Description

Technical Field

[0001] This application relates to the field of laser technology, and in particular to cooling and heat dissipation installation structures, fiber lasers, and laser therapy equipment. Background Technology

[0002] With technological advancements and improved living standards, laser equipment is increasingly being used in various fields, such as medicine and medical device manufacturing. However, the placement and orientation of laser equipment may be subject to specific limitations when applied to different fields or products. For instance, in some products or fields, insufficient horizontal space may necessitate vertical placement of the laser equipment. In such cases, conventional laser equipment may not meet the requirements, potentially leading to issues such as fiber optic wobbling and thermal grease leakage. Utility Model Content

[0003] Therefore, it is necessary to provide a cooling and heat dissipation mounting structure, a fiber laser, and a laser therapy device to address at least one of the above-mentioned technical problems, so as to reduce the problem of fiber optic swaying.

[0004] In a first aspect, this disclosure provides a cooling and heat dissipation mounting structure, including a mounting member, a cover member, and a first optical fiber. The mounting member has an optical fiber groove formed on it for mounting the first optical fiber. When the cover member covers the optical fiber groove, the cover member restricts the movement of the first optical fiber in the optical fiber groove, or the cover member has a mounting portion formed on it to restrict the movement of the first optical fiber in the optical fiber groove.

[0005] Optionally, the mounting member and the cover member are interconnected, the mounting member has a protrusion, and the cover member has one or more mounting portions to engage with the protrusion, thereby limiting the relative position of the mounting member and the cover member.

[0006] Optionally, the first optical fiber includes a first optical fiber segment, a second optical fiber segment, and a third optical fiber segment connected in sequence. The second optical fiber segment is located in the optical fiber groove. The mounting member forms a first channel and a second channel respectively communicating with the optical fiber groove. The first channel is used to accommodate part or all of the first optical fiber segment, and the second channel is used to accommodate part or all of the third optical fiber segment. Compared to the optical fiber groove, the mounting member forms the second channel by being closer to or farther from the mounting member, so that the third optical fiber segment located in the second channel avoids the second optical fiber segment.

[0007] Optionally, the mounting member is recessed in a direction away from the cover to form part or all of the second channel, such that the third optical fiber segment bypasses the second optical fiber segment from the side of the second optical fiber segment away from the cover.

[0008] Optionally, the mounting member forms a protrusion in the direction of the cover member, and forms part or all of the second channel through the protrusion, so that the third optical fiber segment bypasses the second optical fiber segment from the side of the second optical fiber segment facing the cover member, wherein the protrusion forms an avoidance gap to allow the third optical fiber segment to pass through.

[0009] Optionally, the mounting component has a first optical fiber port and a second optical fiber port, which are respectively connected to the optical fiber slot. The first optical fiber port is provided with a first adhesive to seal the gap between the optical fiber and the first optical fiber port, and the second optical fiber port is provided with a second adhesive to seal the gap between the optical fiber and the second optical fiber port.

[0010] Optionally, the mounting component is provided with a sealing ring located outside the optical fiber groove. The sealing ring cooperates with the mounting component, the cover, the first optical fiber segment, and the first colloid to seal the first optical fiber port. The sealing ring cooperates with the second optical fiber port, the mounting component, the cover, the third optical fiber segment, and the second colloid to seal the second optical fiber port. The optical fiber groove is filled with a thermally conductive liquid. The mounting component, the cover, and the first optical fiber cooperate to form a sealed cavity to limit leakage of the thermally conductive liquid. The thermally conductive liquid is thermally conductive silicone grease. The mounting component is a cooling plate made of metal or alloy.

[0011] Optionally, the cover has a plurality of mounting portions, with a protrusion located in the middle of the plurality of mounting portions to abut against the plurality of mounting portions to restrict relative movement between the cover and the mounting member.

[0012] Optionally, the fiber optic groove can be one of the following: circular, elliptical, racetrack-shaped, or spiral-shaped.

[0013] In a second aspect, this disclosure provides a fiber laser, including a cooling and heat dissipation mounting structure as described in any embodiment of the first aspect. The cooling and heat dissipation mounting structure is vertically arranged such that the mounting member and the cover member are arranged on opposite sides in the horizontal direction. The mounting member and the cover member are plate-shaped structures, and both the first fiber port and the second fiber port are higher than the fiber slot.

[0014] Thirdly, this disclosure provides a laser therapy device, including a medical optical fiber and a fiber laser as described in the second aspect.

[0015] In some embodiments of this disclosure, the cooling and heat dissipation installation structure uses a cover member or a mounting part of the cover member to restrict the position of the first optical fiber, preventing the first optical fiber from detaching from the optical fiber slot and ensuring that the laser output from the first optical fiber is relatively stable.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] In the description of this application, it should be understood that the terms "X-axis," "Y-axis," "Z-axis," "vertical," "parallel," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] Regarding existing laser designs, refer to Chinese patent publication CN201620444788.X, which features a plate-like design with internal recesses or fiber optic grooves to house the optical fiber. Generally, because the laser is placed horizontally, the recesses or fiber optic grooves face upwards, making it difficult for the optical fiber to sway. However, in certain special applications, such as when there is insufficient lateral space inside medical equipment, and the laser is designed to be placed vertically, this type of laser may cause the optical fiber inside to sway due to its vertical orientation. Furthermore, existing active fiber optic auxiliary heat dissipation methods for lasers involve potting the fiber with encapsulating adhesive for horizontal placement, or using thermal grease, or a combination of both. Thermal grease adheres better to the fiber than potting adhesive and promotes more uniform heat dissipation. However, if the thermal grease is not properly sealed or the coverage is insufficient, it may dry out locally during evaporation, leading to poor local heat dissipation and affecting the laser's light output, thus impacting the treatment effect.

[0034] refer to Figure 1 -8. Specifically, the cooling and heat dissipation mounting structure 100 includes a mounting member 110, a cover member 120, and a first optical fiber 200. The mounting member 110 has an optical fiber groove 111 for mounting the first optical fiber 200. When the cover member 120 covers the optical fiber groove 111, the cover member 120 restricts the movement of the first optical fiber 200 in the optical fiber groove 111, or the cover member 120 has a mounting portion 110 to restrict the movement of the first optical fiber 200 in the optical fiber groove 111.

[0035] Furthermore, the mounting member 110 and the cover member 120 are interconnected. The mounting member 110 has a protrusion 112, and the cover member 120 has one or more mounting portions 121 to cooperate with the protrusion 112 to limit the relative position of the mounting member 110 and the cover member 120.

[0036] In the above scheme, firstly, the relative position of the cover 120 and the mounting part 110 is determined by the engagement of the protrusion 112 of the mounting part 110 with the mounting portion 121 of the cover 120. Secondly, it should be noted that the mounting part 110 can be connected to the cover 120 by means of screws, clips, etc., to lock the relative position of the mounting part 110 and the cover 120. Optionally, the mounting part 110 has a screw hole 115, and the cover 120 has a through hole 122, through which screws can pass to connect with the screw hole 115 of the mounting part 110.

[0037] Furthermore, the opening of the fiber optic slot 111 faces the cover member 120, and the mounting portion 121 on the cover member 120 presses against the surface of the mounting member 110 to make it difficult for the first optical fiber 200 to detach from the fiber optic slot 111. In some embodiments, part or all of the cover member 120 may also press against the surface of the mounting member 110 to restrict the movement of the first optical fiber 200 from the fiber optic slot 111.

[0038] Optional, such as Figure 8a As shown, the first optical fiber 200 includes a first optical fiber segment 210, a second optical fiber segment 220, and a third optical fiber segment 230 connected in sequence. The second optical fiber segment 220 is located in the optical fiber groove 111. The mounting member 110 forms a first channel 130 and a second channel 140 respectively communicating with the optical fiber groove 111. The first channel 130 is used to accommodate part or all of the first optical fiber segment 210, and the second channel 140 is used to accommodate part or all of the third optical fiber segment 230. (See attached image for details.) Figure 4-9 .

[0039] Specifically, in some embodiments, such as Figure 8a and Figure 8b As shown, the second fiber segment 220 is spirally arranged. More specifically, the second fiber segment 220 spirals inward from its first end 221 to its second end 222, with the first end 221 connected to the first fiber segment 210 and the second end 222 connected to the third fiber segment 230. Therefore, the second end 222 of the second fiber segment 220, where it connects to the third fiber segment 230, is located internally, requiring the third fiber segment 230 to extend outward to connect with the outside. However, if the third fiber segment 230 and the second fiber segment 220 are both located on the same plane perpendicular to the first direction M, the second fiber segment 220 will obstruct the extension of the third fiber segment 230. Therefore, this disclosure provides a second channel 140 to allow the third fiber segment 230 to bypass the second fiber segment 220 and extend from the interior of the mounting member 110 to the exterior of the mounting member 110 to connect with other structures (e.g., gratings). For details, please refer to [reference needed]. Figure 8b This makes the installation of the first optical fiber 200 more convenient and reasonable.

[0040] It should be noted that in some embodiments, the first fiber segment 210, the second fiber segment 220, and the third fiber segment 230 are integrally formed. Furthermore, the fiber groove 111, the first channel 130, and the second channel 140 should be formed on the surface of the mounting member 110 facing the cover member 120.

[0041] Furthermore, it should be added that there are various designs that allow the third fiber segment 230 to avoid or bypass the second fiber segment 220. For example, in the first embodiment, such as Figure 3-7As shown, the mounting member 110 forms a protrusion 150 in the direction of the cover member 120, and the protrusion 150 forms part or all of the second channel 140. Specifically, the second channel 140 is located closer to the cover member 120 than the fiber optic groove 111, so that the third fiber optic segment 230 is located close to the cover member 120 in the first direction M, thereby allowing the third fiber optic segment 230 to bypass the second fiber optic segment 220 from the side of the second fiber optic segment 220 facing the cover member 120.

[0042] More specifically, such as Figure 5-7 As shown, the second channel 140 is divided into a first segment 142 and a second segment 143 that are interconnected. The first segment 142 is formed by the mounting member 110 being recessed in the direction away from the cover member 120. The second segment 143 is formed by the protrusion 150. The position of the first segment 142 does not correspond to the position of the fiber optic groove 111, while the position of the second segment 143 corresponds to the position of the fiber optic groove 111. Since the second fiber segment 220 needs to pass through the second channel 140 to be installed in the fiber optic groove 111 when the first fiber optic 220 is installed in the mounting member, a clearance notch 141 needs to be formed in the protrusion 150 (the area corresponding to the second segment 143) to allow the second fiber segment 220 to pass through the protrusion 150 to reach the fiber optic groove 111, and the position of the clearance notch 141 should correspond to the position of the fiber optic groove.

[0043] More specifically, the first channel 130 and the fiber optic groove 111 are equidistant from the cover member 120, while the second segment 143 is closer to the cover member 120 than the first channel 130 and the fiber optic groove 111. Therefore, compared to the first fiber segment 210 located in the first channel 130 and the second fiber segment 220 located in the fiber optic groove 111, the portion of the third fiber segment 230 located in the second segment 143 can be positioned closer to the cover member 120, and the second fiber segment 220 no longer obstructs the third fiber segment 230, thus allowing the third fiber segment 230 to bypass the second fiber segment 220 and extend from the inside out.

[0044] For ease of understanding, some embodiments are described below. For example, the mounting member 110 and the cover member 120 are arranged side by side. The mounting member 110 is located on the left side, and the cover member 120 is located on the right side. In this case, the right side surface of the mounting member 110 is recessed to the left to form the first channel 130, the fiber optic groove 111, and the first segment 142. The second segment 143 is formed by a protrusion 150 protruding to the right from the right side surface of the mounting member 110. Therefore, the third fiber optic segment 230 located in the second segment 143 can be closer to the cover member 120 than the second fiber optic segment 220 located in the fiber optic groove 111, by bypassing the second fiber optic segment 220 on the right side, specifically as follows. Figure 8a and Figure 8bAs shown. It should be noted that, at this time, the first direction M is from left to right.

[0045] In the second embodiment, such as Figures 13-16 As shown, the mounting member 110 is recessed in the direction away from the cover member 120 (i.e., in the opposite direction of the first direction M) to form a second channel 140, such that the second channel 140 is located further away from the cover member 120 compared to the fiber optic groove 111. Consequently, the third fiber segment 230 located in the second channel 140 is located further away from the cover member 120 compared to the second fiber segment 220 located in the fiber optic groove 111. This allows the third fiber segment 230 to avoid or bypass the second fiber segment 220 located in the fiber optic groove 111. Therefore, the third fiber segment 230 can extend from the inside out and bypass the second fiber segment 220 until it reaches the outside of the fiber optic groove, specifically as follows: Figure 17a and Figure 17b As shown.

[0046] For ease of understanding, this disclosure is marked with a first direction M. In some embodiments, the first direction M is the direction in which the fiber optic groove faces the cover.

[0047] In this preferred embodiment, the fiber optic groove 111 has a spiral structure, extending spirally from the first end of the fiber optic groove 111 to the second end. In some embodiments, the first end of the fiber optic groove 111 communicates with the first channel 130, and the second end of the fiber optic groove 111 communicates with the second channel 140. Furthermore, the first channel 130 is formed by a recess in the mounting member 110 in a direction away from the cover member 120. Since the first channel 130 and the fiber optic groove 111 have the same recess depth in the direction away from the first direction M, the distance between the first fiber segment 210 in the first channel 130 and the second fiber segment 220 in the fiber optic groove 111 and the cover member 120 is the same. Because the second channel 140 is further away from the cover member 120 than the first channel 130 and the fiber optic groove 111, the third fiber segment 230 in the second channel 140 can be located further away from the cover member 120 than the second fiber segment 220, specifically as follows... Figure 17a and Figure 17b As shown.

[0048] For ease of understanding, some embodiments are described below. For example, in some embodiments, the mounting member 110 and the cover member 120 are arranged side by side. The mounting member 110 is located on the left side, and the cover member 120 is located on the right side. In this case, the right side surface of the mounting member 110 is recessed to the left to form a first channel 130, an optical fiber groove 111, and a second channel 140. The depth of the leftward recess of the second channel 140 is greater than the depth of the recess of the first channel 130 and the optical fiber groove 111, so that the third optical fiber segment 230 located in the second channel 140 can be located to the left of the second optical fiber segment 220 to bypass the second optical fiber segment 220, such as... Figure 17a and Figure 17b As shown. It should be noted that, at this time, the first direction M is from left to right.

[0049] It should be noted that when installing the first optical fiber in the mounting component 110, the user needs to first lay the first optical fiber segment in the first channel 130 and the second optical fiber segment in the fiber optic trough, and then lay the third optical fiber segment "above" the second optical fiber segment. If the second channel 140 does not have a clearance gap 141 to allow the second optical fiber segment to pass through the clearance gap 141 and reach the fiber optic trough, the installation difficulty of laying the second optical fiber segment will increase, which is not conducive to the installation of the second optical fiber segment.

[0050] Optionally, the fiber optic channel 111 can be one of the following shapes: circular, elliptical, racetrack-shaped, or spiral-patterned. Specifically, as shown... Figure 4 and Figure 5 As shown, the fiber optic groove 111 has a circular spiral design, so the second fiber segment 220 of the first fiber 200 can be coiled around the fiber optic groove 111 from the outside to the inside or from the inside to the outside.

[0051] It should be noted that the first fiber segment 210 and the third fiber segment 230 of the first optical fiber 200 can be connected to a high-reflection grating and a low-reflection grating, respectively, to form a resonant cavity for laser wavelength selection. For example, if the first fiber segment 210 is the input end and the third fiber segment 230 is the output end, then the first fiber segment 210 can be connected to the high-reflection grating to reflect the target wavelength light into the second fiber segment 220, while the third fiber segment 230 can be connected to the low-reflection grating to transmit a portion of the target wavelength laser light.

[0052] like Figure 11 and Figure 12 As shown, the mounting component 110 has a first optical fiber port 116 and a second optical fiber port 117, which are respectively connected to the optical fiber groove 111. The first optical fiber port 116 is provided with a first colloid to seal the gap between the first optical fiber 200 and the first optical fiber port 116, and the second optical fiber port 117 is provided with a second colloid to seal the gap between the first optical fiber 200 and the second optical fiber port 117. Specifically, the cooling and heat dissipation mounting structure 100 of this disclosure may incorporate liquid thermally conductive materials, such as thermally conductive liquids, specifically thermally conductive silicone grease. Therefore, it is necessary to add a first colloid to the first optical fiber port 116 and a second colloid to the second optical fiber port 117 to seal the first optical fiber port 116 and the second optical fiber port 117 and prevent leakage of the liquid thermally conductive material. In addition, the above design can also prevent dust from entering the cooling and heat dissipation mounting structure 100 through the first optical fiber port 116 and the second optical fiber port 117.

[0053] It should be noted that the first colloid and the second colloid can be solid adhesives.

[0054] Optionally, the mounting component 110 is provided with a sealing ring 113, which is located outside the fiber optic groove 111. The sealing ring 113 cooperates with the mounting component 110, the cover component 120, the first fiber segment 210, and the first adhesive to seal the first fiber optic port 116. The sealing ring 113 cooperates with the second fiber optic port 117, the mounting component 110, the cover component 120, the third fiber segment 230, and the second adhesive to seal the second fiber optic port 117.

[0055] The fiber optic channel 111 is filled with a heat-conducting liquid, wherein the mounting component 110, the cover component 120 and the first optical fiber 200 cooperate to form a sealed cavity to limit the leakage of the heat-conducting liquid.

[0056] Optionally, when the cover 120 is closed onto the fiber optic groove 111, the cover 120 restricts the movement of the first fiber 200 in the fiber optic groove 111, or the cover 120 restricts the movement of the first fiber 200 in the fiber optic groove 111 via the mounting part 121.

[0057] Optionally, the cover 120 has multiple mounting portions 121, with a protrusion 112 located in the middle of the mounting portions 121 to abut against them and restrict the relative movement of the cover 120 and the mounting member 110. Taking the cooling and heat dissipation mounting structure 100 as an example where it is placed vertically, the mounting member 110 and the cover 120 can be located on the left and right sides respectively. The mounting member 110 on the left side can protrude to the right to form a protrusion 112, while the cover 120 on the right side can protrude to the left to form a mounting portion 121. In some embodiments, the mounting portion 121 is a strip structure and the cover 120 has multiple mounting portions 121, with a gap in the middle of the multiple mounting portions 121 for the protrusion 112 to be inserted and abut against, thereby restricting the relative movement of the mounting portion 121 and the cover 120 in the front-back and up-down directions.

[0058] Optionally, the mounting member 110 has an annular flange 118, and the mounting portion 121 abuts against the annular flange 118. Specifically, the inner side of the mounting portion 121 can abut against the protrusion 112, and the outer side of the mounting portion 121 can abut against the annular flange, thereby allowing the cover member 120 to be more securely mounted on the mounting member 110. In addition, both the mounting member 110 and the cover member 120 are provided with grooves for mounting the sealing ring 113. And the groove of the mounting member 110 communicates with the second optical fiber port 117, so the first optical fiber 200 located near the second optical fiber port 117 will pass through the groove of the mounting member 110 and pass through the gap between the sealing ring 113 and the mounting member 110, improving the sealing degree near the second optical fiber port 117 and minimizing the leakage of heat-conducting liquid from the gap between the first optical fiber 200 and the second optical fiber port 117.

[0059] Furthermore, this disclosure also provides a fiber laser, including a cooling and heat dissipation mounting structure 100. In some specific application scenarios, it is necessary to arrange the cooling and heat dissipation mounting structure 100 vertically for easy placement. In this case, the mounting member 110 and the cover member 120 are arranged vertically opposite each other, for example, the mounting member 110 is located on the left and the cover member 120 is located on the right, or vice versa. Moreover, the mounting member 110 and the cover member 120 are preferably configured as plate-like structures to further reduce the space occupied by the cooling and heat dissipation mounting structure 100 laterally.

[0060] When the cooling and heat dissipation mounting structure 100 is applied to a fiber laser, both the first fiber port 116 and the second fiber port 117 are higher than the fiber groove to allow the heat-conducting liquid to be effectively stored between the mounting member 110 and the cover member 120, thus avoiding the risk of heat-conducting liquid leakage when the first fiber port 116 and the second fiber port 117 are not higher than the fiber groove. In some embodiments, the mounting member 110 has a mounting cavity formed by an annular flange 118 to mount the cover member 120, and both the first fiber port 116 and the second fiber port 117 are located at the top of the mounting cavity. More specifically, as... Figures 13-14 As shown, the top of the mounting cavity is horizontally extended, so that both the first fiber optic port 116 and the second fiber optic port 117 can be located at the highest position of the mounting cavity.

[0061] Furthermore, the mounting element 110 can be a cooling plate. Specifically, the mounting element 110 is made of metal or an alloy. The cover element 120 can also be made of metal or an alloy.

[0062] Furthermore, this disclosure also provides a laser therapy device, including the aforementioned fiber laser. The laser emitted by the fiber laser is coupled and then transmitted via a medical optical fiber for therapeutic purposes.

[0063] In some embodiments, in order to improve the heat dissipation effect of the cooling and heat dissipation mounting structure 100 and avoid problems such as light spots caused by uneven heat dissipation, the sealed cavity formed by the mounting part 110 and the cover part 120 is filled with heat-conducting liquid, so that the temperature of the first optical fiber 200 is consistent throughout, ensuring the stability of the light spot and preventing the medical optical fiber that emits a certain amount of laser energy for treatment into the patient's body due to the instability of the light spot from being burned out, causing safety problems.

[0064] In the above scheme, the protrusion 112 of the mounting member 110 cooperates with one or more mounting portions 121 of the cover member 120 to limit the relative position between the mounting member 110 and the cover member 120. Furthermore, the mounting portion 121 of the cover member 120 presses against the mounting member 110, thereby restricting the movement of the first optical fiber 200 in the optical fiber groove 111 to ensure the stability of the laser output from the first optical fiber 200. Secondly, sealing rings 113 and colloids are provided in the first optical fiber port 116 and the second optical fiber port 117 to further improve the sealing performance of the cooling and heat dissipation mounting structure 100. In addition, both the first optical fiber port 116 and the second optical fiber port 117 are higher than the optical fiber groove to reduce the possibility of heat-conducting liquid leakage.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
