NEUROSURGERY SMART M NS
Percutaneous laser disc decompression (PLDD) is a minimally invasive procedure that aims to significantly reduce the patient’s pain and neurological deficit.
- Simple and intuitive operation
- Greater precision of procedures with reduced tissue invasiveness
- Quick return to daily activities
- Pain reduction
- No need for hospitalization
- Lowest operating costs
A Brief History of Laser Therapy
In 1986, Peter Ascher and Daniel Choy at the Department of Neurosurgery, University of Graz, Austria, performed the first percutaneous laser decompression procedure of the intervertebral disc in the lumbar spine.
Since 1987, percutaneous laser disc decompression (PLDD) has been used in the clinical treatment of disc prolapse. Since then, the PLDD technique has spread worldwide, and procedures are performed on the entire spine except for T1–T4 (these discs do not allow percutaneous access with a needle). The method is widely used in the United States.
The first experimental procedures were performed on animal intervertebral discs using a neodymium-YAG laser – Nd:YAG. The first clinical procedure in history was performed with this laser model. Work on the use of different types of lasers led to the introduction of the diode laser into clinical practice.
In Poland, procedures using a diode laser have been performed since 2003 at the Neurosurgery Clinic of the Central Clinical Hospital of the Ministry of Interior and Administration in Warsaw.
Why is there not one wavelength?
A novelty among medical devices manufactured by Lasotronix is the two-wave, universal surgical laser SMART M 980/1470nm, which, in addition to phlebology and proctology, is widely used in dermatosurgery, laryngology and gynecology.
Additionally, SMART diode lasers can be extended with an additional wavelength – 635nm, which, thanks to biomodulation effects, has a very beneficial effect on morphological elements of human blood. Treatments with this wave significantly improve the process of soft tissue regeneration, rebuild blood vessels, reduce postoperative pain and swelling, stimulate blood and lymph flow and strengthen local immunity. The use of the 635nm laser is especially recommended for patients undergoing inflammation, difficult-to-heal wounds or ulcers, and after each procedure to accelerate healing, reduce pain and swelling.
For minimally invasive intravenous laser ablation – EVLT, Lasotronix offers diode lasers emitting radiation at various wavelengths: 980nm, 1470nm or 1940nm with the possibility of further expansion with additional light sources.
As can be seen in the graph, for 980nm radiation, the absorption coefficient is higher for hemoglobin than for water. In the case of 1470nm, especially 1940nm, it is the opposite, and water absorbs light radiation many times better than hemoglobin. Both of these chromatophores are components of human tissues, including blood and vessel walls. Lasers with a wavelength of 980nm have been used on a large scale for over 20 years, and the average power used during procedures is 10-12W. At a wavelength of 1470nm, lower powers are needed – at 6-8W, and for 1940nm waves, 4-6W is enough to perform an effective operation. Reducing the amount of power needed makes these lasers much safer and predictable tools for the doctor, while providing patients with a faster and more comfortable recovery.
