Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0031] The following is combined with Figures 1 to 5 , the laser therapy handpiece provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0032] See also Figure 1~Figure 5 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 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., so as to improve the patient's skin problems and enhance the skin quality.

[0033] In the embodiments of this application, please refer to 1. Figure 2 and Figure 3 The disclosed laser therapy handpiece includes a base shell 100, a lens assembly 200, a sleeve 300, a connector 400 and a detection assembly 500, wherein the base shell 100 is a basic component of the laser therapy handpiece, and can provide a mounting and protection basis for the lens assembly 200, the sleeve 300 and the connector 400. Specifically, the base shell 100 is provided with a light guide channel 110. Exemplarily, the light guide channel 110 penetrates the base shell 100 along the axial direction of the base shell 100, and the lens assembly 200 is movably arranged in the light guide channel 110. Exemplarily, the lens assembly 200 is movably arranged along the axial direction of the base shell 100, and 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.

[0034] In the embodiments of this application, see 2, Figure 3 and Figure 4 , the sleeve 300 is rotatably sleeved on the outer side of the base shell 100. Exemplarily, the sleeve 300 is coaxially sleeved on the outer side of the base shell 100. The base shell 100 is provided with a spiral guide groove 120 that penetrates the base shell 100. The spiral guide groove 120 spirally extends along the axial direction of the base shell 100. The inner end of the connecting piece 400 is connected to the lens assembly 200. The outer end of the connecting piece 400 passes through the spiral guide groove 120 and slides with the sleeve 300. In the embodiment of the present application, the connecting piece 400 and the sleeve 300 slide in the axial direction of the base shell 100. When the sleeve 300 is rotated, the connecting piece 400 rotates with the sleeve 300 and moves axially relative to the sleeve 300, and then drives the lens assembly 200 in the base shell 100 to move axially relative to the base shell 100, thereby realizing the focusing of the laser beam. Exemplarily, the laser therapy handpiece of the embodiment of the present application can realize focusing by manually rotating the sleeve 300.

[0035] In the embodiment of the present application, the change of the circumferential rotation position of the sleeve 300 determines the change of the focal length, and further determines the spot size used by the laser treatment handpiece. Therefore, the spot size used by the laser treatment handpiece can be determined by detecting the circumferential rotation position of the sleeve 300, thereby facilitating the recording of the spot size. For details, please refer to Figure 3 and Figure 4 The detection component 500 includes a circuit board 510 and a detection module 520 arranged on the circuit board 510. The circuit board 510 is arranged opposite to the sleeve 300 and adjacent to the sleeve 300. In order to control the radial size of the entire laser treatment handpiece, the circuit board 510 is preferably extended along the axial direction of the base shell 100. The sleeve 300 is provided with at least two detection marks 310 distributed along its circumference. When the sleeve 300 rotates, the detection module 520 identifies the detection marks 310 distributed circumferentially on the sleeve 300, so that the rotation position of the sleeve 300 in the circumferential direction can be detected and determined. The rotation position of the sleeve 300 determines the detection and recording of the spot size, thereby ensuring the safety and effectiveness of the treatment process.

[0036] See also Figure 3 and Figure 4, the detection module 520 includes at least two photoelectric sensors disposed on the circuit board 510, and the two or more photoelectric sensors are also distributed along the axial direction of the base shell 100, and the two or more photoelectric sensors are distributed at the same circumferential position of the entire laser therapy handpiece. In the embodiment of the present application, the detection mark 310 can be at least two detection windows opened on the sleeve 300, and the detection windows penetrate the side wall of the sleeve 300. The number of detection windows can be the same as the number of photoelectric sensors. The two or more detection windows are distributed along the axial direction of the sleeve 300 so as to correspond to the distribution position of the photoelectric sensors in the axial direction. At the same time, the detection windows are also distributed along the circumference of the sleeve 300, so that when the sleeve 300 rotates, the detection windows can rotate to the position corresponding to the photoelectric sensors. Exemplarily, three photoelectric sensors are distributed along the axial direction of the base shell 100, and the corresponding three detection windows are distributed along the axial direction of the sleeve 300 and are also staggered along the circumference of the sleeve 300. That is to say, one detection window corresponds to one photoelectric sensor. In this way, the three rotational positions of the sleeve 300 can be detected by the three photoelectric sensors.

[0037] In the above embodiment, one of the base shell 100 and the sleeve 300 is configured to reflect the light signal emitted by the photoelectric sensor, and the other is configured to absorb the light signal emitted by the photoelectric sensor. Exemplarily, the outer wall of the sleeve 300 can reflect the light signal emitted by the photoelectric sensor, and the outer wall of the base shell 100 can absorb the light signal emitted by the photoelectric sensor. Exemplarily, the outer wall of the base shell 100 is coated with a dark coating to absorb the light signal. When the sleeve 300 is adjusted to rotate so that the detection window is opposite to the photoelectric sensor, the detection signal of the photoelectric sensor changes. By detecting the working states of different photoelectric sensors, the rotation position of the sleeve 300 can be determined, thereby realizing the detection and recording of the current spot size of the laser treatment handpiece.

[0038] In some embodiments of the present application, the detection module 520 further includes at least two Hall sensors distributed along the axial direction of the base shell 100, and the detection mark 310 is at least two magnetic induction components provided on the sleeve 300. Similarly, the two or more magnetic induction components are distributed along the axial direction of the sleeve 300 so as to correspond to the distribution position of the Hall sensors in the axial direction. At the same time, the magnetic induction components are also distributed along the circumference of the sleeve 300. When the sleeve 300 rotates, the magnetic induction components can rotate to a position corresponding to the Hall sensor so as to be detected by the Hall sensor to determine the current rotation position of the sleeve 300. It should be noted that in the embodiments of the present application, the magnetic induction component should be a device that can be detected by a Hall sensor, for example, a magnet, or a device made of a magnetic material (such as iron, cobalt, nickel and alloys thereof).

[0039] As can be seen from the foregoing, the laser therapy handpiece of the embodiment of the present application can be focused manually. In an optional implementation, the outer side of the sleeve 300 is also provided with an anti-slip portion 320 extending along its circumference. The anti-slip portion 320 can be an anti-slip pattern distributed around the sleeve 300. The operator can contact and rotate the anti-slip portion 320 to adjust the focal length. The anti-slip portion 320 can make the operator's focusing operation more stable and reliable, thereby improving the fineness of the spot size adjustment.

[0040] In some embodiments of this application, see Figure 1 , Figure 2 and Figure 3 The laser treatment handpiece may further include a housing 600, which has a storage space and can provide an installation basis for the aforementioned base shell 100, lens assembly 200, sleeve 300 and detection assembly 500. Specifically, the housing 600 is arranged on the outside of the sleeve 300. In order to facilitate the rotation adjustment of the sleeve 300, an operation window 610 that penetrates the housing 600 is arranged on the housing 600. A part of the anti-slip part 320 is located in the operation window 610. The operator can realize the rotation adjustment of the sleeve 300 through the part of the anti-slip part 320 exposed in the operation window 610.

[0041] In a further technical solution, the sleeve 300 is further provided with a spot size mark 330 adjacent to the anti-slip portion 320. For example, the spot size mark 330 can be a combination of a digital mark and a scale mark, and the two are distributed along the circumference of the sleeve 300, and the spot size mark 330 also has a portion exposed in the operation window 610. The operator can intuitively judge the spot size used through the operation window 610. For example, it can be seen that the spot size is 5mm, 10mm, 15mm, etc. This can help the operator to more accurately realize the spot size of the laser beam used, and then accurately control the area on the skin where the laser beam is irradiated, thereby achieving precise treatment of the target lesion area.

[0042] In the examples of this application, see Figure 2 and Figure 5 The laser treatment handpiece further includes a damping module 700, which is disposed in the housing 600 and is configured to apply a damping force to the sleeve 300 to hinder the sleeve 300 from rotating. It should be noted that in the embodiment of the present application, the damping module 700 is not provided to limit the sleeve 300 from rotating, but after the sleeve 300 is rotated to adjust the spot size to a suitable size, a certain resistance force can be applied to the sleeve 300 to limit the sleeve 300 from rotating randomly, thereby ensuring the stability of the spot size, and when the operator needs to adjust the focus, the damping force applied by the damping module 700 can be overcome.

[0043] In an optional embodiment, the damping module 700 includes an elastic member (not shown) and an abutment member 720 connected to the elastic member, and the elastic member is configured to apply an elastic force to the abutment member 720 so that the abutment member 720 abuts against the sleeve 300. Exemplarily, the elastic member can be a spring, and the abutment member 720 can be a spherical structure. The abutment member 720 can abut against the end face of the sleeve 300 in the axial direction.

[0044] In a further technical solution, the sleeve 300 is provided with positioning recesses 340 distributed along its circumference, and the positioning recesses 340 may be concave arc surfaces, and the abutment member 720 of the spherical structure is positioned and matched with the positioning recesses 340 to increase the damping force of the damping module 700. When the operator adjusts the spot size, it is necessary to deliberately apply force to make the abutment member 720 disengage from the positioning recesses. Based on the positioning effect of the positioning recesses 340 on the abutment member 720, during laser treatment, the spot size is maintained at a specific size and will not be easily changed. Only when the operator rotates the sleeve 300 will the abutment member 720 be disengaged from the positioning recess 340, thereby ensuring the stability of the spot size.

[0045] In the embodiment of the present application, the focusing of the laser treatment handpiece is achieved by moving the lens assembly 200 in the base shell 100. The lens assembly 200 includes a base 210 and at least one lens unit 220. The base 210 is a 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 that runs through the axial direction thereof, and the lens unit 220 is disposed in the mounting cavity. For example, see Figure 2 , Figure 3 and Figure 4 The base 210 is a cylindrical structure, two lens units 220 are arranged in the installation cavity, and the two lens units 220 are distributed along the axial direction of the installation cavity, and the inner end of the connecting member 400 is connected to the base 210. When the connecting member 400 slides in the spiral guide groove 120, the base 210 moves axially relative to the base shell 100, thereby achieving focusing. It can be understood that the number of lens units 220 can be adaptively selected according to actual use requirements, and this application does not make specific restrictions on this.

[0046] It should be noted that, in this article, the term "comprises", "includes" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes 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 "including one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the method and device in the embodiment 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 reverse 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.
