Description

BACKGROUND OF THE INVENTION [0002] The present invention relates to an internal structure of an endoscope,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internal structure of an endoscope, and more particularly, to an internal structure of an endoscope having a wide field of view ensuring an optical fiber installation space to secure a wide field of view through an optical fiber from a light source.

 Endoscope is a medical instrument that helps in the discovery and diagnosis of diseases and its treatment by observing the internal state of the human body and facilitating the resection of tissues and the collection of secretions.

When an endoscope is used to incise and seal the affected part of the body for the purpose of treating a disease occurring in a specific part of the thoracic cavity or the abdominal cavity or the body, a surgical instrument such as a gas injector, an electric shaver, forceps, With the endoscope inserted into the inside of the human body, the endoscope is used to observe the affected part and to perform the operation through the surgical instrument.

Such endoscopes have been developed to improve the ease of use as well as the ease of observation, and the inside of the endoscope has a very complicated structure.

In particular, the fiberoptic endoscope has a light guide for illuminating the interior of the patient's body and two glass optical fibers serving as an image guide for delivering the lesion from the distal objective lens to the eye.

On the other hand, the electronic endoscope has a kind of electronic camera at the end of the endoscope, which is a CCD, and does not need an optical fiber as an image guide, but includes only a light guide optical fiber for illuminating a light

As described above, the fiber optics, the electronic endoscope, and the like commonly use illumination as an essential element, and the installation space thereof is generally secured in proportion to the outer diameter of the endoscope.

Conventional endoscopes, however, include an aperture through which the suction and accessory mechanisms pass, an illumination lens that illuminates the optical source to secure a wide field of view through the optical fiber, an objective lens that captures and delivers the image, a tube that can spill air or water, And an angulation control wire device for supporting to move freely. Thus, it is very difficult to secure such a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to reduce the installation number of the water supply tube to increase the installation space of the optical fiber serving as a lighting, .

Other objects and advantages of the present invention will become apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

According to an aspect of the present invention, there is provided an endoscope for use in a spinal or neck disk surgery, the endoscope having a tissue collection channel in which a forceps for removing a disk, a soft tissue,

And an irrigation tube for supplying water or air to the treatment area after the tissue is recovered during or after the operation by the forceps,

The tissue collection channel is characterized in that the forceps is taken out of the body after the procedure and then the water or air supplied through the water tube is sucked and discharged to the outside.

The tissue collection channel is connected to a vacuum pump for extracting sucked water or air to the outside, and a check valve is installed between the tissue collection channel and the vacuum pump.

According to the present invention, the conventional suction tube is removed and the function of the suction tube is performed by the tissue collecting channel. Thus, the optical fiber that performs the role of the illumination as the space in which the suction tube is removed is further provided, An enlarging effect occurs.

FIG. 1A and FIG. 1B are cross-sectional views of an internal structure of an endoscope having a wide field of view according to the prior art and the present invention.
FIGS. 2A and 2B are schematic views of an endoscope applied to the conventional and the present invention. FIG.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. First, functionally identical or similar portions are given the same reference numerals throughout the drawings.

FIGS. 1A and 1B are sectional views in which an internal structure of an endoscope having a wide field of view according to the present invention is improved, and FIGS. 2A and 2B are schematic views of an endoscope applied to a conventional and an endoscope according to the present invention.

First, the internal structure of the endoscope having a wide field of view applied according to an embodiment of the present invention can grasp the installation state inside the endoscope through FIGS. 1A and 1B, and the overall installation state can be grasped through FIGS. 2A and 2B .

The present invention is not limited to the utilization of the illustrated model.

As shown in FIGS. 1 and 2, in the endoscope according to the present invention, the optical fiber for illuminating the illumination is not shown, but a special lens device is installed at both ends of the optical fiber for effectively transmitting light.

The optical fiber applied to the present invention is composed of 5,000 to 30,000 bundles each having a diameter of 30 mu m smaller than hair.

The optical fiber plays a role of illuminating the operator when the spinal or neck disk is operated, thereby securing the field of view. In the present invention, the optical fiber is provided behind the lens tube 10.

A tissue collection channel 20 for cutting or collecting a large disk or a soft tissue using a forceps or the like and for taking them out to the outside is formed in the treatment site observed through the lens tube 10 as described above.

The tissue collection channel 20 has a relatively larger diameter than the lens tube 10.

When the tissues are collected as described above, air or water should be sprayed on the treatment site or cleaned, or the foreign substance should be sucked and discharged to the outside.

In the present invention, the above-described role is taken over by the tissue collection channel 20.

The tissue collecting channel 20 is operated through the forceps or the like and then released to the outside when the procedure is completed. Subsequently, the vacuum pump is operated to form the tissue collecting channel 20 at a negative pressure state, .

On the other hand, in the above operation, the water pump is operated to discharge the water.

Water is normally delivered by the water supply button, and the circuit of the water supply system is opened, and water is sprayed to the nozzle at the tip through the water supply tube 30 by the pressure in the water supply tank.

The feed water is made small so as to make it easy to remove the foreign matter adhered to the lens, and is liable to be clogged if the washing after the use is insufficient. A check valve is attached to prevent water from backflowing. However, in case of too much water or high pressure, a small foreign body may flow backward and become blocked or infected.

The foreign substance is sucked by the external vacuum pump and the collecting bottle being connected with the passage of the tissue collecting channel 20 to form a negative pressure and sucked by pressing the suction button.

As described above, the present invention can perform a tissue biopsy and a therapeutic endoscope by inserting various attachments such as a forceps through the tissue collection channel 20, as described above.

In the present invention, as shown in FIGS. 1A and 2A, two water supply tubes 30 for performing two water supply and suction are formed as shown in FIGS. 1B and 2B, The efficiency of the space can be improved by installing the optical fiber or the like in the existing water tube 30 where the conventional tissue collecting channel 20 is installed.

The present invention may be embodied in many other forms without departing from the spirit or essential characteristics thereof. Therefore, the above-described embodiments are merely examples in all respects, and should not be construed restrictively. The scope of the present invention is indicated by the appended claims, and the present invention is not restricted by the specification. Modifications and variations falling within the scope of the appended claims all fall within the scope of the present invention.
