Description
Technical field
The utility model is related to a kind of interventional medical device induction system, including the adjustable conduit of haemostatic valve opening, can
To avoid blood from overflowing in use and gas from entering in patient's body.
Background technology
At present, with the development of intervention apparatus, what many surgical operations cannot be treated cure the disease is cured.These are cured the disease
Treatment relative to surgical operation treatment method, the wound of Cardiac catheterization method is little, recovers fast, and curative effect is good.Through inciting somebody to action
The development of nearly half a century, Cardiac catheterization method has obtained swift and violent development, also generates various intervention medical treatment
Device product.So that more and more cure the disease being obtained medical treatment with patient.Such as, atrial septal defect plugging device, ventricular septal defect closure
Device, patend ductus arteriosus occluder, oval hole plugging device, occluder for left auricle, vascular plug etc., can be put by conduit
The diseased region of heart or blood vessel is put, the effect for the treatment of is reached.
During Cardiac catheterization, typically track is set up in roundabout blood vessel is bent by tiny seal wire,
Along the track of seal wire, induction system is placed in human heart or artery and vein vascular.Reach pre- in the distal end of induction system
Positioning is postponed, and removes seal wire.Implant is imported in the conduit of induction system, using the thrust for pushing wirerope, will be implanted into
Body is pushed to precalculated position along the inner chamber of conduit.When implant is pushed out catheter tip, the implant will be released in disease
Become position, finally implant dissociates with wirerope is pushed, remove induction system, push the assistive devices such as wirerope, implant is stayed
Put the effect for playing treatment in vivo.
In above-mentioned operating process, particularly sheath core or implant when pushed wirerope pushes internal, conduit
Near-end haemostatic valve causes blood from overflowing because poorly sealed or gasket seal is torn, while also affecting inwardly to be conveyed during operation
Air is sucked during medicine.This can cause patient's massive blood loss, and What is more can cause aeroembolism, jeopardize patient vitals.
Generally, what the near-end haemostatic valve of conduit was adopted is designed with：1st, Rule open type；2nd, pad hemostasis valve type.
The conduit of Rule open type is, is a public female Luer in the near-end haemostatic valve of conduit, inside has and catheter diameter
Through hole, sheath core or implant can be placed by through hole.When object without object or only little in through hole, blood
Can overflow from through hole.In implantation instrument, because the push wirerope for connecting apparatus occupies a unique passage, it is impossible to connect
Syringe, the medicine to needed for conveying therapeutic process in vivo.In order to solve the problems, such as hemorrhage, people connect in Rule of catheter proximal end
Head has been designed to gasket type haemostatic valve, and increases a T-shaped or Y type interface, connecting tee valve, by three in the side of haemostatic valve
Port valve can convey medicine into conduit.But during actually used, due to pad sheath core and implant insertion and
During extraction be destroyed, cause pad to deform, or surface irregularity wirerope by pad when so that pad
It is poorly sealed.Patient's bleeding is caused, resulting even in air suction patient's body causes aeroembolism, crisis patient vitals.
Chinese patent CN103721341A discloses a kind of hemostasis valve gear, by way of pressing pressing means so that close
Sealing and otch are opened or closed, and so as to prevent the entrance of blood leakage or extraneous air, the hemostasis valve gear is only applicable to
Ductule, it is impossible to adjust the openings of sizes of seal.Chinese patent CN201643402U discloses a kind of rotary type haemostatic valve, leads to
Overwinding turns rotary handle so that extrusion backs down or depart from silicone gasket, when backing down, can set up passage, and the same device is only
Suitable for little conduit, control opening and closing is only capable of, it is impossible to accomplish that haemostatic valve openings of sizes is adjusted.Chinese patent CN104800954A is public
A kind of adjustable valve catheter sheath is opened, the device has double-deck haemostatic valve, and the first haemostatic valve has " one " word tangent line, and the second haemostatic valve has
Through hole, by gland cap the second haemostatic valve is pressed, and changes its openings of sizes.But the design structure of two haemostatic valves is more complicated, and
Second haemostatic valve can still cause to leak blood when passing in and out or cause gas to enter in vivo in big apparatus and conduit.
Therefore, the pluses and minuses of comprehensive various conduits, the purpose of this utility model is that a kind of haemostatic valve opening of development can adjust
Conduit, blood from overflowing in use and gas can be avoided to enter in patient's body, be also convenient for patient need when
Wait and inject medicine to patient, the effect of Catheter Interventional Therapy can be effectively improved, improve the security and success rate of operation.
