Description

Technical Field

[0001] The present invention relates to a medical cold light source system and a control method thereof, and belongs to the technical field of optical equipment. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] Endoscopic systems are widely used in various diagnosis and treatment departments of hospitals. Operations performed in different departments have different requirements for the thickness of the endoscope. For example, general surgery and gynecological surgery usually use thicker endoscopes, while joint, ear, nose and throat and urology surgeries require thinner endoscopes.

[0004] The light aperture of a thicker endoscope is relatively large, while the light aperture of a thinner endoscope is relatively small. In the endoscope system, the light input end of the light guide is connected to the cold light source host, and the light output end of the light guide is connected to the endoscope, thereby forming an illumination light path. If the light aperture of the cold light source host or the light guide does not match the light aperture of the endoscope, it will cause inconvenience in use.

[0005] For example, when the light aperture of the cold light source host or the light guide is smaller than that of the endoscope, the endoscope illumination is uneven and the edge field of view is darker; if the light aperture of the cold light source host or the light guide is larger than that of the endoscope, excessive light energy will be converted into heat energy, causing overheating at the interface and poor grip for the operator; and after long-term accumulation of heat, it is easy to damage the light-entering end face and even the light-emitting components inside the cold light source host, reducing the life of the equipment and affecting the lighting effect during surgery.

[0006] The prior art CN220608292U discloses a conversion interface of a cold light source, which, when in use, is used to replace the light guide interface by rotating the conversion joint, thereby converting the light guide interface to assemble a light guide of corresponding specifications, thereby facilitating replacement and saving assembly time. However, when in use, the conversion structure of the cold light source cannot unify the aperture of the entire light path from the source of light emission, and requires manual operation by the user, which is time-consuming and laborious.

[0007] Therefore, it is necessary to design a cold light source system, which is not only compatible with light guide beams of various light apertures, but also can automatically match the corresponding light guide components, which can not only meet the lighting effect, but also unify the light aperture of the optical path, improve lighting efficiency, and avoid equipment damage.

[0036] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes.

For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0037] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present.

[0040] Figure 1 It is a principle block diagram of a cold light source host 2 according to an embodiment of the present disclosure. Figure 2 It is a schematic structural diagram of a light guide component 1 according to one embodiment of the present disclosure.

[0041] like Figure 1 and Figure 2 As shown, the medical cold light source system of the present disclosure may include components such as a light guide component 1 and a cold light source host 2 .

[0042] Refer to Figure 2 The light guide component 1 of the present disclosure includes a light input end 11 and a light output end 12. When the medical cold light source system of the present disclosure is used, the light input end 11 of the light guide component 1 is used to connect to the cold light source host 2, and the light output end 12 is used to connect to the endoscope.

[0043] Figure 3It is a schematic structural diagram of the light incident end of a light guide component according to an embodiment of the present disclosure.

[0044] In a specific embodiment, Figure 2 and Figure 3 As shown, the light guide component 1 includes a connector 111 and a light guide 113, the connector 111 has a central hole, the outer diameter of one end of the light guide 113 is the same or substantially the same as the inner diameter of the central hole of the connector 111, and the outer diameter of one end of the light guide 113 is inserted into the central hole of the connector 111. Thus, the light input end 11 of the light guide component 1 can be formed by the connector 111 of the present disclosure and one end of the light guide 113 inserted into the connector 111. In other words, the illumination light generated by the cold light source host 2 will be transmitted from one end of the light guide 113 to the other end thereof, and thus transmitted to the endoscope.

[0045] Since endoscopes have different sizes, the size of the light guide 113 needs to be the same or approximately the same as the size required by the endoscope, so the light guide 113 can have different diameters (outer diameters) in different light guide components 1. In addition, considering that the interface size of the cold light source host 2 remains unchanged, the connectors 111 of different light guide components 1 have the same outer diameter, so that the light guide component 1 can be easily inserted into the cold light source host 2 and other components.

[0046] In order to enable the connecting member 111 to form a fixed connection relationship with the light guide 113 , in the present disclosure, the center holes of the connecting members 111 of different light guide components 1 have different inner diameters, so that these connecting members 111 can match the size of the light guide 113 .

[0047] In a preferred embodiment, the connecting member 111 can be made of metal material, that is, it is formed into a metal structural member, and can be used for guiding, limiting and connecting the light guide component 1 and the cold light source host 2 .

[0048] In the present disclosure, the light guide component 1 further includes: a feature unit 112, which is used to mark the outer diameter of the light guide 113. Specifically, the predefined feature information can be obtained through the feature unit 112 of the present disclosure, that is, the current light aperture information of the light guide component 1 can be obtained.

[0049] The characteristic unit 112 may be a specific image, and the specific image may be coated on the surface of the connecting member 111. In another embodiment, the characteristic unit 112 may be a magnetic element, and is disposed on the connecting member 111.

[0050] like Figure 1As shown, the cold light source host 2 of the present disclosure may include components such as a cold light source light output interface 21 , a main control module 22 , a light source driving module 23 and a light source module 24 .

[0051] The cold light source light output interface 21 is a hollow structure made of metal, and thus the connecting member 111 can be inserted into the cold light source light output interface 21 and fixedly connected to the cold light source light output interface 21 .

[0052] The main control module 22 is a microcontroller, which is used to control the entire medical cold light source system; the light source driving module 23 is a constant current driver with adjustable output current, which is used to drive the light source module 24; the light source module 24 is a high-power semiconductor light source, which is used to generate an illumination light signal. More preferably, the main control module 22 of the present disclosure can be electrically connected to the light source driving module 23, and the light source driving module 23 is electrically connected to the light source module 24, so that the light source module 24 generates illumination light that meets the requirements by controlling the light source driving module 23.

[0053] More preferably, the cold light source host 2 of the present disclosure may further include a feature recognition module 25 and a light beam adjustment module 26 .

[0054] Among them, the feature recognition module 25 can be a non-contact sensor for identifying the feature information recorded in the feature unit 112. For example, when the feature unit 112 is an image (such as a QR code), the feature recognition module 25 can be an image sensor (such as a camera). When the feature unit 112 is a magnetic element, the feature recognition module 25 can be a magnetic sensor (such as a Hall element or a reed switch, etc.). Accordingly, the feature recognition module 25 of the present disclosure can be electrically connected to the main control module 22, so that the feature information of the feature unit 112 detected by the feature recognition module 25 is transmitted to the main control module 22.

[0055] Figure 4 It is a structural schematic diagram of a beam adjustment module of a cold light source host according to an embodiment of the present disclosure. Figure 5 It is a schematic diagram of the exploded structure of a beam adjustment module of a cold light source host according to an embodiment of the present disclosure. Figure 6 is a schematic structural diagram of a rotating assembly according to an embodiment of the present disclosure. Figure 7 It is a schematic structural diagram of a light guide module according to one embodiment of the present disclosure.

[0056] The light beam adjustment module 26 of the present disclosure is used to receive the illumination light generated by the light source module 24 and provide the illumination light to the light guide component 1. Specifically, Figures 4 to 7 As shown, the beam adjustment module 26 of the present disclosure may include: a first support seat 2605, a second support seat 2621 and a rotating component and other structures.

[0057] The first support seat 2605 and the second support seat 2621 can be fixed on the same component, and the relative position between the first support seat 2605 and the second support seat 2621 remains unchanged, so that the first support seat 2605 and the second support seat 2621 are used for fixed support of the entire beam adjustment module 26. In a preferred embodiment, the second support seat 2621 is arranged at an interval with the first support seat 2605; in this case, the rotating assembly can be located between the first support seat 2605 and the second support seat 2621.

[0058] The rotating component can be rotatably disposed on the first support seat 2605 and the second support seat 2621, and the rotating component can include at least two light guide modules 2618, and the center lines of the light guide modules 2618 are spaced apart from the rotation axis of the rotating component. Thus, when the rotating component rotates, the light guide modules 2618 can revolve along the rotation axis of the rotating component, so that different light guide modules 2618 can cooperate (align) with the light guide component 1, and at this time, the illumination light can be transmitted to the light guide component 1 through the light guide modules 2618.

[0059] In other words, the light beam adjustment module 26 of the present invention includes at least two light guide modules 2618, each light guide module 2618 having a light output end 26183, and the light output ends 26183 of different light guide modules 2618 have different sizes, wherein the light guide component 1 can be selectively connected to one of the light guide modules 2618 in the light beam adjustment module 26, so that the light aperture of the light guide component 1 is the same or approximately the same as the light aperture of the light guide module 2618, that is, the light beam adjustment module is used to match the light guide component 1 with a beam aperture that is suitable for it.

[0060] More specifically, if Figure 4 and Figure 5 As shown, the rotating assembly of the present disclosure may include: a first rotating disk 2613, a second rotating disk 2619 and a light guide module 2618; wherein the first rotating disk 2613 and the second rotating disk 2619 are both formed into a disc-shaped structure. A plurality of first rotating disk mounting holes 2614 are provided on the first rotating disk 2613; the number of the first rotating disk mounting holes 2614 may be the same as the number of the light guide modules 2618, for example, the number of the first rotating disk mounting holes 2614 and the number of the light guide modules 2618 are both set to n, and n is a natural number greater than or equal to 2. In a specific embodiment, n may be equal to 3. Of course, the number of the first rotating disk mounting holes 2614 may also be greater than the number of the light guide modules 2618, in which case, the light guide modules 2618 may not be provided in some of the first rotating disk mounting holes 2614.

[0061] The first rotating disk mounting hole 2614 can be formed as a stepped hole, and the larger diameter portion of the stepped hole is the same as the outer diameter of the light guide module 2618, thereby, one end of the light guide module 2618 can be inserted into the first rotating disk mounting hole 2614 and fixed in the first rotating disk mounting hole 2614.

[0062] Similarly, a plurality of second rotating disk mounting holes 2620 are provided on the second rotating disk 2619; the number of the second rotating disk mounting holes 2620 may be the same as the number of the light guide modules 2618, for example, the number of the second rotating disk mounting holes 2620 and the number of the light guide modules 2618 are both set to three. Of course, the number of the second rotating disk mounting holes 2620 may also be greater than the number of the light guide modules 2618, in which case, the light guide modules 2618 may not be provided in some of the second rotating disk mounting holes 2620.

[0063] In addition, the number of the second rotating disk mounting holes 2620 can be the same as the number of the first rotating disk mounting holes 2614. The second rotating disk mounting holes 2620 can be formed as stepped holes, and the larger diameter portion of the stepped holes is the same as the outer diameter of the light guide module 2618, so that one end of the light guide module 2618 can be inserted into the second rotating disk mounting hole 2620 and fixedly connected to the second rotating disk mounting hole 2620.

[0064] Thus, the position of the light guide module 2618 of the present disclosure can be fixed. More preferably, the axis of the first rotating disk mounting hole 2614 is set to be evenly distributed along the circumference of the cylindrical surface with the rotation axis of the rotating component as the center line; similarly, the axis of the second rotating disk mounting hole 2620 is also set to be evenly distributed along the circumference of the cylindrical surface with the rotation axis of the rotating component as the center line. More preferably, the first rotating disk mounting hole 2614 and the second rotating disk mounting hole 2620 have approximately the same shape, so that after the light guide module 2618 of the present disclosure is fixed, the center line of the light guide module 2618 is also located on the cylindrical surface with the rotation axis of the rotating component as the center line. That is, the center line of the light guide module 2618 is parallel to the rotation axis of the rotating component, and the distance between the center lines of different light guide modules 2618 and the rotation axis of the rotating component is the same.

[0065] The light beam adjustment module 26 of the present disclosure can also be a driving device such as a motor 2601. Specifically, the motor 2601 can be a stepper motor, which can be directly or indirectly fixed on the first support seat 2605, so that the driving force provided by the motor 2601 can drive the rotating assembly to rotate and make the light guide module 2618 rotate around the rotation axis of the rotating assembly. Moreover, the motor 2601 can also be connected to the main control module 22, and the rotation speed and number of rotations of the motor 2601 can be controlled by the main control module 22.

[0066] The motor 2601 is also in transmission connection with one end of the first rotating shaft 2604, and the other end of the first rotating shaft 2604 passes through the center of the first gear 2602 and the first rotating shaft support hole 2606 in sequence, and is rotatably supported by the first rotating shaft support hole 2606. At this time, the first gear 2602 can be fixedly connected to the first rotating shaft 2604, and the first rotating shaft 2604, the first gear 2602 and the first rotating shaft support hole 2606 have the same axis, so that the motor 2601 can drive the first gear 2602 to rotate.

[0067] The first rotating shaft 2604 and the first gear 2602 are located on the same side of the first rotating shaft support hole 2606; the first gear 2602 and the second gear 2603 are meshed and connected to drive the second gear 2603 to rotate; the second gear 2603 and the second rotating shaft 2617 are located on both sides of the second rotating shaft support hole 2607, one end of the second rotating shaft 2617 passes through the second rotating shaft support hole 2607, and is mechanically connected to the second gear 2603, and the other end of the second rotating shaft 2617 passes through the center of the first rotating disk 2613 and the center of the second rotating disk 2619 in sequence and is supported in the third rotating shaft support hole 2622. Moreover, the second gear 2603, the first rotating disk 2613 and the second rotating disk 2619 are all fixedly connected to the second rotating shaft 2617. One end of the second rotating shaft 2617 is rotatably supported by the second rotating shaft support hole 2607, and the other end of the second rotating shaft 2617 is rotatably supported by the third rotating shaft support hole 2622.

[0068] The axes of the second gear 2603, the second rotating shaft support hole 2607, the first rotating disk 2613, the second rotating shaft 2617, the second rotating disk 2619 and the third rotating shaft support hole 2622 are the same (coaxial). The rotation of the second gear 2603 drives the second rotating shaft 2617 to rotate, and then drives the first rotating disk 2613 and the second rotating disk 2619 to rotate.

[0069] In the present disclosure, the first rotation shaft support hole 2606 and the second rotation shaft support hole 2607 are formed on the first support seat 2605 , and the third rotation shaft support hole 2622 is formed on the second support seat 2621 .

[0070] The light guide interface 2608 is formed as a cylindrical hollow metal structure, and one end of it can be fixed in the mounting hole of the first support seat 2605, and the other end can be formed with an external thread; at this time, the internal thread of the cold light source light output interface 21 can also cooperate with the external thread of the light guide interface 2608, so that the cold light source light output interface 21 can be fixed to the other end of the light guide interface 2608.

[0071] The light input end 11 of the light guide component 1 can be inserted into the interior of the cold light source light output interface 21, and can further extend through the light guide interface 2608 and the mounting hole of the first support seat 2605, and contact the light output end 26183 of the light guide module 2618, so that the illumination light can be transmitted from the light guide module 2618 to the light guide component 1.

[0072] In a preferred embodiment, the inner diameter of the light guide interface 2608 is the same as the inner diameter of the cold light source light output interface 21 , and both are adapted to the outer diameter of the light input end 11 .

[0073] In a preferred embodiment, a feature recognition hole 2609 is provided on the first support seat 2605; wherein, the feature recognition hole 2609 is a through hole, which is formed as a channel for collecting specific information of the feature unit 112. After the light input end 11 is inserted into the cold light source light output interface 21, the feature unit 112 and the feature recognition hole 2609 can be aligned and arranged, thereby, the feature recognition module 25 can detect / identify the feature unit 112 through the feature recognition hole 2609.

[0074] The first rotating disk 2613 is provided with a plurality of first limiting components 2615 in the circumference thereof, and the first limiting components 2615 are used to cooperate with the limiting seat 2610 to limit the circumferential position of the rotating assembly. Specifically, the first limiting components 2615 may be limiting grooves, and the limiting grooves may be U-shaped grooves.

[0075] In the present disclosure, the limiting seat 2610 may include a seat body and a C-shaped arm or an O-shaped arm disposed on the seat body, and the inner surface of the C-shaped arm or the O-shaped arm is provided with a second limiting component 2612, and the second limiting component 2612 is used to cooperate with the first limiting component 2615. In a preferred embodiment, the second limiting component 2612 may be a limiting marble. Thus, the limiting seat 2610 of the present disclosure can be formed into a clamping structure, At least n-1 and at most n limiting marbles are arranged on the inner surface of the C-shaped arm or the O-shaped arm. The limiting marbles are metal spherical structures, a part of which protrudes from the inner surface of the C-shaped arm or the O-shaped arm, and the rest is connected to the spring and buried inside the C-shaped arm or the O-shaped arm. Multiple limiting marbles are evenly arranged on the inner side of the C-shaped arm or the O-shaped arm, and the angle between adjacent limiting marbles is 360 / n°.

[0076] In a preferred embodiment, the number of the first limiting components 2615 is an integer multiple (ie, M times, M is greater than or equal to 1) of the number of the light guide modules 2618 , and the first limiting components 2615 are evenly spaced along the circumference of the first rotating disk 2613 .

[0077] There are at least two second limiting components 2612 , wherein the distance between two adjacent second limiting components 2612 in the circumferential direction of the C-arm or O-arm is the same as the distance between two adjacent first limiting components 2615 in the circumferential direction of the first rotating disk 2613 .

[0078] A position detection unit 2611 is disposed on the seat body of the limiting seat 2610 , and a position trigger unit 2616 is disposed on the first rotating disk 2613 . When the position trigger unit 2616 is opposite to the position detection unit 2611 or is located near it, the position trigger unit 2616 triggers the position detection unit 2611 .

[0079] In a preferred embodiment, the position trigger unit 2616 can be a magnetic part, and the position detection unit 2611 can be a Hall element or a reed switch, so that when the position detection unit 2611 detects the position trigger unit 2616, the first rotating disk 2613 can be in a preset position, and preferably, the preset position can be defined as the initial position.

[0080] In the present disclosure, the position trigger unit 2616 can be embedded in the outer circumference of the first rotating disk 2613 , and the position detection unit 2611 can be set on the upper surface of the seat body of the limiting seat 2610 .

[0081] The position detection unit 2611 may also be connected to the main control module 22 , so that the main control module 22 can know the current position (initial position) of the rotating component through the signal provided by the position detection unit 2611 .

[0082] Specifically, the main control module 22 can be connected to the motor 2601 and the position detection unit 2611 of the light beam adjustment module 26. Accordingly, the main control module 22 can control the rotation speed and rotation angle of the motor 2601, and can also obtain the initial position of the rotating component through the position detection unit, and calculate the angle that the motor 2601 needs to rotate according to the initial position of the rotating component obtained by the position detection unit and the target position that the rotating component needs to rotate to. Then, the main control module 22 can control the motor 2601 to rotate the corresponding angle, thereby enabling the appropriate light guide module 2618 to be aligned with the light guide component 1.

[0083] The light guide module 2618 is an integrated optical component used for focusing and transmitting light beams. The number of light guide modules 2618 can be the same as the number of types of light guide components 1, for example, both can be n. Each light guide module 2618 contains a focusing unit 26181 and a light rod unit 26182 inside, and is surrounded by a cylindrical sealing structure outside, wherein the focusing unit 26181 is an optical lens group, which is used to focus the light beam emitted by the light source module 24 to the light input end of the light rod unit 26182, and the light rod unit 26182 is a light guide glass, which is an elongated cylindrical structure, used for limiting the beam aperture and transmitting light, a part of which is placed inside the cylindrical sealing structure, and the rest is placed outside, and one end of the light rod unit 26182 located outside is formed as the light output end 26183 of the light guide module 2618. The diameters of the light rod units 26182 in different light guide modules 2618 correspond to the light apertures of different light guide components 1 one by one, and are different from each other. The lengths of the exposed parts of different light rod units 26182 are consistent.

[0084] Therefore, the beam adjustment module 26 of the present disclosure can match the beam aperture suitable for the light guide component 1. Moreover, the beam adjustment module 26 of the present disclosure is electrically connected to the main control module 22, and mechanically connected to the cold light source light output interface 21 and the light source module 24.

[0085] The medical cold light source system based on the above structure can identify a variety of light guide components 1 and automatically match the light guide components that are compatible with their light apertures. It is easy to use and has a high degree of automation, avoiding local light path heating or reduced light uniformity, and improving light output performance. In other words, the medical cold light source system disclosed in the present invention is not only compatible with light guide components 1 of various light apertures, but also can automatically match the corresponding light guide modules, which can not only meet the lighting effect, but also improve the lighting efficiency and avoid equipment damage.

[0086] Figure 8 is a flow chart of a control method of a medical cold light source system according to one embodiment of the present disclosure.

[0087] like Figure 8 As shown, the control method of the medical cold light source system disclosed in the present invention can control the above-mentioned medical cold light source system. Specifically, the control method of the medical cold light source system disclosed in the present invention can include the following steps: 102. The main control module 22 controls the rotating assembly to rotate to the initial position; at the initial position, a light guide module 2618 in the light beam adjustment module 26 is aligned with the light guide interface 2608, and the light guide module 2618 aligned with the light guide interface 2608 has a preset light aperture; 104. Insert the light guide component 1 into the cold light source light output interface 21, and the feature recognition module 25 recognizes the light aperture information of the light guide component 1, and transmits the light aperture information to the main control module 22; 106. The main control module 22 compares the light-clearing aperture of the light-guiding component 1 with the preset light-clearing aperture of the light-guiding module 2618 aligned with the light-guiding light guide interface 2608; when the light-clearing aperture of the light-guiding component 1 is the same as the preset light-clearing aperture, it is determined that the light-guiding component 1 is correctly connected to the light-guiding module 2618; when the light-clearing aperture of the light-guiding component 1 is different from the preset light-clearing aperture, the main control module 22 selects a suitable light-guiding module 2618 according to the light-clearing aperture of the light-guiding component 1, and obtains the rotation direction and rotation angle of the motor 2601 according to the position of the suitable light-guiding module 2618, the main control module 22 controls the motor 2601 to drive the rotating component to move, and aligns the suitable light-guiding module 2618 with the light-guiding light guide interface 2608, that is, moves the light-guiding module 2618 to the position between the light outlet of the light source module 24 and the light-guiding component 1.

[0088] Specifically, when the cold light source host 2 is powered on, the main control module 22 controls the motor 2601 to drive the first rotating disk 2613 to rotate to the initialization position. The specific initialization position is determined by the position detection unit 2611 and the position trigger unit 2616. At this position, a light guide module 2618 that determines the light aperture (beam aperture) is selected and limited to between the light outlet of the light source module 24 and the cold light source light outlet interface 21.

[0089] The operator selects light guide components 1 with different light apertures according to surgical requirements and inserts them into the cold light source light output interface 21. The feature recognition module 25 recognizes the light aperture information corresponding to the feature unit 112 and transmits it to the main control module 22. The main control module 22 further selectively controls the motor 2601 to drive the first rotating disk 2613 and the second rotating disk 2619 to rotate, thereby rotating the light guide module 2618 with matching light beam aperture and limiting it between the light output port of the light source module 24 and the cold light source light output interface 21.

[0090] After rotation and limiting, the central axes of the light outlet of the light source module 24, the light rod unit 26182 in the selected light guide module 2618, the cold light source light outlet interface 21 and the light through port of the light guide component 1 are coaxial.

[0091] The following is a brief description of the identification of the light aperture of the light guide component 1. In a feasible embodiment, the light guide component 1 can be of three types, that is, light guide components 1 with three different light apertures.

[0092] The characteristic unit 112 uses an annular magnetic element with the same parameters, which is embedded in the connector 111, and the positions of different characteristic units 112 are different; the characteristic recognition module 25 uses a magnetic sensor, which can convert the magnetic strength into a voltage signal and output it to the main control module 22; when different light guide components 1 are respectively inserted into the cold light source light output interface 21, the voltage signal strength output by the magnetic sensor is different, and based on the pre-defined system, the light aperture of the inserted light guide component 1 can be determined. Magnetic elements with different magnetic parameters can also be placed at the same position as the light input end characteristic unit 112.
