Description

Guider for an endoscopic device and an endoscopic device including the same {GUIDER FOR AN ENDOSCOPIC APPARATUS AND AN ENDOSCOPIC APPARATUS INCLUDING THE SAME}

The present invention relates to a guider for an endoscopic device and an endoscopic device including the same. In particular, a guider for an endoscopic device that guides a soft forcep to be easily inserted into a biopsy channel of the endoscopic device. and an endoscopic device including the same.

Since the endoscope was first created by Kussmaul in Germany in 1868, it has reached the current endoscope thanks to the development of optical technology, the development of optical fibers, and the rapid development of electronic engineering, and has greatly contributed to the development of modern medicine.

The end of this endoscope is inserted into an organ inside the human body, radiates light (visible light) to the inner wall of the organ, and then converts the reflected object into an electrical signal using an imaging device and displays it on a monitor. Unlike X-ray images, CT (Computed Tomography) images, and ultrasound images, the endoscopic images obtained in this way have the advantage of being able to capture color images, have no radiation exposure, and enable real-time imaging.

There are dozens of types of endoscopes used in each clinical department of a large hospital. The principles are generally similar, but the names are different depending on the part used, the required appearance (thickness and length, etc.) is different, and the flexibility is different. Accordingly, endoscopes can be broadly classified into rigid endoscopes (rigid endoscopes) and flexible endoscopes (flexible endoscopes).

A rigid endoscope has a longitudinal endoscope tube made of metal and the inside is filled with a rod lens. Rigid endoscopes include an otoscope, sinuscope, laryngoscope, and laparoscope. There are Laparoscope, Cystoscope, and Arthroscope.

Flexible endoscopes are represented by gastrointestinal endoscopes, and include gastroscopes and colonoscopes. Since the flexible scope must reach the affected area along a curved path such as the stomach or colon, it must have a flexible body that can manipulate the joints.

Until the 1980s, endoscopes using optical fiber image guides were mainly used, but due to limitations in resolution, from the 1980s onwards, imaging devices (Charge Coupled Devices, CCDs) using semiconductor technology began to replace optical fiber bundles for image transmission, and are currently used. Nowadays, electronic endoscopes using CCD (or CMOS) are being used in almost all flexible endoscopes. Among flexible endoscopes, an optical fiber bundle is used as an image guidance device only when the outer diameter must be absolutely thin even if the number of pixels is low. Since most fire extinguisher endoscopes are manufactured as electronic endoscopes using an imaging device, the term electronic endoscope is used to mean flexible endoscope. The terms are being used interchangeably. Against this background, flexible endoscopes, electronic endoscopes, gastrointestinal endoscopes, and gastric (colon) endoscopes are used with similar meanings.

Since the flexible endoscope follows a curve that runs from the mouth to the esophagus to the stomach, a configuration for this is necessary. In other words, the flexible endoscope is generally inserted into the organs of the human body and has an insertion part including a distal tip and a bending part, a handle for adjusting the distal end of the insertion part in four directions up, down, left, and right, and a It consists of a control unit including a valve for injecting or suctioning air and liquid into the organ, and a connection unit connected to an image processing device.

In addition, on the front of the tip, there is a light for irradiating light into a dark space, a camera module for imaging (including an objective lens and an imaging device), a nozzle for spraying air or liquid to secure an imaging space, and a biopsy device. A biopsy channel or instrument channel is formed through which instruments such as forceps for treatment and treatment enter and exit. Here, biopsy refers to collecting a tissue sample from a suspicious area using forceps or removing a polyp that has formed within the body during an endoscopic examination.

When the above-mentioned biopsy is necessary during endoscopy, the biopsy was previously performed by manually inserting the end of a soft forceps into the introduction of the biopsy channel formed in the control unit and then withdrawing the forceps through the end of the distal end. However, this method has the disadvantage that it is cumbersome to insert the forceps into the biopsy channel because the forceps are held by hand and then inserted into the biopsy channel introduction, and it is difficult to control the degree of insertion of the forceps.

Meanwhile, the technology behind the present invention is disclosed in Korean Patent Publication No. 10-2019-0094075.

The present invention was created to solve the above-mentioned problems, and includes a guider for an endoscopic device that guides a soft forceps to be easily introduced into the biopsy channel of the endoscopic device, and an endoscope including the same. Provides a device.
