Position is adjusted, expected effect is not achieved.
Utility model content
Technical problem to be solved in the utility model is the defects of overcoming the prior art, provides a kind of band resetting work(
The stent delivery system of energy disclosure satisfy that stent needs to carry out stent releasing position tune after releasing a part in use
Whole needs.
The utility model solves technical solution used by prior art problem：A kind of stent with resetting function is defeated
Send system, including interior tube assembly, outer tube assembly and stent, the interior tube assembly include guiding soft head, middle pipe, inner tube, boost tube and
Inner tube handle, on inner pipe, said inner tube passes through boosting pipe orifice to the middle pipe suit, and said inner tube and boost tube are fixed on one
It is fitted into the hole of inner tube handle after rising, adjustment point and the first development point is fixed in said inner tube, said inner tube head end is fixed
Equipped with the second development point；The outer tube assembly includes outer tube, fixing pipe, locking cap and three-way connection, and the fixing pipe is inserted into inner tube
Hole in, which is inserted into from the big nose end of locking cap to aperture extreme direction, and the locking cap is sleeved on the point of inner tube handle
At end；The support casing is mounted in inner tube to the endface of middle pipe, and entire stent is slidably in outer tube is located at.
Further, the locking cap is fixed together and seals with inner tube handle.
Further, the soft headgear of guiding is mounted in the head end of inner tube.
Above-mentioned technical proposal is employed, the utility model has following advantageous effect：The utility model is simple in structure,
Multiple bearing or adjustment backing positions can be carried out when stent without discharging completely；The utility model sets double-developing point, can
It with multiple target shows where stent delivery system is in body cavities, convenient for observing and adjusting, discharges process in stent
In stent releasing position is accurately positioned and is adjusted, effectively improve the success rate of operation, reduce the difficulty and wind of operation
Danger, simple and safe operation are reliable.
