Description

Inspection mirror and inspection device

Technical Field

The present disclosure relates generally to the field of medical devices, and more particularly to an inspection scope and inspection device.

Background

In clinic, endoscopes are commonly used to examine the lesion position and condition of the internal cavity of the human body. The existing endoscopes are classified into otorhinolaryngoscopes, oral endoscopes, dental endoscopes, neuroscopes, urocystoscopes, resectoscopes, laparoscopes, arthroscopes, nasosinusiscopes, laryngoscopes or colposcopes. When gynecological diseases are to be examined and diagnosed, hospitals typically use colposcopes for examination, screening and diagnosis.

Colposcopy, also commonly referred to as a vaginal endoscope or colposcope, is an instrument used to clinically see the presence or absence of lesions in the vulvar tissue, vagina, cervix. The colposcopy is to enlarge and display the image by the display device under the irradiation of the self-contained strong light source, thereby observing the tiny lesions of the vulva, the vagina and the cervix which are invisible to the naked eye, and further enabling doctors to judge the symptoms more easily and accurately; in addition, acetic acid can be coated on the cervical part to observe whether a white acetic acid epithelium exists or not, whether the white acetic acid epithelium boundary is clear or thick or not, and the pathological change part is analyzed by observing the white acetic acid epithelium boundary and the thickness; in addition, biopsy sampling of cervical and vaginal tissue may also be performed under colposcopy.

However, the prior colposcope is generally large in size and high in price, so that the use scene of the colposcope is limited to a certain extent, and the portable requirement cannot be met under the conditions of encouraging doctors to carry out multi-point practice and encouraging hospitals to provide rural diagnosis and treatment services. In addition, the existing colposcope has single lamplight color, and can not meet the requirement of rapid diagnosis of various medical detection means at the present stage.

Detailed Description

The inspection scope to which the present disclosure relates may be understood more readily by reference to the following detailed description of certain embodiments and the examples included therein, and to the accompanying drawings and their preceding and following description.

In the following description, the same members are denoted by the same reference numerals, and overlapping description thereof is omitted. In addition, the drawings are schematic, and the ratio of the sizes of the components to each other, the shapes of the components, and the like may be different from actual ones.

It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present disclosure which will be limited only by the appended claims.

While particular examples of the present disclosure have been shown and described, it will be obvious to those skilled in the art that, based upon the teachings of this disclosure, changes and modifications may be made without departing from this disclosure and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this disclosure. Those skilled in the art will appreciate that, in general, terms used in this disclosure are generally intended to be "open" terms (e.g., the term "comprising" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least").

A first aspect of the present disclosure relates to an inspection scope that may be used to illuminate and image a narrow darkened channel, thereby facilitating operator viewing of the condition within the narrow darkened channel.

The present disclosure relates to an inspection scope that may be used for gynecological examinations, in particular, vaginal examinations. In this embodiment, the scope may be used in conjunction with a dilator. According to the present disclosure, an inspection scope can be provided that facilitates illumination and imaging within the vagina.

In this embodiment, the scope may also be referred to as a colposcope, colposcope device, or colposcope illumination and photographing device, etc. In this embodiment, the operator may be a doctor, and the examination mirror may be used in an examination department of a hospital or may be carried by the operator and used outside.

In this embodiment, the scope may be used to illuminate and capture the vaginal cervix and to transmit the captured pictures and video for presentation on a display and storage.

A second aspect of the present disclosure relates to an inspection apparatus comprising the inspection scope of the first aspect of the present disclosure.

Hereinafter, an inspection scope according to the present embodiment will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view showing an inspection mirror 1 according to an example of the present disclosure. Fig. 2 is a perspective view showing another view angle of the inspection mirror 1 according to the example of the present disclosure.

Fig. 3 is an exploded schematic view showing an inspection mirror 1 according to an example of the present disclosure. Fig. 4 is an exploded schematic diagram showing a camera module and an illumination module to which examples of the present disclosure relate. Fig. 5 is a front view showing the image pickup module and the illumination module according to the example of the present disclosure.

Referring to fig. 1 and 2, in some examples, the inspection scope 1 may include a housing 10, and the housing 10 may have a cavity. In some examples, the housing 10 may be elongated. Thereby making it easier for the operator to hold and operate the inspection scope 1 with one hand, while enabling the inspection scope 1 to have better portability. In some examples, the housing 10 may be cylindrical, such as cylindrical, quadrangular, hexagonal.

In some examples, the inspection scope 1 may further include a control module, a camera module, and an illumination module, which may be disposed in the chamber, i.e., the control module, the camera module, and the illumination module may be housed inside the housing 10.

In some examples, the control module may be electrically connected with the camera module, the illumination module, respectively. In other words, the control module may control the camera module and the illumination module by means of the circuit signals, respectively.

In some examples, the illumination module may be used to provide an illumination source for the camera module. For example, when the camera module performs shooting and video recording at the vaginal cervix, the illumination module may provide illumination light so that the camera module may perform normal shooting operations.

In some examples, the lighting module may emit light of multiple colors. In particular, the lighting module may switch back and forth between light of multiple colors. For example, when the photographing operation of the photographing module requires white light, the illumination module may emit white light; when blue light is needed for shooting operation of the camera module, the illumination module can switch white light into blue light.

In some examples, referring to fig. 1, the housing 10 may have a window portion 110, and the window portion 110 may be optically transmissive. In some examples, the window portion 110 may be located within a field of view of the camera module, and the window portion 110 may provide a light path for the illumination module. In other words, since the image pickup module is provided inside the housing 10, the image pickup module can acquire an image of the outside of the inspection scope 1 through the window portion 110 when the image pickup module performs a photographing operation; similarly, the light emitted by the illumination module can penetrate the window portion 110 to irradiate the vaginal cervix, and reflect back to be captured by the image capturing module, so that the image capturing module obtains a clear image.

In some examples, the control module may control the camera module to take images through an electrical signal, and may also control the illumination module to change between lights of multiple colors through an electrical signal.

In the present embodiment, by providing the control module, the imaging module, and the illumination module inside the housing 10, the components inside the inspection scope 1 can be better protected; in addition, the window part 110 arranged on the shell 10 can provide a window for shooting visual field for the camera module and a light path for the illumination module, and meanwhile, the window part 110 can also protect the camera module and the illumination module; the control module controls the camera shooting module to shoot and controls the illumination module to illuminate, and can control the illumination module to change among the lights with various colors, so that the colors of the lights can be switched according to the actual inspection requirement. As the pathological change tissue of the human body is greatly distinguished from normal tissue under the irradiation of light with different colors after being treated, the pathological change position of the human body can be found by an operator more quickly through the light with different colors, thereby improving the diagnosis efficiency and accuracy of the operator.

In some examples, the housing 10 may include a first housing component 11 and a second housing component 12, and the first housing component 11 and the second housing component 12 may be detachably connected to form a chamber of the housing 10. In this case, by providing the first housing component 11 and the second housing component 12 that are detachable, the first housing component 11 and the second housing component 12 can be conveniently assembled in the cavity of the housing before the assembly, and the first housing component 11 and the second housing component 12 are combined after the assembly is completed so that each component is better protected in the cavity of the housing 10.

In some examples, the window portion 110 may be located near an end of the first housing component 11 (see fig. 1). This reduces the influence on the photographing operation caused by holding the inspection scope 1.

In some examples, the junction of the first housing assembly 11 and the second housing assembly 12 may be provided with a seal 101 (see fig. 3). Therefore, the inspection mirror 1 has good sealing performance after the first shell component 11 and the second shell component 12 are combined, so that the probability of liquid penetrating into the inspection mirror 1 is reduced, and each component in the inspection mirror 1 can be better protected. In some examples, the seal 101 may be a rubber gasket that conforms to the shape of the junction of the first housing component 11 and the second housing component 12.

In some examples, the lighting module may include an illumination lamp 420 (see fig. 4 and 5). The illumination lamp 420 may be used to provide illumination light for the camera module. In some examples, the number of illumination lamps 420 may be multiple. For example, as shown in fig. 5, the illumination lamp 420 may include an illumination lamp 420a, an illumination lamp 420b, an illumination lamp 420c, and an illumination lamp 420d.

In some examples, each illumination lamp 420 may emit a different color of light. For example, when the operator needs white light for illumination, the illumination lamp 420a may be controlled to emit white light, and so on, and the other illumination lamps 420b may also be controlled by the operator to emit light of other colors. In some examples, multiple illumination lamps 420 may also collectively emit light of the same color to increase the intensity of the illumination light.

In some examples, a plurality of illumination lamps 420 may be arranged around the camera module. In this case, the illumination lamp 420 is arranged around the camera module, so that the light emitted by the illumination lamp 420 is consistent with the shooting direction of the camera module, and balanced illumination light is provided for shooting by the camera module, so that the camera module can acquire images or videos with higher quality.

In some examples, the light of multiple colors emitted by the lighting module may include white light, blue light, and green light. In this case, the illumination module emits white light to provide normal illumination for the operator, and the illumination module emits blue light and green light to improve the diagnosis efficiency of the operator.

In some examples, the illumination module may emit white light that may be used to provide normal illumination to the camera module, and the white light does not affect the color of cervical tissue. Therefore, the observation by operators can be facilitated.

In some examples, the lighting module may emit blue light. When gynecological examination is carried out, the examination is usually carried out after acetic acid is coated on the cervix, and the diseased tissue in the human body can be whitened after acetic acid is coated, and the whitened tissue is more obvious under the illumination of blue light than under the illumination of white light and is obviously compared with normal tissue. Therefore, the blue light emitted by the illumination module can help an operator diagnose the lesion position, and the diagnosis efficiency and the diagnosis accuracy of the operator can be improved.

In some examples, the lighting module may emit green light. In general, capillaries on human tissue appear more pronounced under illumination with green light. Therefore, the illumination module emits green light to carry out filtering inspection to confirm whether the abnormal blood vessel exists in the patient, so that diagnosis of the lesion position by an operator can be facilitated, and the diagnosis efficiency and the diagnosis accuracy of the operator can be improved.

It should be appreciated that the color of the light emitted by the illumination module is not limited to just a few of the above examples, but that the illumination module may also emit light of other colors depending on the actual use of the examination mirror 1.

In some examples, referring to fig. 3, 4, and 5, the camera module may include a camera 310 and a lens hood 340, the camera 310 for image capture, the lens hood 340 for reducing the effect of light on the camera 310.

In some examples, lens hood 340 may be disposed around camera 310. In this case, the lens hood 340 disposed around the camera 310 can reduce the influence of the bright light emitted from the illumination lamp 420 on the photographing of the camera 310, and thus can reduce the influence of the illumination lamp 420 on the imaging quality of the camera module.

In some examples, referring to fig. 4, an upper end 341 of the lens hood 340 may abut the window portion 110. In this case, the light emitted from the illumination lamp 420 can be reduced, and reflected from the window portion 110 into the field of view of the camera 310, whereby the imaging quality of the camera module can be further improved.

In some examples, the material of lens hood 340 may be a black opaque material. Thus, the light emitted from the illumination lamp 420 can be well blocked.

In some examples, the camera module may further include a lens cover 320 and a bracket 330 (see fig. 3) for securing the camera 310 to the circuit board 210, wherein the bracket 330 may be in electrical connection with the circuit board 210. In some examples, the illumination lamp 420 may be secured to the bracket 330 by a lamp plate 410.

In some examples, the control module may include an MCU (i.e., a single-chip microcomputer or a micro-control unit). The MCU is configured to receive an operation signal of the operation module 220, and send a control instruction to the camera module and the illumination module.

In some examples, the control module may include a circuit board 210 (see fig. 3). The circuit board 210 may also be referred to as a circuit board or PCB board, and the circuit board 210 is used to provide conductive traces for the components within the inspection scope 1. In other words, each component in the inspection mirror 1 can be electrically connected to the circuit board 210.

Fig. 6A is a front view showing an inspection mirror 1 according to an example of the present disclosure. Fig. 6B is a side view showing the inspection mirror 1 according to the example of the present disclosure. Fig. 6C is a rear view showing the inspection mirror 1 according to the example of the present disclosure.

In some examples, the inspection scope 1 may further include an operation module 220 disposed to the housing 10. The operation module 220 may be connected with the control module. Thus, the operation module 220 enables an operator to send an operation instruction to the control module, thereby controlling the imaging module and the illumination module.

In some examples, the manipulator module 220 may be disposed on a side of the housing 10 opposite the window portion 110. Thus, when the operator holds the inspection scope 1 for inspection, the operation module 220 can be just in an area that can be operated by the thumb of the operator, whereby the convenience of operating the operation module 220 can be improved.

In some examples, the operation module 220 may include a plurality of keys disposed on a surface of the housing 10. In other examples, the operation module 220 may also be a touch screen or a joystick disposed on the surface of the housing 10. Thus, the operating module 220 can be conveniently manipulated in a variety of operating modes to achieve functional control of the inspection scope 1.

In some examples, the operation module 220 may be electrically connected to the circuit board 210, so as to control the image capturing module to capture an image and control the illumination module to illuminate.

Hereinafter, taking an example in which the operation module 220 includes a plurality of keys, a process in which the operation module 220 controls the inspection mirror 1 to realize the inspection function will be described in detail.

In some examples, referring to fig. 3, the operation module 220 may include at least one key 221. The operation module 220 may include a key press 222. The key 221 may be disposed on a surface of the key pressing plate 222 adjacent to the second housing assembly 12, and the key pressing plate 222 may be electrically connected to the circuit board 210.

In some examples, an operator pressing button 221 may control the turning on and off of inspection scope 1 and the operation of the camera module and illumination module by pressing plate 222 to send a control signal to circuit 101.

In some examples, the number of keys 221 may be multiple, and each key 221 may represent a function.

In some examples, a key indicator light that can display a corresponding key function may be provided on at least one key 221. For example, as shown in fig. 6A, the plurality of keys 221 may include a first key 221a, a second key 221b, a third key 221c, a fourth key 221d, and a fifth key 221e. The first key 221a may be an on-off key, the second key 221b may be a shooting and video key, the third key 221c may be a focusing key, the fourth key 221d may be an illumination key, the fifth key 221e may be a light conversion key, etc., and the corresponding function may be implemented after the corresponding key 221 is pressed. For example, when the first key 221a is pressed, the key indicator on the first key 221a may be turned on, thereby representing that the inspection scope 1 is currently in a power-on operation state; similarly, when the fifth button 221e is pressed, a button indication lamp on the fifth button 221e may be turned on.

In some examples, the color of the light of the key indicator may match the color of the light emitted by the lighting module. Specifically, when the light emitted from the lighting module is blue, the light of the key indicator of the fifth key 221e may also be blue, and when the light emitted from the lighting module is changed, the light of the key indicator may also be changed accordingly. In this case, by observing whether the key indicator lights are on or the color of the light of the key indicator lights, the operation module 220 can interact with the current operation action, so that the operator can know the current operation state of the inspection mirror 1 more clearly, and the convenience and visibility of operating the inspection mirror 1 can be improved. In addition, the operator can conveniently check the position of the key 221, and the possibility of key errors is reduced.

In some examples, the positions of the different keys 221 may be swappable. This allows the positions of the different keys 221 to be set according to the usage habits of the operator.

In some examples, the housing 10 may have a key hole 121 (see fig. 3) therein.

In some examples, a plurality of keys 221 may be disposed on the key holes 121. The profile of the key 221 may be adapted to the profile of the key hole 121 to form a smooth and compact connection of the housing 10 with the key 221 at the key hole 121. In this case, the entire surface of the housing 10 of the inspection scope 1 can be made smoother, so that the assembly of the inspection scope 1 with other devices (e.g., a dilator) can be made more convenient, and the risk of the service life of the key 221 being reduced due to a greater friction during the assembly of the inspection scope 1 to the other devices can be reduced.

In some examples, a sealed connection may be made between key 221 and key hole 121. Thereby, it is possible to preferably prevent the entry of contaminants such as body fluid, germs, etc. into the inside of the inspection scope 1 through the gap between the key 221 and the key hole 121.

In some examples, the key hole 121 may be located in the second housing component 12, and the key 221 may be disposed on the second housing component 12 in such a manner as to be engaged with the key hole 121, i.e., the key 221 may be disposed on a side opposite to the window portion 110. In this case, when the operator holds the inspection scope 1 with one hand to perform inspection, the key 221 is located just in the area where the thumb of the operator can operate, and thus, the operator can conveniently press the key 221 with the thumb to perform the operation, thereby conforming to the ergonomics.

In some examples, the logo on key 221 may be generated using a groove dispensing process. This can reduce the problem of abrasion of the key 221 marks due to friction when the key 221 is used in combination with the expander 2.

In some examples, referring to fig. 3, the window portion 110 may include a light-transmitting sheet 111, and the light-transmitting sheet 111 may provide good light transmission to the window portion 110. In some examples, the light transmissive sheet 111 may form a better seal with the window 110. This can reduce the entry of contaminants into the inspection scope 1.

In some examples, the light transmissive sheet 111 may have a hydrophobic coating. Thus, the window 110 can have excellent water repellency. In some examples, the hydrophobic plating layer may be disposed on the side of the light-transmitting sheet 111 facing the outside.

In some examples, an antireflection film may be coated on the light-transmitting sheet 111. This can provide the window 110 with better light transmittance.

In some examples, the light transmissive sheet 111 may be a glass lens made of a glass lens material.

Fig. 8 is a side schematic view showing the dilator 2 according to the example of the present disclosure. Fig. 9 is a schematic diagram showing detachment of the scope 1 and the dilator 2 according to the example of the present disclosure.

The present disclosure also relates to an inspection device 100, which inspection device 100 may comprise the inspection mirror 1 described above.

In some examples, referring to fig. 7, the examination apparatus 100 may comprise a dilator 2 and an examination mirror 1. The scope 1 may be used in conjunction with a dilator 2, which dilator 2 may be a vaginal dilator. In this case, the tissue tract (e.g., vagina) of the human body can be well dilated by the dilator 2, thereby providing a field of view and space for photographing or examination by the examination mirror 1.

In some examples, dilator 2 may have a dilator assembly 201 and a grip 202, where dilator assembly 201 may be used to dilate and support the vagina and grip 202 may facilitate grasping and manipulation by an operator.

In some examples, referring to fig. 9, the expansion assembly 201 can include an upper leaf 201a and a lower leaf 201b, and the upper leaf 201a and the lower leaf 201b can expand to expand the vagina to form the examination channel 204. In some examples, the view and space may be provided for the inspection scope 1 to take or inspect through the inspection channel 204.

In some examples, lower leaf 201b may be connected with grip 202. In some examples, the lower leaf 201b may have a first preset angle α between it and the grip 202 (see fig. 8). The first preset angle α may be greater than 90 degrees and less than 120 degrees. For example, the first preset angle α may be 95 degrees, 100 degrees, 102 degrees, 110 degrees, or 117 degrees. In some examples, preferably, the first preset angle α between the lower leaf 201b and the grip 202 may be 102 degrees. In this case, after the operator grips the grip 202 in a natural form of one hand, the lower blade 201b and the arm can be made substantially in a straight line, and the natural form of the human hand can be relatively matched, whereby the convenience of the operator in operating the dilator 2 can be improved. In addition, when the operator holds and operates the expander 2 with one hand to expand the vagina, the first preset angle α can cause the hand to deviate in a direction away from the person under examination (for example, a patient), so that the contact between the hand of the person under examination and the person under examination can be preferably avoided.

In some examples, the grip 202 may have a receiving cavity, one end of which may have an opening 203 (see fig. 9). In some examples, the receiving cavity may be a sealed structure in other directions than the opening 203. In other words, the grip 202 is in communication with the outside only at the opening 203, and other positions may be in a sealed structure. In this case, when the inspection scope 1 is placed in the accommodation chamber of the grip portion 202, the contaminant flowing out from the inside of the vagina along the expansion member 201 is not likely to enter the accommodation chamber to contaminate the inspection scope 1.

In some examples, the inspection scope 1 may be disposed within the receiving cavity of the grip portion 202. Specifically, the inspection scope 1 can be placed into the accommodating cavity of the holding portion 202 through the opening 203, and is detachably clamped in the accommodating cavity of the holding portion 202. Thereby, the ease of assembly between the scope 1 and the expander 2 can be improved.

In practice, in order to improve the efficiency and accuracy of the operator's inspection, the dilator assembly 201 of the dilator 2 needs to be placed into the vagina to dilate the vagina, and in order to prevent cross-infection, the dilator 2 is generally not reusable, i.e. the dilator 2 is generally a disposable medical device. The inspection mirror 1 is reused as much as possible in view of cost. In view of this, the scope 1 and the dilator 2 of the present embodiment are designed to be detachably connected, the dilator 2 is a disposable medical device, and the scope 1 can be reused after necessary sterilization. In use, the inspection scope 1 and the dilator 2 are assembled together; after use, the inspection scope 1 is detached from the dilator 2, the dilator 2 can be discarded, and the inspection scope 1 can be sterilized for the next use.

In some examples, referring to fig. 8, the other end of the grip 202 remote from the opening 203 may have a viewing window 205, and the viewing window 205 may be provided with a light-transmitting plate. Thereby, the other end of the grip 202 away from the opening 203 can be made to form a sealed and light-transmitting end.

In some examples, the viewing window 205 may be aligned with the inspection channel 204, i.e., the viewing window 205 may be flared toward the inspection channel 204 formed by the upper leaf 201a and the lower leaf 201 b.

In some examples, when the inspection scope 1 is placed in the accommodating cavity of the holding portion 202, the window portion 110 of the inspection scope 1 may correspond to the observation window 205, that is, the window portion 110 may be attached to the observation window 205. In this case, the window portion 110 can be aligned with the inspection channel 204, and the inspection scope 1 can be made to photograph or inspect the vaginal cervix through the light-transmitting plate.

In some examples, the plane of the window 110 may be at an angle to the central axis L2 of the housing 10. In other words, referring to fig. 6B, a second preset angle β may be formed between the first axis L1, which is orthogonal to the plane in which the window portion 110 is located, and the central axis L2 of the housing 10.

In some examples, the second preset angle β may be the same as the first preset angle α. That is, the second preset angle β between the first axis L1 and the central axis L2 may be equal to the first preset angle α between the lower leaf 201b and the grip portion 202. In this case, when the inspection scope 1 is used in combination with the expander 2, the plane in which the window portion 110 is located can be made substantially orthogonal to the inspection channel 204 formed by the opening of the leaf 201a and the lower leaf 201b, whereby the inspection scope 1 can be made to obtain a preferable photographing angle and photographing field of view. In addition, when the operator grips the grip 202 in a natural form of one hand, the convenience of the operator in operating the dilator 2 and in operating the inspection scope 1 can be improved.

In some examples, the material on the dilator 2 at the location corresponding to the manipulator module 220 may be transparent. Thus, the operator can easily observe the key 221 on the operation module 220 through the expander 2.

In some examples, the expander 2 may have a protruding key profile at a position corresponding to the operation module 220, and the key profile may be elastic and have a preset key stroke, so that an operator may press the key 221 on the inspection scope 1 by pressing the key profile.

In some examples, referring to fig. 6A, 6B, and 6C, the housing 10 may be provided with an interface 102, and the interface 102 may be used for data transmission and charging.

In some examples, interface 102 may be electrically connected to a control module, and interface 102 may be used to transmit data and charge the control module. Thereby, the inspection scope 1 can be data-transmitted and charged through the interface 102.

In some examples, referring to fig. 3, the inspection scope 1 may further include a silicone gasket 13, and the silicone gasket 13 may be sleeved at the interface 102 to protect the interface 102.

In some examples, the examination mirror 1 may also have a wireless charging coil. This enables the inspection mirror 1 to be charged wirelessly. In some examples, the inspection scope 1 may also be in data transmission with an external device via bluetooth.

In some examples, the external device that interacts with the inspection scope 1 may include a cell phone, tablet, notebook, desktop computer, or other device with a display screen.

In some examples, the control module may include an image processor for processing the captured image. In some examples, when the inspection scope 1 performs data transmission with an external device through the interface 102 or wireless bluetooth, an image acquired through the image processor process may be directly displayed on the external device. Therefore, the operator can conveniently observe and diagnose the checked part in real time.

In some examples, the external device may include software that can interact with the inspection scope 1, and the software can manipulate the inspection scope 1. In this case, by manipulating the software on the external device, the operation of the inspection mirror 1 can also be achieved, whereby the use of the inspection mirror 1 can be made more convenient and diversified.

In some examples, referring to fig. 3 and 7, the inspection scope 1 may further include a transmission line 50, and the transmission line 50 may be detachably connected to the interface 102. In this case, the picture taken by the inspection mirror 1 can be transmitted through the transmission line 50, and the power supply can also be connected to supply power to the inspection mirror 1 through the transmission line 50.

In some examples, referring to fig. 7, the inspection scope 1 may be connected to the computer 3 via a transmission line 50 and upload the captured image to the computer 3, the computer 3 presenting the image on the display screen 31 in real time. In this case, the operator can acquire the lesion position and the lesion feature comparatively intuitively by looking at the image displayed on the display screen 31. This can improve the diagnosis efficiency of the operator.

In some examples, referring to fig. 2 and 6B, the housing 10 may have a protrusion 104, and the protrusion 104 may be disposed at an end remote from the window portion 110. In this case, when the operator holds the housing 10, the operator applies a force in a direction away from the window 110 to disengage the scope 1 from the engagement with the expander 2, and the protrusion 104 can apply a reaction force against the operator's hand, so that the scope 1 can be disengaged from the expander 2 more easily.

In some examples, the tab 104 may be an annular step or flange formed by the housing 10 at an end remote from the window portion 110. In some examples, the annular step or flange may be one or half of a turn around the circumference of the housing 10. This can improve the convenience of manually separating the scope 1 from the dilator 2.

In some examples, the tab 104 may be provided on the first housing component 11. In other examples, the tab 104 may also be provided on the second housing assembly 12. In some examples, the tab 104 may be provided on the first housing component 11 and the second housing component 12.

In some examples, referring to fig. 6B, the housing 10 may have a clamping portion 103 thereon, and the clamping portion 103 may be disposed on an outer surface of the housing 10. In some examples, the snap 103 may be a protrusion formed on an outer surface of the housing 10.

In some examples, the inner wall of the receiving cavity of the grip 202 may be formed with a clamping groove, which may be mated with the clamping portion 103. Specifically, when the inspection scope 1 is placed in the accommodating cavity of the grip portion 202, the clamping portion 103 of the housing 10 may be clamped with the clamping groove of the accommodating cavity. In this case, a relatively close contact can be formed between the scope 1 and the accommodation chamber, so that the fitting firmness of the scope 1 and the expander 2 can be improved. In addition, the inspection scope 1 and the expander 2 can be easily separated by manual force application.

In some examples, the scope 1 and dilator 2 may be connected in other ways as well. For example, the scope 1 and the dilator 2 may be connected by means of a threaded connection. Specifically, the housing 10 of the inspection scope 1 may have an external thread at an end far from the window portion 110, and the receiving cavity of the holding portion 202 may be formed with an internal thread at a position near the opening 203, and after the inspection scope 1 is placed in the receiving cavity, the inspection scope 1 is fixed in the receiving cavity by rotating the inspection scope 1 so that the external thread and the internal thread form a screw connection. Thereby, the assembly of the scope 1 and the dilator 2 can be completed by means of a threaded connection.

In some examples, the number of turns of the external thread and the internal thread may satisfy: after the inspection scope 1 is fixed in the accommodating cavity of the holding portion 202, the window portion 110 of the inspection scope 1 may be attached to the observation window 205 of the holding portion 202.

In some examples, referring to fig. 3, the inspection scope 1 may also have an indicator light 430. The indication lamp 430 may have an indication function. This can better present the current operation state of the inspection mirror 1.

In some examples, indicator lights 430 may emit different colors of light or flash at different frequencies of light. Specifically, the indicator lamp 430 may indicate the current state of the inspection mirror 1 by emitting lights of different colors or by blinking frequency or the like. Thereby, the operator can easily grasp the operation state of the inspection mirror 1. For example, when the lighting module emits blue light for illumination, the indicator light 430 may emit the same indicator light as the current color of the lighting module.

In some examples, the indicator light 430 may be illuminated or color changed by the key 221. In some examples, indicator light 430 may be used to indicate whether inspection scope 1 is active and to provide feedback on possible failure of inspection scope 1.

In some examples, referring to fig. 1, the housing 10 may have an indicator light aperture 112 thereon. In some examples, indicator light 430 may include a light guide post 431 (see fig. 3). The light guide 431 may serve to limit a propagation path of light so that a path of light beam irradiated from the inside of the case 10 to the outside of the case 10 is parallel to a length direction of the light guide 431. In some examples, one end of the light guide post 431 may be connected to the indicator light hole 112.

In some examples, the light guide post 431 may have a sealing ring 432 (see fig. 3) at the location where it connects with the indicator light hole 112. This can provide a good sealing property at the portion where the light guide pole 431 is connected to the indicator hole 112, and reduce the possibility of liquid penetrating into the inspection scope 1.

In some examples, the number of the indicator lights 430 may be plural, and the plurality of indicator lights 430 may be integrated into the operation module 220, that is, the indicator lights 430 may be provided on the keys 221 on the operation module 220. In some examples, different keys 221 may have key indicia thereon that are transparent to the light of indicator lights 430.

In some examples, when the inspection mirror 1 is turned on, the on/off button 221 of the operation module 220 is pressed, and the light of the on/off button 221 is turned on to display that the inspection mirror 1 is in the on operation state. When the inspection mirror 1 is turned off, the on-off button 221 of the operation module 220 is pressed, and the light on the on-off button 221 is turned off to prompt that the inspection mirror 1 is turned off.

In other examples, the lights of the keys 221 may also provide a reference for an operator to see the specific position of each key 221 during use of the inspection scope 1. Thereby, the process of operating the inspection mirror 1 can be visualized and simplified.

In some examples, the inspection scope 1 may further include a storage module that may be used to store images and videos captured by the camera module. Therefore, the subsequent copying and analysis of the images and the videos can be facilitated.

In some examples, the images and videos stored by the storage module may be transmitted to the computer 3 via the transmission line 50 and reviewed on the display screen 31.
