[0002] In recent years, with the continuous development of laser technology, lasers of various wavelengths have been used more and more widely in the treatment of human diseases.

[0003] Laser applications in medicine fall into three main categories: laser life science research, laser diagnosis, and laser therapy. Laser therapy involves irradiating the skin with laser light.

[0033] Amplifier U2 is used to amplify the electrical signal output by the probe; capacitors C1 and C2 are used to filter the power supply VCC to suppress interference signals; capacitor C4 and resistor R4 form a filter circuit, which is used to filter the output signal of the infrared temperature measurement module to avoid clutter interference.

[0036] The working principle of the temperature detection circuit in this embodiment is:

[0037] When the doctor holds the handle to perform laser treatment on the patient, he or she aims the treatment head 6 at the front end of the handle at the affected part of the patient's skin. Then, the auxiliary bracket can be used to fix the handle body 1 so that the handle remains in the current position and angle, and the display screen 3 faces the doctor. After turning on the power, the laser output by the laser host is transmitted to the handle through the optical fiber, and the laser is emitted from the light outlet 4 at the front end of the handle. The laser passes through the lens in the treatment head 6 and irradiates the skin. The lens plays the role of diffusing the light beam.

[0038] When the laser irradiates the patient's skin, the skin temperature rises, and the probe of the infrared temperature measurement module 15 can sense the infrared signal radiated outward from the skin and output an electrical signal of corresponding intensity. The electrical signal output by the probe is amplified and filtered by the amplifier U2 and then output to the main control chip U3.

[0039] After receiving the electrical signal output by the infrared temperature measurement module 15 , the main control chip U3 processes the electrical signal to obtain a temperature value; then the main control chip U3 communicates with the display control chip U4 and sends the temperature value to the display control chip U4 .

[0040] The display control chip U4 sends a corresponding control signal to the display screen 3, causing the display screen 3 to display the temperature value.

[0041] In this way, the doctor can see the patient's skin temperature in real time through the display screen 3 on the handle, so as to move the position of the handle or adjust the output power of the laser host in time to avoid laser burns to the patient, thereby improving the safety of using the laser treatment handle.

[0042] like Figure 3 and Figure 4As shown, in this embodiment, because the infrared temperature measurement module 15 is located outside the outlet, the axis of the probe does not coincide with the axis of the light outlet 4 and the lens, and the probe has a limited sensing range. When the treatment area is large or the vertical distance between the treatment head 6 and the treatment area is long, the probe may only sense a portion of the treatment area, while the rest of the treatment area may not be detected. In this case, the temperature detected by the infrared temperature measurement module 15 may not be the highest temperature in the treatment area, resulting in the high-temperature area not being detected in time, posing a certain safety hazard.

[0043] In this embodiment, a rotating ring 5 is mounted on the front end of the handle, and an infrared temperature measurement module 15 is fixed to the rotating ring 5. After the sleeve 7 at the rear end of the treatment head 6 is connected to the rotating ring 5, and with the handle body 1 secured by the auxiliary bracket, the infrared temperature measurement module 15 can be driven to rotate synchronously around the circumference of the light outlet 4 by rotating the treatment head 6. In this way, the physician can remain seated without moving, observing the temperature value displayed on the display screen 3 while rotating the treatment head 6. During the rotation of the treatment head 6, the probe detects different parts of the treatment area, and the temperature value on the display screen 3 changes during the rotation. In this way, the highest temperature in the treatment area can be detected and displayed, avoiding missed detections.

[0044] The above-mentioned rotation detection mode is recommended to be used when the treatment area is large or the distance between the treatment head 6 and the affected area is far.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
