Abstract

PURPOSE:To select respective kinds of switches without causing an operator in the middle of an observation to visually observe them by making respective kinds of switches provided to the hand operating part of an endoscope scope into external shapes to be recognized only with a touch feeling. CONSTITUTION:A hand operating part 2 of an endoscope scope 1 is equipped with an air feed/water feed push button two-stage switch 3, a suction switch 4 and a copy switch 5. For the external shape of the air feed/water feed push button two-stage switch 3, an upper surface shows the irregularity of a double concentric circle, and the upper surface of the suction switch 4 shows the irregularity of the flat circle of a central part and the concentric circle with a height lower than it. The upper surface of the copy switch 5 shows the irregularity of the double concentric circle having a central projection. Consequently, at the time of observing a body cavity internal part by introducing the introducing part of the endoscope scope 1 into the body cavity of a subject, the operator can recognize the necessary switch only by the touch of a finger.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is capable of observing the inside of a body cavity by introducing the guiding part of an endoscope into the body cavity of a subject. The present invention relates to endoscope devices, and particularly to improvements in the structure of various switches provided in the hand control section of an endoscope.

(Prior art) In recent years, endoscope devices have been equipped with a solid-state imaging device at the tip of an endoscope. An electronic endoscopic TI device that displays an observed image on a monitor based on a video signal obtained from an electrical signal has been proposed and put into practical use.

In this electronic endoscopy II device, the hand operation unit of the endoscope usually has an angle knob for bending the distal end of the scope, and a feeder for inputting input operations for cleaning the end face of the distal end of the scope. An air/water supply switch, a suction switch, a copy switch for performing an input operation for making a copy of a still image, and other switches are provided.

In this way, various switches are provided on the hand control unit of the endoscope, so conventionally, the user could visually identify the desired switch.
I color coded each switch.

(Problems to be Solved by the Invention) However, the condition for operating the various switches on the hand-operated unit of the endoscope is often when the operator is observing the inside of the body cavity of the subject.

For this reason, even if the various switches were color-coded for each switch, there were many situations in which it could not effectively contribute to identifying a desired switch from among the various switches.

The present invention has been made in view of the above problems, and its purpose is to allow an operator to inspect the inside of a subject's body cavity! To provide an endoscope device that allows a user to easily select a desired switch from among various switches on a hand-held operation part even during observation.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a hand control unit of an endoscope scope with the following features: The main point is to provide switches with various external shapes that can be used to

(Function) With the endoscope device according to the present invention, various switches such as the air supply/water supply push button two-stage switch, suction switch, copy switch, etc. can be used with just a sense of touch.
Therefore, even when the operator is observing the inside of the body cavity of the subject, the desired switch can be selected without visual inspection.

(Embodiment) FIG. 1 is a configuration diagram of a hand-operated unit of an endoscope, which is a main part of an endoscope apparatus according to an embodiment of the present invention.

The internal function II device of this embodiment is equipped with an air supply/water supply push button two-stage switch 3, a suction switch 4, and a copy switch 5 on the hand operation unit 2 of the endoscope 1.

When the air supply/water supply push button two-stage switch 3 is in the return state, pressing it once for the first time brings it into the air supply operation state, and then
One press of the button will bring the water supply operation state, and one more press of the button will bring it back to the return state, canceling the air/water supply operation.

The outer shape of the air/water supply push button two-stage switch 3 has a double concentric irregularity on its upper surface, as shown in the partially cut-away view of FIG. 2(A).

The suction switch 4 is in a suction operation state when pressed, and its external shape is a planar circle with the upper surface at the center and a height higher than this, as shown in the partially cutaway cross-sectional view of FIG. 2(B). exhibits low concentric irregularities.

When the copy switch 5 is pressed, it instructs to copy a still image, and its external shape is shown in Fig. 2 (C
As shown in the partially cutaway cross-sectional view of ), the upper surface exhibits double concentric irregularities with a central protrusion.

Furthermore, the upper part of the copy switch 5 has a gentle edge, whereas the other two switches, the air/water supply push button two-stage switch 3 and the suction switch 4, have a gentle upper part. The edges are almost rectangular.

The reason for this is that the air supply/water supply push button two-stage switch 3 and the suction switch 4 are used frequently and are used complementary to each other, whereas the copy switch 5 is used to copy still images during endoscopy. If it becomes necessary to take a picture, that is, the other two
These switches have different characteristics and are used less frequently.

In other words, even switches with different properties have different shapes.

The air supply/water supply push button two-stage switch 3, suction switch 4, and copy switch 5 are respectively coded in different colors.

° Therefore, when observing the inside of the body cavity by introducing the guiding part of the endoscope 1 (the part indicated by the reference numeral 6 in FIG. 3) into the body cavity of the subject, the operator can, for example, use only the touch of the finger. The copy switch 5 can be recognized.

In addition, in this embodiment, the various switches are coded in different colors, so that the switches can be recognized by color until the operator becomes skilled.

[Effects of the Invention] As explained above, the family celebration #lt device to which the present invention is applied is provided in the hand operation section of the endoscope scope, and allows various switches to be connected only by contact. Since the external shape is designed so that it can be recognized, the various switches described above can be selected without being visually inspected by the operator during observation.
