Embodiment Construction

[0031] It should be noted that like numerals and letters refer to like items in the following figures, so once an item

[0037] a stent body 100 capable of being switched between a collapsed state and an expanded state;

[0038] and the actuator 200, the actuator 200 includes a conduit 210 and two drive members, the conduit 210 is used for threading

[0039] For the convenience of description, the two driving members may be the first driving member 220 and the second driving member 230, respectively.

[0044] Further, the first annular abutting portion 110 and the second annular abutting portion 130 of the stent body 100 are respectively used for

[0045] It should be understood that the stent body 100 may adopt a self-expanding structure, that is, when the stent body 100 is in a contracted state,

[0048] It should be understood that, in order to facilitate the switching of the stent body 100 from the unfolded state to the retracted state, the stent body 100 is set to

Abstract

The present application provides a stent system, including a stent body capable of switching between a contracted state and an expanded state; The driving parts are all connected with the catheter, and at least one of the two driving parts can slide relative to the catheter along the extending direction of the catheter, so as to drive the stent main body in the unfolded state to move when the two driving parts are relatively far away, so that the near The end and the distal end move away from each other and reduce the diameter of the stent body. The main body of the stent can be taken out from the blood vessel, the influence of the main body of the stent on the patient can be reduced, and the success rate of the operation can be improved.

Description

bracket system technical field [0001] The present invention relates to the field of medical equipment, in particular, to a stent system. Background technique [0002] At present, the drug stent is an important weapon against coronary thrombosis. The stent is implanted in the patient's body at the site of the thrombus, Eliminate thrombus and control regeneration by slow release of the drug. However, this operation has certain risks, and the stent will take a long time. Left in the human body, complete endothelialization takes 3-6 months. Before the stent is fully endothelialized, blood must contact the stent. It is easy to cause complications, so there is a certain risk, which is not conducive to the recovery of patients. Discovered through the inventor's research, existing drug stent has following shortcoming: [0004] Staying in the patient for a long time is not conducive to the recovery of the patient. SUMMARY OF THE INVENTION [0005] The object of the present...
