Background technique
In recent years, cardiovascular, cerebral vessels and peripheral blood vessel is narrow or the patient populations of embolism are continuously increased.Blood vessel is narrow
Narrow or embolism seriously affects people's lives and work, when serious or even threat to life.Netted branch is mainly applied in clinic at present
The products such as frame treat hemadostewnosis or embolic disease.These networks and its transportation system are both needed to pre- in the blood vessels before use
A filament is set, then network and its transportation system are set on filament, along filament track from vitro along intravascular space
Advance to hemadostewnosis or embolism position.Upon completion of the treatment, network and its transportation system are dropped back along filament track again
To external.For network when advancing along filament track or dropping back, diameter is smaller, in order to movement, but it is narrow in treatment blood vessel
When narrow or embolism, network needs enlarged diameter to squeeze blood vessel cavity wall.Along the advance of filament track or the accurate of position of dropping back
Property and enlarged diameter controllability be treatment success or not, or even influence patient's prognosis one of key.
Existing network and its transportation system lean on patient with feel when advancing along filament or dropping back in the market
It firmly pushes and pulls and adjust.This mode adjusted with patient's feel is by patient's individual difference, patient's mode of operation and use
Power size many uncertain factors such as uncontrollable influence, often not accurate enough to the location matches of network and lesion locations.
Existing network and its transportation system generally use external pressurizing device to the transportation system pressurising of network in the market,
Expand network diameter indirectly, or makes its enlarged diameter using the shape memory of network.The former expands netted branch
The mode of frame diameter is indirectly-acting, is affected by pressurizing device and transportation system；The side of the latter's expansion network diameter
Rule is passively to act on, and can only can not be adjusted according to disease event using shape memory adaptive into predetermined diameter.It can
See, the accuracy and expansion of network and its transportation system position when advancing along filament track or dropping back currently on the market
Equal less effective in terms of the controllability of diameter.
Therefore, the adjustment device for designing a filament control class medical instrument, realize use device regulation filament advance or
