Abstract
Provided is a catheter operating structure in which a medical device such as a stent is rotated to move forward or backward without being repeatedly pushed or pulled when inserted into the lumen of a human body, so that a surgical position can be precisely adjusted by the forward or backward movement. A rotary member includes a spiral shaft formed on a handle so as to be inserted into a tubular body. A movable member includes a female spiral end that is formed at one end thereof and is spirally coupled with the spiral shaft. An injection member moving member moves together with the movable member. When the spiral shaft is rotated by rotation of the handle with the spiral shaft spirally coupled to the female spiral end, the movable member moves forward or backward without being rotated due to the injection member moving member.
