Abstract
The utility model discloses an interventional heart guide wire, which comprises at least three branch steel wires (3), wherein front end and back end of all branch steel wires are connected and fixed by anchor ears (1 and 4). The unfolded branch steel wire (3) is provided with an arch appearance. The connection of the anchor ears (1 and 4) with the branch steel wire is sealed by fixing layers (2 and 6). In addition, the back end of the branch steel wire (3) is connected with a trunk (5) through an anchor ear (4). The utility model has the advantages of reliably and safely adhering to heart operation part.
Description
Technical field
This utility model relates to a kind of fixture, especially relates to a kind of heart interventional guide wire of realizing the A/C position.
Background technology
In medical fields such as electrocardio interventional therapy, the tube chamber position in heart, the conduit of some type need recline reliably with the tissue of porch.Yet because the beating of heart is difficult to reclining of A/C and heart in the practical operation, is generally a straight seal wire at present and comes guide catheter to pass or arrive some privileged sites, this mode usually can not abut on the operative site reliably.
Summary of the invention
Be difficult to meet clinical needs in order to overcome existing seal wire, this utility model provide a kind of safe and reliable, abut in the seal wire of operative site reliably.
In order to achieve the above object, this utility model adopts following technical scheme: a kind of heart interventional guide wire, seal wire is made of the branch steel wire more than three, the rear and front end of all branch steel wires combines by anchor ear respectively and fixes, it is curved when the branch steel wire launches, anchor ear and branch steel wire junction point place are sealed by fixed layer, and the rear end of branch steel wire is connected with trunk by anchor ear.
Described branch steel wire front end connects by anchor ear can guiding steel wire.
This seal wire adopts the branch steel wire more than three to form, the two ends of all steel wires combine by anchor ear respectively and fix, curved when all steel wires launch (being gaily decorated basket shape launches), after the merging linearly, when moving to correct position after seal wire puts sleeve pipe, steel wire launches to play the effect of A/C position.Guiding steel wire is the softish metal of suitable length, and this design is that seal wire is worn out blood vessel or heart in avoiding operating, and guarantees safe and reliable; The anchor ear of branch steel wire front end is a metal material, is used for fixing branch steel wire leading portion.Fixed layer can be epoxy resin or plastic cement, and is smooth, smooth for the junction point at the slit between shutoff branch steel wire and the anchor ear and anchor ear and anchor ear place, guarantees the safety that seal wire uses; The anchor ear of branch steel wire rear end is a metal, and effect that this anchor ear played is connected for fixing branch steel wire and body trunk, the 2nd, prevent that other apparatuses from moving to leading portion from the continuation of body trunk.
The beneficial effects of the utility model are: can abut in reliably on the operative site, have advantages such as safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The structure of a kind of heart interventional guide wire of this utility model is as shown in Figure 1 and Figure 2: mainly be made of anchor ear 1, fixed layer 2, a plurality of branch steel wire 3, anchor ear 4, trunk 5, fixed layer 6, seal wire is made of the branch steel wire 3 more than three, the rear and front end of all branch steel wires 3 combines by anchor ear 1,4 fixing respectively, branch steel wire 3 launches the clock star arc, anchor ear 1,4 and branch steel wire 3 junction point places are by fixed layer 2,6 sealings, and the rear end of branch steel wire 3 is connected with trunk 5 by anchor ear 4.Be connected with guiding steel wire 7 at branch steel wire 3 front ends by anchor ear 1.Guiding steel wire 7 can be the softish metal or the other materials of suitable length, and this design is that seal wire is worn out blood vessel or heart in avoiding operating, and also can adopt the dome-type head.Anchor ear 1 is metal material or other materials, is used for fixing branch steel wire leading portion.Fixed layer 2, fixed layer 6 can be epoxy resin or plastic cement, for the slit between shutoff branch steel wire and anchor ear 1 or the anchor ear 4 and make anchor ear 1 or anchor ear 4 smooth, smooth.Anchor ear 4 is metal or other materials, the effect of anchor ear 4: one is being connected of fixing branch steel wire and body trunk 5, and two for preventing that other apparatuses (as sheathed catheter on the seal wire trunk time) from moving to leading portion from 5 continuation of body trunk.
Claims (2)
1, a kind of heart interventional guide wire, it is characterized in that: seal wire is made of the branch steel wire (3) more than three, the rear and front end of all branch steel wires (3) combines by anchor ear (1,4) fixing respectively, it is curved when branch steel wire (3) launches, anchor ear (1,4) is sealed by fixed layer (2,6) with branch steel wire (3) junction point place, and the rear end of branch steel wire (3) is connected with trunk (5) by anchor ear (4).
2, a kind of heart interventional guide wire according to claim 1 is characterized in that: be connected with guiding steel wire (7) at branch steel wire (3) front end by anchor ear (1).
