Portable electro-optic Q-switched laser skin therapeutic instrument

Abstract

The invention discloses a portable electro-optic Q-switched laser skin therapeutic instrument, which comprises a host computer and a pluggable handpiece arranged on the host computer, wherein the handpiece is electrically connected with the host computer; the portable electro-optic Q-switched laser skin therapeutic instrument comprises a host computer and a pluggable handpiece arranged on the hostcomputer. A handpiece includes an electro-optically Q-switched laser, an electro-optically Q-switched laser comprises: laser oscillation module, laser amplifier module, an electro-optic Q-switched control module is arranged in the laser oscillation module, a laser amplification module is arranged on one side of the laser oscillation module, and a laser steering device is arranged on one side of the laser oscillation module and the laser amplification module for reflecting the laser output from the laser oscillation module to the laser amplification module. The invention automatically calibrates and refreshes the background parameters of the display control module of the therapeutic apparatus by replacing the voltage memory identification module matched with the handpiece, thereby realizing the optimal calibration of the laser parameters of the therapeutic apparatus. The fault maintenance is simplified to the maximum extent, and unnecessary troubles are avoided for the users in the process of using the instrument.

Description

technical field [0001] The invention relates to the field of laser therapeutic instruments, in particular to a portable electro-optic Q-switched laser skin therapeutic instrument. Background technique [0002] With the development of laser technology, a new applied discipline - laser medicine has gradually formed. The unique advantages of laser have solved many problems that traditional medicine cannot solve in basic research and clinical application, which has attracted the attention of medical circles at home and abroad. . [0003] In the field of medical skin treatment, Q-switching (Q value--defined as the ratio of the total energy stored in the laser resonator cavity to the energy consumed per unit time in the cavity) laser is used in pigmented moles such as tattoos, spots, stretch marks, and Ota spots. , Acne scars, shrink pores, small skin wrinkles and skin rejuvenation are used more and more, and the effect is remarkable in most treatments. At present, there are mai...

AI Technical Summary

Problems solved by technology

These two therapeutic instruments have their own advantages and disadvantages: the vertical type has the advantages of large energy, and the output treatment of the light guide arm is relatively light, but the beam transmission efficiency is low, the instrument is heavy, and it is inconvenient to move and maintain; although the portable type has relatively low energy, However, the laser pulse is narrow and the peak power is high, which is convenient for movement and operation

) active Q-switching method, since the Q-switching switch is activated by the laser radiation itself, no high-voltage fast electro-optical driver or radio frequency modulator is required, although it has the advantages of simple design, small size, and relatively low cost; but the external control performance The accuracy is low, the output energy is lower than that of electro-optic Q-switched lasers, and the electro-optical conversion efficiency is low due to the large residual absorption loss of saturable passive Q-switches

Passive Q-switched laser therapy instrument usually adopts a larger-sized single-lamp single-rod design in the handpiece in order to obtain a larger laser energy output. Under high energy and high Q value loss, the Q-switching state is poor and the pulse width is not fixed. , poor pulse energy output stability

Therefore, the treatment for skin diseases is not as effective as actively Q-switched lasers

[0005] In addition, most of the portable Q-switched laser therapy instruments currently on the market require cumbersome debugging and parameter calibration after replacing the hand piece, and even need to return the whole machine to the factory for maintenance, which brings trouble and inconvenience to users.
