Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improved light source mounting unit built-in control that can be commonly used in endoscope bodies that are currently manufactured and sold by various manufacturers using their own methods and formats. It is related to the device.

As is well known, many improvements have been made in recent years, and one of the devices that has made remarkable progress is the endoscope, which is a medical device consisting of an endoscope body and its control device. By the way, the endoscope body for this endoscope configuration includes an operating section, also called a manual operating section, which is directly held by a medical practitioner to perform appropriate operations, and an operating section that is connected to this operating section and is connected to a body cavity. A flexible insertion part provided for insertion into the body, and a flexible insertion part that is also connected to the operation part and used for the medical treatment equipment part and its air/water supply, etc. ! r
It consists of a flexible cable that is used for connection to a control device containing a built-in rod control member.

The flexible cable has its exit end face facing the illumination window provided in the rigid part of the tip of the insertion section within the flexible jacket tube, and its entrance end face is installed internally within the control device. In addition to the optical fiber bundle for illumination (hereinafter referred to simply as the light guide), which is aligned with the condensing surface of the light source of the light source unit, air from the air supply pump, etc. in the control device is also connected to the tip of the light source unit. A flexible tube (hereinafter referred to as
(simply referred to as tubes, air supply tubes, or air and water supply tubes along with water supply tubes), and control members for solenoid valves such as air pumps, etc., for each operation provided in the operating section. The so-called rod-shaped sheath, which has lead wires, etc. for remote control using buttons, etc., drawn together and enclosed at the end, and has the incident end surface of the light guide at the tip, tube connection ports for various tubes, and various lead wires. The terminals, etc. of the cable are aligned and fixed at the end of this cable, and are configured as a so-called plug, which can be inserted and fixed into a socket provided in the control device, and these constitute a connecting part. .

This endoscope body is paired with a control device such as a built-in light source holder, and by sharing this, it becomes an endoscope suitable for the intended use, but this endoscope is not used as a medical device. , has been highly praised for its excellent functionality over the past few years,
It is considered indispensable, and its demand has grown rapidly, and its history of development is short, so it has not yet reached the stage of standardization.
Since there is not even a margin for this, each company and manufacturer has its own method or format, and it goes without saying that the above-mentioned connection parts, that is, the configuration of plugs and sockets, as well as air and water supply and suction. There were also considerable differences in their phylogenetic composition.

Therefore, when using an endoscope, if you use the endoscope main body and a control device such as a built-in light source holder dedicated to this endoscope main body, there will be no inconvenience, and you will be able to take advantage of its excellent features. Although it is functional, if it is not a dedicated control device, there are inconveniences such as the position of the condensing surface being different, and there are serious inconveniences and difficulties such as making it impossible to use in most cases. Therefore, each medical institution
Not only was it an economic disadvantage to have to install a separate endoscope body and dedicated control device for each purpose and place of use, but it was also necessary for medical practitioners to If the endoscope body is to be replaced and selectively used depending on the location of use, it is necessary to selectively replace the control device, such as the built-in light source mounting part, along with the endoscope body, which requires the surgeon to save extra time. It would not be an exaggeration to say that the current situation is fraught with the danger of causing a waste of means and time, and in some cases even causing serious consequences.

With the aim of eliminating these inconveniences and deficiencies, we have made it possible to use control devices such as the built-in endoscope body and light source mounting section, which previously could not be used as a pair. In order to provide a certain degree of compatibility, a method was developed to connect the endoscope body and a control device not exclusive to the endoscope body via an adapter, and in some cases it has been put into practical use. However, since the plug at the end of the connecting cable in the endoscope body is integrally equipped with a so-called rod-shaped sheath that introduces and contains a light guide, the adapter itself also has a light guide. The incident end face of this light guide is aligned with the condensing face of the light source unit which is equipped with a built-in control device that is not a dedicated machine, and its output end face is aligned with the incident end face of the light guide in the front iC cylindrical sheath. However, transmitting the illumination light through the light guide in this way suffers from a significant loss of light quantity and is far from achieving the intended purpose.

In view of the above-mentioned current situation, the present invention has been devised so that the light source unit, which has been installed almost fixedly in the control device, can be mounted movably along the front panel for forming the outer body of the control device. The front panel is equipped with different sockets into which plugs of different shapes with rod-shaped sheaths at the ends of flexible cables can be inserted and fixed in several types of endoscopic mirror bodies, as well as sockets inside the control device. The air supply tube from the air supply pump installed at the air supply pump is branched in the middle to form an air supply tube with a valve body that can be opened and closed by the movement of the light source unit, and is compatible with the plugs having the different configurations. The light source unit is connected to the air supply tube connection L of each of the different sockets, and the light source unit is moved for each endoscope body having plugs of different shapes to select the socket, and the conventional dedicated control is performed. This invention has made it possible to provide a built-in control device for an endoscope light device, which can be used without any inferiority to other devices, thereby completely eliminating the above-mentioned disadvantages. will be explained in detail with reference to illustrated embodiments.

That is, the endoscope light source mounting unit built-in control device X according to the present invention differs in its method and format, and can be used in endoscope bodies of different manufacturers with different shapes compared to the dedicated control device. It became possible to share the same information with no inferiority.

In addition, the reference numeral 14 in the above embodiment is a blower for cooling the end of the rod-shaped sheath, and the holding rod with the eldest child TO in the light source unit also serves as a support holder for one of the light source units. A member for moving the light source mounting part similar to the slider 30 with sliding holes may be provided in the front part of the light source unit, and other members may be designed and modified in various ways.

As is clear from the above description, the control device with a built-in light source device for an endoscope according to the present invention has a light condensing surface within the control device at a predetermined distance from the front panel for forming the outer shell of the control device. In addition to movably disposing the light source unit, an air pump is also installed, and the front panel has a rod-shaped sheath at the end of a flexible cable in several types of endoscope bodies. In addition to installing separate sockets into which different plugs can be inserted and fixed, the air supply tube from the air supply pump is branched in the middle, and valve bodies are respectively opened and closed by the movement of the light source unit. 4.1 The air supply tube is made to correspond to the plugs having the different shapes, and is connected to the air supply tube connection port of each of the different sockets, and the light source unit is moved, and the inner part having the plugs having the different shapes is connected to the air supply tube connection port of each of the sockets. The main feature of this system is that it can be connected to the endoscope body separately, and can be used with no inferiority to the control device dedicated to the endoscope body. By simply selecting a socket on the only control device placed in a predetermined position, it is possible to pair and use endoscopes of different shapes from different manufacturers. However, when using the endoscope itself, which is selected depending on the purpose and place of use, medical personnel are not forced to take extra measures and waste time as in the past, and they can also avoid the risk of triggers caused by this. This also eliminates the risk of being exposed.
