Description

  The present invention relates to an endoscope relay cable that connects an endoscope to a processor and other devices.

  An endoscope for diagnosing or inspecting an organ or the like by inserting an insertion portion into a body cavity includes an imaging means such as a CCD at its distal end, and operates the imaging means to obtain the obtained photoelectric device. It is connected to a processor that converts the converted signal into a video signal, or connected to a light source device for irradiating light from the distal end of the endoscope. Thus, a relay cable is used to connect the endoscope and a device such as a processor.

As a conventional example of a relay cable for an endoscope, a plurality of types of cables having different lengths are prepared and each device is connected by a cable arbitrarily selected from these cable groups. Yes. For example, an intermediate connector having an illumination plug is connected to the light source device (plug is inserted), and the other end of the cable having one end connected to the endoscope is connected to the intermediate connector, and one end of the signal cable is connected A device in which one side is connected to an intermediate connector and the other end side is connected to a processor is known (see Patent Document 1).
Japanese Utility Model Publication No. 3-35512 (first page, FIG. 1)

  When using an endoscope that is inserted into a body cavity, disinfect the relay cable including the relay cable after use to prevent nosocomial infection. For this purpose, as shown in FIG. 4, disinfection is performed after attaching a sealing device 100 for sealing the connectors 101 and 102 at both ends so that the disinfectant is not applied to the electrical contact portions provided inside the connectors at both ends. It was. This conventional relay cable 200 corresponds to “signal cable 8” described in Patent Document 1, for example. The sealing instrument 100 is obtained by connecting two seal plugs 100A and 100B with a chain 100C. In FIG. 4, the means for sealing is an example devised by the applicant of the present application, and is not known as a known example.

  Preparing a separate member for sealing and disinfecting the relay cable is time consuming and also costs the purchase of the separate member.

  It is an object of the present invention to provide an endoscope relay cable that can seal the electrical contact portions of the connector on both ends of the relay cable without preparing a separate member at the time of disinfection, and can simplify the disinfection procedure. .

  In order to achieve the above-described object, the present invention provides an endoscope relay cable for connecting an endoscope to a processor and other devices, wherein one end side connector of the relay cable is detachably connected to the endoscope. The other end side connector is also detachably connected to the other device, and both connectors on both end sides of the relay cable are connected to each other with a sealing property. Further, a socket part formed with a circumferential groove is provided on the outer peripheral side of one connector of the relay cable, and a plug part that fits into the circumferential groove of the socket part is provided on the outer peripheral side of the other connector side. The seal member is in close contact with the outer periphery of the plug portion when the socket portion is fitted.

  The present invention relates to an endoscope relay cable that connects an endoscope and a processor or other device. One end side connector of the relay cable is detachably connected to the endoscope, and the other end side connector is also connected to the other end. Since it is detachably connected to the device and the connectors on both ends of the relay cable are connected with a sealing property, no separate member for sealing is required, so the cost is not increased and the disinfection procedure is also performed. It can be simplified. Also, as a means for improving sealing performance, a socket portion having a circumferential groove formed on the outer peripheral side of one connector of the relay cable is provided, and a plug portion that fits in the circumferential groove of the socket portion on the outer peripheral side of the other connector side Since the seal member is in close contact with the outer periphery of the plug part when the socket part of the plug part is fitted, the structure becomes simple and the function of the electrical contact part is not impaired.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  In the embodiment shown in FIG. 1, the one end side connector 2 of the relay cable 1, for example, the endoscope side connector 2 and the other end side connector 3, for example, the processor side connector 3 are connected to each other in a sealable manner. It is what. The electrical contacts 2A and 3A are provided inside the connectors 2 and 3, and it is necessary to prevent the electrical contacts 2A and 3A from getting wet with the disinfecting liquid during disinfection. Therefore, in this embodiment, the socket part 5 in which the circumferential groove 4 is formed on the outer peripheral side of the processor side connector 3 is provided, and the circumferential groove 4 of the socket part 5 is provided on the outer peripheral side of the endoscope side connector 2. A plug portion 6 to be fitted is provided, and when the plug portion 6 is fitted to the socket portion 5, the seal member 7 is brought into close contact with the outer periphery of the plug portion 6. A seal member 8 is also provided between the outer cylinder portion 5 </ b> A of the socket portion 5 and the socket portion 5. Further, one or more projections 9 are formed on the outer periphery of the plug portion 6, and holes 10 corresponding to the projections 9 are formed in the socket portion 5. An L-shaped groove connected to the hole 10 is formed in the socket portion 5, and the protrusion 9 passes through the groove and rotates into the hole 10. Marks 11 and 12 are provided so that the state in which the protrusion 9 enters the hole 10 can be seen from the outside, and in this state, it can be confirmed that the connectors 2 and 3 are connected with a seal.

  In the embodiment shown in FIG. 2, the seal member 7 is provided on the socket part 5 side, whereas the embodiment shown in FIG. 1 provides the seal member 7 on the plug part 6 side. When the attachment / detachment frequency between the endoscope-side connector and the endoscope-side receiving member is high, the endoscope-side receiving member attaching / detaching force of the endoscope-side connector 2 can be reduced. Even in this embodiment, the attaching / detaching force can be reduced by preventing the sealing member 7 of the processor-side connector 3 from contacting the processor-side receiving member when the connector 3 is connected to the processor.

  FIG. 3 shows the entire relay cable 1 and shows a state in which the connectors 2 and 3 are connected to each other with sealing performance. As described above, the state in which the marks (circles) on the surfaces of the connectors 2 and 3 match each other indicates a state in which the protrusion 9 enters the hole 10 to achieve a sealing property and the connection is not removed.

The figure which shows the connection state of the partial cross section which shows embodiment of this invention. The figure which shows the connection state of the partial cross section which shows other embodiment. The whole front view which shows a connection state. The figure which shows a prior art example.
