Technical Field

The invention belongs to the technical field of laser treatment, and particularly relates to an infrared real-time temperature measurement treatment hand tool for assisting skin healing by laser.

Background

Scars are a condition of skin healing, thereby causing functional and aesthetic disorders that are often disabling. They are involved in excessive proliferation and collagen perturbation due to perturbation of the transforming growth gene-beta (TGF- β).

The heat of the laser improves healing by altering the inflammatory response. An increase in temperature between 45 ℃ and 53 ℃ leads to overexpression of heat shock protein 70(HSP70) and thus to a change in the expression of TGF-. beta.s. Semiconductor lasers at wavelength 810nm have proven their effectiveness, but are not suitable in objects of the dark photon type where scarring is most likely to occur.

The traditional treatment method adopts a handheld infrared temperature measuring gun to measure temperature in real time in the treatment process, so that special persons must be arranged to measure the temperature in a matched manner in the treatment process, and the defects of difficult matching and larger temperature measuring error are easy to occur when the treatment method is moved and irradiated.

The embodiment of the invention aims to provide an infrared real-time temperature measurement treatment hand tool for assisting skin healing by laser, which adopts semiconductor laser with 1210nm +/-10 nm wavelength and extremely little melanin absorption to homogenize and shape laser beams; meanwhile, synchronous and accurate non-contact temperature measurement is realized on the target tissue in the laser treatment process, and a doctor is helped to judge the treatment end point.

The concrete structure is as follows:

referring to fig. 1 to 3, fig. 1 is a schematic diagram of an infrared real-time temperature measurement treatment hand tool for laser-assisted skin healing according to an embodiment of the present invention, fig. 2 is a perspective diagram of an infrared real-time temperature measurement treatment hand tool for laser-assisted skin healing according to an embodiment of the present invention, and fig. 3 is a schematic structural diagram of an infrared real-time temperature measurement treatment hand tool for laser-assisted skin healing according to an embodiment of the present invention.

The infrared real-time temperature measurement treatment hand tool for laser-assisted skin healing comprises a laser light path system, an infrared temperature sensor, a shell structural part and a U-shaped support.

The shell structural part comprises hand tool connecting part and hand tool clamping part, and the hand tool connecting part and the hand tool clamping part are connected together through 4M 2.5 hexagon socket head cap screws. The U-shaped support is arranged below the hand tool clamping part and is connected together through 4M 2.5 cross countersunk head screws.

The laser light path system is positioned in the shell structural part and outputs working laser and aiming light of a square light spot outwards, and comprises a variable reflectivity lens, a plano-convex lens and a plano-concave lens which are all glued on a hand tool connecting part.

Fig. 5 shows an optical design schematic diagram of the infrared real-time temperature measurement treatment handpiece provided in this embodiment, and an optical path structure of the optical design schematic diagram is as follows:

the working laser and the aiming light are output through optical fiber coupling, the output end of the optical fiber is connected with a shell structural member, and the working laser and the aiming light are output outwards after being respectively polarized, shaped, collimated and focused through a variable reflectivity mirror, a plano-convex lens and a concave cylindrical lens in sequence, wherein the variable reflectivity mirror, the plano-convex lens and the concave cylindrical lens are coupled with the central axis of the optical fiber, and the light source of the working laser is a 1210nm +/-10 nm semiconductor laser.

The infrared real-time temperature measurement treatment hand tool with the structure adopts semiconductor laser with 1210nm +/-10 nm wavelength and extremely little melanin absorption to homogenize and shape laser beams; meanwhile, synchronous and accurate non-contact temperature measurement is realized on the target tissue in the laser treatment process, a doctor can be helped to judge the treatment end point, and synchronous real-time accurate temperature measurement on the target tissue of the human skin in the working laser irradiation treatment process is realized.

In the prior art, by taking the chinese patent with the application number of CN201110457724.5 and the name of a non-contact real-time temperature measurement treatment handpiece for laser fungal treatment as an example, the disclosed technical scheme adopts a mode that a laser light path and a main shaft of an infrared temperature measurement head are crossed, so that synchronous and accurate non-contact temperature measurement of a small target of a target tissue can be realized in the strong laser treatment process. However, because the focusing point treatment mode is adopted, the main shaft of the infrared temperature sensor and the cross shaft of the laser light optical path system work, and because the receiving angle of the infrared temperature measuring head is small, the large-size temperature detection cannot be realized.

In this embodiment, the infrared temperature sensor employs an integrated infrared temperature measurement probe, wherein a reference light path diagram of the integrated infrared temperature measurement probe is shown in fig. 4, and as the working distance increases, the detection range received by the infrared temperature sensor also increases. In this embodiment, the photoelectric detector, the optical system and the electronic circuit are integrated together in the metal shell, and the main shaft of the infrared temperature sensor is parallel to the laser optical path system, so that the working laser, the aiming light and the infrared temperature sensor are coaxial, the maximum receiving angle of the infrared temperature sensor is ensured, higher temperature measurement precision is realized, and the surface temperature of the target is calculated by measuring the infrared radiation intensity emitted by the target without contacting the target.

Fig. 6 and 7 are laser treatment comparison diagrams of the infrared real-time temperature measurement treatment hand tool without and with the invention, respectively, and it can be known from the diagrams that scars after the skin healing without the laser treatment are obvious, but scars after the skin healing with the laser treatment are basically invisible.
