Embodiment 1

[0029] Such as figure 2 , image 3 As shown, a specific embodiment of the present invention mainly includes an optical system housing 1 and a mirror body 11 used as a main body, a lens assembly 2 arranged on the optical system housing 1, and a light-sensitive sensor arranged inside the optical system housing 1. Component 3, lighting component 6.

[0030] The optical system housing 1 is casted from conventional materials such as engineering plastics or aluminum, and the lens assembly 2 is a well-known technology in the technical field, which will not be repeated here.

[0031] The photosensitive component 3 is a CMOS (Complementary Metal Oxide Semiconductor: Complementary Metal Oxide Semiconductor) component, and is arranged on the same optical axis as the lens component 2 . In other embodiments, the photosensitive component 3 may also use a CCD (Charge Coupled Device: Charge Coupled Device) component.

[0032] The lighting assembly 6 includes an LED assembly 61 used as a l...

Embodiment 2

[0054] Such as Figure 6 As shown, a specific embodiment of the electronic otoscope using the focusable electronic optical system of the present invention includes at least an otoscope body, and the focusable electronic optical system of the present invention is arranged in the otoscope body.

[0055] Specifically, the otoscope body mainly includes an abutting shell 10 and a connecting piece for fixing, and the focus-adjustable electron optical system is fixedly arranged inside the shell 10 through the shell 1 . The shell 10 can be realized by conventional technical means such as one-shot molded parts. The way of fixed connection of the adjustable focus electron optical system in the housing 10 is also a known technology, which will not be repeated here.

[0056] The specific structure and beneficial effects of the electronic otoscope of the present invention will be described in detail below in combination with the method of using the electronic otoscope of the present inven...

Abstract

The invention discloses an electro-optical system with adjustable focus. The electro-optical system at least comprises a body, a lens assembly arranged on the body, a light sensing assembly arranged with optical axis the same as that of the lens assembly, and a manual focusing structure, wherein the light sensing assembly and the manual focusing structure are arranged in a linked manner to adjust the focus between the light sensing assembly and the lens assembly. The invention also discloses an electronic otoscope applying the electro-optical system with adjustable focus. According to the invention, as the manual focusing structure is arranged, the focus can be adjusted manually in time according to the actual visual effect of the user in focusing operation, particularly, fine focus delayed in response of the existing electronic focusing structure can be adjusted, thereby having the beneficial effects of being high in focusing precision, convenient in focusing operation and the like.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an adjustable focus electron optical system. The invention also relates to an electronic otoscope using the electronic optical system. Background technique [0002] Clinically, when medical personnel observe or treat the ear canal and eardrum of a patient, they need to use special medical instruments, such as electronic otoscopes. [0003] Such as figure 1 As shown, the applicant has previously applied for a Chinese utility model "portable electronic otoscope", and the disclosed technical solution mainly includes: a handle, an observation unit is arranged on the upper front side of the handle, and the observation unit is accommodated in a strip-shaped sleeve In the tube 51 , the front end of the sleeve 51 is an observation end, and the rear end of the sleeve 51 is used to connect with the handle. Wherein, the observation unit at least includes: an optical imaging sy...
