Nanorobots are tiny machines that can be injected into the body to cure diseases. They are smaller than blood vessels and can navigate through the body using blood flow and ultrasonic positioning techniques. The nanorobots use sensors to detect issues like blockages, and then destroy fatty deposits or clots using special blades. Any damaged areas are then synthesized with new cells by the nanorobots. While this heart surgery technique using nanorobots would be less invasive and more accurate, the technology is still expensive to implement practically.

3. Nanorobots are tiny
machines used to cure
diseases in human or in any
organism.
The size of nanorobots is 10
to the power -9.
These nano scale devices are
high in performance.

5. INJECTION OF
NANOROBOTS
Nanorobots are introduced into
the body by surgery.
So the nanorobots are made
smaller than the blood vessels as
it can travel.
The nanorobot is injected in
femoral artery

6. NAVIGATION &
POSITIONING
Nanorobots use blood flow for
its movement.
To know the location of
nanorobots where it goes we use
ultrasonic technique
Signal processing techniques are
used to track this ultrasonic
signal

7. SENSORS IN DETECTION
ACOUSTIC SENSORS in sensor
robots get activated soon.
It navigate itself by the arm of
robots through the blood stream to
the pericardium.

8. SENSORS IN
DETECTION(CONT)
The PRESSURE SENSORS scan blood vessels for
variation in blood pressure
They will generate a report of the potential areas of
heart block.

9. SENSORS IN
DETECTION(CONT)
The SMART SENSORS present in the sensor robots, get
activated.
They form a closed ad-hoc network connecting all the
robots.

10. SENSORS IN
DETECTION(CONT)
CHEMO SENSORS scan the region
of the cholesterols,
It is used to find the block
accurately.
All these information are
transmitted through the ad-hoc
network.

11. DESTRUCTION
The fatty deposits (or) clots are
removed using special blades
fitted with nanorobots.
Continuous (or) pulse signal is
used to activate the blades.

12. MOLECULAR SYNTHESIS
The final operation Is done by the
molecular synthesizers.
They fill the burnt gap with fresh
cells synthesized by the robots
themselves.
This process is known as
Molecular synthesis.

13. advantages
Fast process & results are accurate.
Involves less psychological strain
Harmful ray attack is reduced.
Side effects are eliminated

14. disadvantages
Expensive technology
Practical implementation is some what difficult.
Some times robots goes out of control in human body

15. conclusion
Nanorobots performance in heart surgery is found to
be effective.
As the construction of nano robots is under progress,
the ideas explained here could not be implemented at
present.
This will be implemented soon in future
