Description
Technical field
The present invention relates to a kind of Vascular haemostasis to block stent, belongs to medical instruments field.
Background technology
Heart is a most important organ in vertebrate body, and major function is to provide pressure for blood flow,
Blood operation is to body various pieces.Action of the heart is to promote blood flow, and sufficient blood flow is provided to organ, tissue,
To supply oxygen and various nutriments, and take away the end-product of metabolism（Such as carbon dioxide, inorganic salts, urea and uric acid）, make
Cell maintains normal metabolism and function.In cardiovascular injuries operation, often need to block a certain section of blood vessel, so as to
Position adjacent blood vessel is blocked to be operated to open.Existing blocking-up method is mainly hindered using aorta clamps
It is disconnected.But cardiovascular injuries operation usually needs longer operating time, if much time using aorta clamps presss from both sides for a long time
Tight sustainer carries out bloodstream blocking, and certain damage can be caused to aortic blood pipe outer wall.So will be by rule in surgical procedure
Fixed time interval unclamps aorta clamps, unclamps mouth in aorta clamps, sustainer has blood outflow, causes hand intraoperative blood loss
The increase of amount, adds operation risk.And it can pour in substantial amounts of blood after aorta clamps is unclamped, in operating field and block operation
Open country, is at this moment to need to carry out operation of sucking blood, cumbersome, extends operating time, further increases operation risk.
The content of the invention
In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide a kind of resistance of Vascular haemostasis
Disconnected stent, occluding catheter is inserted intravascular, blocks blood to obtain clearly surgical field of view by occluding catheter.Blocking is led
Pipe is inserted intravascular, and vascular wall will not be caused to damage.
In order to solve the above technical problems, the present invention adopts the technical scheme that, a kind of Vascular haemostasis blocks stent, including set
Pipe and internal filler plug, internal filler plug is socketed in casing and the outer wall of internal filler plug and the inner wall of internal filler plug are tight
