A system for implanting a membrane and a stent respectively, wherein the implanting system comprises:
- a body guide wire;
- a guide core, movably sleeved on the body guide wire;
- a catheter, for releasably holding a membrane, the catheter movably sleeved outside of the guide core;
- wherein the system for implanting the membrane is provided with an adjusting mechanism for adjusting an axial position of the membrane released by the catheter and the adjusting mechanism is detachably connected with the membrane,
- wherein the membrane comprises a body portion, formed into a tubular structure, and at least one branch portion, connected to the body portion, a branch guide wire passed into the branch portion,
- wherein the adjusting mechanism comprises a limiting knot arranged on the branch guide wire, and a limiting hole located in front of the limiting knot and formed in the branch portion, a size of the limiting knot larger than a size of the limiting hole;
- and
- a stent conveying device for releasably holding and conveying the stent,
- wherein the adjusting mechanism further comprises:
- a front end control wire, detachably connected to a front end of the body portion, and
- a turn transmission structure, turning the front end control wire that is extended backwards after a turn, wherein the turn transmission structure is a turn hole formed on a guide head;
- wherein the catheter and the guide core are extended backwards respectively, and the front end control wire, after being set out from the front end of the body portion and turned by the turn transmission structure arranged on the guide core, is passed through the guide core and is extended backwards;
- wherein the stent conveying device is sleeved on the guide core, the system further comprising:
- a guide core locking piece, for fixing the guide core relative to the catheter, which is fixedly connected with the catheter and is provided with a first locking portion and a second locking portion, both locked to the guide core in an unlockable manner respectively, and spaced apart from each other along an axial direction of the guide core;
- wherein the guide core locking piece has a first locking position and a second locking position, wherein
- at the first locking position, the first locking portion is in an unlock condition, the guide core is locked by the second locking portion in front of the first locking portion, the stent conveying device sleeved on the guide core is slidden between the first locking portion and the second locking portion along the guide core;
- and
- at the second locking position, the guide core is locked by the first locking portion, the second locking portion is in an unlock condition, and the stent conveying device is moved forward through the second locking portion.
