Depending on this, the treatment instrument raising table (not shown) is raised or
Or The other structure and operation and effect are the same as those of the sixth embodiment.
The description is omitted here. FIG. 14A is a longitudinal section of the cover of the insertion portion.
FIG. 14B is a cross-sectional view of the insertion portion cover, and FIG.
5 shows a state in which the cover endoscope is inserted into the insertion portion cover portion.
It is a longitudinal cross-sectional view. In this embodiment, the tendency of the endoscope to be inserted into the cover is described.
Improving the insertability of the endoscope with the top and cover into the body
You. The insertion portion cover 7 shown in FIGS.
Reference numeral 4 denotes a large lumen for inserting the cover endoscope 4.
75 and at least one (2 in the illustrated example)
) Has a hydraulic lumen 76. Fluid pressure room
Under normal conditions, part of the outer wall has a large lumen
A protrusion wall 80 protrudes inside 75. Said
In the vicinity of the distal end of the insertion portion cover 74, the fluid pressure lumen 7 is provided.
Injection holes 77, 7 communicating with 6, 76 and opening diagonally rearward
7 are provided. The fluid lumens 76, 76
A fluid supply device 79 is provided via a detachable connector 78, respectively.
It is connected to the. The fluid supply device 79 includes a fluid pressure loop.
Fluid is sent through the members 76, 76. The fluid supply device 7 is connected to the connector 78.
The 9 side is reused and the other side is disposable. Ma
Reference numerals 121 and 122 denote air supply pipes, water supply pipes, and reference numeral 1.
Reference numeral 23 denotes a channel provided with a treatment instrument raising table (not shown) at the end.
123. In the above configuration, the injection hole 77 is covered with a tape or the like.
By depressurizing the fluid pressure lumen 76 in that state,
Projection wall of fluid pressure lumen 76 projecting from large lumen 75
Since the surface 80 is dented and the large lumen 75 becomes large,
The endoscope 4 can be easily inserted, and after the insertion, the fluid pressure lumen 76 can be inserted.
When the pressure drop is released and the injection hole 77 is opened, the fluid pressure
The convex wall surface 80 of the housing 76 returns to its original position, and the endoscope 4 is
Rip. The fluid is then pumped through the fluid lumen 76.
If you spray from the spray hole 77, the endoscope with the cover 74 attached
The mirror 4 gains a forward propulsion force. Therefore, FIGS.
When inserting the cover type endoscope shown in
To make it easier to insert. [0089] According to the present invention, the mounting and removing of the raising operation member is performed.
Operation is easy, and the operability of raising the treatment instrument of a normal endoscope is impaired.
There is an effect of not doing.
