[0037] Referring to Figures 1 to 13 As shown, according to the embodiment of the present application, a light source host for endoscope is provided, comprising a box body 10 and a light source module 20, wherein the box body 10 is provided with a mounting cavity 11 and a mounting hole 12 communicating between the mounting cavity 11 and the outside of the box body; the light source module 20 comprises a light emitting unit 21 and a plurality of types of light source interface assemblies 22, the light emitting unit 21 is mounted in the mounting cavity 11, the light emitting unit 21 is provided with a light source interface 211, the light source interface assembly 22 is detachably connected with the light source interface 211 through the mounting hole 12, and the plurality of types of light source interface assemblies 22 are used to be adaptively connected with a plurality of types of light guide fiber bundles 30 one by one.

[0038] In the embodiment, the light source host for endoscope is selectively detachably connected with the light emitting unit 21 through the plurality of types of light source interface assemblies 22, and the light source interface assembly 22 can be detached from the outside of the box body 10, the plurality of types of light source interface assemblies 22 are used to be adaptively connected with the plurality of types of light guide fiber bundles 30, when different types of light guide fiber bundles 30 are needed to be selected according to different application scenarios, the light source interface assembly 22 corresponding to the needed light guide fiber bundle 30 can be directly replaced from the outside of the box body 10, the quick switching of different types of light guide fiber bundles 30 is realized, and the adaptability of the light source host for endoscope is improved.

[0039] Further, the light source interface assembly 22 of the embodiment comprises a conversion head 221, the conversion head 221 is detachably connected with the light source interface 211 through threads or buckles, the length direction of the conversion head 221 is provided with an interface channel 2211, and the interface channel 2211 is used to pass through the light guide fiber bundle 30. It can be understood that the interface channel 2211 is arranged through the length direction of the conversion head 221, by arranging the interface channel 2211 on the conversion head 221, the light guide fiber bundle 30 can better contact with the light source interface 211 of the light emitting unit 21 after passing through the conversion head 221, and the light guide fiber bundle 30 can also be radially limited through the light source interface 211, preventing the light guide fiber bundle 30 from moving in a large range in the radial direction in the interface channel 2211, and improving the light guiding efficiency of the light guide fiber bundle 30.

[0040] Specifically, the conversion head 221 comprises a connecting portion 2212 and a dial 2213, one end of the connecting portion 2212 is fixedly connected with the dial 2213, the other end of the connecting portion 2212 is provided with an external thread 2214, and the light source interface 211 is provided with an internal thread 2111 matched with the external thread 2214. Specifically, the dial 2213 is integrally formed or detachably fixedly connected with the connecting portion 2212, the dial 2213 is provided in a disc structure, the connecting portion 2212 is provided in a tubular structure, the external thread 2214 at one end of the connecting portion 2212 is matched with the internal thread 2111 provided on the light source interface 211, thereby achieving detachable connection of the light source interface assembly 22 and the light emitting unit 21 and improving the convenience of the light source main machine.

[0041] Further, the dial 2213 is provided with a first positioning portion 2215, the outer surface of the box body 10 is provided with a matching groove 13 and a second positioning portion 14, the bottom of the matching groove 13 is provided with a mounting hole 12, and the second positioning portion 14 is located at the outer circumferential side of the matching groove 13; wherein, when the light source interface assembly 22 is connected with the light emitting unit 21 through the mounting hole 12, the dial 2213 is located in the matching groove 13, and the first positioning portion 2215 and the second positioning portion 14 are aligned.

[0042] Referring to Figure 5 The first positioning portion 2215 comprises an L-shaped groove provided on the disc surface and the side surface of the dial 2213, the number of the L-shaped grooves is at least two or more, and the second positioning portion 14 can have any shape such as a dot shape. When the light source interface assembly 22 is connected with the light emitting unit 21 through the mounting hole 12, the threaded connection of the light source interface assembly 22 and the light emitting unit 21 is achieved by screwing the dial 2213. When the dial 2213 enters the matching groove 13 on the outer surface of the box body 10, whether the first positioning portion 2215 of the L-shaped groove is aligned with the second positioning portion 14 is determined by the relative gap y between the dial 2213 and the matching groove 13, thereby determining whether the light source interface assembly 22 is installed in place. When the fitting gap y between the dial 2213 and the matching groove 13 reaches a preset gap and the first positioning portion 2215 is aligned with the second positioning portion 14, it is determined that the light source interface assembly 22 is installed in place, and the dial 2213 is stopped from being screwed. By providing at least two or more L-shaped grooves for the first positioning portion 2215, the L-shaped grooves can be used to assist the screwing of the dial 2213 when the light source interface assembly 22 needs to be installed or disassembled.

[0043] The first positioning part 2215 (L-shaped groove) arranged on the dial 2213 and the second positioning part 14 on the outer surface of the box body 10 are aligned to determine whether the light source interface assembly 22 is installed in place by combining the fitting gap y between the dial 2213 and the adapter slot 13, ensuring the accurate connection of the light source interface assembly 22 and the light emitting unit 21, allowing the user to install the light source interface assembly 22 more quickly and accurately. By setting the first positioning part 2215 as an L-shaped groove, the first positioning part 2215 can not only be used to detect whether the light source interface assembly 22 is installed in place, but also assist in the rotation of the dial 2213. Since the dial 2213 is set as a disc structure, it may slip during rotation due to factors such as hand sweat of the operator. The first positioning part 2215 of the L-shaped groove can provide assistance for rotating the dial 2213, and when the dial 2213 enters the adapter slot 13, it is difficult to rotate the dial 2213 if no groove is set on the dial 2213, improving the efficiency of installing or dismounting the light source interface assembly 22 and the convenience of using the light source host. By adapting the adapter slot 13 on the outer surface of the box body 10 with the dial 2213, the height of the dial 2213 protruding from the outer surface of the box body 10 when the light source interface assembly 22 is connected to the light emitting unit 21 can be reduced, improving the aesthetics of the light source host.

[0044] Further, the light source interface assembly 22 of the present embodiment further comprises at least one locking member 222, which is arranged on the conversion head 221 and extends radially along the conversion head 221. The locking member 222 is configured to limit the movement of the optical fiber bundle 30 in the length direction of the interface channel 2211 when the optical fiber bundle 30 is inserted into the interface channel 2211. That is, the conversion head 221 can be provided with one locking member 222, or two or more locking members 222. By arranging the locking member 222 radially on the conversion head 221 to limit the movement of the optical fiber bundle 30 in the length direction of the interface channel 2211, the connection between the optical fiber bundle 30 and the light source interface assembly 22 is ensured to be stable and reliable, which can ensure the quality of optical signal transmission of the light source host.

[0045] Optionally, the locking member 222 comprises a knob screw 2221, the conversion head 221 is provided with a screw hole 2216, the outer surface of the optical fiber bundle 30 is provided with a limiting groove 31, when the optical fiber bundle 30 is inserted into the interface channel 2211, the knob screw 2221 passes through the screw hole 2216 and abuts against the limiting groove 31. The knob screw 2221 comprises a pin body, an elastic element and a knob, the length direction of the pin body is provided with a positioning hole, the elastic element is arranged in the positioning hole, the knob abuts against the end of the elastic element, and the knob is at least partially exposed outside the positioning hole. Of course, in other embodiments of the present application, the locking member 222 can also be provided as a buckle locking structure, as long as other deformation modes or combinations under the concept of the present application are within the protection scope of the present application.

[0046] Specifically, the limiting groove 31 on the outer surface of the optical fiber bundle 30 comprises an arc-shaped groove, the arc-shaped groove extends along the outer periphery of the optical fiber bundle 30, the elastic element of the knob screw comprises a spring, when the optical fiber bundle 30 is inserted into the interface channel 2211, the outer surface of the optical fiber bundle 30 without the arc-shaped groove first contacts the knob of the knob screw 2221, the knob is compressed by the force of the optical fiber bundle 30 and moves towards the spring, so that the optical fiber bundle 30 is completely inserted into the interface channel 2211, when the arc-shaped groove of the optical fiber bundle 30 moves to the position of the knob, the knob abuts against the arc-shaped groove under the elastic force of the spring, because of the structural characteristics of the arc-shaped groove and the knob, and the knob is subjected to the elastic force of the spring, the optical fiber bundle 30 can be fixed at a specific position without applying external force to the optical fiber bundle 30. The arc-shaped groove is preferably an arc-shaped groove penetrating the outer periphery of the optical fiber bundle 30, which can lock the optical fiber bundle 30 by the locking member 222 regardless of how the optical fiber bundle 30 is inserted into the interface channel 2211. When the optical fiber bundle 30 is locked by the knob screw 2221, there is a fitting gap between the outer surface of the optical fiber bundle 30 and the inner surface of the interface channel 2211, which represents the locking depth x of the knob screw 2221, and the size of the locking depth x can be adjusted by the knob screw 2221 to affect the plugging and unplugging feeling of the optical fiber bundle 30.

[0047] The knob of the knob screw 2221 is matched with the arc-shaped groove on the outer surface of the optical fiber bundle 30, so as to realize accurate locking and fixing of the optical fiber bundle 30. Not only the stability of the optical fiber bundle 30 in the interface channel 2211 is ensured, but also the problem of optical signal transmission caused by loosening or falling is avoided. Since the arc-shaped groove extends along the outer periphery of the optical fiber bundle 30, and the knob of the knob screw 2221 can compress the spring and move inward after being subjected to the force of the optical fiber bundle 30, the locking mechanism has strong adaptability. No matter how the optical fiber bundle 30 is inserted into the interface channel 2211 at what angle or in what way, the knob can automatically adjust the position through the elastic force of the spring, and finally cooperate with the arc-shaped groove to realize the locking effect. Through the knob screw 2221, the insertion and locking process of the optical fiber bundle 30 becomes more convenient. The user only needs to insert the optical fiber bundle 30 into the interface channel 2211 and push it to make it contact with the knob of the knob screw 2221, and then use the elasticity of the knob and the guidance of the arc-shaped groove to easily realize the locking, thereby improving the assembly efficiency of the optical fiber bundle 30. Through the adjustable locking depth of the knob screw 2221, the degree of locking of the optical fiber bundle 30 can be accurately controlled, so that the plugging process of the optical fiber bundle 30 can be optimized as needed, neither too tight to cause plugging difficulty, nor too loose to cause unstable connection. The appropriate locking depth can provide smooth and stable plugging experience, reduce the plugging resistance or shaking caused by improper locking, thereby improving the operation efficiency and use comfort.

[0048] Further, the light emitting unit 21 of the embodiment further comprises a proximity switch 212, which is configured to control the light emitting unit 21 to start working when the proximity switch 212 detects that the distance between the proximity switch 212 and the optical fiber bundle 30 is less than a preset distance. Referring to Figure 7 As shown, one end of the proximity switch 212 is arranged inside the light source interface 211 of the light emitting unit 21, and the other end is exposed outside the light emitting unit 21. When the proximity switch 212 detects that the optical fiber bundle 30 is close and the distance is less than the preset distance, the light emitting unit 21 is controlled to start working through the proximity switch 212 to make the light emitting unit 21 emit corresponding light sources. The light source types of the light emitting unit 21 of the embodiment include at least two types, for example, white light combined with fluorescence, at least one of red light, green light, blue light, ultraviolet light or amber light combined with fluorescence. The preset distance can be determined according to the light source type, the type of the light source interface assembly 22 and the type of the optical fiber bundle 30. Referring to Figure 3 As shown in Figure 6 As shown, the end of the light emitting unit 21 close to the light source interface assembly 22 is detachably provided with a mounting member 213, wherein the light source interface 211 is arranged in the mounting member.

[0049] The embodiment realizes intelligent control of the light emitting unit 21 by introducing the proximity switch 212. When the optical fiber bundle 30 is close to the preset distance from the proximity switch 212, the proximity switch 212 controls the light emitting unit 21 to start working without manual intervention, improving the convenience and efficiency of operation. That is, it is ensured that the light emitting unit 21 will only work and emit light when the optical fiber bundle 30 is inserted into the interface channel 2211 and reaches a specific position, avoiding unnecessary energy consumption and achieving the effect of energy saving and environmental protection. By setting various light source type configurations, the endoscopic illumination requirements in different scenes can be met, improving the illumination effect and quality of the endoscope.

[0050] Further, the light source module 20 further comprises at least one heat dissipation assembly 23, the heat dissipation assembly 23 is fixedly installed on the light emitting unit 21, the heat dissipation assembly 23 comprises heat dissipation fins 231 and a fan assembly 232, the heat dissipation fins 231 are fixedly installed on the outer side of the light emitting unit 21, and the fan assembly 232 is located on the side of the heat dissipation fins 231 away from the light emitting unit 21. The height, thickness and spacing parameters of the heat dissipation fins 231 of the embodiment are selected according to the heat consumption of the light emitting unit 21, and the model of the fan assembly 232 is selected according to the parameters such as air outlet direction, air volume and static pressure.

[0051] The embodiment can effectively conduct the heat generated by the light emitting unit 21 out by setting the heat dissipation assembly 23 on the light source module 20. The height, thickness and spacing parameters of the heat dissipation fins 231 are selected according to the heat consumption of the light emitting unit 21, so as to maximize the heat dissipation effect. The model of the fan assembly 232 is selected according to the parameters such as air outlet direction, air volume and static pressure, so as to ensure that the fan assembly 232 can effectively cooperate with the heat dissipation fins 231 for heat dissipation. The addition of the heat dissipation assembly 23 effectively reduces the working temperature of the light emitting unit 21, prevents problems such as decrease of light emitting efficiency, deterioration of color stability and shortening of service life caused by excessively high temperature, and reduces thermal stress generated inside the light emitting unit 21 due to temperature difference, thereby improving the reliability and stability of the light emitting unit 21.
