Description

Technical Field

[0001] This invention relates to the technical field of laser therapy, and more particularly to an intelligent laser therapy handpiece. Background Technology

[0002] Traditional laser therapy handpieces use only a fixed-size front protective lens, lacking an adaptive light transmission adjustment structure within the optical path. The laser spot size cannot dynamically change with the treatment distance, resulting in a constant spot diameter after the device leaves the factory. Similar products on the market rely solely on fixed lenses for laser focusing. When too close to the skin, the laser energy is highly concentrated, easily causing low-temperature burns; at greater distances, the laser energy disperses, significantly reducing the therapeutic penetration effect. Furthermore, most existing handpieces use a dual-distance sensor synchronous triggering logic, requiring simultaneous detection of the human body on both sides before laser output. If one side of the handpiece is in contact with the skin while the other is suspended, the device will lock the light output, greatly reducing the flexibility of handheld operation and making it difficult to adapt to narrow, curved treatment areas such as joints and the face. In addition, traditional devices lack a closed-loop feedback adjustment structure, unable to correct the light transmission aperture in real time. Over long-term use, accumulated mechanical gaps lead to a continuous deterioration in spot uniformity.

[0003] Existing technologies lack an integrated control scheme that can trigger light with a single sensor and adaptively adjust the light transmission range according to the detection distance. This makes it difficult to balance ease of operation and safety for skin use, and it is also difficult to achieve dynamic and balanced control of light spot energy density. Summary of the Invention

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0032] Example 1 Reference Figures 1-9The first embodiment of the present invention provides an intelligent laser therapy handpiece, including a handpiece body 100, a laser component 200 and a main control component 300. The three components work together to achieve laser therapy output, real-time distance sensing, intelligent focus compensation and adaptive adjustment of light transmission aperture, and specifically solve the problems of fixed focal length and non-adjustable spot size of traditional laser therapy handpieces.

[0033] Furthermore, the handle body 100 serves as the gripping, support, and protection unit for the entire device, providing a sealed installation space for internal optical and electrical components while ensuring comfort and safety during handheld operation. In this embodiment, the handle body 100 includes a housing 101, a tubing component 102 located at the rear end of the housing 101, and a contact housing 103 located at the front end of the housing 101. The housing 101 is integrally molded from an insulating medical-grade material with an anti-slip surface treatment for comfortable grip. The tubing component 102 integrates power supply lines, cooling lines, and signal transmission lines, all uniformly led out from the rear end of the handle to avoid cluttered wiring interfering with operation. The contact housing 103 is a protective structure for the front light-emitting area.

[0034] Preferably, the housing 101 includes an end housing 1011 and a handle housing 1012 integrally formed with the end housing 1011. An installation space is formed within the end housing 1011 and the handle housing 1012. A protective housing 1013 for mounting the laser component 201 is provided within the installation space. A connecting end 1014 connected to the protective housing 1013 is provided on the contact housing 103. A light-transmitting window corresponding to the lens component 202 is opened on the contact housing 103. A protective lens body 1015 is provided within the light-transmitting window, and a light transmission range changing component 400 is provided within the light-transmitting window. The protective housing 1013 provides an independent protective cavity for the laser core component, further isolating contamination and ensuring optical path stability. The protective lens body 1015 covers the outside of the light-transmitting window, ensuring laser transmission while blocking external foreign objects. The light transmission range changing component 400 can flexibly adjust the effective light-transmitting aperture of the light-transmitting window, thereby changing the size and energy density of the therapeutic spot.

[0035] Furthermore, the laser component 200 is the core output unit of the physiotherapy function, used to generate and output physiotherapy laser with specified parameters, and at the same time monitor the operating distance in real time to provide data basis for intelligent adjustment. In this embodiment, the laser component 200 includes a laser component 201 disposed in the housing 101, a lens component 202 disposed at the front end of the laser component 201, and distance monitoring components 203 disposed on both sides of the lens component 202. A light transmission range changing component 400 is disposed on the laser component 201.

[0036] The laser component 201 generates a stable therapeutic laser beam, which is collimated and focused by the lens component 202 and emitted from the front window to act on the human body treatment area. The light transmission range changing component 400 can change the focal length and spot shape of the laser to adapt to the focusing requirements under different operating distances. The distance monitoring components 203 arranged symmetrically on both sides can collect dual-path distance data from the front end of the handle to the skin of the treatment area in real time. This can not only calculate the average operating distance, but also identify the tilt angle of the handle, providing accurate data support for subsequent compensation and adjustment.

[0037] Preferably, the laser component 201 includes a laser emitting source 2011 disposed within a protective housing 1013, an assembly base 2012 disposed at the front end of the laser emitting source 2011, and a through-hole 2013 formed at the center of the assembly base 2012. A lens component 202 is coaxially fixedly sleeved on one end of the assembly base 2012, with the central optical path channel of the lens component 202 coinciding with the through-hole 2013. The front end of the lens component 202 is arranged facing the light transmission range changing component 400. The lens component 202, the laser component 201, and the light transmission range changing component 400 are coaxially arranged along the same central optical axis. The assembly base 2012 provides a precise installation positioning reference for the lens component 202, and the central through-hole 2013 completely coincides with the optical path channel, which can minimize laser energy loss.

[0038] Preferably, the distance monitoring component 203 includes a distance sensing module 2031 disposed on both sides of the lens component 202 and a signal feedback module 2032 disposed on the distance sensing module 2031. A signal receiving module extends out from the front end of the distance sensing module 2031, and a mounting hole for installing the signal receiving module is provided on the protective housing 1013.

[0039] The dual-channel distance sensing module 2031 is symmetrically arranged on both sides of the optical axis, which can simultaneously collect distance data between two points and calculate the tilt deflection of the handle by the difference, thus achieving higher detection accuracy. The signal feedback module 2032 can transmit the collected distance data to the main control unit 301 in real time, with a fast response speed. The mounting hole provides a positioning mounting position for the signal receiving module, ensuring accurate signal transmission and reception direction.

[0040] Furthermore, the light transmission range changing component 400 is an adjustment structure for the diameter of the light outlet aperture 2013. It adjusts the light transmission aperture by the coordinated extension and retraction of multiple tightening plates 403, thereby adjusting the light spot size. In this embodiment, the light transmission range changing component 400 includes a tightening ring 401 disposed behind the light transmission window, a tightening groove 402 formed on the tightening ring 401, and a plurality of tightening plates 403 disposed on the tightening ring 401. The tightening plate 403 includes a main plate 4031 and a concave plate 4032 connected to the main plate 4031. The shape of the plate 4032 matches the shape of the tightening groove 402, and each main plate 4031 is connected to the upper end of the concave plate 4032; the tightening ring 401 provides a mounting base for the overall adjustment structure, and the tightening groove 402 provides a sliding guide for the tightening plate 403; multiple tightening plates 403 are evenly arranged around the circumference of the tightening ring 401, and the concave plate 4032 slides in the tightening groove 402, with good synchronization of expansion and contraction. After being folded up, the edges of each plate are tightly fitted, which can form circular light-transmitting holes of different diameters. A control component 404 is provided on the tightening ring.

[0041] Preferably, the control component 404 includes a slider 4041 slidably connected to the tightening ring 401, a crossbar 4042 disposed on the slider 4041, a pull block 4043 slidably connected to the tightening ring 401, an inclined groove 4044 disposed at the lower end of the pull block 4043, and a mating strip 4045 disposed on the tightening ring 401 that cooperates with the inclined groove 4044. There are two pull blocks 4043. The two ends of the crossbar 4042 are slidably connected to the two pull blocks 4043 respectively. The pull blocks 4043 are connected to the main board 4031. When the slider 4041 slides circumferentially along the tightening ring 401, the crossbar 4042 drives the pull blocks 4043 on both sides to move synchronously. The inclined groove 4044 of the pull block 4043 slides along the fixed mating strip 4045, converting the circumferential motion into radial extension and retraction motion, which drives the tightening plate 403 to extend and retract radially along the tightening groove 402, thereby realizing the adjustment of the light transmission aperture.

[0042] Preferably, each mainboard 4031 has a sliding groove on its side wall, within which a sealing plate 4046 is slidably connected. A sealing element is provided between the sealing plate 4046 and the sliding groove, and a sealing layer is provided between the tightening plate 403 and the tightening groove 402. Adjacent tightening plates 403 are sealed by overlapping with the sealing plate 4046, the sealing element fills the gap, and the sealing layer in the tightening groove 402 seals the sliding gap, ensuring that the area around the light-transmitting zone is completely sealed throughout the process. This effectively prevents external dust from entering the internal optical path through the adjustment gap, avoids dust accumulation on the lens affecting the light output quality, and improves the overall dustproof and waterproof rating of the device.

[0043] Preferably, each slider 4041 extends a connecting rod 500, and a rotation center 501 is rotatably connected within the installation space. Pull rods 502 are rotatably connected to both ends of the rotation center 501, and the two pull rods 502 are arranged parallel to each other. A central rod 503 is provided at the end of each pull rod 502. A sleeve 504 is provided at the lower end of the connecting rod 500, and the sleeve 504 is sleeved with the central rod 503. A first magnetic attractor 505 is slidably connected to the central rod 503 near the sleeve 504. A second magnetic attractor 506 is provided inside the sleeve 504. The first magnetic attractor 505 is electrically connected to the signal receiving module and controls the magnetization of the first magnetic attractor 505. A first motor connected to the rotation center 501 is provided within the installation space. The first motor drives the rotation center 501 to rotate, causing the pull rods 502 at both ends to swing synchronously. Through the sleeve 504 and the connecting rod 500, the slider 4041 slides along the tightening ring 401, realizing the electric adjustment of the aperture. After the first magnetic 505 and the second magnetic 506 are attracted, the connecting rod 500 can cooperate with the central rod 503, so that the central rod 503 can control the position of the connecting rod 500. If the first magnetic 505 and the second magnetic 506 are not attracted, the movement of the central rod 503 will not drive the movement of the connecting rod 500, thereby realizing the position control of the single-sided tightening plate 403 and precisely adjusting the light transmission range.

[0044] Furthermore, in this embodiment, the main control component 300 is integrally embedded in an independent, enclosed mounting cavity inside the housing 101. This mounting cavity is located on the rear side of the laser component 201 and is coaxially separated from the optical path of the lens component 202. The main control component 300 comprises three main parts: a main control unit 301, a parameter storage module 302, and a feedback drive module 303. The main control unit 301 is the embedded computing core of the entire machine. The parameter storage module 302 achieves bidirectional read / write data interaction with the main control unit 301 via an SPI high-speed bus. The feedback drive module 303 integrates two independent, isolated drive channels. The first drive channel is electrically connected to the first motor of the light transmission range changing component 400, and the second drive channel is connected in series to the main power supply circuit of the laser emission source 2011.

[0045] Preferably, the main control unit 301 integrates a distance signal acquisition unit, a first-order filtering unit, a multi-condition judgment unit, a light transmittance calculation unit, a closed-loop feedback correction unit, and a hardware safety interlock unit. The distance signal acquisition unit is equipped with two independent ADC acquisition channels, and the two channels are electrically connected one-to-one to two sets of distance sensing modules 2031 through the signal feedback module 2032.

[0046] Furthermore, the parameter storage module 302 uses a non-volatile memory chip, with four types of calibration parameters internally partitioned and fixed: 1. Threshold for effective human body distance range (lower limit 10mm, upper limit 50mm); 2. Distance-transmitting aperture linear mapping parameter; 3. Aperture closed-loop feedback compensation coefficient; 4. Threshold for safe continuous irradiation time for a single part.

[0047] When this intelligent laser therapy handpiece performs body surface therapy, the core control rule is that if either of the two distance sensing modules 2031 detects the effective distance to the human body, it can activate the light transmission adjustment and laser output. Throughout the process, only the light transmission range changing component 400 is linked for control. The detailed step-by-step execution logic is as follows: S1 Dual-channel distance synchronous acquisition and digital filtering preprocessing The main control unit 301 triggers the distance signal acquisition unit at a fixed clock frequency of 50Hz to synchronously acquire real-time data from two distance sensing modules. The two sensors output raw distance values ​​L1 (left sensor) and L2 (right sensor), respectively. The raw analog signals are converted into digital signals by an ADC and then sent to a first-order filtering unit to perform debouncing calculations. The core calculation formula for filtering is as follows:

[0048] In the formula L raw L represents the original sampled value for this period. last L is the output value of the previous filter cycle. out This is the effective filtering distance value for this cycle; the two channels output L after independent filtering. out1 L out2 The signal is sent to the multi-condition judgment unit; the filter setting anti-shake latch logic is as follows: if a single sample jumps out of the effective range, the state switch is not immediately judged. The same state must be maintained for three consecutive 50Hz sampling cycles before the judgment flag is updated to avoid false triggering / false light-off caused by a finger quickly swiping or clothing momentarily blocking the light.

[0049] S2 multi-level condition judgment (working mode can be triggered as long as a single channel is valid). The multi-condition determination unit simultaneously reads the filtering distance L of the two channels. out1 L out2 The system performs three levels of conditional checks, outputting status flags at each level. First-level basic condition: Determining the effective distance interval Preset effective human detection range: 10mm≤L≤50mm; for L respectively out1 L out2 Perform interval judgment and generate two independent valid flags Flag1 and Flag2; Flag1=1 means that the left sensor has detected a human body, and Flag1=0 means that there is no human body; Flag2 is the same.

[0050] Level 2 Triggering Overall Condition Determination Set the overall trigger enable flag to Work. Flag If Flag1=1 or Flag2=1 → Work Flag =1, enter the physiotherapy workflow; if Flag1=0 and Flag2=0 → Work Flag =0, enter the whole machine standby process.

[0051] Third-level branch conditional routing 1. Standby Branch (Work) Flag =0): The main control unit directly sends a reset command to the feedback drive module, controlling the first motor to drive the tightening plate to fully open to the maximum light-transmitting aperture; the power supply circuit of the laser emission source 2011 is locked and cut off by the hardware safety interlock unit, and the whole machine enters low-power sleep mode, with only the distance acquisition unit continuing to run; 2. Work Branch Flag =1): Automatically enters the aperture calculation process, distinguishing between "single-path effective" and "dual-path effective" sub-branches to calculate the reference distance separately: Sub-branch 1: Only single-path Flag is 1, directly taking the filter value of that path as the reference distance L. base Sub-branch 2: Both Flags are 1, and the average of the two filtered values ​​is used as the baseline distance.

[0052] S3 target transmittance aperture calculation + closed-loop difference correction The transmittance calculation unit reads the reference distance L from the branch output. base Retrieve the distance-aperture linear mapping parameters from the parameter storage module, and linearly calculate the theoretical target aperture D. target The closed-loop feedback correction unit synchronously reads the current actual aperture D returned by the built-in position potentiometer of the light transmission range change component. real Calculate the aperture difference ΔD=D target -D real ; 1. ΔD=0: The current light transmission size perfectly matches the target, and no output compensation drive is required; 2. ΔD>0: The current aperture is too small. Output a positive compensation pulse to control the first motor to drive the tightening plate to open outward and expand the light transmission range. 3. ΔD < 0: The current aperture is too large. Output a reverse compensation pulse to control the first motor to drive the tightening plate to shrink the light transmission range. The number of compensation pulses is proportional to the difference ΔD, realizing stepless continuous adjustment without any gear jump.

[0053] S4 full-process dynamic cyclical update and multi-layer safety interlock control During physiotherapy, the main control unit continuously executes the entire S1~S4 process at 50Hz, dynamically adjusting the light transmission range in real time based on the distance of the handpiece. Simultaneously, the safety interlock unit performs three layers of uninterrupted protection checks: 1. Human body loss protection check: If Flag1 and Flag2 are both set to 0 within 6 consecutive sampling cycles, the shutdown interlock is immediately triggered, cutting off the laser power supply; 2. Close-range burn protection check: When L... base When the diameter is less than 20mm, the laser output power level is simultaneously reduced, and the target aperture is forcibly reduced to decrease the energy density per unit skin. 3. Overtime protection judgment: The independent timing unit continuously accumulates the duration T of a single continuous irradiation. When T reaches the preset safety threshold of parameter storage module 302, the laser output is forcibly cut off, the aperture remains unchanged, and the laser can be restarted only after the handle is released and the human body is re-detected. When any layer of safety conditions is triggered, the laser power supply is cut off first, and then the light transmission mechanism is reset. The safety priority is higher than the light transmission adjustment logic.

[0054] Operation process: Before use, check the appearance of the handle and the cleanliness of the protective lens 1015. Connect the main unit of the device to the power supply line through the rear pipeline 102 and turn on the device to complete the system self-test. Hold the handle housing 1012 and point the front end of the housing 103 toward the skin area to be treated, maintaining a roughly vertical operating posture.

[0055] After the physiotherapy program is started, the laser emission source 2011 generates a physiotherapy laser, which is collimated and focused by the mounting base 2012 and the lens 202 and then emitted from the light-transmitting window; at the same time, the distance sensing modules 2031 on both sides are activated to collect the dual-channel distance data from the handle to the skin surface in real time, and transmit it to the main control unit 301 through the signal feedback module 2032.

[0056] After filtering the distance data, the main control unit 301 calculates the reference distance and deflection angle, calls the mapping parameters in the parameter storage module 302, and calculates the target focusing amount, deflection compensation amount, and target light-transmitting aperture value. These three parameters are then simultaneously sent to the feedback drive module 303. The feedback drive module 303 outputs a drive signal, which on one hand controls the light-transmitting range changing component 400 to adjust the laser focal length, ensuring the focus falls on the skin treatment layer; on the other hand, it drives the first motor to rotate, which in turn drives the slider 404 via the rotation center 501, pull rod 502, and connecting control rod 500. 1. Sliding, in conjunction with the transmission of the pull block 4043 and the inclined groove 4044, drives the tightening plate 403 to extend and retract radially, coarsely adjusting the light-transmitting aperture; after the first magnetic suction member 505 and the second magnetic suction member 506 are attracted, the connecting control rod 500 can cooperate with the central rod 503, so that the central rod 503 can control the position of the connecting control rod 500. If the first magnetic suction member 505 and the second magnetic suction member 506 are not attracted, the movement of the central rod 503 will not drive the movement of the connecting control rod 500, thereby realizing the position control of the single-sided tightening plate 403 and precisely adjusting the light-transmitting range.

[0057] During the physiotherapy process, the distance monitoring device 203 continuously feeds back real-time distance data, and the main control unit 301 dynamically calculates and corrects it in real time, forming a closed-loop control. When the operating distance is reduced, the aperture is automatically reduced and the focus is adjusted to avoid excessive energy. When the distance is increased, the aperture is automatically enlarged and the focus is adjusted to ensure sufficient energy. When the handle is tilted, the deflection deviation is automatically compensated to ensure uniform light spot energy.
