The present invention relates to encephalic crotch aneurysm holders, including rack body, occluding member, connecting rod and development point, rack body is reticular structure, occluding member is in flared, rack body is connect with occluding member by connecting rod, and development point is distributed in the distal end of the tail portion and the occluding member of rack body proximal end.Compared with prior art, the present invention preferably solves validity and the safety that treatment is improved for the aneurysmal closing of encephalic crotch.
Description
Technical field
The present invention relates to medical instruments fields, more particularly, to a kind of encephalic crotch aneurysm holder.
Background technology
Intracranial aneurysm is mostly the abnormal bulging being happened on entocranial artery tube wall, is the head for causing subarachnoid hemorrhage
The position cause of disease is only second to cerebral thrombus and hypertensive cerebral hemorrhage in cerebrovascular accident, occupies third.Any age can fall ill, most
It is apt to occur in 40 to 60 years old middle and aged womens.Cause the cause of disease of intracranial aneurysm still not very clear, most scholars think entocranial artery
Tumor is caused on the basis of the birth defects of entocranial artery tube wall part and cavity pressure increase, and hypertension, cerebral artery are hard
Change, vasculitis and aneurysmal generation are related with development.Treatment of intracranial aneurysm method is broadly divided into surgical clamp and closes at present
It is but high for suffering from aneurysmal patient's operation of opening cranium risk with intravascular Interventional Treatment technology, and along with multiple complications
Etc. factors, surgical clamp, which is closed, is not welcome by doctor.With the development of minimal invasive intravascular Interventional Treatment technology, more and more craniums
Internal aneurysm patient selects vascular interventional treatment, vascular interventional treatment technology to be increasingly becoming the main side for the treatment of intracranial aneurysm
Method.
The operation purpose of intravascular Interventional Treatment is：Using femoral artery puncture, very thin microtubular is positioned over artery
Tumor is intracapsular or tumor neck position, and soft titanium alloy spring circle is sent into aneurysmal sack and is full of using microtubular, is made
It obtains blood flow in aneurysmal sack to disappear, to eliminate the risk of rupture haemorrhage again.But to the aneurysm at aortic bifurcation
Speech, if aneurysm mouth cannot be closed well by being only implanted into common embolism holder, is easy to cause spring ring from aneurysm mouth
It leaks out, causes serious malpractice.At present for crotch aneurysm stenter to implant method be respectively be implanted into two holders into
Two Main Branches for entering blood vessel, could preferably carry out Coil embolization treatment, as shown in Figure 1, being divided into three steps：First
It is implanted into first holder 5, is then implanted into second holder 6 in infall, spring ring 7 is implanted into aneurysm finally by microtubular
Embolotherapy is carried out in 8.This operating method is complicated, wide to the coverage of blood vessel in operation, be easy to cause thrombus
With new embolic complications.
In conclusion being directed to the aneurysmal vascular interventional treatment technology of current encephalic crotch, there is an urgent need to develop one kind
It is used for the aneurysmal treatment of encephalic crotch using simple, efficient and safe holder.
Invention content
It is dynamic that it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of encephalic crotches
Arteries and veins tumor holder.
The purpose of the present invention can be achieved through the following technical solutions：
Encephalic crotch aneurysm holder, including rack body, occluding member, connecting rod and development point,
The rack body is the reticular structure of self-inflated,
The occluding member is in flared,
The rack body is connect with the occluding member by the connecting rod,
The development point is distributed in the distal end of the tail portion and the occluding member of rack body proximal end.
The rack body is the reticular structure that sine curve is constituted, and has better radial support power, holder is made to discharge
Position when preferably being discharged in blood vessel afterwards.The reticular structure of rack body is by cutting or working out.
The flaring angle of the occluding member is between 30 ° -179 °, to coordinate the aneurysm of different shape, bottom to be equipped with
The circular hole of a diameter of 1-3mm is connected with rack beams, prevents the spring ring in implantation aneurysm from leaking out, to preferably reach envelope
Close the purpose of aneurysm tumor mouth.
The connecting rod is equipped with four, to blood stream in two vascellum laterale of encephalic crotch when avoiding stenter to implant well
Dynamic influence.
The development point is hollow cylindrical structure.The development point by DSA technologies see holder release after in blood vessel
In state.
The preferably medical Super elastic alloy material of the material of the rack body, including metal tantalum, medical stainless steel and NiTi
Alloy etc..The occluding member is by cutting, the medical Super elastic alloy material of material selection, including metal tantalum, it is medical not
Become rusty steel and Nitinol etc..The materials such as the preferred platinum of the development point material, tantalum, tungsten.
The use process of the present invention：Holder is discharged first, the occluding member is implanted into aneurysm tumor intracavitary, by microtubular
By the circular hole of the occluding member bottom or the gap of circular, push rod makes spring by microtubular release spring circle
Circle is full of aneurysm cavity, recalls push rod and microtubular.
The holder of the present invention and micro-wire, microtubular, push rod etc. are used cooperatively, and are well known to those skilled in the art
The prior art.
Compared with prior art, the present invention has the following advantages：
(1) rack body structure uses sinusoidal self-inflated structure, has better radial support power, can be more preferable
Ground is adapted to blood vessel, will not occur sliding phenomenon in the blood vessels after holder discharges completely.
(2) stent occlusion part is to be fully inserted into aneurysm tumor chamber, and distal end is adapted in flared with aneurysm tumor mouth, can
It is leaked out with preventing from being implanted into aneurysmal spring ring well, preferably blocks tumor mouth.
(3) rack body is connected with occluding member by four bars, and not extra structure makes crotch aneurysm both sides
Blood can be with proper flow in blood vessel.
(4) circular hole of the occluding member bottom equipped with a diameter of 1-3mm is connected with rack beams, and microtubular is facilitated to convey spring
While circle, aneurysm tumor mouth is preferably closed.
(5) one or more development points are respectively set in the tail portion of rack body proximal end and occluding member distal portions,
After discharging holder, it can be very good to see the state after holder release in the blood vessel by technologies such as DSA.
