[0054] The above drawings have shown clear embodiments of the present application, which will be described in more detail later.

DETAILED DESCRIPTION

[0055] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0056] An endoscope is a detection instrument that includes a camera device, a light source device, and a display device. It is one of the important surgical instruments in minimally invasive surgery. During the use of the endoscope, the doctor can insert the endoscope into the patient's abdominal cavity, allow the endoscope to reach the lesion location, and use the light source device for illumination. The image sensor in the display device is then used to capture images, and the captured images are transmitted to the display device for display, so that the doctor can observe the lesion in real time.

[0057] The light source device can emit white light and laser, so that the endoscope can obtain visible light images and images of other bands besides visible light (such as near-infrared light images), which can improve the efficiency and accuracy of diagnosis. Since the light source device has a high illumination when turned on, direct exposure to the human eye will cause interference or harm to the user.

[0058] In the related art, when the endoscope light source device is in use, there is a risk that when the light guide beam is not plugged into the light source host, the light source host still emits light, causing the laser to cause damage to the human eye or other tissues, resulting in low safety of the endoscope light source device.

[0059] The embodiments of the present application provide an endoscope light source device and an endoscope system, which can solve the problems existing in the above-mentioned related technologies.

[0060] Figure 1 is a structural schematic diagram of an endoscope light source device 10 provided in an embodiment of the present application, Figure 2 1 is a schematic diagram of an exploded structure of an endoscope light source device 10 provided in an embodiment of the present application. Figure 3 is looking along the first direction f1 Figure 1 The structural schematic diagram of the endoscope light source device 10 is shown in FIG. Figure 4 yes Figure 3 The endoscope light source device 10 is a schematic cross-sectional structure diagram along the position A1-A2, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the endoscope light source device 10 may include: a light source host 11, a detection component 12 and a light guide 13. The light source host 11 may be used to provide an illumination light source. The light source host 11 may include a housing 111, a plug-in barrel 112 and a light source component 113 located in the housing 111. Exemplarily, the light source component 113 may include a laser light source and a white light source, the housing 111 may be a cubic box, the housing 111 may have a cavity, and the laser light source, the white light source, the plug-in barrel 112 and the detection component 12 may all be located in the cavity of the housing 111.

[0061] The plug-in barrel 112 may have a receiving cavity q1, and the light guide 13 may be connected to the light source assembly 113 by being inserted into the receiving cavity q1 inside the plug-in barrel 112. One end of the plug-in barrel 112 is connected to the light outlet of the light source assembly 113, and the light guide 13 may be connected to the light source assembly 113 by being inserted into the plug-in barrel 112. Figure 1 In the endoscope light source device 10 shown, at least part of the light guide 13 is located inside the light source host 11, that is, the light guide 13 is inserted into the plug-in tube 112 of the light source host 11. The housing 111 of the light source host 11 may include a top plate and a bottom plate opposite to each other, the bottom plate may be located on a side of the top plate close to the ground, and the first direction f1 may be a direction perpendicular to the plate surface of the top plate.

[0062] Figure 5 is a schematic structural diagram of another endoscope light source device 10 provided in an embodiment of the present application. Figure 6 yes Figure 5 The endoscope light source device 10 is a schematic cross-sectional structure diagram along the position B1-B2, please refer to Figure 5 and Figure 6 , Figure 6 The triggering portion 1212 of the rotating structure 121 shown in FIG. 1 is located at a first position, Figure 4 The triggering portion 1212 of the rotating structure 121 shown in FIG. 1 is located at the triggering position of the detection switch 122 . Figure 5 In the endoscope light source device 10 shown, the light guide 13 is located outside the light source host 11, that is, the light guide 13 has not been inserted into the plug-in barrel 112 of the light source host 11. The detection assembly 12 may include a rotating structure 121 and a detection switch 122. The plug-in barrel 112 may have a mounting through hole k1 on its wall. At least part of the rotating structure 121 may be located in the mounting through hole k1. The detection switch 122 may be located outside the mounting through hole k1. The detection switch 122 may be electrically connected to the light source assembly 113. The extension direction of the mounting through hole k1 may be perpendicular to the extension direction of the accommodating cavity q1 inside the plug-in barrel 112. One end of the mounting through hole k1 may be connected to the inside of the plug-in barrel 112, and the other end of the mounting through hole k1 may be connected to the outside of the plug-in barrel 112. The rotating structure 121 can be installed in the installation through hole k1, so that the rotating structure 121 can contact the light guide 13 located inside the plug-in barrel 112, and can also trigger the detection switch 122 located outside the installation through hole k1 (that is, outside the plug-in barrel 112). The detection switch 122 can be used to control the opening and closing of the light source assembly 113.

[0063] The rotating structure 121 may include a connected rotating part 1211 and a triggering part 1212, one end of the triggering part 1212 may be located outside the mounting through hole k1, the rotating part 1211 may be rotatably connected to the plug-in barrel 112, and may drive the triggering part 1212 to rotate between the first position and the triggering position of the detection switch 122 when rotating, and when the triggering part 1212 is in the first position, one end of the rotating part 1211 may be located inside the plug-in barrel 112. That is, when one end of the rotating part 1211 is located inside the plug-in barrel 112, the triggering part 1212 is located in the first position, and at this time, although one end of the triggering part 1212 is located outside the mounting through hole k1, the triggering part 1212 and the detection switch 122 do not affect each other.

[0064] When the light guide 13 is inserted into the plug-in barrel 112, the light guide 13 can push the rotating part 1211 out of the plug-in barrel 112. At this time, one end of the rotating part 1211 is located outside the plug-in barrel 112 and in the mounting through hole k1. Since the rotating part 1211 can drive the trigger part 1212 to rotate between the first position and the trigger position of the detection switch 122 when rotating, the rotating part 1211 rotating from the inside of the plug-in barrel 112 to the outside of the plug-in barrel 112 can drive the trigger part 1212 to rotate from the first position to the trigger position of the detection switch 122, so as to turn on the light source assembly 113 through the detection switch 122. In this way, the detection assembly 12 can obtain the insertion state of the light guide 13 through the rotating part 1211, and trigger the detection switch 122 through the trigger part 1212, so as to turn on the light source assembly 113 after the light guide 13 is inserted into the plug-in barrel 112. The phenomenon that the light source host 11 emits light when the light guide beam 13 is not plugged into the light source host 11 can be avoided, thereby improving the safety of the endoscope light source device 10.

[0065] It should be noted that, in the embodiment of the present application, the inside of the plug-in barrel 112 refers to the space where the accommodating cavity q1 inside the plug-in barrel 112 is located, and does not include the space inside the installation through hole k1.

[0066] In summary, the embodiment of the present application provides an endoscope light source device including a light source host, a detection component and a light guide. Among them, the light source host includes a plug-in tube and a light source component, the detection component includes a rotating structure and a detection switch, and the detection switch and the light source component are electrically connected. The rotating structure includes a connected rotating part and a triggering part, the rotating part is rotatably connected to the plug-in tube, the rotating part can drive the triggering part to rotate between a first position and a triggering position of the detection switch when rotating, and one end of the rotating part can be located inside the plug-in tube. In this way, the detection component can obtain the insertion state of the light guide through the rotating part, and drive the triggering part to trigger the detection switch through the rotating part, so as to turn on the light source assembly after the light guide is inserted into the plug-in tube. The phenomenon that the light source host emits light when the light guide is not plugged into the light source host can be avoided, and the problem of low safety of the endoscope light source device in the related art can be solved, thereby achieving the effect of improving the safety of the endoscope light source device.

[0067] Figure 7 1 is a schematic diagram of a structure of a rotating structure 121 and a plug-in tube 112 provided in an embodiment of the present application. Figure 8 yes Figure 7 For an exploded schematic diagram of the rotating structure 121 and the plug-in tube 112, please refer to Figure 7 and Figure 8 In an optional embodiment, the rotating structure 121 may further include a rotating shaft 1213, which may be located in the mounting through hole k1 and may be rotatably connected to the plug-in barrel 112. The hole wall of the mounting through hole k1 may have two opposite first through holes k2. In other words, the two first through holes k2 are also located on the barrel wall of the plug-in barrel 112, and the extension direction of the first through holes k2 may be perpendicular to the extension direction of the mounting through hole k1. There is a fitting clearance between the rotating shaft 1213 and the first through hole k2, and the fitting clearance may be less than 0.1 millimeters (mm), so that the rotating shaft 1213 can rotate in the first through hole k2, thereby making the rotating shaft 1213 and the plug-in barrel 112 rotatably connected.

[0068] The rotating part 1211 may include a connected bearing member z1 and a first rotating arm z2, the bearing member z1 may have a connecting through hole k3, and at least a portion of the rotating shaft 1213 may be located in the connecting through hole k3. The two ends of the rotating shaft 1213 may be located in the two first through holes k2 respectively, and the middle portion of the rotating shaft 1213 may be inserted into the connecting through hole k3 of the bearing member z1, so that the rotating part 1211 and the plug-in tube 112 can be rotatably connected by the rotating shaft 1213 and the plug-in tube 112, thereby realizing the rotatable connection between the rotating part 1211 and the plug-in tube 112. Among them, the bearing member z1 and the first rotating arm z2 may be an integrated structure to improve the strength and stability of the rotating part 1211.

[0069] The rotating shaft 1213 can be movably connected to at least one of the first through hole k2 and the connecting through hole k3, so as to realize the rotatable connection between the rotating shaft 1213 and at least one of the plug-in barrel 112 and the rotating portion 1211. In an exemplary embodiment, there is a matching clearance between the rotating shaft 1213 and the connecting through hole k3, and the matching clearance can be less than 0.1 millimeters (mm), so that the rotating shaft 1213 can rotate in the connecting through hole k3, so that the flexibility of the movably connected rotating portion 1211 and the plug-in barrel 112 can be further improved.

[0070] The triggering part 1212 may include a second rotating arm z3, the second rotating arm z3 may be connected to the bearing member z1, and the length direction of the second rotating arm z3 may intersect with the length direction of the first rotating arm z2. Further, the length direction of the second rotating arm z3 may be perpendicular to the length direction of the first rotating arm z2, so that the rotating structure 121 may be an L-shaped structure, which may make the size of the rotating structure 121 more compact.

[0071] Please refer to Figure 2 , Figure 4 and Figure 6 In an optional embodiment, the detection assembly 12 may further include a mounting bracket 123 and an elastic reset member 124. The mounting bracket 123 may be located outside the mounting through hole k1, and the mounting bracket 123 may be fixedly connected to the plug-in barrel 112. The elastic reset member 124 may be located between the mounting bracket 123 and the rotating portion 1211, one end of the elastic reset member 124 may be connected to the mounting bracket 123, and the other end of the elastic reset member 124 may abut against the end of the first rotating arm z2 away from the bearing member z1.

[0072] The elastic reset member 124 can be located in the mounting through hole k1 of the plug-in barrel 112, and contact the outer side of the first rotating arm z2 facing the mounting through hole k1 (the outer side of the end of the mounting through hole k1 away from the inside of the plug-in hole). In this way, when the light guide 13 is not inserted into the plug-in barrel 112, or the light guide 13 is pulled out of the plug-in barrel 112, the elastic reset member 124 can push one end of the first rotating arm z2 from the mounting through hole k1 to the inside of the plug-in barrel 112, so as to drive the triggering part 1212 to be located at the first position.

[0073] Fig. 9 1 is a schematic diagram of an exploded structure of another plug-in tube 112, a detection assembly 12 and a light guide 13 provided in an embodiment of the present application. Fig.10 This is a schematic diagram of the structure of a mounting bracket 123 and an elastic reset member 124 provided in an embodiment of the present application. Please refer to Fig. 9 and Fig.10In an optional embodiment, the elastic reset member 124 may include a spring 1241. When the light guide 13 is inserted into the plug-in barrel 112, the light guide 13 pushes the first rotating arm z2 out of the plug-in barrel 112, and the spring 1241 may be in a contracted state. When the light guide 13 is pulled out of the plug-in barrel 112, the spring 1241 may push the end of the first rotating arm z2 toward the inside of the plug-in barrel 112, so as to drive the triggering portion 1212 to rotate from the triggering position to the first position.

[0074] The mounting bracket 123 may include a connected support portion 1231 and a spring mounting portion 1232. The spring mounting portion 1232 may be located on a side of the support portion 1231 close to the mounting through hole k1. The spring 1241 may be mounted in the spring mounting portion 1232. The spring mounting portion 1232 may be a cylindrical structure to facilitate limiting the spring 1241 to prevent the spring 1241 from bending during extension and retraction. Furthermore, one end of the spring 1241 close to the first rotating arm z2 may extend out of the spring mounting portion 1232 to facilitate extension and retraction of the spring 1241 under the push of the first rotating arm z2.

[0075] The support portion 1231 of the mounting bracket 123 can be fixedly connected to the plug-in tube 112. Exemplarily, the endoscope light source device 10 may include a first bolt (not shown in the figure), and the outer side of the tube wall of the plug-in tube 112 may have a first mounting hole k4. The support portion 1231 of the mounting bracket 123 may have a second mounting hole k5 corresponding to the first mounting hole k4. The first bolt may be located in the first mounting hole k4 and the second mounting hole k5 to connect the support portion 1231 of the mounting bracket 123 and the plug-in tube 112, and realize the positioning and assembly of the mounting bracket 123 and the plug-in tube 112.

[0076] Please refer to Figure 4 and Figure 6 At least part of the second rotating arm z3 and at least part of the spring mounting portion 1232 can be located in the mounting through hole k1. When the second rotating arm z3 is in the first position, the end of the second rotating arm z3 away from the supporting member z1 can abut against the spring mounting portion 1232. When the second rotating arm z3 is in the trigger position of the detection switch 122, the side of the second rotating arm z3 away from the spring mounting portion 1232 can abut against the side wall of the mounting through hole k1. In this way, the rotation angle of the rotating part 1211 can be limited by the spring mounting portion 1232 in the mounting bracket 123 and the hole wall of the mounting through hole k1 on the plug-in cylinder 112 to prevent the rotating angle of the rotating part 1211 from being too large.

[0077] In an exemplary embodiment, when the spring 1241 is installed between the mounting bracket 123 and the rotating structure 121, the spring 1241 can be pre-compressed and assembled between the mounting bracket 123 and the rotating structure 121, that is, the spring 1241 can have a first contraction state and a second contraction state, and the compression degree of the spring 1241 in the second contraction state is greater. When the light guide 13 is not inserted into the plug-in barrel 112, or the light guide 13 is pulled out of the plug-in barrel 112, the spring 1241 can push one end of the first rotating arm z2 from the mounting through hole k1 to the inside of the plug-in barrel 112 to drive the trigger part 1212 to be located at the first position. At this time, the spring 1241 can be in the first contraction state, that is, at this time, the spring 1241 can still apply pressure toward the inside of the plug-in barrel 112 to the first rotating arm z2 in the rotating structure 121 to fix the rotating structure 121 at the current position, which can improve the stability of the rotating structure 121. When the light guide 13 is inserted into the plug-in cylinder 112 , the light guide 13 can push the first rotating arm z2 of the rotating structure 121 out of the plug-in cylinder 112 , the first rotating arm z2 can be located in the mounting through hole k1 , and the spring 1241 can be compressed to the second contracted state.

[0078] In this way, under the action of the spring 1241, the rotating structure 121 has a tendency to always rotate clockwise around the rotating axis 1213. This allows the triggering portion 1212 of the rotating structure 121 to be in the first position when the light guide beam 13 is not inserted, and the detection switch 122 is not triggered. When the light guide beam 13 is inserted into the plug-in tube 112, the rotating structure 121 gradually rotates counterclockwise under the squeezing of the light guide beam 13 until the light guide beam 13 is inserted into place. At this time, the triggering portion 1212 of the rotating structure 121 reaches the triggering position of the detection switch 122, and the triggering portion 1212 triggers the detection switch 122 to turn on the light source assembly 113. When the light guide beam 13 is pulled out, the rotating structure 121 rotates counterclockwise again under the action of the spring 1241, and the triggering portion 1212 moves to the first position, and the detection switch 122 turns off the light source assembly 113. It should be noted that the clockwise direction refers to Fig. 9 and Fig.10 In the clockwise direction of the orientation shown in , the light guide 13 has a light guide 13 connector. In the embodiment of the present application, the portion of the light guide 13 inserted into the plug-in tube 112 can be the light guide 13 connector.

In this way, in the process of pulling the light guide 13 out of the plug-in slot, when the light guide 13 is pulled out to the position of the oblique side wall t11 of the protruding structure t1 of the first rotating arm z2, the rotating structure 121 can be rotated toward the inside of the plug-in tube 112 to a large extent under the action of the oblique side wall t11, so that the trigger part 1212 in the rotating structure 121 can leave the trigger position of the detection switch 122 in advance, so as to quickly turn off the light source assembly 113 through the detection switch 122.

The rotating part 1211 can drive the trigger part 1212 to rotate from the trigger position of the detection switch 122 to the first position during rotation.

Please refer to Fig.17 In an optional embodiment, the rotating part 1211 may also include a reset counterweight z5, and the reset counterweight z5 may be fixedly connected to the end of the first rotating arm z2 away from the bearing member z1.

The reset counterweight z5 can be used to increase the weight of the first rotating arm z2, so that under the action of the reset counterweight z5, the rotating structure 121 has a tendency to always rotate around the rotating axis 1213 toward the inside of the plug-in barrel 112. When the light guide 13 is inserted into the plug-in barrel 112 again, the rotating structure 121 can obtain the insertion status of the light guide 13 in time, avoiding the situation that the rotating structure 121 is still completely located in the mounting through hole k1 after the light guide 13 is pulled out of the plug-in barrel 112, which can improve the accuracy of the detection component 12.
