector,information technology,defense and above all the booming construction field always waiting on for mechanical engineers with lucrative pays and packages.

SALARY

The average salary for mechanical engineers in the USA is $69,850, of which the top 10 percent earn a salary of around $104,900, and the bottom 10 percent earn an average salary of around $45,170. Mechanical engineers with a bachelors degree can expect to earn a starting salary of approximately $54,128, whilst those with a masters degree have an average starting salary of approximately $62,978, and those with a doctorate degree have a starting salary of $72,763 on average.

WeLcOme to M 4 MEchnical Engineer blog. Most of Us don't know even the definition of Mechanical Engineering; so lets start from the very definition of Mechanical Engineering!

According to The American Heritage Dictionary:

                                      

         "Mechanical Engineering is a discipline of engineering 

              that applies the principles of physics and material science 

          for analysis, design, manufacturing, and maintenance of

          mechanical systems. It is the branch of engineering that

              involves the production and usage of heat and mechanical

                  power for the design, production, and operation of machines 

and tools."

This blog is a relief for most of mechanical engineering students to help them out for their assignments and projects.  Interesting information will be shared on this block not only for mechanical engineers but for the people related to science and technology; that will be intriguing

 and would surely give you a chance to turn your brain in to a machine that would generate most interesting and creative ideas.
