Abstract
The utility model relates to the technical field of medical instruments, and relates to an intracoronary foreign matter catching device which removes metal foreign matters in a coronary artery such as fall-off of a guide wire, support deloading or the like due to coronary artery interventional diagnosis and treatment surgeries. The intracoronary foreign matter catching device comprises a catching lantern ring and a lead-in pipe, the catching lantern ring is made of metal wires such as Ni-Ti-shaped memory alloy wires, stainless steel wires or other good elastic metal wires, and comprises a catching rod (1) and a lantern ring (2). The lead-in pipe is a slender catheter of good flexibility, the internal diameter of the lead-in pipe is fit with the external diameter of the catching rod (1), a front end of the lead-in pipe is provided with an HDPE/ platinum iridium mark ring (3), a tail end of the lead-in pipe is provided with a bell mouth (4), and the catching lantern ring is inserted into the lead-in pipe via the bell mouth. The intracoronary foreign matter catching device is advantaged by simple structure, low cost, and convenient usage, and the foreign matter in the coronary artery can be safely and effectively removed.
Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of foreign body catching device in the arteria coronaria that the seal wire that produces due to arteria coronaria intervention diagnosis and therapy art in coronary artery comes off, support takes off metallic foreign bodies such as carrying of removing.
Background technology
The arteria coronaria interventional technique is the important method of coronary heart disease diagnosis and treatment, have Wicresoft, patient's misery little, recover fast, determined curative effect, the plurality of advantages such as need not transfuse blood.But in the coronary intervention process, conduit appears sometimes, the seal wire distortion comes off after fractureing, support takes off and carries, and metallic foreign body is trapped in arteria coronaria and produces complication.Although this class complication rate is very low, in case occur, may cause fatal consequence, as vascular endothelial injury, thrombosis etc.Because arteria coronaria is thinner, diameter is only 2-4 mm, therefore there is no desirable way for the processing that the arteria coronaria inner guide wire comes off, support takes off foreign bodies such as carrying, mainly contain at present 4 kinds of methods: 1) two seal wire winding technologies, utilize respectively take off carry support inside and outside two wire distals be wound in knot, support is retracted in the arteria coronaria guiding catheter.Handling poor, the length consuming time of this kind method operation, x-ray light exposure are large, and success rate is low, the easy damaged distal vessels, and be not suitable for the crawl of other foreign bodies except support.2) sending into new support is expressed to foreign body on blood vessel wall.Although this method success rate is high, foreign body is permanent in vivo residual, has potential thrombosis, arteria coronaria aneurysm, the inaccessible equivalent risk of arteria coronaria subbranch.3) cardiac bioptomes gripping art, but biopsy forceps is expensive, the not conventional outfit of most hospitals, and in operating process patient's lack of experience, easily injured blood vessel endothelium.4) surgical operation takes out foreign body in arteria coronaria by opening breast, and this kind method wound is large, complication is many, and expense is high, should be the alternative approach of last consideration.Above-mentioned the whole bag of tricks respectively has deficiency, can not be satisfied with by the clinician.
Summary of the invention
The purpose of this utility model is to provide foreign body catching device in a kind of easy and simple to handle, safe and effective, economical and practical arteria coronaria.
This utility model is by arresting the collar and ingress pipe forms, the said collar of arresting is made by the tinsel of niti-shaped memorial alloy silk, stainless steel silk or other good springiness, minute collar and arrest bar two parts is arrested bar and mutually is entwined by the B alloy wire of collar both sides; Said ingress pipe is the good slender conduit of a pliability, it is made by the good macromolecular material of histocompatibility, as macromolecular materials such as polyethylene, nylon and polyamide, the internal diameter of ingress pipe and the external diameter coupling of arresting bar, ingress pipe is used for arresting the collar and imports coronary artery, its front end is provided with HDPE/ platinoiridita Marking ring, so that regulate the position at ingress pipe front end place under X-ray examination, make the front end of ingress pipe near the foreign body of intending removing, the tail end of ingress pipe is bell mouth shape, is convenient to insert thus arrest the collar.
during use, routinely the arteria coronaria guiding catheter is inserted in corresponding arteria coronaria, then coronary guide wire is inserted the inner chamber of guiding catheter, again the front end of ingress pipe is placed on coronary guide wire and along coronary guide wire and delivers to arteria coronaria, the degree of depth of regulating the ingress pipe insertion makes the front end of ingress pipe near the foreign body of intending removing, withdraw from coronary guide wire, if arresting the collar is made by the niti-shaped memorial alloy silk, utilizing the characteristics of niti-shaped memorial alloy will be placed in advance the collar of arresting the collar cooling under low temperature is shaped as and arrests bar shape in alignment, the horn mouth of collar end by the ingress pipe tail end inserted and move ahead along ingress pipe until stretch out the front end of ingress pipe, the collar reverts to annular under body temperature, at this moment, arresting bar by manipulation is enclosed within the collar on the foreign body of intending removing, then pull back and arrest bar, make the collar return gradually ingress pipe, the collar narrows down thereupon and attenuates, cover foreign body is in the inner clamped, foreign body is dragged to the ingress pipe front end mouth of pipe and when being stuck, draw outside the inner chamber of arteria coronaria guiding catheter together with ingress pipe arresting the collar, can be with foreign body.
This utility model is simple in structure, and is cheap, easy to use, can take out safely and effectively the foreign body in arteria coronaria.

Fig. 2 is the thimble structure schematic diagram of arresting of the present utility model.
Fig. 3 is ingress pipe structural representation of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings and embodiments, this utility model is described in detail.
This utility model is arrested the collar and is made by the tinsel of niti-shaped memorial alloy silk, stainless steel silk or other good springiness by arresting the collar and ingress pipe forms, and minute arrests bar 1 and the collar 2 two parts, arrests bar 1 and mutually is entwined by the B alloy wire of collar both sides; Ingress pipe is the good slender conduit of a pliability, the internal diameter of ingress pipe and the external diameter coupling of arresting bar 1, and the front end of ingress pipe is provided with HDPE/ platinoiridita Marking ring 3, and the tail end of ingress pipe is horn mouth 4, arrests the collar and inserts in ingress pipe thus.
Embodiment 1
The collar of arresting of the present utility model is made by the niti-shaped memorial alloy silk, and the collar 2 diameter 3 mm arrest long 110 cm of bar 1, diameter 2 F(3 F=1 mm); Ingress pipe is made by polyethylene, and long 80 cm, lumen diameter 2.4 F, external diameter 3 F, front end are provided with the long HDPE/ platinoiridita Marking ring 3 of 1 mm, and the maximum gauge of tail end horn mouth 4 is 3 mm, and horn mouth length is 4 mm.
This utility model can be made different specifications and models with the different and actual needs of arteria coronaria thickness according to the height of human body.
