Robots in the Medical Field


Whenever you think about hospitals, certain things come to mind, including doctors, nurses, operating rooms and patient beds. It is no wonder that you all think of mostly about the same things, since these are the things without which you can't imagine a hospital.

But what happens when you visit any hospital and you will find robots carrying first-aid trays going into private wards to give injections to the patients or walking in general wards for routine examination.

Although this is a not a new thing for us which we become to know but experiencing them everywhere has yet to happen and that's why maybe you will encounter this situation in the near future.

We must have read about robots or seen them cleaning floors, washing clothes and drapes rugs etc. in hospitals but now we can now see them doing other smart works including testing and diagnosing patients as well.

No doubt it is a kind of revolutionary event which has happened in our day-to-day life. In 1985, the Robot was first introduced in medical science its name is PUMA560. PUMA 560 was used in brain biopsy.

I remember when I was in ninth standard I had read about Brian Davies in a science magazine which comes in my school library. Mr. Davies is a scientist who has designed a robot which was capable of removing soft tissues from the human body; this invention has come into light in 1988.

It was a very inspirational invention in those days as technology was not so advanced.But because use of such kinds of machines is very bold step as human body is very sensitive from inside, so using the machinery inside the human body for which an extra care is needed by default as any rude or insensitive and nonsense treatment can cause fatal to the lives of patients.

So using insensitive machines in these places would have needed lots of support and confidence of 'will not happen anything wrong'.

The support of doctors which is needed most was not provided by them and hence use of robots has been limited to an extent.
The other thing was These places are very sensitive so use of robots with arms and legs could be very dangerous if someday they could not be controlled by the central system. Hence a decision of making very small robots was made.

And scientists have engrossed themselves in bringing their concepts alive. Scientists have decided to design robots of three axis and an additional axis after some time which can help in contributing Prostate surgery. But now the use of robots is becoming very common. Even I also know N number of people who have benefited from computer-assisted surgery.

Computer assisted surgery is also known as image-guided surgery is a 3-D surgery. It is a computer based procedure that uses technology of 3-D imaging and real-time sensing. It allows better treatment due to its ability of better visualization and targeting of sites.

Surgery by robots is not exactly the surgery done by robots, the whole procedure is controlled by human minds which are in other places of this world.Robotic surgery is nothing but a combination of computerized programming and mechanical parts including motors, sensors etc.

 

Minimal Invasive surgery

It is to be noted that these robots who will do medical tests etc. of patients are controlled by a central control system. Another thing which is becoming common nowadays in hospitals are Haptic devices.

Haptic refers to sense of touch. It is nothing but a form of non-verbal communication. Haptic devices are designed and works according to the concept of communication and as we know that different places has their own way to communicate, these haptic devices are designed differently. In some places voice recognizing technology is used in making the haptic devices whereas some can be designed with the help of sensing technology.
