980nm lamber laser for Minimally-Invasive PLDD Laser Surgery
The PLDD is a minimally invasive technique for the treatment of
disc herniations. It uses only a thin needle in which an optical
fiber is inserted and it uses local anesthesia. The needle is
introduced posteriorly in the lumbar cases and at the anterior
right lateral level of the neck for cervicl cases, at an exact
entry point. The needle is pushed forward carefully, under
radiological control, to reach the center of the disk from which
the disc herniation originates.
At this point, laser pulses are delivered and these must to be
individualized from patient to patient with precise parameters
(single pulse power, pause time in seconds between one pulse and
the next one, total laser energy delivered). The laser pulses
vaporize a very small amount of the center of the disk (called
nucleus pulposus that is rich in water) and this produces a marked
reduction of the pressure inside the disc and consequently also a
reduction of the pressure that the hernia exerts on the nerve root
(cause of the patient's pain). It should be noted that the goal of
PLDD is not the disappearance of the herniated disc, but to reduce
the pressure it exerts on the nerve. An example that makes good
sense is if we consider hernia as a very puffy balloon that presses
on the nerve. The PLDD aims to deflate the balloon and thus to
eliminate the pressure exerted on the nerve (for this reason it is
called "decompression"). There are no cuts of the skin, muscles,
ligaments and bone removing as in the "classical" or endoscopic
surgical technique.

PLDD laser system is specially designed for PLDD mini-invasive
surgery, providing a full set of high quality standard and optional
accessories, such as puncture needle, Y-valve, optical fiber,
safety goggles, footswitch, fiber cutter, carry case, cart and etc.
The sterile kit include a 400 micron bare fiber with jacket
protection, 2 sizes of needles, 20G and 18G for your choice of
entry, and a Y Connector allowing fiber entry and suction. The
connector and needles are individually packed to enable maximum
flexibility in treatment.
Berylas 980nm PLDD laser systems are specially designed for the
PLDD procedures. The 980nm wavelength offers equal absorption by
blood and water, enabling efficient and precise tissue ablation and
coagulation as multi-purpose surgical tool.The PLDD treatment is performed on an outpatient basis using only
local anesthesia. During the procedure, a thin needle is inserted
into the herniated disc under x-ray guidance. An optical fiber is
inserted through the needle and laser energy is sent through the
fiber, vaporizing a tiny portion of the disc nucleus. This creates
a partial vacuum which draws the herniation away from the nerve
root, thereby relieving the pain. The effect usually is immediate.
Cervical Problems
One or more cervical disc herniations
Neck pain, shoulder pain, bilateral numbness, dizziness and other
symptoms.
Lumbar Problems Restrictive disc herniation on CT or MRI
No intervertebral disc calcification, free, prolapse
Straight leg elevation test positive
Six weeks of conservative treatment is inva
