[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The utility model discloses a laser blocking device, see Figure 1-4 , used to shield the laser window 2 of the medical laser device to prevent slight leakage of the laser beam during the laser preheating stage or the emission of the laser beam when the laser itself is uncontrollable.

[0038] Specifically, the laser blocking device includes a base 1, a transmission member 3, a shielding member 4 and a driving motor 5. The base 1 is arranged at the laser window 2. A slide groove 6 is provided on the base 1. The transmission member 3 is slidably arranged in the slide groove 6. The shielding member 4 is arranged on the side of the transmission member 3 close to the laser window 2 and is movably connected with the transmission member 3. The driving motor 5 is fixedly arranged on the base 1. The output end of the driving motor 5 is connected with the transmission member 3. During use, the driving motor 5 drives the transmission member 3 to make the shielding member 4 move toward the laser window 2, thereby shielding the laser window 2. At this time, the laser window 2 is shielded by the shielding member 4, which can effectively avoid slight laser beam leakage during the laser preheating stage or the emission of laser beam when the laser itself is uncontrollable.

[0039] In this embodiment, the transmission member 3 includes a rack 31 and a gear 32. The rack 31 is slidably set in the slide groove 6. The shielding member 4 is set at one end of the rack 31 close to the laser window 2. The gear 32 is set at the output end of the driving motor 5 and meshes with the rack 31. During use, the output end of the driving motor 5 drives the rack 31 to move along the slide groove 6 through the gear 32, thereby driving the shielding member 4 to move toward the laser window 2, thereby shielding the laser window 2 to prevent slight laser beam leakage during the laser preheating stage or the emission of a laser beam when the laser itself is uncontrollable.

[0040] In this embodiment, the output end of the drive motor 5 is a polygonal or special-shaped structure, and the gear 32 is provided with a groove adapted to the output end of the drive motor 5. During use, the gear 32 is clamped on the output end of the drive motor 5 through the groove, and the drive motor 5 drives the gear 32 to rotate through the output end of the polygonal or special-shaped structure.

[0041] In the field of medical lasers, medical laser devices are generally designed to be very small for the convenience of hand-holding or use, which also requires the maximum use of the space in the medical laser device. In this embodiment, the gear 32 is a quarter gear 32, so that the drive motor 5 can drive the transmission member 3 to move, while greatly increasing the utilization rate of the space in the medical laser device. More preferably, when the drive device drives the shielding member 4 to shield the laser window 2, the end of the rack 31 connected to the shielding member 4 is suspended in the air. However, in this laser shielding device, the rack 31 is directly placed in the slide groove 6. Therefore, once the laser blocking device shakes, this may cause the rack 31 to detach from the slide groove 6. Therefore, in order to ensure that the rack 31 can be stably fixed in the slide groove 6, in this embodiment, the gear 32 and the rack 31 need to always keep meshing, that is, the gear 32 needs to always abut the rack 31, thereby ensuring the stability of the rack 31 during use.

[0042] In this embodiment, a receiving member is provided at one end of the rack 31 close to the laser window 2, and the shielding member 4 is arranged on the receiving member by bolts. Specifically, in this embodiment, the shielding member is made of high-temperature resistant phlogopite mica sheets, which have good high-temperature resistance and can withstand a maximum temperature of 1000 degrees Celsius, effectively blocking the strong beam of the laser.

[0043] In this embodiment, a receiving groove 7 for receiving the shielding member 4 is further provided on the side of the base 1 close to the laser window 2. When the medical laser equipment is in normal use, the shielding member 4 needs to be moved out of the laser window 2. Therefore, when the driving motor 5 drives the rack 31 to move away from the laser window 2, the shielding member 4 can be received in the receiving groove 7, thereby making the laser window 2 unobstructed.

[0044] In this embodiment, a travel opening for controlling the travel of the shielding member 4 is also provided on the base 1. The travel switch 8 is electrically connected to the drive motor 5. The travel switch 8 is respectively arranged at both ends of the slide groove 6. During use, when the shielding member 4 blocks the laser window 2 or is located in the storage groove 7, the rack 31 triggers the travel switch 8. At this time, the travel switch 8 sends an in-position instruction to the drive motor 5. After receiving the in-position instruction, the drive motor 5 stops rotating, thereby preventing the gear 32 from disengaging from the rack 31 due to excessive rotation.

[0045] Specifically, the travel switch 8 includes a push switch 9 and a spring 10. The button of the push switch 9 is arranged toward the slide groove 6. The side of the push switch 9 where the button is provided is also provided with a spring 10. When the shielding member 4 blocks the laser window 2 or is located in the storage groove 7, the rack 31 resists the spring 10, causing the spring 10 to undergo elastic deformation and thus trigger the button. In this process, the spring 10 has a buffering effect on the button of the push switch 9, thereby greatly increasing the service life of the push switch 9.

[0046] The utility model also discloses a medical laser device provided with a laser blocking device, comprising a laser nozzle, and a laser window 2 provided with any one of the above-mentioned laser blocking devices.

[0047] Specifically, the laser blocking device includes a base 1, a transmission member 3, a shielding member 4 and a driving motor 5. The base 1 is arranged at the laser window 2. A slide groove 6 is provided on the base 1. The transmission member 3 is slidably arranged in the slide groove 6. The shielding member 4 is arranged on the side of the transmission member 3 close to the laser window 2 and is movably connected with the transmission member 3. The driving motor 5 is fixedly arranged on the base 1. The output end of the driving motor 5 is connected with the transmission member 3. During use, the driving motor 5 drives the transmission member 3 to make the shielding member 4 move toward the laser window 2, thereby shielding the laser window 2. At this time, the laser window 2 is shielded by the shielding member 4, which can effectively avoid slight laser beam leakage during the laser preheating stage or the emission of laser beam when the laser itself is uncontrollable.

[0048] In this embodiment, the transmission member 3 includes a rack 31 and a gear 32. The rack 31 is slidably set in the slide groove 6. The shielding member 4 is set at one end of the rack 31 close to the laser window 2. The gear 32 is set at the output end of the driving motor 5 and meshes with the rack 31. During use, the output end of the driving motor 5 drives the rack 31 to move along the slide groove 6 through the gear 32, thereby driving the shielding member 4 to move toward the laser window 2, thereby shielding the laser window 2 to prevent slight laser beam leakage during the laser preheating stage or the emission of a laser beam when the laser itself is uncontrollable.

[0049] In this embodiment, the output end of the drive motor 5 is a polygonal or special-shaped structure, and the gear 32 is provided with a groove adapted to the output end of the drive motor 5. During use, the gear 32 is clamped on the output end of the drive motor 5 through the groove, and the drive motor 5 drives the gear 32 to rotate through the output end of the polygonal or special-shaped structure.

[0050] In the field of medical lasers, medical laser devices are generally designed to be very small for the convenience of hand-holding or use, which also requires the maximum use of the space in the medical laser device. In this embodiment, the gear 32 is a quarter gear 32, so that the drive motor 5 can drive the transmission member 3 to move, while greatly increasing the utilization rate of the space in the medical laser device. More preferably, when the drive device drives the shielding member 4 to shield the laser window 2, the end of the rack 31 connected to the shielding member 4 is suspended in the air. However, in this laser shielding device, the rack 31 is directly placed in the slide groove 6. Therefore, once the laser blocking device shakes, this may cause the rack 31 to detach from the slide groove 6. Therefore, in order to ensure that the rack 31 can be stably fixed in the slide groove 6, in this embodiment, the gear 32 and the rack 31 need to always keep meshing, that is, the gear 32 needs to always abut the rack 31, thereby ensuring the stability of the rack 31 during use.

[0051] In this embodiment, a receiving member is provided at one end of the rack 31 close to the laser window 2, and the shielding member 4 is arranged on the receiving member by means of bolts.

[0052] In this embodiment, a receiving groove 7 for receiving the shielding member 4 is further provided on the side of the base 1 close to the laser window 2.

Therefore, when the driving motor 5 drives the rack 31 to move away from the laser window 2, the shielding member 4 can be received in the receiving groove 7, thereby making the laser window 2 unobstructed.
