Problems solved by technology

[0003] The stronger the power density and energy density of the laser at the irradiation site, the stronger its penetrating power, and more light can reach the surface of the spinal cord. However, the tissue temperature at the irradiation site has a linear relationship with the output energy. When it exceeds a certain energy value, it will cause tissue thermal injury
Most of the existing weak laser treatment equipment is applied to superficial tissues, and when deep tissue is irradiated, the existing weak laser treatment equipment cannot monitor the change of tissue temperature at the irradiation site
Especially in the case of a fixed spot area, the greater the power density and energy density, the more light energy can penetrate deep tissue, but the tolerance of human tissue to temperature rise is limited, and it is easy to cause thermal damage to the irradiated part , which seriously restricts the application of weak laser in the treatment of spinal cord injury

Embodiment

[0020] In order to overcome the inconvenience in use of existing products and the pain caused to users, the present invention discloses a laser physiotherapy instrument with real-time energy feedback. Depending on the temperature resistance, the temperature adaptive method is adopted to output appropriate laser energy to treat the treatment site.

[0021] see figure 1 as well as figure 2 The laser physiotherapy apparatus of the present invention mainly includes a microprocessor, a laser treatment part (ie, a laser treatment component) and a temperature detection part (ie, a temperature detection component).

[0022] In the laser physiotherapy instrument, a laser diode and a pulse generator form a laser treatment assembly; a non-contact temperature acquisition circuit formed based on an infrared non-contact temperature sensor, a signal amplification circuit and an AD conversion circuit form a temperature detection assembly; a microprocessor (Model: STC89C52) completes the fu...

Abstract

The invention provides a real-time energy-feedback laser physiotherapy device, including a housing, a microprocessor, a laser therapy assembly and a temperature detection assembly. According to the invention, the temperature detection assembly detects the temperature within a laser radiation area in a non-contact manner. The microprocessor is utilized for adjusting the volume of the laser output energy. Through the energy-feedback adjustment , radioactive therapy on deep portions of the spinal cord of a user is conducted with no heat damage. The device herein overcomes the failure of prior products in adjusting laser irradiation energy in real time due to incapability of monitoring variations of the temperature of a radiated part of the body, and thus guarantees the effectiveness and safety of the therapy.

Description

technical field [0001] The invention relates to an intelligent nerve tissue repair and regeneration device, in particular to a real-time energy feedback laser physiotherapy instrument. Background technique [0002] Repair of spinal cord injuries remains a major challenge in the field of neuroregenerative science. As a safe, effective, and side-effect-free treatment, weak laser irradiation therapy has shown its unique biological stimulation in the rehabilitation of peripheral nerves in recent years, and it can promote the regeneration of damaged nerves. In the treatment of spinal cord injury, due to the deep location of the spinal cord, a laser band with strong penetrating power is required. The laser penetrates the superficial tissue and reaches the surface of the spinal cord to exert its unique photobiological stimulation effect. [0003] The stronger the power density and energy density of the laser at the irradiation site, the stronger its penetrating power, and more lig...
