Clinical Application:
VELAS30W 980nm diode laser for PLDD treatment from GIGAALASER
Clinic Explanation:
PLDD (Percutaneous Laser Disc Decompression) be acknowledged as the most effective
Minimally invasive surgery for spine. The laser energy is introduced by a fiber inserted to
The nucleus pulpous under the monitoring. Then the herniated intervertebral discs are
Treated by reduction of intradiscal pressure though laser energy.
Thanks to VELAS30B with 980wavlength which have a good absorption of water, enable
The PLDD procedures to be carried out safety, accurately, less bleeding and pain.
Related Keywords:
PLDD (Percutaneous Laser Disc Decompression), lumbar disc herniation, minimally
Invasive surgery, less bleeding and pain
Medical device:
VELAS30W, 980nm
Mode: Pulse,
T-on: 1s, T-off: 3-5s
Operation power: 15-18w
Accessories:
600um fiber, PLDD set,
Operation procedure:
1. Make the patient place in prone position on CT table.
2. Decide the puncture point and pathway by CT scanning.
3. Local anesthesia.
4. Insert the 18G puncture needle in the midline with 8cm deep, pointing toward the
Centre of the disc. Verify the needle in correct position by CT imaging.
5. Removal the stylet of the needle and then insert the 600um bare fiber. Make the tip of
Fiber expose about 3-5mm and then connect Y-valve.
6. Open the device, letting the laser energy vaporize the herniated intervertebral discs
And then reduction of intradiscal pressure. During the operation, using the Y-valve for
Lymphosuction when patient feel swelling.
Advantage:
1. Minimally invasive operation, with no bleeding and no scar.
2. Easy to operation, the surgery can be done on local anesthesia and more quickly.
PLDD TREATMENT MANUAL
3. Can treat several intervertebral discs disorder at same time.
4. The surgery do not involve in operation in the inner of canales spinalis, so it less or no
Complication after the surgery.
5. Less pain and discomfortable, enable the patient quickly back to daily life
Notice:
1. Patients should be excluded if they had previous surgery at the indicated level, disc
Extrusion, and spinal stenosis.
2. In order to open up the posterior aspect of the disk space, soft pillow is positioned
Under the abdomen of each patient to place the lumbar spine in a semi-flexed
Position.
3. The total energy applied in each disc will decided by patients' spine condition. The
Suggest energy is about 1200-2000J.
4. The patients are suggested to take bed rest for 1-3 days.
5. Patients should are given mannitol and antibiotic therapy for 3 days.
6. Patients were instructed to avoid heavy lifting, heavy exercises and long time sitting or
Standing for 3 months.
