Abstract
The utility model relates to a releaser for an intracavity stent. The releaser delivers and releases the stent into a blood vessel lumen of a human body and belongs to the field of medical devices. The main structure of the releaser comprises a release wire and a duct assembly. The releaser for the intracavity stent has following beneficial effects: the support is delivered to a targeted artery by a simple and reliable mode; the length of the releaser is suitable for surgical operation; an artery blood vessel is prevented from being damaged by the releaser; the possible operation difficulty caused by lowering the releaser is avoided; safety and reliability of treatment are enhanced; and the releaser is especially suitable for repairing an branch artery of arcus aortae in an artificial blood vessel of arcus aortae replacement operation by an interventional method and is safe and reliable to use.
Description
Technical field
This utility model relates to a kind of releasing device of support being sent into and is released to human vas intracavity, belongs to medical apparatus and instruments.
Background technology
At present, for the pathological changes that occurs in human blood circulatory system, for example hemangioma or arteriorrhexis, can adopt the method getting involved in tube chamber to treat.The basic skills of interventional therapy is in patient's blood vessel outside, by operation induction system, support in blood-vessel to be sent to vascular lesion position to treat.The development of interventional therapy can substitute operative treatment to a great extent, makes Operative risk reduce simultaneously.Suitable induction system is depended in the successful implementation of interventional therapy.Basic demand to induction system is: support can be loaded and sends to predetermined position in tube chamber, support can be stablized and discharge exactly and induction system is convenient to exit.Current stent delivery system is to take simple interventional therapy as object substantially, and for the interventional therapy carrying out in surgery combination (hybrid) operation, current existing induction system structure is too complicated, and length is also not suitable for using in operation.Obviously, stent delivery system need to further develop, to meet the demand of stent applications.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of support that is applicable to use in surgical operation and sends into and releasing device.
The intracavity stent release that this utility model is designed, primary structure, for discharging silk and conduit tube component, discharges silk and walks through conduit tube component.
In this utility model, one end of conduit tube component is termination, and the other end, for discharging silk outlet, has the grab handle through conduit between the two ends of conduit, and conduit external diameter is between 0.6mm-1.8mm.
In this utility model, discharge silk gripping shank position row in catheter lumen, between grab handle and catheter end head, pass conduit, be parallel to conduit outer wall, at position, termination, penetrate termination.
In this utility model, discharge filament diameter between 0.2mm-1.0mm, there is pull handle the one end that discharges silk.
In this utility model, the spacing between grab handle and catheter end head is between 2cm-26cm.
This utility model is when application, identical with the ultimate principle of existing general conveyer device, is also that the standoff conveyer device of loading is delivered to expection therapentic part releasing bracket.Different, of the present utility modelly send into simple in structurely, send into suitable length, meet operation user demand.
The advantage of the intracavity stent release that this utility model is designed is:
1. simple in structure, conduit tube component and release silk complete to be carried and release function, is convenient to operate in surgical operation;
2. release length is mated with stent length, is convenient to implement the combination hands art of surgery and intervention;
3. release diameter is applicable to the interventional therapy of the above different bore tremulous pulsies of medium-sized artery.
The designed intracavity stent release of this utility model is applicable to the interventional therapy in tremulous pulse surgery combination operation, for example, in aortic arch artificial blood vessel valve replacement, adopt interventional method reparation bow portion bifurcated artery.
Accompanying drawing explanation
Accompanying drawing 1 is that the schematic diagram of the designed intracavity stent release of this utility model: 1-discharges silk, 2-conduit, and 3-catheter end head, 4-grab handle, 5-discharges silk pull handle.
The specific embodiment
1 in conjunction with specific embodiments structure and the embodiment of the designed intracavity stent release of this utility model are described further with reference to the accompanying drawings below.
Intracavity stent release as shown in Figure 1, the diameter that discharges silk 1 is 0.2mm, it navigates within conduit 2 intracavity at grab handle 4 positions, conduit 2 external diameters are 1.5mm, discharge silk 1 and between catheter end head 3 and grab handle 4, be parallel to conduit 2 outer walls, 3 positions penetrate termination 3 in termination to discharge silk 1, and the spacing between catheter end head 3 and grab handle 4 is 6cm, and discharging silk 1 has pull handle 5 at the other end that penetrates termination 3.During application, support is loaded between grab handle 4 and catheter end head 3, by pushing grab handle 4, affined support is sent into target arterial, fixedly grab handle 4, by discharging silk pull handle 5, release silk 1 pulled out, and support is expanded voluntarily, be supported in lumen of artery, release exits.
This utility model is sent support into target arterial by simple, reliable mode, the length of release is suitable for operating in surgical procedures, avoid damage that release may cause arteries, reduce the operating difficulties that release may cause, improve the safety and reliability for the treatment of, be particularly suitable in aortic arch artificial blood vessel valve replacement, adopt interventional method reparation bow portion bifurcated artery, safe and reliable.
Above-described embodiment is that concrete scheme of the present utility model is given an example, and protection domain is limit according to claim.
Claims (5)
1. an intracavity stent release, primary structure, for discharging silk and conduit tube component, is characterized in that: discharge silk and walk through conduit tube component.
2. intracavity stent release according to claim 1, is further characterized in that: one end of conduit tube component is termination, and the other end, for discharging silk outlet, has the grab handle through conduit between the two ends of conduit, and conduit diameter is between 0.6mm-1.8mm.
