The role and principle of semiconductor laser therapeutic apparatus
The low-intensity laser therapy provided by the semiconductor laser device can trigger a series of biochemical reactions within the body, helping to restore and enhance normal physiological functions, particularly through improved blood circulation. This treatment has proven highly effective in reducing post-surgical inflammation and pain. The device is not only safe and easy to use but also delivers remarkable therapeutic results, making it an essential tool in modern clinical practice.
**Anti-inflammatory Effect**
The SUNDOM-300IB semiconductor laser therapy machine stimulates immune cells such as T-cells, B-cells, and macrophages, prompting them to release cytokines. This activates the immune system via lymphocyte recirculation, enhances macrophage activity, and improves both non-specific and specific immunity. Additionally, it helps reduce inflammation-related pain by modulating the inflammatory response.
**Improving Local Blood Circulation**
By directly targeting areas with reduced blood flow or indirectly irradiating sympathetic ganglia that control these regions, the semiconductor laser increases blood flow. This promotes the metabolism of pain-inducing substances and helps alleviate discomfort.
**Activation of the Endorphin System**
Exposure to semiconductor laser light can boost brain peptide metabolism and increase the release of endogenous opioids, which naturally help relieve pain.
**Inhibition of Nervous Conduction**
The laser reduces the speed, intensity, and frequency of nerve impulses caused by pain stimuli. This effectively dampens the transmission of painful signals throughout the nervous system.
**Activation of the Downstream Suppression System**
Laser irradiation stimulates the spinal cord’s posterior horn, activating a natural pain suppression mechanism that further aids in pain relief.
**Tissue Repair**
Semiconductor laser therapy promotes the formation of new blood vessels and granulation tissue, stimulates protein synthesis, and accelerates wound healing. The development of capillaries is crucial for tissue repair, ensuring adequate oxygen supply and supporting the maturation of repair cells, while also facilitating collagen production and crosslinking.
**Biological Regulation**
Laser exposure enhances immune function, regulates hormone levels, and supports balanced blood cell activity, offering a dual regulatory effect on the body’s internal systems.
**Working Principle and Features of Semiconductor Lasers**
A semiconductor laser operates through an excitation process where electrons transition between energy bands, emitting light. The crystal's cleavage plane forms two parallel mirrors, creating a resonant cavity that amplifies and outputs the laser. These lasers are known for their compact size, lightweight design, high reliability, low power consumption, and efficiency.
Semiconductor laser packaging differs from traditional discrete device packaging. While the latter primarily protects the die and ensures electrical connections, laser packaging must also manage optical output, making it more complex. It combines both electrical and optical functions, requiring specialized techniques to ensure optimal performance and stability.
