As shown in fig. 1, in a first aspect, embodiments of the present application provide an endoscope comprising:

the body 11 is of a hollow structure and is provided with an inner cavity; the main body 11 is a main structure of the endoscope 1 and is configured to be inserted into the eustachian tube, the external auditory canal, the tympanic membrane, and the middle ear in the ear.

The magnetofluid outer film 12 is coated on the outer periphery side of the body 11; the outer magnetic fluid film 12 can deform in the magnetic field generated by the electrified coil, and the outer magnetic fluid film 12 can generate a peristaltic effect by enabling different positions of the outer magnetic fluid film 12 to be in the magnetic field, so that the body 11 is driven to generate displacement. For example, when the endoscope 1 is used for examination in the ear, the magnetofluid outer film 12 is made of a flexible material, so that the magnetofluid outer film 12 can protect the ear from being damaged even when moving in the ear. And because the magnetic fluid outer film 12 is controlled to deform by controlling the position of the magnetic field, the creeping of the magnetic fluid outer film 12 is realized to drive the body 11 to move in the ear, the damage to the ear canal or the tympanic membrane caused by misoperation when the traditional endoscope 1 needs to be operated by a doctor by hands is avoided, and the safety of a patient when the endoscope 1 is used is further protected.

A plurality of micro coils 13 are arranged on the imaging pipeline 14 at intervals corresponding to the magnetic fluid outer film 12, and each micro coil 13 can be independently electrified; the micro coils 13 are arranged in the inner cavity, each coil can be independently electrified according to requirements, and the magnetic field generated by the micro coils 13 after being electrified is utilized to interact with the magnetic fluid outer film 12, so that the magnetic fluid outer film 12 is deformed. For example, the plurality of micro-coils 13 are sequentially energized along the axial direction of the body 11, so that the magnetofluid outer film 12 can creep in a specified direction, thereby driving the body 11 to a specified position.

An imaging tube 14, the imaging tube 14 being fixed in the inner cavity along an axial direction of the body 11, the imaging tube 14 being configured to have an illumination and photographing function; when the endoscope 1 of the present application is used, the environment in the ear is dark and narrow, and therefore, the imaging tube 14 is required to illuminate the ear, and only shooting and recording can be performed. After the imaging tube 14 illuminates the ear, the condition in the ear is photographed and recorded, the photographed image is transmitted to the display, and a doctor can diagnose or treat the disease of the patient through the real image on the display. The doctor need not manual operation endoscope 1, can obtain the image in the patient's ear, has reduced because doctor's misoperation causes the condition of secondary damage in the ear.

When the plurality of micro coils 13 are sequentially electrified, the regions of the magnetic fluid outer film 12 corresponding to the electrified micro coils 13 sequentially creep. Specifically, during the treatment, the doctor only needs to put the endoscope 1 of the present application into the ear of the patient, and activate the imaging tube 14, and the image in the ear at that time can be displayed on the display. The controller 2 controls the direction of the endoscope 1 moving in the ear, for example, the endoscope 1 needs to move forward, and the controller 2 is controlled to sequentially light up the plurality of micro-coils 13 along the first direction, so that the corresponding magnetic fluid outer membranes 12 can creep along the first direction, and the body 11 and the imaging tube 14 are driven to move forward in the ear. If the endoscope 1 needs to retreat in the ear, the controller 2 is operated to enable the micro coils 13 to sequentially light up along the second direction, and the corresponding magnetic fluid outer film 12 can creep along the second direction, so that the body 11 and the imaging pipeline 14 are driven to retreat in the ear.

Specifically, the eustachian tube, as an independent organ, is an anatomical passageway that communicates the nasal cavity, the pharyngeal cavity, and the middle ear cavity, and has two openings, one opening leading to the tympanum of the middle ear, and the other opening to the nasopharynx. The eustachian tube plays important roles in the human body, such as balancing the middle ear cavity and the external air pressure, draining secretions or dropsy in the middle ear cavity, preventing retrograde infection, blocking sound or silencing and the like. The eustachian tube can be divided into two parts according to anatomical positions, wherein one part is a bone part which is close to the middle ear, a bony structure is arranged around the tube cavity, and the tube cavity is not expandable; the other part is a cartilage part which is close to the nasopharynx part, soft tissue structures such as cartilage, fat and the like are arranged around the tube cavity, and the tube cavity of the eustachian tube is corrugated, and the inside of the tube cavity has certain expansibility. The mucosa covered on the surface of the eustachian tube is the same as the respiratory tract system and is also the cilium mucosa system, the eustachian tube is in a closed state under the normal state of the eustachian tube, but the eustachian tube is positioned at the skull base and is surrounded by a plurality of bony structures, great vessels and muscle structures, and the structure is deeper, so that the eustachian tube part is difficult to be inspected or sampled under direct vision by the conventional means due to the anatomical structure.

Normally, the eustachian tube is in a closed state and may be pathologically occluded or abnormally opened. The children's eustachian tube is short, wide and high in level, and is easy to infect in a retrograde manner to cause otitis media, and the cilium mucosa of the eustachian tube lumen covers in the folds of the eustachian tube lumen, so that the children's eustachian tube is different from the cilium mucosa of other respiratory systems in unique parts. Its lumen lacuna is narrow, mainly presents the closed condition under the physiological state, and whether unobstructed in the lumen is mainly paid close attention to the inspection of eustachian tube function in the tradition, nevertheless lack among the prior art and examine equipment and realize inspection and pathological study to the eustachian tube.

Endoscope 1 in the embodiment of this application then can be fine inspects the eustachian tube, and endoscope 1 can get into the human body through oral cavity or nasal cavity, and it makes magnetic fluid adventitia 12 deformation wriggling to the circular telegram of microcoil 13, can make endoscope 1 remove in oral cavity or nasal cavity, and until the endoscope reachs eustachian tube department, make comparatively comprehensive observation to the eustachian tube through imaging tube 14, and the doctor of being convenient for makes the judgement to the condition of eustachian tube, and then carries out subsequent treatment.

Optionally, the imaging conduit 14 includes a guiding fiber 141 and an illuminating fiber 142, the body 11 has a head end and a tail end, the guiding fiber 141 and the illuminating fiber 142 extend from the tail end to the head end, and the shooting direction of the guiding fiber 141 and the illuminating direction of the illuminating fiber 142 are both toward the head end. When the endoscope 1 is used for examining or treating a patient, the head end of the body 11 is firstly placed into the auditory canal, and the endoscope 1 is sequentially placed into the auditory canal until the tail end of the body 11 enters the auditory canal. The doctor can choose to turn on the illumination fiber 142 and the guide fiber 141 in advance before placing the endoscope 1 in the ear canal, illuminate the ear canal through the illumination fiber 142, and photograph and transmit the scene in the ear canal through the guide fiber 141.

If sick in the patient's ear is located the external auditory canal outside, need not to put endoscope 1 into the duct entirely and can realize the inspection, the doctor can select to open alone illumination optic fibre 142 so that the visibility of external auditory canal improves this moment, the doctor through naked eye observation sick department can.

If the diseased part in the ear of the patient is at a deep position in the ear, such as the tympanic membrane or the middle ear, when the doctor is treating, the head end is put into the external auditory canal after the guiding optical fiber 141 and the illuminating optical fiber 142 are started, and the tail end is pushed to completely immerse into the ear canal. At this time, the doctor controls the sequence of the power supply to the plurality of micro-coils 13 to make the magnetofluid outer membrane 12 creep in the external auditory canal, and drives the body 11, the guiding optical fiber 141 and the illuminating optical fiber 142 to move in the external auditory canal. Until the endoscope 1 reaches the focus, the doctor stops the deformation of the magnetofluid outer film 12 by stopping the energization of the micro coil 13, and further stops the advancement of the endoscope 1. The doctor can clearly observe the focus condition in the ear, so that the doctor can make accurate diagnosis on the disease condition of the patient and is convenient for follow-up treatment. Meanwhile, even if the treatment experience of the doctor is insufficient, since the doctor does not need to hold the endoscope 1 by hand, the condition that the endoscope 1 damages the in-ear structure due to the over-tension of the doctor or the shaking of the hand and the like does not occur. After the doctor finishes the examination, the micro coils 13 are controlled to be electrified in sequence again, the electrifying sequence of the micro coils 13 is opposite to the electrifying sequence when the endoscope 1 enters the ear, and the peristalsis direction of the magnetofluid outer membrane 12 is opposite to the peristalsis direction when the magnetofluid outer membrane enters the ear. At this time, the magnetofluid outer film 12 drives the endoscope 1 to gradually move out of the external auditory canal, and the doctor can directly take out the endoscope 1. In the inspection process, the doctor only needs to put the endoscope 1 into the external auditory canal or take out the endoscope 1 from the external auditory canal, when the endoscope 1 stretches into the tympanic membrane or the middle ear, the doctor does not need to hold the endoscope 1 by hand, and the damage to the inside of the ear of the patient caused by misoperation of the doctor is greatly reduced. The wriggling of magnetic fluid adventitia 12 in the ear is realized through controlling the circular telegram in proper order of micro coil 13 to drive the gos forward of body 11, further guaranteed patient's safety, and when endoscope 1 reached focus department, owing to need not the handheld endoscope 1 of doctor, what guide's optic fibre 141 can be more stable shoots the focus, make the focus that sees that the doctor can be more clear, and make accurate analysis, improve diagnostic efficiency and diagnostic accuracy.

Optionally, along the extending direction of the imaging pipe 14, a plurality of micro coils 13 are arranged at intervals on two opposite side surfaces of the imaging pipe 14. The axial section of the body 11 is oval, and the radial section of the body 11 is round, so the magnetofluid outer membrane 12 is easy to roll in the auditory canal, the magnetic field generated by the miniature coil 13 arranged on one side is weak and not uniform enough, and the endoscope 1 is easy to shift when moving in the auditory canal, so that the auditory canal of a patient is damaged. Therefore, the upper and lower groups of micro coils 13 which are arranged in axial symmetry by taking the imaging pipeline 14 as an axis, and the two oppositely arranged micro coils 13 are electrified simultaneously, so that the stability of the magnetofluid outer membrane 12 in the creeping process is ensured, and the endoscope 1 can move stably in the auditory canal.

Optionally, the magnetic fluid outer membrane 12 comprises a peristaltic outer membrane 121 and a magnetic fluid layer 122, the peristaltic outer membrane 121 is fixed on the outer periphery side of the body 11, and the magnetic fluid layer 122 is filled between the peristaltic outer membrane 121 and the body 11. The peristalsis outer membrane 121 is a coating layer structure made of a flexible material, the magnetofluid layer 122 is filled between the peristalsis outer membrane 121 and the body 11, and the magnetofluid layer 122 deforms under the action of a magnetic field generated by the electrified micro-coil 13 and pushes the peristalsis outer membrane 121 to deform. The micro-coils 13 at different positions are sequentially electrified, so that the peristaltic outer membrane 121 is sequentially deformed in a wave shape along the axial direction of the body 11, and the peristaltic outer membrane 121 generates position change of the endoscope 1 in the auditory canal through interaction force between the peristaltic outer membrane 121 and the auditory canal.

Optionally, the head end and the tail end are both ellipsoidal, and the magnetic fluid outer membrane 12 is arranged to avoid the head end and the tail end. Because structures such as eardrums, middle ears or ossicles in ears of a human body are fragile and spread over tiny and fragile blood vessels, if the end part of the endoscope 1 is rectangular or triangular and has a corner structure, the structures in the ears are easily scratched, and bleeding and even damage to the eardrums are caused. If the ear canal is lacerated to cause bleeding, not only secondary damage can be caused to the patient, but also the observation effect of the endoscope 1 can be greatly influenced due to the bleeding. When the diagnosis is finished and the endoscope 1 is withdrawn from the auditory canal, the tail end of the body 11 firstly penetrates out of the auditory canal, and the tail end is also set to be ellipsoidal in order to avoid the damage of the tail end to the inner wall of the auditory canal. The head end and the tail end of the endoscope 1 are both arranged to be ellipsoidal, so that the damage of the head end to the inner wall of the auditory canal can be greatly avoided, and the patient is further protected.

Wherein, body 11 includes head end, middle section and tail end, and the head end is as the shooting position of guide's optic fibre 141 and the illumination position of illumination optic fibre 142, if the cladding has magnetic fluid adventitia 12, can influence and shoot and illuminating effect. And the tail end is provided with a wire for supplying power and transmitting signals for the satellite ticket counting, the guiding optical fiber 141 and the lighting optical fiber 142, and the ellipsoidal structures at the head end and the tail end cannot provide auxiliary effect for the displacement of the endoscope 1 even if the magnetofluid outer film 12 is arranged and deformed under the action of the electrified micro coil 13 on the magnetofluid outer film 12.

Alternatively, the body 11 has an elliptical cross-section in the axial direction, and the body 11 has a circular cross-section in the radial direction. When the body 11 is driven by the magnetic fluid outer film 12 and moves in the ear, the magnetic fluid outer film 12 can move with the inner wall of the ear canal to form a foundation, although the magnetic fluid outer film 12 is flexible, in order to further protect the inner wall of the ear canal, the section of the body 11 along the circumferential direction is set to be oval, and the section of the body 11 along the radial direction is set to be round, so that the magnetic fluid outer film 12 coated outside can be cylindrical, and the ear canal is prevented from being damaged by the magnetic fluid outer film 12.

In a second aspect, the present embodiment provides a detection apparatus, which includes a controller 2, a display, and the endoscope 1 described in any one of the above, wherein the controller 2 is configured to control the opening and closing of the micro-coil 13 and the imaging conduit 14. The controller 2 controls the micro coils 13 at different positions to be sequentially electrified, the magnetic fluid outer film 12 can be deformed when being positioned in the magnetic field, and the micro coils 13 at different positions are controlled to be sequentially electrified, so that the magnetic fluid outer film 12 can generate a peristaltic effect, and the body 11 is driven to move in the auditory canal. The controller 2 controls the start of the guiding optical fiber 141 and the lighting optical fiber 142, so that the condition inside the auditory canal can be shot clearly, and a doctor can clearly observe the condition inside the auditory canal through an external display.

Optionally, the controller 2 includes a control box 21 and a processing module, the processing module is disposed in the control box 21, the imaging tube 14 penetrates through the inner cavity along the length direction of the body 11, and the processing module is electrically connected to the tail end of the imaging tube 14. The control box 21 is provided with control buttons which are electrically connected with the processing module, and different devices can be started through different control buttons. For example, before the endoscope 1 is placed in the ear canal during use, the guiding optical fiber 141 and the illuminating optical fiber 142 can be activated by corresponding buttons on the control box 21; after the endoscope 1 is placed into the auditory canal, the micro-coils 13 at different positions can be controlled to be sequentially electrified through corresponding buttons on the control box 21, so that the magnetofluid outer membrane 12 generates a peristaltic effect, and the body 11 is driven to move deep in the auditory canal. Meanwhile, the picture shot by the guide optical fiber 141 is transmitted to the processing module, and the control box 21 can be externally connected with a display, so that the effect of realizing the picture in the auditory canal on the display is realized, and the observation by a doctor is facilitated.

Optionally, an interface 22 is disposed on the control box 21, the interface 22 is electrically connected to the processing module, and the display is electrically connected to the interface 22. The display is connected with the processing module through a data line, so that the stability of image transmission of the guide optical fiber 141 is ensured, a doctor can observe a focus more accurately, and the most accurate judgment is made.

Optionally, a bluetooth module is further disposed in the control box 21, and the bluetooth module is in signal connection with the processing module. In order to facilitate the use, another bluetooth module can be provided in the display, utilize two bluetooth modules, need not the data line, can show the picture that guide optical fiber 141 shot on the display. If this detecting instrument uses in narrower and small space, reduces external pencil, can effectually avoid medical personnel or the touching of disease, can avoid the pencil to trip the damage that the personnel caused.

Specifically, when examining the eustachian tube, the physician puts the endoscope 1 into the nasal cavity or oral cavity of the patient by turning on the corresponding buttons on the control box 21 to activate the guiding optical fiber 141 and the illuminating optical fiber 142. At this time, the picture taken by the guiding optical fiber 141 is transmitted to the display through the bluetooth module, and the doctor can clearly observe the position of the endoscope 1 in the human body by observing the content on the display. The magnetofluid outer membrane 12 is deformed and creeps by sequentially electrifying the plurality of micro coils 13, so that the endoscope 1 moves in the oral cavity or the nasal cavity until the endoscope 1 reaches the focus of the eustachian tube, the power supply to the micro coils 13 is stopped at the moment, the endoscope 1 stops moving, the illuminating optical fiber 142 illuminates the focus, the shooting effect of the guiding optical fiber 141 is improved, and a doctor can observe the specific condition of the focus of the eustachian tube through the display. When a doctor needs to change the angle to observe a focus, the micro coil 13 at different positions is powered, so that the magnetofluid outer film 12 wriggles to adjust the position of the endoscope 1 until the guiding optical fiber 141 can shoot the content required to be observed by the doctor.
