Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Application Field) The present invention connects a plurality of connecting wires wired between an apparatus main body and an endoscope tool using a connector. The present invention relates to a separable endoscope device, and particularly to improvements in the structure of a connector section.

(Prior Art) Conventionally, this type of endoscopic device has been equipped with various bonding wires for supplying light, water, air, etc. from the device body to the endoscope. A connector that can be grafted onto a connector receiving portion provided on the casing surface of the endoscope was provided at the end of the so-called universal cord of the endoscope, which was a cord made by bundling the above-mentioned bonded wires.

However, the above-mentioned connector of the conventional structure was manufactured from the viewpoint that it would be sufficient if the connector was firmly fitted to the connector receiving portion of the main body of the device, and various problems occurred.

(Problem to be Solved by the Invention) In other words, in the case of a conventional endoscope device of this type, the connector of the endoscope scope is fitted into the connector receptacle tJ portion of the device main body, and the IW is possible. Sometimes an endoscope]
- Due to the Nll nature of the universal cord of the endoscope, it was difficult to operate the endoscope, and problems occurred such as the universal cord of the endoscope being twisted when operating the endoscope.

14. In recent years, there have been remarkable technological advances in electronic endoscope-based endoscope devices and imaging devices, and in this case, the number of wiring has increased as the control system has become more complex. .

Therefore, within this species? 11 When the latest electronic endoscopy and imaging methods are applied to the gastroscope, the number of wires increases dramatically, and the rigidity of the universal cord of the endoscope increases. It is assumed that the reaction force due to the torsion of is also increasing.

If the conventional connector connecting/disconnecting structure is adopted when the reaction force due to the rigidity and twisting of the universal cord increases as described above, it will become extremely difficult to operate the endoscope, impairing its practicality.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to ensure that even if the number of connecting wires wired between the device body and the endoscope is increased,
It is an object of the present invention to provide an endoscope device that allows easy mirror operation and prevents twisting of a universal cord.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention connects a plurality of connecting wires wired between the device body and the endoscope using a connector. In the separable endoscope device, a connector receiving portion for the connector is provided on the casing surface of the device main body, and at least one of the plurality of bonding wires is provided at an interconnection point between the connector and the connector receiving portion. a first connection mechanism having an ``11'' structure that connects and separates the
The second connection is configured to be rotatably separated around the connection mechanism, and has a structure for connecting and separating a plurality of bond wires other than the bond wires that are connected and separated by the first connection mechanism. The gist is to do so.

(Function) With the endoscope device according to the present invention, even when the latest electronic endoscopy method or imaging method is applied, the connecting line (Δ is the end of the light guide) that is brought into contact and separated by the first connection mechanism. A light guide plug mounted in the part is equipped with a connecting wire that should avoid bending stress as much as possible, and a large number of electric signal wires and tubes for air supply, water supply, etc. are connected and separated by the second connection mechanism. Since the second connection mechanism is rotatable with respect to the first connection mechanism, the rigidity of the universal cord formed by bundling the above-mentioned bonded wires is reduced when operating the endoscope. , and the problem of twisting the universal code itself is avoided.

Therefore, even if the number of joining wires increases, the operation of the endoscope is easy, and the universal cord can always be held well.

(Embodiment) FIG. 1 is a perspective view showing a main part and its surroundings of an endoscope apparatus according to an embodiment to which the present invention is applied.

The endoscope device of this embodiment has an endoscope in the device main body 1.
-12 is used by attaching the endoscope]-12
A plurality of connecting wires, such as a light guide, various electric signal lines, air supply, and water supply, are wired between the device main body 1 and the endoscope 2 by the connector 4 mounted on the end of the universal cord 3. It is possible to connect and separate tubes such as

That is, the connector 4 is mounted on the end of the universal cord 3, which is formed by bundling and disposing the plurality of connecting wires, and the terminals of each connection 1i1 of this universal cord 3 are formed. .

In particular, the light guide plug 5 mounted on the 9-way portion of the light guide (not shown) is connected to the connector 40 as shown in FIG.
A group of terminals 6 of a plurality of other bonded wires protruding toward the side
and has been placed for a minute.

On the other hand, in order to fit the connector 4 and connect and separate the plurality of connecting wires between the device main body 1 and the endoscope 2, the connector receiving portion 7 is attached to the housing surface 8 of the device main body 1. Set up as shown in Figure 3.

In the connector receiving part 7 itself, each continuous terminal is arranged so as to correspond to the terminal arrangement of the connector 4, and
As shown in FIGS. 3 and 4, each of the connecting terminals is composed of a light guide chuck 9 and a terminal holder 10 having a valve head configured to be rotatable about the guide chuck 9 to the lie 1. ing. In this embodiment, a cutout groove 11 is provided coaxially with the light guide chuck in the connector receiving portion 7 in order to guide the movement of the terminal holder 10.
is formed.

Connector 4 and connector receiving portion 7 configured as described above
In this mutually fitted state, the connector 4 is rotatable about the coupling position between the light guide plug 5 and the light guide chuck 9. Note that the rotation range of this connector 4 is restricted by the notch groove 11.

Therefore, according to an embodiment of the present invention, even if the number of connecting wires wired between the device main body 1 and the endoscope scope 2 is significantly increased, a universal wire can be used when operating the endoscope. Since it is not affected by the rigidity of the cord 3, the operation of the endoscope is much easier than in the past.

In addition, since the universal cord 3 is prevented from twisting and twisting when operating the endoscope, each of the multiple bonded wires is well protected, and since twisting is prevented, the reaction force due to twisting is reduced when operating the endoscope. This avoids a situation in which the endoscope 2 is sometimes exposed to the endoscope.

[Effects of the Invention] As explained above, the internal mirror device N to which the present invention is applied
Even if the number of connecting wires installed between the device body and the endoscope is significantly increased,
Since the connector part is configured to be freely rotatable, it is easy to operate the endoscope, and the unipartial cord consisting of a large number of connecting wires is prevented from twisting during operation of the endoscope. .
