Medical otoscope

Abstract

A medical otoscope, comprises an otoscope body and an observation apparatus connected to one end of the otoscope body, the other end of the otoscope body having a tapered portion capable of inserting into an ear, the observation apparatus comprising at least one optical lens group arranged along a same optical axis, the optical lens group comprising at least one optical lens capable of moving along the optical axis, central axis of the observation apparatus being coaxial with or deviating from central axis of the otoscope body. The focal length of the medical otoscope can be adjusted by means of arranging two groups of optical lenses movable relative to one another, and the medical otoscope has a simple structure and is convenient for operation.

(2) FIG. 2 is a use state diagram of the embodiment;

(3) FIG. 3 is a schematic sectional view of the embodiment;

(4) wherein, 1otoscope body; 10tapered portion; 11inner cavity; 2observation apparatus; 20connecting housing; 21adjusting housing; 22first optical lens; 23second optical lens; 3ear speculum; 4illuminating apparatus.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(5) In the following, the present disclosure are described in detail combining with the accompanying drawings and embodiments.

(6) A medical otoscope as shown in the figures, comprises an otoscope body 1 and an observation apparatus 2 connected to one end of the otoscope 1, the other end of the otoscope body 1 has a tapered part 10 for inserting into an ear, the otoscope body 1 has a hollow inner cavity 11 communicated with the tapered portion 10, and an ear speculum 3 is detachably mounted on the tapered portion 10.

(7) In the embodiment, the observation apparatus 2 comprises a connecting housing 20 connected to the otoscope body 1 and an adjusting housing 21 connected to the connecting housing 20. When the connecting housing 20 is fixed with respect to the otoscope body 1, the central axis 7 of the observation apparatus 2 can only coaxial with the central axis 5 of the otoscope body 1; when the connecting housing 20 is rotatably connected to the otoscope body 1 via a rotating shaft 8 and the axis 6 of the rotating shaft 8 extends in the same direction as the central axis 5 of the otoscope body 1, rotating the connecting housing 20 may cause the central axis 7 of the entire observation apparatus 2 and the central axis 5 of the otoscope body 1 to be adjusted between being coaxial with or deviating from each other, as shown in FIGS. 1 and 2.

(8) As shown in FIG. 3, the observation apparatus 2 further comprises a first optical lenses 22 and a second optical lens 23 arranged along a same optical axis, wherein, the first optical lenses 22 are consisted of two positive lenses fixedly provided within the connection housing 20, and the second optical lens 23 is a negative lens provided within the adjusting housing 21. In the embodiment, the adjusting housing 21 is rotatably connected to the connecting housing 20, the specific structure may be a thread structure or other conventional adjusting structure, that is, the adjusting housing 21 may be considered to be a rotary knob, and the second optical lens 23 moves with respect to the first optical lens 22 along the optical axis when rotating the adjusting housing 21. This allows the focal length of the optical lens group to be adjusted to achieve the adjustment within the visual field range.

(9) In addition, an illuminating apparatus 4 is provided within the inner cavity 11. When in use, also may rotate the connecting housing 20, such that the central axis 7 of the entire observation apparatus 2 deviates from the central axis 5 of the otoscope body 1, the hollow inner cavity 11 of the otoscope body 1 exposes, and an examination component may also be extended into the ear via the inner cavity 11 for operation during observation via the observation apparatus 2.

(10) The embodiments described above are only for illustrating the technical concepts and features of the present disclosure, and are intended to make those skilled in the art being able to understand the present disclosure and thereby implement it, and should not be concluded to limit the protective scope of this disclosure.
