Description

Technical Field

[0001] This disclosure relates to the field of medical device technology, and in particular to a laser therapy device and its control method. Background Technology

[0002] Needle-free injection technology (NFIT) uses the principle of pressure jet to administer medication subcutaneously. For example... Figure 1 and Figure 2 As shown, the pressure generated by the internal pressure device of the needle-free injector forces the liquid medication in the tube through micropores to form a liquid column, allowing the liquid medication to instantly penetrate the epidermis and reach the subcutaneous layer, where it is absorbed in a diffuse manner. The injection process of the optically driven needle-free injector is as follows... Figure 3 As shown, the laser is first focused through a lens onto a liquid-filled driving chamber to form plasma. The plasma absorbs energy and generates bubbles, which then grow and form a jet stream. Finally, the bubbles in the drug chamber of the needle-free injector disappear, and the liquid returns to stillness. Existing needle-free injectors have complex structures, high failure rates, and low production efficiency. Furthermore, as consumables, they are costly, placing a burden on patients. Additionally, existing needle-free injectors lack precise control over injection volume, have long driving force generation times, and exhibit uneven injection force, excessive splashing, and waste of injectable material. Moreover, the large single injection volume of existing needle-free injectors can lead to excessive cavitation damage to the skin surface, requiring a recovery period. The excessively concentrated local drug concentration also hinders skin absorption. The detachable needle-free injector head may also easily contaminate the driving fluid and drug solution inside, creating a risk of misuse. Reusing needle-free injectors can also lead to mixing of different types of drugs, and different patients using the same needle-free injector head, resulting in adverse drug reactions and cross-infection risks. Finally, laser treatment equipment includes a needle-free injector and a handpiece. Traditional laser treatment equipment uses a direct plug-in connection to connect the needle-free injector and handpiece, which is relatively complex in appearance. This makes traditional laser treatment equipment inconvenient to operate and affects the user experience. Summary of the Invention

[0058] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0059] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects.

[0060] Example 1

[0061] The laser therapy device in this embodiment employs an optically driven, needle-free injection method. The device primarily includes a needle-free injector and a handpiece. The handpiece's main function is to shape and focus the laser beam according to preset rules, altering the beam's spot size, convergence angle, and other optical parameters. This focuses the laser energy into the driving fluid of the needle-free injector, ionizing the fluid and generating plasma bubbles, thus creating driving pressure. The needle-free injector uses the driving force of the pulsed laser to create pressure within the medication chamber, forcing the medication out of the nozzle and into the skin tissue. This optically driven laser therapy device offers precise control over the injection volume, allowing for higher driving pressure, higher speed, and smaller diameter jets of medication. It features short injection time, high pressure, high efficiency, and controllable injection depth. Adjusting the laser pulse energy allows for precise control of the single injection volume, resulting in minimal skin surface damage, almost no pain, no need for anesthesia, less bleeding, a shorter recovery period, and frequent, small-volume drug injections that facilitate absorption by the skin. With single-jet times in the microsecond range, laser-induced technology offers even higher jet frequencies, eliminating the need for resetting or replacing the drive source and significantly improving treatment efficiency.

[0062] See Figure 4 The laser treatment device in this embodiment includes: a beam transmission module 62, a handpiece 01, and a needleless injector 02.

[0063] One end of the handpiece 01 is threadedly connected to the light outlet of the beam transmission module 62. The other end of the handpiece 01 is threadedly connected to the needleless injector 02.

[0064] The handpiece 01 is used to receive the first laser beam emitted by the beam transmission module 62, to shape and focus the first laser beam, and to change the optical parameters of the first laser beam.

[0065] The needleless injector 02 is used to receive a second laser beam emitted by the handpiece 01 to drive the liquid medication to be sprayed into the patient's skin tissue.

[0066] The optical path schematic diagram of this embodiment is as follows: Figure 5 As shown, the beam transmission module transmits the first laser beam emitted by the laser to the handpiece. The handpiece shapes and focuses the first laser beam through a first convex lens 0112, a concave lens 0114, and a second convex lens 0116, changing the spot size, convergence angle, and other optical parameters of the specific laser beam to form a second laser beam. The second laser beam is focused by the window lens 0203 of the needleless injector onto the driving liquid chamber 0205 inside the needleless injector, thereby exciting the driving liquid in the driving liquid chamber 0205 to ionize and generate plasma bubbles 51, thus generating driving pressure. The drug liquid flow 52 is ejected through the diaphragm 0206, the drug chamber 0207, and the nozzle 0209 of the needleless injector, realizing the needleless injection function.

[0067] It should be noted that the beam transmission system can be a light guide arm or an optical fiber.

[0068] This embodiment achieves a rotary connection by using a threaded connection between the beam transmission module, the handpiece, and the needleless injector, resulting in a simple structure and minimalist appearance for the laser therapy device, making it convenient for operators to use.

[0069] In one alternative implementation, the laser therapy device further includes a controller.

[0070] The controller is electrically connected to both the beam transmission module and the handpiece.

[0071] The controller is used to control the beam transmission module to emit the first laser beam. The controller is also used to identify the handpiece and the needleless injector.

[0072] In this embodiment, the controller is the control unit of the laser therapy device. Its main function is to control the laser therapy device to output a laser beam in the mode, frequency, pulse energy, pulse width, etc., required by the terminal, thereby focusing the pulsed laser onto the driving fluid in the needle-free injector, and monitoring the status of the entire laser therapy device, realizing functions such as laser energy calibration and abnormality indication. It can also assist in treatment and ensure safety.

[0073] In one alternative implementation, the controller and the handpiece are electrically connected via a cable. The handpiece has a mounting block. The mounting block secures the cable to the handpiece using mounting screws.

[0074] In this embodiment, the cable can be fixed to the handpiece by fixing blocks and fixing screws, thereby making the cable of the handpiece neater and the appearance of the laser treatment device more concise.

[0075] In one optional embodiment, the fixing block has a cavity inside. The hand tool includes a hand tool recognition plate. A first memory chip is provided on the hand tool recognition plate.

[0076] The hand recognition plate is located inside the cavity.

[0077] The memory chip is used to store at least one of the following handpiece information: model, serial number, treatment mode, and default setting parameters.

[0078] In this embodiment, the handpiece information is identified by the handpiece recognition plate, which facilitates the laser treatment device to realize the function of using a handpiece only on a single device, or to realize the adaptation function such as automatically calling up the treatment mode and recommended parameter settings of the corresponding connected handpiece based on the handpiece information, which greatly facilitates the user's use.

[0079] In one alternative embodiment, the handpiece further includes a pin plate. The needleless injector also includes a PCB substrate (printed circuit board). A second memory chip is disposed on the PCB substrate.

[0080] One end of the ejector plate is electrically connected to the handpiece recognition board via an ejector cable. The other end of the ejector plate is connected to the contacts on the PCB base plate via ejector pins.

[0081] The second memory chip stores at least one of the following needle-free injector information: model, anti-counterfeiting mark, usage status, effective usage time, and remaining number of shots. The ejector plate and PCB base plate are connected to transmit signals between the handpiece and the needle-free injector.

[0082] In this embodiment, communication between the first and second storage chips allows for the exchange of handpiece and needle-free injector information. This enables the laser treatment device to function as a single device for each handpiece and needle-free injector, allowing each device to be used on a single device. Alternatively, by recognizing handpiece and needle-free injector information, the device can automatically retrieve the corresponding treatment mode and recommended parameter settings for the connected handpiece and needle-free injector, greatly simplifying user operation.

[0083] In one alternative embodiment, the hand tool also includes a handle. The handle includes a plate groove.

[0084] The ejector plate is fixed in the plate groove by dispensing adhesive.

[0085] In this embodiment, the pin plate is secured by a slot, reducing the number of fixing screws. The components are fixed by interlocking, making the structure of the laser treatment device simpler and reducing the production and usage costs.

[0086] In one alternative embodiment, the handpiece further includes a lens barrel, a first convex lens, a concave lens, and a second convex lens.

[0087] The first convex lens is fixed to the lens barrel by a first retaining ring. The concave lens is fixed to the lens barrel by a second retaining ring. The second convex lens is fixed to the lens barrel by a third retaining ring. The lens barrel is screwed into the inside of the handle via a threaded connection.

[0088] In this embodiment, the handpiece uses optical lenses such as a first convex lens, a concave lens, and a second convex lens to shape and focus the first laser beam.

[0089] In one optional implementation, the laser treatment device further includes a drug feeder. The drug feeder is threadedly connected to a needle-free injector.

[0090] In this embodiment, the drug delivery device can be a standard sterile screw-type syringe or a screw-type infusion tubing delivery device.

[0091] In one alternative embodiment, the needle-free injector includes a threaded connector. The threaded connector includes a locating groove and a multi-start external thread. The handpiece includes a boss corresponding to the locating groove and a multi-start internal thread corresponding to the multi-start external thread.

[0092] By using complementary mating positioning grooves and bosses, screwing them into place until the multi-start external thread and multi-start internal thread are coupled, so that the needleless injector and hand tool are threadedly connected.

[0093] The number of starts in a multi-start thread can be 2, 3, 4, 5, 6, 7, 8, etc., without limitation. Multi-start internal threads correspond to multi-start external threads, and a portion of the internal thread teeth of a multi-start internal thread can be evenly distributed on the inside of the tool.

[0094] In one alternative embodiment, the needle-free injector includes a threaded connector and a housing. The threaded connector includes a first multi-start thread. The housing includes a first internal thread corresponding to the first multi-start thread.

[0095] The threaded joint and the housing are connected by coupling the first multi-start thread and the first internal thread.

[0096] It should be noted that a portion of the first multi-start thread can be evenly distributed on the threaded joint. The number of starts in the first multi-start thread can be 2, 3, 4, 5, 6, 7, 8, etc., and there is no limitation on this. The first internal thread corresponds to the first multi-start thread, and a portion of the internal thread tooth surface of the first internal thread can be evenly distributed on the inner side of the outer shell.

[0097] In one alternative embodiment, the needle-free injector includes a drive fluid chamber and a housing. The drive fluid chamber includes a second multi-start thread. The housing includes a second internal thread corresponding to the second multi-start thread.

[0098] The drive fluid chamber and the outer casing are threaded together by coupling the second multi-start thread and the second internal thread.

[0099] It should be noted that a portion of the second multi-start thread can be evenly distributed on the threaded joint. The number of starts in the second multi-start thread can be 2, 3, 4, 5, 6, 7, 8, etc., and there is no limitation on this. The second internal thread corresponds to the second multi-start thread, and a portion of the internal thread tooth surface of the second internal thread can be evenly distributed on the inner side of the outer shell.

[0100] In one alternative embodiment, the needle-free injector includes a drug chamber and a housing. The drug chamber includes a third multi-start thread. The housing includes a third internal thread corresponding to the third multi-start thread.

[0101] The liquid chamber and the outer shell are connected by coupling the third multi-start thread and the third internal thread.

[0102] It should be noted that a portion of the third multi-start thread can be evenly distributed on the threaded joint. The number of starts in the third multi-start thread can be 2, 3, 4, 5, 6, 7, 8, etc., without limitation. The third internal thread corresponds to the third multi-start thread, and a portion of the internal thread surface of the third internal thread can be evenly distributed on the inner side of the outer shell.

[0103] In this embodiment, the use of threaded connections instead of traditional fixing screws reduces the production cost and efficiency of the needle-free injector, as well as the cost of consumables for the needle-free injector, thereby reducing the treatment cost for patients.

[0104] In one optional embodiment, the laser therapy device further includes a laser. The laser and the beam transmission module are mechanically connected. The laser is also electrically connected to a controller, a handpiece, and a needle-free injector, respectively.

[0105] The controller is used to control the laser to send the laser beam to the beam transmission module.

[0106] In an optional implementation, the laser therapy device further includes a cooling module. The cooling module and the laser are connected via cooling water pipes. The cooling module is also electrically connected to a controller.

[0107] The controller is used to control the cooling module to cool and dissipate heat from the laser.

[0108] Due to limitations in current technology, the photoelectric conversion efficiency of lasers is extremely low, generally not exceeding 3%. Therefore, most of the energy in laser therapy equipment is dissipated as heat. This necessitates the addition of a cooling module with high cooling capacity to the laser device to cool and dissipate heat, thereby providing precise single-pulse laser energy and single-shot injection volume, ultimately achieving a stable needle-free injection effect.

[0109] The following is a specific example to illustrate the laser treatment device of this embodiment in detail.

[0110] like Figure 6 As shown, the laser therapy device in this example is used to treat targeted tissue. The laser therapy device includes a main unit 61, a beam transmission module 62, and application components 63. The main unit 61 includes an MCU (controller unit) 611, a laser 612, an electrical module 613, and a cooling module 614. The main unit's interface includes a touch control screen 615, a remote interlock switch 616, a foot switch 617, an emergency stop switch, a key switch 618, and a power cord 619. The application components 63 include a handpiece 01, a needle-free injector 02, and a drug delivery device 03.

[0111] Laser 612 is a laser generating device and a laser source. Its core component is a resonant cavity, which includes a focusing cavity, a total reflection mirror, a half reflection mirror, a laser crystal, a pump source, a aiming beam, and a power feedback system. The laser generating principle of laser 612 is based on the energy level transition of doped particles in the crystal from a high energy level to a low energy level, thereby releasing light quanta of a specific wavelength.

[0112] Electrical module 613 is a laser drive unit and the energy source for the laser generator. It outputs a high-voltage pulse voltage with a specific pulse width to power the pump source inside the laser 612.

[0113] The cooling module 614 cools the entire laser 612. Due to the limitations of existing technology, the photoelectric conversion efficiency of the laser 612 is extremely low, generally not exceeding 3%. Therefore, most of the energy in the entire device is dissipated as heat, which requires the cooling module 614 with a high cooling capacity to cool and dissipate heat from the laser 612.

[0114] The MCU611 is the controller for laser therapy equipment. Its main function is to control the laser therapy equipment to output laser light in the mode, frequency, pulse energy, and pulse width required by the terminal, thereby focusing the pulsed laser light into the driving fluid in the needle-free injector. It also monitors the status of the laser therapy equipment, enabling functions such as laser energy calibration and anomaly alerts, assisting in treatment and ensuring safety.

[0115] The host interaction interface, including the touch control screen 615, remote interlock switch 616, foot switch 617, emergency stop switch and key switch 618, and power cord 619, enables human-host interaction, thereby realizing functions such as laser parameter control, safety assurance, and energy supply.

[0116] The function of the beam transmission module 62 is to transmit the first laser beam generated by the laser 612 to the handpiece 01, and then focus it into the driving liquid chamber inside the needle-free injector to achieve needle-free injection. The beam transmission module 62 can be a light guide arm or an optical fiber.

[0117] Handpiece 01 can shape and focus the first laser beam, changing its spot size, convergence angle, and other optical parameters, thus focusing the laser energy into the driving fluid of the needle-free injector. This ionizes the driving fluid, generating plasma bubbles and thus producing driving pressure. Figure 7As shown, the threaded interface 010104 on the upper part of the handle 0101 of the handpiece is threadedly connected to the light output port of the optical transmission module. The multi-start threaded interface 010101 on the lower part of the handle 0101 is threadedly connected to the multi-start threaded interface 0202 of the needleless injector head. The function of the fixing block 0102 is to fix the cable to the handpiece 01. The fixing block 0102 has a cavity inside, in which the handpiece identification plate 0107 is placed, and an EEPROM storage chip (electrically erasable programmable read-only memory chip) is attached. The cable connector 0103 enables the connection between the handpiece 01 and the needleless injector and the host 61; enabling functions such as handpiece identification and needleless injector identification. The control cable 0104 is connected to the cable connector 0103. The cable end sleeve 0105 is made of soft rubber to prevent the cable from breaking due to pulling. The fixing screw 0106 cooperates with the cavity of the fixing block 0102 to fix the cable. The handpiece recognition board 0107 has an EEPROM storage chip. This chip stores handpiece information such as model and serial number, enabling each handpiece to be used on only a single device. Alternatively, by recognizing the handpiece model, the laser therapy device can automatically retrieve the corresponding treatment mode and recommended parameter settings for the connected handpiece, greatly simplifying user operation.

[0118] The lower end of the ejector cable 0108 is soldered to the arc-shaped ejector plate 0109, and the other end of the ejector cable 0108 is connected to the handpiece identification board 0107. When the needleless injector 02 and the handpiece 01 are mechanically connected via multi-threaded screws, the ejector pins on the arc-shaped ejector plate 0109 make contact with the contacts on the arc-shaped PCB base plate 0201, achieving conductivity and thus enabling signal transmission. Figure 8 This is a schematic diagram of signal transmission between the handpiece 01 and the needleless injector 02.

[0119] In addition, such as Figure 7 As shown, the arc-shaped ejector plate 0109 of the handpiece is fixed to the arc-shaped groove 010102 on the handle 0101 using an adhesive dispensing process. The semi-circular boss 010103 of the handpiece and the semi-circular notch of the threaded connector 0202 are mutually aligned and screwed into place. Inside the handle 0101 is a set of optical lenses to shape and focus the light beam. The first retaining ring 0111 fixes the first convex lens 0112 to the lens barrel 0113, the second retaining ring 0115 fixes the concave lens 0114 to the lens barrel 0113, and the third retaining ring 0117 fixes the second convex lens 0116 to the lens barrel 0113. The lens barrel 0113 is screwed into the handle 0101 via a threaded connection.
