Description

The present invention relates to a capsule endoscope having a front end,

[0001] The present invention relates to a capsule endoscope for use in frontal tattoos, and more particularly, to a capsule endoscope for front tattooing and a capsule endoscope for front tattooing, in which needle withdrawal toward the lesion is made toward the front of the lens, .

As a method for determining whether or not a digestive organs of a human body has disease or pathology, there is a single-layer (CT) imaging test method for examining a tomographic image of a human body obtained using ultrasonic waves or images obtained by using an ultrasonic wave. These inspection methods have limitations in that they can not go beyond the range of diagnosis based on images obtained indirectly.

Accordingly, an endoscopic examination method in which a diagnosis expert diagnoses the inside of the subject's digestive organs by directly looking at it is preferred because it enables the most reliable diagnosis.

As a means for such an endoscopic examination, a wire endoscopic apparatus is used, but it causes inconvenience of a patient in the process of inserting the endoscope into the oral cavity or anus of the patient, and side effects due to drugs provided to alleviate such inconvenience occur There was a problem.

In order to solve such a problem, a capsular type endoscope (hereinafter, referred to as a 'capsoscopic endoscope') capable of being swallowed through the oral cavity has been developed.

As long as the patient swallows the capsule endoscope, the image data of the internal digestive organs captured by the camera of the endoscope can be transmitted to an external receiver and reproduced in a monitor.

Such a capsule endoscope may be provided with a built-in magnetic body, as disclosed in Korean Patent Registration No. 10-1620624, in order to enable movement of the capsule endoscope through the control of a diagnostic person in the digestive organs.

On the other hand, the capsule endoscope not only captures image data of the digestive organs, but also serves as a function of collecting the biomedical tissue in the digestive organ as disclosed in the above-mentioned prior art.

In addition, there has been known a technique for enhancing convenience in performing minimally invasive surgery, such as laparoscopic surgery, by placing a stylus needle on the capsule endoscope and performing tattooing of the intestinal lesion by tattooing.

In other words, to perform minimally invasive surgery such as laparoscopic surgery, the intestinal lesions detected during the imaging procedure are displayed, and the operation is performed to find the marked area. In the past, a streamlined endoscope and a separate index needle However, in recent years, the endoscopic capsule has been equipped with an integrated needle for visualization, and it is possible to simultaneously perform tattooing of the intestinal lesion, thereby enhancing the convenience of imaging and tattooing using the capsule endoscope One technique is known.

This is already disclosed in a paper entitled " A compact targeted drug delivery mechanism for a next generation wireless capsule endoscope " (June 2016, Journal of Micro-Bio Robotics).

However, the above-mentioned conventional prior art also has the following problems.

First, there is a problem that tattooing is not suitable because the technical configuration for drawing out the needles and the technical structure for injecting the tattoo solution are separately formed.

Particularly, since the pull-out direction of the needles is configured not to be parallel to the front face (lens direction) of the capsule endoscope but perpendicular to the capsule endoscope, it is difficult to perform tattooing accurately on lesions.

Such a prior art documented endoscopy is a technique designed for drug delivery in digestive systems rather than tattooing.

Second, there is a problem in that the technical structure for drawing the needles and injecting the tattoo solution is complicated.

Therefore, there is a problem that the probability of malfunction is high and it is difficult to increase the satisfaction of a diagnostician for performing tattooing, and the manufacturing cost is increased.

In particular, because of the complicated internal structure of capsules, it is difficult for a diagnostician to construct a magnetic body for controlling the capsule endoscope arbitrarily in the capsule, and the prior art has a limitation in that the capsule endoscope must be moved only by the digestive organs digestive organs.

5C, the needle 300 fixed to the first original plate 511 is also moved toward the rear cover 220 as the first original plate 511 is pushed out, while the second original plate 521 pushes the first original plate 511, The lesion is removed.

After the tattooing is completed, the capsule endoscope is discharged to the outside of the body through the digestive organs, thereby completing the imaging and tattooing through the capsule endoscope.

As described above, according to the present invention, there is a technical feature that the capsule endoscope for both front and back tattooing can move the needle toward and away from the lesion using the elastic force of the spring provided on both sides of the needle.

Accordingly, the needle for tattooing is drawn to the front of the lens of the endoscope, so that high-quality tattooing can be performed by securing the forward view of the endoscope. By simplifying the configuration, malfunctions can be reduced and the endoscope can be miniaturized, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
