Japanese Utility Model Publication No. 61-38580 JP 2003-52718 A JP 2003-325595 A

  By the way, when performing dental care using the microscope as described above, the surgeon positions the microscope near the upper part of the oral cavity of the patient who is supine on the medical table and performs focusing, etc. Medical examination is performed while observing the affected area. As described above, the medical table can be moved up and down or the back plate sheet can be tilted, and the operator can adjust the vertical position of the medical table and the inclination angle of the back plate sheet so as to facilitate medical treatment. To give medical care. However, after positioning the microscope as described above, the patient's head hits the microscope if the medical table is moved up and down or the backplate sheet is tilted by unexpectedly operating the foot controller or the like. It can also be irritating, and it can also cause fear to the patient. In addition, it may be necessary to move the medical table up and down at the time of focusing, but in such a case, the normal operating speed of the medical table does not match the focusing speed, It is pointed out that it is difficult to focus accurately. Moreover, since the microscope may suddenly approach in front of the eyes, the patient will be forced to feel anxiety.

  In the case of the dental examination table with a microscope shown in Patent Literature 1 and Patent Literature 2, when performing dental examination using the microscope, the operation of the examination table is not different from the normal operation. Therefore, it was impossible to deny such problems. In particular, the dental clinic table and the microscope are different manufacturers, so the surgeon (user) will purchase and use them individually. It was to be entrusted to the operation of the surgeon. In addition, Patent Document 3 discloses that the patient can be moved by gently changing the acceleration and deceleration at the time of starting, stopping, or steady movement during the up-and-down movement of the medical table or the tilting operation of the back plate sheet. A medical examination table is disclosed that does not give fear. However, it is not a medical medical device intended for medical treatment using a microscope, and therefore does not directly lead to the solution of the above problems.

  The present invention has been made in view of the above, and a medical medical device provided with a microscope that can ensure safety when performing medical treatment using a microscope or can also ensure the accuracy of focusing. The purpose is to provide.

A medical medical device according to the present invention includes a medical table having at least a seat seat that can be moved up and down, a microscope unit including a microscope main body movable to a predetermined medical area on the medical table, A medical medical device having a control unit and whose medical target is a patient's head , wherein the medical table includes a headrest, and detects whether the microscope body is in the predetermined medical area A non-contact type sensor member, a recognition member constituting the non-contact type sensor member is installed in the headrest or its vicinity, and the non-contact type sensor recognized members constituting the member, the mounted near portion of the microscope main body, wherein, the detecting means microscope present When the operation table is instructed while detecting that the patient is in the predetermined clinical area, the seat seat of the medical table is set in advance so as to have an ascending / descending speed significantly lower than a normal ascent / descent speed. Operation control is performed according to a predetermined operation mode.

In addition, a medical medical device according to the present invention includes a medical table having at least a seat that can be moved up and down, and a microscope unit including a microscope main body movable to a predetermined medical area on the medical table. And a medical care apparatus comprising: a control unit; and a detection unit that detects whether or not the microscope main body is in the predetermined medical area. When the operation table is instructed while the main body is in the predetermined medical area, the operation instruction is invalidated.

  According to the medical treatment apparatus of the present invention, since the treatment table can be moved up and down at least, the surgeon can adjust the vertical position of the treatment table as appropriate so that the patient can easily perform medical work. Can be positioned. In addition, since a microscope unit including a microscope main body movable to a predetermined medical area on the medical table is provided, the operator positions the microscope main body in a predetermined medical area, that is, in the vicinity of the medical object. In addition, precise medical work can be performed while observing the affected part through the microscope body. Then, when there is an operation instruction of the medical table while the detection means detects that the microscope body is in the predetermined medical area, the medical table is operated according to a predetermined operation mode. Therefore, this operation mode is different from the normal operation mode of the clinical table, so that the operation mode matched to the characteristics when using the microscope can be used to optimize the medical treatment using the microscope. Can measure. For example, if the predetermined operation mode is an operation mode configured to operate the medical table at a speed slower than the normal operation speed, the user can focus by moving the medical table up and down while looking into the microscope. Can be easily performed. In addition, at this time, the microscope body does not suddenly approach the patient on the examination table and cause a sense of fear. Alternatively, if the predetermined operation mode is an operation mode configured to invalidate the operation instruction of the medical table, the operator erroneously instructs the operation of the medical table, that is, an incorrect switch. Even if the operation is performed, since this operation instruction is invalidated, there is no concern that an unexpected situation may occur in which the patient on the medical table suddenly hits the microscope body.

In the present invention, the detection means, because made from the sensor member of the non-contact type, it is possible to configure the detecting means easily. In particular, it is assumed that the couch is provided with a headrest, the recognition member that constitutes the sensor element of the non-contact type is assumed to be installed in the headrest or its vicinity, medical areas of the patient's head In this case, the safety is ensured more accurately. The configuration in this case, recognition target member constituting the sensor element of the non-contact type, since it is assumed that is attached to the vicinity of the microscope body, the microscope body, the sensor element Therefore, a complicated incidental member, for example, electric wiring or the like is not required, and the configuration of the detection means is simplified even when the microscope unit and the medical table are provided by different manufacturers. Here, as a recognition target member, so-called RFID (Radio)
(Frequency Identification) tags or magnetic materials, and RFID readers or magnetic sensors are used as recognition members, which can be easily obtained on the market.

In addition, as a non-contact type sensor member , instead of the recognition member and the recognition target member, if the change of the current applied to the light emitting unit provided in the microscope body is detected, the detection means can be configured simply. Can do. In particular, as a device for detecting a change in current, a transformer type or a Hall element type can be employed, and these can be easily assembled. Further, if the sensor member is a non-contact type sensor member , instead of the recognition member and the recognition target member, a light reflection sensor attached in the vicinity of the microscope body, the detection means can be simply configured similarly. can do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a medical medical device according to the present invention will be described below with reference to the drawings. A medical medical device A shown in FIGS. 1 to 3 is a dental medical device, which is roughly a dental medical table 1 and a microscope unit 2 disposed on the side of the medical table 1. Consists of. The medical table 1 includes a seat sheet 11 installed on a base 10 so as to be movable up and down, a back plate sheet 12 tiltably connected to one end of the seat sheet 11, and an upper end portion of the back plate sheet 12. The headrest 13 is attached to be freely tiltable. A tray table 3 is supported on one side of the medical table 1 so as to be horizontally movable, and a spit-on device 4 is attached to the other side. Further, the dental table 4 extends along the side of the spit-on device 4. A light column 5 for light (not shown) is erected. The microscope unit 2 includes hanger arms 21, 22, 23 connected to multi-joints and a microscope main body 20 attached to the tip thereof. The base part of the hanger arm 21 is attached to the light column 5 so as to be able to turn horizontally, and the joint part of the hanger arm 21 and the hanger arm 22 and the joint part of the hanger arm 22 and the hanger arm 23 are also horizontally swiveled. It is connected as possible. The anti hanger arm side of the mounting position for the write strut 5 of the hanger arm 21, the balance weight 27 is protruded, stability and smoothness of the horizontal turn of the hanger arm 21, 22 and 23 is Fig et al. With such articulated hanger arms 21, 22, and 23, the microscope body 20 is positioned in the vicinity of the upper position of the headrest 13 of the medical table 1, and the oral cavity of a patient (not shown) supine on the medical table 1 Can be observed. The microscope main body 20 is a known microscope (microscope) provided with an eyepiece, an objective lens, a focusing mechanism, and the like, and is positioned by the operator operating the handle 20a.

  An RFID tag (recognition target member) 61 is attached to the hanger arm 23 in the vicinity of the microscope body 20, and an RFID reader (recognition member) 62 is installed on the upper surface side within the thickness of the headrest 13. The RFID tag 61 and the RFID reader 62 constitute a non-contact sensor member (detecting means) 6. The RFID tag 61 is attached to the hanger arm 23 by an attachment band or the like. The RFID comprising the RFID tag 61 and the RFID reader 62 receives the signal generated by the IC chip incorporated in the RFID tag 61 when the RFID tag 61 exists in a predetermined radius region centered on the RFID reader 62. The reception information is sent out. In FIG. 1, the predetermined radius area is indicated by Z, and this radius area Z is based on the characteristics of the RFID reader 62, and usually has a radius of 30 to 50 cm. The radius area Z is defined as a predetermined medical area, and is hereinafter referred to as a predetermined medical area Z.

  Although FIG. 1 shows an example in which the RFID reader 62 is installed at a position close to one side of the headrest 13, the RFID reader 62 may be installed in the center of the headrest 13 or in the vicinity of the headrest 13. Further, the RFID tag 61 may be fixed to the outer surface of the microscope body 20 with a double-sided tape or the like. Furthermore, instead of the RFID tag 61 and the RFID reader 62, it is also possible to use a non-contact type sensor member composed of a magnetic body (magnet) and a magnetic sensor.

  In the dental treatment apparatus 1 having the above-described configuration, when performing dental care using a microscope, an operator (not shown) steps on the foot controller 14 and, as shown in FIGS. In addition, the height and the inclination angle of the back plate sheet 12 are adjusted to positions appropriate for the medical work. Then, the respective hanger arms 21, 22, and 23 of the microscope unit 2 are horizontally turned to position the microscope body 20 on the oral cavity of a patient (not shown) who lies on the medical table 1. When the RFID tag 61 reaches the medical area Z, the RFID reader 62 detects this and sends the detection result to a CPU (control unit) 7 described later. FIG. 4 is a control block diagram, and detection information detected by the RFID reader 62 is sent to the CPU 7 as a control unit. The CPU 7 recognizes that the microscope body 20 is in the medical area Z based on the sent detection information. The CPU 7 includes various instruments (such as a chair driving means 15 for driving a vertical raising / lowering mechanism of the seat seat 11 and a tilting mechanism (not shown) of the back plate seat 12 and the tray table 3 detachably held). An instrument driving means 16 for driving an unillustrated) is connected, and the driving of the chair driving means 15 and the instrument driving means 16 is controlled by a foot operation of the foot controller 14. As the chair drive means 15, a hydraulic drive mechanism as disclosed in Patent Document 3 is employed. The CPU 7 is connected to display means 30 (not shown in FIGS. 1 and 2) including a display device installed on the tray table 3 or the like. The display means 30 is provided with an X-ray image of the affected part, a display part such as an image by an imaging means (not shown), a touch switch, and the like. Further, the observation image of the affected part by the microscope may be displayed after image processing.

  As described above, while the CPU 7 recognizes that the microscope main body 20 is in the medical area Z based on the detection information of the RFID tag 61 by the RFID reader 62, the foot controller 14 is operated by the surgeon. When an operation command is issued to the chair drive means 15, the CPU 7 controls the operation of the chair drive means 15 based on a predetermined operation mode. As this predetermined operation mode, for example, the chair driving means 15, that is, an operation mode configured to operate the medical table 1 at a speed slower than a normal operation speed, or the chair driving means 15, That is, an operation mode configured to invalidate an operation instruction to the medical table 1 is set. FIG. 5 shows the change in the lifting speed when the seat sheet 11 of the medical table 1 moves up and down in the former operation mode, in contrast to the change in the lifting speed of the seat sheet 11 during normal dental care without using a microscope. It is a time chart figure shown. As described above, the hydraulic drive mechanism disclosed in Patent Document 3 is adopted as the chair drive means 15, and due to the structural characteristics of the hydraulic valve used in the hydraulic drive mechanism, the chair drive means 15 is moved up and down immediately after the operation instruction operation. After the acceleration gradually increases and then moves up and down at a constant acceleration, the acceleration gradually decreases and is maintained at a predetermined lifting speed. Immediately after the operation stop instruction is given, the deceleration gradually increases, and after that, the vehicle gradually moves up and down at a constant deceleration, and then the deceleration gradually decreases and completely stops. As described above, the acceleration and deceleration are gradually increased at the time of start and stop, and then gradually decreased, whereby the shock at the time of start and stop for the patient on the clinical table 1 can be alleviated.

  And as shown in FIG. 5, the raising / lowering speed at the time of normal use of the seat 11 is set fast, and the efficiency of medical treatment work is achieved by this. The raising and lowering operation of the seat 11 during normal use is mainly performed at the start of medical treatment after guiding the patient and supine on the medical table 1 or when the patient is withdrawn after completion of the medical treatment. From the viewpoint of improving efficiency, it is desirable to set the raising / lowering speed faster in this way. In addition to this, the tilting operation of the back plate sheet 12 is often performed when gargle is performed during medical treatment. In this case as well, it is desirable to set the tilting speed fast in order to improve the efficiency of medical work. . On the other hand, in the case of medical work using a microscope, the height of the seat sheet 11 and the inclination angle of the back plate sheet 12 are adjusted before the microscope body 20 is positioned in the predetermined medical area Z. . Accordingly, in this case, the seat seat 11 is raised and lowered and the back plate seat 12 is tilted at a normal speed. Then, after the microscope body 20 is positioned in the predetermined medical area Z, the microscope body 20 is located in front of the eyes of the patient who is supine on the medical table 1. When there is an ascending operation instruction or the like and the seat 11 is raised at a normal speed, the microscope body 20 suddenly approaches the patient's eyes, and the patient feels fear. Therefore, in the example of FIG. 5, when the microscope is used, that is, while the microscope body 20 is in the medical area Z, the raising / lowering speed of the seat 11 is set to be significantly slower than that during normal use. In this way, the patient can be kept from fear.

  As described above, as an example in which the seat seat 11 is moved up and down while the microscope body 20 is in the medical area Z, precise focusing is performed by a focusing mechanism incorporated in the microscope body 20. However, there is a case where it is necessary to raise and lower the seat 11 as a rough focus in the previous stage. In this case, if the seat 11 is moved up and down at a normal lifting speed, it is difficult to focus and this impairs the efficiency of the medical work. Therefore, when the medical work using the microscope is performed, It is extremely useful to set the lifting speed slower. Further, during the medical work, it may be necessary to readjust the height of the seat 11 according to the medical condition, or the operator may operate the foot controller 14 by mistake. But it can give the patient a sense of security and trust. In the example of FIG. 5, a change pattern of the raising / lowering speed of the seat 11 is shown. However, an operation mode in which a change pattern of the tilting speed of the backboard seat 12 is combined with this is set, and the microscope body 20 While in Z, it is also possible to control the operation of raising and lowering the seat 11 and tilting the back plate 12 based on this operation mode. In addition, if the operation mode is set to invalidate any operation instruction even if these operation instructions are issued while the microscope body 20 is in the medical area Z, the above focusing is performed. However, it is impossible to readjust the height and the like during medical work, but the patient on the medical table 1 can receive medical care without worrying about fear.

  As shown in FIG. 4, the instrument driving means 16 is also connected to the CPU 7, and the instrument driving means 16 is controlled differently from the normal operation while the microscope body 20 is in the medical area Z. Can be configured. That is, dental treatment using a microscope is mainly used for root canal treatment that requires precise treatment. In this root canal treatment, a micromotor handpiece, a vacuum syringe, and a three-way syringe are usually used, and an air turbine handpiece is not used. Therefore, while the microscope body 20 is in the medical area Z, a microscope is used. The motor handpiece, the vacuum syringe, and the three-way syringe can be used, but the air turbine handpiece can be set so that it cannot be used. Accordingly, even if an operator tries to use the air turbine handpiece by mistake during a medical work using the microscope, it is possible to prevent the air turbine handpiece from operating.

  FIG. 6 shows an example in which the detection means 6 includes a light reflection type sensor 63 as a non-contact type sensor member. In this example, the light reflection type sensor 63 is attached to the vicinity of the microscope body 20 in the hanger arm 23. When there is a detection target that reflects light within a predetermined range (optical path), the light reflection sensor 63 detects the reflected light and sends out the presence of the detection target as detection information. As the detection target in this case, the surface of the headrest 13 or the patient's face on the headrest 13 or the like is applied, and a reflection member is attached to an appropriate part in the vicinity of the headrest 13 to detect the detection target. It is also possible to do. Also in this embodiment, when the light reflection sensor 63 detects a detection target in the medical area Z, the CPU 7 sets the medical table 1 according to a predetermined operation mode based on this detection information in the same manner as described above. By controlling the operation of No. 1, the same effects as described above can be obtained.

  FIG. 7 shows an example in which the non-contact type sensor member as the detection means 6 is constituted by a different one from the above. That is, the microscope body 20 includes a light emitting unit 24 that irradiates an observation target, and an illumination control unit 25 that controls the light emission of the light emitting unit 24. In this example, the light emitting unit 24, the illumination control unit 25, and the like. Current detecting means 64 for detecting the current flowing through the signal line 26 is provided as the detecting means 6. As the current detection means 64, a transformer type that detects a magnetic field formed by a current flowing in an electric wire (signal line) or a Hall element type that converts a magnetic field strength into a voltage signal by the Hall effect is adopted. The The operator turns on and off the light emitting unit 24. When the light emitting unit 24 is turned on during a medical operation, the microscope body 20 is positioned in the medical area Z, and the microscope body 20 is turned on. This is when the affected area is observed. Therefore, the detection information that the light emitting unit 24 is turned on by the current detection means 64 is sent to the CPU 7 as information that the microscope body 20 is substantially in the medical area Z. The CPU 7 controls the operation of the medical table 1 according to a predetermined operation mode in the same manner as described above when there is an operation instruction of the medical table 1 while recognizing the detection information. As a result, the same effect as described above can be obtained.

  8 and 9 show an example in which the detection means 6 is composed of a contact type sensor member. The detection means 6 includes a micro switch 65 and an action piece 66 that acts on the micro switch 65. Between the hanger arms 21 and 22 constituting the swivel mechanism of the microscope unit 2, a vertical support 22 a fixed to the base of the hanger arm 22 is fixed to the tip 21 a of the hanger arm 21 via a bearing 22 b. They are connected to each other by being rotatably supported about a vertical axis. In the illustrated example, the microswitch 65 is fixed to the hanger arm 21 side, and the action piece 66 is formed on the vertical column 22a side. The action piece 66 has a fan shape in plan view, and acts on the microswitch 65 by rotating about the tip 21a of the hanger arm 21 of the vertical support 22a. Send on signal. 9A and 9B show a state where the action piece 66 does not act on the micro switch 65, and FIGS. 9C and 9D show a state where the action piece 66 starts acting on the micro switch 65. Is shown. The range in which the action piece 66 acts on the microswitch 65 is a range corresponding to the arc length region Y of the action piece 66 as shown in FIG. 9B, and the range other than the arc length region Y is the action portion. This is a range where the piece 66 does not act on the microswitch 65. Accordingly, if the microscope body 20 is set so as to be located in the medical area Z when the action piece 66 is in the range where it acts on the micro switch 65, the detection information by the micro switch 65 is sent to the CPU 7, The same operation control as described above can be performed. In the illustrated example, a stopper 21b is provided on the hanger arm 21 side, and the action piece 66 hits the stopper 21b as the vertical column 22a rotates, thereby preventing the 360 ° rotation of the vertical column 22a.

  In the example shown in FIGS. 8 and 9, the detection means 6 is provided at the connection portion between the hanger arms 21 and 22, but the attachment portion of the hanger arm 21 with respect to the light column 5 and the connection portion between the hanger arms 22 and 23 are provided. May be provided with similar detection means. Thus, if it is configured to determine that the microscope body 20 is in the medical area Z under the AND condition of the three detection means provided at three locations, more accurate detection information can be obtained. It is done. Further, in the illustrated example, the micro switch 65 is provided on the hanger arm 21 side and the action piece 66 is provided on the hanger arm 22 side, but these can be provided in an opposite arrangement relationship.

  10A, 10B, and 10C show various modifications of the microscope unit that can be employed in the medical medical device A of the present invention. In the above-described embodiment, an example is shown in which the microscope unit 2 is attached to the light column 5 erected on the side of the medical table 1, but the examples of FIGS. 10 (a), 10 (b), and 10 (c) However, it differs from the clinical table 1 in that it does not have a direct support relationship. That is, the microscope unit 2 shown in (a) has the same articulated hanger arms 21, 22, and 23 that are attached to a column 201 that is erected on a movable table 200 with a caster so as to be horizontally rotatable, The microscope main body 20 is attached to the tip of the hanger arm 23. An RFID tag 61 constituting the detection means 6 is attached to the hanger arm 23 in the vicinity of the microscope body 20 in the same manner as described above. Since the microscope unit 2 in this example is supported by a movable table 200 that is movable on the floor surface, when the dental treatment using the microscope is not performed, the microscope unit 2 is stored in one corner of the medical room or in another room. In addition, it can be moved only during use and placed on the side of the clinic. In this case, the detecting means 6 can detect whether or not the microscope body 20 is in the medical area Z regardless of the position on the side near the medical table 1, and the degree of freedom in use. It is noted that is wide.

  In the example shown in FIG. 10B, the microscope unit 2 is the same as the above on the column 203 standing on the floor mount type spit-on device (patient gargle device) 202 installed on the floor of the clinic. It is attached to the horizontal swivel. Furthermore, in the example of FIG.10 (c), the microscope unit 2 is attached to the support | pillar 204 suspended by the ceiling surface of the medical office so that horizontal rotation is possible. These examples are employed when there is no attachment object such as the light column 5 on the side of the medical table 1. In each of the examples shown in FIGS. 10A, 10B, and 10C, the RFID detection unit 6 configured by combining the RFID tag 61 as a recognition target member with the hanger arm 23 and being combined with the RFID reader 62 (not shown) is illustrated. However, a light reflection type sensor 63 as shown in FIG. 6 and a current detection means 64 for detecting a current applied to the light emitting unit 24 as shown in FIG. 7 can also be used. Furthermore, when the microscope unit 2 is attached to a fixed support (supports 203 and 204) as shown in FIGS. 10B and 10C, the contact type as shown in FIGS. It is also possible to use the detection means 6 comprising the sensor member.

  In the above-described embodiment, the dental medical device A has been exemplified. However, in the medical medical device in which various medical treatments such as oral surgery medical treatment, otolaryngology medical treatment, ophthalmic medical treatment, surgical treatment medical treatment, obstetrics and gynecological medical treatment are performed. It is possible to apply the present invention. Therefore, it is natural that the structure of the medical table 1 is a structure according to the medical characteristics of each medical department, and the structure of the microscope unit 2 is also appropriately determined according to the structure of the various medical tables 1, the medical purpose, and the like. Naturally, design changes are made. Furthermore, instead of the light reflection sensor 63, a light transmission sensor can be used as a non-contact sensor member. In this case, a light emitting unit that emits light of a specific wavelength is provided on the microscope unit 2 side, and a light receiving unit that transmits a detection signal when the light of the specific wavelength is detected is provided in the headrest 13 or its vicinity. Can be considered.
