Description

Medical examination otoscope

Technical Field

The utility model relates to the field of medical equipment, specifically a medical examination otoscope.

Background

Otoscopes are used primarily to view the ear canal and tympanic membrane during otological procedures. The prior otoscope is in a round table cylinder shape, and the aperture is fixed and can not be changed. During treatment, the small hole part is inserted into the ear hole, and the large hole part is used for observation. Because the shape and the size of the auditory canal of a patient are different, the aperture of the otoscope cannot be changed by using the same otoscope for examination, which causes the defects of unclear visual field, hard observation, long treatment process, low efficiency and the like sometimes.

SUMMERY OF THE UTILITY MODEL

For solving the problem in the prior art, the utility model provides a following technical scheme:

the utility model provides a medical inspection otoscope, includes the lens cone, expands ear clamp and operating handle, be equipped with optical imaging module in the lens cone, the lens cone front end is equipped with conical lens, expand the ear clamp and adopt two split type symmetrical structure and all be fixed in the operating handle upper end, expand the ear clamp inner wall and reach the conical lens periphery all is equipped with the screw thread, the lens cone the conical lens part with expand the ear clamp and connect soon, the conical lens end is equipped with wide angle fisheye lens, the conical lens inner wall is equipped with annular optical fiber, under initial condition conical lens is terminal wide angle fisheye lens part hide in expand inside the ear clamp.

Furthermore, the periphery of the lens barrel is provided with a fixing ring, the lens barrel is screwed with the fixing ring through threads, and the fixing ring is fixedly connected to the upper end of the operating handle through support legs.

Further, the annular optical fiber and the wide-angle fisheye lens are wrapped peripherally.

Furthermore, an LED light source is arranged inside the operating handle and connected with the annular optical fiber.

Furthermore, an adjusting knob is fixedly arranged on the periphery of the rear end of the lens barrel.

Furthermore, the ear expanding clip is made of a titanium alloy elastic metal material.

The beneficial effects of the utility model reside in that: the lens cone front end is equipped with conical lens, expand the ear clamp inner wall and conical lens periphery all is equipped with the screw thread, the lens cone conical lens part with expand the ear clamp and connect soon, expand the ear clamp and adopt two split type symmetrical structure and all be fixed in the operating handle upper end, under the effect of screw thread, when conical lens outwards back-out, make expand the terminal mouth grow of opening of ear clamp, expand patient's duct to can prevent the influence of duct hair wide angle fisheye camera lens is to the formation of image at focus position, simultaneously wide angle fisheye camera lens periphery parcel has annular optical fiber, does wide angle fisheye camera lens formation of image provides the light source.

description of reference numerals: the lens barrel comprises a lens barrel 1, an ear expanding clamp 2, an operating handle 3, a conical lens 4, a wide-angle fisheye lens 41, an annular optical fiber 5, a fixing ring 6, a support leg 7, an LED light source 8 and an adjusting knob 9.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 1, fig. 2 and fig. 3, a medical examination otoscope comprises a lens barrel 1, an ear expanding clamp 2 and an operating handle 3, wherein an optical imaging module (not shown in the figure) is arranged in the lens barrel 1, the front end of the lens barrel 1 is provided with a cone-shaped lens 4, the ear expanding clamp 2 adopts a two-segment split type symmetrical structure and is fixed at the upper end of the operating handle 3, the inner wall of the ear expanding clamp 2 and the periphery of the cone-shaped lens 4 are both provided with threads, the cone-shaped lens 4 part of the lens barrel 1 is screwed with the ear expanding clamp 2, the tail end of the cone-shaped lens 4 is provided with a wide-angle fisheye lens 41, the inner wall of the cone-shaped lens 4 is provided with an annular optical fiber 5, the wide-angle fisheye lens 41 part at the tail end of the cone-shaped lens 4 is hidden in the ear expanding clamp 2 in the initial state, and along with the screw, the auditory meatus and the hair in the auditory meatus are spread, and meanwhile, the wide-angle fisheye lens 41 at the tail end of the conical lens 4 and the annular optical fiber 5 are slowly pushed out, so that the wide-angle fisheye lens 41 can fully observe the focus part; the periphery of the lens barrel 1 is provided with a fixing ring 6, the lens barrel 1 is screwed with the fixing ring 6 through threads, and the fixing ring 6 is fixedly connected to the upper end of the operating handle 3 through a support leg 7, so that the lens barrel 1 can stably drive the conical lens 4 to move on the ear expanding clip 2; the annular optical fiber 5 and the wide-angle fisheye lens 41 are wrapped peripherally; an LED light source 8 is further arranged inside the operating handle 3, the LED light source 8 is connected with the annular optical fiber 5, a light source is provided for the imaging of the wide-angle fisheye lens 41, and the imaging of the wide-angle fisheye lens 41 is influenced; an adjusting knob 9 is fixedly arranged on the periphery of the rear end of the lens barrel 1, so that the lens barrel 1 can be conveniently rotated; the ear expanding clip 2 is made of titanium alloy elastic metal materials, and after the ear expanding clip is used, when the conical lens 4 returns to the initial position, the ear expanding clip 2 can return to the initial state.

When in specific use, through adjust knob 9 will conical lens 4 adjusts to the initial value position, will expand in the ear clip 2 stretches into the duct, then adjust knob 9, and switch on led light source 8 power, until the focus position is observed clearly.

It should be noted that, in this document, the ring-shaped optical fiber 5, the led light source 8, the optical imaging module and the wide-angle fisheye lens 41 are all prior art in the field of this application, and above, only the embodiment of the present invention is not limited to the embodiment of the present invention, and the patent scope of the present invention is all utilized by the equivalent structure or equivalent flow conversion made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
