Description

Technical Field

[0001] The utility model relates to the field of optoelectronic technology, specifically to optical-based medical devices, and particularly to a handpiece optical energy calibration system for a high-intensity pulsed light therapy instrument that realizes output OPT charge and discharge monitoring. Background Art

[0002] Medical high-intensity pulsed light therapy instruments emit incoherent light sources with high intensity and large energy within a specific wavelength range, and can clinically treat different lesions. During the pulsed continuous discharge process, since the energy of each capacitor discharge is very large, the voltage of the capacitor drops severely, and the capacitor energy cannot be charged to the set value within a short time during subsequent discharges, resulting in very poor discharge energy consistency. The consequences of this situation are usually that the pulse energy emitted for the first time is too large and easily burns the skin, and the subsequent pulse energy is too low to be effective for treatment.

[0003] To solve the above technical problems, Lumenis first proposed the OPT technology. OPT is also known as Optimal Pulse Technology. In fact, the OPT technology is to make the light waveform become a very uniform square wave, which can effectively control the whole treatment process, eliminate the energy peak exceeding the treatment energy at the starting part, and thus improve safety. In existing high-intensity pulsed light therapy instrument devices, due to the addition of an inductor in the circuit, the light waveform front edge is very slow. To overcome this problem, the commonly used technical means is usually to increase the conduction pulse width at the beginning of the pulse. Since the pulse width is fixed, the problem is that there will be a spike at the front edge, and the smaller the energy, the higher the spike, so it will increase the treatment hidden danger. In addition, the technical principle of this control system structure is extremely complex, the cost of circuit devices is very high, and a complex control system is required to ensure that the high-intensity pulsed light waveform forms an approximately uniform square wave.

[0004] When the pulse width is adjustable, the energy density is an important parameter affecting the curative effect. The AOPT technology is to achieve adjustable pulse width and adjustable energy density in the sub-pulse mode.

[0005] During the actual treatment process, it is necessary to flexibly control and arbitrarily combine the waveform of high-intensity pulsed light, the time of the light-emitting pulse, and the optical power, so as to improve the curative effect of patients and improve the treatment experience of patients. The energy has a positive effect in clinical medicine. Therefore, a device that can flexibly adjust the light-emitting power of a high-intensity pulsed light source is needed to have a positive effect on clinical medicine. Summary of the Invention

[0030] This embodiment provides an optical energy calibration system for the handpiece of an intense pulsed light therapeutic apparatus, which includes two parts: the handpiece and the system, as described below:

[0031] Handpiece

[0032] As shown Figure 1 and Figure 2 shown, the handpiece part includes a condenser body 1 and a xenon lamp assembly 2 disposed inside; a light guide crystal body 3 is matched with the condenser body 1; a light blocking device 6 is further disposed inside the condenser body 1, and photoelectric sensors 5 are disposed at both ends. The photoelectric sensors 5 collect the light energy signals reflected by the light blocking device 6 and transmit them to the intense pulsed light treatment instrument system.

[0033] The condenser body 1 further includes a condenser cavity 14, and the xenon lamp assembly 2 is disposed inside the condenser cavity 14. The xenon lamp assembly 2 includes a quartz tube 10 and a xenon lamp 7 disposed inside the quartz tube 10.

[0034] As shown Figure 2 shown, high-voltage insulating bakelite 19, a water-passing cover 4, photoelectric sensors 5, and a light blocking device 6 are symmetrically installed on both sides of the condenser body 1 in sequence.

[0035] A cavity 61 is disposed inside the light blocking device 6, and the light source generated by the handpiece is located in the cavity 61 inside the light blocking device 6. A light guide channel 62 communicating the cavity 61 inside the light blocking device 6 and the outside of the light blocking device 6 is disposed on the light blocking device 6. In this way, the light emitted by the light source can be emitted to the outside of the light blocking device 6 along the light guide channel 62; the number of the light guide channels 62 is the same as the number of the photoelectric sensors 5 on the light source. The photoelectric sensors 5 are fixedly disposed inside the light blocking device 6, and the photoelectric sensors 5 and the light guide channels 62 are in the same plane. A water-passing upper cover 8 is further installed on the upper side of the condenser body 1 and sealed by a large sealing ring 15 to prevent water leakage, and a light guide crystal body 3 is installed on the lower side.

[0036] A filter lens 16 and a filter recognition sensor 17 are installed on the condenser body 1.

[0037] The light guide crystal body 3 includes two TEC water-cooling plates 9 disposed on both sides of a light guide crystal clamping plate 12. A light guide crystal 13 is installed inside the light guide crystal clamping plate 12. At least one TEC 11 is further disposed on the light guide crystal clamping plate 12. In the present utility model, 4 TECs are preferably used and are symmetrically arranged in pairs on both sides of the light guide crystal clamping plate 12. And a temperature sensor 18 is installed on the light guide crystal clamping plate 12 to monitor the temperature of the light guide crystal 13.

[0038] In the present utility model, cooling water enters the water-passing front cover 4 from the water inlet 20, passes through the condenser body 1, enters the TEC water-cooling plate 9 from the water-passing rear cover 41, and flows out from the water outlet 21 on the water-passing front cover 4 to realize the cooling of the condenser body 1.

[0039] Handpiece light energy calibration system

[0040] As shown Figure 3As shown in the figure, the light energy calibration system of the handpiece of the intense pulsed light therapy instrument in the present utility model includes a power supply module, an energy monitoring module, a signal conversion module, a driving circuit and a discharge module, and a control module. The power supply module is used for power supply;

[0041] The energy monitoring module is used to monitor the light energy signal of the handpiece in the present utility model;

[0042] The signal conversion module is used to convert the light energy signal into an electrical signal and give it to the control module;

[0043] The driving circuit and the discharge module are used to receive the instructions of the control module and adjust the electrical energy supply of the intense pulsed light therapy instrument system.

[0044] The photoelectric sensor 5 and the light blocking device 6 in the handpiece of the present utility model are assembled. The photoelectric sensor 5 monitors the light energy output through the light guiding channel 62 on the light blocking device 6. The photoelectric sensor 5 converts the collected light energy into a linear analog quantity and feeds it back to the signal conversion module. The signal conversion module feeds back the converted ADC value to the control module. Through the processing of the control module, corresponding control signals are output to adjust the current of the driving circuit and the discharge module, so that the output light energy increases or decreases, thereby adjusting the output light energy, achieving controllable and stable energy intensity of the output light energy, and avoiding problems such as easy skin burns during the first emission of the light output device and ineffective treatment due to too low subsequent pulse energy.

[0045] The energy monitoring module monitors the light energy of the handpiece during the pre-ignition stage through the cooperation of the photoelectric sensor 5, the light blocking device 6 and the light blocking device 7. The light energy is evenly reflected through the reflection cavity and can be quickly received by the photoelectric sensor. The photoelectric sensor converts the received light energy into an analog electrical signal and feeds it back to the signal conversion module. The signal conversion module further feeds back the information to the control system. After processing and calculation by the control system, control signals are further output to adjust the electrical energy supply of the system, and finally the output energy is stabilized.

[0046] The photoelectric sensor 5 is assembled with the light blocking device 6. Through the processing and feedback of the signal conversion module, the entire system finally completes the signal transmission and control. The control module can be used to confirm whether the output energy of the driving circuit and the discharge module is consistent by collecting and analyzing the intensity of the light. If the output energy monitored by the driving circuit and the discharge module is inconsistent, the control module can automatically adjust the output according to the light intensity. If it still cannot be adjusted to the correct output, the control module will give an alarm, thereby reducing the risk. For the multi-channel monitoring module, the number of light guiding channels 62 on the light blocking device 6 and the corresponding photoelectric sensors 5 can be increased correspondingly to realize the functions of the system.

[0047] The control module includes a core chip with data operation and processing capabilities, which is used for the acquisition of input signals, the operation and processing of input signals, and the output of control signals, including the display of the working state of the handpiece and the acoustic and optical alarm. The core chip can be any one of an MCU, a CPU, a DSP, an ARM, a computer, etc. The input peripherals can be any one or a combination of a button, a knob, and a touch screen. The output peripherals can be any one or a combination of a display screen, an acoustic and optical alarm, a digital tube, a loudspeaker, and a display lamp.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
