In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0034] Next, according to the attached Figure 1 to the attached Figure 5 This utility model provides a laser is introduced. This laser can be used to generate a laser beam for medical treatment by means of the laser.

[0035] Specifically, this laser includes an outer shell 100, and at least n mounting positions and n - 1 beam combiners 3 (n is not less than 2) are provided inside the outer shell 100. Each mounting position is used to mount a modular resonator 1, and each modular resonator 1 can generate a laser beam. This laser has at least a first state and a second state, and can generate lasers with different intensities to meet different medical needs.

[0036] Exemplarily, when n is 2, in the first state, only one of the two mounting positions is mounted with a modular resonator 1. After the laser generated by this modular resonator 1 exits the outer shell 100, it has a lower intensity and can meet some relatively simple medical needs.

[0037] In the second state, the modular resonators 1 are installed in both of the two installation positions, and the two laser beams generated by the two modular resonators 1 can be combined by a beam combiner 3. After the combined laser beam exits the outer shell 100, it has medium intensity, high stability and consistency, and can be applied to medical applications such as fine cutting and coagulation hemostasis.

[0038] Of course, n can also be other values such as 3, 4, etc. Exemplarily, in some embodiments, n is 3, then the laser has a first state, a second state, and a third state. In the first state, the second state, and the third state, lasers with different intensities can be generated to meet different medical needs.

[0039] In the first state, only one of the three installation positions is installed with the modular resonator 1. After the laser beam generated by the modular resonator 1 exits the outer shell 100, it has low intensity and can meet some relatively simple medical needs.

[0040] In the second state, only two of the three installation positions are installed with the modular resonators 1, and the two laser beams generated by the two modular resonators 1 can be combined by a beam combiner 3. After the combined laser beam exits the outer shell 100, it has medium intensity, high stability and consistency, and can be applied to medical applications such as fine cutting and coagulation hemostasis.

[0041] In the third state, the modular resonators 1 are arranged in all three installation positions, and the three laser beams generated by the three modular resonators 1 can be combined by two beam combiners 3. After the laser beam generated by multiple beam combinations exits the outer shell 100, it has high intensity and concentration, and is particularly suitable for medical operations that require high energy density, such as deep tissue cutting or tumor ablation.

[0042] It should be noted that the modular resonators 1 have the same structure, and each modular resonator 1 can be installed in any one of the three installation positions. The beam combination process not only increases the intensity of the laser, but also has a positive impact on the performance of the laser. By precisely adjusting the phase and polarization state of each laser beam, the combined laser beam can maintain excellent directivity and beam quality, ensuring accuracy and safety in medical applications. In addition, the beam combination technology helps to reduce the divergence angle of the laser beam, making the laser energy more concentrated, thereby improving the treatment efficiency and reducing side effects.

[0043] In summary, the laser of the present utility model can achieve the output of laser that seemingly appears as a single beam but may actually be composed of multiple beams combined by flexibly configuring the modular resonator 1 and the beam combiner 3, and the laser intensity can be changed by switching different states. This design not only improves the flexibility and output power of the laser, but also optimizes the performance of the laser through the beam combining technology, providing a more efficient and safe treatment means for the medical field. At the same time, each modular resonator 1 has the same structure, with a high degree of part universality, which can significantly reduce the production cost and maintenance cost of the laser and improve its promotion and application value.

[0044] Specifically, as Figure 1 shown, in this embodiment, three mounting positions are arranged in the outer shell 100 along a preset first direction. Each mounting position is provided with four threaded holes and four insulating blocks 112, which can detachably and insulatively mount the modular resonator 1 on the mounting position. One reflector 2 is provided in the emission direction of each of two mounting positions, and two beam combiners 3 are provided in the emission direction of the other mounting position. Each reflector 2 can reflect a beam of laser towards a corresponding beam combiner 3, thereby achieving beam combination. Of course, the number of reflectors 2 should be the same as that of the beam combiners 3. Therefore, when there are n mounting positions, the number of reflectors 2 is also n - 1.

[0045] During specific use, when the laser emitted by a modular resonator 1 enters the reflector 2, it can be reflected by the reflector 2 towards a corresponding beam combiner 3, so as to be combined with the laser emitted by the modular resonator 1 on another mounting position through the beam combiner 3, making the laser intensity medium. Similarly, when the laser emitted by the remaining modular resonator 1 enters the reflector 2, it can be reflected by the reflector 2 towards another corresponding beam combiner 3, so as to be combined with the laser that has been beam combined once through the beam combiner 3 again, making the laser intensity high. Therefore, by controlling the number of modular resonators 1 set, the laser intensity can be controlled to meet different medical needs.

[0046] Of course, in some other embodiments, it is also possible to set modular resonators 1 on all three mounting positions, and by making one, two or three of the modular resonators 1 generate laser, the laser intensity can be adjusted by controlling different numbers of modular resonators 1.

[0047] Exemplarily, in the first state, only one of the three modular resonators 1 generates laser light. This laser light passes through the beam combiner 3 and then directly exits the outer shell 100, with a relatively low intensity. In the second state, only two of the three modular resonators 1 generate laser light. When the laser light emitted from one modular resonator 1 enters the mirror 2, it can be reflected by the mirror 2 towards the corresponding beam combiner 3, so as to be combined with the laser light emitted from the modular resonator 1 at another installation position through the beam combiner 3, making the intensity of the laser light medium. In the third state, laser light is generated in all three modular resonators 1. The three laser beams are combined into one beam by the mirror 2 and the beam combiner 3 and exit the outer shell 100, with a relatively high intensity.

[0048] Preferably, in this embodiment, among the three installation positions, two adjacent installation positions are arranged in a staggered manner along a preset second direction, and this preset second direction is perpendicular to the preset first direction. By arranging them in a staggered manner, the various pipeline interfaces provided on the modular resonator 1 can be staggered, facilitating disassembly and maintenance.

[0049] Specifically, as Figure 2 shown, in this embodiment, the modular resonator 1 includes a cover plate 102 and a housing 101. One side of the housing 101 is provided with an opening, and the cover plate 102 is detachably installed at the opening. A sealing ring 111 is provided between the cover plate 102 and the housing 101 to seal the housing 101. A window lens 108 is hermetically provided at one end of the housing 101, and the laser light can exit the modular resonator 1 through the window lens 108.

[0050] More specifically, as Figure 2 、 Figure 3 shown, the modular resonator 1 further includes a window mirror cover plate 109. The housing 101 is provided with an emission hole. The window lens 108 and the window mirror cover plate 109 are both provided at the emission hole. The window mirror cover plate 109 is hermetically connected to the housing 101 through a sealing ring 111 and bolts to seal the emission hole. The window lens 108 is fixedly installed on the window mirror cover plate 109 or clamped between the housing 101 and the window mirror cover plate 109. Of course, in some other embodiments, a window mirror cover plate 109 in the form of a threaded retaining ring can also be used, which also falls within the scope of protection of the present utility model.

[0051] As Figure 4 shown, a desiccant packet 104 is further provided inside the housing 101. The desiccant packet 104 can prevent the humidity inside the housing 101 from being too high. A condensing cavity 103 is provided inside the housing 101. The inner wall of the housing 101 has a recessed portion 1011. An accommodation space is formed between the recessed portion 1011 and the condensing cavity 103. The desiccant packet 104 is provided in the accommodation space to achieve a clamping and fixing effect through the condensing cavity 103 and the inner wall of the housing 101.

[0052] As Figures 3 to 5 shown, a reflecting lens, an adjusting bracket 105, a lamp wire 106 and a wire clamp 107 are further arranged in the housing 101. The condensing cavity 103 is fixedly arranged at the middle position of the bottom of the housing 101, and structures such as a pumping light source and a cooling system are arranged therein. The reflecting lens is installed on the adjusting bracket 105, and reflecting lenses and adjusting brackets 105 are arranged at both ends of the housing 101. The cooling system in the condensing cavity 103 is connected with a water pipe 113, and the water pipe 113 penetrates through the side surface of the housing 101 in a sealed manner to perform water cooling on the condensing cavity 103. A sealing ring 114 is arranged between the water pipe 113 and the housing 101 or they are connected through a through-board joint, which can achieve the effect of preventing leakage. The pumping light source in the condensing cavity 103 is connected with a lamp wire 106, and the lamp wire 106 penetrates through the housing 101 in a sealed manner through a rubber plug 110 to supply electric energy. The wire clamp 107 is arranged in the housing 101 and can play a role in fixing the lamp wire 106.

[0053] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
