Description

Endoscope system

The present invention relates to an endoscope system using a capsule endoscope device that is introduced into the human body, and more particularly, a capsule endoscope for the purpose of image diagnosis and the like by remotely operating a capsule endoscope introduced into a human organ using magnetic force from outside the human body. The present invention relates to an endoscope system capable of stopping or moving an organ within a human organ.

Conventional capsule endoscopes are equipped with a small battery, a photographing means and a communication means, and when injected into the patient through the oral to move through the esophagus, stomach, small intestine, large intestine until it is discharged out of the body to shoot the walls of the organs they passed A device that transmits a video signal to the outside of a body, and is passively moved by a long-term interlocking movement.

Therefore, there is a disadvantage that it is impossible to stop the endoscope arbitrarily at the site to be observed in detail during the movement, or to go back up the organ in order to observe the site that has passed once.

To solve this problem, Olympus Inc. is propelling the capsule endoscope by helical motion by rotating the capsule endoscope with a permanent magnet and attaching a fixed spiral to its outer shell by an external three-axis stator coil. A patent has been filed for a method of making a patent (European Patent EP1652466A1).

The propulsion method using a fixed spiral like the above patent is effective in straight organs having a certain viscosity. However, since the screw angle is fixed, the performance is greatly deteriorated in organs having a high or low viscosity or a long curvature. Can be.

In particular, when the capsule-type endoscope is rotated in a high-viscosity organ, the endoscope may be attached to the organ, and the organ may be twisted. In this situation, as the endoscope is advanced, the organ becomes more twisted, and further spiral propulsion becomes impossible.

Also, when the endoscope bends to the left and to the right when the capsule endoscope passes through a curved organ, the effective spiral angle is different. If the effective spiral angle is too large in an organ with too high viscosity, the organ may be damaged by excessive frictional force. On the contrary, in a curved organ with low viscosity, if the effective helix angle is too large, slippage occurs, and if it is too small, the propulsion speed is greatly reduced.

In addition, the patent requires the use of a large Helmholz coil of a size that can wrap the human body in applying a rotating magnetic field to rotate the capsule endoscope, such a large electromagnet is very expensive like MRI equipment However, there is a disadvantage in that the installation space is limited by the size.

As a method to solve this disadvantage, the patent filed by the Korea Institute of Science and Technology ("Capsule Endoscope Control System", Korean Patent No. 615881) is equipped with a permanent magnet, a magnetic field sensor and an image module, and a series of signals to the outside of the human body. Medical capsule having a wireless transmission circuit for transmitting a; 2 for rotating the yaw, roll or pitch of an external permanent magnet that exerts a series of magnetic forces with respect to the permanent magnet mounted in the capsule An axial rotation joint part, a photoelectric distance sensor attached to a lower end of the two-axis rotation joint part to measure the distance between the external permanent magnet and the human body surface, and moving the external permanent magnet and the two axis rotary joint part along the fire extinguisher inside the human body. 3-axis Cartesian robot for the support, the bed to support the person to be diagnosed and / or treated, the tilt angle is adjusted in the roll direction, the two-axis rotation It is a bar presenting a capsule endoscope control system comprising a remote control to the control unit that was used to control the driving of the hip and the bed, and a three-axis Cartesian robot moving the body within the capsule to a random position or rotated or stopped.

The present invention is based on the principle of using the magnetic force of the permanent magnet attached to the bottom of the manipulator more than five degrees of freedom from outside the human body to move the capsule endoscope embedded with the permanent magnet mounted in the capsule, the two axes of the manipulator It is also possible to propel a spiral motion by rotating a capsule endoscope equipped with a spiral shell using a rotating joint, so it has more advantages in terms of economics than a large electromagnet, such as Olympus' patent.

However, since only one external magnet is used, the size of the magnet has to be increased in order to rotate the capsule endoscope even at a sufficiently long distance from the human body. On the other hand, if the external magnet pulls the capsule endoscope in the radial direction too large, it may pull the organ and damage the organ, thus detecting the strength of the magnetic force and preventing the distance between the external magnet and the capsule endoscope from approaching a certain level. A safety function is essential.

The present invention induces a spiral motion through the yaw, pitch direction rotation, and roll direction rotation of the capsule endoscope at a sufficient distance without using a large magnet as in the prior art so that the capsule endoscope can move smoothly in the human intestine It is an object of the present invention to provide an endoscope system capable of providing a rotating magnetic field.

The present invention according to a preferred embodiment for solving the above problems, as an endoscope system using a capsule endoscope propelled by the spiral movement in the human organs, which can advance the endoscope through the right screw rotation or left screw rotation A capsule type endoscope having a variable spiral mechanism for forming a spiral protrusion, the capsule type endoscope being inserted into the human body and capturing an internal organ image of the human body; Roll, yaw or pitch a first external magnet that applies magnetic force to the capsule endoscope outside the human body according to a user's operation, or change the position of the first external magnet. First magnetic force applying means capable of being moved or fixed; On the opposite side of the first magnetic force applying means around the human body, a second external magnet for applying a magnetic force to the capsule endoscope in conjunction with the first external magnet to rotate in the roll, yaw or pitch direction, or a second Second magnetic force applying means capable of moving or fixing the position of the external magnet; And measuring positions of the first external magnet and the second external magnet, varying positions of the second external magnet according to the position of the first external magnet, and changing the first external magnet and the second external magnet. Rotating to interlock to generate a rotating magnetic field, the control device for outputting the user's recognition of the internal organ image of the human body taken by the capsule endoscope; includes.

Furthermore, the present invention according to another preferred embodiment, as an endoscope system using a capsule endoscope that is promoted by the spiral motion in the human organs, to form a spiral projection that can advance the endoscope through the right screw rotation or left screw rotation A capsule endoscope provided with a variable spiral mechanism and inserted into the human body to take an image of the organ of the human body; Roll, yaw, or pitch a first external magnet and a second external magnet for applying a magnetic force to the capsule endoscope on both sides of the human body around the human body, or rotating the first external magnet and the second external magnet. Magnetic force applying means capable of simultaneously moving or fixing the positions of the first external magnet and the second external magnet; And controlling the position of the magnetic force applying means according to the control information received from the user, and rotating the first external magnet and the second external magnet in association with each other to generate a rotating magnetic field. It includes; a control device for outputting the image in the organ of the human body so that the user can recognize.

According to the present invention, by generating a rotating magnetic field by using two magnets provided in a symmetrical position with respect to the capsule endoscope, a smaller size to induce a magnetic force of the same size than the conventional technology using only one magnet Magnets can be used.

As such, the magnetic force acting on the capsule endoscope cancels each other through two magnets, thereby preventing the possibility of excessive magnetic force acting in the radial direction of the capsule endoscope to pull the organ.

At this time, even if the magnetic force acting in both directions of the capsule endoscope is not exactly symmetrical, it is very unlikely that excessive magnetic force acts in the radial direction of the capsule endoscope than the conventional technique using a single magnet is very effective in preventing accidents Big.

In addition, even if a magnet on one side does not operate normally due to a failure, if necessary, it may be driven in the same manner as in the prior art using only one magnet.

Furthermore, in the case of the endoscope according to the second preferred embodiment of the present invention, it is not necessary to embed a separate driving device in the capsule endoscope in order to change the advancing direction of the capsule endoscope, thereby miniaturizing the size of the capsule endoscope. It is advantageous in that the power consumption is reduced, so that it can be operated for a longer time.

In addition, since the endoscope according to the second embodiment of the present invention is driven through a simple mechanical principle, there is an advantage that the probability of occurrence of residual trouble is greatly reduced.

Do.

Further, the rotary joint 223a and the vertical slide joint 223b of the horizontal articulated portion 223 may be attached with an electronic, hydraulic, or pneumatic brake to fix the joint at a specific position.

In addition, the braking and releasing of the joint may be performed according to the manual operation of the user through the manipulation handle 225. For example, the user may input a signal for releasing the braking of each joint 223a or 223b. The first external magnet 221 may be manually moved, and when the position of the first external magnet 221 is determined, the brake is applied again to prevent the joints 223a and 223b of the master manipulator 220 from moving any more. After braking, the first external magnet 221 may be rotated in a roll, yaw, or pitch direction through the first motor unit 222 to apply a rotating magnetic field.

Here, the braking and releasing of the joints 223a and 223b of the master manipulator 220 are described as being made through the manipulation handle 225. However, the present invention is not necessarily limited to a separate remote controller (not shown). Braking and releasing are also possible.

The position of 231 is automatically moved.

Through such a configuration, the present invention enables the first external magnet 221 and the second external magnet 231 to be interlocked to form a rotating magnetic field even when the user operates only the master manipulator 220. At this time, the position of the first external magnet 221 and the second external magnet 231 is preferably output so that the user can recognize through the control unit 240 so that the user can refer to it.

On the other hand, the endoscope system 200 of the present invention according to a preferred embodiment may further include a swivel chair 250, such a swivel chair 250 as shown in Figures 2 and 4 back 251 The slave manipulator 230 is provided at the rear side of the) so that the human body 1 can be easily exposed to the rotating magnetic field generated through the master manipulator 220 provided at the front and the slave manipulator 230 at the rear.

At this time, the swivel chair 250 is also preferably capable of rotation in the roll direction by the angle adjustment of the backrest 251 and the chair rotation axis 252.

Hereinafter, a detailed configuration of the steering apparatus 240 will be described with reference to FIG. 5.

The steering unit 240 is a magnetic position measuring unit 245 of the first external magnet 221 and the second external magnet 231 from the results measured by the rotation angle sensor (A) and displacement sensor (B) Measure the position.

In addition, the magnet position measuring unit 245 calculates position change data necessary for the second external magnet 231 to move to a position (symmetrical) corresponding to the first external magnet 221, and the slave manipulator control unit 247. ) Controls the slave manipulator 240 according to the position change data.

In this case, it is also possible to change the driving of the slave manipulator 240 according to a manual command input through the user input unit (manual command input unit).

In addition, the magnet rotation command unit 244 controls the first and second motor units 222 and 232 when a signal for whether the first or second external magnets 221 and 231 are rotated is transmitted from the operation handle 225. Thereby rotating or stopping the first and second external magnets 221 and 231.

The wireless transmitter / receiver 241 is for wireless communication with the capsule endoscope 210 and the image information transmitted from the capsule endoscope 210 and the direction and intensity of the magnetic force acting from the outside of the capsule endoscope 210 Receive information.

The received information is transmitted to the indicating unit 242 so that the user can recognize it, and information about the direction and intensity of the magnetic force is also transmitted to the endoscope position detecting unit 243 and used to detect the position of the endoscope. .

In addition, the position of the endoscope detected by the endoscope position detecting unit 243 may also be output to the user through the indicating unit 242 so as to be recognized.

On the other hand, when the wireless transmission and reception unit 241 receives a fixed command signal for the rotary ring from the operation handle 225, it is transmitted back to the capsule endoscope 210 by the capsule endoscope 210 corresponds to the fixed command signal In this direction, the fixing projections to be described later can be ejected.

Referring to the operation of the endoscope system 200 of the present invention according to a preferred embodiment having such a configuration as follows.

First, by operating the operation handle 225 (preferably the magnet rotation switch included in the operation handle 225), if the first external magnet 221 is selected to rotate in the clockwise direction, the magnet rotation of the control unit 240 The command unit 244 generates a rotating magnetic field in the capsule endoscope 210 while the first external magnet 221 rotates in the clockwise direction and the second external magnet 231 rotates at a constant speed in the counterclockwise direction.

On the contrary, the first external magnet 221 rotates in the counterclockwise direction, and the second external magnet 231 rotates in the clockwise direction.

When the capsule endoscope 210 starts the spiral movement, the user views the position of the first external magnet 231 by using the manipulation handle 225 while watching the image transmitted from the capsule endoscope 210 through the indicator 242. Move along the organ.

In this case, the second external magnet 231 is positioned so that the center of the first external magnet 221 is positioned on the center line perpendicular to the axis of rotation of the second external magnet 231 by the slave manipulator controller 247 of the control unit 240. Always move automatically.

If you want to change the direction of the spiral during the movement of the capsule endoscope 210 to change the direction of rotation of the two external magnets (221, 231), if you want to change the direction of movement of the capsule endoscope 210 is to change the position of the fixing projections.

In addition, in the case of using the capsule endoscope 310 according to the second embodiment of the present invention, there is no need to change the position of the fixing protrusion so that the two end magnets are moved to the direction in which the capsule endoscope 310 is to be moved, and then rotated. By doing this, the same effect can be derived.

If you want to stop the movement of the capsule endoscope 210 may stop the rotation of the two external magnets, and can operate the joint brake so that the joint of the master manipulator 220 does not move.

When the diagnosis is completed, the first external magnet is reversed from the human body and the second external magnet is sent to the bottom to release all magnetic force acting on the capsule endoscope, and the capsule endoscope is discharged to the body after a certain time by the digestive exercise. do.

Endoscope system 200 of the present invention according to a preferred embodiment is to move in the direction desired by the user of the system 100 in any direction to rotate the capsule endoscope 210 orally injected into the human body through the configuration as described above It can be used without side effects such as twisting of the organ, and furthermore, since it does not require a configuration such as a large Helmholtz coil, there is little space constraint and the organ can be prevented from being damaged by excessive magnetic force.

Hereinafter, the configuration of the capsule endoscope 210a according to the first embodiment of the present invention will be described in more detail with reference to FIG. 6.

As shown in FIG. 6, the capsule endoscope 210 includes a permanent magnet 213 magnetized perpendicular to the rotation axis direction, in addition to the image sensor, the second wireless communication unit 211, and the battery 212.

The image sensor and the second wireless communication unit 211 are used to photograph images of organs in the human body and wirelessly transmit them to the outside.

The battery 212 supplies the power required for each component within the capsule endoscope 210 to operate.

The permanent magnet 213 is used to impart magnetism to the capsule endoscope. The permanent magnet 213 may be divided into two and disposed before and after the battery 212, or one magnet may be disposed before or after the battery 212.

A variable spiral mechanism 214 is attached to the envelope of the capsule endoscope 210 according to the first embodiment of the present invention as shown in FIG. 7.

The variable spiral mechanism 214 includes at least one pair of rotary rings 214a and slidably rotatable about an axis formed in the longitudinal direction of the capsule endoscope 210 and at least one pair of rotary rings 214a. Interposed between the plurality of blades 214b connecting each other, and at least one pair of rotation rings 214a, and when a fixed command signal is received from the control unit 240, at least one pair of rotations according to the fixed command signal. It is configured to include an intermediate jaw (214d) having a fixing projection (214c) for injecting in one direction of the ring (214a) to selectively fix one side of the at least one pair of rotating ring (214a).

Through the above structure, the capsule endoscope 210 rotates at least one pair according to the direction information included in the fixed command signal when the fixed command signal is received from the control unit 240 through the second wireless communication unit 211. One side of the ring 214a is fixed.

In more detail, as shown in Figs. 7 (a) to 7 (f), in the capsule endoscope of the present invention according to the first preferred embodiment, at least a pair of rotary rings 214a face each other with a triangular or A trapezoidal protrusion end 214e is formed, and the fixing protrusion 214c is in one direction of at least one pair of rotation rings 214a by the fixing protrusion driving unit 215 according to the fixing command signal (FIG. 6 (a)). Is injected to the left) to selectively engage and secure the protrusion end 214e of one side of the at least one pair of rotary rings 214a.

Then, when a magnetic field is applied from the outside, the non-fixed side of the at least one pair of rotating rings 214a is twisted by the frictional force with the organ, and thus the blade 214b forms a spiral. As shown in 7 (e), the capsule endoscope moves while turning the right screw or left screw.

That is, in the capsule endoscope 210 of the present invention according to the first preferred embodiment, the advancing direction of the capsule endoscope 210 is determined according to the direction in which the fixing protrusion 214c is injected, and continues in one direction even if the rotation direction is changed. In order to move forward, the doctor may arbitrarily select the rotational direction of the capsule endoscope 210 according to the curvature or viscosity of the organ.

By using this principle, the present invention, when the capsule endoscope 210 is adhered to the organs and the organs may be twisted, the capsule endoscope 210 is driven without changing the organs by twisting the left screw rotation and the right screw rotation. You can keep moving forward.

Although the above description has been described only in the case where the fixing projection 214c is injected to the left, it can be equally applied to the case in which the fixing protrusion 214c is injected to the right as shown in Figs. have.

Here, the rotary ring 214a and the middle jaw 214d may be provided with two or more as shown in FIG. 8.

In addition, the capsule endoscope 210 may further include a magnetic sensor 215, the magnetic sensor 215 is to detect the direction and intensity of the magnetic force acting from the outside to the capsule endoscope 210, Information about the direction and intensity of the magnetic force detected by the magnetic field sensor is wirelessly transmitted through the second wireless communication unit 211 together with the image signal.

The information on the direction and intensity of the magnetic force transmitted as described above is used to detect the position of the capsule endoscope 210 introduced into the human body in the control unit 240 as described above.

Hereinafter, the capsule endoscope 310 according to the second embodiment of the present invention will be described with reference to FIGS. 9 (a) to 9 (g).

The capsule endoscope 310 of the present invention according to the second preferred embodiment has the same configuration as the capsule endoscope 210 of the present invention according to the first preferred embodiment, but the configuration of the variable spiral mechanism 314 is the same. This is done differently.

Variable spiral mechanism 314 of the capsule endoscope 310 of the present invention according to the second embodiment, at least one is provided to be slidably and rotatable about an axis formed in the longitudinal direction in the body of the capsule endoscope 310 A plurality of blades 314b connecting the pair of rotary rings 314a, at least one pair of rotary rings 314a with each other, and an intermediate jaw 314c interposed at a fixed position between the at least one pair of rotary rings At least one pair of rotating ring 314a and the intermediate jaw 314c are in contact with each other, the trapezoidal or triangular projection end (314d, 314e) is formed in accordance with the direction of the magnetic force applied from the outside The pushing direction of the capsule endoscope 310 is automatically determined.

In more detail, if the first and second external magnets 221, 231 are in front of the capsule endoscope 310, the two rotating rings 314a and the blades 314b are adhered to the organ wall by the frictional force. In the state only the body of the capsule endoscope 310 is drawn by the magnetic force to move forward, as shown in Figure 9 (b) of the rotating ring of the front side of the two rotary rings 314a through the projection end (314d, 314e) intermediate jaw 314c ) Will be combined.

In this state, when the first and second external magnets 221 and 231 are rotated, the capsule endoscope 310 is rotated while the rotary ring on the rear side is released, so that the blade 314b is twisted by the frictional force of the long-term wall to form a spiral. do. The spiral direction may be a right screw or a left screw as shown in FIG. 9 (d) or 9 (f) according to the rotation direction of the capsule endoscope 310, but the capsule endoscope always moves forward.

On the contrary, when the first and second external magnets 221 and 231 are behind the endoscope 310, the two rotating rings 314a and the blades 314b are moved by the magnetic force only by the body while the two rotary rings 314a and the blades 314b are adhered to the organ wall by the frictional force. At the same time, as shown in FIG. 9 (c), the rear ring rotates with the intermediate jaw. In this state, when the external magnet is rotated, the capsule endoscope 310 rotates while the front rotary ring is released, so that the blade 314b is twisted by the frictional force of the long-term wall to form a spiral.

The direction of the spiral is to rotate the right screw or left screw as shown in Fig. 9 (e) or 9 (g) according to the rotation direction of the capsule endoscope, the capsule endoscope will always move only backward.

That is, the moving direction of the capsule endoscope is automatically determined depending on whether the first and second external magnets 221 and 231 are located in front of or behind the capsule endoscope 310. Therefore, a separate drive device for fixing the rotary ring in the endoscope does not need to be built separately, which has the advantage of simplicity, and the capsule endoscope can be easily moved without considering the direction of the fixing protrusion 214c. As a result, operation is also simplified.

At this time, the capsule endoscope 310 according to the second embodiment of the present invention may also be provided with two or more rotation rings 314a and the middle jaw 314c as shown in FIG. 10.

On the other hand, with reference to Figure 11 will be described in the endoscope system according to another embodiment of the present invention. In the description, the same reference numerals as those in Figs. 1 to 10 refer to the same components that perform the same function.

As shown in FIG. 11, the endoscope system 400 of the present invention includes a capsule endoscope 210, a magnetic force applying means 420, and a steering device 440.

Endoscope system 400 of the present invention according to another preferred embodiment is a magnetic force capable of simultaneously moving or fixing the position of the first external magnet 421 and the second external magnet 422, as shown in FIG. The means 420 is used.

Here, the magnetic force applying means 420 is a C-type manipulator as shown in Figure 12, the front and rear left and right sides of the position of the C-shaped frame 427, the two degree of freedom rotating joint 428 and the two degree of freedom rotating joint 428 It is largely divided into planar slide joints 429 for translational motion.
