预装载支架输送系统
By designing a pre-loaded stent delivery system and utilizing the sliding connection between the pusher and the stent tip, the stent can be safely released at the vascular lesion site. This solves the problem of stent tip damage to blood vessels in existing technologies, improves operational safety, and simplifies the release process.

AI Technical Summary
In existing stent delivery systems, the tip of the push rod or inner sheath can easily damage the inner wall of the blood vessel during deployment, increasing the complexity and difficulty of the operation and limiting the choice of deployment location.
A preloaded stent delivery system was designed, including a pusher, a head end, an inner tube, and an outer tube. The stent is loaded between the outer tube and the inner tube. The head end is slidably connected to the inner tube. After the pusher drives the stent and the head end to move to their extreme positions, the stent is released from the gap between the head end and the outer tube. The head end is located inside the stent to avoid the head end crossing the lesion site.
This reduces the risk of irritation and damage to blood vessels at the stent tip during stent deployment, simplifies the procedure, and improves the safety and reliability of the surgery.
