Problems solved by technology

[0006] However, the above-mentioned method has the problem that it is technically difficult to position the guide tube at the narrow part of the branch when it is implemented.
Not only that, the above-mentioned guide tube is separated from the stent insertion device during the operation, and in this case, it is necessary to recover the stent insertion device inserted into the body and fix the guide tube again, which is a serious waste of time and has the possibility of Problems that develop into medical malpractice

Abstract

A stent insertion apparatus comprising a guide member having a fixed part according to the present invention is a stent insertion apparatus comprising a guide member which is inserted into the body along a first guide wire inserted around the main area of stenosis to guide the movement of a first stent to be installed in the main area of stenosis, wherein the guide member comprises a fixed part, inserted into a branched area of stenosis branching from the main area of stenosis, for fixing the leading end of a guide tube into which a second guide wire, for installing a second stent that is to be installed in the branched area of stenosis, is inserted.

Description

technical field [0001] The present invention is a stent insertion device for installing a stent at a branch stenosis site other than the main stenosis site when a blood vessel in the human body is narrowed, and more specifically, it is a stent insertion device including a fixing part. A guide tube for installing the stent at the branch stenosis is fixed to a guide member that is inserted into the main stenosis and guides the installation position of the stent. Background technique [0002] Generally, when organs such as human blood vessels and esophagus that need to ensure a certain inner diameter are narrowed due to sediment, etc., a stent insertion device for inserting a stent is used to artificially expand the narrowed part. [0003] However, such a conventional stent insertion device has a problem that it is difficult to insert another stent into the branch stenosis when it is adjacent to a branch stenosis derived from the stenosis. Furthermore, when the cause of the st...
