Herniation of intervertebral disk takes a high disease incidence in human's life. The traditional surgery for intervertebral disk causes the big trauma and long convalescent phase. While PLDD will become the most convenient and effective way of the minimally invasive laser operation for herniation of intervertebral, with it's advantages including fine puncture needle, small wound, easy controlled laser energy, easy operation, safety, and rapid recover.

The clinic trials prove that SurgiLas has the excellent ability of incision, vaporization and coagulation. With the moderate transmitted depth, it hardly makes injury for the tissues around, causes a cavity of intervertebral, effectively clear off the pressure to tissues, and haven't any damage to the front and the posterior intervertebral disk, interior wall of intervertebral foramen and gristle.

Therapy elements of PLDD

When percutaneous puncturing, the laser is been transmitted through fiber to the front and middle part of intervertebral disk, causing the vaporization of pulpiform nucleus, lowing the intervertebral disk's pressure, which can lessen and relief the stimulation and oppression to dura mater sac and nerve root and have an ideal curative effect.

The features for PLDD

* The wound can be only 1mm if using SurgiLas for percu under X-ray.

* Local anesthesia, non-bleeding, obvious pressure effect, non-

   postoperative complication and remarkable curative effect.

* Operation under fluoroscopy, easy use and safety, short operation time.

Equipments of PLDD

* SurgiLas

* 'C' arm-type X-ray for orthopedics department

* Professional medical fiber with 400¦Ìm, type 18th of puncture pin, 'Y' tube
