Abstract

The utility model relates to a medical appliance. A light source of the medical appliance is directly guided into the medical appliance so that light is avoided being shaded. The utility model discloses a medical light guide opener. The utility model comprises an upper beak and a lower beak, and an opening is formed at the back ends of the upper beak and the lower beak. A support shaft used as a support point is arranged on the upper beak so that the on-off operation can be carried out up and down between the upper beak and the lower beak, and a screw rod which penetrates through a slot hole is protruded and extended on a grip of the lower beak. Adjusting nuts which can adjust the on-off degree between the upper beak and the lower beak are arranged. The utility model is characterized in that a light guide part is extended at the back end of the inner edge of the upper beak arranged above the opening so that the light guide part is integrated with the upper beak; a light leading joint which can be connected with an optical fiber tube is convexly arranged at the back end of the light guide part, and an inclined plane which can enable an irradiation angle of light to be wide and average is formed at the front end of the light guide part. The utility model is used for examining women's uteri.

Description

Medical leaded light dilator

This utility model relates to medical apparatus and instruments.

Existing gynecologial examination dilator is commonly called as duckbilled.This apparatus is a kind of to be configuration one portable projection light fixture on interior diagnostic table, another kind is to wear a head lamp at doctor's head, but when checking, operator's hand regular meeting shelters from light source, can only observe the part at most, and do not see clearly, and therefore can cause the prolongation consultation hours, bring misery to the patient; In addition, this dilator is repeated use, so the safety and sanitation problem also causes anxiety in fact.

The purpose of this utility model provides a kind of medical leaded light dilator that can avoid blocking light source.

The purpose of this utility model is achieved in that medical leaded light dilator, it comprises beak, following beak, and the two rear end is formed with an opening, should go up beak and be provided with the fulcrum that can be made as fulcrum with the mutual folding up and down of following beak, protruded out a screw rod on one handle of infra beak, and be extended through slotted eye and establish an adjustment nut of adjusting upper and lower beak opening degree; It is characterized in that: be positioned at the last beak inner edge rear end of above-mentioned opening top position, one is extended with a light guide section, and this light guide section is solid shape, and the rear end is convexly equipped with a light lead joint that can connect optical fiber tube, and front end forms the wide and average inclined-plane of irradiating angle that can make light.

Above-mentioned design, owing on last beak body, directly be provided with light guide section, thus reached the effect of avoiding blocking light source.

Below by drawings and Examples this utility model is described further again:

Fig. 1 is this utility model stereoscopic figure;

Fig. 2 is this utility model user mode and partial sectional view;

Fig. 3 implements sketch map for this utility model cooperates light source;

As Figure 1-3: this utility model comprises beak 11, following beak 12, and the two rear end is formed with an opening 14, should go up beak 11 and be provided with the fulcrum 121 that can be made as fulcrum with following beak 12 mutual foldings up and down, protruded out a screw rod 123 on one handle 122 of infra beak 12, and be extended through slotted eye 1121 and establish an adjustment nut 124 of adjusting upper and

lower beak

11,12 opening degrees; It is characterized in that: the last beak 11 inner edge rear ends that are positioned at above-mentioned opening 14 top positions, one is extended with a light guide section 13, this light guide section 13 is solid shape, and the rear end is convexly equipped with a light lead joint 132 that can connect optical fiber tube, and front end forms the wide and average inclined-plane 131 of irradiating angle that can make light.Wherein, last beak 11 is made for being applicable to deserted transparent material.

As shown in Figure 4, upper and

lower beak

11,12 junctions of its dilator 1 are made as pivot hole 111 and establish fulcrum 121 and movable handle 112.Light lead joint 132 can be from connecing optical fiber tube 2 and connecting a luminous machine 3.

The utility model has following advantages:

1, mat light guide section guiding can directly be illuminated clearly light-source brightness to women's lower part of the body inside.

2, this light guide section is solid and takes the form of inclined plane in front end, can make the light source irradiation space wide and average.

3, since dilator for to make with transparent material, directly in the diagnosis and treatment internal illumination, be not subjected to so do not have Extraneous factor affects and the problem of generation shading.

4, leaded light mode of the present utility model utilizes thin glass fiber to carry out optic communication with an optical fiber tube, has safe and simple characteristic in the use.

5, dilator simple structure, cost is with low cost, is applicable to desertedly, can meet health demand.

Claims

1, medical leaded light dilator, it comprises beak, following beak, and the two rear end is formed with an opening, should go up beak and be provided with the fulcrum that can be made as fulcrum with the mutual folding up and down of following beak, protruded out a screw rod on one handle of infra beak, and be extended through slotted eye and establish an adjustment nut of adjusting upper and lower beak opening degree; It is characterized in that: be positioned at the last beak inner edge rear end of above-mentioned opening top position, one is extended with a light guide section, and this light guide section is solid shape, and the rear end is convexly equipped with a light lead joint that can connect optical fiber tube, and front end forms the wide and average inclined-plane of irradiating angle that can make light.

2, medical leaded light dilator as claimed in claim 1 is characterized in that: wherein, last beak is to be applicable to that deserted transparent material makes.
