[Name of invention]

Endoscope light source

[Technical Field]

^The present invention relates to an endoscope light source model, and more particularly, to an endoscope light source model having a structure that is installed in the endoscope to improve effective lighting.

Background Art

In general, hospitals use endoscopy for medical examinations or surgery.

(Endoscope) or laparoscope (腹腔鏡， laparoscope) are used a lot, and the optical module for the imaging of the object is necessarily applied to such a laparoscope.

Endoscopy allows you to take pictures and observe the narrow space inside the human body or inside the machine. Especially in the medical field, the endoscope uses a small camera without the need to open or cut the body such as surgery or autopsy. (Stomach, bronchi, esophagus, colon, small intestine, etc.) can be observed to check for abnormalities.

Current endoscopes are being extended not only to the medical field but also to various industrial fields such as to observe the inside of the pipe without dismantling the precision machine or to observe the abnormality of the inside of the pipe.

Conventionally known endoscope systems include lighting means for irradiating light to see the internal spectacle of the body or the inner surface of the machine, and for the light signal emitted from the lighting means to be reflected on the surface of the internal organs of the human body. A camera composed of an image pickup device for receiving an electrical signal (image signal) and a camera needle including an encoder for converting the image signal to an electronic signal for viewing on a monitor are configured at the tip of the endoscope.

The key components of the endoscope system ¾ are an imaging system and an illumination system. The imaging system may include an objective lens at the far end of the endoscope or fiber bundle and an alternative lens at the proximal end to visually observe the body.

Imaging systems of state-of-the-art endoscopic devices include, for example, camera chips and imaging optics in the form of CCD-chips or CMOS, where the reflected optical signal is converted into an electrical signal and transmitted to the near end via a wire, outside the endoscope. On the image playback unit It is visually displayed as an actual image.

Illumination means deliver light to the far end of the endoscope to indicate where to observe, and such illumination means are installed at the tip of the endoscope or are transmitted by an xenon or halogen (light transmitted through an optical pipe). External light sources such as halogen light sources, or internal light sources placed inside the endoscope, such as light emitting diodes (LEDs).

1 is a view showing an illumination means of an endoscope using an optical fiber, the illumination means 10 according to Figure 1 (a) is a reflector 12 is installed on one side of the light source 11 installed in the vertical direction and irradiated to the rear side Reflecting the light to the front side, the light collecting lens 13, 14 is installed on the other side of the light source 11 to collect and output the light directly irradiated from the light source 11 and the light reflected from the reflector 12 The light output from the light collecting lenses 13 and 14 is input to the optical fiber 15.

In addition, the lighting means 20 according to FIG. 1 (b) is provided with a reflector 22 on the rear side of the light source 21 installed in the horizontal direction so that the light irradiated from the light source 21 passes through the reflector 12. Reflected and causes the reflected light to enter the optical fiber 23.

However, the lighting means using the optical fiber has to have a separate light source to the outside, there is a problem that the light efficiency is reduced because the amount of light lost during the movement of light.

In addition, Korean Laid-open Patent No. 1038292 has proposed a laparoscope optical system having a function of preventing light loss.

The endoscope optical system is configured to prevent light loss due to transmission of illumination light incident on the beam splitter by an optical fiber having a light shielding portion in a central portion and a beam splitter having a light transmitting portion and a light reflecting portion on a slope.

However, such an endoscope optical system has a problem that a large amount of light is lost in the process of being incident to the optical fiber having a small cross-sectional area is configured so that the light output from the light source mode is directly input to the optical fiber.

In recent years, the use of LED as the light source of the endoscope has increased, but the heat of the LED is less heat than other lighting means, but when used in a closed device such as an endoscope due to the heat generated from the light emitting contact of the LED The temperature of the lighting means becomes higher than the body temperature.

In particular, when using high-brightness LEDs, efficient lighting with high light quantity is possible compared to its size, but due to the high light quantity, the temperature increases rapidly and 80 ° C Excessive fever may occur.

The heat of the LED is a problem that can cause fatal damage to the tissues and organs of the human body that is sensitive to heat and weak protein.
