Abstract
The invention relates to a catheter for arterial embolectomy. The catheter for arterial embolectomy is characterized by comprising a catheter provided with a balloon at a tip, a Luer port and a guide wire, wherein the balloon is made of a latex material and has elasticity, and the size of the balloon is expansible and retractable; an air inflation hole is formed in the middle of the tip of the catheter, and developing marks are arranged on two sides of the balloon of the catheter; and a guide wire cap is configured at the tail end of the guide wire. The catheter for arterial embolectomy is simple in structure and convenient to use, artery thrombus can be rapidly taken out, the vascular wall damage can be effectively reduced, and risks of artery perforation and plaque rupture can be reduced.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially a kind ofly get thrombosis conduit for Arterial system.
Background technology
Tremulous pulse is got bolt conduit and is had the features such as System Construction is simple, the simple and efficient practicality of clinical manipulation, can take out rapidly and simply the thrombosis in most patient tremulous pulse, do not need to introduce complicated machinery, be considered to be suitable for most the Interventional device of acute myocardial infarction; In use blood vessel wall is had to certain damage but existing tremulous pulse is got bolt conduit, have the probability of tremulous pulse perforation and plaque rupture.
Summary of the invention
For the deficiencies in the prior art, the invention provides one simple in structure, easy to use, both can go out arterial thrombus by fast fetching, can effectively reduce again the arterial blood extracting bolt conduit to vascular damaged.
For completing above-mentioned task, the technology of the present invention solution is achieved in that a kind of arterial blood extracting bolt conduit, it is characterized in that, comprise the most advanced and sophisticated conduit with sacculus, Rule port and seal wire, described sacculus is made up of latex material, there is elasticity, the inflatable contraction of volume; Described catheter tip middle part is provided with air-filled pore, on conduit, is provided with developing mark at sacculus two side positions; Described seal wire end is furnished with seal wire cap.
Described sacculus and conduit are sewed up fixing by epoxide resin material.
Described conduit is that pvc material is made, and catheter tip is connected with Rule port with the wing.
Described seal wire is the reinforcing steel wire of stainless steel material.
Before use, sacculus is full in the present invention, in contraction state, to ensure that conduit inserts blood vessel with minimum resistance; When operation starts, utilize seal wire not fill conduit and send to thrombosis place, sacculus section should exceed thrombosis place, subsequently, by Rule port, the solution after sterilization is filled with to sacculus, makes conduit have closely and contact with blood vessel wall, Balloon size can reach and intercept thrombosis effect, keep the full state of sacculus that conduit is softly withdrawn from, due to the iris action of sacculus, thrombosis also can move to last taking-up in the lump.Sacculus adheres to design and ensures the well-balanced geometric shape of sacculus, can have good contacting with blood vessel wall, thereby reduce the damage to blood vessel wall after filling, and sacculus profile softness, arc also can reduce the risk of tremulous pulse perforation and plaque rupture simultaneously.

Detailed description of the invention
A kind of arterial blood extracting bolt conduit, as shown in Figure 1, Figure 2 and Figure 3, is characterized in that, comprises the most advanced and sophisticated conduit 2 with sacculus 3, Rule port one and seal wire 7, and described sacculus 3 is made up of latex material, has elasticity, the inflatable contraction of volume; Described catheter tip 5 middle parts are provided with air-filled pore 4, on conduit, are provided with developing mark 6 at sacculus two side positions; Described seal wire 7 ends are furnished with seal wire cap 8; Described sacculus 3 is sewed up fixing with conduit 2 by epoxide resin material; Described conduit 2 is made for pvc material, and conduit 2 ends are connected with Rule port one with the wing; The reinforcing steel wire that described seal wire 7 is stainless steel material.
Embodiment 1, when the present invention is applied to femoral artery and far-end thrombosis removal surgery thereof, as shown in Figure 4, groin incision appears strand total, strand shallow a, deep femoral artery, walks around respectively rubber strap, and first moderate is tightened up but incomplete blocking blood flow; On femoral artery,common, do the longitudinal incision that a length is 1～1.5cm, then utilize seal wire that not Filled Balloon of the present invention and conduit are inserted to femoral artery,superficial or deep femoral artery, conduit is inserted to far-end as far as possible, sacculus section need exceed thrombosis place, then the capacity of indicating by tube wall on the other hand makes sacculus full to sacculus saline injection, another hands is pressed conduit and pulls out gradually conduit at body surface, and thrombosis can take out from tremulous pulse cutting section.
Embodiment 2, when the present invention is applied to Jing popliteal artery thrombectomy, in knee joint inner incision Xian Lu popliteal tremulous pulse and bifurcated thereof, walks around respectively picture belt, and Qie Kai popliteal tremulous pulse inserts the present invention, after being inserted to far-end, inject a little normal saline upwards pull-out, thrombosis can take out in incision.
Embodiment 3, the present invention is applied in the time of bilateral femoral arterial abdominal aortic bifurcation place thrombosis removal surgery, in bilateral groin incision, appears bilateral femoral artery,common, free 5～6cm, every side is walked around respectively twice rubber strap; First, with not damaged blocking-up pincers blocking-up right common femoral artery, tighten up two rubber straps of left side femoral artery, between twice, cut the osculum that a length is 1～1.5cm, upwards insert arterial blood extracting bolt conduit, to the above level of bifurcated, slowly pull-out after water filling in sacculus, removal of thromboses; Then take out opposite side thrombosis with same method.
