Robots in medicine
Surgery
Possibly the most glamorous
application of robots in medicine, current state of the art couples a human
surgeon with mechanisms that can perform surgery through very small incisions, greatly
reducing the risk to patients. The surgeon's ability to control the mechanism
is enhanced by providing force feedback to the controls, allowing the operator
to have a sense of touch to help control the robot. This type of robot isn't
completely independent, and is more properly called a teleported device, but
uses much of the same technology an independent robot would employ for motion
control, imaging and tactile/force feedback. The fully autonomous surgical
robot that is a feature of science fiction literature and screen entertainment
is unlikely to appear in the near future, and even if technically possible, would
be viewed with great skepticism by patients (and their lawyers).
Diagnosis
Robotic test instruments
range from exotic scanners (such as computerized axial tomography: the CAT scan)
to laboratory equipment that processes and analyzes samples of blood and other
materials extracted from the body for diagnostic purposes. They provide
consistency and accuracy, reducing the possibility of human error that can
cause an inaccurate diagnosis. While not the classic industrial robot, they do
employ many of the same automation techniques.
Prosthetics
Mechanical replacements for
missing limbs and organs that can interact with the human organic system are a
long-standing goal of the medical community. Research into replacement hearts, limbs,
eyes, ears and other organs offers hope for the development of effective
implanted devices and replacement limbs that can function for long periods of
time. Robotic devices can also provide assistance to people with severe
restrictions on movement, in many cases allowing them at least some capability
to move around or nearby their homes.
One of the great challenges
facing the designers of implantable devices is the need to avoid stimulating
the normal immune system response to foreign objects, a response that can cause
serious complications or disable the device. It is also necessary for the
device to be able to survive in the biological environment without damaging
chemical interactions with the body.
Rehabilitation
Robots can provide exercise
platforms to help restore limb function and can monitor the condition of
patients undergoing rehabilitation from the effects of injuries, stroke or
other brain or nerve damage.
Pharmaceuticals
Industrial robots used to
manufacture drugs provide consistency and cost control in drug production and
can perform many process and handling steps without the risk of contamination
from human operators or exposing humans to dangerous chemicals or inadvertent
drug doses.
