It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
In a first aspect, as shown in fig. 1, an embodiment of the present application provides an endoscope, including:
the body 11 is of a hollow structure and is provided with an inner cavity; the body 11 is configured as a main body of the endoscope 1, and can be inserted into a position such as a eustachian tube, an external auditory meatus, a tympanic membrane, or a middle ear.
A photosensitive outer film 12, wherein the photosensitive outer film 12 is coated on the outer peripheral side of the body 11; the photosensitive outer film 12 is made of a photo-deformable material, and deforms when the photosensitive outer film 12 is stimulated by light. Taking the inspection of the endoscope 1 applied to the inside of the ear as an example, by illuminating different positions of the photosensitive outer membrane 12, the photosensitive outer membrane 12 can generate peristaltic effect, and then the body 11 is driven to generate displacement in the ear. Since the photosensitive outer film 12 is a flexible material, the photosensitive outer film 12 can also protect the inside of the ear from damage when peristaltic within the ear. And because the deformation of the photosensitive outer membrane 12 is controlled by controlling the illumination position, the peristaltic movement of the photosensitive outer membrane 12 drives the body 11 to move in the ear, so that the damage to the auditory canal or the tympanic membrane caused by misoperation when a doctor needs to operate the traditional endoscope 1 by hand is avoided, and the safety of a patient when the endoscope 1 is used is further protected.
A light emitting array 13, wherein the light emitting array 13 is arranged between the photosensitive outer film 12 and the body 11, the illumination direction of the light emitting array 13 faces the photosensitive outer film 12, and the light emitting array 13 can be lighted in a partitioning manner; the light emitting array 13 is located at the outer peripheral side of the body 11, and the light emitting array 13 is located between the photosensitive outer film 12 and the body 11, and the light emitting of different areas of the light emitting array 13 is controlled to deform the photosensitive outer film 12 in areas. For example, the light emitting arrays 13 are sequentially started along the axis direction of the body 11, so that the photosensitive outer film 12 can creep towards a specified direction, and the body 11 is driven to reach a specified position.
An imaging tube 14, the imaging tube 14 being fixed in the inner cavity along the axial direction of the body 11, the imaging tube 14 being configured to have illumination and photographing functions; when the endoscope 1 of the present application is used, the environment in the ear is dark and narrow, so that the imaging tube 14 is required to illuminate the ear to enable shooting and recording. After the imaging tube 14 illuminates the ear, the image is taken and recorded, the taken image is transmitted to the display, and the doctor can diagnose or treat the disease of the patient through the real image on the display. The doctor can acquire the image in the ear of the patient without manually operating the endoscope 1, thereby reducing the situation of secondary injury to the ear caused by misoperation of the doctor.
When each area of the light emitting array 13 emits light sequentially, the light emitting area of the photosensitive outer film 12 corresponding to the light emitting array 13 is peristaltic sequentially. Specifically, during the treatment, the doctor only needs to put the endoscope 1 in the application into the ear of the patient, and starts the imaging tube 14, and at this time, the image in the ear can be displayed on the display. The direction of the movement of the endoscope 1 in the ear is controlled by the controller 2, for example, the endoscope 1 needs to advance, the light emitting arrays 13 are sequentially lightened along the first direction by controlling the controller 2, and the corresponding photosensitive outer membranes 12 also creep along the first direction, so that the body 11 and the imaging pipeline 14 are driven to advance in the ear. If the endoscope 1 is required to retreat in the ear, the light emitting arrays 13 are sequentially lightened along the second direction by controlling the controller 2, and the corresponding photosensitive outer membranes 12 also 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, which is an independent organ, is an anatomic passageway that communicates with the nasal cavity, pharyngeal cavity and middle ear cavity, and has two openings, one opening to the middle ear drum and the other opening to the nasopharynx. The eustachian tube plays an important role in human body, such as balancing the air pressure of the middle ear cavity and the outside air, draining secretion or effusion of 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, one part is a bone part, which is close to the middle ear, the periphery of the tube cavity is a bony structure, and the tube cavity of the part is non-expandable; the other part is a cartilage part, the part is close to the nasopharynx part, soft tissue structures such as cartilage, fat and the like are arranged around the lumen, the lumen of the eustachian tube presents a fold shape, and the lumen has certain expansibility. The mucous membrane covered on the surface of the eustachian tube is similar to the respiratory tract system and is also a ciliated mucous membrane system, and the eustachian tube is in a closed state in a normal state, but is surrounded by numerous osseous structures, large blood vessels and muscular structures due to the eustachian tube being positioned at the skull base, so that the eustachian tube is deep in structure, and the eustachian tube part is difficult to directly inspect or sample by a conventional means due to the anatomical structures.
Normally, the eustachian tube is in a closed state, and can be blocked or opened abnormally in pathology. The eustachian tube of children is shorter, wider and more horizontal, and easy retrograde infection leads to otitis media, and eustachian tube lumen cilia mucosa covers in eustachian tube lumen fold, and it is different from other respiratory cilia mucosa's unique place. The lumen cavity is narrow, and is mainly in a closed state in a physiological state, and the traditional examination of the function of the eustachian tube mainly focuses on whether the lumen is smooth or not, but examination equipment is lacked in the prior art to realize the examination and pathological research of the eustachian tube.
The endoscope 1 in this application embodiment then can be fine inspect the eustachian tube, and endoscope 1 can get into in the human body through oral cavity or nasal cavity, starts the luminous array 13 and makes photosensitive adventitia 12 produce deformation peristaltic motion, and then makes endoscope 1 remove in oral cavity or nasal cavity, reaches eustachian tube department until the endoscope, makes 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 tube 14 includes a guide optical fiber 141 and an illumination optical fiber 142, the body 11 has a head end and a tail end, the guide optical fiber 141 and the illumination optical fiber 142 extend from the tail end to the head end, and the shooting direction of the guide optical fiber 141 and the illumination direction of the illumination optical 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 placed in the auditory canal, and the endoscope 1 is placed in the auditory canal in sequence 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 inside of the ear canal through the illumination fiber 142, and shoot and transmit the view in the ear canal through the guide fiber 141.
If the illness in the ear of the patient is outside the external auditory canal, the examination can be realized without putting the endoscope 1 into the ear canal entirely, at this time, the doctor can choose to independently turn on the illumination optical fiber 142 to improve the visibility of the external auditory canal, and the doctor can observe the illness through naked eyes.
If the patient is in a position deeper in the ear, such as the tympanic membrane or middle ear, the doctor activates the guide fiber 141 and illumination fiber 142 to place the head end in the external auditory canal and pushes the tail end so that the tail end is completely immersed in the ear canal. At this time, the doctor makes the photosensitive outer film 12 creep in the external auditory meatus by controlling the light emitting sequence of the light emitting array 13, and drives the body 11, the guide optical fiber 141 and the illumination optical fiber 142 to move in the external auditory meatus. Until the endoscope 1 reaches the focus, the doctor stops the deformation of the photosensitive adventitia 12 by turning off the light emitting array 13, and further stops the advancement of the endoscope 1. At the moment, doctors can clearly observe the focus condition in the ears, thereby being convenient for the doctors to accurately diagnose the illness state of patients and facilitating the subsequent treatment. Meanwhile, even if the treatment experience of the doctor is insufficient, the doctor does not need to hold the endoscope 1, so that the situation that the endoscope 1 damages the in-ear structure due to the situation that the doctor is too stressed or hands shake, etc. does not occur. When the doctor finishes the examination, the light emitting array 13 is controlled to be started again, at this time, the light emitting sequence of the light emitting array 13 is opposite to the light emitting sequence of the endoscope 1 before entering the ear, and the peristaltic direction of the photosensitive outer membrane 12 is opposite to the peristaltic direction before entering the ear. At this time, the photosensitive adventitia 12 drives the endoscope 1 to gradually move out of the external auditory meatus, and the doctor takes out the endoscope 1 directly. In the examination process, a doctor only needs to put the endoscope 1 into or take out from the external auditory meatus, and when the endoscope 1 stretches into the tympanic membrane or the middle ear, the doctor does not need to hold the endoscope 1, so that the damage to the ear of a patient caused by misoperation of the doctor is greatly reduced. The peristaltic movement of the photosensitive outer membrane 12 in the ear is realized by controlling the light emitting array 13, so that the body 11 is driven to advance, the safety of a patient is further ensured, and when the endoscope 1 reaches a focus, a doctor is not required to hold the endoscope 1, the guide optical fiber 141 can shoot the focus more stably, so that the doctor can see the focus more clearly, and make accurate analysis, and the diagnosis efficiency and the diagnosis accuracy are improved.
Optionally, a plurality of grooves 121 are formed on the photosensitive outer film 12 at intervals along the length direction of the body 11. Since the photosensitive outer film 12 deforms during the peristaltic process, the grooves 121 are formed in the photosensitive outer film 12 at intervals, so that the grooves 121 can provide a larger movement allowance for the photosensitive outer film 12 during the peristaltic process of the photosensitive outer film 12, and the deformation amount of the photosensitive outer film 12 is improved. Meanwhile, if the grooves 121 are not formed in the photosensitive outer film 12, the photosensitive outer film 12 is extruded after a long service time, and damage and the like are easy to occur, and the occurrence of the situation can be effectively avoided by forming the grooves 121 in the photosensitive outer film 12.
Optionally, the opening direction of the groove 121 is perpendicular to the axis of the body 11, for example, the body 11 is cylindrical, the body 11 is horizontally placed, and the axis of the body 11 is horizontal. At this time, the photosensitive outer film 12 is coated on the peripheral side of the body 11, and the groove 121 is opened on the photosensitive outer film 12 along the circumferential direction of the body 11. When the photosensitive outer membrane 12 generates peristaltic motion, the grooves 121 can provide deformation allowance for the photosensitive outer membrane 12 to the greatest extent, and the displacement speed of the endoscope 1 in the ear is improved.
Optionally, the head end and the tail end are ellipsoidal, and the photosensitive outer film 12 is disposed opposite to the head end and the tail end. Because structures such as tympanic membrane, middle ear or ossicles in human ears are fragile and spread over tiny and fragile blood vessels, if the end part of the endoscope 1 is rectangular or triangular or other structures with edges and corners, the structures in the ears are easily scratched, and bleeding and even damage of the tympanic membrane are dangerous. If the auditory canal is scratched to cause bleeding, secondary injury can be caused to a patient, and meanwhile, the observation effect of the endoscope 1 can be greatly influenced due to the bleeding. When the endoscope 1 is withdrawn from the ear canal after diagnosis, the tail end of the body 11 first passes through the ear canal, and the tail end is also configured as an ellipsoid shape in order to avoid damage to the inner wall of the ear canal by the tail end. The head end and the tail end of the endoscope 1 are both arranged to be ellipsoids, so that the head end can be prevented from damaging the inner wall of the auditory canal greatly, and patients can be further protected.
The body 11 includes a head end, a middle section and a tail end, wherein the head end is used as a shooting position of the guide optical fiber 141 and an illumination position of the illumination optical fiber 142, and if the photosensitive outer film 12 is coated, shooting and illumination effects are affected. The tail end is provided with a wire for supplying power to the light emitting array 13, the guide optical fiber 141 and the illumination optical fiber 142 and transmitting signals, and the ellipsoidal structure of the head end and the tail end can not provide auxiliary effect for the displacement of the endoscope 1 even if the photosensitive outer film 12 is arranged, after the photosensitive outer film 12 is deformed by illumination.
Alternatively, the cross section of the body 11 along the axial direction is elliptical, and the cross section of the body 11 along the radial direction is circular. When the body 11 is driven by the photosensitive outer film 12 to displace in the ear, the photosensitive outer film 12 can be used for carrying out foundation with the inner wall of the auditory canal, and although the photosensitive outer film 12 has flexibility, in order to further protect the inner wall of the auditory canal, the circumferential section of the body 11 is set to be elliptical, and the radial section of the body 11 is set to be circular, so that the photosensitive outer film 12 coated outside can be cylindrical, and damage to the auditory canal caused by the photosensitive outer film 12 is avoided.
In a second aspect, as shown in fig. 1, an embodiment of the present application provides a detection apparatus, including a controller 2, a display, and the endoscope 1 described in any of the foregoing, where the controller 2 is configured to control opening and closing of the light emitting array 13 and the imaging tube 14. The controller 2 controls the starting of the light emitting array 13, the photosensitive outer membrane 12 deforms after being illuminated, and the regional starting of the light emitting array 13 is controlled, so that the peristaltic effect of the photosensitive outer membrane 12 is realized, and the body 11 is driven to move in the auditory canal. The controller 2 controls the starting of the guide optical fiber 141 and the illumination optical fiber 142, thereby facilitating the clear shooting of the situation inside the auditory canal, and enabling a doctor to clearly observe the situation 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 endoscope 1 has a head end and a tail end, the imaging tube 14 passes from the tail end to the head end, and the processing module is electrically connected with the tail end of the imaging tube 14. The control box 21 is provided with control buttons, which are electrically connected to the processing module, by means of which different devices can be activated. For example, during use, before endoscope 1 is placed in the ear canal, guide fiber 141 and illumination fiber 142 may be activated by corresponding buttons on control box 21; after the endoscope 1 is placed into the auditory canal, the luminous arrays 13 can be started through corresponding buttons on the control box 21, so that the luminous arrays 13 are sequentially lightened, the photosensitive outer membrane 12 is enabled to generate peristaltic effect, and the body 11 is driven to move to the depth of the auditory canal. Meanwhile, the pictures shot by the guide optical fiber 141 are transmitted to the processing module, and a display can be externally connected on the control box 21, so that the effect of realizing pictures in the auditory canal on the display is realized, and the observation of doctors is facilitated.
Optionally, an interface 22 is provided 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 and the processing module are connected through a data line, so that the stability of image transmission of the guide optical fiber 141 is guaranteed, 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 may be disposed in the display, and the two bluetooth modules are utilized to implement the image shot by the guiding optical fiber 141 on the display without a data line. If the detecting instrument is used in a relatively narrow space, the external wire harness is reduced, the touch of medical staff or patients can be effectively avoided, and the damage caused by wire harness tripping staff can be avoided.
Specifically, during the examination of the eustachian tube, the doctor places the endoscope 1 in the nasal or oral cavity of the patient by activating the guide fiber 141 and the illumination fiber 142 by activating the corresponding buttons on the control box 21. The picture shot by the guide 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 at this time by observing the content on the display. The light-emitting array 13 is started to enable the photosensitive adventitia 12 to creep in the oral cavity or the nasal cavity until the endoscope 1 reaches the focus of the eustachian tube, at the moment, the light-emitting array 13 is closed to stop the movement of the endoscope 1, the focus is illuminated by the illumination optical fiber 142, the shooting effect of the guide optical fiber 141 is improved, and a doctor can observe specific conditions of the focus of the eustachian tube through the display. When the doctor needs to change the angle to observe the focus, the light emitting array 13 is started again, so that the photosensitive adventitia 12 is peristaltic to adjust the position of the endoscope 1 until the guide optical fiber 141 can shoot the content required to be observed by the doctor. Through the detecting instrument of the embodiment, the eustachian tube can be comprehensively and accurately observed, the accuracy of judging the focus of the eustachian tube by doctors is improved, and the treatment efficiency is improved.
Wherein, the processing module of the controller 2 is connected with the light emitting array 13, the guide optical fiber 141 and the illumination light 142 through wires, one of the wires penetrates into the inner cavity through the tail end of the shell of the body 11, the position on the body 11 corresponding to the position provided with the light emitting array 13 is provided with a threading hole, and the wire is electrically connected with the light emitting array 13 through the threading hole, thereby realizing the control of the processing module on the light emitting array 13. Meanwhile, when the endoscope 1 needs to be taken out from the human body, the endoscope 1 can be taken out by pulling the wire when the endoscope 1 reaches a relatively wide position, so that the treatment process is quickened.
