ORTHOPAEDICS (PLDD)

LazSym-2

Compared with surgery, percutaneous laser decompression surgery is the least aggressive treatment (suitable for nucleus pulposus without prolapse of the outer layer). Pulsed laser vaporizes the protruding disc nucleus pulposus, reducing or eliminating nerve compression and stimulation. The 1470nm with larger water absorption properties appears to have an effect on the entire nucleus pulposus and not only in surrounding tissue of laser fiber (carbonization zone). During PLDD, disc volume is minimally decreased, however, disc pressure can be significantly lowered. When using laser for disc decompression, a small amount of nucleus pulposus evaporates.

The most important points of the machine

Combination of the medical laser and intelligent operation system

• Intelligent hardware control system. • Stable and continuous power delivery thanks to the liquid cooling system • The 1470nm and 980nm can be selected individually or blended together • 1470nm 25W max in CW mode for versatile treatment. • Combination of treatment data storage and patient data storage. • Nature-touched LCD allowing easy and rapid set-up.

Safety comes first

• The energy of the laser makes the diseased nucleus pulposus hollow, reduces the pressure in the intervertebral disc, relieves and eliminates the compression on the sciatic nerve or vertebral artery nerve, and will not cause damage to the peripheral nerve tissue • According to experimental studies, it has been determined that the temperature of the laser vaporized intervertebral disc will not have a scorching effect on the intervertebral foramen (nerve foramen) or spinal canal

Is PLDD demanding on physicians?

Of course, it must first be performed by a specialized surgeon, usually an orthopedic surgeon or a neuro interventionist. However, even for doctors who have not been exposed to laser surgery, the learning cost of PLDD is not very high. The whole procedure is relatively simple, the operation mode is fixed, and the laser will do most of the operations automatically.

What are the applicable wavelengths for PLDD?

For PLDD, the current mainstream wavelength choice is 980nm because 980nm has been clinically proven for a long time in terms of tissue absorption and widely accepted by physicians worldwide. However, more and more doctors are trying to apply 1470nm, because 1470nm has a better water absorption rate, and the water content in the nucleus pulposus of the disc is relatively high, and even trying the dual combination of 1470nm+980nm, which continues to be well accepted by the academic community.

What are the requirements of PLDD for lasers?

Since PLDD was invented in 1986, through continuous clinical improvement, the treatment environment of PLDD has gradually changed to 'in office' and 'outpatient basis', along with the demand for compactness, lightness and simple operation of the laser, which has gradually increased. In this case, 8kg Surgical Diode Laser System will be one of the best choices for PLDD laser.

When PLDD treatment is appropriate?

Not all herniated discs can be perfectly treated with PLDD, which is only suitable for cases where the nucleus pulposus is herniated but not completely detached or free. Therefore, a thorough examination by imaging is needed before treatment, and the doctor determines whether PLDD is suitable

What are the advantages of PLDD compared to traditional surgery?

The advantages of laser treatment are its controlled and precise fractional energy, which brings the advantages of small incisions, low complications and short recovery time. The same applies to PLDD, which can also achieve better postoperative results for herniated discs and no recurrence for a long time.

How to complete the PLDD surgery with laser?

• Use a spinal puncture needle to enter the diseased intervertebral disc (nucleus pulposus) through the skin, introduce a thin optical fiber through the puncture needle, and then activate the laser to vaporize part of the intervertebral disc nucleus pulposus. • The energy of the laser makes the diseased nucleus pulposus hollow, reduces the pressure in the intervertebral disc, relieves and eliminates the compression on the sciatic nerve or vertebral artery nerve, and will not cause damage to the peripheral nerve tissue. • After laser irradiation, the pressure in the intervertebral disc is reduced, and the nucleus pulposus will gradually be replaced by cartilage fibers. • According to experimental studies, it has been determined that the temperature of the laser vaporized intervertebral disc will not have a scorching effect on the intervertebral foramen (nerve foramen) or spinal canal.
