Image
guided surgery makes use of preoperative images to precisely guide
surgical instruments by correlating the operative field. The image
guidance systems also help in seamless procedure planning, thus
reducing chances of error and also minimizing procedure time. With
image guided systems, overall productivity is increased and being
minimally invasive, allows quick recovery and shorter hospital stay.
The technique was initially developed for neurosurgeries, which is
one of the most critical procedures. ENT surgeries still remain the
main area of application of image guided surgery systems. Major
indications where image guided surgery can be performed are sinus
surgery, and treatment of diseases which critical areas of cerebrum
where chances of error must be minimum. Oncology is a major area of
application of image guided surgery, where various methods are tried
and tested for efficient treatment. With the development of
technology and optimization of procedures, image guided surgery is
expected to be the main stay for neurological surgeries, especially
in treatment of brain tumor.
Ultrasound,
magnetic resonance imaging (MRI) and computed topography (CT) are
majorly applied in image guidance systems. Fluorescence image guided
surgery is also becoming popular, as it cost effective as compared to
other devices, but poor depth penetration is a restraint. Fluorescent
dyes are used to stain the abnormal tissues and light with different
filters is used for visualization. Indocyanine green and methylene
blue are commonly used dyes for fluorescence image guided surgery.
This technology has been further refined by combining it with
endoscopy devices. Robot assisted surgeries have also helped in
minimizing errors during surgery and have also helped surgeons to
carry out critical surgeries effectively.
These
robot assisted systems are also combined with image guided surgery
systems. Brainlab manufactured Curve Image Guided Surgery Systems and
MAKO manufactured MAKOplasty systems are few examples of latest
technology robot assisted image guided surgery systems. Advent of
high definition (HD) and three dimensional (3D) visualization systems
have further revolutionized the image guided surgery systems by
improving image quality and improving depth perception. Ergonomic and
miniaturized devices have made procedures convenient to surgeons.
These factors will increase the adoption of image guided surgery
systems and hence assist market growth.
Statistics
published by National Cancer Institute, U.S. indicate that there were
more than 150,000 individuals diagnosed with some type of cancer of
nervous system including brain cancer in the U.S. alone. The
statistics also estimated approximately 14,000 new cases may arise by
2014 in the U.S. According to a healthcare website, MedIndia, primary
brain tumor accounts for 20% of the cancers in pediatrics in India.
Such high prevalence and ever increasing burden will increase the
customer base for image guided surgery market globally.
Higher
cost however is restraining the market growth in developing countries
where hospitals do not have enough funds to upgrade their hospitals
to expensive latest technology. Moreover lack of skilled surgeons for
image guided surgery is also a major factor affecting its adoption.
Furthermore patients in developing and under developed countries do
not have the basic ability to pay for expensive treatments and hence
opt for cost effective surgeries options. Hence the market for image
guided surgeries is currently abominated by North American and
European countries. Favorable reimbursement policies, surgeon
training and development events, well equipped hospitals are driving
the market. Some of the key players in this market include MAKO
Surgical Corp. (acquired by Stryker), Medtronic, Brainlab AG, Scopis
Medical, Claron Technology, Inc., and GE Healthcare.
