Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a laser synthesis device. Background Technology

[0002] Laser technology is widely used in the field of medical devices. Due to its high precision and low invasiveness, it is often used in surgical procedures such as stone fragmentation, soft tissue vaporization, resection, removal, and hemostasis.

[0003] In existing technologies, medical surgeries typically use single-wavelength lasers as the light source, such as in the fragmentation of urinary stones or the treatment of benign prostatic hyperplasia. A single-wavelength laser is transmitted to the surgical site via optical fiber for specific tissue treatment. However, the effectiveness of single-wavelength lasers is relatively limited. The interaction of a single-wavelength laser with biological tissue has limitations, making it difficult to simultaneously meet multiple clinical needs. For example, it cannot effectively stop bleeding after the explosive cutting of biological tissue, resulting in low surgical treatment efficiency. Utility Model Content

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] Figure 1 This is a schematic diagram of the structure of a laser synthesis device provided in an embodiment of this utility model. Figure 1 As shown, the laser combining device includes a first laser generator 1, a second laser generator 2, a third laser generator 3, a laser beam combiner 4, a laser transmitter 5, and a laser beam combiner driver 6; the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3 have different wavelengths; the first laser generator 1, the second laser generator 2, and the third laser generator 3 are located on at least one side of the laser beam combiner 4; the laser transmitter 5 is located on the light-emitting side 41 of the laser beam combiner 4; the laser beam combiner driver 6 is connected to the laser beam combiner 4; the laser beam combiner driver 6 drives the laser beam combiner 4 to move, and the laser beam combiner 4 selectively emits at least one of the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3.

[0021] Specifically, the first laser generator 1, the second laser generator 2, and the third laser generator 3 can be understood as light source devices that generate laser beams of specific wavelengths, and the wavelengths of the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3 are different. For example, the first laser generator 1 can be a solid-state laser used to generate a laser beam with a wavelength of 2100nm; the second laser generator 2 can be a fiber laser used to generate a laser beam with a wavelength of 1940nm; and the third laser generator 3 can be a semiconductor laser used to generate a laser beam with a wavelength of 980nm. Understandably, laser beams with a wavelength of 2100nm have strong absorption of water and soft tissue, making them suitable for explosive cutting of biological tissues and lithotripsy. The high peak power of a 2100nm laser beam can generate shock waves, efficiently breaking up hard tissues. Laser beams with a wavelength of 1940nm have strong absorption of water and soft tissue, making them suitable for fine cutting and soft tissue vaporization. The thermal effect of a 1940nm laser beam is moderate, reducing trauma. Laser beams with a wavelength of 980nm have strong absorption of hemoglobin, making them suitable for low-power continuous wave output, and they are highly effective in surgical wound management or vascular closure.

[0022] The first laser generator 1, the second laser generator 2, and the third laser generator 3 are located on at least one side of the laser beam combiner 4, so that the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3 can all be transmitted to the laser beam combiner 4. This allows the laser beam combiner 4 to combine laser beams of multiple wavelengths generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3 as needed. For example, the laser beam combiner 4 may include a mirror or a group of mirrors provided with specific transmission and reflection films. This allows the laser beam combiner 4 to selectively emit at least one of the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3 to the laser transmitter 5 by adjusting the motion state of the laser beam combiner 4, such as by controlling the rotation or linear movement of the laser beam combiner 4, thereby achieving the combination of laser beams of multiple wavelengths.

[0023] The laser beam combiner driver 6 may specifically include a mechanical device, such as a motor or a cam structure. Specifically, the laser beam combiner driver 6 and the laser beam combiner 4 can be mechanically connected, for example, by a shaft connection, so that the laser beam combiner driver 6 can drive the laser beam combiner 4 to move, such as driving the laser beam combiner 4 to rotate or move linearly, so as to adjust the angle or position of the input and output sides of the laser beam combiner 4, thereby enabling the laser beam combiner 4 to selectively output laser beams of different wavelengths to the laser transmitter 5 using specific transmission and reflection films. Understandably, when only one of the first laser generator 1, the second laser generator 2, and the third laser generator 3 generates a laser beam, the laser beam combiner 4 can be driven to move by controlling the laser beam combiner driver 6 to switch the wavelength of the laser beam output to the laser transmitter 5 as needed. This is suitable for application scenarios that require treatment with a single wavelength. When two or three of the first laser generator 1, the second laser generator 2, and the third laser generator 3 generate laser beams simultaneously, the laser beam combiner 4 can be driven to move by controlling the laser beam combiner driver 6 to transmit multiple wavelengths of laser beams to the laser transmitter 5 simultaneously. This enables the beam combining and output of multiple wavelengths of laser beams, which is suitable for scenarios that require multifunctional treatment.

[0024] The laser transmitter 5 is located on the light-emitting side 41 of the laser combiner 4. For example, the laser transmitter 5 may include an optical fiber coupler and a medical laser fiber, so that the laser transmitter 5 can receive the laser beam emitted after being combined by the laser combiner 4, and can couple the combined laser beam to the medical laser fiber through the optical fiber coupler for transmission, thereby ensuring that the laser beam can be accurately delivered to the surgical site.

[0025] It is also understandable that when only one of the first laser generator 1, the second laser generator 2, and the third laser generator 3 generates a laser beam, the laser beam combiner 4 can be driven to move by controlling the laser beam combiner driver 6 to switch the wavelength of the laser beam output to the laser transmitter 5 as needed. This allows the laser transmitter 5 to deliver a single wavelength laser beam to the surgical site, suitable for applications requiring treatment with a single wavelength. For example, the laser transmitter 5 can deliver a 2100nm laser beam to the surgical site for cutting biological tissue, or it can deliver a 980nm laser beam to the surgical site for hemostasis. When two or three of the first laser generator 1, the second laser generator 2, and the third laser generator 3 generate a laser beam... When laser beams are generated simultaneously, the laser beam combiner 4 can be driven to move by the laser beam combiner driver 6, enabling the simultaneous transmission of multiple wavelengths of laser beams to the laser transmitter 5. This allows the laser transmitter 5 to simultaneously deliver multiple wavelengths of laser beams to the surgical site, suitable for scenarios requiring multi-functional treatment. For example, the laser transmitter 5 can simultaneously deliver laser beams with wavelengths of 2100nm, 1940nm, and 980nm to the surgical site, achieving multiple functions simultaneously, such as tissue cutting with the 2100nm laser beam, hemostasis with the 980nm laser beam, and vaporization assistance with the 1940nm laser beam. This can simultaneously meet various clinical needs and improve surgical efficiency. Furthermore, the design of using the laser beam combiner driver 6 to drive the laser beam combiner 4 simplifies the structure of the laser combining device, avoiding the complex layout of multiple fixed lenses for laser beam combining, thereby reducing the manufacturing and maintenance costs of the laser combining device.

[0026] In this embodiment, a laser combining device is configured with a first laser generator, a second laser generator, a third laser generator, a laser beam combiner, a laser transmitter, and a laser beam combiner driver. By setting the wavelengths of the laser beams generated by the first, second, and third laser generators to be different, the therapeutic characteristics of different wavelength laser beams can be utilized to meet various clinical needs. By placing the first, second, and third laser generators on at least one side of the laser beam combiner, the laser beams generated by all three generators can be transmitted to the laser beam combiner. By placing the laser transmitter on the output side of the laser beam combiner and connecting it to the laser beam combiner, the laser beam combiner driver can drive the laser beam combiner to move, for example, by rotating or linearly moving it. This allows adjustment of the angle or position of the input and output sides of the laser beam combiner, enabling the laser beam combiner to selectively output at least one of the laser beams generated by the first, second, and third laser generators to the laser transmitter. This enables the laser transmitter to simultaneously transmit multiple wavelengths of laser beams to the surgical site after receiving them from the laser beam combiner. This is suitable for scenarios requiring multifunctional treatment, such as simultaneously performing multiple functions like tissue cutting, hemostasis, and assisted vaporization. This allows for the simultaneous fulfillment of various clinical needs, improves surgical treatment efficiency, and reduces the manufacturing and maintenance costs of the laser synthesis device.

[0027] Figure 2 This is a schematic diagram of another laser synthesis device provided in an embodiment of this utility model. Figure 2 As shown, the laser transmitter 5 includes an optical fiber coupler 51 and a laser fiber 52; the optical fiber coupler 51 is disposed on the output side 41 of the laser beam combiner 4, and the optical fiber coupler 51 includes a laser input end 511 and a laser output end 512; the laser input end 511 faces the output side 41 of the laser beam combiner 4; the laser output end 512 is connected to the laser fiber 52; the laser beam from the output side 41 of the laser beam combiner 4 is coupled to the laser fiber 52 via the optical fiber coupler 51.

[0028] Specifically, fiber optic coupler 51 is disposed on the output side 41 of laser beam combiner 4, with its laser input end 511 facing the output side 41 of laser beam combiner 4, so that fiber optic coupler 51 can receive the laser beam emitted after being combined by laser beam combiner 4 through its laser input end 511. Fiber optic coupler 51 can also adjust the incident angle and mode of the laser beam through its internal lens or optical path design, thereby directly matching the laser beam from the output side 41 of laser beam combiner 4 with the core of laser fiber 52. Simultaneously, the laser output end 512 of fiber optic coupler 51 is connected to laser fiber 52, so that fiber optic coupler 51 can also couple the laser beam from the output side 41 of laser beam combiner 4 to laser fiber 52 through its laser output end 512.

[0029] The laser fiber 52 can specifically include medical-grade quartz or polymer fiber, possessing high light transmittance and flexibility to transmit high-power laser beams. After receiving the laser beam coupled by the fiber coupler 51, the laser fiber 52 can be combined with an endoscope or surgical instruments to precisely transmit the laser beam to the target tissue via total internal reflection, suitable for complex surgical procedures. Transmitting the laser beam from the output side 41 of the laser combiner 4 through the fiber coupler 51 and the laser fiber 52 reduces light energy loss, improves the energy utilization rate of the laser combining device, and simultaneously meets multiple clinical needs, thereby enhancing surgical treatment efficiency.

[0030] Optional, continue to refer to Figure 2 The laser combining device also includes a controller 7; the controller 7 includes a laser beam combining control terminal 71; the laser beam combining control terminal 71 is connected to the control terminal 61 of the laser beam combining driver 6.

[0031] The controller 7 may include a microprocessor, such as a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof. Specifically, the laser beam combining control terminal 71 of the controller 7 is connected to the control terminal 61 of the laser beam combining driver 6, so that the controller 7 can send control signals to the laser beam combining driver 6 through the laser beam combining controller 71. This allows the laser beam combining driver 6 to drive the laser beam combiner 4 to move according to the control signals, such as driving the laser beam combiner 4 to rotate or move linearly, so as to adjust the angle or position of the input and output sides of the laser beam combiner 4. This allows the laser beam combiner 4 to selectively output laser beams of different wavelengths to the laser transmitter 5 using specific transmission and reflection films. The controller 7 drives the laser beam combiner 6 through the laser beam combiner control terminal 71, so as to precisely adjust the motion state of the laser beam combiner 4 according to the needs of the surgery. This enables the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3 to be output to the laser transmitter 5 respectively, or the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3 to be transmitted to the laser transmitter 5 simultaneously. This can meet multiple clinical needs at the same time and improve the efficiency of surgical treatment.

[0032] Optional, continue to refer to Figure 2 The controller 7 also includes a first laser generation control terminal 72, a second laser generation control terminal 73, and a third laser generation control terminal 74; the first laser generation control terminal 72 is connected to the control terminal 11 of the first laser generator 1; the second laser generation control terminal 73 is connected to the control terminal 21 of the second laser generator 2; and the third laser generation control terminal 74 is connected to the control terminal 31 of the third laser generator 3.

[0033] Specifically, the first laser generation control terminal 72 of the controller 7 is connected to the control terminal 11 of the first laser generator 1, so that the controller 7 can send a control signal to the first laser generator 1 through the first laser generation control terminal 72, thereby controlling whether the first laser generator 1 generates a laser beam; the second laser generation control terminal 73 of the controller 7 is connected to the control terminal 21 of the second laser generator 2, so that the controller 7 can send a control signal to the second laser generator 2 through the second laser generation control terminal 73, thereby controlling whether the second laser generator 2 generates a laser beam; the third laser generation control terminal 73 of the controller 7 is connected to the control terminal 31 of the third laser generator 3, so that the controller 7 can send a control signal to the third laser generator 3 through the third laser generation control terminal 73, thereby controlling whether the third laser generator 3 generates a laser beam. The controller 7 controls whether the first laser generator 1, the second laser generator 2, and the third laser generator 3 generate laser beams through the first laser generation control terminal 72, the second laser generation control terminal 73, and the third laser generation control terminal 74, respectively. This allows the laser synthesis device to activate the laser generator capable of generating laser beams of specific wavelengths as needed according to the surgical requirements, thereby avoiding unnecessary operation of the laser generators, reducing energy consumption and thermal effects, and improving the efficiency of surgical treatment.

[0034] Optional, continue to refer to Figure 2 The laser synthesis device also includes a control module 8 and a display module 9; the controller 7 also includes a control signal input terminal 75 and a display signal output terminal 76; the control module 8 is connected to the control signal input terminal 75; and the display signal output terminal 76 is connected to the display module 9.

[0035] The control module 8 may include physical buttons, physical knobs, or a touch screen. The control module 8 is connected to the control signal input terminal 75 so that the operator can input control commands, such as the wavelength of the laser beam to be combined, into the controller 7 through the control module 8. This allows the controller 7 to drive the driver 6 to adjust the movement state of the laser beam combiner 4 as needed according to the control commands, and to control the opening or closing of the first laser generator 1, the second laser generator 2, and the third laser generator 3 according to the control commands. For example, when surgery requires simultaneous cutting and hemostasis, the surgeon can input control commands to the controller 7 through the control module 8. After receiving the control commands, the controller 7 can control the first laser generator 1 and the third laser generator 3 to generate laser beams through the first laser generation control terminal 72 and the third laser generation control terminal 74, respectively. It can also drive the laser beam combiner 6 through the laser beam combiner control terminal 71 to adjust the laser beam combiner 4 to a preset state, so that the laser beam combiner 4 can selectively output the laser beams generated by the first laser generator 1 and the third laser generator 3 to the laser transmitter 5. This achieves the simultaneous transmission of the 2100nm wavelength laser beam generated by the first laser generator 1 and the 980nm wavelength laser beam generated by the third laser generator 3 to the surgical site, so as to realize the synchronous performance of cutting and hemostasis, thereby meeting multiple clinical needs and improving the efficiency of surgical treatment.

[0036] The display module 9 may specifically include a liquid crystal display (LCD), an organic light-emitting diode (OLED) screen, or LED indicator lights. The display module 9 is connected to the display signal output terminal 76 of the controller 7, enabling it to receive real-time operating data of the laser synthesis device sent by the controller 7 through the display signal output terminal 76. This data includes, for example, the real-time operating status of the first laser generator 1, the second laser generator 2, and the third laser generator 3. The display module 9 can present this data to the surgeon in text, graphic, or indicator light format, thereby helping the surgeon monitor and verify whether the control commands are effectively executed. For example, when surgery requires simultaneous cutting and hemostasis, the display module 9 can show that the first laser generator 1 is on, the second laser generator 2 is off, and the third laser generator 3 is on, allowing the surgeon to confirm the wavelength of the laser beam currently delivered to the surgical site and adjust the control commands accordingly.

[0037] By incorporating a control module 8 and a display module 9, surgeons can intuitively select the required laser beam wavelength according to surgical needs and promptly understand the working status of each laser generator in the laser synthesis device, thus improving operational convenience and surgical safety. Simultaneously, this allows the laser synthesis device to adapt to diverse surgical requirements, improving surgical efficiency and precision.

[0038] Optional, continue to refer to Figure 2The laser beam combiner 4 includes a beam combiner mirror 42; a first laser generator 1, a second laser generator 2, a third laser generator 3 and a laser transmitter 5 are arranged around the beam combiner mirror 42; a laser beam combiner driver 6 is connected to the beam combiner mirror 42; and the laser beam combiner driver 6 drives the beam combiner mirror 42 to rotate.

[0039] The beam combiner mirror 42 may include an incident surface and an exit surface, both of which may be provided with specific transmission and reflection films. Specifically, the beam combiner mirror 42 is used to adjust the transmission optical path of the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3. Specifically, the first laser generator 1, the second laser generator 2, the third laser generator 3, and the laser transmitter 5 are arranged around the beam combiner mirror 42 so that the incident angles of the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3 are uniformly distributed relative to the beam combiner mirror 42. Simultaneously, the laser beam combiner driver 6 is connected to the beam combiner mirror 42, enabling the laser beam combiner driver 6 to drive the beam combiner mirror 42 to rotate. This allows the laser beam combiner driver 6 to drive the beam combiner mirror 42 to rotate around its axis, changing the angles of the incident and exit surfaces of the beam combiner mirror 42. This adjusts the reflection or transmission paths of the laser beams generated by the first laser generator 1, the second laser generator 2, and the third laser generator 3. Consequently, the beam combiner mirror 42 can selectively output laser beams of different wavelengths to the laser transmitter 5 using specific transmission and reflection films. This simultaneously meets multiple clinical needs, improves surgical treatment efficiency, and avoids the complex layout of laser beam combining using multiple fixed lenses, reducing the manufacturing and maintenance costs of the laser combining device.

[0040] Optional, continue to refer to Figure 2 A first laser generator 1 generates a laser beam of a first wavelength; a second laser generator 2 generates a laser beam of a second wavelength; a third laser generator 3 generates a laser beam of a third wavelength; a beam combiner mirror 42 includes an incident light surface 421 and an exit light surface 422; the incident light surface 421 is provided with a first transmission film; the exit light surface 422 is provided with a second transmission film, a first reflection film, and a second reflection film; the first transmission film transmits the laser beam of the third wavelength and blocks the laser beam of the first wavelength and the laser beam of the second wavelength; the second transmission film transmits the laser beam of the third wavelength and blocks the laser beam of the first wavelength and the laser beam of the second wavelength; the first reflection film reflects the laser beam of the first wavelength; the second reflection film reflects the laser beam of the second wavelength.

[0041] Specifically, the first wavelength can be 2100nm, the second wavelength can be 1940nm, and the third wavelength can be 980nm. Specifically, the incident surface 421 of the beam combiner mirror 42 is provided with a first transmission film, which transmits the third wavelength laser beam and blocks the first and second wavelength laser beams. The emitting surface 422 of the beam combiner mirror 42 is provided with a second transmission film, a first reflection film, and a second reflection film. The second transmission film transmits the third wavelength laser beam and blocks the first and second wavelength laser beams, while the first and second reflection films reflect the first wavelength laser beam and the second reflection film reflects the second wavelength laser beam. This allows the beam combiner mirror 42 to transmit or reflect the first, second, and third wavelength laser beams when the incident surface 421 and the emitting surface 422 are at a specific angle, thereby adjusting the wavelength of the laser beam output from the beam combiner mirror 42 to the laser transmitter 5.

[0042] In one exemplary embodiment, such as Figure 2 As shown, the laser beam combiner 6 can drive the beam combiner mirror 42 to rotate to a first preset position. When the beam combiner mirror 42 rotates to the first preset position, the first wavelength laser beam and the third wavelength laser beam are incident on the incident surface 421, and the second wavelength laser beam is incident on the exit surface 422. This prevents the first wavelength laser beam from entering the beam combiner mirror 42 due to being blocked by the incident surface 421. The third wavelength laser beam is transmitted through the incident surface 421 and the exit surface 422 in sequence and then exits to the laser transmitter 5. The second wavelength laser beam is reflected by the exit surface 422 and then exits to the laser transmitter 5. This achieves the beam combiner mirror 42 to combine the second and third wavelength laser beams into the laser transmitter 5 by driving the beam combiner mirror 42 to rotate, enabling the laser transmitter 5 to simultaneously transmit the second and third wavelength laser beams to the surgical site, thus achieving simultaneous precision cutting and hemostasis.

[0043] In another exemplary embodiment, such as Figure 3As shown, the laser beam combiner 6 can drive the beam combiner mirror 42 to rotate to a second preset position. When the beam combiner mirror 42 rotates to the second preset position, the second wavelength laser beam and the third wavelength laser beam are incident on the incident surface 421, and the first wavelength laser beam is incident on the exit surface 422. This causes the second wavelength laser beam to be blocked by the incident surface 421 and unable to enter the beam combiner mirror 42. The third wavelength laser beam is transmitted sequentially through the incident surface 421 and the exit surface 422 and then exits to the laser transmitter 5. The first wavelength laser beam is reflected by the exit surface 422 and then exits to the laser transmitter 5. This achieves the beam combiner mirror 42 driven by the laser beam combiner 6 to combine the first wavelength laser beam and the third wavelength laser beam into the laser transmitter 5, enabling the laser transmitter 5 to simultaneously transmit the first wavelength laser beam and the third wavelength laser beam to the surgical site, thus achieving simultaneous explosive cutting and hemostasis.

[0044] In another exemplary embodiment, such as Figure 4 As shown, the laser beam combiner driver 6 can drive the beam combiner mirror 42 to rotate to a third preset position. When the beam combiner mirror 42 rotates to the third preset position, the first wavelength laser beam and the second wavelength laser beam cannot be incident on the light-incident surface 421 or the light-outcident surface 422 of the beam combiner mirror 42, while the third wavelength laser beam is incident on the light-incident surface 421. This allows the third wavelength laser beam to be transmitted to the laser transmitter 5 after being transmitted through the light-incident surface 421 and the light-outcident surface 422 in sequence. This achieves the transmission of the third wavelength laser beam to the laser transmitter 5 by driving the beam combiner mirror 42 to rotate via the laser beam combiner driver 6, enabling the laser transmitter 5 to transmit the third wavelength laser beam to the surgical site. This is suitable for treatment scenarios requiring only hemostasis. At this time, the first laser generator 1 and the second laser generator 2 can be turned off to reduce energy consumption and thermal effects.

[0045] Optional, Figure 5 This is a schematic diagram of another laser synthesis device provided in an embodiment of this utility model. Figure 5 As shown, the laser beam combiner 4 includes a first reflector 43, a second reflector 44, and a semi-reflective mirror 45; the first reflector 43, the second reflector 44, and the semi-reflective mirror 45 are arranged sequentially along a first direction; a first laser generator 1 is disposed on the reflecting surface 431 side of the first reflector 43; a second laser generator 2 is disposed on the reflecting surface 441 side of the second reflector 44; a third laser generator 3 is disposed on the reflecting surface 451 side of the semi-reflective mirror 45; a laser beam combiner driver 6 is connected to the second reflector 44; the laser beam combiner driver 6 drives the second reflector 44 to move along a second direction; the first direction and the second direction intersect.

[0046] Specifically, the first reflector 43 includes a reflective surface 431, which may be provided with a specific reflective film. A first laser generator 1 is disposed on the reflective surface 431 side of the first reflector 43, enabling the first reflector 43 to adjust the transmission path of the laser beam generated by the first laser generator 1. The second reflector 44 includes a reflective surface 441, which may be provided with a specific reflective film. A second laser generator 2 is disposed on the reflective surface 441 side of the second reflector 44, enabling the second reflector 44 to adjust the transmission path of the laser beam generated by the second laser generator 2. The semi-reflective mirror 45 includes a reflective surface 451 and a transparent surface 452. A third laser generator 3 is disposed on the reflective surface 451 side of the semi-reflective mirror 45, enabling the semi-reflective mirror 45 to adjust the transmission path of the laser beam generated by the third laser generator 3. Meanwhile, the first reflector 43, the second reflector 44, and the semi-reflective mirror 45 are arranged sequentially along a first direction, which can be, for example, a vertical direction, thereby forming a linear optical path structure. The laser transmitter 5 is located at the end of the optical path. The laser beam combiner 6 is connected to the second reflector 44 so that the laser beam combiner 6 can drive the second reflector 44 to move along a second direction, which can be, for example, a horizontal direction. This allows the laser beam combiner 6 to drive the second reflector 44 to move into or out of the linear optical path, thereby adjusting the reflection or transmission path of the laser beams generated by the first laser generator 1 and the second laser generator 2. As a result, the laser beam combiner 4 can selectively output laser beams of different wavelengths to the laser transmitter 5 using either the linear optical path formed by the first reflector 43 and the semi-reflective mirror 45 or the linear optical path formed by the second reflector 44 and the semi-reflective mirror 45. This can simultaneously meet multiple clinical needs, improve surgical treatment efficiency, and avoid the complex layout of laser beam combining through multiple fixed lenses, thus reducing the manufacturing and maintenance costs of the laser combining device.

[0047] Optional, continue to refer to Figure 5A first laser generator 1 generates a laser beam of a first wavelength; a second laser generator 2 generates a laser beam of a second wavelength; a third laser generator 3 generates a laser beam of a third wavelength; a third reflective film is provided on the reflective surface 431 of the first reflector 43; the third reflective film reflects the laser beam of the first wavelength; a fourth reflective film is provided on the reflective surface 441 of the second reflector 44; the fourth reflective film reflects the laser beam of the second wavelength; a semi-reflective mirror 45 includes opposing reflective surfaces 451 and a light-transmitting surface 452; the light-transmitting surface 452 of the semi-reflective mirror 45 is provided with a third transmission film and a fourth transmission film; the semi-reflective mirror 45... The reflective surface 451 is provided with a fifth reflective film, a fifth transmissive film, and a sixth transmissive film; the third transmissive film transmits a laser beam of the first wavelength and blocks laser beams of the second and third wavelengths; the fourth transmissive film transmits a laser beam of the second wavelength and blocks laser beams of the first and third wavelengths; the fifth reflective film reflects a laser beam of the third wavelength; the fifth transmissive film transmits a laser beam of the first wavelength and blocks laser beams of the second and third wavelengths; the sixth transmissive film transmits a laser beam of the second wavelength and blocks laser beams of the first and third wavelengths.

[0048] Specifically, the first wavelength can be 2100nm, the second wavelength can be 1940nm, and the third wavelength can be 980nm. Specifically, the first reflector 433 has a third reflective film on its reflective surface 431, which reflects the laser beam of the first wavelength. The second reflector 444 has a fourth reflective film on its reflective surface 441, which reflects the laser beam of the second wavelength. The semi-reflective mirror 45 includes a reflecting surface 451 and a transmitting surface 452. The reflecting surface 451 is provided with a third transmission film and a fourth transmission film, and the transmitting surface 452 is provided with a fifth reflecting film, a fifth transmission film, and a sixth transmission film. The third transmission film transmits a laser beam of the first wavelength and blocks laser beams of the second and third wavelengths. The fourth transmission film transmits a laser beam of the second wavelength and blocks laser beams of the first and third wavelengths. The fifth reflecting film reflects a laser beam of the third wavelength. The fifth transmission film transmits a laser beam of the first wavelength and blocks laser beams of the second and third wavelengths. The sixth transmission film transmits a laser beam of the second wavelength and blocks laser beams of the first and third wavelengths. This allows the laser beam combiner 4 to transmit or reflect the first, second, and third wavelength laser beams when the second reflector 44 moves into or out of the linear optical path, thereby adjusting the wavelength of the laser beam output to the laser transmitter 5.

[0049] In one exemplary embodiment, such as Figure 5As shown, when the first reflector 43, the second reflector 44, and the semi-reflective mirror 45 are arranged sequentially along the first direction, a laser beam of the first wavelength is incident on the reflecting surface 431 of the first reflector 43. However, after being reflected by the reflecting surface 431, the first wavelength laser beam exits onto the second reflector 44, which blocks the first wavelength laser beam from continuing to propagate in the linear optical path. A laser beam of the second wavelength is incident on the reflecting surface 441 of the second reflector 44. After being reflected by the reflecting surface 441, the second wavelength laser beam exits onto the transmitting surface 452 of the semi-reflective mirror 45, thus allowing the second wavelength laser beam to be transmitted sequentially through the transmitting surface 452 and the reflecting surface 451 before exiting onto the laser transmitter 5. A laser beam of the third wavelength is incident on the reflecting surface 451 of the semi-reflective mirror 45, so that the third wavelength laser beam can be reflected by the reflecting surface 451 before exiting onto the laser transmitter 5. This enables the laser beams of the second and third wavelengths to be combined and transmitted to the laser transmitter 5, allowing the laser transmitter 5 to simultaneously transmit the second and third wavelength laser beams to the surgical site, thereby achieving simultaneous precision cutting and hemostasis.

[0050] In another exemplary embodiment, such as Figure 6 As shown, the laser beam combiner 6 can drive the second reflector 44 to move a preset distance along the second direction. This preset distance is greater than the spot diameter of the first reflector 43, and can be, for example, 4 mm, ensuring that the second reflector 44 is completely removed from the linear optical path. At this time, a laser beam of the first wavelength is incident on the reflecting surface 431 of the first reflector 43. After being reflected by the reflecting surface 431, the first wavelength laser beam exits onto the transmitting surface 452 of the semi-reflective mirror 45, allowing the first wavelength laser beam to be transmitted sequentially through the transmitting surface 452 and the reflecting surface 451 before exiting to the laser transmitter 5. A laser beam of the second wavelength is incident on the reflecting surface 441 of the second reflector 44, but after being reflected by the reflecting surface 441, the second wavelength laser beam cannot be transmitted to the laser transmitter 5. A laser beam of the third wavelength is incident on the reflecting surface 451 of the semi-reflective mirror 45, so that the third wavelength laser beam can be reflected by the reflecting surface 451 before exiting to the laser transmitter 5. Thus, the laser beam combiner 6 drives the second reflector 44 to move along the second direction, thereby combining the first wavelength laser beam and the third wavelength laser beam to the laser transmitter 5, so that the laser transmitter 5 can simultaneously transmit the first wavelength laser beam and the third wavelength laser beam to the surgical site, so as to achieve the simultaneous execution of explosive cutting and hemostasis.

[0051] Furthermore, in another exemplary embodiment, multiple reflectors can be arranged in the optical path between the first laser generator 1, the second laser generator 2, and the third laser generator 3 and the laser transmitter 5, so that the first wavelength laser beam, the second wavelength laser beam, and the third wavelength laser beam can be reflected by the multiple reflectors in the optical path and output to the laser transmitter 5. This enables the first wavelength laser beam, the second wavelength laser beam, and the third wavelength laser beam to be combined into a single beam and simultaneously transmitted to the surgical site by the laser transmitter 5. This allows the simultaneous execution of multiple functions such as tissue cutting, hemostasis, and assisted vaporization.

[0052] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
