Lasers for Medical Treatment

 

Laser used in medical field is the most important high-tech medical technology in this century, laser medical treatment relates to all clinical disciplines, such as ophthalmology, dermatology, surgery, dentistry, oncology, cancer, etc. Laser has a revolutionary breakthrough in medical treatment, and different wavelengths suit for different therapeutic areas.

 

Changchun New Industries (CNI) founded in 1996, is a leading manufacturer of solid-state and diode laser systems. CNI laser features with high performance, high reliability, and specifically designed for OEM, scientific, medical, industrial and instrumentation use. In addition, CNI lasers are ISO-9001, FDA, CE, RoHS and JQA certified. CNI can provide different lasers for medical treatment with free space and pigtailed versions. Also the accessories related are available for a total solution from customers.

 
 Laser Therapy
 

Laser therapy

Areas of application:  
External laser therapy Interstitial laser therapy
Intra-articular laser therapy Intravenous laser therapy
Pain therapy Photodynamic therapy
Common wavelengths:  
447nm, 532 nm, 589 nm, 655 nm, 810 nm...

 

With free space or fiber coupling output option, usually the power is 5~100 mW for 447 nm blue laser, 5~50 mW for 532 nm green laser and 589 nm yellow laser, both power and frequency can be adjusted individually.

 
 Laser for Ophthalmology
   

Laser for Ophthalmology

Eyes are the most sophisticated, one of the most important organs. Also eyes are very fragile and vulnerable. Once the eyeball appears lesion, it is difficult to remove the lesion safely by normal surgery. While most organizations of eyes are transparent, which allows the beam to get through. With the development of laser science, people realize to use the laser for eyes treatment, and achieved good results.
Areas of application:  
Retinal photocoagulation   Trabecular angioplasty
Iridotomy Lamellar keratoplasty
Cataract surgery Vitreous Lysis
Common wavelengths:  
532 nm, 561 nm, 577 nm, 635 nm, 671 nm, 810 nm, 980 nm, 1064 nm, 1320 nm...

 

Normally several millijoules are needed for pulsed laser, such as 2 mJ for 532 nm laser and 10mJ for 1064 nm laser. The power is around several watts such as 2 W, 3 W for 532 nm green laser.

 
 Laser for Dermatology
   

Laser for dermatology treatment has also made rapid progress over the past decade. In Europe, America, Japan and other countries, dermatologic surgery uses non-intervention type of treatment to achieve a good therapeutic purposes, instead of  traditional surgery, transurethral resection, skin grafting and other technologies. Currently, the laser has been widely used in in varieties of skin and beauty items.
Areas of application:  
Vascular lesions Pigmented lesions
Onychomycosis Tattoo removal
Hair removal Laser resurfacing
Common wavelengths:  
532 nm, 593 nm, 650 nm, 750 nm, 808 nm, 980 nm, 1064 nm, 1085 nm, 1320 nm, 1342 nm, 1550 nm...
Normally single pulse energy for pulsed laser needs hundreds to thousands millijoules such as 400 mJ for 532 nm, 800/ 1600 mJ for 1064 nm with several hertz Rep.rate.
CNI lasers:
LPS-L-532/ 1~450 mJ/ 1~10 Hz LPS-M-1064/ 1~10 J/ 1~20 Hz
LPS-L-1064/ 350~1000 mJ/ 1~10 Hz  
 
 Laser for Surgery
   

Laser surgery uses laser light to remove diseased tissues or treat bleeding blood vessels. Laser surgery may also be used to remove wrinkles, sunspots, tattoos, or birthmarks.
Areas of application:  
Oncology (cancer treatment) Varicose veins
Gallstones Lithotripsy
Urological surgery Gynecological surgery
Common wavelengths:  
447 nm, 532 nm, 561 nm, 577 nm, 635 nm, 810 nm, 980 nm, 1064 nm, 1320 nm, 1470 nm...
Especially the double pulsed frequency doubling laser type with 532 nm and 1064 nm combined for 120 mJ/ 160 mJ of single pulse energy, 240/ 320 mJ of double pulse energy.
