What is Holmium Laser and Advantages on Medical Treatment?

 With the continuous use of holmium laser in medical treatment, holmium laser therapy machines are increasingly selected and used by more hospitals and medical institutions, which greatly improves the medical level. So what is the holmium laser? What are the specific medical advantages of the holmium laser (Ho:YAG) treatment machine? As an invester on the holmium laser(Ho:YAG) treatment machine manufacturing and researching, we will give a general introduction about it in below:

Holmium laser is a new type of laser produced by pulsed solid laser device made of yttrium aluminum garnet (YAG) as the active medium, doped with sensitized ion chromium (Cr), energy transfer ion thulium (Tm) and activated ion holmium (Ho) laser crystal (Cr:Tm:Ho:YAG)

It can be used in urology, ent, dermatology, gynecology and other departments. The laser procedure is non-invasive or minimally invasive, and the patient's treatment pain is very small.

 

The application of holmium laser has brought the treatment of urinary calculi to a new level. The holmium laser, with a wavelength of 2.1μm and a pulse laser, is one of the latest lasers used in many surgical procedures. The energy produced can vaporize the water between the end of the fiber and the stone, forming a tiny void, and transfer the energy to the stone, so that the stone is crushed into a powder. Water absorbs a lot of energy and reduces damage to surrounding tissues. At the same time, the penetration depth of holmium laser to human tissue is very shallow, only 0.38mm. Therefore, the damage to the surrounding tissue can be minimized and the safety is extremely high.

 

The laser used in the past has many disadvantages, such as non-pulsed carbon dioxide laser, it is the use of thermal effect vaporization of stones. Due to high temperature (2000 ~ 3000℃), so the heat damage is large; Pulsed lasers, such as dye lasers, they are ineffective for cystine stones without pigment; Neodymium lasers cannot be used for lithotripsy because of their poor accuracy.

 

Holmium laser has the advantages of precise control on energy transmission and subsequent incision, what's more, small penetration, shallow cutting depth, relatively narrow thermal damage area, limited damage to surrounding normal tissue, and high safety. Moreover, the operation is under direct vision, and the small-caliber optical fiber with various caliber endoscope can easily reach any part of the urinary system, which is an ideal tool for internal incision. It can be used for: (1) internal incision of urethra and bladder neck stenosis; (2) Internal incision of ureteral stenosis; (3) Internal incision of ureteropelvic junction stenosis (UPJ); (4) Internal incision treatment of congenital megaloureter; (5) Internal incision of ureteral intestinal stricture after urine flow diversion; (6) Laser incision of ureterocele in children; (7) The infundibular part of the calyceum is operated with stenosis. In addition, holmium laser can also be used for decompression of uroepithelial cysts, suturing of hypospadias and so on. In short, the holmium laser is a solid-state laser with an emission wavelength of 2100nm, which combines the characteristics of a CO2 laser and a neodymium laser, using the same device to both cut tissue and solidify bleeding. The holmium laser wavelength can be transmitted through optical fiber, so it can be used in endoscopic surgery. With the continuous improvement of endovascular urology technology and holmium laser technology itself, it is believed that holmium laser will be more and more widely used in urology.
