The efficacy and function of semiconductor laser therapy device

As a mature physical therapy device, the core principle of semiconductor laser therapy device is to use low-intensity laser with specific wavelengths (commonly 635nm-980nm red to near-infrared light) to irradiate human tissues. It does not produce high-temperature cutting or burning effects, but instead generates a series of positive biological effects through photobiological regulation, thereby achieving the goal of treatment and rehabilitation.

Main efficacy and mechanism of action:

Analgesia and anti-inflammatory:

Function: Effectively relieve various types of acute and chronic pain, such as arthritis, muscle strain, neuralgia, postoperative pain, etc.

Mechanism: Inhibit the activity of pain signaling substances (such as bradykinin and serotonin); Promote the release of analgesic substances such as endorphins by the human body itself; At the same time, by reducing tissue congestion and edema, lowering inflammatory mediators, the anti-inflammatory effect is achieved.

Promote tissue repair and wound healing:

Function: Accelerate the healing of ulcers, bedsores, surgical incisions, and burn wounds; Promote the formation of callus after fracture.

Mechanism: Laser energy can be absorbed by cellular mitochondria, enhancing cellular metabolism and increasing ATP (energy) synthesis. This can stimulate fibroblast proliferation, accelerate collagen synthesis and angiogenesis, thereby promoting granulation tissue growth and epithelial regeneration.

Improving blood circulation:

Function: Relieve local swelling and provide more nutrition and oxygen to damaged tissues.

Mechanism: Laser irradiation can dilate microvessels, reduce blood viscosity, enhance red blood cell deformability, and significantly improve local microcirculation.

Regulating immune function and reducing edema:

Function: Assist in regulating local immune response, accelerate exudate absorption, and eliminate edema.

Mechanism: Acting on immune cells (such as macrophages and lymphocytes) to enhance their phagocytic function; By increasing lymphatic reflux, promote interstitial fluid absorption.

Neural repair and functional regulation:

Function: Used to assist in the treatment of facial neuritis (facial paralysis), peripheral nerve injury, etc.

Mechanism: Stimulate Schwann cell activity, promote nerve myelin regeneration and axonal growth, and accelerate the recovery of damaged nerve function.

Clinical application areas:

Rehabilitation Medicine Department/Pain Department: Cervical spondylosis, lumbar disc herniation, shoulder periarthritis, knee arthritis, soft tissue injury, chronic pain syndrome.

Dermatology/Burn Department: Skin ulcers, postherpetic neuralgia, eczema, dermatitis, burn wounds.

Stomatology: Oral ulcers, periodontitis, dry socket disease, peri implantitis, temporomandibular joint disorders.

Surgery: Poor wound healing, pressure ulcers, and thrombophlebitis after surgery.

Otolaryngology: rhinitis, pharyngitis, laryngitis, otitis media.

Neurology: peripheral facial nerve paralysis, trigeminal neuralgia, post-stroke rehabilitation.

Important precautions:

Medical device attributes: Semiconductor laser therapy devices belong to Class II or Class III medical devices and should be used under the guidance or operation of professionals.

Adjuvant therapy status: It is usually part of a comprehensive treatment plan and cannot completely replace other necessary medical methods such as medication and surgery.

Contraindications: Direct exposure to the eyes is prohibited (special protective goggles must be worn); Avoid irradiating pregnant women's abdomen, thyroid gland, malignant tumor sites, bleeding sites, and sensory impairment areas.

Selection and use: It is essential to choose products certified by the National Medical Products Administration (NMPA) and strictly follow the product instructions and medical advice.

In summary, semiconductor laser therapy is a safe, non-invasive, and painless physical therapy tool. Its core value lies in promoting self repair, pain relief, and inflammation at the cellular level through photobiological regulation. It is widely used in various clinical fields for auxiliary treatment and rehabilitation.
