Abstract

PURPOSE:To secure a multi-conductor cable with a flexibility by securing an outer cover of the cable or a cover secured to the outer cover to a desired position in such a condition that a plurality of conductors and the cover covering the conductors are movable. CONSTITUTION:A rubber bushing 3 is adapted to reinforce the strength of a sheath 1-1 constituting a multi-conductor cable 1 which is secured to a probe 7 storing therein an ultrasonic probe. When the probe is moved on the surface of the body of the patient above his organism, the multi-conductor cable is bent. A difference DELTAL in displacement between the outermost peripheral part and the innermost peripheral part of the sheath caused by the bending of the cable is in proportion to the outer diameter D of conductors 1-2, and also to the bending angle theta. Accordingly, by applying a slight force overcoming the friction so that the cable which has been slacked in accordance with the difference DELTAL in displacement is paid out or taken up, the ultrasonic probe connected to the multi-conductor cable 1 may be moved freely on the surface of the body of a patient with a slight force in order to display an ultrasonic tomograph on a display surface, thereby it is possible to diagnose the patient.

Description

[Detailed Description of the Invention] [Summary] Regarding a multi-core cable fixing method for fixing a multi-core cable made by bundling a large number of core wires, the present invention aims to fix the multi-core cable with flexibility. The structure is such that the outer sheath or the covering fixed to the outer sheath is fixed at a desired location while the plurality of core wires and the outer sheath covering these a number of core wires are able to move freely. .

[Industrial application field]

The present invention relates to a multi-core cable fixing method for fixing a multi-core cable made by bundling a large number of core wires, and particularly relates to a multi-core cable fixing method for connecting a large number of signal lines to a probe case of an ultrasonic diagnostic device. It is.

(Conventional technology) The method used for connecting conventional multi-core cables is the fifth method.
The method shown in FIG. 5 uses a fixing metal fitting 23 from the outside of an outer sheath (hereinafter referred to as a sheath) 22-1 that gathers together and protects a plurality of core wires 22-2 constituting a multi-core cable 22. It is fixed to the cover 21. For this reason, each core wire 22-2 of the multicore cable 22 is firmly fixed by the fixing fitting 23 to such an extent that they cannot move relative to each other.

[Problem that the invention seeks to solve]

This conventional method shown in FIG. 5 allows the entire multicore cable 22 to be bent flexibly when the number of core wires 22-2 is small. By directly grasping the probe connected to the probe 22 and easily moving it freely over the patient's body surface, it is possible to display an ultrasonic tomographic image of internal organs on the screen.

For example, if the multicore cable 22 is about 48 or 64 elements, even if the multicore cable 22 is fixed using the method shown in FIG.
Flexibility against bending can be ensured.

However, in recent years, as the quality of ultrasound tomographic images has improved, the number of elements has increased dramatically to 128, 196, etc.
If the multi-core cable 22 is fixed in this way, there is a problem in that it loses its flexibility and becomes extremely difficult to use depending on the operating doctor.

An object of the present invention is to fix a multicore cable with flexibility.

[Means for solving problems]

Means for solving the problem will be explained with reference to FIG.

In Figure 1, 1. The multicore cable 1 has a sheath (outer covering).
) 1-1, it is composed of a plurality of core wires 1-2, and is intended to be fixed to the case 6.

The ring 2 is for fixing only the sheath 1-1 to the case 6.

The fixing fitting 4 is a fitting that fixes the sheath 1-1 to the case 6.

The fixing fitting 5 is a fitting that fixes the core wire 1-2 to the case 6.

[Effect]

As shown in FIG. 1, the present invention involves inserting a ring 2 inside a sheath 1-1 constituting a multicore cable l, and attaching a portion of the sheath 1-1 to a case 6 using a fixing fitting 4 from the outside. I am trying to fix it.

Moreover, the core wire 1-2 is given slack. Furthermore, the loose core wire 1-2 is attached to the case 6 using the fixing fitting 5.
I am trying to fix it to .

Therefore, since the sheath 1-1 constituting the multi-core cable 1 is firmly fixed to the case 6, the plurality of core wires 1-2 stored inside the sheath 1-1 can move freely, and the etc., it becomes possible to easily move the case (probe having an ultrasonic probe) 6 to which the multicore cable 1 is connected.

(Embodiment) Next, the configuration and operation of an embodiment of the present invention will be explained in detail using FIGS. 1 to 4.

In FIG. 1, a rubber bush 3 reinforces the strength of a sheath 1-1 that constitutes a multicore cable 1.

Using this configuration in Figure 1, as shown in Figure 2 (a),
When the multicore cable 1 is fixed to the probe 7, for example, the probe 7 storing an ultrasound probe connected to an ultrasound diagnostic device, and the probe 7 is moved over the body surface of the patient's organs, the corresponding Multicore cable 1 fixed to probe 7
is bent as shown in FIG. 2(b). Corresponding to this bending, the difference ΔL in displacement between the outermost circumferential portion and the innermost circumferential portion of the core wire 1-1 is expressed by the following formula i1+.

ΔL−〇(r+D/2)−〇(r−D/2)=Dθ・・
・・・ ・・・・・・・ ・[1] Here, 02 Angle r of the bent part: Curvature of multicore cable l ゛ To diameter D・Outside diameter of core vA1-2 As can be seen from this formula il+ , the difference in displacement ΔL between the outermost circumferential portion and the innermost circumferential portion of the core wire 1-1 is proportional to the outer diameter of the core wire 1-2 and proportional to the bending angle θ. According to this embodiment, the ring 2 is inserted inside the north 1-1 constituting the multicore cable l, and is firmly fixed to the case 6 using the fixing fitting 4 from the outside, so that the core wire 1-2 can be freely attached. Since it is placed in a movable state, the displacement difference ΔL according to the above formula (1)
Corresponding to this, it is sufficient to apply a force to overcome the slight friction so that the core wires 1-2, which have been loosened in the case 6, are fed out or pulled in. By this, a doctor or the like can remove the multi-core wires connected to the probe 7. By freely bending the cable 1 and moving the patient's body surface, it becomes possible to display a tomographic image at a desired position I.

Figure 3 shows how to fix the multi-core cable 1 with W+! ! ! North I-1 and multiple core wires 1- in the configuration shown in Figure 1.
2 shows a configuration in which the ring 2 inserted between the ring 2 and the ring 2 is omitted. This is done by widening the fitting part of the rubber dowel 3 with respect to the multicore cable 1 to increase the holding force due to FtX friction, and by fitting the rubber dowel 3 into the through hole of the case 6 to cover the sheath 1-1 of the multicore cable l. is fixed to the case 6. This allows the ring 2 in FIG. 1 to be omitted.

FIG. 4 shows a configuration in which the protection 5 coating 8 is fixed to the case 1-1 and the protective liquid J1!8 is fixed to the case 6 with an adhesive or the like. The ring 2 can be omitted, and the structure is more elegant than the rubber ring 3 shown in FIG.

〔Effect of the invention〕

As explained above, according to the present invention, the multicore cable l
Since the sheath 1-1 that constitutes the north 1-1 is firmly fixed to the case 6, the multiple core wires 1-2 stored inside the north 1-1 can move freely, and the multi-core cable l can be bent flexibly. This allows, for example, a doctor or the like to freely move the probe (probe with an ultrasound probe) 6 connected to the contact multicore cable 1 to the patient's body surface with a slight force and obtain an ultrasound tomographic image. It is possible to display the information on the screen and perform diagnosis.
