Problems solved by technology

[0008] However, when electrical components are arranged in the operation unit, since the filling rate of the components arranged in the operation unit increases, the components in the operation unit may interfere with each other.
[0009] For example, when a solid or hollow soft member elongated along the insertion direction, such as a light guide or various tubes, is mixed with the bending drive mechanism in the operation part, the soft member interferes with the movable part of the bending drive part, Soft parts may break
In addition, when flexible components and electrical components are stored together with the bending drive mechanism, the flexible components and electrical components may interfere with the bending drive mechanism, which may hinder the operation of the bending drive mechanism.
[0010] Also, when the filling rate of the components installed in the operation unit increases, the components assembled in the operation unit at first become an obstacle, and it may be difficult to assemble the components assembled later.
[0011] Furthermore, since the electric components sometimes generate heat along with the driving, when the electric components are installed in the operation portion, the outer casing of the grip portion of the operation portion becomes hot, making it difficult for the operator to hold the grip portion for a long time.

no. 1 Embodiment approach

[0027] figure 1 It is a figure showing the endoscope of this 1st Embodiment, figure 2 It is enlarged to show that it is held by the operator's left hand figure 1 A diagram of the state of the operating part of the endoscope, image 3 From figure 2 III direction observation in figure 2 Diagram of the operating part of the endoscope, Figure 4 From image 3 Viewing in the IV direction image 3 Diagram of the operating part of the endoscope.

[0028] Such as figure 1 As shown, the endoscope 1 has an insertion part 2 to be inserted into the subject, an operation part 6 provided continuously at the proximal end of the insertion part 2 and held and operated by an operator, and a general purpose device extending from the operation part 6 . The cable 7 and the connector 8 provided at the extension end of the universal cable 7 constitute main parts.

[0029] In addition, the endoscope 1 can be freely connected to peripheral devices by freely connecting the connector 8 to a ...

no. 2 Embodiment approach

[0074] Figure 9 It is a cross-sectional view showing a structure in which an electrical component is fixed to a fixing plate so that the electrical substrate is parallel to the fixing plate in the endoscope according to the second embodiment.

[0075] The structure of the endoscope of the second embodiment is the same as that of the above-mentioned Figure 1 to Figure 7 Compared with the endoscope of the first embodiment shown, the difference is that the electrical components are fixed to the fixing plate so that the electrical substrate is parallel to the fixing plate. Therefore, the same reference numerals are assigned to the same configurations as those of the first embodiment, and description thereof will be omitted.

[0076] In the above-mentioned first embodiment, the case where the electrical component 50 is stored in the third storage area C located adjacent to both the first storage area A and the second storage area B, So that the first boundary line T1 between th...

no. 3 Embodiment approach

[0084] Figure 10 It is a cross-sectional view showing a structure in which a fixing plate and a shield case of an electrical component are integrally formed in the endoscope according to the third embodiment.

[0085] The structure of the endoscope of the third embodiment is the same as that of the above-mentioned Figure 9 Compared with the endoscope of the second embodiment shown, the difference is that Figure 10 The fixing plate is integrally formed with the shielding shell of the electrical component. Therefore, the same reference numerals are assigned to the same configurations as those of the second embodiment, and description thereof will be omitted.

[0086] In the second embodiment described above, the shield case 52 is fixed to the same surface of the fixing plate 80 as the surface on which the soft member 30 is fixed.

[0087] Not limited to this, such as Figure 10 As shown, similarly to the second embodiment, the third storage area C may also be located in t...

Abstract

The endoscope has a first storage area (A) provided in the operation part and containing the bending drive mechanism, a second storage area (B) provided in the operation part and containing the soft parts, a storage area (B) provided in the operation part and containing the electrical In the third storage area (C) of the components, in the orthogonal direction (Q), the first storage area (A) and the second storage area (B) are located side by side, and the third storage area (C) is located in the same position as Both the first storage area (A) and the second storage area (B) are adjacent to each other such that the first boundary line ( T1 ) is perpendicular to the second boundary line ( T2 ).

Description

technical field [0001] The present invention relates to an endoscope having an insertion portion to be inserted into a subject, and an operation portion that is continuously provided at a proximal end of the insertion portion in an insertion direction and is held and operated by an operator. Background technique [0002] In recent years, endoscopes have been widely used in the medical and industrial fields. The endoscope used in the medical field can observe the organs in the body cavity by inserting the elongated insertion part into the body cavity of the subject, and if necessary, use the Various treatments are performed through the treatment instrument inserted into the channel. [0003] In addition, the endoscope used in the industrial field can damage and corrode the inspected part in the inspected body by inserting the elongated insertion part of the endoscope into the inspected body such as jet engine or factory piping. and other observations or inspections of vario...
