Description

[Detailed Description of the Invention] This invention relates to a cable holder that holds the cable of an ultrasound probe used in, for example, an ultrasound diagnostic apparatus.

Generally, in the case of an electronic scanning type ultrasound diagnostic device, a desired tomographic image is obtained by bringing an ultrasound probe (hereinafter simply referred to as a probe) connected to the device body via a cable into contact with the subject. The operator then moves the probe to another examination position to obtain a tomographic image. Conventionally, cable support devices used in such devices include those shown in FIG. That is,
A holder 2 is attached to the upper end of the column 1, a mounting hole 3b is provided in the middle of the column 1, and a cable holder 3 made of an elastic material is attached to the through hole 3.
It is inserted through a. The support device has its base end rotatably attached to an arm holder provided on the main body of the ultrasonic diagnostic apparatus or a dedicated cart (not shown), and a cable 5 having a contact 4 at one end is connected to the tip of the support 1. The cable holder 3 is held by a holder 2 provided at
It is configured to be inserted through the notch 3c and held in the holding hole 3b. In recent years, ultrasonic diagnostic apparatuses are often adapted to different diagnostic sites and uses by simply replacing the probe 4 with the cable 5. However, when the probe 4 with the cable 5 is replaced with another one, the thickness of the cable 5 may differ depending on the probe 4, or the number of cables may be multiple, and each time the probe 4 is replaced, Cable holder 3 also had to be replaced. That is, if the thickness of the cable 5 is smaller than the diameter of the holding hole 3b of the cable holder 3, the cable 5 may not be held sufficiently, and the cable may move in the vertical direction.
Further, there is a drawback that the cable may fall out of the holding hole of the cable holder.

This invention was developed based on the above circumstances, and it can securely hold cables even when the cables have different diameters, can hold multiple cables, has an extremely simple configuration, and is reliable. The object of the present invention is to provide a cable holder that can be supplied as a high quality product at low cost.

This invention will be explained with reference to an embodiment shown in the drawings.

Fig. 2 is a plan view showing an embodiment of the cable holder of this invention, Fig. 3 is a plan view showing a state in which a large diameter cable is held, and Fig. 4 is a plan view showing a state in which a small diameter cable is held. It is. In each figure, 10 is a cable holder, and this cable holder 10 is made of an elastic material such as rubber, and has a through hole 12 for mounting at one end of a main body 11 formed in an oval shape. , this through hole 12
is inserted into a support column (not shown), for example. On the other hand, a pair of holding holes 13A and 13B having different diameters are bored in parallel at the other end of the main body 11 (in the figure, the holding hole 13B has a larger diameter). The pair of holding holes 13A and 13B have notches 14A and 14B formed on opposite outer edges (left and right side edges in the figure), respectively, and a notch in the large diameter holding hole 13B (on the right side in the figure). The recessed portion 14B has one small-diameter holding hole 13A so that both pieces 15B and 15B' are normally separated from each other.
Both pieces 15A, 15A' are configured to abut each other. Further, the notch 14B has a gap such that both pieces 15B and 15B' come into contact when a small diameter cable is held in the small diameter holding hole 13A. The shape of the pair of holding holes 13A, 13B is normally circular in shape, but is not limited to this, and may have an appropriate shape depending on the cable of the device to be used. It is something that can be done. Further, the width of the notch 14B is determined as appropriate depending on the size of the holding hole 13B.

Next, the state in which a cable having a probe at one end is attached to the cable holder 10 will be explained.
The cable holder 10 is supported by inserting the through hole 12 of the cable holder 10 into the middle part of a column (not shown) made of an elastic thermoplastic resin such as polypropylene. Note that this support is rotatably held by an arm holder provided on the main body of the ultrasonic diagnostic apparatus or a dedicated trolley. When holding a large-diameter cable 16A as shown in FIG.
The cable 16A is inserted through the two pieces 15B and 15B' of B at an appropriate position and is held in the holding hole 13B by the elastic force of the main body 11. At this time, when the holding hole cable 16A is about to come off due to a force applied from the outside, a force acts on the pieces 15B and 15A to move counterclockwise, but the holding hole 1
Since both pieces 15A and 15A' of the notch 14A of 3A are in contact with each other, a clockwise reaction force acts on the pieces 15B and 15A, making it difficult for the holding piece 15B to open counterclockwise. Therefore, the cable 16A can be firmly held.

On the other hand, as shown in FIG.
When holding B, the holding hole 13A will be used. In other words, the small-diameter cable 16B is inserted into both pieces 1 of the notch 14A of the holding hole 13A at an appropriate location.
5A, 15A', the pieces 15A, 15A' of the notch 14A are separated by the elastic force of the main body 11, and the pieces 15B, 15A' of the notch 14B of the holding hole 13B are inserted.
15B' comes into contact. At this time, when the cable 16B is about to come off due to a force applied from the outside, a force is applied to the pieces 15B and 15A to move clockwise, as in the case shown in FIG. Both pieces 15B, 15 of notch part 14B of 13B
Since B' is in contact with each other, a counterclockwise reaction force acts on the pieces 15B and 15A, making it difficult to open the holding hole 15A in the counterclockwise direction. Therefore, cable 16B
can be held firmly. Also, the holding hole 13
The small diameter cable 16B inserted into the main body 1
It will be held by an elastic force of 1. Also,
Even if the diameter of the small diameter cable 16B is slightly larger than the diameter of the holding hole 13A,
The cable holder 10 can be held by both pieces 15A, 15A' of the notch 14B, and the elastic force of the main body 11 ensures the holding, and even cables with slightly different diameters can be held without replacing the cable holder 10. be able to. In addition, two cables 16A with different diameters are attached to the cable holder 10,
16B can also be inserted into the holding holes 13A and 13B and held at the same time in the same manner as described above.

FIG. 5 is a plan view showing another embodiment of the cable holder of this invention, in which the diameters of the pair of holding holes 13A, 13B are formed to be approximately the same size, the notches 14A, Both pieces 15A, 15 of 14B
It differs from the previous embodiment in that A', 15B, and 15B' are formed so as to be separated from each other, and other points are almost the same as those of the previous embodiment, so a detailed explanation of the configuration will be omitted. That's it.

It should be noted that the above embodiment is merely an example, and it goes without saying that each member can be replaced with another member having the same function. For example, it goes without saying that the shape of the main body 11 is not limited to an elliptical shape, but can be made into an appropriate shape depending on the device used.

Since this invention is constructed as described above, it is possible to reliably hold multiple cables at the same time or when the diameter of the holding hole is different from the diameter of the cable.
It can be used as is even when replacing the probe. Furthermore, the structure is extremely simple, and it has excellent effects such as being able to supply a highly reliable product at a low cost.
