Abstract

The utility model relates to an oral endoscope that uses LED as the auxiliary light source. The utility model provides the LED at the edge of the lower surface of the lens of the traditional oral endoscope, a button battery is used to supply the power for the LED, the lens surface of placing the LED is not plated with silver, thus making the LED light can be permeated out, therefore, the utility model can carry out the oral check-up without the use of external auxiliary light source.

Description

A kind of LED is as the stomatology endoscope of secondary light source

Technical field

This utility model be a kind of with LED be luminous optical diode as backlight, do not need to use secondary light source, be used for the stomatology endoscope of examination of mouth.

Technical background

At present the stomatology endoscope that is used for examination of mouth that uses of hospital has only the common eyeglass of a slice, do examination of mouth and must carry out floor light by indoor natural light or secondary light source (pocket lamp etc.) in addition, and so operation was both inconvenient and be difficult for seeing clearly the depths, oral cavity.Improving endoscope structure, not only made things convenient for effect but also good when it is used, is oral cavity doctor's desired destination.

Summary of the invention

The purpose of this utility model is to obtain a kind of simple in structure, stomatology endoscope that has led light source that result of use is good, makes examination of mouth not need outside secondary light source.

Stomatology endoscope of the present utility model is to be made of endoscope's eyeglass, led light source, button cell, endoscope handle several sections, LED (2) is placed at eyeglass (1) lower edge place at stomatology endoscope, button cell (3) is positioned at endoscope handle (4), it connects LED (2) by lead, endoscope lens edge place on LED does not have silver-plated, makes LED luminous energy appear, and endoscope handle (4) is a plug-in, there is switch (5) the handle outside, and whether its control LED lights.

In this utility model, LED (2) has 1-4.

In this utility model, LED (2) is a paster LED.

Adopt paster LED, because relatively power saving of LED can be powered with button cell, battery is placed on the endoscope handle the inside.

This utility model has following characteristics:

1 LED is used in the stomatology endoscope as secondary light source;

2 usefulness button cells are powered to LED, whether are lighted by an on-off control LED;

The local lens surface of 3 placement LED is not silver-plated, can make LED light appear.

4 endoscope handle are detachable, and are reusable.

This utility model adds that LED carries out floor light around traditional stomatology endoscope eyeglass, make examination of mouth not need special secondary light source, and is convenient many.Because the LED volume is little, brightness is high, power consumption is little, therefore can directly power to LED with button cell, on the basis that does not change existing dental mirror structure substantially, promoted result of use greatly.

Description of drawings

Fig. 1 is with the stomatology endoscope structural representation of LED as secondary light source.

1 is endoscope's eyeglass among the figure, the 2nd, and LED, the 3rd, button cell, the 4th, endoscope handle, the 5th, switch, the 6th, metal electrode.

The specific embodiment

The used element of this utility model is as follows:

LED: paster LED, three;

Power supply: button cell;

Endoscope's eyeglass: common reflex reflector lens;

Endoscope handle: the handle that adopts plastics.

The instrument assembling process:

Assemble according to figure (1), LED is placed on endoscope's eyeglass bottom on every side, and is not silver-plated above the eyeglass of placement LED, and button cell is placed on the endoscope handle the inside, button cell output receive on the LED by lead, lead is embedded in the eyeglass bottom, and endoscope handle is not made plug-in, and is in the time of no detachable, handle is reusable, one switch is installed on the handle, can be controlled whether lighting of LED, can reach the effect of power saving.

Claims

1, a kind of LED is as the stomatology endoscope of secondary light source, constitute by endoscope's eyeglass, led light source, button cell, endoscope handle, it is characterized in that eyeglass (1) lower edge place placement LED (2) at stomatology endoscope, button cell (3) is positioned at endoscope handle (4), it connects LED (2) by lead, endoscope lens edge place on LED does not have silver-plated, make LED luminous energy appear, endoscope handle (4) is a plug-in, there is switch (5) the handle outside, and whether its control LED lights.

2, stomatology endoscope according to claim 1 is characterized in that LED (2) has 1-4.

3, stomatology endoscope according to claim 1 is characterized in that LED (2) is a paster LED.
