Multifunctional aural rigid endoscope

Abstract

The invention discloses a multifunctional aural rigid endoscope. The multifunctional aural rigid endoscope comprises an objective lens portion, an eyepiece portion, an imaging fitting joint, a lighting adjustment connecting portion, a negative pressure demisting portion and a negative pressure adherence needle. The objective lens portion, the eyepiece portion and a camera mechanism are used for photographing. During photographing, by the negative pressure demisting portion, water vapor in a human body can be sucked into a negative pressure demisting tube, and then discharged by a first rubberhose at the rear end of the negative pressure demisting tube into a collection bottle to achieve demisting, wherein the front end of a horizontal sucker of the negative pressure demisting portion is arranged beside the front end of an outer endoscope tube. During image photographing, a light adjustment piece is adjusted through a knob, the light adjustment piece and the knob are in meshed connection, and the light adjustment piece is rotated slightly while the knob is rotated. The negative pressure adherence needle is used for adhering and cleaning dirt in the ear; when the operation is completed, the medical staff put a needle body into a needle clamping slot through a clamping portion to prevent accidental injury to others.

Description

technical field [0001] The invention relates to the technical field of ear inspection equipment, in particular to a multifunctional ear rigid endoscope. Background technique [0002] At present, forehead mirrors, electric otoscopes and rigid endoscopes are widely used in clinical otology for inspection. [0003] Frontal mirrors and electric otoscopes have the following deficiencies: [0004] 1. Observation angle is limited; [0005] 2. Due to the fine structure of the ear, it is impossible to visually enlarge the lesion for diagnosis and treatment; [0006] 3. The observed situation cannot be imaged and photographed in the form of a digital image. [0007] The rigid endoscope in the prior art includes an endoscope tube, an outside mirror tube, an imaging system and an illumination system. The inner mirror tube is arranged in the outer mirror tube. The outer mirror tube connects the imaging system and the lighting system, and is the part inserted into the ear canal. Use...

AI Technical Summary

Problems solved by technology

[0004] 1. Observation angle is limited;

[0005] 2. Due to the fine structure of the ear, it is impossible to visually magnify the lesion for diagnosis and treatment;

[0006] 3. The observed situation cannot be imaged and photographed in the form of digital images

[0008] 1. Fogging: Since the rigid endoscope is made of metal, the surface temperature decreases after being soaked in enzyme solution and disinfectant solution, and the human body has body temperature. When the rigid endoscope enters the ear canal, the hot water vapor in the ear canal will liquefy when it is cooled The small water droplets condense on the surface of the lens and look like white mist under the refraction of light, which affects diagnosis and treatment. The traditional solutions are: ①Take out the endoscope, wipe it with iodophor or alcohol cotton ball, and then enter the ear again However, when re-entering, after a short period of use, a fog layer will still be formed; ②Before use, soak the endoscope in physiological saline at about 30 degrees (the soaking solution cannot be reused) for a few minutes, and make its surface temperature and When the body temperature reaches a certain level, enter the human body for observation, but it needs to be heated in time and replace the normal saline, which makes the diagnosis and treatment cumbersome; ③ using anti-fogging agent, but it is expensive and the cost is high

[0009] 2. The condition of the ear canal of different patients is different (especially postoperative patients), resulting in different refraction imaging effects of light, which directly affects the quality of imaging. If the brightness is too low, the image color is dull and unclear; if the brightness is too high, it will cause image overexposed

However, the adjustment key of the light source of the existing rigid endoscope is on the main unit, and the operator cannot adjust it at any time during the operation. cause great inconvenience
