Description

Technical Field

[0001] This application relates to the technical field of semiconductor lasers, and in particular to a multi-power semiconductor laser therapy device that facilitates spot switching. Background Technology

[0002] Semiconductor laser therapy devices are medical devices based on semiconductor laser technology. They emit low-intensity lasers of specific wavelengths and utilize photobiological modulation to achieve therapeutic effects such as anti-inflammation, analgesia, and tissue repair. The core principle is that laser photons are absorbed by cytochrome C oxidase in the mitochondria of cells, promoting ATP synthesis and thereby activating cellular metabolism and repair mechanisms.

[0003] A multi-power replaceable head semiconductor laser with easy spot switching, currently disclosed in CN118920261A, includes a semiconductor laser, an L-shaped handpiece body, a slow-axis compression lens, a TEC cooling chip, a cooling plate, and multiple replaceable treatment heads. The replaceable treatment heads are mechanically positioned by magnetic attachment to the handpiece body for replacement. Because the treatment heads are replaceable, they need to be changed periodically according to different treatment areas on the human body. The spot size can be switched using the detachable and replaceable treatment heads.

[0004] Regarding the aforementioned technologies, since the laser handpiece is the final output component of laser energy, the semiconductor laser needs to be shut down when the treatment head is replaced to prevent the laser emitted accidentally during treatment head removal from causing permanent and irreversible damage to the retina or skin. However, shutting down the semiconductor laser makes the treatment head replacement operation more complicated. Summary of the Invention

[0005] To facilitate rapid replacement of the treatment head, this application provides a multi-power semiconductor laser treatment device that allows for easy spot switching.

[0006] This application provides a multi-power semiconductor laser therapy device that facilitates spot switching, employing the following technical solution:

[0007] A multi-power semiconductor laser therapy device that facilitates spot switching includes:

[0008] A semiconductor laser, one end of which is connected to an optical fiber;

[0009] A treatment handpiece includes a mounting base and a treatment head, wherein the mounting base is connected to the end of the optical fiber away from the semiconductor laser, and the treatment head is mounted on the mounting base;

[0010] A connecting assembly includes a connector, a connector ear, and an adapter. The connector is fixedly connected to the mounting base. The connector ear is mounted on the treatment head and abuts against the connector to connect the mounting base to the treatment head. The adapter is mounted on the treatment head and connected to the connector ear to control the connector ear to abut against or disengage from the connector.

[0011] A light-shielding assembly includes a light-shielding valve, a switching element, and a control element. The light-shielding valve is installed in the mounting base. The switching element is connected to the light-shielding valve. One end of the control element is connected to the switching element, and the other end is connected to the switching element. When the switching element controls the connecting ear to abut against the mounting base, the switching element controls the light-shielding valve to open. When the switching element controls the connecting ear to disengage from the mounting base, the switching element controls the light-shielding valve to close.

[0012] By adopting the above technical solution, a semiconductor laser is used to emit laser light, which is then delivered to the treatment handpiece via optical fiber. The treatment handpiece is then used to treat the treatment area on the human body. When changing the treatment area, the spot size needs to be switched, which requires replacing the treatment head.

[0013] At this point, the conversion element controls the connecting ear to disengage from the connector, while the control element drives the switching element to close the light-shielding valve. This releases the connector and connecting ear from locking, and the light-shielding valve blocks the laser channel of the connector, thus preventing accidental laser emission. At this point, the different treatment heads that need to be replaced can be removed.

[0014] Next, the appropriate treatment head is installed on the mounting base. Then, the conversion component controls the connecting ear to abut against the connecting base. At the same time, the control component drives the switching component to open the light-shielding valve, so that the connecting base and the connecting ear are locked, and the light-shielding valve connects the laser channel of the connecting base. Then, the treatment handpiece can be used to treat the changed treatment area on the human body.

[0015] During the treatment head replacement process, when the conversion component simultaneously controls the connecting ear to disengage from the connector, the switching component controls the light-shielding valve to close, preventing accidental laser emission; conversely, when the conversion component simultaneously controls the connecting ear to engage with the connector, the switching component controls the light-shielding valve to open, allowing the laser to smoothly reach the treatment head. This achieves the goal of replacing the treatment head without stopping the machine, enabling rapid replacement.

[0016] Optionally, the conversion component includes a mounting box, a conversion part, and a control part. The mounting box is fixedly connected to the treatment head, the conversion part is rotatably connected inside the mounting box, the connecting ear is hinged to the conversion part, and the control part is used to abut against the conversion part to drive the conversion part to move the connecting ear to abut against or disengage from the connecting seat.

[0017] By adopting the above technical solution, the control unit uses the contact control conversion unit to rotate. The rotation of the conversion unit drives the connecting ear to move inside the mounting box. Then, the control unit controls the connecting ear to press against the connecting seat or detach from the connecting seat through the conversion unit.

[0018] Optionally, the conversion part includes a control block, a conversion rod, a locking rod, and an unlocking rod. One end of the control block is hinged to the connecting lug, and the other end is hinged to the conversion rod. An oblong hole is provided at the junction of the control block and the conversion rod. A control spring is sleeved on the control block. One end of the control spring abuts against the control block, and the other end abuts against the conversion rod. The locking rod and the unlocking rod are both fixedly connected to the conversion rod, and the control member presses the locking rod or the unlocking rod to rotate the conversion rod to different directions.

[0019] By adopting the above technical solution, when the treatment head needs to be replaced, the control connecting ear of the conversion unit is in a position that is pressed against the connecting seat, while the unlocking lever is located closer to the control unit. At this time, pressing the unlocking lever with the control unit causes the unlocking lever to rotate, which in turn compresses the control spring. When the control block's tilt direction changes, the control spring returns to its original position, causing the control block to disengage the connecting ear from the connecting seat, thus releasing the locking between the connecting ear and the connecting seat, allowing the treatment head to be disassembled. Simultaneously, the unlocking lever rotates away from the control unit, while the locking lever rotates towards the control unit, bringing the locking lever closer to the control unit.

[0020] Next, the new treatment head is installed on the mounting base. Then, the locking lever is pressed using the control unit. The locking lever is pressed and drives the conversion lever to rotate in the opposite direction. The rotation of the conversion lever causes the control spring to be pressed again. When the control block tilts again, the control spring resets, which causes the control block to drive the connecting ear to abut against the connecting base, thus completing the locking of the mounting base and the treatment head.

[0021] Optionally, limit rods are fixedly connected to both sides of the conversion part, and the limit rods are respectively located on the movement path of the locking rod or the unlocking rod, so that the locking rod or the unlocking rod abuts against the limit rod.

[0022] By adopting the above technical solution, the setting of the limit rod can avoid collision between the connecting ear and the hinge of the mounting box, reduce damage to the connecting ear, and also position the locking rod and unlocking rod, so that the control unit can accurately press the locking rod and unlocking rod.

[0023] Optionally, the connecting ear is provided with a sliding hole, and the connecting ear is hinged to the mounting box through the sliding hole. In the length direction of the treatment head, the hinge point between the mounting box and the connecting ear is located between the hinge point between the connecting ear and the control block and the hinge point between the control block and the conversion rod.

[0024] By adopting the above technical solution, since the hinge of the mounting box and the connecting ear is located between the hinge of the connecting ear and the control block and the hinge of the control block and the conversion rod, the control spring will continuously push the control block away from the conversion rod during the reset process. At this time, the end of the connecting ear that is close to the control block will also move away from the control block, while the end of the connecting ear that is far from the control block will rotate toward the control block, thereby driving the connecting seat to move closer to the control block, so that the mounting seat and the treatment head fit more closely.

[0025] Optionally, the control unit includes a fixed box, a guide post, a guide block, a control rod, and a stop plate. The fixed box is fixedly connected to the mounting box. The guide post passes through the fixed box and has a guide groove. The guide block is inserted into the guide groove so that the guide post reciprocates once. The guide block slides in the guide groove, causing the guide post to rotate 180°. The control rod is fixedly connected to the end of the guide post away from the conversion part. The stop plate is fixedly connected to the end of the guide post near the conversion part. During the rotation of the guide post, the stop plate abuts against the locking rod or the unlocking rod respectively. A reset spring is sleeved on the control rod. One end of the reset spring abuts against the fixed box, and the other end is fixedly connected to the control rod.

[0026] By adopting the above technical solution, pressing the control lever moves the guide column, which in turn compresses the reset spring. During the movement of the guide column, the guide block moves synchronously in the guide groove. At this time, the bottom of the abutment plate abuts against the locking or unlocking lever, causing the conversion lever to rotate.

[0027] Release the control column, and the control column will reset under the push of the reset spring. The control column will drive the guide column to reset synchronously. During the reset process of the guide column, the guide block moves in the guide groove, causing the guide column to rotate 180°, thereby switching the bottom of the abutment plate to be above the locking rod or the unlocking rod.

[0028] By utilizing the cooperation of the guide block and guide groove, the control lever rotates 180° with each press, allowing the abutment plate to accurately abut against the locking or unlocking lever, and avoiding interference with the unlocking or locking lever on the other side.

[0029] Optionally, the light-shielding valve is a ball valve, and the switching component includes a switching gear and a positioning part. The switching gear is fixedly connected to the ball valve, and the axis of the switching gear and the axis of the ball valve are on the same straight line. The switching gear has four positioning slots evenly distributed around its own axis. The control component controls the switching gear to rotate 90° each time, and the positioning part is inserted into the positioning slot.

[0030] By adopting the above technical solution, the control component drives the switching gear to rotate each time, and the positioning part then precisely positions the switching gear by inserting it into the positioning groove, thereby controlling the switching gear to rotate precisely 90° each time, so that the light-shielding valve can continuously switch between open and closed states.

[0031] Optionally, the positioning part includes a positioning block, a guide rod, a positioning spring, and a positioning insert. The positioning block is fixedly connected to the mounting base, the guide rod is inserted into the positioning block, the positioning spring is sleeved on the guide rod, and the positioning insert is fixedly connected to the side of the guide rod near the switching gear. One end of the positioning spring abuts against the positioning block, and the other end abuts against the positioning insert to drive the positioning insert into the positioning groove.

[0032] By adopting the above technical solution, each time the switching gear rotates, the positioning block disengages from the positioning slot, and then the drive guide rod moves toward the positioning block. At the same time, the positioning spring is compressed. When the other positioning slot on the switching gear rotates to the positioning block, the positioning block is quickly inserted into the other positioning slot under the drive of the positioning spring, thereby completing the locking of the switching gear and enabling the switching gear to rotate precisely 90°.

[0033] Optionally, the control component includes a pressure rod and an abutment tooth. The pressure rod is slidably connected to the connecting lug and passes through the connecting seat. The abutment tooth is rotatably connected to the side of the pressure rod near the switching gear. When the pressure rod moves toward the switching gear, the abutment tooth engages in the positioning groove, driving the switching gear to rotate. The other side of the abutment tooth is arc-shaped to facilitate disengagement from the positioning groove.

[0034] By adopting the above technical solution, each time the pressure bar is pressed, the abutting teeth abut against the positioning groove of the switching gear as the pressure bar moves, thereby driving the switching gear to rotate. When the pressure bar is reset, the other side of the abutting teeth is set in an arc shape and disengages from the positioning groove to avoid interfering with the switching gear, so that each time the pressure bar is pressed, the switching gear can be accurately driven to rotate 90°.

[0035] Optionally, the control component further includes a control ring, and both the control unit and the pressure rod are fixedly connected to the control ring.

[0036] By adopting the above technical solution, pressing the control ring can simultaneously control the conversion unit to perform conversion and control the pressure rod to drive the switching gear to rotate. When the conversion unit controls the connecting ear to disengage from the connecting seat, the pressure rod drives the switching gear to rotate until the ball valve is blocked. When the conversion unit controls the connecting ear to abut against the connecting seat, the pressure rod drives the switching gear to rotate until the ball valve is connected.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. Through the cooperation of a semiconductor laser, optical fiber, mounting base, treatment head, connector, connecting ear, conversion device, light-shielding valve, switching device, and control device, during the treatment head replacement process, when the conversion device simultaneously controls the connecting ear to disengage from the connector, the switching device controls the light-shielding valve to close, preventing accidental laser emission; conversely, when the conversion device simultaneously controls the connecting ear to abut the connector, the switching device controls the light-shielding valve to open, allowing the laser to smoothly reach the treatment head. This achieves the effect of rapid treatment head replacement without stopping the machine.

[0039] 2. Through the cooperation of the mounting base, treatment head, connecting ear, connecting seat, control unit, control block, conversion lever, locking lever, unlocking lever and control spring, the locking lever or unlocking lever is pressed by the control unit, which drives the control block to rotate through the conversion block. Then, the control spring is used to reset, controlling the connecting ear to abut or disengage from the connecting seat, thereby achieving the effect of easy control of unlocking and locking of the mounting base and treatment head;

[0040] 3. Through the cooperation of the light-blocking valve, switching gear, positioning groove, positioning block, guide rod, positioning spring and positioning insert, the positioning insert is quickly inserted into another positioning groove under the drive of the positioning spring each time the switching gear rotates, thereby locking the switching gear and achieving the effect that the switching gear can rotate 90° accurately each time.

[0049] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0050] This application discloses a multi-power semiconductor laser therapy device that facilitates spot switching.

[0051] Reference Figure 1-6A multi-power semiconductor laser therapy device with easy spot switching includes a semiconductor laser 1, a treatment handpiece 2, a connecting assembly, and a light-shielding assembly 4. One end of the semiconductor laser 1 is connected to an optical fiber 11. The treatment handpiece 2 includes a mounting base 21 and a treatment head 22. The mounting base 21 is connected to the optical fiber 11, and the treatment head 22 is mounted on the mounting base 21. The connecting assembly includes a connecting seat 31, a connecting ear 32, and a conversion component 33. The connecting seat 31 is fixedly connected to the mounting base 21, the connecting ear 32 is mounted on the treatment head 22, and the connecting ear 32 abuts against the connecting seat 31 to connect the mounting base 21 and the treatment head 22. The conversion component 33 is mounted on the treatment head 22 and connected to the connecting ear 32. The light-shielding assembly 4 includes a light-shielding valve 41, a switching component 42, and a control component 43. The light-shielding valve 41 is installed inside the mounting base 21, the switching component 42 is connected to the light-shielding valve 41, and one end of the control component 43 is connected to the switching component 42, and the other end is connected to the conversion component 33. During the replacement of treatment head 22, when the conversion component 33 simultaneously controls the connecting ear 32 to disengage from the connecting seat 31, the switching component 42 controls the light-shielding valve 41 to close, preventing accidental laser emission; when the conversion component 33 simultaneously controls the connecting ear 32 to abut against the connecting seat 31, the switching component 42 controls the light-shielding valve 41 to open, allowing the laser to smoothly reach treatment head 22. This achieves the effect of rapid replacement of treatment head 22 without stopping the machine.

[0052] The semiconductor laser 1 is equipped with multiple adjustment buttons 12, which can be used to adjust the power of the semiconductor laser 1. This allows for customized treatment plans to meet the needs of different diseases, different tissues, and even different stages of the same disease, based on complex clinical requirements. Ultimately, this achieves safer, more effective, more comfortable, and wider-ranging laser treatment applications.

[0053] In this embodiment, two connecting components are provided. In other embodiments, three, four, five, or more connecting components may be provided. In this embodiment, the two connecting components are symmetrically arranged about the axis of the mounting base 21, which makes the connection between the mounting base 21 and the treatment head 22 more stable. The control component 43 is located between the two connecting components, so that when the switching component 42 drives the connecting ear 32 to move, it can more stably drive the control component 43 to move.

[0054] The conversion component 33 includes a mounting box 331, a conversion part 332, and a control part 333. The mounting box 331 is fixedly connected to the treatment head 22, and the conversion part 332 is rotatably connected inside the mounting box 331. In this embodiment, the conversion part 332 includes a control block 3321, a conversion rod 3322, a locking rod 3323, and an unlocking rod 3324. One end of the control block 3321 is hinged to the connecting ear 32, and the other end is hinged to the conversion rod 3322. A waist-shaped hole is provided at the junction of the control block 3321 and the conversion rod 3322. A control spring 3325 is sleeved on the control block 3321. One end of the control spring 3325 abuts against the control block 3321, and the other end abuts against the conversion rod 3322. The locking rod 3323 and the unlocking rod 3324 are both fixedly connected to the conversion rod 3322. By pressing the locking lever 3323 or the unlocking lever 3324 using the control element 43, the conversion lever 3322 is rotated to different directions. The rotation of the conversion part 332 causes the connecting ear 32 to move within the mounting box 331. Subsequently, the control part 333 controls the connecting ear 32 to press against the connecting seat 31 or to disengage from the connecting seat 31 through the conversion part 332.

[0055] In this embodiment, the control unit 333 includes a fixed box 3331, a guide post 3332, a guide block 3333, a control rod 3334, and an abutment plate 3335. The fixed box 3331 is fixedly connected to the mounting box 331. The guide post 3332 passes through the fixed box 3331 and has a guide groove 3336. The guide block 3333 is inserted into the guide groove 3336 so that the guide post 3332 reciprocates once. The guide block 3333 slides in the guide groove 3336 to drive the guide post 3332. The control lever 3334 is fixedly connected to the end of the guide post 3332 away from the conversion part 332 when rotated 180°. The abutment plate 3335 is fixedly connected to the end of the guide post 3332 near the conversion part 332. During the rotation of the guide post 3332, the abutment plate 3335 abuts against the locking lever 3323 or the unlocking lever 3324 respectively. A reset spring 3337 is sleeved on the control lever 3334. One end of the reset spring 3337 abuts against the fixed box 3331, and the other end is fixedly connected to the control lever 3334. By utilizing the cooperation of the guide block 3333 and the guide groove 3336, the control lever 3334 rotates 180° each time it is pressed, so that the abutment plate 3335 can accurately abut against the locking lever 3323 or the unlocking lever 3324, and avoids interference with the unlocking lever 3324 or the locking lever 3323 on the other side.

[0056] When the treatment head 22 needs to be replaced, the connecting ear 32 is in the position of pressing against the connecting seat 31, and the abutment plate 3335 is located on one side of the unlocking lever 3324. At this time, press the control lever 3334, and the control lever 3334 moves, driving the guide post 3332 to move. At the same time, the reset spring 3337 is compressed. During the movement of the guide post 3332, the guide block 3333 moves synchronously in the guide groove 3336. At this time, the bottom of the abutment plate 3335 abuts against the unlocking lever 3324. The unlocking lever 3324 is pressed and drives the conversion lever 3322 to rotate. The rotation of the conversion lever 3322 causes the control spring 3325 to be compressed. When the conversion lever 3322 rotates to the point that the tilt direction of the control block 3321 changes, the control spring 3325 resets, thereby causing the control block 3321 to drive the connecting ear 32 to disengage from the connecting seat 31, so that the connecting ear 32 and the connecting seat 31 are unlocked, and the treatment head 22 can be disassembled.

[0057] During the disassembly of the treatment head 22, the locking lever 3323 rotates toward the abutment plate 3335. When the control column is released, the control column is reset under the push of the reset spring 3337. The control column drives the guide column 3332 to reset synchronously. During the reset of the guide column 3332, the guide block 3333 moves in the guide groove 3336, causing the guide column 3332 to rotate 180°, thereby making the abutment plate 3335 closer to the locking lever 3323.

[0058] Next, the new treatment head 22 is installed on the mounting base 21. Then, the control lever 3334 is pressed again. The control lever 3334 moves, driving the guide post 3332 to move. At the same time, the reset spring 3337 is compressed. During the movement of the guide post 3332, the guide block 3333 moves synchronously in the guide groove 3336. At this time, the bottom of the abutment plate 3335 abuts against the locking lever 3323. The locking lever 3323 is pressed, driving the conversion lever 3322 to rotate. The rotation of the conversion lever 3322 causes the control spring 3325 to be compressed. When the conversion lever 3322 rotates until the tilt direction of the control block 3321 changes, the control spring 3325 resets. This causes the control block 3321 to drive the connecting ear 32 to abut against the connecting base 31, thereby completing the locking of the mounting base 21 and the treatment head 22.

[0059] At the same time, the unlocking lever 3324 rotates toward the abutment plate 3335, releasing the control column again. When the control column is released, it resets under the push of the reset spring 3337. The control column drives the guide column 3332 to reset synchronously. During the reset process of the guide column 3332, the guide block 3333 moves in the guide groove 3336, causing the guide column 3332 to rotate 180°, thereby making the abutment plate 3335 closer to the unlocking lever 3324.

[0060] When removing or installing the treatment head 22, simply press the control post back and forth to switch the connection ear 32 and the connection base 31 between locking and unlocking.

[0061] In an optional embodiment, limiting rods are fixedly connected to both sides of the conversion part 332. The limiting rods are located on the movement path of the locking rod 3323 or the unlocking rod 3324, so that the locking rod 3323 or the unlocking rod 3324 abuts against the limiting rods. The limiting rods prevent the connecting ear 32 from colliding with the hinge of the mounting box 331, reducing damage to the connecting ear 32. They also position the locking rod 3323 and the unlocking rod 3324, facilitating precise pressing of the locking rod 3323 and the unlocking rod 3324 by the control part 333.

[0062] In this embodiment, the connecting ear 32 has a sliding hole. The connecting ear 32 is hinged to the mounting box 331 through the sliding hole. Along the length of the treatment head 22, the hinge point between the mounting box 331 and the connecting ear 32 is located between the hinge point between the connecting ear 32 and the control block 3321 and the hinge point between the control block 3321 and the conversion rod 3322. Because the hinge point between the mounting box 331 and the connecting ear 32 is located between the hinge point between the connecting ear 32 and the control block 3321 and the control block 3321 and the conversion rod 3322, during the reset process of the control spring 3325, the control block 3321 will continuously push away from the conversion rod 3322. At this time, the end of the connecting ear 32 closest to the control block 3321 will also move away from the control block 3321, while the end of the connecting ear 32 away from the control block 3321 will rotate towards the control block 3321, thereby causing the connecting seat 31 to move closer to the control block 3321, thus making the mounting seat 21 and the treatment head 22 fit more closely.

[0063] The light-shielding valve 41 is a ball valve, which is embedded in the mounting base 21. The switching component 42 includes a switching gear 421 and a positioning part 422. The switching gear 421 is fixedly connected to the ball valve, and the axis of the switching gear 421 is on the same straight line as the axis of the ball valve. The switching gear 421 has four positioning grooves 423 evenly distributed around its own axis. The positioning part 422 is inserted into the positioning groove 423 to control the switching gear 421 of the control component 43 to perform precise positioning of 90° each time it rotates.

[0064] In this embodiment, the positioning part 422 includes a positioning block 4221, a guide rod 4222, a positioning spring 4223, and a positioning insert 4224. The positioning block 4221 is fixedly connected to the mounting base 21. The guide rod 4222 is inserted into the positioning block 4221. The positioning spring 4223 is sleeved on the guide rod 4222. The positioning insert 4224 is fixedly connected to the side of the guide rod 4222 near the switching gear 421. One end of the positioning spring 4223 abuts against the positioning block 4221, and the other end abuts against the positioning insert 4224. The elasticity of the positioning spring 4223 drives the positioning insert 4224 to insert into the positioning groove 423.

[0065] Each time the control component 43 drives the switching gear 421 to rotate, the positioning block 4224 disengages from the current positioning slot 423, and then the drive guide rod 4222 moves toward the positioning block 4221. At the same time, the positioning spring 4223 is compressed. When the other positioning slot 423 on the switching gear 421 rotates to the positioning block 4224, the positioning block 4224 is quickly inserted into the other positioning slot 423 under the drive of the positioning spring 4223, thereby locking the switching gear 421 and allowing the switching gear 421 to rotate precisely 90°, so that the light-shielding valve 41 can continuously switch between open and closed states.

[0066] The control component 43 includes a pressure rod 431 and an abutment tooth 432. The pressure rod 431 is slidably connected to the connecting lug 32 and passes through the connecting seat 31. The abutment tooth 432 is rotatably connected to the side of the pressure rod 431 near the switching gear 421. In this embodiment, a spring piece 433 is provided between the abutment tooth 432 and the bottom of the pressure rod 431, so that the abutment tooth 432 is engaged in the positioning groove 423 when the pressure rod 431 moves toward the switching gear 421, thereby driving the switching gear 421 to rotate. The other side of the abutment tooth 432 is arc-shaped. During the resetting process of the abutment tooth 432, the arc-shaped abutment tooth 432 compresses the spring piece 433, thereby facilitating its disengagement from the positioning groove 423.

[0067] Each time the lever 431 is pressed, the abutting tooth 432 abuts against the positioning groove 423 of the switching gear 421 as the lever 431 moves, thereby driving the switching gear 421 to rotate. When the lever 431 is reset, the other side of the abutting tooth 432 is arc-shaped, which compresses the spring 433 and the abutting tooth 432 disengages from the positioning groove 423, avoiding interference with the switching gear 421. This ensures that each press of the lever 431 can accurately drive the switching gear 421 to rotate 90°.

[0068] The control component 43 also includes a control ring 434. In this embodiment, the two control levers 3334 and one pressure lever 431 are all fixedly connected to the control ring 434. The control ring 434 is configured such that when the control ring 434 is pressed, it can simultaneously control the two control levers 3334 to drive the conversion unit 332 to switch and control the pressure lever 431 to drive the switching gear 421 to rotate. When the conversion unit 332 controls the connecting ear 32 to disengage from the connecting seat 31, the pressure lever 431 drives the switching gear 421 to rotate until the ball valve is blocked. When the conversion unit 332 controls the connecting ear 32 to abut against the connecting seat 31, the pressure lever 431 drives the switching gear 421 to rotate until the ball valve is connected.

[0069] The implementation principle of a multi-power semiconductor laser therapy device that facilitates spot switching in this application embodiment is as follows: a semiconductor laser 1 emits a laser, and the power of the semiconductor laser 1 is adjusted by multiple adjustment buttons 12. Then, the laser is transmitted to the treatment handle 2 via an optical fiber 11. The treatment handle 2 is used to treat the treatment area of ​​the human body. When changing the treatment area, the spot size needs to be switched, so the treatment head 22 needs to be replaced.

[0070] At this time, pressing the control ring 434 will simultaneously press two control levers 3334 and one pressure lever 431. The control lever 3334 moves, driving the guide post 3332 to move, and simultaneously compressing the reset spring 3337. During the movement of the guide post 3332, the guide block 3333 moves synchronously in the guide groove 3336. At this time, the bottom of the abutment plate 3335 abuts against the unlocking lever 3324. The unlocking lever 3324 is pressed, driving the conversion lever 3322 to rotate. The rotation of the conversion lever 3322 causes the control spring 3325 to be compressed. When the conversion lever 3322 rotates until the tilt direction of the control block 3321 changes, the control spring 3325 resets, thereby causing the control block 3321 to drive the connecting ear 32 to disengage from the connecting seat 31, thus unlocking the connecting ear 32 and the connecting seat 31.

[0071] Simultaneously, the movement of the pressure rod 431 drives the abutment tooth 432 to abut against the positioning groove 423 of the switching gear 421, thereby driving the switching gear 421 to rotate 90 degrees. This 90-degree rotation of the switching gear 421 closes the light-shielding valve 41. This releases the locking of the connecting seat 31 and the connecting ear 32, while the light-shielding valve 41 blocks the laser channel of the connecting seat 31, thus preventing accidental laser emission. At this point, the different treatment heads 22 that need to be replaced can be removed.

[0072] Next, install the appropriate treatment head 22 on the mounting base 21, press the control ring 434 again, the control lever 3334 moves and drives the guide post 3332 to move, at the same time compressing the reset spring 3337. During the movement of the guide post 3332, the guide block 3333 moves synchronously in the guide groove 3336. At this time, the bottom of the abutment plate 3335 abuts against the locking lever 3323. The locking lever 3323 is pressed and drives the conversion lever 3322 to rotate. The rotation of the conversion lever 3322 causes the control spring 3325 to be compressed. When the conversion lever 3322 rotates to the point that the tilt direction of the control block 3321 changes, the control spring 3325 resets, which in turn causes the control block 3321 to drive the connecting ear 32 to abut against the connecting base 31, thereby completing the locking of the mounting base 21 and the treatment head 22.

[0073] Simultaneously, the movement of the pressure rod 431 drives the abutment tooth 432 to abut against the positioning groove 423 of the switching gear 421, thereby driving the switching gear 421 to rotate 90 degrees. This 90-degree rotation of the switching gear 421 opens the light-shielding valve 41. This locks the connecting seat 31 and the connecting ear 32, while the light-shielding valve 41 connects the laser channel of the connecting seat 31, allowing the treatment handpiece 2 to be used to treat the changed treatment area on the human body.

[0074] During the replacement of treatment head 22, pressing the control ring 434 simultaneously controls the connecting ear 32 to disengage from the connecting seat 31, while simultaneously closing the light-shielding valve 41 to prevent accidental laser emission; or simultaneously controls the connecting ear 32 to abut against the connecting seat 31, while simultaneously opening the light-shielding valve 41, allowing the laser to smoothly reach treatment head 22. This achieves the effect of rapid replacement of treatment head 22 without stopping the machine.

[0075] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
