Problems solved by technology

[0011] However, although in the structure of the endoscope system disclosed in Japanese Patent Application Laid-Open No. 5-329097, the driving part is indeed arranged outside the endoscope, but since the endoscope is provided in the light source device, It is difficult to disassemble the light source unit of the illumination light, and it is also difficult to take out the driving parts, so there is a problem that it is difficult to replace

no. 1 Embodiment approach

[0038] figure 1 It is a perspective view schematically showing the endoscope system of this embodiment.

[0039] Such as figure 1 As shown, the endoscope system 100 has an endoscope 1 inserted into the subject, a display device 10 as an external device having a light source device 11 and a display processor 12, a monitor 13, and a control device for the external device. 15, constitute the main part.

[0040] An endoscope 1 has an insertion part 2 that is elongated along an insertion direction S to be inserted into a subject, an operation part 3 connected to a base end of the insertion part 2 , and an extension end extending from the operation part 3 with a The universal cable 4 of the connector 5 connected to the light source device 11 constitutes a main part.

[0041] On the front end side in the insertion direction S of the insertion part 2 (hereinafter simply referred to as the front end side), there is provided a bending part 2w as a functional part, and the bending par...

no. 2 Embodiment approach

[0095] Figure 7 is a perspective view schematically showing the endoscope system of this embodiment, Figure 8 is schematically shown only to extract the Figure 7 Partial cross-sectional view of the structure for electrically driving the bending part in the endoscope and a part of the drive cable, Figure 9 is only schematically shown Figure 7 A block diagram of the structure for electrically driving the bending part in the endoscope system of .

[0096] The configuration of the endoscope system of the second embodiment is the same as that described above Figure 1 ~ Figure 3 The endoscope system of the first embodiment shown is different in that the wire that bends the bending portion is not wound around a pulley, but is wound around a C-shaped wire that can come into contact with the outer periphery of the pulley in a frictional manner. On the ring, and connected with the operation part.

[0097] Therefore, only the points of difference will be described, and the sam...

no. 3 Embodiment approach

[0128] Figure 12 is a perspective view schematically showing the endoscope system of this embodiment, Figure 13 is showing Figure 12 A diagram of part of a rotating self-propelled endoscope, Figure 14 is schematically shown only to extract the Figure 12 Partial cross-sectional view of the structure for electrically driving the bending part in the endoscope and a part of the drive cable, Figure 15 is only schematically shown Figure 12 A block diagram of the structure for electrically driving the bending part in the endoscope system of .

[0129] The configuration of the endoscope system according to the third embodiment is the same as that described above. Figure 1 ~ Figure 3 The endoscope system of the first embodiment shown, Figure 7 ~ Figure 9 The endoscope system of the second embodiment shown is different in that the electrically driven functional part is the turning part of the rotary self-propelled endoscope.

[0130] Therefore, only the difference will b...

Abstract

The endoscope system has: an endoscope (1), which is inserted into a subject; a bending part (2w), which is provided in the endoscope (1) and is electrically driven; a control device (15), which outputs Control signal, the control signal is used to control the drive bending part (2w); and the drive cable (20), which is detachable with respect to the endoscope (1) and the control device (15), and, according to the control device ( 15) Driven by an output control signal, it has a motor (21) inside that applies a driving force to the bending portion (2w) via a flexible shaft (30).

Description

technical field [0001] The present invention relates to an endoscope system including an endoscope inserted into a subject, an electrically driven functional unit provided in the endoscope, and a control device for controlling driving of the functional unit. Background technique [0002] In recent years, endoscopes having an insertion portion inserted into a subject have been widely used in the medical and industrial fields. [0003] Endoscopes 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 treatment instrument inserted into the endoscope to penetrate The treatment instrument inserted into the channel performs various treatments. [0004] In addition, the endoscope used in the industrial field can damage and repair the parts to be inspected in the object by inserting the elongated insertion part of the endoscope into the object to be inspected, such ...
