Description

Miniature endoscope structure

This creation is related to an endoscope structure, especially a miniature endoscope structure.

According to the conventional endoscope illumination technology, for example, the new patent of Taiwan Patent No. M421091 is provided with a plurality of LEDs at the front end of the endoscope to provide a light source for guiding light. However, due to the large volume of the LED, The size of the endoscope is relatively large, and often exceeds 3 mm in diameter. Therefore, it is easy to cause discomfort to the user during use, and cannot be applied to a place with a small hole.

In view of this, the manufacturer removes the LED, so that the diameter of the endoscope is reduced to 2 mm or less, and becomes a miniature endoscope. However, since the brightness of the micro endoscope is insufficient, external fiber-optic illumination must be inserted into the user cavity. In the body, the user's discomfort is also caused during use, and the operation is limited due to the inability of the optical fiber itself to perform a large bending operation.

In addition, in general, the protective lens for the front end of the endoscope must be adhered to the peripheral side to prevent water seepage, so as to form a waterproof effect, but the sealing glue not only makes the production process complicated, but also has water seepage.

Therefore, after the creators of this case observed the above shortcomings, they believed that the existing miniature endoscopes had the need for further improvement, and there was no such creation.

The main purpose of this creation is to provide a miniature endoscope structure that provides excellent illumination in a miniaturized size.

The secondary objective of this creation is to provide a miniature endoscope structure with simplified components and excellent water resistance.

For the above main purpose, the micro endoscope structure provided by the present invention comprises a cable; and an image capturing device is disposed on the front end of the cable, and the image capturing device has an inductor. The rear end of the sensor is electrically connected to the cable, and the image capturing device is provided with a lens at the front end of the sensor, and the image capturing device is provided with a plurality of self-illuminating members on the sensor; and a cover. The main body is closed at one end, so that the outer cover forms an opening along one end of the axis, and the other end is integrally formed with a front stop portion, wherein the opening portion is fixed on the cable, so that the image capturing device is located In the outer cover, the front stop portion is located just before the lens to protect the lens.

In order to achieve the above secondary purpose, the micro endoscope structure provided by the present invention is made of a transparent optical material, and the front end portion is located in front of the lens to protect the lens.

The micro endoscope structure of the present invention has the characteristics of small size and high brightness through the self-illuminating members, thereby increasing the overall illumination brightness, and using the image capturing device to obtain a clearer image during shooting, and the cover Made of transparent optical material, it is a tube body closed at one end, and the front stop is located in front of the lens, so there is no gap, high sealing degree and good waterproof performance, which can avoid liquid infiltration. A short circuit is caused by the device.

The front surface 222 of the sensor 22 is formed with four end portions 223 formed on the outer peripheral side of the lens 23, and the image capturing device 20 is provided with a plurality of self-illuminating lights on the sensor 22 In the embodiment, the self-luminous light-emitting members 25 are respectively disposed on the side surface 221 of the inductor 22, wherein the self-luminous light-emitting members 25 are organic light-emitting diodes (OLEDs). The surface is curved and convex.

An outer cover 30, which is made of a transparent optical material, has a tubular body closed at one end, and the outer cover 30 has an opening 31 formed at one end of the axis, and a front stop portion 32 is integrally formed at the other end. The opening portion 31 is fixed on the cable 10 such that the image capturing device 20 is located in the outer cover 30, and the front stop portion 32 is a straight segment, and the front stop portion 32 is perpendicular to the The axis of the outer cover 30 is located just before the lens 23 to protect the lens 23. In this embodiment, the inner wall 301 of the outer cover 30 is respectively provided with an arc corresponding to the self-illuminating member 25 Groove 302.

In order to further understand the characteristics of this creation, the use of technical means and the expected results, we will describe the use of this creation, and believe that we can have a deeper and more specific understanding of this creation, as follows:

When the present invention is used, the self-illuminating member 25 is used to provide a light source. Since the self-illuminating members 25 are OLEDs, the OLED has the characteristics of a pixel, that is, a light source, and thus has a smaller size than a conventional LED. The high-intensity and low-power consumption, after the self-illuminating members 25 are illuminated, the curved recesses 302 of the outer cover 30 can be used to reflect and collect the light of the self-illuminating members 25 to increase the overall brightness. For the inspection of organs or surgery, it can assist in illuminating the internal position of the cavity of the human body, so that the image capturing device 20 can obtain more sufficient brightness when shooting, and can obtain a clearer image.

Next, referring to FIG. 5, FIG. 6, and FIG. 7, an exploded view, a cross-sectional view, and a front view of a second embodiment of the present invention, the second embodiment of the present invention is different from the first embodiment. The self-illuminating members 25 are respectively disposed on the end portions 223 of the inductors 22.

Next, referring to FIG. 8, a cross-sectional view of a third embodiment of the present invention is different from the foregoing first embodiment in that the front cover portion 32 of the outer cover 30 is non-straight. One of the irregular curved surfaces or the spherical surface, the front stop portion 32 has a focusing characteristic, so that the front stop portion 32 can replace the lens 23 for imaging.

It should be noted that the self-illuminating material 25 can also be a self-luminous coating, and the self-luminous coating can be selected from one of a fluorescent coating or a phosphorescent coating, and the self-illuminating member 25 is disposed on the image by coating. The periphery of the device 20.

Hereby, the characteristics of this creation and its achievable expected effects are stated as follows:

1. The self-illuminating member 25 of the present invention has the advantages of small volume, high brightness and low power consumption, so that the creation can be reduced to a diameter of less than 2 mm to meet the requirements of miniaturized endoscopes.

2. The outer cover 30 of the present invention is made of a transparent optical material, which is substantially closed at one end, and the front stop portion 32 is located in front of the lens 23, so that no gap can be achieved, and the degree of sealing can be achieved.
