[0027] The embodiment provides a laser single / dual-channel coupling output device, which comprises Figure 1 and Figure 2As shown, the laser single-double channel coupling output device includes a housing 100, a driving assembly 200, and a beam splitter 400. The housing 100 is provided with an incident port 110, a first exit port 120, and a second exit port 130. Incident light 10 incident from the incident port 110 can reach the first exit port 120 along a first light path 20. The driving assembly 200 is arranged in the housing 100 and is drivingly connected to the beam splitter 400. The driving assembly 200 is configured to drive the beam splitter 400 to a light splitting position that blocks the first light path 20 or an avoiding position that avoids the first light path 20. When the beam splitter 400 is located at the light splitting position, the incident light 10 is split into a first light 11 and a second light 12.

[0029] In the laser single-double channel coupling output device provided by the embodiment, the housing 100 serves as a mounting base to bear and mount the driving assembly 200, the beam splitter 400, and other required optical elements, so as to improve the arrangement convenience and stability of the components and ensure the stable operation of the output device. In addition, the housing 100 serves as a protective shell to isolate and protect the driving assembly 200, the beam splitter 400, and the like, so as to ensure the normal use of the output device. Furthermore, the driving assembly 200 can drive the beam splitter 400 to move to change the splitting state of the incident light 10, so that the output device enters a single-channel mode to make the incident light 10 emit out of the first exit port 120, or enters a double-channel mode to make the first light 11 and the second light 12 emit out of the first exit port 120 and the second exit port 130, respectively. Accordingly, the diversity of the laser output mode of the output device is improved, and the functionality and applicability of the output device are improved.

[0030] When the laser single-double channel coupling output device is applied to the laser treatment device, the following specific uses are provided.

[0031] When the laser treatment device only needs a single treatment handpiece to perform a treatment operation, for example, when the laser treatment device is used for a single treatment operation, the laser single-double channel coupling output device is in the single-channel mode. Figure 1As shown, the laser single / dual channel coupling output device is adjusted into the single channel mode, the driving assembly 200 drives the beam splitter 400 to move to the avoiding position, the laser is started to operate at the preset power, the laser emitted by the laser is incident into the shell 100 through the incident port 110 to become the incident light 10, the incident light 10 is in a straight line or reaches the first exit port 120 along the first light path 20 under the action of other optical elements, then the incident light 10 is emitted through the first exit port 120 to become the first exit light 11b, and the first exit light 11b can be emitted through the corresponding treatment hand tool and used for treatment.

[0032] When the laser treatment equipment needs two treatment hand tools to perform the treatment operation at the same time, for example, Figure 2 As shown, the laser single / dual channel coupling output device is adjusted into the dual channel mode, the driving assembly 200 drives the beam splitter 400 to move to the splitting position, the laser is started to operate at the preset power, the laser emitted by the laser is incident into the shell 100 through the incident port 110 to become the incident light 10, the incident light 10 is split into the first light 11 and the second light 12 by the beam splitter 400 when reaching the beam splitter 400 along the first light path 20, wherein the first light 11 continues to propagate along the first light path 20 to the first exit port 120, and is emitted through the first exit port 120 to become the first exit light 11b, and the first exit light 11b can be emitted through the corresponding treatment hand tool for treatment; at the same time, the second light 12 propagates along the second light path 30 to the second exit port 130, and is emitted through the second exit port 130 to become the second exit light 12b, and the second exit light 12b can be emitted through the corresponding another treatment hand tool for treatment.

[0033] When the laser single / dual channel coupling output device provided in the embodiment is applied to the laser treatment equipment, the single channel mode or the dual channel mode can be adjusted according to the needs, and the laser treatment equipment can perform the treatment mode of a single treatment hand tool or the treatment mode of two treatment hand tools, thereby improving the diversity of the treatment mode of the laser treatment equipment, and improving the use functionality, applicability and working efficiency of the laser treatment equipment.

[0034] Specifically, the laser single / dual channel coupling output device can satisfy the dual channel simultaneous output of single-wavelength laser, and can also satisfy the dual channel simultaneous output of dual-wavelength laser.

[0035] In the embodiment, the first light path 20 is provided with the first transmission mirror 520 with the transmittance greater than 99% and less than 100%, and the first transmission mirror 520 is located between the splitting position and the first exit port 120; the shell 100 is provided with the first detection assembly 530, and the first detection assembly 530 is configured to receive the first detection light 11a reflected by the first transmission mirror 520. In the single channel mode, as shown in Figure 1As shown, when the incident light 10 reaches the first transmitting lens 520 along the first light path 20, most of the light beams of the incident light 10 are transmitted through the first transmitting lens 520 and continue to propagate along the first light path 20 to the first exit port 120, and less than 1% of the light beams of the incident light 10 are reflected by the first transmitting lens 520 to become the first detection light 11a, which propagates to the first detection assembly 530. The first detection assembly 530 receives the first detection light 11a and detects the power of the incident light 10, the first split light 11, etc. according to the first detection light 11a, thereby ensuring the power accuracy of the exit light emitted through the first exit port 120, and accordingly ensuring the treatment accuracy of the laser treatment device in the single handpiece treatment mode.

[0036] Similarly, in the dual-channel mode, as shown in Figure 2 As shown, when the first split light 11 reaches the first transmitting lens 520 along the first light path 20, the first detection light 11a formed by the first transmitting lens 520 propagates to the first detection assembly 530 and is detected to ensure the power accuracy of the exit light emitted through the first exit port 120, and accordingly ensure the treatment accuracy of the laser treatment device in the dual handpiece treatment mode.

[0037] Similarly, in the embodiment, as shown in Figure 1 and Figure 2 As shown, the second light path 30 is provided with a second transmitting lens 630 with a transmittance greater than 99% and less than 100%, and the housing 100 is provided with a second detection assembly 640, which is configured to receive the second detection light 12a reflected by the second transmitting lens 630. In the dual-channel mode, when the second split light 12 reaches the second transmitting lens 630 along the second light path 30, most of the light beams of the second split light 12 are transmitted through the second transmitting lens 630 and continue to propagate along the second light path 30 to the second exit port 130, and less than 1% of the light beams of the second split light 12 are reflected by the second transmitting lens 630 to become the second detection light 12a, which propagates to the second detection assembly 640. The second detection assembly 640 receives the second detection light 12a and detects the power of the incident light 10, the second split light 12, etc. according to the second detection light 12a, thereby ensuring the power accuracy of the exit light emitted through the second exit port 130, and accordingly further improving the treatment accuracy of the laser treatment device in the dual handpiece treatment mode.

[0038] In the embodiment, as shown in Figures 1-3As shown, the housing 100 is provided with a linear guide rail 210 intersecting the first light path 20, the driving assembly 200 includes a linear driving member 220 provided on the housing 100 and a mounting frame 230 drivingly connected to the linear driving member 220, the mounting frame 230 is slidingly connected to the linear guide rail 210, and the beam splitter 400 is provided on the mounting frame 230. In use, the linear driving member 220 can drive the mounting frame 230 to drive the beam splitter 400 to move along the linear guide rail 210 towards the first light path 20, so that the beam splitter 400 reaches the light splitting position shielding the first light path 20, or the linear driving member 220 can drive the mounting frame 230 to drive the beam splitter 400 to move along the linear guide rail 210 away from the first light path 20, so that the beam splitter 400 reaches the avoiding position avoiding the first light path 20. During the movement of the beam splitter 400 driven by the linear driving member 220, the linear guide rail 210 can guide and limit the movement track of the beam splitter 400, thereby improving the positional accuracy of the beam splitter 400 reaching the light splitting position, and correspondingly improving the accuracy of the propagation paths of the first light beam 11 and the second light beam 12 split by the beam splitter 400, and ensuring the stable and accurate output of the output device in the double-channel mode.

[0039] As shown in the embodiment, the linear driving member 220 is located at one end of the linear guide rail 210 away from the first light path 20 and the second light path 30. This arrangement reduces the interference and shielding of the first light path 20 and the second light path 30 caused by the arrangement and operation of the linear driving member 220, and improves the convenience of arranging the optical elements on the first light path 20 and the second light path 30 on the basis of ensuring the stable operation of the driving assembly 200. Figure 1 Figure 2 As shown in the embodiment, the linear driving member 220 is located at one end of the linear guide rail 210 away from the first light path 20 and the second light path 30. This arrangement reduces the interference and shielding of the first light path 20 and the second light path 30 caused by the arrangement and operation of the linear driving member 220, and improves the convenience of arranging the optical elements on the first light path 20 and the second light path 30 on the basis of ensuring the stable operation of the driving assembly 200.

[0040] Specifically, the linear guide rail 210 is provided with a limiting seat for abutting and limiting the mounting frame 230, so that the beam splitter 400 is located at the light splitting position. In use, the linear driving member 220 drives the mounting frame 230 to move along the linear guide rail 210 towards the first light path 20, and when the mounting frame 230 abuts against the limiting seat, it cannot continue to move, the linear driving member 220 stops driving the mounting frame 230, and the beam splitter 400 is located at the light splitting position, thereby improving the positional accuracy of the beam splitter 400 reaching the light splitting position driven by the linear driving member 220, and reducing the control accuracy of the driving stroke of the linear driving member 220.

[0041] ​In the embodiment, the mounting frame 230 is fixedly connected with a sliding seat, the sliding seat is slidably connected with the linear guide rail 210, and the sliding seat is provided with a limiting lug in a cylindrical shape on the side facing the limiting seat, and the circumferential extension angle of the outer arc surface of the limiting lug is greater than 200°; the limiting seat is provided with two limiting arms on the side facing the sliding seat, the two limiting arms enclose a limiting space in an inner ring profile in a cylindrical shape, and the circumferential encircling angle of the two limiting arms is in the range of 190°-200° along the limiting space, then the end of the two limiting arms away from the limiting seat forms an opening, and the end of each limiting arm away from the limiting seat forms a limiting arc segment in the shape of a necked opening; and the limiting space is matched with the limiting lug.

[0042] In the double-channel mode, in the process that the linear driving member 220 drives the sliding seat to drive the mounting frame 230 and the beam splitter 400 to move towards the first light path 20, the outer arc surface of the limiting lug first enters the limiting space through the opening between the two limiting arms, when the diameter region of the limiting lug perpendicular to the extension direction of the linear guide rail 210 reaches the opening, the two limiting arms are pressed to the two sides to make the opening slightly open, until the limiting lug is inserted into the limiting space, and the beam splitter 400 reaches the light splitting position; wherein the two limiting arms enclose the outer periphery of the limiting lug, and the end of the two limiting arms away from the limiting seat can limit the limiting lug in the limiting space, thereby improving the position accuracy and stability of the beam splitter 400 at the light splitting position; when it is needed to adjust to the single-channel mode, the linear driving member 220 drives the sliding seat to drive the mounting frame 230, the beam splitter 400 and the limiting lug to move away from the limiting seat, the limiting lug presses and opens the opening formed by the two limiting arms, thereby moving out of the limiting space and to the avoiding position avoiding the first light path 20.

[0043] Specifically, the linear driving member 220 can be a stepping motor.

[0044] In the embodiment, as shown in Figure 1 and Figure 2 , the incident port 110 and the first exit port 120 are located on opposite sides of the housing 100, and the incident port 110 and the first exit port 120 are coaxial. The incident port 110 and the first exit port 120 are arranged at positions of the housing 100, the position accuracy of which is easy to guarantee, and the first light path 20 extends in a horizontal straight line, so the position accuracy of the optical element arranged in the first light path 20 is also easy to guarantee, thereby improving the processing and assembling convenience and accuracy of the laser single / double-channel coupling output device, and ensuring the accurate and stable laser output thereof.

[0045] In the embodiment, as shown in Figure 1 and Figure 2As shown, the first exit port 120 and the second exit port 130 are located on the same side of the shell 100, and the shell 100 is provided with a reflecting mirror 610, and the second light beam 12 is reflected to the second exit port 130 through the reflecting mirror 610.

[0046] In this embodiment, as shown in Figure 1 and Figure 2 , the incident port 110 is inserted with an incident lens barrel 140, the incident lens barrel 140 includes a coaxial limiting barrel segment 142 and a plug-in barrel segment 143, the outer diameter of the plug-in barrel segment 143 is smaller than the outer diameter of the limiting barrel segment 142, and the plug-in barrel segment 143 is plugged into the incident port 110, the end face of the limiting barrel segment 142 abuts against the outer end face of the incident port 110, and the limiting barrel segment 142 and / or the plug-in barrel segment 143 is provided with a collimation module 300. The end of the limiting barrel segment 142 away from the plug-in barrel segment 143 is provided with an interface 141 connected to the laser, and when assembled, the collimation module 300 is first loaded into the incident lens barrel 140, and then the plug-in barrel segment 143 of the incident lens barrel 140 is inserted into the incident port 110 from the outside to the inside, until the end face of the limiting barrel segment 142 towards the plug-in barrel segment 143 abuts against the shell 100, thereby limiting the relative position of the incident lens barrel 140 and the incident port 110 in the axial and radial directions, and accordingly ensuring the alignment of the collimation module 300 with the laser emitted by the laser, and the position arrangement accuracy of the collimation module 300; wherein the collimation module 300 can collimate the incident light 10 to emit the incident light 10 in parallel.

[0047] In this embodiment, as shown in Figure 1 and Figure 2 , the first light path 20 is provided with a first focusing module 510, and the first focusing module 510 is located between the light splitting position and the first exit port 120, and specifically between the light splitting position and the first transmitting mirror 520, for focusing the incident light 10 or the first light beam 11 to improve the convergence of the incident light 10 or the first light beam 11.

[0048] Similarly, as shown in Figure 1 and Figure 2 , the second light path 30 is provided with a second focusing module 620. The second focusing module 620 is located between the reflecting mirror 610 and the second transmitting mirror 630, and is used for focusing the second light beam 12 to improve the convergence of the second light beam 12.
