[0037] For example, in the insertion tube assembly 1000 of the first embodiment of the present application, the tip body 10 is a hard tube. Of course, in other embodiments, the tip body 10 is a soft tube, and the present invention is not limited thereto.

[0038] like Figure 1-3 As shown, in the insertion tube assembly 1000 of the first embodiment of the present application, the pointed tip body 10 also has an intermediate tapered portion 12 and a rear end connecting portion 13. The intermediate tapered portion 12 is located between the front end extension portion 11 and the rear end connecting portion 13. The intermediate tapered portion 12 gradually becomes smaller backward along the front-to-back direction of the pointed tip body 10 to further facilitate insertion into a natural cavity or wound channel.

[0043] See also Figure 4-7 , is the insertion tube assembly 1000 ' of the second embodiment of the present application, which has the following differences relative to the insertion tube assembly 1000 of the first embodiment of the present application:

[0044] 1) In the insertion tube assembly 1000 ′ of the second embodiment of the present application, the tip body 10 does not have a middle tapered portion 12 and a rear end connecting portion 13;

[0045] 2) The front extension portion 11 is also bent in the direction of the camera channel hole 10a pointing to the instrument channel hole 10b, so that the front extension portion 11 can be more easily inserted into a smaller natural cavity or wound channel;

[0046] 3) The tip body 10 is a flexible tube, so as to achieve better movement in the natural cavity or wound channel by virtue of its deformability;

[0047] Except for the above-mentioned differences, the rest of the structure of the insertion tube assembly 1000' of the second embodiment of the present application is exactly the same as that of the insertion tube assembly 1000 of the first embodiment of the present application, so it will not be described here in detail.

[0048] Without being limited to the drawings, an embodiment of the present application provides an endoscope device, which includes the insertion tube assembly 1000 of the first embodiment of the present application or the insertion tube assembly 1000' of the second embodiment of the present application.

[0050] It should be noted that in the drawings, the direction pointed by the arrow Z is the front-to-back direction of the tip body 10, and the terms "front" and "rear" in this application are all referenced to the front-to-back direction of the tip body 10, but are not limited thereto.

[0051] The above disclosure is only a preferred example of the present application, and its role is to facilitate the technical personnel in this field to understand and implement it, but it cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made within the scope recorded in this application still fall within the scope covered by this application.
