  Next, the probe container 22 will be described with reference to FIG. FIG. 4A to FIG. 4C are examples of the shape of the probe container 22. The probe container 22 accommodates a probe, and the shape thereof can be freely selected according to the shape and size of the probe or the ease of manufacture. For example, FIG. 4 (A) shows a probe container 22a that has a substantially rectangular box shape and is particularly suitable for storing a probe with its distal end down. Such a probe container 22a can correspond to probes of various shapes.

  FIG. 4B shows a cylindrical probe container 22b having a through hole 40 on the bottom surface, which is particularly suitable for a probe having a wide tip (for example, a convex probe). In the probe container 22b, when the probe is stored so that the front end of the probe faces upward and the rear end of the probe passes through the through hole 40, the probe is caught and held on the bottom surface of the probe container 22b.

  FIG. 4C shows a probe container 22c having a cylindrical shape in which a through hole 40 is provided on the bottom surface as in FIG. 4B, and an inner surface formed in accordance with the shape of the probe. This is particularly suitable for elongated probes such as intracavity probes. Similarly to FIG. 4B, when the probe tip is placed upward and the rear end of the probe is passed through the through hole 40 and stored, the probe is hooked and held on the bottom surface of the probe container 22c. Since the probe container 22c has a small inner diameter, even an elongated probe can be stably held.

  Each of these probe containers 22 has a slit 42 on the side surface for allowing the probe cable to pass therethrough. Further, a screw hole 44 for attaching a fixture described later is formed on the side surface opposite to the slit 42. The periphery of the screw hole 44 is flat so that the fixture 24 can be stably fixed.

  Next, the fixture 24 will be described with reference to FIGS. FIG. 5 is a side view and a perspective view of the fixture 24, and FIG. 6 is a diagram showing a state where the fixture 24 is attached to the probe container 22. FIG. 7 is a view showing a state when the probe container 22 is attached to the rail member 20 with the fixture 24.

  The attachment 24 is for detachably attaching the probe container 22 to the rail member 20, and includes a fitting 50 having a substantially U-shaped cross section and a lock pin 52 attached to the fitting 50. The width from the upper surface 54 to the bottom surface 56 of the metal fitting 50 is slightly larger than the width from the groove 30 to the bottom surface of the rail member 20. Therefore, when the upper surface 54 of the metal fitting 50 is inserted into the groove 30 of the rail member 20, the bottom surface 56 of the metal fitting 50 is positioned immediately below the bottom surface of the rail member 20 (see FIG. 7). Further, at the tip of the upper surface 54 of the metal fitting, an edge portion 54a that is a protrusion for catching on the protrusion portion 32 of the groove 30 of the rail member 20 is formed.

  A bolt hole 60 through which a bolt passes is formed on a side surface 58 connecting the upper surface 54 and the bottom surface 56 of the metal fitting 50. The fitting 24 and the probe container 22 are connected by passing through the bolt hole 60 and screwing the bolt into the screw hole 44 of the probe container 22. The connected state is shown in FIG. If the probe container 22a is large as shown in FIG. 6A, two attachments 24 are attached, and if the probe container 22c is small as shown in FIG. 6B, one attachment 24 is attached.

  As shown in FIG. 6B, in the case of a cylindrical probe container 22c, the fixture 24 is attached via an adapter 26. The adapter 26 is a block body provided between the fixture 24 and the probe container 22 and has an inclined surface 26a. As will be described later, the adapter 26 is provided to adjust the direction of the slit 42 of the probe container 22.

  The lock pin 52 is a pin member that penetrates the bottom surface of the metal fitting 50, and is arranged so that the pin tip 62 faces upward. The pin tip 62 moves up and down by operating the head 64 of the lock pin 52 with a predetermined force or more, and protrudes or is buried from the metal bottom surface 56. When the attachment 24 is attached to the rail member 20, the pin tip 62 is buried from the metal bottom surface 56 so as not to obstruct the attachment. When the position of the fixture 24 is to be fixed, the pin tip 62 is protruded and the pin tip 62 is inserted into one of the engagement holes 36 formed on the bottom surface of the rail member 20 to fix the position. Can do.

  Next, handling of such a probe holder 16 will be described. The user attaches the rail member 20 to one side surface or both side surfaces of the main body portion 12 of the ultrasonic diagnostic apparatus 10 according to the arrangement position of the ultrasonic diagnostic apparatus 10 or the number of probes.

  Further, one or more probe containers 22 are selected according to the number and type of probes, and a fixture 24 is attached to each of them. At this time, in some cases, an adapter 26 is interposed between the fixture 24 and the probe container 22.

  Then, the pin tip 62 of the lock pin 52 of the fixture 24 is buried from the metal bottom surface 56, and the fixture 24 and the probe container 22 attached thereto are attached to the rail member 20. And the fixture 24 and the probe container 22 are moved along the rail member 20, and are moved to a desired position. When the desired position is reached, the lock pin 52 is operated to insert the pin tip 62 into one of the engagement holes 36 of the rail member 20. Thereby, the fixture 24 and the probe container 22 are fixed at the position. Other probe containers 22 are sequentially attached to the rail member 20 in the same procedure.

  Thus, since the probe container 22 is configured to be detachable from the rail member 20, the probe holder 16 including the number and types of probe containers 22 that are easy to use for the user can be obtained. Further, since a plurality of engagement holes 36 are provided, and the lock pin 52 detachably inserted into the engagement hole 36 is provided in the fixture 24, the probe container 22 can be fixed at a desired position. The position, interval, and order of the probe container 22 can be set as desired by the user.

  Further, since the rail member 20 itself is also detachable from the main body 12 of the ultrasonic diagnostic apparatus 10, the probe holder 16 can be installed on any of the right side, left side, and both side surfaces of the main body 12. In addition, since the probe container 22 is attached to the main body 12 via the rail member 20, even if the size and number of the probe containers 22 are changed, it can be easily handled by replacing only the rail member 20. That is, in the conventional patent document 1 and patent document 2, since the probe container is attached to the main body of the ultrasonic diagnostic apparatus, if the number or shape changes, the main body of the ultrasonic diagnostic apparatus itself needs to be newly processed. It was. However, in the present embodiment, if the change is slight, the type and the mounting position of the probe container 22 are changed, and even if there is a big change, only the rail member 20 needs to be newly processed. It can respond to changes easily.

  Furthermore, since the adapter 26 is appropriately interposed between the fixture 24 and the probe container 22, the direction of the slit 42 through which the probe cable passes can be adjusted to an easy-to-use direction. This will be described with reference to FIG. 8A is a top view when the probe holder is attached to the left side surface of the main body 12 of the ultrasonic diagnostic apparatus 10, and FIG. 8B is a top view when the probe holder is attached to the right side surface. FIG. 8C is a diagram showing an application example of the adapter.

  As shown in FIGS. 8 (A) and 8 (B), the slits 42 of the probe container 22 can be set to the near side by attaching the probe container 22 with the fixture 24 through the adapter 26 inclined in the forward direction. The probe can be easily placed on the probe container 22. That is, by interposing the adapter 26 having an inclined surface, the easy-to-use probe holder 16 can be easily realized regardless of whether the main body 12 is attached to the left side or the right side.

  Furthermore, if the shape of the adapter 26 is devised, not only the direction of the slit 42 but also the positional relationship between the probe container 22 and the rail member 20 can be freely adjusted. That is, for example, as shown in FIG. 8C, the inner side of the probe container 22a may be protruded to the side by using a rectangular adapter 26b having different thicknesses. By projecting toward the far side in this manner, the shapes of all the probe containers 22 can be recognized even when viewed from the front side of the ultrasonic diagnostic apparatus 10, and the probe holder 16 with higher operability can be easily realized.

  As described above, according to the present embodiment, a desired number and shape of probe containers can be fixed at a desired position for the user. Therefore, the operability of the ultrasonic diagnostic apparatus can be further improved.

  In this embodiment, the engagement hole and the lock pin are used as the engagement means between the rail member and the fixture, but other engagement means may be used as long as the fixture can be fixed at a predetermined position of the rail member. It may be. In addition, the fixture and the probe container, and the rail member and the main body of the ultrasonic diagnostic apparatus are all detachable by screwing, but may be connected by other means.
