[0040] Therefore, 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] Since the fiber optic catheter 500 for endovascular ablation includes multiple optical fibers, the longer the catheter, the higher the cost. The optical guide arm 220, however, typically has multiple movable joints, allowing for directional turning and thus replacing some of the optical fibers. Therefore, adding an optical guide arm 220 between the endovascular laser ablation device and the catheter can reduce the length of the catheter used.

[0047] Because the diameter of blood vessels varies at different lesion sites and among different patients, different sizes of catheters are required. If a fixed-spot coupled fiber optic catheter 500 is used for different sizes of catheters, the required energy density can only be achieved by adjusting the laser energy. This can lead to low optical transmission efficiency for some sizes of catheters. Therefore, this invention incorporates an adjustable optical structure to adapt to different catheters.

[0048] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] Example 1

[0050] This utility model embodiment provides a laser emitting device, including: a laser emitting module 100, a laser transmission module 200, and a conduit connector 300; the emitting end of the laser emitting module 100 is connected to the conduit connector 300 through the laser transmission module 200; the laser transmission module 200 includes: an adjustable optical component 210 and a light guide arm 220; the adjustable optical component 210 is used to adjust the spot size of the laser emitted from the laser emitting module 100; the laser emitting module 100, the adjustable optical component 210, and the light guide arm 220 are connected in sequence, or the laser emitting module 100, the light guide arm 220, and the adjustable optical component 210 are connected in sequence; the conduit connector 300 is used to connect to an optical fiber conduit 500.

[0051] Specifically, the emitting end of the laser emitting module 100 is directly connected to the input end of the laser transmission module 200, ensuring that the laser beam can directly enter the laser transmission module 200. This connection typically requires precise alignment techniques to reduce energy loss of the laser during transmission.

[0052] The laser transmission module 200 mainly consists of two parts: an adjustable optical component 210 and a light guide arm 220. These two components work together to ensure efficient laser transmission and allow for adjustment of laser parameters according to different treatment needs. Adding a light guide arm 220 between the laser emission module 100 and the catheter connector 300 reduces the length of the catheter. The emitted laser passes through the light guide arm 220 before entering the catheter and finally acting on the target location. The adjustable optical module can be a combination of various optical elements, specifically determined based on the required spot size of the catheter. For example, if the catheter size is available in 1.0mm and 2.0mm sizes, and the required spot sizes are 1.1mm and 2.1mm respectively, the adjustable optical module can be used to adjust the spot size to 1.1mm and 2.1mm.

[0053] The adjustable optical assembly 210 typically includes one or more adjustable optical lenses that can be moved under the drive of a motor, thereby changing the distance between the lenses or their position relative to the laser beam to adjust the spot size. Additionally, the assembly may include a position sensor for precise control of the lens position.

[0054] The adjustable optical component 210 is the core part of the conduction module, primarily responsible for adjusting the spot size of the laser beam. This function is particularly important for adapting to different sized catheters because different sized catheters require different spot sizes to achieve optimal treatment results.

[0055] The function of the light guide arm 220 is to effectively transmit the laser beam, adjusted by the adjustable optical component 210, to the guide tube connector 300. The design of the light guide arm 220 directly affects the efficiency and accuracy of laser transmission. The design of the light guide arm 220 needs to fully consider the characteristics of the laser beam, such as wavelength and power, to ensure that the beam does not lose energy due to scattering, absorption, or other problems during transmission.

[0056] Furthermore, it is easy to understand that the adjustable optical component 210 can also be installed at the front end of the light guide arm 220, that is, the laser emitting module 100, the adjustable optical component 210, and the light guide arm 220 are connected in sequence. If the maximum diameter of the adjustable light spot is within the transmission diameter range of the light guide arm 220, the adjustable optical component 210 can be placed at the front end of the light guide arm 220; if the required light spot exceeds the transmission diameter, the adjustable optical component 210 is placed at the rear end of the light guide arm 220, that is, the laser emitting module 100, the light guide arm 220, and the adjustable optical component 210 are connected in sequence, which can reduce the size of the light guide arm 220 design.

[0057] See Figure 1The schematic diagram shown in this embodiment of the present invention provides a laser emitting device in which an adjustable optical component 210 is mounted at the front end of a light guide arm 220. The connection between the emitting end of the laser emitting module 100 and the catheter connector 300, as well as the design of the adjustable optical component 210 and the light guide arm 220 in the laser transmission module 200, are key factors in ensuring that the laser medical device can achieve maximum effectiveness in intravascular ablation treatment. This design not only improves the laser transmission efficiency but also allows the same device to adapt to catheters of different sizes by adjusting the spot size, greatly improving the applicability and treatment effect of the device.

[0058] This invention provides a laser emitting device, comprising: a laser emitting module 100, a laser transmission module 200, and a conduit connector 300; the emitting end of the laser emitting module 100 is connected to the conduit connector 300 through the laser transmission module 200; the laser transmission module 200 includes: an adjustable optical component 210 and a light guide arm 220; the adjustable optical component 210 is used to adjust the spot size of the laser emitted from the laser emitting module 100; the laser emitting module 100, the adjustable optical component 210, and the light guide arm 220 are connected in sequence, or the laser emitting module 100, the light guide arm 220, and the adjustable optical component 210 are connected in sequence; the conduit connector 300 is used to connect an optical fiber conduit 500; by adjusting the spot size through the adjustable optical component 210, the laser transmission efficiency is improved, and by using the light guide arm 220, the length of the conduit used is reduced, thus lowering the cost.

[0059] Furthermore, in some preferred embodiments of this invention, the light guide arm 220 is malleable along its light guiding direction.

[0060] Specifically, the light guide arm 220 can be bent and adjusted in shape to a certain extent according to the operator's needs, thereby improving operational flexibility. This plasticity is achieved through special internal structures and materials of the light guide arm 220, such as using flexible materials or employing multiple rotatable joints connected together.

[0061] Furthermore, in some preferred embodiments of this utility model, the light guide arm 220 is a multi-joint light guide structure; a reflector is provided at each joint of the light guide arm 220.

[0062] For details, please refer to [link / reference]. Figure 1 The light guide arm 220 is a multi-jointed light guide structure; each joint of the light guide arm 220 is equipped with a reflector. This design not only gives the light guide arm 220 high flexibility and adaptability, but also ensures the efficiency and accuracy of the laser beam during transmission. The reflector at each joint is precisely positioned to ensure that the laser beam can still be accurately transmitted to the target position after multiple reflections.

[0063] Furthermore, in some preferred embodiments of the present invention, the adjustable optical component 210 includes: a first dimming unit; the first dimming unit includes: a first adjusting motor and a first dimming lens 211; the first adjusting motor is used to drive the first dimming lens 211 to move along the transmission direction of the laser within the first dimming unit.

[0064] For details, see Figure 2 The diagram shown is a structural schematic of an adjustable optical component 210 provided in this embodiment of the present invention; the dashed line indicates the laser transmission direction. The first adjustment motor (not shown) is the power source of the first dimming unit, and its main function is to drive the first dimming lens 211 to move along the laser transmission direction within the first dimming unit. This design allows doctors or operators to input commands through a console or computer system according to actual treatment needs, and the adjustment motor will move the dimming lens accordingly, thereby changing the spot size of the laser beam.

[0065] The first adjustment motor is usually a stepper motor or a servo motor because they can provide precise position control and repeatability, ensuring that the dimming lens can be moved precisely to the desired position.

[0066] The first dimming lens 211 is a key component for adjusting the laser spot size. Located in the laser transmission path, it adjusts the focal point of the laser beam by changing the distance between the lens and the guide arm 220, thereby changing the spot size. The lens is typically made of high-quality optical materials, such as BK7 glass or quartz, offering excellent optical performance and durability. The shape and curvature of the lens are precisely calculated to ensure that the desired spot size is produced at different positions.

[0067] Furthermore, in some preferred embodiments of this utility model, the laser emitting device further includes: a control module 400; the first dimming unit further includes: a first position sensor; the first position sensor is used to acquire the position information of the first dimming lens 211 and send the position information of the first dimming lens 211 to the control module 400.

[0068] Specifically, the first position sensor is used to acquire the position information of the first dimming lens 211 and send this information to the control module 400. This function is crucial for ensuring that the spot size of the laser beam can be precisely adjusted. The sensor typically employs a high-precision position sensor such as a photoelectric encoder or a Hall effect sensor, which can monitor the position of the dimming lens in real time and feed the position data back to the control module 400.

[0069] In actual operation, after the operator connects the conduit to the laser device, the device reads the conduit's specifications and the control unit calculates the precise position that the first dimming lens 211 needs to move to, then instructs the first adjustment motor to move the lens. As the lens position changes, the size of the laser beam spot after passing through the lens also changes until it reaches the preset size. During this process, the first position sensor continuously monitors the actual position of the lens and transmits the data back to the control module 400 in real time, forming a closed-loop control system to ensure the accuracy and stability of the adjustment.

[0070] Furthermore, in some preferred embodiments of this utility model, the adjustable optical component 210 includes: a second dimming unit; the second dimming unit includes: a second adjusting motor 212, a wheel 213 and a plurality of second dimming lenses 214; wherein, the curvature of all the second dimming lenses 214 is different; the second adjusting motor 212 is connected to the wheel 213 for transmission; all the second dimming lenses 214 are arranged at intervals along the circumference of the wheel 213 on the wheel 213.

[0071] For details, please refer to [link / reference]. Figure 2 The wheel 213 is the core structure of the second dimming unit, with multiple second dimming lenses 214 spaced circumferentially along its upper edge. Each lens has a different curvature, thus producing light spot sizes of varying sizes. The design of the wheel 213 needs to ensure rapid switching between lenses while maintaining lens cleanliness and stability. The wheel 213 is typically made of lightweight materials and equipped with precision bearings and locking mechanisms.

[0072] Multiple secondary dimming lenses 214 are key to achieving diverse spot size adjustments. Because each lens has a different curvature, they can produce spot sizes of varying sizes at different locations. The secondary dimming lenses 214 are also made of high-quality optical materials, and the shape and curvature of each lens are specifically designed to meet specific spot size requirements.

[0073] The second adjusting motor 212 is connected to the wheel 213 for transmission, and its main function is to drive the wheel 213 to rotate. By rotating the wheel 213, different paths can be selected for the laser beam to enter through different dimming lenses, thereby changing the laser spot size. Similarly, stepper motors or servo motors are usually chosen because they can provide precise position control and repeatability.

[0074] In actual operation, after the operator connects the conduit to the laser device, the device reads the conduit's specifications. The control unit then calculates the required spot size and instructs the first and second adjustment motors 212 to perform corresponding operations. The first dimming unit is responsible for fine-tuning the spot size, while the second dimming unit provides a wider adjustment range. Through their coordinated operation, precise and diverse spot size adjustments can be achieved.

[0075] Furthermore, in some preferred embodiments of this utility model, the second dimming unit further includes: a second position sensor; the second position sensor is used to obtain the rotation angle of the wheel 213 and send the rotation angle of the wheel 213 to the control module 400.

[0076] Specifically, the second position sensor is a key component of the second dimming unit, used to acquire the rotation angle of the wheel 213 and send this information to the control module 400. This function is crucial for ensuring the accurate selection and use of specific dimming lenses. Typically, a high-resolution photoelectric encoder or magnetic sensor is used, which can monitor the rotation angle of the wheel 213 in real time and feed the angle data back to the control module 400.

[0077] By integrating the first and second dimming units, the adjustable optical assembly 210 not only possesses the ability to precisely adjust the laser spot size but also provides more adjustment options to adapt to different treatment needs. This design greatly enhances the versatility of the device and the treatment effect, enabling doctors to provide patients with more personalized and precise treatment plans.

[0078] Furthermore, in some preferred embodiments of this invention, the second position sensor is a Hall sensor or a resistance sensor.

[0079] Specifically, Hall effect sensors or resistance sensors can accurately measure the rotation angle and speed of the wheel 213. This detection method improves the accuracy and reliability of the system. Hall effect sensors are characterized by high sensitivity and low power consumption; resistance sensors provide stable measurement results and are suitable for scenarios requiring high precision.

[0080] Furthermore, in some preferred embodiments of this utility model, the connector of the optical fiber conduit 500 is provided with a conduit tag; wherein, the conduit tag is used to store the parameter information of the optical fiber conduit 500; the conduit connector 300 is provided with an identification module; the identification module is used to identify the conduit tag, obtain the parameter information of the optical fiber conduit 500, and send the parameter information of the optical fiber conduit 500 to the control module 400.

[0081] For details, see Figure 3The diagram shown illustrates the connection between a conduit connector 300 and an optical fiber conduit 500, as provided in this embodiment of the present invention. The optical fiber conduit 500 is a crucial channel for laser transmission. To ensure that the laser equipment can accurately identify and utilize the parameter information of the optical fiber conduit 500, a conduit label is placed on the connector of the optical fiber conduit 500. This label stores parameter information of the optical fiber conduit 500, such as its model, specifications, and spot size. Simultaneously, the conduit connector 300 is equipped with an identification module capable of recognizing the conduit label and acquiring the parameter information of the optical fiber conduit 500. Once the identification module acquires this information, it sends it to the control module 400 for processing and adjustment.

[0082] Furthermore, the catheter tag is an electronic tag capable of storing various parameter information about the fiber optic catheter 500. This information can be written into the tag during the production process and read by the identification module when needed. Correspondingly, the identification module is a reader / writer capable of communicating with the catheter tag and reading the information stored therein. Once the parameter information of the fiber optic catheter 500 is obtained, the identification module sends this information to the control module 400 for processing.

[0083] For example, the identification scheme here can adopt an RFID solution, where the conduit connector 300 is equipped with an RFID tag to store the conduit model, and can also store parameters such as conduit specifications and energy density. The connector end of the device is equipped with an RFID reader / writer, which reads the corresponding parameters when the conduit is fully connected. Then, the light spot is adjusted to the required size by the aforementioned adjustable optical unit.

[0084] In actual operation, once the operator determines the required catheter size for treatment, the fiber optic catheter 500 is connected to the device. The identification module automatically identifies the catheter label and obtains the parameter information of the fiber optic catheter 500. After receiving this information, the control unit calculates the precise positions that the first dimming lens 211 and the wheel 213 need to reach according to a preset program. Subsequently, it instructs the first adjustment motor and / or the second adjustment motor 212 to perform the corresponding operations. The first dimming unit can be responsible for fine-tuning the spot size, while the second dimming unit can provide a wider adjustment range. Through the coordinated work of the two and the accurate identification and information transmission of the identification module, precise and diverse spot size adjustment can be achieved. During this process, the first position sensor and the second position sensor continuously monitor the actual position / angle of the lens and the wheel 213 and transmit the data back to the control module 400 in real time, forming a closed-loop control system to ensure the accuracy and stability of the adjustment.

[0085] By integrating the first dimming unit, the second dimming unit, and the catheter label and identification module on the fiber optic catheter 500, the adjustable optical assembly 210 not only possesses the ability to precisely adjust the laser spot size but also provides more adjustment options to adapt to different treatment needs. This design greatly improves the versatility of the device and the treatment effect, enabling doctors to provide patients with more personalized and precise treatment plans.
