Abstract
The present invention relates to one kind of angiography catheter with controllable tip direction. The angiography catheter has one cavity extending along the side wall, one drawing wire set inside the cavity, tip inclined towards the cavity side and connected to the drawing wire, and one button connected to the tail side wall and connected to the end of the drawing wire through the cavity. The present invention has simple structure, no obstruction on operation, and capacity of reducing the diameter to below 2 mm for small blood vessel use.
Description
Technical field
The present invention relates to a kind of interventional operation equipment, the controlled angiography catheter of particularly a kind of tip direction.
Background technology
The angiography catheter that often uses in the medical operating is varied, raw materials such as useful polyethylene or polrvinyl chloride are made, and the conduit bore varies, and profile also has nothing in common with each other, the purpose of using is exactly to arrive diseased region quickly and accurately, so that further intervene operation treatment.But in clinical practice; usually can be unusual because of the blood vessel traveling, buckling of vessel, vessel lumen is narrow and the reason such as uncontrollable of angiography catheter, seal wire; make conduit and the seal wire arrival diseased region of can not achieving one's goal, thereby brought difficulty for next step intervene operation treatment.
Before the present invention, in order to address this problem, have a plurality of holes are set on duct wall, many draught lines are put into different holes, catheter tip adopts multistage movable tube coupling, and hinge joint connects.Draught line is connected with pipe end medicated cap on the tip, reaches moving of control catheter tip by tight, loose draught line, arrives diseased region.The defective of this method is very obvious, and the one, a plurality of vestibules, many draught lines are arranged, be difficult to big conduct at the small-caliber vascular intracavity.The 2nd, parts are too many, and many draught lines, more piece activity tube coupling, pipe end medicated cap etc. are arranged, and also are difficult to be suitable at the small-caliber vascular intracavity; And parts are many more, operate complicatedly more, also are not easy accurately control and arrive diseased region, are out of order easily.The 3rd, many draught lines are controlled by hand, and mutual coordination is got up pretty troublesome, also is difficult to accurate control accuracy, hands one pine, and catheter tip location just may move.The 4th, so many parts, labyrinth can't reach under the situation of lumen of vessels diameter less than 2mm it and use.Therefore this controllable direction conduit can only be used for gastrointestinal and Tracheography, and can not be applicable in the lumen of vessels.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned defective, design, the controllable simple and suitable angiography catheter of a kind of tip direction of development.
Technical scheme of the present invention is:
The angiography catheter that tip direction is controlled, its major technique is characterised in that offers a vestibule on the angiography catheter sidewall, this vestibule extends along sidewall always, the catheter lumen of this vestibule and angiography catheter itself separates, draught line is placed therebetween, and the angiography catheter tip is to the vestibule lopsidedness, and the draught line top is connected with angiography catheter tip to the vestibule lopsidedness, sidewall at the angiography catheter afterbody connects knob, and the draught line end is connected with knob through vestibule.
Advantage of the present invention and effect are that duct wall only places a draught line, so that the conduit bore can be as much as possible little; Catheter tip just can be adjusted the direction of catheter tip slightly to the direction bending that the draught line vestibule is arranged during draught line of tractive; Draught line is drawn from angiography catheter tail end sidewall, draw tail end and connect a knob, the tractive draught line is adjusted the catheter tip direction, tightens knob, but with regard to the fixed traction line, simultaneously the A/C tip direction accurately and after adjusting can not move, and is simple in structure, parts are few, simultaneously knob is at side, the patient's subsequent operation of might as well being in the way.Because therefore the built-in single draught line of areole can be made into diameter 2mm and following angiography catheter conveniently enters small-caliber vascular.
Description of drawings
Fig. 1---structural principle sketch map of the present invention.
The specific embodiment
As shown in Figure 1, integral body is an angiography catheter, and angiography catheter tip 1 is to vestibule 2 lopsidedness, and angle is more than 5 degree, and best angle is between 20～30 degree, and this example is 25 degree; On the sidewall of conduit, along duct wall one hole is set, form vestibule 2; In vestibule 2, place draught line 4, one end of draught line 4 is connected with catheter tip 1 towards vestibule 2 lopsidedness, and the other end of draught line 4 is connected with knob 6 through vestibule 2, is drawn by knob 6, knob 6 is arranged on the sidewall of catheter tail, forms an angle with catheter-shaped; And the catheter lumen 3 of draught line 4 residing vestibules 2 and angiography catheter itself separates, and is independent of each other.
During application, in the angiography catheter intravasation, near the elder generation arrival lesion vessels position, the angiography catheter tip 1 of inclination is towards lesion vessels; The tractive draught line 4 then, and certain pliability of utilizing conduit itself to have makes catheter tip 1 accurately towards the blood vessel that will enter, and screws knob 6 again, fixed traction line 4, the direction of also promptly having fixed catheter tip 1; Again seal wire (omit among the figure, do not draw) is entered lesion vessels along catheter lumen 3 and angiography catheter tip 1, enter next step support placement or balloon expandable treatment again; When withdrawing from conduit after the end, first rotary knob 6 unclamps draught line 4, makes catheter tip 1 be returned to original form, and conduit is withdrawed from from blood vessel smoothly.The diameter that the tube chamber of draught line and vestibule, angiography catheter lumps together can be less than 2mm, to be suitable for angiographic applications.
Claims (5)
