Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
The application is described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and fig. 2, a tube 100 according to an embodiment of the application includes a tube body 110, a light acting member 130 and an illumination module 120, wherein the tube body 110 has a first end 112 and a second end 113, the tube body 110 defines a light channel 114 extending to the first end 112 and the second end 113 along a length direction thereof, and a light acting surface (not shown) is disposed inside the light channel 114. The light acting element 130 is disposed at the first end 112, where the light acting element 130 is configured to propagate the reflected light of the portion to be detected to a light acting surface, and the light acting surface is configured to propagate the received light along the light channel 114 to a light outlet of the light channel 114 at the second end 113, so as to be acquired by the external image collector 200; the illumination module 120 is disposed at the first end 112 for illuminating the portion to be detected.
The cross section of the light channel 114 is rectangular, but is not limited to rectangular, for example, the light channel 114 may be circular or other shapes.
Specifically, when the video laryngoscope acquires an image of the patient's throat, the first end 112 of the viewing tube body 110 extends into the vicinity of the patient's epiglottis, and at the same time, the illumination module 120 illuminates the portion to be detected, and the reflected light of the portion to be detected propagates to the light acting element 130. The light acting element 130 propagates the acquired light to the light acting surface of the light channel 114, where the light acting surface is configured to propagate the received light along the light channel 114 until the light propagates to the light outlet of the light channel 114, where the light outlet forms an opening at the second end 113 of the light channel 114. At this time, the external image collector 200 receives the light transmitted from the light channel 114 and processes the light to obtain image information of the patient's throat, and the display screen 320 of the display 300 displays the image of the patient's throat according to the image information.
It can be understood that, instead of providing a miniature camera at the front end of the video laryngoscope, the video laryngoscope of the application adopts the above-mentioned video tube 100, and the video tube 100 is matched with the light action surface through the light action member 130, so that the reflected light of the portion to be detected propagates to the external image collector 200 along the light channel 114, thereby obtaining the image information of the throat of the patient. Because the image collector 200 does not need to be applied in the oral cavity of the patient, the size of the oral cavity of the patient does not need to be considered when the image collector 200 is selected, the image collector 200 can use a chip with large size and higher image perception, optical zooming can also be realized, and the functionality and imaging quality of image collection are greatly improved from the hardware.
In addition, the image collector 200 at least includes an image collecting module 250 and an image processing module 260 (refer to fig. 7), the image collecting module 250 is configured to obtain reflected light of the portion to be detected, and the image processing module 260 processes the obtained reflected light to obtain image information. The image processing module 260 is disposed at the first end 112 to directly obtain the reflected light of the portion to be detected, and then is transmitted to the outside through the wire harness. In the present application, the image capturing module 250 is disposed at a position corresponding to the second end 113, for example, the image capturing module 250 may be mounted in a handle of a video laryngoscope (the handle may be understood as a housing 210 described below), and the image processing module 260 is generally disposed in the handle, so that a lengthy wire harness is not required to be designed between the image capturing module 250 and the image processing module 260, which can reduce the influence of electromagnetic interference on the image signal, thereby making the image quality cleaner.
In addition, compared with the image acquisition module 250 mounted on the first end 112, the image acquisition module 250 in the embodiment of the application is disposed at a position corresponding to the second end 113, for example, mounted on the inner side of the handle, so that the image acquisition module 250 has higher safety and is not easy to damage, and the service life of the video laryngoscope 400 is ensured.
In order to achieve the transmission of the reflected light of the portion to be detected along the optical channel 114, various modes may be adopted, and the following modes are described, but the present application is not limited to the following modes.
In one possible embodiment, the light-influencing surface is configured to continuously reflect received light along the light channel 114, such that the light can propagate along the light channel 114 to the light-exit of the light channel 114. In a specific implementation, the light acting element 130 propagates the reflected light of the portion to be detected to a position near the light inlet of the light channel 114, and is located on the light acting surface. The light is continuously reflected along the light channel 114 by the light acting surface, and the direction of each reflection approaches toward the second end 113, so that after multiple reflections, the light propagates to the light outlet of the light channel 114 (refer to the light path in fig. 1). Thus, the external image collector 200 may receive light transmitted from the light exit of the light tunnel 114 to acquire image information of the patient's throat.
To achieve continuous reflection of light in the light channel 114, in some possible embodiments, the viewing tube body 110 is made of a reflective material, such as platinum, silver, aluminum, or the like. It will be appreciated that the tube body 110 is made of a reflective material, so that the inner wall of the tube body 110 forms the reflective surface, and the inner wall of the tube body 110 continuously reflects the received light along the light channel 114.
Instead of forming the reflective surface as described above, in some possible embodiments, referring to fig. 1 and 2, the viewing tube 100 further includes at least one reflective layer 140 or a plurality of reflective layers 140, which may be set according to actual needs. For example, one light reflecting layer 140 is disposed on the outer arc surface of the light channel 114, and the light acting surface is the inner arc surface of the light reflecting layer 140. Since the light channel 114 extends in the arc direction, the reflective layer 140 also extends in the arc direction, so that each reflection of light can reflect back to the light-acting surface (refer to the light path in fig. 1 specifically). Thus, the light is repeatedly reflected by the reflective layer 140, and the light gradually propagates along the light channel 114 to the light outlet of the light channel 114. Alternatively, two light reflecting layers 140 are provided, and two light reflecting layers 140 are disposed on opposite sides of the light channel 114, that is, one light reflecting layer 140 is disposed on an intrados surface of the light channel 114, and the other light reflecting layer 140 is disposed on an extrados surface of the light channel 114, and the sides of each light reflecting layer 140 form the light reflecting surface. Therefore, the light acting element 130 obliquely transmits the light to the light acting surface of the light reflecting layer 140 on one side, the light reflecting layer 140 obliquely reflects the light to the light acting surface of the light reflecting layer 140 on the other side, and the light reflecting layer 140 on the other side obliquely reflects the light to the previous light reflecting layer 140, so that the light gradually propagates to the light outlet of the light channel 114 along the light channel 114 under the repeated reflection of the light passing through the two light reflecting layers 140.
The reflective layer 140 may be a reflective paint, a metal layer, etc. coated on the inner wall of the optical channel 114, a reflective film adhered on the inner wall of the optical channel 114, etc., or a metal layer electroplated on the inner wall of the optical channel 114 by electrolysis, which is not described in detail.
Instead of forming the reflective surface in the above manner, in some possible embodiments, the viewing tube 100 further includes at least one output mirror or a plurality of output mirrors (not shown in the drawings, and may correspond to the reflective layer described above), which are specifically set according to actual needs. For example, one output mirror is provided, which is disposed at the outer arc surface of the light channel 114, so that the output mirror gradually reflects light to the light outlet of the light channel 114. Or, two output reflectors are provided, one is disposed on the inner arc surface of the optical channel 114, and the other is disposed on the outer arc surface of the optical channel 114, so that light is continuously reflected between the two output reflectors, thereby realizing gradual propagation along the optical channel 114 to the light outlet of the optical channel 114.
Of course, the inner wall of the optical channel 114 may be provided with the reflective layer 140 and the output mirror at the same time, and the reflective layer 140 and the output mirror cooperate to reflect the light to the light outlet of the optical channel 114 along the optical channel 114, which is not described in detail.
In another possible embodiment, the light-influencing surface is used to continuously refract the captured light along the light channel 114, so that the light propagates along the light channel 114 to the light outlet of the light channel 114. In a specific implementation, the light acting element 130 propagates the reflected light of the portion to be detected to a position near the light inlet of the light channel 114, and is located on the light acting surface. The light is continuously refracted along the light channel 114 by the light acting surface, and each refraction direction approaches toward the second end 113, so that after multiple refraction, the light propagates to the light outlet of the light channel 114 (refer to the light path in fig. 3). Thus, the external image collector 200 may receive light transmitted from the light exit of the light tunnel 114 to acquire image information of the patient's throat.
In a specific embodiment, referring to fig. 3, the viewing tube 100 further includes a plurality of first refractive lenses 150, where the plurality of first refractive lenses 150 are sequentially disposed in the light channel 114, and each of the first refractive lenses 150 forms a light application surface. In a specific implementation, the light acting element 130 propagates the reflected light of the portion to be detected to one light acting surface of the first refractive lens 150 at the initial position, and when the light propagates from the other light acting surface of the first refractive lens 150, the light is refracted to a certain extent, so that the light can propagate toward the next first refractive lens 150, and thus, after the light passes through the plurality of first refractive lenses 150, the light propagates gradually along the light channel 114 to the light outlet of the light channel 114, and therefore, the external image collector 200 can receive the light propagated from the light outlet.
Further, each of the first refractive lenses 150 is a concave mirror, and the plurality of concave mirrors cooperate to continuously refract the light propagating to the optical channel 114, so that the light can propagate along the optical channel 114 and propagate out from the light outlet of the optical channel 114. Wherein, the concave mirror can adopt a diopter lens. Alternatively, each of the first refractive lenses 150 is a convex lens, and the plurality of convex lenses cooperate to continuously refract the light propagating to the optical channel 114, so that the light can propagate along the optical channel 114 and propagate out from the light outlet of the optical channel 114.
