Description

Technical Field

[0001] The present invention relates to the technical field of laser therapeutic apparatus, in particular to a laser therapeutic apparatus which is convenient for switching output laser. Background Art

[0002] Laser therapy is a highly integrated medical device that integrates multidisciplinary knowledge such as laser technology, medicine, microelectronics and new material science. Its core principle is to use the laser beam generated by the laser to focus through a precise optical system such as a reflector, so that the laser beam can be highly concentrated to form a beam with high energy density. This high-energy beam can accurately act on human tissues and stones, and through the photothermal effect, it can achieve the treatment of diseases such as prostate, tumors and stones.

[0003] Laser therapy devices can be divided into many types according to the laser wavelength, and different types of lasers have different performance and effects. Holmium laser therapy devices and thulium laser therapy devices are the most common lasers for the treatment of urinary diseases. Among them, the wavelength of holmium laser is about 2100 nanometers, which is just within the absorption range of water. Therefore, its main energy is concentrated on the surface, and it has excellent urinary stone crushing ability. In addition, the pulse time of holmium laser is much shorter than the thermal conduction time of tissue, so it has minimal thermal damage to surrounding tissues and a small tissue penetration depth. It is the gold standard for the treatment of urinary stones. The wavelength of thulium laser is about 1940 nanometers, with extremely high monochromaticity and energy density. It can accurately act on the target tissue for cutting, and it also has a good hemostatic effect. Specifically, during the operation, the user needs to decide which laser therapy device to use according to the needs of the operation.

[0004] In the prior art, both holmium laser therapy machines and thulium laser therapy machines are separate treatment instruments, and both require external optical fibers for use. Therefore, in actual application, if the staff needs to change the laser type, they have to change the laser therapy machine, which is quite troublesome. If the holmium laser generator and the thulium laser generator are set inside a treatment machine, and the two share an output optical fiber, then how to quickly and accurately switch the output optical fiber between the holmium laser generator and the thulium laser generator is also a problem that technicians in this field need to solve urgently.

[0037] The present embodiment also includes a laser generating mechanism 600, which includes a holmium laser generator 601, a thulium laser generator 602, an optical fiber adapter 603, and a housing 604, wherein the holmium laser generator 601 and the thulium laser generator 602 are respectively arranged on the upper and lower sides of the housing 604, the optical fiber adapter 603 is connected to the optical fiber output connector 102 through an optical fiber, and the optical fiber adapter 603 is respectively used to connect to the holmium laser generator 601 and the thulium laser generator 602. The user connects to the optical fiber output connector 102 through the output optical fiber, wherein when the optical fiber adapter 603 is connected to the holmium laser generator 601, the output optical fiber can emit holmium laser, and when the optical fiber adapter 603 is connected to the thulium laser generator 602, the output optical fiber can emit thulium laser.

[0038] Among them, the power supply mechanism 300 includes a first power supply 301 and a second power supply 302, the first power supply 301 is electrically connected to the holmium laser generator 601, and the second power supply 302 is electrically connected to the thulium laser generator 602; the first power supply 301 and the second power supply 302 are both arranged on the inner side of the bottom of the laser therapy machine body 100.

[0039] The present embodiment also includes a laser switching mechanism 700, which includes a movable vertical plate 701, which is slidably connected to the interior of a housing 604, and a displacement portion 702 which can be lifted and lowered vertically is slidably connected to the movable vertical plate 701, and an optical fiber adapter 603 passes through the displacement portion 702 and is fixedly connected thereto; when the displacement portion 702 moves to the top of the movable vertical plate 701, the optical fiber adapter 603 is used to connect to the holmium laser generator 601, and when the displacement portion 702 moves to the bottom of the movable vertical plate 701, the optical fiber adapter 603 is used to connect to the thulium laser generator 602.

[0040] The present embodiment also includes an installation partition 800, which is fixedly arranged inside the laser therapy machine body 100, and a heat dissipation channel 801 is formed between the installation partition 800 and the rear side wall of the laser therapy machine body 100. The casing 604 is fixedly arranged on the installation partition 800, and an air inlet 802 communicating with the interior of the casing 604 is also opened on the installation partition 800; the heat dissipation mechanism 500 includes a heat dissipation fan 501, and the air outlet end of the heat dissipation fan 501 passes through the installation partition 800 and extends into the inner side of the heat dissipation channel 801; therefore, when the heat dissipation fan 501 pumps air into the heat dissipation channel 801, the air can be blown into the casing 604 through the air inlet 802, which is used to cool the laser generating mechanism 600.

[0041] In addition, the heat dissipation mechanism 500 also includes a water cooling component 502, which is connected to the water cooling channel inside the holmium laser generator 601; since the power and heating efficiency of the holmium laser generator 601 are higher than the power and heating efficiency of the thulium laser generator 602, in order to improve the heat dissipation efficiency of the holmium laser generator 601, a water cooling component 502 is added to cool the holmium laser generator 601 separately.

[0042] In some embodiments of the present application, an air inlet cover 803 is provided on the inner side of the housing 604 and at the position of the air inlet 802. The air inlet cover 803 is fixedly connected to the mounting baffle 800. The air inlet cover 803 is located between the holmium laser generator 601 and the thulium laser generator 602, and the top wall and the bottom wall of the air inlet cover 803 are evenly provided with first through holes 804. Therefore, the air entering the air inlet cover 803 can act on the holmium laser generator 601 and the thulium laser generator 602 through the first through holes 804 on the top wall and the bottom wall.

[0043] In order to realize the switching of the optical fiber adapter 603 between the holmium laser generator 601 and the thulium laser generator 602, the laser switching mechanism 700 is described in detail below:

[0044] The top and bottom of the movable vertical plate 701 are both provided with a slide 703, and the two slides 703 are respectively connected to the top wall and the bottom wall of the housing 604 in a sliding manner, and the slide 703 at the top of the movable vertical plate 701 is provided with an upper electromagnet 704, and the slide 703 at the bottom of the movable vertical plate 701 is provided with a lower electromagnet 705, and the displacement portion 702 is made of a metal material that can be attracted by the electromagnet. Specifically, the displacement portion 702 can be made of stainless steel. In addition, it should be noted that the output ends of the holmium laser generator 601 and the thulium laser generator 602 are both facing the movable vertical plate 701, and the sliding direction of the movable vertical plate 701 is consistent with the axial direction of the output ends of the holmium laser generator 601 and the thulium laser generator 602.

[0045] When the upper electromagnet 704 is energized and the lower electromagnet 705 is de-energized, the displacement portion 702 is attracted by the upper electromagnet 704 and is located at the top of the movable vertical plate 701, and the optical fiber adapter 603 is aligned with the output connector of the holmium laser generator 601; when the lower electromagnet 705 is energized and the upper electromagnet 704 is de-energized, the displacement portion 702 is attracted by the lower electromagnet 705 and is located at the bottom of the movable vertical plate 701, and the optical fiber adapter 603 is aligned with the output connector of the thulium laser generator 602.

[0046] On the other hand, two air ducts 805 are provided on the side of the air inlet cover 803 facing the movable vertical plate 701, and a guide hole 706 for inserting the air duct 805 is penetrated on the movable vertical plate 701. The movable vertical plate 701 is an internal hollow structure, and an air hole 707 communicating with the interior of the movable vertical plate 701 is penetrated on the inner surface of the guide hole 706, and an air outlet hole 806 matched with the air hole 707 is provided on the side wall of the air duct 805; when the optical fiber adapter 603 is connected to the holmium laser generator 601 or the thulium laser generator 602, the air outlet hole 806 is aligned with the air hole 707, that is, at this time, the air inside the air inlet cover 803 can enter the interior of the movable vertical plate 701 through the air duct 805, the air outlet hole 806 and the air hole 707.

[0047] The ends of the two air guide tubes 805 are connected to a baffle 807, and the baffle 807 is provided with two self-locking button switches 808 on one side facing the movable vertical plate 701. The two self-locking button switches 808 are respectively connected in series with the upper electromagnet 704 and the lower electromagnet 705, and one of the two self-locking button switches 808 is in a closed state, and the other is in an open state. It is worth mentioning that the present embodiment also includes a DC power supply (not shown in the figure), which is connected to the upper electromagnet 704 and the lower electromagnet 705 through a wire, and the two self-locking button switches 808 correspond to the upper electromagnet 704 and the lower electromagnet 705 one by one, respectively, for controlling the power on and off of the corresponding electromagnet. In addition, since one of the two self-locking button switches 808 is closed and the other is disconnected, only one of the upper electromagnet 704 and the lower electromagnet 705 is always in a powered state.

[0048] The embodiment of the present application further includes a driving assembly 900, which is located inside the housing 604. The driving assembly 900 is used to drive the movable vertical plate 701 to move closer to or farther from the holmium laser generator 601 and the thulium laser generator 602. Specifically, the driving assembly 900 uses an electric push rod, which is fixedly arranged inside the air inlet cover 803. The movable end of the electric push rod penetrates the side wall of the air inlet cover 803 and extends to the outside of the air inlet cover 803. A mounting bracket 708 is provided on the side of the movable vertical plate 701 facing the air inlet cover 803, and the movable end of the electric push rod is fixedly connected to the mounting bracket 708. Therefore, the movable vertical plate 701 can be directly controlled to slide forward and backward by the electric push rod, so that the movable vertical plate 701 moves closer to or farther from the holmium laser generator 601 and the thulium laser generator 602.

[0049] In the specific application process of this embodiment, in the initial state, the optical fiber adapter 603 is connected to one of the holmium laser generator 601 and the thulium laser generator 602. Now, the connection between the optical fiber adapter 603 and the holmium laser generator 601 is taken as an example. When the user needs to emit thulium laser, he only needs to start the electric push rod through the external button to extend and retract the movable end of the electric push rod. In this process, the movable vertical plate 701 first carries the optical fiber adapter 603 away from the air inlet cover 803, and then the optical fiber adapter 603 and the holmium laser generator 601 are disconnected until the movable vertical plate 701 collides with two self-locking button switches 808, then the upper electromagnet 704 is powered off, and the lower electromagnet 705 is powered on. Under the action of magnetic attraction, the displacement part 702 moves downward until the optical fiber adapter 603 is aligned with the output interface of the thulium laser generator 602, and then under the thrust of the movable vertical plate 701, the optical fiber adapter 603 is successfully connected to the thulium laser generator 602.

[0050] In some embodiments of the present application, the displacement portion 702 is an internal hollow structure, a plurality of blowing holes 709 are provided on one side of the displacement portion 702 facing the air inlet cover 803, a strip opening distributed vertically is provided in the middle position of the movable vertical plate 701, the displacement portion 702 is slidably connected in the strip opening, a first ventilation hole 710 and a second ventilation hole 711 are respectively provided on the upper and lower sides of the surface of the movable vertical plate 701, a first ventilation pipe 712 is provided on the inner side of the movable vertical plate 701 and at the position of the first ventilation hole 710, and the movable vertical plate 701 is provided with a first ventilation pipe 712. A second ventilation pipe 713 is provided on the inner side and at the position of the second ventilation hole 711, and solenoid valves are provided on the first ventilation pipe 712 and the second ventilation pipe 713, wherein the solenoid valve on the first ventilation pipe 712 and the upper electromagnet 704 are arranged in series, and the solenoid valve on the second ventilation pipe 713 and the lower electromagnet 705 are arranged in series; that is, when the upper electromagnet 704 is energized, the solenoid valve on the first ventilation pipe 712 is also opened, and when the lower electromagnet 705 is energized, the solenoid valve on the second ventilation pipe 713 is also opened.

[0051] Furthermore, a third air hole 714 is provided on the displacement portion 702; when the optical fiber adapter 603 is connected to the holmium laser generator 601, the third air hole 714 is aligned with the first air hole 710; when the optical fiber adapter 603 is connected to the thulium laser generator 602, the third air hole 714 is aligned with the second air hole 711. Therefore, when the optical fiber adapter 603 is connected to the holmium laser generator 601, air can enter the displacement part 702 through the first air hole 710 and the third air hole 714, and then be blown out from the blowing hole 709 on the front of the displacement part 702, so that the air is blown toward the holmium laser generator 601; when the optical fiber adapter 603 is connected to the thulium laser generator 602, air can enter the displacement part 702 through the second air hole 711 and the third air hole 714, and then be blown toward the thulium laser generator 602 from the blowing hole 709, so that the gas blown out from the blowing hole 709 can always act on the laser generator in the working state.

[0052] In order to allow the air in the air inlet cover 803 to be concentrated and blown toward the laser generator in working state, the structure of the air inlet cover 803 is described in detail below:

[0053] The top and bottom surfaces of the air inlet cover 803 are both movably provided with a baffle plate 813 and fixedly provided with a positioning block 809. The baffle plate 813 is provided with a plurality of second through holes 810, which correspond one to one with the first through holes 804. The positioning block 809 is fixedly provided with a guide rod 811, which is slidably matched with the corresponding baffle plate 813, and a return spring 812 is sleeved on the outer side of the guide rod 811, and the two ends of the return spring 812 are respectively fixedly connected with the baffle plate 813 and the positioning block 809; when the return spring 812 is in a natural state, the second through holes 810 and the first through holes 804 are staggered. Since the guide rod 811 and the baffle plate 813 are slidably matched, the baffle plate 813 can slide along the length direction of the guide rod 811.

[0054] Furthermore, magnetic blocks 715 are provided at the top and bottom of the displacement part 702, and the baffle plate 813 is made of a metal material that can be attracted by the magnetic blocks 715, such as iron. When the optical fiber adapter 603 is connected to the thulium laser generator 602, the magnetic block 715 located at the top of the displacement part 702 and the baffle plate 813 located below the air inlet cover 803 are aligned, and under the attraction of the magnetic block 715, the second through hole 810 on the baffle plate 813 and the corresponding first through hole 804 are aligned; when the optical fiber adapter 603 is connected to the holmium laser generator 601, the magnetic block 715 located at the bottom of the displacement part 702 and the baffle plate 813 located above the air inlet cover 803 are aligned, and under the attraction of the magnetic block 715, the second through hole 810 on the baffle plate 813 and the corresponding first through hole 804 are aligned.

[0055] That is, when the holmium laser generator 601 is working, the air in the air inlet cover 803 can be discharged through the first through hole 804 located at the top thereof, thereby directly acting on the holmium laser generator; when the thulium laser generator 602 is working, the air in the air inlet cover 803 can be discharged through the first through hole 804 located at the bottom thereof, thereby directly acting on the thulium laser generator 602, thereby achieving precise heat dissipation.

[0056] It should be noted that the top and bottom surfaces of the housing 604 are provided with mounting seats, and the holmium laser generator 601 and the thulium laser generator 602 are respectively installed on the two mounting seats; in addition, the top and bottom walls of the housing 604 are provided with exhaust holes 605 located inside the mounting seats for the gas inside the housing 604 to escape.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
