Specification

Capsule endoscope cleaning device

Technical field

[0001] The present invention relates to a cleaning device for cleaning a capsule endoscope excreted outside the body.

Background art

A known endoscope apparatus includes a tubular insertion portion having an imaging element or the like at the tip, an operation portion connected to the insertion portion by a flexible tube, an image processing device, a display device, and the like. The insertion portion is inserted into the body of the subject and photographed, and the desired site in the body is displayed on the display device, so that the desired site can be observed and inspected. However, in such an endoscope apparatus, there is a problem that the subject suffers pain because the flexible tube connected to the insertion portion passes through the throat of the subject while observing the inside of the body. Also, due to the thickness, length, and complicated shape of the insertion section, only skilled doctors and medical technicians could operate the device, observe and inspect.

In view of such circumstances, an ultra-small endoscope in which a flexible tube is continuously provided and a solid-state image pickup device having a photographing optical system or the like is housed inside a capsule-shaped main body, so-called A capsule endoscope is provided (see Patent Document 1). The capsule endoscope has wireless communication means for transmitting image data captured in the body from the body, and transmits the captured image data to a display device isolated from the capsule endoscope force to display the organ data. It is possible to conduct inspections and inspections. This capsule endoscope keeps taking images of the body of the subject until it is inserted from the subject's throat and excreted from the anus. Inspection is easy and can be expected.

[0004] By the way, in recent years, if a capsule endoscope that has been excreted outside the body after being examined is discharged into the sewer as it is, the risk of leaking image data inside the subject's body and the natural environment will be contaminated. There is a growing need to collect excreted capsule endoscopes. In addition, when using a capsule endoscope with a function of collecting a lesion in the body and storing the lesion inside, remove the lesion from the excreted capsule endoscope. Because it is necessary to take out, it must be collected.

[0005] Therefore, a grid-like collecting means is installed in the puddle of the toilet so as to close the drainage groove for collecting the excreted capsule endoscope, and the capsule excreted by the collecting means A method of locking and collecting the endoscope has been proposed (see Patent Document 2). Since the stool adheres to the capsule endoscope locked by the collecting means, water is poured into the toilet bowl, and the stool adhering to the water is washed and collected.

Problems to be solved by the invention

[0006] However, in order to clean the stool adhering to the capsule endoscope neatly with the above-described prior art, it is not sufficient to once flush the toilet with water. In a single cleaning, the capsule endoscope itself is not cleaned cleanly by cleaning the inside of the puddle, so at least two cleanings are necessary. In particular, cleaning methods using the siphon principle such as the siphon type and siphon set type, which have been used recently, place emphasis on sucking stool into the drainage channel, washing it, and flowing it. It was difficult to clean the locked capsule endoscope cleanly. Therefore, for the subject who collects the capsule endoscope, if this cleaning operation becomes complicated, it is necessary to flow water many times with a force. If the water is wasted, a problem arises.

[0007] The present invention has been made in view of the above-described points, and an object of the present invention is to reliably clean the capsule endoscope collected by the collecting means and save water. It is an object of the present invention to provide a capsule endoscope cleaning apparatus capable of performing the above.

FIG. 1 shows a configuration of a capsule endoscope apparatus and the like as an example of the present invention, and FIG. 2 is a cross-sectional view showing an internal configuration of the capsule endoscope shown in FIG.

As shown in FIG. 1, the capsule endoscope apparatus 1 for performing endoscopy according to the present invention is placed in a body cavity duct when passing through the body cavity duct by being swallowed from the mouth of a subject 2. A capsule endoscope 3 that wirelessly transmits an image signal obtained by optically imaging the wall surface and a signal transmitted by the capsule endoscope 3 are received by the antenna unit 4 provided outside the body of the subject 2, and the image is stored. And an extracorporeal unit 5 (located outside the subject 2).

[0015] The extracorporeal unit 5 contains a small memory card such as a contact flash (registered trademark) having a capacity of, for example, 1 GB in order to store image data. [0016] The image data stored in the extracorporeal unit 5 can be connected to the display system 6 during or after the examination to display an image.

That is, the extracorporeal unit 5 is detachably connected with a personal computer (hereinafter abbreviated as a personal computer) 7 constituting the display system 6 and a communication cable such as a USB cable 8.

[0018] Then, the image stored in the external unit 5 is captured by the personal computer 7 and stored on the internal hard disk or displayed, and the stored image can be displayed on the display unit 9. . For example, a keyboard 10 is connected to the personal computer 7 as an operation panel for performing data input operations.

[0019] The USB cable 8 may be any communication standard of USB 1.0, USB 1.1, and USB 2.0. In addition, it may be one that performs serial data communication in accordance with RS-232C and IEEE1394 standards, or one that performs parallel data communication that is not limited to one that performs serial data communication.

[0020] An antenna unit 4 to which a plurality of antennas 12 are attached is attached to the inside of a shield shirt 11 having a shield function worn by the subject 2. When performing endoscopy, the image data captured by the capsule endoscope 3 is also transmitted to the antenna unit 4 through the transmission / reception antenna force incorporated in the capsule endoscope 3, and connected to the antenna unit 4. Stored in the extracorporeal unit 5. The extracorporeal unit 5 is attached to the belt of the subject 2 by a detachable hook, for example.

The extracorporeal unit 5 includes a transmission / reception circuit (communication circuit), a control circuit, an image data display circuit, and a power source.

[0022] As shown in FIG. 2, the outer shape of the capsule endoscope 3 is an outline of a small egg shape so that it can be quickly moved in the upper and lower digestive tracts. A substantially oval shape is preferable, but it may be a spherical shape or a ratterby ball type.

[0023] The capsule endoscope 3 includes a transparent front wall portion 21 having a substantially hemispherical front end side, a rear wall portion 23 having a substantially hemispherical rear end side, a front wall portion and a rear wall portion. To fit inside The outer shape is formed by a fitting member 22 that forms a water-tight capsule having a watertight structure.

[0024] Inside the capsule endoscope 3, there are an objective lens 31, an observation optical system 32, an illumination optical system 33, a storage room 34, a capacitor 35, a receiver 36, a transmitter 37, and a wireless transmission / reception antenna 38. It is stored. These parts are integrally attached by a base not shown.

[0025] The imaging device that constitutes the observation optical system 32 is a device that converts a captured in-vivo image into an electrical signal, and a fine CCD or CMOS, etc. in which one pixel is arranged at intervals of 0.1 μm to 3 μm. Individual image sensors are used.

[0026] The objective lens 31 is a lens for forming an observation image on the image sensor of the observation optical system 32. For example, the objective lens 31 includes a single or a plurality of spherical lenses or aspherical lenses. The objective lens 31 is preferably an aspherical lens rather than a spherical lens! When an aspheric lens is used, the number of objective lenses can be reduced, so that the total length of the capsule endoscope 3 can be shortened and swallowability and excretion can be improved.

[0027] As the illumination elements constituting the illumination optical system 33, white, green, and red light emitting diodes (hereinafter also referred to as LEDs) are commonly used.

[0028] The illumination light that has also been emitted by the illumination element force is emitted through the transparent front wall 21 of the capsule endoscope 3 into the photographing field of view to illuminate the inside of the photographing field of view. The image sensor images the illuminated field of view through the objective lens 31. A signal photographed by the image sensor is converted into an image signal by a signal processing circuit (not shown), and then transmitted to the external extracorporeal unit 5 by the transmitter 37 and the transmitting / receiving antenna 38. The image data stored in the extracorporeal unit 5 is connected to the display system 6 in FIG. 1 during the examination or after the examination is completed, and an image is displayed. This makes it possible to observe and examine the organ of the subject.

[0029] The capacitor 35 functions as a power source for each element and circuit, and may be driven by a hospital power source, a household power source, a solar cell, a fuel cell, or the like, or may be transmitted from the outside. A transformer that converts a sound wave, a magnetic field or an electric field into a power source may be used.

When the subject 2 holds a stool at the time when the capsule endoscope 3 reaches the anus, as shown in FIG. 3, the stool is excreted by the toilet with the collecting means 45 disposed therein. The capsule endoscope 3 is excreted along with the excretion of the stool and is locked by the collecting means 45. The locked capsule endoscope 3 is recovered after being cleaned by a cleaning means 50 described later.

[0035] The collecting means 45 includes a net part 46 for locking the excreted capsule endoscope 3, and a strip-shaped handle part 47 having one end connected to the net part 46. The net 46 is arranged so as to block the drainage groove 43 of the toilet 40, and a handle 47 having one end connected to the net 46 extends upward along the inner surface of the toilet 40, and outwards at the upper edge. The collecting means 45 can be folded so that it can be easily installed in the toilet bowl 40 by folding it.

It should be noted that the collection means 45 is configured so that the locked capsule endoscope 3 is immersed in the puddle 42 of the toilet bowl 40. It is installed at the top of the puddle 42 so that there is no such thing. By installing in this way, the cleaning liquid discharged from the cleaning means 50 is not obstructed by the water in the puddle 42.

[0037] The net 46 is formed in a checkered pattern so that water, endocrine secretions and excretion discharged from the body can be separated. The mesh interval of the mesh part 46 is preferably 20% to 97% of the dimension of the short axis length b of the capsule endoscope 3! /. If it is 97% or less, the capsule endoscope 3 can be reliably collected, and if it is 20% or more, the space part of the mesh part 45 becomes an appropriate size and drops excreted feces into the puddle 42. Can do. More preferably, it is 50% to 90%. The mesh of the net 46 may be a vertical stripe instead of a lattice.

[0038] Further, as shown in FIG. 4, it is preferable that the shape of the net portion 46 is a bowl shape in which the central portion is recessed. By having such a shape, the capsule endoscope 3 excreted outside the body is locked at the center portion recessed by gravity, so that the capsule endoscope 3 can be easily cleaned by the cleaning means 50 described later. Become.

FIG. 5 is a cross-sectional view of the tip portion of the cleaning means 50 used in the present invention. The cleaning means 50 will be described with reference to this figure.

[0040] The capsule endoscope 3 locked on the mesh part 46 is washed by the washing means 50 connected to the drying surface 41 of the toilet bowl 40 (see Fig. 4). The cleaning means 50 supplies cleaning liquid from a cleaning liquid tank (not shown) inside the toilet bowl 40, guides the cleaning liquid through the flow path 51, and discharges the cleaning liquid from the discharge hole 52 toward the capsule endoscope 3 on the net 46. To do.

[0041] By reducing the area of the discharge hole 52 and providing a plurality of the discharge holes 52, it is possible to discharge the shower-like cleaning liquid. Further, by changing the position and the angle at which the discharge holes 52 are provided, for example, a uniform cleaning liquid can be discharged so as to be concentrated at one point, or can be discharged so as to spread over the entire surface of the collecting means 45.

[0042] As shown in FIG. 6, the flow path 51 is preferably formed with a spiral groove. By forming this groove, the cleaning liquid vortexes and discharges from the discharge hole 52. Therefore, the capsule endoscope 3 locked to the collecting means 45 is rotated by the flow of the cleaning liquid vortex, and the capsule endoscope The entire mirror 3 can be cleaned.

[0043] The cleaning means 50 only needs to be made of a material that does not react with the cleaning liquid. For example, polyethylene resin, nylon resin, polypropylene resin, polyimide resin, polyethylene resin In addition to synthetic resins such as phthalate resin, liquid crystal polymer, aromatized polyamide resin, polyethylene naphthalate resin, polysulfone resin, etc., it is possible to use metal materials such as stainless steel.

[0044] Although not shown, the drying surface 41 of the toilet bowl 40 is provided with a groove for storing the cleaning means 50, so that an external force communication means or an operation means connected to the cleaning means 50 can be operated. By doing so, the cleaning means 50 can be activated and stored. With this configuration, the subject can excrete stool without worrying about the cleaning means 50. Further, the cleaning means 50 is moved like a swing motion by the communication means or the operation means, and the discharge direction of the cleaning liquid can be arbitrarily changed. Although the capsule endoscope 3 is locked at which position of the collection means 45, the capsule endoscope 3 can be reliably cleaned by changing the discharge direction of the cleaning liquid. Can do.

It is also possible to improve the cleaning power by providing a known ultrasonic generator at the tip of the cleaning means 50 and applying ultrasonic vibration to the cleaning liquid to be discharged.

[0046] Further, it is preferable to provide a reflector that reflects the cleaning liquid discharged from the cleaning means 50 between the collection means 45 and the puddle of the toilet bowl 40. Since the cleaning liquid is reflected by the reflecting plate, the side of the collected capsule endoscope 3 that is in close contact with the collecting means 45 can be washed. The reflector may be made of a material that does not react with the cleaning liquid and may be made of the same material as the cleaning means 50 described above.

[0047] The cleaning liquid discharged from the cleaning means 50 is preferably composed of a material that has a detergency and does not adversely affect the environment. Therefore, carbonates such as sodium carbonate, sodium bicarbonate, and sodium percarbonate A washing solution is composed of at least one of the compounds. As the total amount of carbonate, preferably those containing a range of 1 mol / L from 1 X 10- ² mol / L.

[0048] It is preferable to add a surfactant in order to further improve the detergency. The type of the surfactant is a non-ionic or ionic surfactant, and is preferably one that is easily decomposed in the natural environment. Specifically, there are the following powers that are not particularly limited to these.

[0049] Nonionic surfactants include sorbitan fatty acid ester, glycerin fatty acid ester, decagrin fatty acid ester, polyglycerin fatty acid ester, propylene glycol 'Pentaerythritol fatty acid ester, polyoxysorbitan fatty acid ester, polyoxyethylene sorbit fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyethylene glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, poly Oxyethylene / polyoxypropylene, block polymer, polyoxyethylene alkyl phenyl ether, acetylene glycol, polyoxyethylene castor oil, hydrogenated castor oil, polyoxyethylene lanolin, lanolin alcohol, polyoxyethylene alkylamine, fatty acid amide, polyoxyethylene Fluorine series such as alkylphenol formaldehyde condensate and polyoxyethylene perfluoroalkyl There is an active agent, and the like.

[0050] Examples of the cationic surfactant include alkyl sulfates, polyoxyethylene alkyl sulfates, N-acyl amino acids and salts thereof, N-acylmethyl taurate, dialkyl sulfosuccinates, sulfosuccinates. Acid monoester disodium, N-alkylsulfosuccinic acid monoamide, polyoxyethylene alkyl ether acetate, alkyl sulfocarboxylate, a-olefin sulfonate, alkyl phosphate, polyoxyethylene alkyl ether phosphate, etc. There is.

[0051] Polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene, polyoxypropylene, block polymer, which is a generic term for nonionic polyoxyalkylene alkyl ether as a surfactant. Etc. are preferable in terms of effects. The content of the surfactant in the cleaning liquid is preferably in the range of 0.01 to 10% by mass, particularly preferably in the range of 0.05 to 5.0% by mass. By setting it within this range, the viscosity of the cleaning agent is lowered and the fluidity in the cleaning means 50 is improved, so that a good cleaning effect is exhibited.

[0052] Further, a sterilizing agent can be added to the cleaning liquid. As the sterilizing agent, alcohols such as ethanol and isopropyl alcohol, quaternary ammonium salts such as benzalkonium chloride, cresol, sodium hypochlorite and the like can be used. The amount used, concentration, etc. can be referred to the formulation introduced in the handbook. The content of the sterilizing agent in the cleaning solution is preferably in the range of 0.01 to 10% by mass, and more preferably in the range of 0.05 to 5.0% by mass. Next, the capsule endoscope 3 that has been locked by the collecting means 45 and then cleaned by the cleaning means 50 can be stored and stored by the sampling means 60 shown in FIG. it can. The sampling means 60 includes a lid 61 that can be opened and closed, a magnetic field generating member 62 for storing with magnetic force, and a holding part 63. The magnetic field generating member 62 can be arbitrarily selected such as a bright magnet, a neodymium bond magnet, a samarium coronate magnet. The strength of the magnetic field is preferably ImT (T is Tesla) to lOOOmT. By setting the strength of the magnetic field within this range, the capsule endoscope 3 can be smoothly collected and taken out after storage.

In order to make the magnet respond, it is necessary to provide a magnetic metal in the capsule endoscope 3. Although magnetic metal can be used for the battery 35 and circuit members of the Pussel Endoscope 3, magnetic materials with a strong magnetic force have been developed by nanotechnology in recent years. The body can be placed at any position inside the capsule endoscope 3. It is important to install the magnetic field so that it does not interfere with the communication means inside the capsule endoscope or outside the human body.

In order to arrange such a magnetic body inside the capsule endoscope 3, the magnetic field should not interfere with the operation of the observation optical system 32, the receiver 36, the transmitter 37, the wireless transmission / reception antenna 38, etc. It is necessary to. Arranging in the vicinity of the antenna is preferably arranged farther than the position of the antenna. In addition, it is preferable to use magnetic shielding so that the calculation processing function of imaging communication is not impaired.

Here, an inspection process for inspecting a lesion in the upper and lower extinguishers using the capsule endoscope 3 will be described.

[0057] Subject 2 swallows capsule endoscope 3 with a small amount of water. The swallowed capsule endoscope 3 moves to the lower part of the upper force of the extinguisher according to the peristaltic movement of the subject 2. Meanwhile, the inside of the subject 2 is imaged at regular intervals, and the captured image is transmitted to the external unit 5. In some cases, the capsule endoscope 3 collects the lesion of the subject 2. When the capsule endoscope 3 reaches the anus (approximately 8 to 10 hours after swallowing), the subject excretes the stool in the toilet 40 in which the collecting means 45 and the cleaning means 50 are installed. The capsule endoscope 3 excreted together with the stool is locked to the net 46 by the collecting means 45. The cleaning liquid from the cleaning means 50 is jetted onto the locked capsule endoscope 3 and is collected after being disinfected and cleaned. [0058] The doctor causes the display system 6 to display an image of the inside of the subject 2 stored in the extracorporeal unit 5, and takes out a pathological part collected from the collected capsule endoscope 3 for observation and inspection.
