Description
Technical field
The present invention relates 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 to enter in the patient.
Background technology
At present, along with the development of intervention apparatus, curing the disease that many surgical operations cannot be treated is cured.This
The treatment cured the disease a bit is relative to operating Therapeutic Method, and the wound of Cardiac catheterization method is little, recovers fast,
Curative effect is good.Through the most semicentennial development, Cardiac catheterization method has obtained swift and violent development, has also produced
Give birth to various interventional medical device product.Make more and more to cure the disease and patient obtains medical treatment.As,
Atrial septal defect plugging device, ventricular septal defect, patend ductus arteriosus occluder, patent foramen ovale block
Device, occluder for left auricle, vascular plug etc., can be placed into the diseased region of heart or blood vessel by conduit,
Reach the effect for the treatment of.
During Cardiac catheterization, typically in bending roundabout blood vessel, set up rail by tiny seal wire
Road, along the track of seal wire, is placed on induction system in human heart or artery and vein vascular.In induction system
Far-end arrive behind precalculated position, remove seal wire.Implant is imported in the conduit of induction system, utilize and push
The thrust of wirerope, is pushed to precalculated position by implant along the inner chamber of conduit.It is pushed out at implant and leads
During pipe end, this implant will be released in lesion locations, finally be dissociated with pushing wirerope by implant, remove
The assistive devices such as induction system, propelling movement wirerope, implant is retained in the internal effect playing treatment.
In above-mentioned operating process, particularly sheath core or implant are when pushed wirerope pushes internal, lead
The near-end haemostatic valve of pipe causes blood from overflowing owing to poorly sealed or gasket seal are torn, and also affects operation simultaneously
Period sucks air when inwardly carrying 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 used is designed with: 1, Rule open type；2, pad hemostasis valve type.
The conduit of Rule open type is, the near-end haemostatic valve at conduit is a public female Luer, inside has and conduit
The through hole of internal diameter, can place sheath core or implant by through hole.When there is no object or the least in through hole
Object time, blood can overflow in through hole.When implantation instrument, occupy owing to connecting the propelling movement wirerope of apparatus
A unique passage, it is impossible to connect syringe, the medicine needed for internal conveying therapeutic process.In order to solve
The problem of hemorrhage, people have been designed to gasket type haemostatic valve in the female Luer of catheter proximal end, and in haemostatic valve
Side one T-shaped or Y type interface of increase, connecting tee valve, can be to carry medicine in conductive pipe by three-way valve.
But during actually used, owing to pad is destroyed during sheath core and implant insert and extract out,
Pad is caused to deform, or at the wirerope of surface irregularity when by pad so that pad poorly sealed.
Cause patient's bleeding, result even in air suction and cause aeroembolism, crisis patient vitals in the patient.
Chinese patent CN103721341A discloses a kind of haemostatic valve device, by the way of pressing pressing means,
Make sealing member and otch open or close, thus stop the entrance of blood leakage or extraneous air, this hemostasis
Valve gear is only applicable to ductule, it is impossible to the openings of sizes of regulation sealing member.Chinese patent CN201643402U
Disclose a kind of rotary type haemostatic valve, by rotating rotary handle so that extrusion backs down or departs from silicone gasket,
When backing down, passage, equally this device can be set up and be only applicable to little conduit, be only capable of controlling opening and closing, it is impossible to do
Regulate to haemostatic valve openings of sizes.Chinese patent CN104800954A discloses a kind of adjustable valve catheter sheath, should
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 pressure
Block presses the second haemostatic valve, changes its openings of sizes.But the design structure of two haemostatic valve is more complicated, and the
Two haemostatic valve still can cause when big apparatus and conduit pass in and out leaking blood or causing gas entrance internal.
Therefore, the pluses and minuses of comprehensive various conduits, it is an object of the invention to develop a kind of haemostatic valve opening scalable
Conduit, blood from overflowing in use and gas can be avoided to enter in the patient, be also convenient for patient and exist
Inject medicine to patient when of needs, the effect of Catheter Interventional Therapy can be effectively improved, improve the safety of operation
Property and success rate.
Summary of the invention
In view of the defect of prior art, it is an object of the invention to provide a kind of interventional medical device induction system, special
It not a kind of adjustable conduit of haemostatic valve opening, be adapted to different conduits and sealing time apparatus passes through.
The haemostatic valve opening regulation of the conduit of the present invention is easy and simple to handle, can avoid blood from overflowing in use and
Gas enters in the patient, is also convenient for patient and injects medicine to patient needs when, can be effectively improved conduit
The effect of interventional therapy, improves safety and the success rate of operation.
