Description

Technical Field

[0001] The present invention relates to the field of laser technology, and more specifically, to a fractional laser handpiece and a 1470nm semiconductor laser therapeutic device. Background Art

[0002] When spots, acne, wrinkles, etc. appear on the human skin surface, laser therapy devices are usually used in conjunction with fractional laser handpieces to treat the lesions on the skin surface.

[0003] Since 1470nm laser energy can be efficiently absorbed by water molecules in tissues and instantly release heat energy to produce focal photothermal effects, fractional lasers using light scanning fractional technology can create hundreds of micro-columnar coagulation products on the skin surface, triggering a rapid healing reaction, achieving the purpose of non-ablative skin surface repair such as removing spots, scars, wrinkles, and acne pits; at the same time, laser treatment can also stimulate the regeneration of skin collagen to achieve the effect of skin rejuvenation and firming.

[0004] However, traditional fractional laser handpieces do not have good laser directionality, and the emitted therapeutic light is disorderly and has large reflection losses after passing through the skin. When in use, a skin coupling agent must be applied to the affected area, and the therapeutic handpiece must be close to the coupling agent to reduce the scattering loss when the matrix enters the skin and to evenly distribute the therapeutic light on the skin. However, this structure limits efficient cooling on the skin surface, and can only use contact cooling with low cooling efficiency and inconvenient precise operation, which greatly limits the light flux during fractional laser treatment and affects the clinical treatment effect. Too high laser power and energy can easily cause skin pigmentation and thermal damage to the skin, while too low focal photothermal effect is poor, resulting in ineffective treatment and poor effect. In addition, the operator's uncontrollable technique may also lead to waste of fractional energy, shallow treatment depth, etc., affecting the cosmetic effect. Therefore, the use of fractional laser handpieces in the prior art has the technical problem of poor treatment effect. Summary of the invention

[0005] In order to solve the technical problem that the fractional laser handpiece in the prior art has poor treatment effect, the present invention provides solutions in the following aspects.

In addition, during treatment, the fractional laser handpiece is rolled along the long axis and the wide axis of the treatment area, and the length and width of the treatment area can be calculated in combination with the real-time speed measured by the speed sensor.

[0015] The beneficial effects are as follows: since the laser output module of the present invention is provided with a direct laser fiber, a ring-type laser fiber and a scattering photobiotherapy probe under the condition of setting a fractional laser handpiece, it is possible to achieve through a 1470nm semiconductor laser therapy device that not only can choose to output a point-mode laser through a direct laser fiber for controllable tissue vaporization and ablation treatment, but also can choose to output a 360-degree ring-mode laser through a ring-type laser fiber for safe tissue cavity treatment, and can also choose to output a fractional mode laser through a fractional therapy handpiece for fine light scanning skin surface repair treatment, and further choose to output a scattering mode laser through a photobiotherapy probe for efficient wound, ulcer, and wound surface photobiostimulation regulation treatment, thereby achieving the multi-mode laser treatment required for clinical medicine through a 1470nm semiconductor laser therapy device.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example of fractional laser handpiece suitable for 1470nm semiconductor laser therapeutic apparatus:

[0032] like Figure 1 and Figure 2 As shown, the fractional laser handpiece suitable for 1470nm semiconductor laser therapeutic apparatus of the present invention comprises: a cover 13, which is used to cover the skin surface when laser treatment is performed on the skin surface; an X-galvanometer 3, which is arranged inside the cover, and is used to perform laser scanning on the X axis under the drive of the X-axis motor assembly 4; a Y-galvanometer 5, which is arranged inside the cover, and is used to perform laser scanning on the Y axis under the drive of the Y-axis motor assembly 6; the X-axis motor assembly 4, which is arranged inside the cover, is used to drive the operation of the X-galvanometer; the Y-axis motor assembly 6, which is arranged inside the cover, is used to drive the operation of the Y-galvanometer; a smoke exhaust pipe 10, which is arranged inside the cover, one end of which is placed at the bottom of the cover, and the other end is connected to a negative pressure device, so as to suck out the smoke generated in the cover; a cooling pipe 11, which is arranged inside the cover, and the end of which is connected to a cooling device, is used to absorb the heat generated during laser treatment of the skin. A handle connection line interface 2 for the handle connection line to pass through, and an optical fiber connection line interface 1 for the optical fiber connection line to pass through are arranged on the top of the cover.

[0033] The cooling device in this embodiment includes: a cooling host and a refrigerant. The interior of the cooling pipe 11 is composed of two independent pipes, one is a high-pressure side pipe, and the other is a low-pressure side pipe. The working principle of the cooling pipe is based on the circulation and phase change process of the refrigerant. The refrigerant flows between the two pipes and undergoes phase change at the same time, realizing the process of absorbing heat.

[0034] In this embodiment, the X-axis is parallel to the horizontal plane, and the Y-axis is perpendicular to the horizontal plane. The cover body is made of transparent material so that medical staff can observe the inside of the cover body.

[0035] When the fractional laser handpiece of this embodiment is working, the laser 7 is first incident on the X-galvanometer handle, and the X-galvanometer refracts the laser onto the Y-galvanometer in the horizontal direction, and then the Y-galvanometer refracts the laser downward in the vertical direction to act on the patient's skin; the host control software of the laser therapeutic instrument controls the X-axis motor assembly to drive the X-galvanometer to scan along the X-axis, and the Y-axis motor assembly drives the Y-axis galvanometer to scan along the Y-axis, thereby achieving the deflection of the laser beam, so that the laser focal point with a certain power density moves according to the required requirements, thereby outputting a vector graphics laser. Before treating the patient's skin, the negative pressure device is controlled to be in operation, and the generated smoke will be discharged from the hood through the exhaust pipe; before treating the patient's skin, the cooling device is controlled to be in operation to cool the hood, thereby preventing the patient's skin surface temperature from being too high. The ratio of cold wind and smoking intensity needs to be adjusted to be suitable. If the cold wind is too strong, the smoking effect will be affected, and vice versa.

[0036] Traditional fractional laser handpieces do not have good laser directionality, and the emitted therapeutic light is disorderly and has large reflection losses after passing through the skin. When in use, a skin coupling agent should be applied to the affected area, and the therapeutic handpiece should be close to the coupling agent to reduce the scattering loss when the fraction enters the skin and to evenly distribute the therapeutic light on the skin. However, this structure limits the application of efficient cooling technology on the skin surface. Currently, only contact cooling with low cooling efficiency and inconvenient precise operation can be used, which greatly limits the light flux used for treatment and affects the clinical treatment effect. It is easy to cause side effects of treatment such as skin pigmentation and skin thermal damage. In addition, the operator's uncontrollable technique may also lead to waste of fractional energy, shallow treatment depth, etc., affecting the cosmetic effect.

[0037] The fractional laser handpiece of this embodiment is provided with a cover body to avoid energy loss when laser treatment is performed on the skin surface; by providing an X-mirror and a Y-mirror, the laser can have good directionality; the fractional laser handpiece of the present invention no longer adopts a contact cooling method, but instead cools the skin surface by providing a cooling tube to prevent excessive temperature from burning the skin, and avoids treatment side effects such as abnormal epidermal pigmentation and epidermal thermal damage; since the laser beam will generate smoke when acting on the skin, this smoke not only affects the surgical field of view, but also contains harmful substances that may cause health hazards to medical staff and patients. By providing a smoke exhaust pipe, the smoke generated during work can be absorbed in time and then discharged through the pipe to ensure the air quality in the surgical area and the smooth progress of the operation; therefore, when performing 1470nm semiconductor laser treatment on the skin surface, the fractional laser handpiece of the present invention is used to greatly improve the effect of laser treatment and ensure the safety of the treatment process.

[0038] In one embodiment, it further includes: a plurality of tracking rollers 12 disposed at the bottom of the cover body, for moving the cover body when laser treatment is performed on the skin surface.

[0039] The tracking roller can be a universal wheel.

[0040] Since the diseased area on the patient's skin may be large, a tracking roller is provided so that the fractional laser handpiece can be conveniently moved to adjust the position where the laser acts on the patient's skin.

[0041] In one embodiment, it further includes: a speed sensor 9 disposed inside the cover and connected to a control system module of the laser therapy device, for monitoring the moving speed of the cover.

[0042] The speed sensor is connected to the control system module of the laser therapy device.

[0043] Since the fractional laser handpiece needs to be moved at a constant speed when treating the skin surface, by setting a speed sensor to monitor the moving speed of the cover, the laser handpiece can be prevented from moving too fast to ensure the treatment effect. In addition, during treatment, the fractional laser handpiece is rolled along the long axis and the wide axis of the treatment area, and the length and width of the treatment area can be calculated in combination with the real-time speed measured by the speed sensor.

[0044] When using the handpiece measurement function, you must step on the foot switch of the laser therapy device and confirm that the roller of the treatment head is in continuous contact with the skin to be measured. Roll the handpiece roller in a single direction along the direction of the arrow on the area and keep it in contact to measure the length. Then press the width option to start measuring the width and repeat this procedure. After entering the length and width, the total area will be obtained and displayed in the operation interface. Click Save. Repeat this process until all areas are measured. If you need to clear the data and remeasure, you need to step on the foot switch and repeat the measurement again. Push the handpiece roller until the treatment area is fully covered. The energy will accumulate and the system will sound to remind the user that the preset energy has been reached. The coverage (%) bar will be gradually filled up to show the percentage of the target coverage (%) that has been achieved.

[0045] In one embodiment, it also includes: a speed status light 8 arranged inside the cover body, and the controlled end of the speed status light is connected to the control system module of the laser therapy device, which is used to receive the voltage signal sent by the sensor and display the status.

[0046] When the movement speed of the cover is within the preset speed range, the control system module of the laser therapy device controls the speed status light to light up. When the movement speed of the cover exceeds the preset speed range, the control system module of the laser therapy device controls the speed status light to go out. The movement speed of the cover determines the movement speed of the fractional laser spot on the skin surface. By setting the speed status light, it can prevent the laser spot from moving too fast or too slow on the skin surface during laser treatment.

[0047] 1470nm semiconductor laser therapeutic device embodiment:

[0048] like Figure 3 As shown, the present invention also provides a 1470nm semiconductor laser therapeutic device, comprising: a laser module for generating laser, a laser output module for beam shaping and coupling output of the laser generated by the laser module, and a control system module for adjusting the operating parameters of the laser module, the laser output module comprises a collimator for beam shaping the laser generated by the laser module, a laser output interface for coupling output of the laser beam, a dot matrix laser interface for connecting a dot matrix handpiece for dot matrix mode laser output, and the dot matrix laser handpiece described in the above embodiments, wherein the beam output end of the collimator is respectively connected to the laser output interface and the dot matrix laser interface, the laser output interface is used to be connected to the optical fiber connecting line of the dot matrix laser handpiece, and the dot matrix laser interface is used to be connected to the handle connecting line of the dot matrix laser handpiece.

[0049] Semiconductor laser therapy devices with a laser wavelength of 1470nm have been widely used in the treatment of multiple diseases in clinical medicine due to their advantages of simple structure, low power consumption, long life, high reliability, small size, light weight, and portability. The 1470nm infrared spectrum laser generated by it can be selectively and efficiently absorbed by water molecules in human tissues, and heat the water to expand until the cells burst to produce high-precision cutting, coagulation, vaporization, hemostasis and other therapeutic effects. It has the advantages of high tissue absorption rate, shallow penetration depth, and small thermal damage. When performing tissue resection surgery, the incision is narrow, the speed is fast, the cut surface is neat, the depth is controllable, and the thermal damage to the surrounding tissue is small. When performing intracavitary ablation surgery, it can effectively control the area where the tissue produces necrosis and avoid damage to normal tissue. When performing skin surface repair treatment, it does not ablate the skin surface, and can produce hundreds of micro-columnar coagulants to induce a rapid healing response. Therefore, it is very suitable for the treatment of tiny tissues such as skin, blood vessels, nerves, and gastrointestinal tract. It is superior to other wavelength lasers and is a very important medical laser light source.

[0050] The fractional laser handpiece of the 1470nm semiconductor laser therapy device of the present embodiment is provided with a cover body to avoid energy loss when performing laser therapy on the skin surface; since the laser beam will generate smoke when acting on the skin, this smoke not only affects the surgical field of view, but also contains harmful substances that may cause health hazards to medical staff and patients. By providing a smoke exhaust pipe, the smoke generated during work can be absorbed in time and then discharged through the pipe to ensure the air quality in the surgical area and the smooth progress of the operation; by providing a cooling pipe, the skin surface can be cooled to prevent excessive temperature from burning the skin; therefore, when performing laser therapy on the skin surface, the 1470nm semiconductor laser therapy device of the present invention is used to greatly improve the effect of laser therapy and ensure the safety of the treatment process.

[0051] In one embodiment, the laser output module also includes: a direct laser fiber, a ring-type laser fiber and a scattered light biological probe, and the laser output interface is also used to connect to the optical fiber connection line of the direct laser fiber, the optical fiber connection line of the ring-type laser fiber and the optical fiber connection line of the scattered light biological probe respectively.

[0052] The ring-shaped laser fiber is used to output a 360-degree annular spot, radially and evenly focusing on the blood vessel wall, the energy is evenly distributed along the blood vessel wall, and the energy density used is lower. It greatly reduces the blood vessel perforation rate, there is no thermal damage and carbonization of the blood vessel wall, no complications such as bruises and edema, thereby eliminating intraoperative and postoperative pain. The front end is conical, the push type is better, and the ultra-slip guide wire and catheter are no longer used. The outer size of the optical fiber sleeve is marked to facilitate the doctor to control the retraction speed to achieve more accurate dose control. It solves the problem that conventional bare optical fibers are prone to perforation and carbonization when they directly contact the blood vessel wall, and the energy density is uncontrollable, resulting in incomplete vascular closure due to too low laser energy, and easy perforation to form hard scabs and scabs due to too high laser energy, and strong pain.

[0053] The existing 1470nm semiconductor laser therapeutic devices used in clinical medicine generally have weak laser control capabilities and a single output laser mode, and cannot control the output of direct, circular, scattered, and dot matrix multiple modes of therapeutic lasers. As a result, it is impossible to selectively output direct mode laser, 360-degree circular mode laser, dot matrix mode laser, and scattered mode laser through the same 1470nm semiconductor laser therapeutic device. The laser output module of this embodiment is provided with a direct laser fiber, a ring-type laser fiber and a scattering photobiotherapy probe in addition to a fractional laser handpiece. Therefore, a 1470nm semiconductor laser therapy device can be used to output a point-mode laser through a direct laser fiber for controllable tissue vaporization and ablation therapy, and can also output a 360-degree ring-mode laser through a ring-type laser fiber for safe intracavitary therapy. It can also output a point-mode laser through a fractional therapy handpiece for fine light scanning skin surface repair therapy, and can further output a scattering mode laser through a photobiotherapy probe for efficient wound, ulcer and wound surface photobiostimulation regulation therapy, thereby achieving multi-mode laser therapy required for clinical medicine through a 1470nm semiconductor laser therapy device.

[0054] like Figure 4 As shown, in one embodiment, it also includes: an automatic fiber pulling device for adjusting and positioning the optical fiber connection line of the 1470nm semiconductor laser therapy device, the automatic fiber pulling device includes: an optical fiber box 18, for accommodating the optical fiber connection line; a first hole and a second hole are opened on its side, wherein the first hole is used for one end of the optical fiber connection line to pass through so as to be connected to the laser output interface 20 of the 1470nm semiconductor laser therapy device, and the second hole is used for the other end of the optical fiber connection line to pass through so as to reach the lesion 21; an optical fiber disc 14, which is arranged inside the optical fiber box and is used to store the optical fiber connection line; a driving motor 15, which drives the rotating shaft connected to the optical fiber disc, and is used to control the rotation of the optical fiber disc so as to retract and release the optical fiber connection; a motor control device, connected to the driving motor, is used to control the start, stop, direction and speed of the driving motor.

[0055] In this embodiment, the working circuit of the motor control device includes a switch key and a speed regulating knob. The switch key 16 and the speed regulating knob 17 are both arranged on the outer surface of the optical fiber box 18 .

[0056] The rotating shaft of the driving motor can be connected to the rotating shaft of the optical fiber disk through a coupling, thereby driving the rotation of the optical fiber disk.

[0057] When using the automatic fiber optic pulling device of this embodiment, first control the rotation of the fiber optic reel by driving the motor to wind the optical fiber connecting line around the fiber optic reel. During laser treatment, adjust the speed knob to set the pulling speed, press the power button on the fiber optic box, and the motor device roller starts working, driving the fiber optic reel to complete the uniform speed fiber retraction work. In the middle, you can twist the speed knob according to the speed of retracting and releasing the optical fiber to make the fiber optic reel reach a suitable speed.

[0058] The automatic fiber pulling device of the present embodiment realizes the uniform withdrawal or release of the laser fiber by driving the cooperation of the driving motor and the fiber optic disc, thereby reducing the error of medical staff in manually pulling out the laser fiber, alleviating the surgical operation pressure of medical staff, and preventing the uneven and uncontrollable movement speed of the laser fiber; in addition, the automatic fiber pulling device of the present embodiment adopts a split structure, which is convenient and fast, and easy to carry when in use.

[0059] In one embodiment, the automatic optical fiber pulling device also includes a fixing device 19 arranged at the second hole for fixing the optical fiber connection line, and the fixing device includes: a pressing groove for the optical fiber connection line to pass through and a pressing plate for applying pressure to the pressing groove, when the first end of the pressing plate is pressed, the second end will be lifted, and when the second end is not pressed, the second end will be pressed on the pressing groove.

[0060] By setting a fixing device, the optical fiber connecting line at the outlet of the optical fiber box can be fixed to prevent the length of the optical fiber connecting line extending out of the optical fiber box from changing when the driving motor is not started, thereby ensuring the stability of the operation of the automatic optical fiber pulling device.

[0061] like Figure 5 As shown, in one embodiment, the control system module includes: a temperature control module for controlling the working temperature of the laser module, a main control board for issuing control instructions to the temperature control module and the laser module, an operation screen for human-computer interaction, and a power supply module for supplying power to the temperature control module, the main control board and the operation screen, and the main control board is respectively connected to the temperature control module, the laser module and the operation screen.

[0062] The operation screen can be loaded with laser operation program software and clinical function application software. The laser operation program software automatically identifies the laser operation status according to the set operation parameters through the central processor, and independently adjusts the laser operation parameters to maintain the efficient and stable operation of the laser. The clinical function application software is equipped with treatment plans and management menus. The treatment plans include surgical treatment, vascular treatment, gynecological treatment, photobiological treatment, fractional treatment, lipolysis treatment and other clinical disease treatment software modules. Clinicians can choose appropriate clinical disease treatment software according to the type of clinical disease, set different laser treatment parameters, and select different fiber optic instruments and tools for laser surgical disease treatment. Especially when selecting the vascular treatment software module for intracavitary laser ablation closure treatment of vascular diseases such as great saphenous varicose veins, small saphenous varicose veins, and branch varicose veins, not only can the laser power be set in the treatment software, but also the LEED (energy density J / cm) can be set, and the 360-degree ring-shaped light emission dedicated laser fiber for intravascular treatment with a size length scale marked on the fiber optic sleeve can be selected.

[0063] Linear energy density: The required linear energy density is set according to the patient's blood vessel depth, diameter, blood vessel wall thickness, etc. LEED: linear endovenous energy density, J / cm, refers to the average treatment energy per centimeter of blood vessel.

[0064] The doctor can set the treatment power P in the laser operating program software.

[0065] The relationship among LEED, power P, and withdrawal speed v is: v=P / LEED, and the unit of withdrawal speed v is cm / s.
