Abstract
The invention relates to a balloon catheter structure capable of being bent directionally. The balloon catheter structure comprises a balloon (2) and a catheter (1) which is arranged inside the balloon in a penetrating mode. Developing marks (4) are arranged at the positions, corresponding to the two ends of the balloon (2), of the catheter, and gas guide holes (6) are formed in the catheter inside a cavity of the balloon (2). The balloon catheter structure capable of being bent directionally is characterized in that a section of linear limiting piece (5) is arranged on one side of the catheter placed inside the balloon body of the balloon, and the two ends of the linear limiting piece are fixed to the joint parts of the balloon (2) and the catheter (1) respectively. The curvature of the balloon can be mutually matched with the curvature of a blood vessel to a certain extent by the way that the linear limiting piece with a certain length is selected to be arranged, and obviously the targeted matching is extremely favorable to propulsion and expansion of the balloon body of the balloon in the curved blood vessel.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, refer in particular to a kind of orientable bending foley's tube, be applicable under X-ray non-vascular tract dilation therapy narrow in human organ.
Background technology
Intravascular Interventional Treatment has become less invasive techniques means conventional in human vas pathological changes, and the sacculus dilating catheter generally used at present all has a balloon-expandable, developing mark, flexible conduit to form.
The such sacculus dilating catheter generally used at present is made up of balloon-expandable far-end and inner catheter remote extension section hot melt due to catheter proximal end, especially sacculus and inner catheter by single macromolecular material (as polyurethane, nylon, polypropylene, polyethylene, silica gel etc.) make.
In addition, in traditional foley's tube, the bending of general sacculus is uncontrollable, and sacculus degree of crook increases along with the increase of balloon pressure, because when carrying out the expansion having certain bending blood vessel, sometimes the DeGrain expanded, the problem that may bring is: 1, the bending degree of crook not reaching or exceed blood vessel of sacculus under the pressure needed; 2, when degree of crook meets the radius of curvature of blood vessel, balloon pressure does not reach again the requirement needing blood vessel dilating, brings certain uncertainty to operation.
Summary of the invention
Object of the present invention: be intended to propose one and have certain automatic bending functional ball ductus bursae, can adapt to have the convenience of propelling in the blood vessel of certain flexibility and expansion
This orientable bending foley's tube, the conduit 1 comprising a sacculus utricule 2 and be set in sacculus utricule, the conduit corresponding position at described sacculus utricule 2 two ends is provided with developing mark 4, and conduit in sacculus utricule 2 cavity is provided with gas port 6, it is characterized in that: be provided with one section of wire locating part 5 in the side of the conduit being positioned at sacculus utricule, the two ends of described wire locating part are separately fixed at the joint portion of described sacculus utricule 2 and conduit 1.
The length of described wire locating part 5 is 20-80mm.
The length of described sacculus utricule 2 is 20-80mm.
Described catheter tip is soft head.
What propose according to above technical scheme thisly has certain automatic bending functional ball ductus bursae, by the wire locating part of option and installment certain length, the flexibility of sacculus can be formed certain mating mutually with the flexibility of blood vessel.Obviously this cooperation shot the arrow at the target is very favourable for the expansion of solution sacculus in curved blood vessel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-conduit 2-sacculus utricule 3-catheter tip 4-developing mark 5-wire locating part 6-gas port.
Detailed description of the invention
This orientable bending foley's tube as shown in the figure, it is a kind of inventive improvements to existing foley's tube.
This orientable bending foley's tube, the conduit 1 that it comprises a sacculus utricule 2 and is set in sacculus utricule, the conduit relevant position at described sacculus utricule 2 two ends goes out to be provided with developing mark 4, and conduit in sacculus utricule 2 cavity is provided with gas port 6, it is characterized in that: be provided with one section of wire locating part 5 in the side of the conduit being positioned at sacculus utricule, the two ends of described wire locating part 5 are separately fixed at the joint portion of described sacculus utricule 2 and conduit 1.
The length of described wire locating part 5 is 20-80mm.
The length of described sacculus utricule 2 is 20-80mm.
Described catheter tip is soft head.
By on the basis of traditional foley's tube, one section of non-telescoping, that there is certain length wire locating part is added in the side of the conduit being positioned at sacculus utricule, in the process expanded after sacculus pressurized, sacculus utricule axially slightly can increase along with the increase of pressure, but under the effect of the wire locating part of radial direction setting, this side can not correspondingly be extended, therefore cause sacculus bending to this direction, and the radius of curvature that sacculus utricule bends determines according to the length of wire locating part, the radius of curvature that the shorter then sacculus of length of locating part is bending is larger.
In actual use: foley's tube as shown in Figure 1, be welded with one in the centre of sacculus utricule 2 and there is the macromolecule tubing of some strength as conduit 1, this macromolecule tubing is by gas port that tube wall is arranged 6 and sacculus utricule 2 UNICOM, form pressurizing channel, and the position being positioned at sacculus utricule 2 at conduit two ends is respectively provided with a developing mark 4, determines the position of sacculus utricule when being convenient to Clinical practice.Described wire locating part 5 is fixed on the side of sacculus utricule radial direction, when utricule inflating pressure, the utricule of this side can not extend with the increase of utricule pressure thereupon, the utricule at offside position then extends under the effect of the blowing pressure, thus causes whole sacculus utricule to form certain bending.
Carrying out blood vessel dilating operation consent, clinician first can roughly judge the bending sacculus needing what radius of curvature under the help of the developing agent of X-ray, and then selects the sacculus of corresponding radius of curvature specification; Thisly selecting targetedly, is very favourable for the propelling of solution sacculus in curved blood vessel.
In actual fabrication: connect between sacculus utricule and polymer tube and non-telescoping spacing line and all use the mode of laser weld to complete, under laser energy, can there is melting in polymer tube, thus the two ends of spacing line line are fixed on the position of the junction of sacculus utricule and polymer tube.
Owing to requiring that spacing line has not ductile characteristic, and intervention human body contacts with human body fluid, therefore the material of spacing line is defined as metal material (the NiTi B alloy wire such as after Overheating Treatment), macromolecular material (such as polyethylene, polyethylene terephthalate ...) according to the general bending degree of human vas, the length of spacing line distributes at 20mm-80mm.
