Endoscope guide pipe

TL;DR: An endoscope guide pipe as mentioned in this paper is a pipe member with a first end, which is closed and in a generally convergent, rounded shape, and a second end which is opposite to the first end and open.

Abstract: An endoscope guide pipe includes a pipe member with a first end, which is closed and in a generally convergent, rounded shape, and a second end which is opposite to the first end and open. The pipe member is typically formed from a transparent material, such as a glass or plastic material. Thus, the guide pipe may be inserted into a body, and then an endoscope may be fitted into the guide pipe to observe the internal structure of the body. Since a defined space or cavity is maintained when the guide pipe is inserted into the body, so the internal structure of a body, such as a subcutaneous tissue, can be viewed directly by the endoscope in the present guide pipe. The guide pipe is particularly advantageous when it is desired to view directly a portion of a body which does not have a cavity or space, such as the internal structure of a muscle.
