Description

an otoscope

technical field

The utility model relates to an ear medical device, in particular to an otoscope used for the diagnosis and treatment of the outer ear and the middle ear. the

Background technique

When doctors do ear examinations for patients, because the ear space is relatively narrow, it is not conducive to observation, so it is necessary to use an electric otoscope to complete the examination. For example, the external auditory canal is congested, swollen, and foreign objects are present, etc., all need the electric otoscope to help complete the examination. The so-called electric otoscope mainly includes power supply, light source, observation box and magnifying glass. This kind of electric otoscope is mainly used for the examination of the outer ear and part of the middle ear. After the examination, the doctor will treat the ear according to the examination results, but Ordinary otoscopes are only convenient for observation and are not conducive to inserting surgical instruments into the ear for surgical treatment of the outer or middle ear. the

Utility model content

The technical problem to be solved by the utility model is to provide an otoscope that can insert surgical instruments to treat the ear while observing the ear, so as to overcome the above-mentioned defects in the prior art. the

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: an otoscope, which is characterized in that: it includes a mirror body, and the top of the mirror body is provided with an outwardly protruding mirror mouth, and a conical mouth is threaded on the mirror mouth. Endoscope, the tip of the endoscope is provided with an opening in the same axial direction as the endoscope, the width of the opening is a quarter of the circumference of the endoscope, and the length is half of the height of the endoscope . the

Further, there is an observation box at the upper end of the mirror body, a light bulb is arranged inside the observation box, a magnifying glass is provided at one end of the observation box close to the user, and the other end is connected with the mirror mouth, and a hand-held part is connected at the bottom of the observation box. A battery is arranged inside the part, and a switch is arranged outside the hand-held part, and the bulb and the battery are connected through a switch circuit.

As mentioned above, the otoscope of the present utility model has the following beneficial effects: since the endoscope adopts the form of a quarter side opening, when the endoscope is placed on the mirror mouth, it does not affect the ear. Observation, and ear microsurgical instruments can be inserted from the opening for external ear, part of the middle ear surgery or treatment. The device is small in size and easy to carry, and is especially suitable for performing examination and surgical treatment on patients in outpatient clinics and out for consultation. the

Detailed ways

The structures, proportions, sizes, etc. shown in the drawings of the manual are only used to match the content disclosed in the manual, and are only used to cooperate with the content disclosed in the manual, so that people familiar with this technology can understand and read, not for Limiting the limited conditions that the utility model can be implemented, so it has no technical substantive meaning, any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the efficacy and the purpose of the utility model , should still fall within the scope covered by the technical content disclosed in the utility model.

As shown in Figures 1-3, the utility model otoscope comprises a mirror body 9, and the upper end of the mirror body 9 has an observation box 5, and the inside of the observation box 5 is provided with a bulb 6, and the bulb 6 is a xenon optical fiber cold light source. The light source has no light resistance, and the bulb 6 becomes cylindrical. One end of the observation box 5 is provided with a magnifying glass 4, and the other end is connected with the mirror mouth 3. There is an optical fiber ring inside the mirror mouth 3, and the mirror mouth 3 is in the shape of a truncated cone. Look inside. A hand-held part 7 is connected to the bottom of the observation box 5, and a battery 8 is arranged inside the hand-held part 7, and the bulb 6 is connected with the battery 8. A switch 10 is arranged outside the handle 7, and the switch 10 is rod-shaped. When the switch 10 is pushed up, the current is turned on, and when the switch 10 is pushed down, the current is turned off. the

An endoscope 2 is sheathed on the mirror mouth 3 of the mirror body 9 . The endoscope 2 is in the shape of a conical cylinder, and an opening 1 along the axial direction is opened at the small mouth end of the endoscope 2 . There are protruding threads in the large mouth end of the endoscope 2, and threads corresponding to the endoscope 2 are arranged on the mirror mouth 3, and the endoscope 2 and the mirror mouth 3 are connected by threads. The size of the opening 1 is based on the ability to insert surgical instruments. Preferably, the width of the opening 1 is a quarter of the circumference of the endoscope 2 , and the length of the opening 1 is half the height of the endoscope 2 . After observing and understanding the condition in the patient's ear with the otoscope of the present invention, surgical instruments can be inserted through the opening 1 on the endoscope 2, and surgery or treatment can be performed on the inside of the ear while observing. the

In summary, the otoscope of the present utility model can solve the problem that the electric otoscope can only observe the outer ear and part of the middle ear but cannot conveniently insert surgical instruments into the ear for surgery or treatment. At the same time, the otoscope is small in size and easy to carry. It is especially suitable for examination and surgical treatment of patients in outpatient clinics and outpatient consultations.
