Abstract
Description
The present invention relates to an endoscopic inner stent.
Recently, in the intraperitoneal surgery, the incision is made in the abdomen rather than the abdomen and the endoscope is inserted into the abdomen or the endoscope is inserted through the opening in the body, have.
Accordingly, when inserting an endoscope for surgery, a device for guiding the path of the endoscope to move the endoscope to a target surgical position to the operation site is required. Prior art documents for such an apparatus include Korean Patent Laid- 2014-0037670 "(hereinafter referred to as " prior art ").
In this conventional technique, the distance between the endoscope and the tissue is guided by measuring the distance between the endoscope and the tissue based on the optical interferometer. The distance between the accurately calculated endoscope and the tissue reduces the tissue damage and the operation time .
However, the prior art is a device for guiding only the endoscopic movement in the lumen where the diameter is formed within a certain range in which the endoscope can move, and it is premised on the distance measurement in the space where the endoscope can move.
In addition, the practitioner directly confirms the distance between the endoscope and the tissue measured based on the optical interferometer. There has been a problem that the tissue is damaged due to unintentional contact that may be caused by hand shake of the operator or unexpected contraction and relaxation of the internal organs.
It is an object of the present invention to provide a method and apparatus for endoscopically moving an endoscope through a lumen formed by diameters different from each other in a body, To the user.
According to an aspect of the present invention, there is provided an endoscopic internal stent comprising: a first body portion having a hollow cylindrical shape; And a second body part having a hollow cylindrical shape with a diameter different from the diameter of the first body part at one end of the first body part.
Here, the first body portion may have different sizes of spaces formed by the crossing of the metal wires constituting the first body portion, and the first body portion may have flexural deformability.
The first body part may have a diameter larger than a diameter of the first body part at the other end of the first body part to prevent slipping of the first body part.
Here, the movement preventing portion is formed to have a larger diameter toward the direction of the end portion from the other end of the first body portion.
According to the present invention, the endoscopic inner stent is expanded and installed not only in the lumen of a diameter that facilitates the movement of the endoscope but also in the lumen of the diameter in which the endoscope can not be easily moved, the first body part and the second body part, , It is possible to secure a moving passage in the lumen which is difficult to enter the endoscope and to reduce the tissue damage due to the contact which may occur during the endoscope moving process.
