Description
Technical field
The present invention relates to medical instruments field, especially a kind of dismountable treating cardio-cerebral vascular disease holder device.
Background technique
Cardiovascular and cerebrovascular disease and arterial hemangioma seriously threaten the mankind, give patient's bring to mitigate traditional open surgery
Pain or reduction open cranium, open the risk of the major surgeries such as chest, have used the methods of intervention operation installation cardiac stent and blood vessel
Tumor bracket etc..
Currently, the intracorporal cardiac stent of implantation people, hemangioma bracket etc. are once convey in place, strutting cannot be again after installing
It takes out；Meanwhile in the blood vessel after mounting bracket, to prevent from being formed thrombus or rejection, patient also needs to take anticoagulant medicine always
Object also brings no small side effect to human body.For acute cardiovascular and cerebrovascular disease, after mounting bracket, by drug etc. into
Row treatment, acute stage, go over, after the completion of bracket effect, can not use bracket, but current bracket cannot be dismantled, and also need one
Directly take the drug of maintenance bracket；For being mounted with hemangioma bracket or filling the patient of hemangioma spring ring, with hemangioma
Variation, need to be adjusted or striking substantially can not.
Summary of the invention
In order to overcome the shortcomings of existing medical treatment implantation holder device, the present invention provides a kind of dismountable treating cardio-cerebral vascular disease
Holder device.
The technical solution adopted by the present invention to solve the technical problems is: a kind of dismountable treating cardio-cerebral vascular disease branch is rack-mounted
It sets, including support body, the support body is that the reticular structure made of using magnetic carbon nano-tube material is constituted.
It is further preferred that the surface of support body is equipped with biocompatible coating.Realize the good blood of support body itself
Compatibility and antisepsis, and the durability used is improved, the blood compatibility coating of surface setting meets insertion type Medical treatment device
The surface related request of tool.
Preferably, the shape of a mesh of support body reticular structure is diamond shape, which is convenient for producing under the action of external magnetic field
Raw deformation and sizing.
Preferably, the shape of a mesh of support body reticular structure is hexagon, stretches and shrinks under external magnetic fields
Stable network can all be formed.
Preferably, the support body in a tubular form, the supporting role that can be played stably in the blood vessel.
This support body is that the reticular structure made of using magnetic carbon nano-tube material is constituted, and carbon nano-tube material itself has
There is good toughness, can stretch, support body is due to being to be better than magnetic carbon nano-tube magnetism with magnetic reticular structure
Deformation can be generated under the action of external magnetic field.Apply one respectively at the both ends of support body and is better than the outer of magnetic carbon nano-tube magnetism
Portion magnetic field, two magnetic fields are mobile to the separate opposite direction in both ends respectively, in itself magnetic of the magnetic carbon nano-tube with support body
Property phase separation, for guide support body reticular structure to both ends cross directional stretch, support body forms elongated shape, and external magnetic field is removed
Afterwards, since neighbouring two sides of reticular structure are after, elongated shape is maintained by the magnetism of itself.Elongated shape
Support body syringe needle punctures in injection patient vessel, by applying introduction by magnetic field in vitro, is moved to designated position in the blood vessel,
It can also be transmitted in place by the guide wire of traditional intervention operation.After reaching designated position, applies be better than magnetic outside the patient's body
Property carbon nano-tube magnetic two magnetic fields, two external magnetic fields the both ends of the support body of elongated shape simultaneously to center position transport
It is dynamic, in the magnetic phase separation of the magnetic carbon nano-tube of the support body with elongated shape, guide the netted knot of the support body of elongated shape
Structure cross-direction shrinkage, longitudinal dilatation form the bracket shape for matching and adapting to blood vessel.After external magnetic field is removed, due to a netted left side
For right two adjacent edges close to together, magnetic by magnetic carbon nano-tube itself maintains bracket shape.
After the completion of bracket effect, when needing to remove recycling support body, outside the patient's body, in the support body of bracket shape
Both ends apply the external magnetic field for being better than magnetic carbon nano-tube magnetism respectively, and two external magnetic fields are respectively to the side far from both ends
To movement, in itself magnetic phase separation of the magnetic carbon nano-tube material with support body, the reticular structure of guide support body is to two
End stretches, and the support body of elongated shape is formed, after external magnetic field is removed, since two sides up and down of diamond-mesh are tightly attached to one
It rises, maintains elongated shape by the magnetism of itself.Then, the support body of elongated shape draws in such a way that external magnetic field guides
It leads and punctures opening taking-up in blood vessel designated position syringe needle, can also be ticked by the guide wire of traditional intervention operation.
The invention has the advantages that support body is made of innovative magnetic carbon nano-tube material, support body is net
Shape structure, carbon nano-tube material itself have good toughness, can stretch, and are being better than support body material magnetic field carbon nano tube magnetic
Property external magnetic field effect under, the stretching and contraction distortion of horizontal and vertical both direction can be achieved at the same time in support body, solves
The technical problem that cardiovascular and cerebrovascular bracket is dismantled after the completion of effect.
The material that support body uses is magnetic carbon nano-tube, and support body reticular structure mesh is diamond shape, is being better than support body
Under the external magnetic field effect of material magnetic field carbon nano-tube magnetic, support body is stretchable and contraction distortion, support body reticular structure
After the left and right of diamond-mesh or neighbouring side are close to each other, after external magnetic field is removed, under magnetic carbon nano-tube magnetic action,
Support body can keep stable shaped.
The mesh of support body reticular structure uses hexagon, and can stretch and shrink under external magnetic fields can all form
Stable network.
After mounting bracket, medicine is passed through for acute cardiovascular and cerebrovascular disease by the support body that magnetic carbon nano-tube constructs
Object etc. is treated, and acute stage goes over, after the completion of bracket effect, can not use bracket, also there is no need to take maintenance again
The drug of bracket；It, can be with angiomatous variation for being mounted with hemangioma bracket or filling the patient of hemangioma spring ring
The problem of being according to circumstances adjusted or striking, better solving hemangioma rupture.
