| Q. |
What are the advantages of the laser surgeries? |
| A. |
Lasers have not replaced scalpels. But they
do help doctors perform some procedures more effectively than
with traditional methods. Lasers cause minimal bleeding, allowing
surgeons to have a clear view of the area of surgery. Because
of their precision, lasers allow doctors to work on small and
hard to reach parts of the body.
In some cases, laser surgery is faster than traditional surgery,
quickening recovery time. Some laser surgeries are performed
under local anesthetic in a doctor's office. Others require
general anesthesia and a hospital stay. |
| Q. |
What is the significance of wavelength 970nm? |
| A. |
The 970nm wavelength matches well with the local
maxima of water and oxiheamoglobin absorption, the main components
of the human soft tissue. Due to this, the laser light at this
wavelength gets absorbed in the surface layers of the soft biological-tissues
and the risk of damage of deeper laying organs by laser radiation
is reduced. The 970nm radiation, as compared to electro-coagulators,
has better coagulation effect. Post-operating pain effects are
lower. |
| Q. |
What is the specialty of the aiming beam provided
by SST diode lasers? |
| A. |
The devices use green laser pointer, which can
be easily identified on the background of the red blood-carrying
tissue and does not get absorbed by 970nm protective laser goggles.
The output power of the surgical laser and brightness of the
pointer can be adjusted using controls on the front panel of
the device. |
| Q. |
What is the mode of delivery of laser light? |
| A. |
The delivery of the laser light is through an
optical fiber with the light-transmitting core made with water
free quartz. This is required to reduce absorption of transmitted
light. Exchangeable fiber cables are capable of undergoing multiple
cold sterilization. |
| Q. |
Is it possible to use through endoscopes? |
| A. |
The fiber output of the laser can be brought
to the operational zone via instrumental channel of an endoscope,
hollow needle or special hollow-channel hand-pieces. |
| A. |
Yes, the machine is very compact and robust
machine and weighs just about 7 to 9kgs. It doesn’t require
any specialized cooling mechanism. |
