Description

[Detailed explanation of the idea] The present invention relates to an endoscope connection structure.

Endoscopes used in medicine and industry have light guides, air/water supply pipes,
Tube bodies such as suction pipes and other electrical cords are extending, but conventionally these tube bodies have been combined into one tube with one plug 1 at the tip as shown in Fig. 1, or as shown in Fig. 2. As shown, a single light guide 2 is made independent in the middle of its extension from the handle, and a plug 3 is attached to the tip of the light guide, so that it can be inserted as necessary into a plug 5 provided at the tip of the other integrated cladding tube 4. However, these plugs are incompatible because they are designed to only fit into the connection point of a specific control device that has a built-in compressed air source, suction pump, power source, light source, etc. The endoscope and control device cannot be used unless they are paired together.

However, if the endoscope and control device are specified as a pair in this way, it is not possible to replace just the endoscope when you want to select and use an endoscope that is suitable for the observation area, and the endoscope is large and Certain control devices must be replaced or purchased and installed, and as a result, selective use of the endoscope is not actually possible.

The purpose of the present invention is to solve the above-mentioned drawbacks, and by manufacturing various types of unit plugs suitable for the connection points of various control devices, the light guide led out from the endoscope handle, each feed tube, A feature is that the suction tube, electric cord, etc. are detachably connected to the unit plug, so that the desired endoscope can be connected to any control device by selecting the unit plug. shall be.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is an overall side view showing an embodiment of the present invention, in which 6 is an endoscope body, 7 is a flexible tube, 8 is a handle to which the flexible tube 7 is connected, and 9 is a tube body. , the number of tube bodies varies depending on the purpose of use of the endoscope body 6,
It is generally made up of the following tube bodies. These are light guides, air supply pipes, water supply pipes, suction pipes, electrical cords, etc., and these are either combined into one or multiple cables, or each is led out from the handle 8 independently. Each tip is a connecting end 9a that can be connected to a unit plug to be described later.

FIG. 3 shows an example of the unit plug 10. One side is a connected port 10a that can be connected to the connecting end 9a of the tube body 9, and the other side and the peripheral surface are compressed if necessary. A connecting portion 10b is formed that can be connected to a connecting point of a control device (not shown) that includes an air source, a suction pump, a power source, a light source, and the like.

In other words, since the connection points of each control device are of different types, in order to fit the respective connection points, the connection points of the unit plug are connected in addition to the above connections on the side and circumference as shown in Figure 4. Various types of unit plugs with different shapes are provided.

Note that the above-mentioned tube body is an example, and for example, in the case of an endoscope without an electric cord, there is no connection port and connection portion for the electric cord, as shown in FIG.

According to such a configuration, one side has the connection end 9a of the tube body 9 led out from the handle 8 of the endoscope as the connectable port 10a, and the other side has the connection end 9a connected to the connection point of each control device. By preparing multiple types of unit plugs with connecting portions 10b that match the connection points of various control devices, an easily portable endoscope can be attached to any control device. It becomes possible to use it.

Normally, each company has one type of control device for one type of endoscope, so unit plugs are manufactured as many as the number of control devices from each company and matched to the control device the user owns. You can select it.

Note that each unit plug may be marked with a mark or the like so that the combination with each control device can be easily identified.

According to the present invention having the above configuration and operation, 1
One side is a connection port that can be connected to the connection end of the tube led out from the handle of the endoscope, and the other side is a connection port that can be connected to a control device, which is a connection point for various types of control devices. By manufacturing multiple unit plugs for each type of control device and selecting and using the unit plug that matches each control device, the endoscope can be used with any control device. It is possible to select and use an endoscope that suits the purpose of use, and there is also an advantage that there is no need to move or replace a heavy and large control device.
