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 configuring this endoscope is connected to an operating section, which is also called a nine-hand edge operating section, which a medical practitioner can directly hold and perform appropriate operations. A flexible insertion part used for insertion into the body cavity, and a control unit that is also connected to the operation part and has built-in control parts for each building, such as the light source unit and its air and water supply. It consists of a flexible cable used for connection with equipment.

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
Various control members such as tubes, air supply tubes, and water supply tubes (also called air supply and water supply tubes together with water supply tubes), and solenoid valves such as air supply pumps are controlled by various operation buttons provided on the operation unit. Lead wires, etc. for remote control are drawn together and enclosed in a so-called rod-shaped sheath whose tip is the incident end surface of the light guide, tube connection ports of 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 device, and by sharing this, it becomes an endoscope suitable for the purpose of use, but this endoscope can be used as a medical device. Its excellent functionality has been highly praised over the past few years,
As an indispensable item, the demand for it has grown rapidly, and its history of development is short, so it has not yet reached the stage of standardization, or there is not even room for it. Since each company and manufacturer has its own method or format, it goes without saying that the connection part, that is, the configuration of the plug and socket, as well as the air supply, water supply, suction system, etc. There were also considerable differences in the composition of the two.

Therefore, when using an endoscope, if you use the endoscope body and a control device such as a built-in light source unit dedicated to this endoscope body, there will be no inconvenience and no problem. Although it exhibits excellent functionality, if it is not a dedicated control device, there are inconveniences such as the light converging surface being different.
Because there are serious inconveniences and drawbacks, such as the fact that it cannot be used in most cases, each medical institution chooses a manufacturer that is suitable for its purpose and place of use. Not only was there an economic disadvantage in having to install the endoscope body and its own control device, but medical practitioners were also forced to replace the endoscope body depending on the purpose and place of use. In such cases, it is necessary to selectively replace the endoscope body as well as the control device such as the built-in light device, which results in extra measures and wasted time for the medical practitioner, and can sometimes lead to serious consequences. It is no exaggeration to say that there is a danger that this could lead to

In order to eliminate these inconveniences and deficiencies, we have made it possible to use control devices such as the endoscope body and built-in light source unit, which until now could not be used as a pair. In order to provide 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 come into practical use. However, as mentioned above, the plug at the end of the connecting cable in the endoscope body is integrally equipped with a so-called rod-shaped body that incorporates a light guide, so the adapter itself also incorporates a light guide. The incident end surface of this light guide is made to coincide with the light condensing surface of the light source unit that is equipped with a built-in control device that is not a dedicated machine.
The ice is configured such that its output end face faces the input end face of the light guide in the rod-shaped sheath, and transmitting illumination light through the light guide in this way may result in a severe loss of light quantity or the intended result. He could not escape the accusation that he was far from achieving his goal.

In view of the above-mentioned current situation, the present invention makes it possible to move the light source unit, which has heretofore been almost fixedly installed inside the control device, along the front panel for forming the outer shell of the control device. and the front panel is provided with different sockets into which plugs of different shapes each having a rod-like sheath at the end of a flexible cable of several types of endoscope bodies can be inserted and fixed; The light source unit movably mounted in the control device is moved to a position corresponding to a sockt in which plugs of the endoscope main body having plugs of different shapes can be inserted and fixed, respectively. When the corresponding plugs are inserted into the sockets, the rod-like sheaths of those plugs are inserted into the insertion holes, which prevents the light source unit from moving accidentally and makes it different from the conventional dedicated control device. This makes it possible to provide a control device built into an endoscope light device, which can be used without any inferiority, and thereby eliminates all the above-mentioned disadvantages. This will be explained in detail using examples.
