Abstract

The present invention relates to an endoscopic joint structure which can be bent in a desired direction by using magnetic force of electromagnets and thus does not need an additional bending device or operational force. More particularly, node units, including electromagnets formed on upper sides, lower sides, left sides, and right sides, are joined to each other while being placed apart from each other; currents in different polarity directions are provided to one row of the electromagnets facing each other; and the electromagnets are attracted to each other to come in close contact with each other as attractive force is generated on each electromagnet. Current in the same polarity direction is provided to the other row of the electromagnets to generate repulsive force on each electromagnet, and consequently the node units are bent. When power supply to the electromagnets is cut, the node units restore original positions by elasticity. Therefore, the node units can be bent in any direction without limitation by using repulsive force and attractive force of the electromagnets.

Description

Endoscopic joint structure < RTI ID = 0.0 >

The present invention relates to an endoscope joint structure, and more particularly, to an endoscope joint structure that can flex in a desired direction by using a magnetic force of an electromagnet and does not require a device for bending or an operating force separately.

In general, endoscopic surgery is performed by inserting a camera-equipped endoscope and a surgical tool through a small hole without performing a large incision on the human body, thereby performing surgery while examining the patient's lesion through the endoscopic image.

Especially, endoscopic surgery, which started from laparoscopic surgery, is advantageous in that it has less scarring and less bleeding compared to open surgery, so that the recovery time of surgical patients is faster.

Thus, in recent years, not only has technology developed to enable endoscopic surgery for almost all operations requiring open surgery, but endoscopic surgery is also being applied to other medical fields.

However, in the conventional endoscope constructed as described above, most of the inside of the human body is illuminated through a separately provided light source, and the affected part is observed using a costly optical system such as an optical fiber bundle or a rod lens, There was no problem. Since the light source that illuminates the light through the endoscope is expensive, a large amount of electric power is continuously supplied, the power loss is large, and the camera system for photographing the affected part is expensive. .

In addition, all conventional endoscopes have a rigid shape that is bent in an entirely curved shape or not at all, and in the case of a curved shape, it is difficult to secure a fixed field of view in a region where observation is desired in the cases of oral cavity, nasal cavity, There is a disadvantage that it is somewhat uncomfortable to use and it takes a lot of time for consultation.

On the other hand, in the case of the rigid type, there is a case in which access to the deeper lesion is difficult, and in the case where the patient is moved rapidly, there is a problem in safety that the rectal canal can impact the pharynx and cause injury.

In order to solve such a conventional problem, the registration No. 10-0704724 discloses an imaging apparatus having a photographing section for observing the larynx, a bending section connected to the photographing section for operating the photographing section upward and downward, And a knob for receiving and supporting the end portion of the rigid portion are integrally formed and can be rotated up and down to observe the nasopharynx during upward flexion as well as the larynx and hypopharynx in the downward flexion, A bending type electronic laryngoscope capable of diagnosing an oral cavity and an oropharynx by observing the anterior mouth during insertion into the oral cavity, A ring-shaped operation member which is stacked at least on one side in a downwardly rotatable manner; A pair of spring or elastic members for supporting the body of the stacked operation member through the both sides so as to be rotatable from one side to the other side; A pair of connection members which are opposed to each other such that the operation member is rotated in the same direction; A rotating member for rotating the pair of connecting members in a vertical direction is mounted on the handle, the operating member includes a receiving hole for receiving a pair of connecting members each penetrating the upper and lower portions of the ring- ; And a fitting hole penetrating the right and left sides of the body so as to respectively receive a pair of spring or elastic members in the form of a bar.

However, the conventional bending type electromagnetic laryngeal endoscope has a problem in that it requires a separate reinforcement device for enduring the tensile force when pushed and pulled by using the pair of connecting members.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide an endoscope joint structure capable of freely bending a bending direction using a repulsive force and a pulling force by a magnetic force of an electromagnet.

It is another object of the present invention to provide an apparatus for bending a magnetic force generated by an electromagnet so as to prevent an action force by a force.

In addition, another object of the present invention is to make the structure simple and easy to operate.

In order to achieve the above object, according to the present invention, there is provided a refraction node structure of an endoscope, wherein the nodes having electromagnets formed on the upper and lower sides, left and right sides are connected to each other so as to be spaced apart from each other, A force is generated in the respective electromagnets to be brought into close contact with each other, and the polarity direction of the current is similarly applied to the other columns of the electromagnets, so that a repulsive force is generated in each electromagnet, The endoscope is restored to its initial position by the endoscope.

INDUSTRIAL APPLICABILITY As described above, the present invention has the effect of flexing the bending direction freely using the repulsive force and the attractive force by the magnetic force of the electromagnet.

Further, by operating with magnetism by the electromagnet, there is an effect that an additional device for bending and an action force by attraction are not required.

In addition, since the structure is simple and the operation is simple, there is an effect that it can be operated by only one hand.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

1 to 3, the endoscope joint structure of the present invention relates to a bending node structure of an endoscope, in which first to fourth electromagnets 11 to 14, which receive currents respectively, The endoscope joint 100 is formed of the nodule 10 formed in the first to n-th segments 20a to 20n.

In the endoscope 100, the nodules 10 on which the electromagnets are formed are spaced apart from each other.

At this time, the nod 10 connects the first to fourth electromagnets 11 to 14 with the insulating member 15 to form first nod 20a to nth nod And a node 20n.

On the outer surfaces of the first to fourth cores 21 to 24 of the first to fourth electromagnets 11 to 14 respectively formed in the first to nth poles 20a to 20n, The first to fourth wires 25 to 28 are respectively wound so as to be orthogonal to the longitudinal direction so that the currents can be supplied independently.

That is, the first to fourth nodal segments 20a to 20n are formed in the shape of a circular ring by connecting the first to fourth cores 21 to 24 and the insulating member 15 to each other.

The first core 21 to the fourth core 24 are formed so that the area of both end portions 21b is smaller than the area of the spiral portion 21a around which the first to fourth wires 25 to 28 are wound And the outer surface of the insulating member 15 is made to coincide with the insulating member 15.

The reason why the area of the end portion 21b is aligned with the outer surface of the insulating member 15 is as follows. When a current is supplied to the electric wire and the core becomes an electromagnet, the influence of neighboring nodes, .

The first to fourth wires 25 to 28 may pass through the nod 10.

The insulation member 15 is made of a non-ferrous metal or a synthetic resin material. The insertion end 21c formed at both ends of the first core 21 to the fourth core 24 is inserted into both ends of the insulation member 15, (15a) is formed.

In addition, the nodal portion 10 connects the insulating member 15 of the first to n-th nodes 20a to 20n with the first to fourth elastic members 31 to 34.

In the endoscope 100 according to the present invention, the direction of polarity of electric current is differently supplied to one row of the electromagnets facing each other, so that attraction force is generated in each electromagnet to be closely contacted.

The polarities of the currents are equally supplied to the other rows of the electromagnets, so that repulsive forces are generated in the electromagnets, and the nodal portions 10 are deflected.

On the other hand, when the power is cut off to the electromagnet, the electromagnet is restored to the initial position by the elastic force.

In order to operate the endoscope 100 as described above, the first to fourth wires 25 to 28, which are each formed of four pairs of first to n-th segments 20a to 20n, A separate current supply device 200 for supplying a current to the current supply device 200 is provided.

In addition, a control device connected to the current supply device 200 to supply and cut off current, and up / down / left / right buttons 301, 302, 303 and 304 for adjusting the bending direction are formed The operation unit 300 may be configured as an example.

The operation and effect of the present invention constructed as described above will be described below.

1 to 3, in order to use the endoscope 100, an illumination lens for securing a field of view to the interior of the nod 10, an objective lens for capturing an image, air or water Nozzles and the like are inserted through the n-th node 20n so as to be exposed at the tip of the first node 20a.

The first electric wire 25 to the fourth electric wire 28 are connected to the electric current supplying device 200 and the first electric wire 25 is positioned in the first row 10a, The column in which the electric wire 26 is located is the second column 10b, the column in which the third electric wire 27 is located is the third column 10c and the column in which the fourth electric wire 28 is located is the fourth column 10d ), For example.

First, from the first nerve 20a of the endoscope 100, an endoscope is inserted into the body for the purpose of inserting into the inside of the body, the view is secured by the illumination lens, and the image is captured by the objective lens. .

At this time, when the endoscope 100 is introduced into the inside of the body, the nod 20 moves along the guiding wire, which is previously performed, and the first nod 20a through the nth nod 20n are inserted into the first elastic member 31 to the fourth resilient member 34 so as to closely correspond to the bending, thereby facilitating insertion and ejection processes.

When the endoscope 100 is moved to the selected position, the distal end of the endoscope 100 is rotated with the objective lens to accurately check the position of the lesion or the position for later treatment.

As shown in FIGS. 4A to 4C, it is explained that the distal end of the endoscope 100 is bent to the upper portion of the endoscope 100, and the first to nth The first row 20a to the n-th node 20n are bent such that the first row 20a to the ninth row 20n are adjacent to the first row 10a on which the first wires 25 are respectively formed, The side of the second row 10b of the formed second wire 26 is curved so that the first to n-th segments 20a to 20n are spread apart from each other.

When the upper button 301 of the operation unit 300 is operated, current is supplied to the first wire 25 formed on the first node 20a, and the first wire 25 The positive electrode (+) and the negative electrode (-) of the current supplied to the first electric wire 25 formed in the first node 20a are supplied to be opposite to each other.

That is, the positive electrode (+) and the negative electrode (-) of the current are connected to the first wire 25 of the first node 20a, the third node 20c, the fifth node 20e and the seventh node 20g, And the first wire 25 of the second node 20b, the fourth node 20d, the sixth node 20f and the nth node 20n are supplied with the positive polarity of current And the cathode (-) is supplied in the same direction.

The current supplied to the first wire 25 of the first node 20a, the third node 20c, the fifth node 20e and the seventh node 20g causes current to flow through the first core 21 An N pole is formed in a direction in which the magnetic field exits and an S pole is formed in a direction in which the magnetic field exits. The second, second, and third nodes 20b, 20d, 20f, The N pole is formed in the direction in which the magnetic field of the first core 21 is reversed by the current supplied to the first electric wire 25 of the first core 21 and the S pole is formed in the direction of the magnetic field.

Thus, the first node 20a, the third node 20c, the fifth node 20e, the seventh node 20g and the second node 20b, the fourth node 20d, the sixth node 20f And the first cores 21 of the n-th node 20n face each other with an N pole, an S pole, an S pole and an N pole facing each other, and the first cores 21 are attracted by electromagnetic force, .

On the other hand, the positive electrode (+) and negative electrode (-) of the current are supplied in the same direction to the second wire 26 of the first node 20a to the nth node 20n formed in the second row 10b The second core 22 is characterized in that the N-poles, the N-poles, the S-poles and the S-poles are opposed to each other and the second cores 22 generate a repulsive force by electromagnetic force to help the second cores 22 .

Thereafter, when the operation of the upper button 301 is stopped to cut off the current, the first elastic member 31 applies a pushing force and the second elastic member 32 applies a pulling force to the end portion of the endoscope 100 So that the nodal portion 10 is in a straight line.

When the upper button 301 is operated using the operation unit 300, the first to n-th segments 20a to 20n of the first row 10a are pulled by the magnetic force polarities of different electromagnetic forces, And the first to n-th segments 20a to 20n of the second row 10b are pushed and bent by the same magnetic polarity of the electromagnetic force.

5A to 5C, when the left button 303 is operated, the third electromagnet 13 of the third row 10c is operated by the first node 20a, The third cores 23 of the n-th node 20n are attracted to each other by magnetic force polarities different in electromagnetic force from each other and the fourth column 10d on the opposite side is in contact with the first nodal 20a- And the fourth cores 24 of the n-th node 20n are pushed by the magnetic force polarities of the same electromagnetic force.

That is, when one of the up / down / left / right buttons 301, 302, 303 and 304 is operated, the current direction is the same in the electromagnets opposed to the button to be operated, When the left button 303 is operated, the third electromagnet 13 of the third row 10c is operated such that the first to n-th segments 20a to 20n are mutually different in electromagnetic force from each other And the fourth row 10d of the fourth electromagnet 14 in the opposite direction is pushed and bent by the magnetic force polarity and the first nodal 20a to the n-th nod 20n are pushed and bent by the same magnetic polarity of the electromagnetic force , No current is supplied to the first electromagnet 11 of the first row 10a and the second electromagnet 12 of the second row 10b.
