The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

It should be understood that fig. 1 to 11 in the present specification illustrate a schematic example of an endoscope including an illumination device, an imaging device, and a holder, and fig. 1 to 11 in the present specification illustrate the endoscope as a whole, and the holder according to the embodiment of the present application and the illumination device according to the embodiment of the present application can be understood by referring to fig. 1 to 11 in the present specification.

The holder according to the embodiment of the present application is suitable for an endoscope, and is configured to be disposed at a probe end (or referred to as a distal end) of the endoscope, and a light emitting element of an illumination device and an image pickup element of an image pickup device are mounted on the holder, so that illumination light is projected through the light emitting element to illuminate an object, and illumination light reflected from the object is collected through the image pickup element to further obtain an image of the object.

Referring to fig. 1 to 5 together, an embodiment of the present invention provides a bracket, including a main body 1, the main body 1 having a first end surface 100 and a second end surface 101 opposite to each other, the main body 1 being provided with a first mounting hole 10, the first mounting hole 10 penetrating the first end surface 100 of the main body 1, the main body 1 being provided with a second mounting hole 11 at an outer periphery of the first mounting hole 10, one end of the second mounting hole 11 penetrating the first end surface 100, and the other end of the second mounting hole 11 extending toward the second end surface 101, the main body 1 being further provided with a guide groove 12, one end of the guide groove 12 penetrating the second end surface 101, the other end of the guide groove 12 extending toward the first end surface 101 and communicating with the second mounting hole 11, and the main body 1 being formed with a light-transmitting portion 102 in a lateral direction of the second mounting hole 11.

The first mounting hole 10 is used for mounting the camera element 2, and the camera element 2 is used for collecting the illumination light reflected by the object in the front area and the side area of the bracket so as to obtain the image of the object; the second mounting hole 11 is used for mounting the light emitting element 30 of the lighting device 3, the light emitting element 30 is used for emitting light in a forward direction and a lateral direction, the forward light is projected to the front through the first end face 100 to illuminate objects in a forward area, and the lateral light is projected to the side through the light transmitting part 102 to illuminate objects in a lateral area; the guide groove 12 is used for mounting a first light guide element 31 of the lighting device 3, and the first light guide element 31 is used for guiding the light source light emitted from the light source 32 to the light emitting element 30. In the present embodiment, by providing the light-transmitting portion 102 around the second mounting hole 11 of the holder, not only the light emitting element 30 can be held, but also the light emitted in the lateral direction can be emitted toward the lateral region, and the light emitting region of the illumination light of the illumination device of the endoscope can be expanded.

The body 1 may be selected to be a columnar structure extending along its length, and its cross-sectional shape is circular. The light-transmitting portion 102 may be formed in an annular structure. The main body 1 and the light-transmitting portion 102 may be selected to be an integral member, for example, in molding, a light-transmitting material may be molded in a region of the light-transmitting portion 102, or the main body 1 and the light-transmitting portion 102 may be selected to be separate members, and the light-transmitting portion 102 may be fixed to the main body 1 by, for example, adhesion. When main body 1 and light-transmitting portion 102 are separate members, first end surface 100 is referred to as an end surface of light-transmitting portion 102 facing in the forward direction. In other examples, the main body 1 may also be selected to have other cross-sectional shapes, such as regular shapes like an ellipse, a polygon, etc., or similar irregular shapes, and the light-transmitting portion 102 may be selected to have the same outer contour shape as the main body 1 or a different outer contour shape, which is not limited in this application.

The body 1 has a shroud 13 formed around the first mounting hole 10, and the translucent portion 102 is fitted over the shroud 13. The inner portion of the enclosing plate 13 encloses at least a portion of the first mounting hole 10, the enclosing plate 13 can provide positioning for the light-transmitting portion 102, and ensure that the position of the light-transmitting portion 102 in the radial direction of the main body 1 is accurate, and the enclosing plate 13 can be made of a light-proof material, so that light emitted from the light-emitting element 30 in the second mounting hole 11 can be prevented from entering the first mounting hole 10 through the light-transmitting portion 102.

According to some embodiments of the present application, the first mounting hole 10 may be provided at the center of the main body 1, i.e., the central axis of the first mounting hole 10 coincides with the central axis of the main body 1. In other embodiments, the first mounting hole 10 may be eccentrically disposed on the main body 1, i.e. the central axis of the first mounting hole 10 is not coincident with the central axis of the main body 1.

Considering that the second mounting hole 11 is located at the periphery of the first mounting hole 10, a part of light rays emitted from the inside of the first mounting hole 10 and emitted toward the lateral direction through the light-transmitting portion 102 is blocked by the surrounding plate 13 outside the first mounting hole 10, so that a blind area occurs in the lateral region of the bracket. In order to reduce the size of the blind area, it is possible to increase the distance between the first mounting hole 10 and the second mounting hole 11 as much as possible. For this reason, in some embodiments of the present application, the first mounting hole 10 is eccentrically disposed on the main body 1, and the central axis of the first mounting hole 10 and the central axis of the second mounting hole 11 are located at both sides of the central axis of the main body 1, respectively.

Referring to fig. 6a to 6c, in the embodiment of the present application, the number of the second mounting holes 11 may be selected to be one or more. When the number of the second mounting holes 11 is one, the second mounting holes 11 may be located at any position around the first mounting holes 10; when the number of the second mounting holes 11 is plural, the second mounting holes 11 may be uniformly arranged around the first mounting holes 10. For example, in one example, the number of the second mounting holes 11 is two, and two second mounting holes 11 are uniformly arranged around the first mounting hole 11, and the circumferential angle between the two second mounting holes 11 is 180 degrees. It is to be noted that when the number of the second mounting holes 11 is plural, even if the first mounting hole 10 is arranged at the center position of the main body 1, the occurrence of the surface dead zone is possible.

According to some embodiments of the present application, as shown in fig. 4, 5 and 7, the guide groove 12 is formed with an opening upward at a side of the main body 1. The main body 1 is generally configured as an elongated main body, and the length of the first light guiding element 31 is relatively long, so that the first light guiding element 31 is inserted into the guide groove 12 from the side through the opening, which significantly reduces the difficulty of installing the first light guiding element 31. Further, the first light guiding element 31 mounted in the guide groove 12 can be fixed in the guide groove 12 by means of dispensing, for example, dispensing is performed at a plurality of positions in the longitudinal direction of the guide groove 12, which is convenient to process and has good mounting reliability.

Specifically, the guide groove 12 may be selected to be a V-groove. In the direction of the opening of the guide groove 12, the cross-sectional area gradually increases, i.e., the size of the opening is large, the size of the interior is small, the first light guide element 31 can be guided, and the opening can have a sufficient space for the dispensing operation.

The outer surface of the main body 1 is further provided with a housing 103, the housing 103 is slidably disposed on the main body 1 along the length direction of the main body 1, and the housing 103 is used for closing the opening of the guide groove 12 after the first light guiding element 31 is installed, so as to protect the elements inside the guide groove 12. The housing 103 may be selected to be a metal housing to ensure sufficient strength. Specifically, for example, when the light guide element 31 is mounted, the housing 103 is slid such that the position of the housing 103 on the main body 1 is moved above or below the guide groove 12 to expose the guide groove 12, thereby facilitating the mounting of the light guide element 31 into the guide groove 12, and after the light guide element 31 is mounted into the guide groove 12, the housing 103 is slid such that the housing 103 covers the outside of the guide groove 12, thereby serving to protect the light guide element 31 in the guide groove 12.

According to some embodiments of the present application, the main body 1 is further provided with a guide hole 14, the guide hole 14 is disposed between the second mounting hole 11 and the guide groove 12, and both ends of the guide hole 14 are connected to the second mounting hole 11 and the guide groove 12, respectively.

The first light guide element 31 disposed in the guide groove 12 is generally small in size, and directly adopting the form of coupling the first light guide element 31 and the light emitting element 30 may cause that the area of the light emitting element 30 adjacent to the first light guide element 31 cannot receive the light beam, in the embodiment of the present application, the second guide element 32 is disposed in the guide hole 14, and the size of the second guide element 32 may be equal to or approximately equal to the size of the light emitting element 30, so as to ensure the utilization rate of the light emitting element 30. To this end, in an alternative embodiment of the present application, the size of the guide hole 14 is equal or substantially equal to the size of the second mounting hole 11.

Referring to fig. 8 to 11, the stand of the embodiment of the present application further includes a light directing element 4, and the light directing element 4 is located in front of the main body 1 and has one end fixed to the main body 1. The light directing element 4 is capable of receiving illumination light reflected from an object in a lateral direction of the rack 1 and directing the illumination light to the first mounting hole 10. The light directing element 4 may alternatively be a mirror, and the mirror is arranged obliquely in front of the body 1, the angle of inclination of the mirror being, for example, 45 degrees. In other embodiments, the light directing element 4 may alternatively be a convex mirror or a prism arranged obliquely in front of the body 1.

The bracket of the embodiment of the application further comprises a shielding piece 5, wherein the shielding piece 5 is arranged on the light-transmitting part 102 between the first mounting hole 10 and the second mounting hole 11 and shields a part of the forward area of the second mounting hole 11. When the light guide device is applied to an endoscope, the light guide element 4 is positioned in front of the main body 1, part of illumination light emitted towards the forward direction directly enters the light guide element 4 and is guided by the light guide element 4 to directly enter the image pickup element 2, the brightness of the part of light beams is too high, the central area of the obtained image is easily subjected to overexposure, the part of light beams directly entering the light guide element 4 can be shielded by the shielding sheet 5, and therefore the problem that the image collected by the image pickup element 2 is locally subjected to overexposure is avoided.

The lighting device according to the embodiment of the present application is described in detail below, and it should be noted that when the bracket according to the embodiment of the present application is described above, the lighting device has been briefly described, so that when the lighting device according to the embodiment of the present application is described below, relevant portions may be referred to each other.

It should be noted that the illumination device according to the embodiment of the present application is mainly applied to an endoscope to actively illuminate a region to be detected, and then an image of the region to be detected is captured by an image capturing device of the endoscope. Of course, the lighting device of the embodiment of the present application may also be applied to other active lighting scenes, such as a car headlight, a spot light, a stage light, a searchlight, a street lamp, or other active lighting devices for actively illuminating a target area.

Usually, the wavelength conversion layer is limited by conversion efficiency, and cannot convert all the excitation light into excited light, so that the light beam emitted through the wavelength conversion layer includes both excited light and unexcited excitation light, wherein the excited light and the unexcited excitation light are mixed to form illumination light, and because the excitation light and the excited light have different wavelengths, the illumination light formed by mixing the excited light and the excited light can be white light. The wavelength conversion layer is, for example, a dielectric layer containing a fluorescent material.

The first light guiding element 31 is for example an optical fibre. When the light source 33 is provided as a laser diode, the optical fiber may be a single optical fiber, which can significantly reduce the size of the entire lighting device.

The size of the second light guiding element 32 is equal or approximately equal to the size of the light exiting element 30 to ensure that the light source light exiting through the second light guiding element 32 can substantially cover the side area of the light exiting element 30.

Specifically, the second light guide element 32 and the light exit element 30 can be formed on the same light guide rod. That is, the wavelength conversion layer is provided at the end region of the light guide rod, so that the front stage of the light guide rod forms the second light guide element 32 and the rear stage of the light guide rod forms the light exit element 30.
