[0025] Currently, a lesion can be treated by a laser treatment device. Taking a helium-neon laser as an example, a helium-neon laser is composed of components such as a laser discharge tube, a resonant cavity, and an excitation power supply. The laser discharge tube can emit laser light for treatment.

[0026] However, during the treatment process, the laser discharge tube of the laser treatment device often inevitably comes into contact with the target object. For example, when treating diseases such as rhinitis, chronic pharyngitis, and otitis membranacea, the laser discharge tube needs to enter the corresponding cavities, such as the nasal cavity, oral cavity, and ear canal. Therefore, the laser discharge tube needs to be repeatedly and thoroughly disinfected, resulting in low usage efficiency and high time cost.

[0027] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the laser treatment device provided by the present application.

[0028] To solve the above technical problems, the present application provides a laser treatment device 1, and the laser treatment device 1 includes a laser emission component 2. The laser treatment device 1 can be a laser or the like, and among them, the laser can be a helium-neon laser or the like. The laser emission component 2 can be used to emit a treatment beam 30. For example, the laser emission component 2 can emit lasers with different wavelengths for treating the target object. Optionally, the laser can have different wavelengths such as 632.8 nm, 1152 nm, 3391 nm, etc., and can be specifically set according to actual needs.

[0029] Refer to Figures 2 - 4 , Figure 2 which is a first schematic structural diagram of an embodiment of the laser emission component provided by the present application; Figure 3 is based on Figure 2 shown in the exploded view of an embodiment of the laser emission component; Figure 4 which is a second schematic structural diagram of an embodiment of the laser emission component provided by the present application.

[0030] The present application provides a laser emission component 2, and the laser emission component 2 includes: a laser discharge tube 10, which is arranged to extend along a first direction x1; an isolation sleeve 20, which is sleeved on one end of the laser discharge tube 10 along the first direction x1, and the isolation sleeve 20 is used to contact a target object; wherein, one end of the laser discharge tube 10 sleeved with the isolation sleeve 20 is used to emit a treatment beam 30, and the treatment beam 30 is transmitted through the isolation sleeve 20. The laser discharge tube 10 is one of the important components in a laser for generating laser. The laser discharge tube 10 is usually a closed tubular structure, filled with a laser medium (such as helium-neon gas) inside, and has two electrodes. When a high-voltage current passes through the laser discharge tube 10, the laser medium is excited to generate laser. The laser discharge tube 10 is arranged to extend along the first direction x1. It can be understood that the treatment beam 30 is emitted from one end of the laser discharge tube 10 sleeved with the isolation sleeve 20, and the treatment beam 30 can also be emitted along the first direction x1. The target object can be a target treatment organ, such as the ear, the oral cavity, etc. The treatment beam 30 is transmitted through the isolation sleeve 20. When it is necessary to make the treatment beam 30 accurately reach the target object, such as when it is necessary to accurately irradiate the eardrum with the treatment beam 30, the isolation sleeve 20 can be used to contact the ear canal, so that the laser discharge tube 10 is isolated from the target object such as the ear canal, thereby reducing the risk of contaminants such as germs that may exist on the target object from contaminating the laser discharge tube 10. Thus, when the laser discharge tube 10 emits the treatment beam 30, it does not need to directly contact the target object, reducing the risk of the laser discharge tube 10 being contaminated by the target object, thereby reducing the disinfection frequency of the laser discharge tube 10. When an operator, such as a medical worker, uses the laser discharge tube 10, it is not necessary to disinfect the laser discharge tube 10 every time, and only the isolation sleeve 20 needs to be replaced, thereby improving the convenience and use efficiency of the laser discharge tube 10, and further saving time costs.

[0031] In some embodiments, the isolation sleeve 20 is provided with a light-transmitting area 21, and the light-transmitting area 21 is located on the optical path of the treatment beam 30. The light-transmitting area 21 can be used to transmit the beam. Since the light-transmitting area 21 is located on the optical path of the treatment beam 30, the treatment beam 30 can pass through the light-transmitting area 21 and be transmitted from inside the isolation sleeve 20 to the outside. In some application scenarios, the isolation sleeve 20 can be at least partially made of a transparent material, such as plastics with good light transmittance, such as polyethylene (PE), polycarbonate (PC), polymethyl methacrylate (PMMA), polybutyl methacrylate (PMP), etc. In some other application scenarios, the isolation sleeve 20 can also be completely made of a transparent material, so that the entire isolation sleeve 20 is a light-transmitting area 21, making the transmission of the treatment beam 30 more sufficient and reducing the production cost of the isolation sleeve 20.

[0032] In some embodiments, the light-transmitting region 21 is a light-transmitting hole 22, and the treatment light beam 30 is transmitted through the light-transmitting hole 22. The light-transmitting region 21 can also be a light-transmitting hole 22. The light-transmitting hole 22 is disposed on the optical path of the treatment light beam 30, and the aperture of the light-transmitting hole 22 can be matched with the radius of the treatment light beam 30, so that the treatment light beam 30 can be transmitted from the light-transmitting hole 22 to the target object.

[0033] In some embodiments, the isolation sleeve 20 includes a cylindrical portion 23 and a bottom wall portion 24. The bottom wall portion 24 seals one end of the cylindrical portion 23. The cylindrical portion 23 is sleeved on the outer peripheral side of the laser discharge tube 10, and at least part of the light-transmitting region 21 is located on the bottom wall portion 24. The cylindrical portion 23 can be a cylindrical shape with both ends open. The bottom wall portion 24 seals one end of the cylindrical portion 23. The cylindrical portion 23 can be sleeved on the outer peripheral side of the laser discharge tube 10 through the open other end. The bottom wall portion 24 thus blocks one end of the laser discharge tube 10 that emits the treatment light beam 30, so that one end of the laser discharge tube 10 that emits the treatment light beam 30 is located in the accommodation space formed by the cylindrical portion 23 and the bottom wall portion 24. At least part of the light-transmitting region 21 is located on the bottom wall portion 24. Exemplarily, the light-transmitting region 21 can cover the entire bottom wall portion 24 or a part of the bottom wall portion 24, and can also cover at least part of the cylindrical portion 23. In some application scenarios, the bottom wall portion 24 is entirely made of a transparent material. After the treatment light beam 30 is emitted from one end of the laser discharge tube 10, it passes through the bottom wall portion 24 and is transmitted to the outside, and then the target object is treated.

[0034] In some embodiments, the inner side wall of the cylindrical portion 23 is attached to the outer side wall of the laser discharge tube 10 in a second direction x2 perpendicular to the first direction x1. Wherein, the first direction x1 can be the axial direction of the laser discharge tube 10, and the second direction x2 can be the radial direction of the laser discharge tube 10. The inner side wall of the cylindrical portion 23 is attached to the outer side wall of the laser discharge tube 10 in the second direction x2, so that the connection between the cylindrical portion 23 and the laser discharge tube 10 is more stable, reducing the risk of the isolation sleeve 20 detaching from the laser discharge tube 10, thereby improving the isolation effect of the isolation sleeve 20 on the laser discharge tube 10 and the target object.

[0035] In some embodiments, the laser discharge tube 10 is provided with a protruding portion 11 protruding from the outer wall of the laser discharge tube 10. The inner wall of the isolation sleeve 20 is provided with a mating portion 25, and the protruding portion 11 and the mating portion 25 are connected to each other. The protruding portion 11 can be any shape including but not limited to a triangle, a rectangle, a circle, etc. Exemplarily, when observed in the first direction x1, the protruding portion 11 can be annular and disposed around the circumferential side of the laser discharge tube 10. The inner wall of the isolation sleeve 20 is provided with a mating portion 25, and the shape of the mating portion 25 can match the shape of the protruding portion 11. Exemplarily, the mating portion 25 can have a clamping structure, so that the protruding portion 11 is clamped with the clamping structure. Or the mating portion 25 can have a hooking structure, so that the protruding portion 11 is hooked with the hooking structure. Thus, the connection and cooperation between the protruding portion 11 and the mating portion 25 can further improve the connection stability between the isolation sleeve 20 and the laser discharge tube 10, and reduce the risk of the isolation sleeve 20 detaching from the laser discharge tube 10.

[0036] In some embodiments, the mating portion 25 is a clamping groove 26, and the protruding portion 11 is clamped in the clamping groove 26. The shape of the clamping groove 26 can match the shape of the protruding portion 11, and the protruding portion 11 can be at least partially clamped in the clamping groove 26. Exemplarily, when the shape of the protruding portion 11 is circular, the shape of the clamping groove 26 can also be circular, so that the protruding portion 11 is more stably clamped in the clamping groove 26. In addition, the protruding portion 11 and the clamping groove 26 can be detachably connected.

[0037] In some embodiments, the protrusion 11 has a first surface 111 and a second surface 112 arranged in sequence along the first direction x1. The first surface 111 and the second surface 112 are respectively connected to the outer sidewall of the laser discharge tube 10. The first surface 111 is closer to the end of the laser discharge tube 10 where the isolation sleeve 20 is sleeved than the second surface 112, and the angle y between the first surface 111 and the first direction x1 is greater than 90 degrees. Exemplarily, when observed in a direction perpendicular to the outer sidewall of the laser discharge tube 10, the protrusion 11 can be triangular. One side surface of the triangle closer to the end where the laser discharge tube 10 emits the treatment beam 30 is the first surface 111, and the side surface away from the end where the laser discharge tube 10 emits the treatment beam 30 is the second surface 112, wherein the angle y between the first surface 111 and the first direction x1 is greater than 90 degrees. Thus, during the process of sleeving the isolation sleeve 20 onto the laser discharge tube 10, the first surface 111 can play a guiding role, facilitating the isolation sleeve 20 to be sleeved along the first direction x1 to the installation position under the guiding action of the first surface 111. It can be understood that at the installation position, the cooperation part 25 on the inner sidewall of the isolation sleeve 20 corresponds to and is connected to the protrusion 11 on the outer sidewall of the laser discharge tube 10. When the cooperation part 25 is a clamping groove 26, the protrusion 11 can be exactly clamped in the clamping groove 26 at the installation position. The first surface 111 can be directly connected to the second surface 112 or can be arranged at an interval from the second surface 112. Exemplarily, when the protrusion 11 is trapezoidal when observed in a direction perpendicular to the outer sidewall of the laser discharge tube 10, the first surface 111 and the second surface 112 can be respectively the two waists of the trapezoid.

[0038] In some embodiments, the number of the protrusions 11 and the cooperation parts 25 is multiple. The multiple protrusions 11 are arranged along the circumferential direction of the laser discharge tube 10 on the outer sidewall of the laser discharge tube 10, and the multiple cooperation parts 25 are arranged along the circumferential direction of the isolation sleeve 20 on the inner sidewall of the isolation sleeve 20. Each cooperation part 25 is correspondingly arranged with each protrusion 11. The multiple protrusions 11 can be arranged at intervals in sequence on the outer sidewall of the laser discharge tube 10 or can be arranged connected in sequence on the outer sidewall of the laser discharge tube 10. Each cooperation part 25 is correspondingly arranged with each protrusion 11. Thus, the multiple cooperation parts 25 and the multiple protrusions 11 correspond to each other one by one, thereby further improving the connection stability between the isolation sleeve 20 and the laser discharge tube 10, reducing the risk of the isolation sleeve 20 detaching from the laser discharge tube 10, and thus improving the isolation effect of the isolation sleeve 20 on the laser discharge tube 10 and the target object.

[0039] In summary, the present application provides a laser emission component 2, which includes: a laser discharge tube 10 extending along a first direction x1; an isolation sleeve 20 sleeved on one end of the laser discharge tube 10 along the first direction x1, and the isolation sleeve 20 is used to contact a target object; wherein, one end of the laser discharge tube 10 sleeved with the isolation sleeve 20 is used to emit a treatment beam 30, and the treatment beam 30 is transmitted through the isolation sleeve 20. Through the above implementation manner, the laser component extends along the first direction x1, the isolation sleeve 20 can be sleeved on one end of the laser discharge tube 10 for emitting the treatment beam 30 along the first direction x1, the laser emission component 2 can contact the target object through the isolation sleeve 20, and the treatment beam 30 can be emitted through the isolation sleeve 20. Thus, when the laser discharge tube 10 emits the treatment beam 30, it does not need to directly contact the target object, reducing the risk of the laser discharge tube 10 being contaminated by the target object, thereby reducing the disinfection frequency of the laser discharge tube 10, further improving the convenience and usage efficiency of the laser discharge tube 10, and saving time costs. Compared with other laser emission components, the laser emission component 2 provided by the present application has a higher usage efficiency and the laser discharge tube 10 requires a lower disinfection frequency.

[0040] The above are only the implementation manners of the present application, and do not limit the patent scope of the present application.
