Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.
[0039] The present application discloses a laser treatment handpiece. Figures 1 to 7 , the laser therapy handpiece provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.
[0040] See Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application discloses a laser treatment handpiece, which is used for cosmetic laser treatment. The laser treatment handpiece can introduce laser light of a specific wavelength into the subcutaneous tissue of the human body and perform laser irradiation on the target to be treated in the human skin (such as pigment particles, acne, etc.).
[0041] In the examples of this application, see Figure 2 and Figure 7 The disclosed laser therapy handpiece includes a housing 100, a lens assembly 200, a sleeve 300, a connector 400, and a drive module 500, wherein the housing 100 is the basic component of the laser therapy handpiece, and can provide a foundation for installation and protection of the lens assembly 200, the sleeve 300, the connector 400, and the drive module 500. Specifically, the housing 100 is provided with a light guide channel 110. Exemplarily, the light guide channel 110 penetrates the housing 100 along the axial direction of the housing 100. The lens assembly 200 is movably disposed in the light guide channel 110. Exemplarily, the lens assembly 200 is movably disposed along the axial direction of the housing 100. The laser beam is incident from the proximal opening of the light guide channel 110 and is emitted from the distal opening of the light guide channel 110 after passing through the lens assembly 200.
[0042] In the examples of this application, see Figure 4 、 Figure 5 and Figure 7 The sleeve 300 is rotatably sleeved on the outer side of the shell 100. For example, the sleeve 300 is coaxially sleeved on the outer side of the shell 100. The shell 100 is provided with a spiral guide groove 120 that penetrates the shell 100. The spiral guide groove 120 spirally extends along the axial direction of the shell 100. One end of the connecting member 400 is connected to the lens assembly 200, and the other end of the connecting member 400 passes through the spiral guide groove 120 and slides with the sleeve 300. In this embodiment of the present application, the connecting member 400 and the sleeve 300 slide together in the axial direction of the shell 100. When the sleeve 300 is rotated, the connecting member 400 rotates with the sleeve 300 and moves axially relative to the sleeve 300, thereby driving the lens assembly 200 in the shell 100 to move axially relative to the shell 100, thereby realizing focusing of the laser beam.
[0043] In an embodiment of the present application, the driving module 500 is disposed outside the shell 100, and the driving module 500 is connected to the sleeve 300. The driving module 500 is configured to drive the sleeve 300 to rotate, thereby causing the lens assembly 200 to move axially along the light guide channel 110. Exemplarily, the driving module 500 can be a motor and can be connected to the sleeve 300 through a gear transmission mechanism to drive the sleeve 300 to rotate.
[0044] Based on the above technical solution, the laser therapy handpiece of the embodiment of the present application drives the sleeve 300 to rotate through the driving module 500, so that the sleeve 300 drives the lens assembly 200 to move in the light guide channel 110 through the connecting member 400, and based on the sliding fit of the connecting member 400 in the spiral guide groove 120, within the extended area of the spiral guide groove 120, the position of the lens assembly 200 relative to the shell 100 can be steplessly adjusted. While realizing the electric focusing of the laser therapy handpiece, the adjustment of the spot size has the characteristics of fast response speed and high adjustment accuracy, thereby ensuring the laser therapy effect.
[0045] In the embodiment of the present application, the focusing of the laser treatment handpiece is achieved by moving the lens assembly 200 within the housing 100. The lens assembly 200 includes a base 210 and at least one lens unit 220. The base 210 is the basic component of the lens assembly 200 and can provide a mounting base for the lens unit 220. Specifically, the base 210 has a mounting cavity 211 extending through the base 210 along its axial direction, and the lens unit 220 is disposed in the mounting cavity 211. For example, see Figure 1The base 210 is a cylindrical structure, and two lens units 220 are disposed within the mounting cavity 211. The two lens units 220 are distributed axially along the mounting cavity 211. The inner end of the connector 400 is connected to the base 210. When the connector 400 slides within the spiral guide groove 120, the base 210 moves axially relative to the housing 100, thereby achieving focusing. It is understood that the number of lens units 220 can be adaptively selected based on actual usage requirements, and this application does not impose specific limitations on this.
[0046] For further technical solutions, see Figure 2 、 Figure 3 、 Figure 6 and Figure 7 The inner wall of the sleeve 300 is provided with a guide groove 310 extending along its axial direction. The guide groove 310 is recessed in the inner wall of the sleeve 300. The inner end of the connector 400 is threadedly engaged with the base 210, and the outer end of the connector 400 is slidably engaged in the guide groove 310. Because the base 210 and the sleeve 300 are respectively provided inside and outside the housing 100, the inner end of the connector 400 is threadedly engaged with the base 210, and the outer end of the connector 400 is slidably engaged with the guide groove 310, so that the connector 400 is a component independent of the base 210 and the sleeve 300, which can improve the convenience of assembly of the housing 100, the base 210 and the sleeve 300.
[0047] In some embodiments of this application, please continue to refer to Figure 2 and Figure 6 The driving module 500 includes a motor 510 and a gear connected to the motor 510. The motor 510 is arranged on the outside of the shell 100 and is fixed relative to the shell 100. A ring gear 320 is provided on the outer wall of the sleeve 300. The gear 520 is engaged with the ring gear 320. When the motor 510 rotates, it can drive the sleeve 300 to rotate, and then the lens assembly 200 moves in the shell 100. The use of a gear transmission mechanism has the characteristics of simple structure and high transmission stability, which is conducive to the size control of the laser treatment handpiece.
[0048] For further technical solutions, see Figure 2 and Figure 3 The sleeve 300 has a first protrusion 330 extending radially inward. For example, the first protrusion 330 can be arranged at the proximal end of the sleeve 300, and the shell 100 has a second protrusion 130 extending radially outward. The second protrusion 130 is arranged at the proximal end of the shell 100. In this way, after the sleeve 300 is sleeved on the shell 100, the first protrusion 330 and the second protrusion 130 are limited and matched along the axial direction of the shell 100 to prevent the sleeve 300 from jumping along the axial direction of the shell 100 toward the distal end of the shell 100, thereby ensuring the stability of the engagement between the gear 520 and the ring gear 320, and thereby ensuring the stability of the drive module 500 driving the sleeve 300 to rotate.
[0049] In the examples of this application, see Figure 2 and Figure 3 The laser therapy handpiece also includes a mounting seat 700, which is sleeved on the outside of the shell 100. The mounting seat 700 is distributed on the proximal side of the sleeve 300 and can limit the sleeve 300, so that the position of the sleeve 300 on the shell 100 is relatively determined, so that the ring gear 320 and the gear 520 are stably engaged.
[0050] In some embodiments of the present application, the laser therapy handpiece may further include a damping module 600. The mounting base 700 can provide a mounting base for the damping module 600. That is, the damping module 600 is disposed on the mounting base 700. The damping module 600 is configured to apply a damping force to the sleeve 300 to hinder the rotation of the sleeve 300. It should be noted that in the embodiments of the present application, the provision of the damping module 600 does not limit the driving module 500 to drive the sleeve 300 to rotate. Instead, after the driving module 500 stops driving, it can apply a certain resistance force to the sleeve 300 to limit the free rotation of the sleeve 300, thereby ensuring the stability of the spot size. When the driving module 500 drives the sleeve 300 to rotate, it can overcome the damping force applied by the damping module 600.
[0051] In an optional implementation, please continue to refer to Figure 3 The damping module 600 includes an elastic member 610 and an abutting member 620 connected to the elastic member 610. The elastic member 610 is disposed in the mounting seat 700. Under the elastic force of the elastic member 610, the abutting member 620 abuts against the sleeve 300, making it difficult for the sleeve 300 to rotate arbitrarily. For example, the elastic member 610 can be a spring, and the abutting member 620 can be a spherical structure. The spherical abutting member 620 has a smaller abutting contact area with the sleeve 300, so that the damping force applied is more appropriate, which can prevent the driving module 500 from generating a large frictional resistance when driving the sleeve 300 to rotate. It should be noted that in the embodiment of the present application, the abutting member 620 can selectively abut against the side wall of the sleeve 300 or the end face of the sleeve 300. This is not specifically limited in the present application.
[0052] In a further technical solution, the damping module 600 also includes a damping adjustment member 630, and a mounting hole is provided on the mounting seat 700, which passes through the mounting seat 700. For example, the mounting hole can pass through the mounting seat 700 along the axial direction of the mounting seat 700, and the damping adjustment member 630 is threadedly engaged in the mounting hole. One end of the elastic member 610 abuts against the damping adjustment member 630, and the other end of the elastic member 610 is connected to the abutment 620. By rotating the damping adjustment member 630, the depth of the damping adjustment member 630 engaged in the mounting hole can be adjusted, and then the elastic force applied by the elastic member 610 to the abutment 620 can be adjusted to achieve the adjustment of the damping force applied to the damping module 600.
[0053] In an embodiment of the present application, the abutment member 620 preferably abuts against the proximal end face of the sleeve 300. The proximal end face of the sleeve 300 is a plane. Compared with the manner in which the abutment member 620 abuts against the side wall of the sleeve 300, it has the characteristic of stable abutment, thereby ensuring that the damping module 600 applies stable damping to the sleeve 300.
[0054] In an embodiment of the present application, the driving module 500 can be installed on the mounting base 700, and the driving module 500 is arranged on the mounting base 700. In a preferred embodiment, a protective cover 710 is provided on the mounting base 700, and the driving module 500 is arranged in the protective cover 710, which can prevent the operator from accidentally touching the driving module 500.
[0055] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising 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, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved. For example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.
[0056] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
