Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.
As Figure 1-3, otoscope involved by this utility model comprises otoscope main body 1, described otoscope main body 1 inside is cavity, form otoscope cavity 9, endoscope 2 is plugged in described otoscope cavity 9, and the front end of described endoscope 2 is plugged on otoscope cavity front end area 91, to reach observing effect better; The rearward end of described endoscope 2 is provided with the cold light source union joint 4 be connected with the luminous source optical fiber passage 22 in endoscope 2, and for connecting outside cold light source, outside cold light source provides illumination through described luminous source optical fiber passage 22 for performing the operation; The front end of described endoscope 2 is provided with composition lens 21, its rear end is provided with image documentation equipment union joint 8, described image documentation equipment union joint 8 is connected with outside image documentation equipment, described composition lens 21 is connected to the image system in outside image documentation equipment by video transmission channels 211, the image at wound surface place is presented on image documentation equipment in real time, doctor is facilitated to observe; Described endoscope 2 is when being plugged in described otoscope cavity 9, and the angle of the axis of described endoscope 2 video transmission channels 211 and the horizontal axis of described otoscope cavity 9 is 2 ~ 3 °.Concave mirror 11 is provided with successively along swashing on light-struck direction in described otoscope cavity 9, lens 5 and reflecting mirror 6, wherein said concave mirror 11 and lens 5 be arranged in parallel, described reflecting mirror 6 is 30 ~ 60 degree of angles with described lens 5 and is arranged in the otoscope main body 1 below described lens 5, described reflecting mirror 6 and described endoscope 2 split the both sides of the horizontal axis at described otoscope cavity 9, the angle of the laser beam reflected through described reflecting mirror 6 and the horizontal axis of described otoscope cavity 9 is 2 ~ 3 °, the axis of laser beam and described endoscope 2 video transmission channels 211 reflected through described reflecting mirror 6 is namely made to converge in wound surface place, and be the angle of 4 ~ 6 degree, be wherein best with 5 °, outside described otoscope main body 1, be provided with focusing ring 12, described focusing ring 12 is connected with described concave mirror 11, otoscope main body 1 above described concave mirror 11 is provided with light-conducting arm union joint 7, described light-conducting arm union joint 7 for the light-conducting arm of external carbon dioxide laser therapeutic apparatus, to make laser be irradiated to described concave mirror 11 through light-conducting arm union joint 7.
