Description

  The present invention relates to an ultrasonic diagnostic apparatus having a rotatable console.

  When an operator operates an ultrasound diagnostic apparatus, there are various modes such as when a patient is lying on a bed or sitting on a chair. Depending on the site, the patient can be diagnosed by applying the probe to the patient in various states. In addition, there are cases where the diagnosis location is a diagnosis room or a hospital room, and a sufficient diagnosis space may not be secured.

  For this reason, the operator may be forced to make a diagnosis with an unstable posture. For this reason, the operator often complains of pain in the arm or neck.

  Therefore, as shown in FIG. 7, a conventional ultrasonic diagnostic apparatus has been proposed and put into practical use in which the console 103 is configured to be rotatable about the console rotating shaft 104 (see FIG. 7). For example, see Patent Document 1).

  Since the console can be rotated, the physical burden on the operator can be reduced by directing the console in a direction that facilitates diagnosis. Moreover, since it leads to improving the accuracy of diagnosis, it is necessary to make the rotation range of the console as large as possible.

  Further, since the ultrasonic diagnostic apparatus is an image diagnostic apparatus, it is necessary to record and store an ultrasonic diagnostic image of the diagnosed patient. There are black and white printers, color printers, video decks and the like as recording / storing means. Recently, DVD recorders and the like have begun to spread.

  Therefore, as a user, a plurality of recording devices (hereinafter referred to as OEM devices) may be connected to an ultrasonic diagnostic apparatus to record an image.

Therefore, in the demand for miniaturization of the ultrasonic diagnostic apparatus, as shown in FIG. 8, there is a case where the OEM device 106 is installed on the mounting portion 105 on the upper portion of the main body 101 as necessary.
JP 2004-624 A

  However, in the conventional ultrasonic diagnostic apparatus shown in FIG. 12, the OEM device 106 must be installed within the rotation range of the console. FIGS. 9 and 10 are diagrams showing the relationship between the console 103 and the OEM device 106. As shown in FIG. 9, if the console 103 is inadvertently rotated, the console 103 may collide with the OEM device 106 and the OEM device 106 may be damaged.

  As shown in FIG. 10, when the OEM device 106 is not mounted on the placement unit 105 at the top of the main body unit 101, it is preferable that the console 103 can be largely rotated. Therefore, it is not effective to restrict the rotation range of the console from the beginning on the assumption that the OEM device 106 is mounted.

  The present invention has been made to solve the conventional problems, and when a device is installed on the placement unit of the ultrasonic diagnostic apparatus, the console is not contacted with the device, and the device is not installed. In some cases, an object of the present invention is to provide an ultrasonic diagnostic apparatus that can freely rotate a console.

With this configuration, when the rotation axis rotation restricting means and the fixture rotation restricting portion come into contact with each other by rotating the operation console, the operator cannot rotate the operation console any more. Can be notified.

  According to the present invention, when the device is placed on the placement portion of the ultrasonic diagnostic apparatus, contact between the console and the device is avoided, and when the device is not placed, the console can be freely rotated. An ultrasonic diagnostic apparatus capable of moving can be provided.

  Hereinafter, an ultrasonic diagnostic apparatus according to an embodiment of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing a configuration example of an ultrasonic diagnostic apparatus according to the first embodiment of the present invention.

  The main body 1 incorporates hardware necessary for processing signals from an ultrasonic probe (not shown). The monitor 2 displays diagnostic images and various information. The console 3 is rotatably installed so that an operator can operate the ultrasonic diagnostic apparatus. The console rotation shaft portion 4 has a function for rotating the console 3. The OEM device 6 is a device such as a VCR or a DVD drive for recording an ultrasonic diagnostic image or the like, and is fixed to the mounting portion 5 of the main body 1 by a fixing tool 7. The fixture 7 is provided with a rotation restricting portion 8 for restricting the rotation of the console rotating shaft portion 4.

  Since the ultrasonic diagnostic apparatus usually has casters and can be easily moved, when the OEM equipment 6 is installed in the ultrasonic diagnostic apparatus, it may fall when moved simply by placing it. .

  Therefore, when the OEM device 6 is installed on the placement unit 5, it is fixed using the fixture 7 as described above. The mounting unit 5 is provided with a screw hole or the like according to the fixture 7, for example, and the fixture 7 is provided with a screw hole or a screw through hole according to the screw hole of the outer casing of the OEM device 6. The fixture 7 fixes the OEM device 6 to the placement unit 5 using the screw holes and screw through holes. In other words, when installing the OEM device 6 on the mounting unit 5, a plurality of fixtures 7 can be exchanged as necessary in addition to changing the position of the fixture 7 corresponding to the size and shape of the OEM device 6. The fixture 7 is required.

  FIG. 2 is a cross-sectional view showing details of the console rotation shaft portion 4 and the fixture rotation restricting portion 8 of the ultrasonic diagnostic apparatus according to the present embodiment. The console rotation shaft portion 4 is provided with a rotation shaft 10 that rotates together with the operation console 3, and the rotation shaft 10 is provided with a rotation shaft rotation restriction portion 11. The console rotation shaft portion 4 is provided with a rotation restriction portion insertion portion 9 into which the fixture rotation restriction portion 8 is inserted.

  3 to 5 are sectional views showing the relationship between the fixture rotation restricting portions 8a and 8b and the rotation shaft turning restricting portion 11 when the console turning shaft portion 4 is viewed from above. FIG. 3 shows a case where the fixture rotation restricting portion 8 is not inserted into the rotation restricting portion inserting portion 9. Therefore, since there is nothing in contact with the rotation shaft rotation restricting portion 11, the rotation shaft 10 can rotate beyond the rotation restricting portion insertion portion 9.

  FIG. 4 shows a case where the fixture rotation restricting portion 8 a is inserted into the rotation restricting portion inserting portion 9. When the rotation shaft 10 rotates counterclockwise, the rotation shaft rotation restricting portion 11 also moves and is restricted from rotating by contacting the fixture rotation restricting portion 8a. Can no longer rotate. Therefore, the console 3 cannot be rotated further.

  FIG. 5 shows a case where a fixture rotation restricting portion 8 b larger than the fixture rotation restricting portion 8 a in FIG. 4 is inserted into the rotation restricting portion inserting portion 9. When the console 3 rotates, the fixture rotation restricting portion 8b and the rotation shaft restricting portion 11 come into contact with each other, and the rotation is restricted. Since the fixing tool rotation restricting portion 8b is larger than the fixing tool rotation restricting portion 8a, the fixing tool rotation restricting portion 8b and the rotation shaft restricting portion 11 come into contact with each other at a small rotation angle, and the rotation range of the console 3 is reduced. Becomes smaller.

  As described above, since the fixture 7 needs to be adjusted to the position of the screw hole of the OEM device 6 or the like, usually, an individual fixture 7 is prepared for each OEM device 6. Therefore, if the shape and size of the fixture rotation restricting portion 8 of the fixture 7 are determined in accordance with the size of the OEM device 6 to be fixed, the operation is performed according to the shape and size of the installed OEM device 6. The rotation range of the table 3 can be set to an appropriate range.

  As described above, according to the ultrasonic diagnostic apparatus according to the first embodiment of the present invention, the position of the rotation shaft rotation restricting portion 11 provided on the rotation shaft 10, the fixture rotation restricting portion 8. If the conditions such as the width of the console 3 and the shape and size of the OEM device 6 are matched, the rotation of the console 3 can be stopped before the console 3 comes into contact with the OEM device 6. Therefore, it is possible to avoid the console 3 from hitting the OEM device 6 and damaging each of them, and at the same time, the console 3 can be rotated until just before contacting the OEM device 6. Furthermore, since there is no worry of colliding when the OEM equipment 6 is not installed, the console 3 can be freely rotated without being restricted, so that improvement in safety and improvement in operability can be realized at the same time. it can.

(Second Embodiment)
FIG. 6 is a cross-sectional view showing the relationship between the rotation shaft rotation restricting portion 11 and the fixture rotation restricting portion 8 of the ultrasonic diagnostic apparatus according to the second embodiment of the present invention.

  The contact detection unit 12 is provided at a position facing the fixture rotation regulating unit 8 of the rotation axis rotation regulating unit 11 and detects contact with the fixture rotation regulating unit 8. The rotation braking unit 13 (rotation braking unit) is a brake that is provided in the console rotation shaft unit 4 and stops the rotation of the rotation shaft 10. Since other configurations are the same as those of the ultrasonic diagnostic apparatus according to the first embodiment, the same reference numerals are given and description thereof is omitted.

  When the rotation shaft 10 is rotated and the contact detection unit 12 comes into contact with the fixture rotation restricting unit 8, the contact detection unit 12 detects this, and the rotation braking unit 13 is connected to the rotation shaft 10. Brake is applied to stop the rotation of the rotation shaft 10. Control from detection to braking is controlled by a device control unit (not shown) or the like.

  Further, when it is detected that the contact detection unit 12 has contacted the fixture rotation restricting unit 8, the monitor 2 (notification unit) is notified by the control of the device control unit (not shown) or the like. It is also possible to notify the operator that the console 3 cannot be rotated any more by displaying a message such as “Cannot rotate the screen”.

  At this time, in addition to the monitor 2, it is also possible to notify that the console 3 cannot be rotated any more, for example, by sound from a speaker (not shown).

  By installing the contact detection unit 12 at a certain distance from the rotation shaft rotation restricting unit 11, it is possible to detect contact before reaching the rotation limit.

  As described above, according to the ultrasonic diagnostic apparatus according to the present embodiment, it is detected that the contact detection unit 12 is in contact with the fixture rotation restricting unit 8, and the rotation braking unit 13 is rotated. Since the rotation of the rotating shaft 10 is stopped by applying braking, the safety can be further improved.

  Furthermore, by notifying the operator that the console 3 cannot be rotated any more, it is possible to prevent the console 3 from being rotated with more force than necessary, thereby improving safety and operability. It can be realized at the same time.

  Note that the contact detection unit 12 may be configured to detect contact between the fixture rotation restriction unit 8 and the rotation shaft rotation restriction unit 11. In the case of this configuration, the contact detection unit 12 is not necessarily arranged in the rotation shaft rotation restricting unit.

  Moreover, in the ultrasonic diagnostic apparatus according to the first and second embodiments, the shape of the fixture rotation restricting portion 8 is not limited to a cubic shape. For example, the shape of the fixture rotation restricting portion 8 can be formed in a Y shape.

  Moreover, although the case where the rotation shaft rotation restricting portion and the fixture rotation restricting portion are convex is shown, even if either the rotation shaft rotation restricting portion or the fixture rotation restricting portion is concave, Similarly, the rotation range of the console can be limited.

  Even when the OEM device 6 is not symmetrical with respect to the straight line connecting the rotation shaft 10 and the fixture rotation restricting portion 8, the shape and size of the fixture rotation restricting portion 8 can be adjusted appropriately. A rotation range can be obtained.

  The ultrasonic diagnostic apparatus of the present invention has an advantage that it can be rotated within a range where the console does not come into contact with other devices, and can be used in the medical field, particularly in ultrasonic diagnosis.
