     TECHNICAL FIELD 
     The present invention relates to a medical magnifier device, and particularly to a medical magnifier device suitable for a medical examination in obstetrics and gynecology. 
     BACKGROUND ART 
     Medical magnifier devices such as microscopes and loupes are widely used in a medical examination, a treatment, and surgery by doctors and dentists. In general, since the performance required for the magnifier device varies depending on medical departments, use purposes, and the like, many dedicated devices specialized for respective medical departments, respective use purposes, and the like have been developed. For example, a dedicated magnifier device called a colposcope (uterovaginal magnifier) is used in the obstetrics and gynecology. The colposcope is mainly used for a thorough checkup of uterine cancer screening. 
     Patent Literature 1 proposes a colposcope in which a mirror body can move smoothly and rapidly. The colposcope disclosed in Patent Literature 1 includes a mirror body, a base portion that determines a position of the device as a whole, a vertical movement arm that moves the mirror body in a vertical direction, and a horizontal movement arm that moves the mirror body in a horizontal direction, and the horizontal movement arm includes a parallelogram link mechanism.

     SUMMARY 
     Technical Problem 
     By the way, it is important that the medical magnifier device is compact and easy to use, as well as being able to clearly observe the affected area with a desired size. However, colposcopes for obstetrics and gynecology and microscopes for surgery are large and not easy to use, and are required for further improvement. 
     For example, the colposcope disclosed in Patent Literature 1 is assumed to be able to move the mirror body smoothly and rapidly as compared with the conventional colposcope, but there is still much room for improvement. The conventional colposcope including the technique of Patent Literature 1 can be moved using the caster of the base portion, but it is not preferable to force a doctor to perform such movement work. In the conventional colposcope, the base portion may be unavoidably moved even in a case of focusing on the affected area. Furthermore, since the arm exists between the doctor and the patient to support the mirror body, such an arm becomes an obstacle at the time of medical examination and treatment. In addition, a large colposcope may be difficult to place in position. 
     Solution to Problem 
     A medical magnifier device according to an aspect of the present invention is a medical magnifier device of head-mounted type, and includes: a device body that includes a face pad coming into contact with a face of a user and covers left and right eyes of the user; a fixing member used to fix the device body to a head of the user; an imaging unit that includes a zoom lens attached to in front of the device body and performs digital conversion on a magnified image acquired through the zoom lens; and at least one monitor that is provided in front of the left and right eyes of the user at the inside of the device body and display the magnified image digitally converted by the imaging unit. 
     Advantageous Effects of Invention 
     According to an aspect of the present invention, it is possible to provide medical magnifier device that is compact and easy to use as well as being able to clearly observe an affected area with a desired size.

       FIG. 1  is a perspective view of the medical magnifier device  10  that is an example of an embodiment.  FIG. 2  is a view illustrating a device body  11  of the medical magnifier device  10  as viewed from the inside, and  FIG. 3  is a cross-sectional view of the device body  11 .  FIG. 4  is a view illustrating a mounted state of the medical magnifier device  10 . For convenience of explanation in this specification, a direction along a width direction of a face in the mounted state of the medical magnifier device  10  is referred to as “lateral direction or left-right direction” of the device body  11 , and a direction along a length direction of the face is referred to as “up-down direction” of the device body  11 . 
     As illustrated in  FIG. 1  to  FIG. 4 , the medical magnifier device  10  is a head-mounted magnifier device including: a device body  11  that includes a face pad  12  coming into contact with a face  102  of a user  100  and covers left and right eyes of the user  100 ; and a fixing member used to fix the device body  11  to a head  101  of the user  100 . In the present embodiment, the fixing member includes a belt  60  that is attached to left and right ends of the device body  11 . The belt  60  extends from the left and right ends of the device body  11  to the rear of the head  101  and comes into contact with the back of the head, thereby the medical magnifier device  10  can be mounted on the head. Furthermore, the belt  60  may have a length adjustment function. 
     The medical magnifier device  10  may include an auxiliary belt  61  that serves as the fixing member and comes into contact with the top of the head. The auxiliary belt  61  extends from an upper end of the device body  11  toward the back of the head over the top of the head and is coupled to the belt  60  on the back of the head. In particular, when the weight of the device body  11  is large, a mounting property of the medical magnifier device  10  on the head is improved by the provision of auxiliary belt  61 . 
     The medical magnifier device  10  includes: an imaging unit  20  that includes a zoom lens  22  provided in front of the device body  11  and performs digital conversion on a magnified image acquired through the zoom lens  22 ; and at least one monitor that displays the magnified image digitally converted by the imaging unit  20 . The medical magnifier device  10  includes a pair of monitors  30  which are provided in front of the left and right eyes of the user  100  at the inside of the device body  11 , as the at least one monitor. The medical magnifier device  10  includes a right-eye monitor  30 R and a left-eye monitor  30 L as the monitors  30 . 
     The medical magnifier device  10  is not a device that is supported by the nose and ears as in eyeglasses, but is a goggle-type magnifier device in which the device body  11  is held in front of the eyes by the face pad  12  and the fixing member. Since the device body  11  firmly fits on the face  102  and is stably held in front of the eyes, a medical practice such as a medical examination or a treatment can be performed smoothly, and the user hardly get tired even after long time use. Moreover, the device body  11  covers around the eyes, and thus the visibility of the monitor  30  is improved. Furthermore, the medical magnifier device  10  has various advantages as compared to a colposcope used in obstetrics and gynecology. The description will be given below with regard to this. 
     The device body  11  is a portion on which the imaging unit  20  and the monitor  30  are mounted and to which the belt  60  and the auxiliary belt  61  are attached. The device body  11  is large enough to cover around the both eyes of the user  100 , for example, has a vertical length sufficient to cover from a lower part of a forehead to an upper part of a cheek and a lateral length that is the same width as that of the face. In addition, the device body  11  has a thickness to a certain extent even in a front-rear direction so as to secure a mounting space for the imaging unit  20  and the monitor  30 . The device body  11  is in a state of protruding forward about 50 mm to 150 mm from the face  102  of the user  100 , for example. 
     The device body  11  includes a front surface portion  11   a  to which the zoom lens  22  is attached. Moreover, the device body  11  preferably includes a lateral surface portion  11   b  that is formed to extend backwardly from both left and right ends of the front surface portion  11   a  and to cover up to the vicinity of temples of the user  100 . When the device body  11  is mounted to cover a lateral side of the face, a good fit feeling can be obtained. The front surface portion  11   a  may be formed substantially flat in the up-down direction and the lateral direction, and may be gently curved forward. The device body  11  is curved outward from boundary portions between the front surface portion  11   a  and the respective lateral surface portions  11   b , and the boundary portion is rounded, but may have an angular shape with an edge. 
     In addition, the device body  11  preferably includes an upper surface portion  11   c  and a lower surface portion  11   d  that are formed to extend backwardly from both upper and lower ends of the front surface portion  11   a  and to cover upper and lower sides of eyes, respectively. In particular, when the upper surface portion  11   c  is provided, the visibility of the monitor  30  is improved and a good fit feeling is obtained. The device body  11  is preferably made of an opaque material except for a window portion  17  to be described below, and is suitably made of a resin in consideration of lightness, workability, and the like. 
     The device body  11  includes the face pad  12  coming into contact with the face  102  of the user  100  as described above. The face pad  12  is made of foam, elastomer, or rubber that is elastically deformed when coming into contact with the face  102 . In the present embodiment, a recess portion  16  is formed in an inner part of the device body  11  facing the user  100  so as to avoid interference with the nose. The face pad  12  is provided at an inner end of the device body  11 , excluding the part where the recess portion  16  is formed. The face pad  12  is provided along edges of the respective lateral surface portions  11   b , the upper surface portion  11   c , and the lower surface portion  11   d  of the device body  11 , for example. 
     The zoom lens  22  is provided at a center, a left side, or a right side on the front surface portion  11   a  of the device body  11  so as to protrude forward. As illustrated in FIG.  3 , a main body  21  of the imaging unit  20  and the monitor  30  are disposed in a space S formed between the front surface portion  11   a  and the inner end of the device body  11 . In the present embodiment, the monitor  30  is installed on a surface (rear side) of the main body  21  facing the user  100 . That is, the imaging unit  20  is formed integrally with the monitor  30 . 
     A pair of eyepieces  13  may be disposed in the space S of the device body  11 . The pair of eyepieces  13  includes a right-eye eyepiece  13 R and a left-eye eyepiece  13 L. In an example illustrated in  FIG. 1 , an inter-eyepiece distance adjusting portion  18  is provided on the upper surface portion  11   c  of the device body  11  to adjust a distance between the eyepieces  13 R and  13 L. Further, eyepiece focus adjusting portions  19 R and  19 L are provided on the upper surface portion  11   c  of the device body  11  to adjust a focus of the eyepieces  13 R and  13 L. On the upper surface portion  11   c , the inter-eyepiece distance adjusting portion  18  is disposed at a position corresponding to a point between the left and right eyes of the user  100 , and the eyepiece focus adjusting portions  19 R and  19 L are respectively disposed on the left and right sides of the upper surface portion  11   c  with the inter-eyepiece distance adjusting portion  18  interposed therebetween. 
     The inter-eyepiece distance adjusting portion  18  and the eyepiece focus adjusting portions  19 R and  19 L are configured by a dial installed in the device body  11 . The dial is installed to partially protrude upwardly from the upper surface portion  11   c . The user  100  can narrow or widen a gap between the eyepieces  13 R and  13 L according to a gap between user&#39;s eyes by turning the inter-eyepiece distance adjusting portion  18 . In addition, the user  100  moves the eyepieces  13 R and  13 L in the front-rear direction by turning the eyepiece focus adjusting portions  19 R and  19 L, and thus can adjust the focus of each lens separately. Furthermore, the inter-eyepiece distance adjusting portion  18  and the eyepiece focus adjusting portions  19 R and  19 L may be provided as an operation switch of a remote controller  40  to be described below. 
     In the space S of the device body  11 , a pair of monitors  30  are disposed in front of the pair of eyepieces  13 . In a state where the medical magnifier device  10  is mounted, the eyepiece  13 R and the monitor  30 R are sequentially present in front of the right eye of the user  100 , and the eyepiece  13 L and the monitor  30 L are sequentially present in front of the left eye. In the space S, a partition wall portion  15  is formed along the front-rear direction at the center in the lateral direction of the device body  11 . The partition wall portion  15  isolates the monitors from each other such that the monitor  30 R is not seen by the left eye and the monitor  30 L is not seen by the right eye. 
     The device body  11  preferably includes the window portions  17  that are provided at both left and right sides with the imaging unit  20  interposed therebetween and allow the user  100  to visually recognize left and right sides. The device body  11  is preferably mounted so as to cover around both eyes from the viewpoint of the mounting property and the visibility improvement of the monitor  30 , but when the entire device body  11  is made of an opaque material, surroundings may not be visible at all, which is inconvenient for medical practice. When the device body  11  includes the window portion  17 , surrounding situations can be confirmed without removal of the device one by one, and the medical magnifier device  10  is easier to use. 
     The window portion  17  may be an opening portion formed in the device body  11 , and is preferably made of a resin having good translucency such as an acrylic resin or polycarbonate. Moreover, the acrylic resin and the polycarbonate are also excellent in heat resistance, thereby being also suitable for sterilization treatment of the device body  11 . The window portion  17  is preferably formed on each of the lateral surface portions  11   b , and is provided in such a manner that a transparent resin material is applied to a part or all of each lateral surface portion  11   b . On each of the lateral surface portion  11   b , the window portions  17  are provided, for example, from the boundary portions with the curved front surface portion  11   a  or both the left and right sides of the front surface portion  11   a  to positions corresponding to points just beside the eyes. When the window portions  17  are provided to extend to both the left and right sides of the front surface portion  11   a , the user  100  can visually recognize the left and right front in the state where the medical magnifier device  10  is mounted. 
     The window portions  17  are preferably formed below the positions at least corresponding to the points just beside the eyes. Since an instrument  103  (see  FIG. 5  to be described below) or the like used for the medical examination is generally located below the eye level of the user  100 , it is preferable that the window portion  17  is formed at least below the eye level. For example, on each of the lateral surface portions  11   b  of the device body  11 , the window portion  17  is formed below the lower end of the fixing member such as the belt  60 . In the present embodiment, in order to make the left and right visibility better, the window portions  17  are also formed greatly in the up-down direction of the device body  11  across the boundary portion of the lower surface portion  11   d  from the boundary portion of the upper surface portion  11   c  so as to be located above the eye level. 
     In addition, the window portion  17  may have a light control function capable of changing transparency. In this case, the window portion  17  can be made opaque at the time of confirmation of the magnified image acquired by the imaging unit  20 , and can be made transparent at the time of confirmation of surroundings, for example, a search for the instrument  103 . The remote controller  40  to be described below may be provided with an operation button used to change the transparency of the window portion  17 . 
     From the viewpoint of visibility of the monitor  30 , most of the front surface portion  11   a  and the upper surface portion  11   c  of the device body  11  are preferably made of an opaque material. For example, a transparent portion such as the window portion  17  or an opening portion may be provided on the lower surface portion  11   d  so that the hand can be seen. 
     The medical magnifier device  10  may have a configuration capable of performing a heat sterilization treatment. In the heat sterilization treatment, for example, the medical magnifier device  10  is exposed to a high-temperature steam environment. For this reason, the medical magnifier device  10  to be subjected to the heat sterilization treatment preferably has a structure in which the imaging unit  20  can be separated from the device body  11 , that is, a structure in which the imaging unit  20  is detachable from the device body  11 . In addition, the device body  11  and the belt  60  are made of a resin having high formability and heat resistance such as an acrylic resin, polycarbonate, polyester, or polyamide. The belt  60  may be made of leather. 
     As described above, the imaging unit  20  includes the zoom lens  22 , and has a function of performing digital conversion on the magnified image acquired through the zoom lens  22 . The imaging unit  20  includes the main body  21  that incorporates an imaging element such as a CCD or a CMOS, as in a digital camera or a camera phone. The zoom lens  22  is installed in front of the main body  21 , light passing through the zoom lens  22  is incident on the imaging element of the main body  21  and is converted into a digital signal, and the converted digital signal is displayed on the monitor  30 . The main body  21  is provided with, for example, an image processing engine and a storage portion that stores data of the digitally converted magnified image. 
     The imaging unit  20  may be configured to manually adjust a focus, but preferably has an autofocus function. In this case, the main body  21  incorporates an autofocus sensor, a motor, a control microcomputer, and the like. The main body  21  may be provided with a mechanical shutter for taking a still image. 
     The zoom lens  22  is a lens used to acquire a magnified image of an affected area, and has an optical zoom function. By the optical zoom lens  22 , a clear magnified image of the affected area can be obtained. The magnification of the zoom lens  22  is set in an appropriate range depending on a use purpose; for example, the magnification of the zoom lens is set to 5 times to 40 times, and preferably 5 times to 20 times in the use purpose of a medical examination in obstetrics and gynecology. In a magnifier device dedicated to the medical examination in obstetrics and gynecology, the magnification may be set in a narrow range such as 10 times to 15 times. Furthermore, the imaging unit  20  may have a digital zoom function. 
     The zoom lens  22  is preferably provided at a position corresponding to a point between the left and right eyes of the user  100 , on the front surface portion  11   a  of the device body  11 . In the present embodiment, the device body  11  has a bilaterally symmetrical shape, and the zoom lens  22  is provided at the center, the left side, or the right side in the front surface portion  11   a . In order to obtain images corresponding to the monitors  30 R and  30 L, two zoom lenses  22  can be provided, but one zoom lens  22  is preferably provided in consideration of the lightness of the device. 
     The monitor  30  includes the right-eye monitor  30 R and the left-eye monitor  30 L, and is a so-called dual monitor in which a right-eye image is displayed on the monitor  30 R and a left-eye image is displayed on the monitor  30 L. In the present embodiment, the monitors  30 R and  30 L are installed on the surface facing the rear of the main body  21 , and the respective monitors are isolated from each other by the partition wall portion  15 . For example, a liquid crystal monitor or an organic EL monitor is applied to the monitor  30 . 
     For example, the magnified image acquired by the zoom lens  22  and the imaging element is processed for the monitor  30 R and the monitor  30 L by the image processing engine of the imaging unit  20 , and thus the magnified image of the affected area displayed on the monitor  30  is generated. 
     The medical magnifier device  10  preferably further includes a light  23  provided in front of the device body  11 . For example, an LED is applied to the light  23 . A separate light may be used when it is necessary to illuminate the affected area brightly, but the mounting of the light  23  on the device body  11  makes the use of the medical magnifier device  10  easier. The light  23  is preferably provided above the zoom lens  22 , on the front surface portion  11   a  of the device body  11 . 
     The medical magnifier device  10  preferably further includes a remote controller  40  (hereinafter, referred to as “remocon  40 ”) that is wirelessly connected to the imaging unit  20 . The remocon  40  includes at least a magnification adjustment button  44  used to operate the magnification of the zoom lens  22 . An operation portion may be provided in the device body  11  to perform on/off of the imaging unit  20  and the monitor  30  and adjust the magnification of the zoom lens  22 , but the operability is improved by use of the remocon  40 . Furthermore, the medical magnifier device  10  may have a function of detecting the line of sight of the user  100  and executing various operations. 
     The remocon  40  includes a remocon body  41  that is formed thin and long to be easily gripped. A plurality of operation buttons including the magnification adjustment button  44  are provided on one surface of the remocon body  41 . Examples of the operation portions include a power switch  42  used to turn on and off the imaging unit  20  and the monitor  30 , a light switch  43  used to turn on and off the light  23 , a shutter button  45  used to acquire a still image, and a recording button  46  used to acquire a moving image. 
     The medical magnifier device  10  preferably includes a storage portion that stores the magnified image digitally converted by the imaging unit  20 . In the present embodiment, the storage portion is configured by a memory card  52  accommodated in a memory card slot  50 . The memory card slot  50  is provided, for example, in the imaging unit  20 , and is configured such that the memory card  52  can be inserted from the lower surface portion  11   d  of the device body  11 . The data of the magnified image of the affected area acquired by the imaging unit  20  is retained in the memory card  52 . The medical magnifier device  10  may include a storage portion configured by a hard disk (HDD) or the like. 
     The medical magnifier device  10  may include a power line used to supply power to the imaging unit  20  and the monitor  30 , but is preferably driven by a battery  53  because a cord such as the power line interferes with the medical practice. A battery slot  51  is provided, for example, in the imaging unit  20  and is configured such that the battery  53  can be inserted from the lower surface portion  11   d  of the device body  11 . In addition, the imaging unit  20  is provided with one or a plurality of cable jacks  54  into which cables used to connect to a personal computer, a printer, an external monitor, and the like are inserted. When the cable jack  54  is provided, image data and moving image data can be transmitted to the personal computer and the like via the cable. 
     With reference to  FIG. 5 , a description will be given herein with respect to a method of performing an medical examination in obstetrics and gynecology, in particular, obstetrics and gynecology cancer screening (thorough checkup of uterine cancer screening) using the medical magnifier device  10  including the configuration described above, and an operational effect of the medical magnifier device  10  will be described in detail. 
     In the obstetrics and gynecology, a checkup called colposcopy/colposcope diagnosis has been carried out using a colposcope to confirm the presence or absence of a lesion (inflammation, tumor) and the extent of the lesion. In this checkup, a dedicated instrument is inserted into the vagina, and the cervix and the vaginal wall are magnified several times to several tens of times with a colposcope for observation. In addition, acetic acid application diagnosis is also performed which involves, while looking into the colposcope, lightly pressing a cotton ball soaked in an acetic acid solution against the cervix and the like and observing the change in the lesion (observing the change of the lesion due to clouding by acetic acid), and a biopsy is also performed as needed. Further, hemostasis is also performed when there is bleeding. 
     As described above, the conventional colposcope has a problem that it is large and not so easy to use. On the other hand, according to the medical magnifier device  10  having the above-described configuration, it is possible to perform a simpler and stress-free medical examination while ensuring medical examination accuracy equal to or higher than when the colposcope is used. 
     As illustrated in  FIG. 5 , the medical magnifier device  10  is fixed to a head  101  of the user  100  (hereinafter, referred to as “doctor”) using the belt  60  and the auxiliary belt  61 . The medical magnifier device  10  is mounted in a state where the face pad  12  comes into contact with the face  102  and the device body  11  covers the left and right eyes to fit with the face  102 . Then, the doctor mounted with the medical magnifier device  10  observes the cervix and the vaginal wall by adjusting the zoom lens  22  to an appropriate magnification in a state of turning the zoom lens  22  toward the patient. 
     In the medical examination in obstetrics and gynecology using the medical magnifier device  10 , since the device is fixed to the head  101  of the doctor, there is no need to move the base portion, unlike the colposcope, and an obstacle such as an arm does not exist between the doctor and the patient. Since the focus of the zoom lens  22  is adjusted by autofocus and can also be adjusted by movement of the head  101 , there is no need to perform focusing by moving the base portion, unlike the colposcope. When the colposcope is used, there are disadvantages that the arm between the doctor and the patient interferes with the medical practice and focusing also needs to be performed again by contact with the arm. 
     In the medical examination in obstetrics and gynecology using medical magnifier device  10 , as in the case of using the colposcope, the instrument  103  is inserted into the vagina to widen the vagina, and the cervix and the vaginal wall are observed with a magnification of 10 times to 15 times, for example. In the medical magnifier device  10 , since the monitors  30 R and  30 L are disposed in front of the left and right eyes to display the magnified image of the affected area, the magnified image can be easily observed and the medical examination can be performed with good accuracy. Since the magnified images of the affected area displayed on the monitors  30 R and  30 L are acquired by the optical zoom lens  22  and are digitally converted by the imaging element, the images are bright and clear. In addition, a higher-quality magnified image can be easily obtained using the light  23 . 
     Since the medical magnifier device  10  is firmly fixed to the head  101  and fits with the face  102 , the medical practice using both hands can be performed smoothly, and the user hardly get tired even after long time use. Since the device body  11  is provided with the window portions  17  that allows the left and right sides to be visually recognized, the position of the instrument  103  can be confirmed through the window portions  17 , for example, and the instrument  103  can be handled without removal of the device one by one. Since the window portions  17  are provided only on both the left and right sides of the device body  11  or on both the left and right sides and in the vicinity thereof, the workability can be improved without impairing the visibility of the monitor  30 . 
     In the medical magnifier device  10 , the front can be seen by the zoom lens  22 . However, the zoom lens  22  is used to obtain the magnified image, and thus is not suitable for confirming the surrounding situations. Although it is also considered to provide a lens in addition to the zoom lens  22 , the weight of the device becomes heavy and switching of the image displayed on the monitor  30  is also necessary in this case. 
     The medical magnifier device  10  can be easily operated using the remocon  40 . For example, the magnification of the zoom lens  22  can be adjusted by the operation of the magnification adjustment button  44 . In addition, the still image data of the affected area can be acquired by the operation of the shutter button  45 , and the moving image data can also be acquired by the operation of the recording button  46 . The still image data and the moving image data are retained in the memory card  52 . 
     As described above, the medical magnifier device  10  is more compact and easier to use compared with the colposcope. According to the medical magnifier device  10 , it is possible to perform the medical examination with accuracy equal to or higher than that of the colposcope. The medical magnifier device  10  can be used for the obstetrics and gynecology cancer screening, and is suitable for the thorough checkup of the uterine cancer screening. The medical magnifier device  10  serves as a magnifier device for thorough checkup of uterine cancer screening, for example, and has the excellent effect as described above that is not found in the prior art. 
     As illustrated in  FIG. 6 , the medical magnifier device  10  can also be used for surgery. Similarly to the colposcope, a conventional magnifier device (microscope) used for the surgery is large and not so easy to use. In addition, the surgery for a long time while looking through the microscope is an operation having an extremely high fatigue degree. When the surgery is performed using the medical magnifier device  10 , the fatigue of the doctor can be reduced and the accuracy of the surgery can also be improved. 
     The embodiment described above can be changed in design as appropriate in the range without departing from the object of the present invention. For example, as in a medical magnifier device  10 X illustrated in  FIG. 7 , a helmet-type support portion  63  may be included as the fixing member to cover widely the entire head. The support portion  63  covers the entire head including the front, rear, side, and top of the head, and has a helmet-type shape that is curved along the shape of the head. In the medical magnifier device  10 X, the device body  11  is attached to a front end of the support portion  63 . Since the device body  11  can be supported with the entire head by the support portion  63 , a favorable mounting property is obtained even when the weight of the device body  11  becomes heavy.
