Typical Applications of Uniform Beam 650nm Red Line Laser Module In Medical Field

When formally available 650nm wavelength red laser light source is used in medical field, cooperated with a qualified 650nm red laser diode and a qualified optic lens, it is manufactured into a professional tool of a uniform beam 650nm red line laser module. Even though sometimes it is selected with lower power of less than 5mW, however, it still gets quite high biological safety. This laser light source gets moderate penetration depth of about 0.5 to 2nm, low risk of damage to human tissue, and meet the safety standards of medical equipment, such as FDA Class IIIa.

In practical medical treatment works, only after easy connects with an AC/DC adapter, 650nm red line laser module projects non Gaussian distribution red laser light at several miles far away. Being made with a qualified separate crystal lens, the visible red straight line is convenient for doctors to observe directly with the naked eyes and adjust the operation direction in real time. Especially in minimally invasive surgery, the use of a laser line generator can reduce the dependence on auxiliary equipment such as microscopes and improve positioning efficiency (such as path marking for puncture surgery).

For the most important of all, when uniform beam 650nm red line laser module is pointing onto treatment parts, non Gaussian red laser beam can avoid tissue thermal damage caused by excessive energy in the center of Gaussian light. The uniform straight red reference line can achieve larger area, low intensity gentle irradiation, such as uniform analgesia during physical therapy, while ensuring the clarity of the marking line. On the basis of required line length, line fineness and work distance from beam aperture to treatment tissue parts, this red laser line generator should be selected with correct output power and Powell lens fan angle, thus it makes sure of efficient line marking as expected.

General use of uniform beam 650nm red line laser module in medical treatment:

Assisted positioning in surgical operations: In orthopedic surgery (such as fracture reduction and plate fixation), the surgical incision or bone correction direction is marked by projecting a red straight alignment laser line to assist doctors in precise operation. It is also used for linear guidance of skin incisions in plastic surgery (such as double eyelid surgery and scar repair).

Physical therapy and rehabilitation treatment: Low-power red laser line generators are used for acupoint irradiation therapy (such as traditional Chinese medicine laser acupuncture). The uniform energy distribution of non-Gaussian red laser beams can avoid local overheating and improve treatment comfort, which can also be used for motion trajectory guidance of rehabilitation equipment, such as linear motion reference during limb function training.

Medical testing and imaging: As an auxiliary light source for skin detectors (such as color spots and blood vessel distribution detection), when the straight line beam scans the skin surface, the uniform energy distribution can reduce the interference of reflected light spots and improve image clarity. Red alignment laser line source is also used for linear marking of lesions in some endoscopic equipment.

Dental diagnosis and treatment: In dental implants and orthodontic treatment, 650nm red line laser is projecting a straight line assists in determining the implant angle or the installation position of the braces, improving the accuracy of the operation; it can also be used for the spot calibration of dental laser therapeutic devices.

Advantages: Uniform beam 650nm red line laser module gets the miniaturized metal packaging structure is suitable for the compact space of medical equipment (such as surgical robot arms, portable physiotherapy devices), and the driving circuit has strong anti-interference ability, which can be seamlessly connected with medical control systems (such as PLC, touch screen). Comparing with infrared lasers (such as 808nm) or ultraviolet light sources, 650nm red alignment lasers are cheaper and do not require special protective measures (such as goggles), which reduces the R&D and use costs of medical equipment and is suitable for popularization in primary medical scenarios.
