VELAS30W 980nm diode laser for PLDD treatment

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.

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.
