Description
Technical field
This utility model relates to a kind of caval vein support, and specifically a kind of scalable caval vein mounting system, belongs to technical field of medical instruments.
Background technology
Angiostenosis is one of common disease medically, occurs in different parts and the organ of human body, existing heart and trunk, also comprises peripheral blood vessel (IVC stenosis, renal artery stenosis, iliac artery and femoral artery stenosis etc.).Cause the reason of angiostenosis a lot: as atherosclerosis, fibrillar muscle abnormal development, multiple arteritis, thrombosis etc.
Along with updating of angiostenosis lesions treatment technology, occurred a kind of emerging Clinics-interventional radiology, it has merged clinical skill, Medical Imaging Technology, electrophysiological technique etc. guide downcomer operation treatment brand-new subject at Imaging Method.Intervention diagnosis and therapy technology has become the three large treatment meanss of running neck and neck with internal medicine treatment, surgical operation.This technology (refers to puncture vessel by percutaneous catheter techniques, lesion is arrived along blood vessel by control lead in vitro, carry out a kind of means of Diagnosis and Treat disease) carry out the subject of medical diagnosis on disease and treatment, have fast effectively, wound is little, patient recovers fast feature.
The common operation plan of interventional therapy angiostenosis is divided into two large classes: blood saccule expansion and stenter to implant, because balloon expandable can only maintain the squeezing action of several minutes local, sacculus is withdrawn and be there will be elastical retraction by expansion place postcava afterwards, thus satisfied degrees of expansion cannot be reached, the latter's operating difficulty is relatively large but evident in efficacy.Therefore support is accurately located, is discharged most important, directly has influence on the success or failure of operation and the rehabilitation process of postoperative patient.
In interventional therapy IVC stenosis or seclusion, angiography can specify vascular lesion degree, scope, but largely depends on the experience of patient in support dispose procedure, and support is once release cannot adjust again.
Retrohepatic IVC is that cylindric diameter is about 2cm-3cm, and be connected with right atrium, RAD is greater than postcava diameter.The front jumping phenomenon of support is inevitably there is in self-inflated postcava support in the process pushing release, when support proximal part is close or part enters right atrium, because heart is quick, the contraction continued, the contraction that diastole campaign causes support passive and diastole, support within two months, can be caused because of metal fatigue to rupture and disintegrate, the support disintegrated can enter ventricle wall and pulmonary artery thus cause serious complication, support release is too low, effectively can not support lesion vessels, cause curative effect not good enough, releasing bracket makes hepatic vein opening part support reticular density increase again, increase the risk of hepatic venous obstruction.
Summary of the invention
For above-mentioned prior art Problems existing, this utility model provides a kind of scalable caval vein mounting system, while guaranteeing support support force, backing positions can be observed by radiography before support discharges completely, and release can be reorientated according to radiography situation recovery support, and front jumping effect when can eliminate self-expandable stent release, make backing positions more accurate, guarantee therapeutic effect, improve the safety of operation.
To achieve these goals, the technical solution adopted in the utility model is: a kind of scalable caval vein mounting system, comprises postcava support, connects wirerope, push rod and delivery sheath; Wherein, delivery sheath comprises inner core and trocar sheath, and postcava support is pre-installed in the conveying steel pipe of steel;
The supporting leg of described postcava support head end be connected the head end of wirerope for being threaded, connect wirerope tail end and be provided with and postcava stent helix freed discharge and provide the twisting controller of torsion, three forms a set of adjustable delivery system jointly;
Described push rod sidewall is provided with to be provided with the groove being connected wirerope diameter matches, afterbody and makes push rod, connects wirerope and the relatively-stationary adjustable bolt of postcava support.
The head end of described connection wirerope is female thread or external screw thread, and supporting leg and the head end of postcava support head end match.
Described connection wirerope length is 100cm-140cm.
Described push rod adopts politef to make, and length is 70cm-90cm.
Described delivery sheath diameter is 8F-12F, and end arranges haemostatic valve.
Described postcava support be self-expansion type support, by marmem adopt laser-engraving technique make, its hole is round and smooth large diamond hole, and main body is straight-tube shape.
The wire diameter of described postcava support is 0.3mm-0.4mm, main diameter is 26mm-32mm, length is 60mm-80mm.
Compared with existing postcava support, this utility model can observe backing positions by radiography before support does not discharge completely, if backing positions is unsatisfied with recoverable support, reorientate release, effectively eliminate front jumping effect when support discharges completely simultaneously, while lasting Ink vessel transfusing support force is provided, guarantee the accurate of support off-position, ensure that therapeutic effect, improve the safety of operation.
