Abstract
The utility model relates to an improved coronary artery balloon dilatation tube, which is characterized in that: a tube head distal end and a tube head proximal end are respectively connected with a saccule and an inner tube; two developing material marks are arranged respectively at the external surface of the inner tube distal end and right below two sides of the saccule; the sacuule proximal end is connected with an outer tube; the inner tube penetrates through a hollow cavity of the outer tube to form a dual-cavity structure; and the inner tube penetrates out from the opening of the outer tube proximal end; and the tail end of the outer tube proximal end is connected with a hypotube, the proximal end of which is connected with a handle. As the outer diameter of metal wires at the distal end of the hypotube gradually reduces from the proximal end to the distal end, the improved coronary artery balloon dilatation tube improves the overall conveying performance and the penetration performance of the tube and increases the controllable performance of doctors when in use.
Description
Technical field
This utility model relates to a kind of modified model coronary artery sacculus dilating catheter, particularly a kind of sacculus dilating catheter that is used for the percutaneous transluminal coronary angioplasty (PTCA) of interventional therapeutic technique.
Background technology
In recent years, the rise of interventional therapeutic technique is for better approach has been found in the treatment of cardiovascular disease.The heart disease interventional therapy is meant by the percutaneous catheter technology and carries out cardiopathic diagnosis and treatment, has obtained over 30 years developing rapidly and popularizing, and is described as one of most important contribution of 20th century medical development.Percutaneous transluminal coronary angioplasty is to adopt the percutaneous puncture technology that foley's tube is inserted into the coronary stricture place, and under the guiding and monitoring of medical imaging device, sacculus is expanded expansion, the cardiac catheter treatment technology that narrow positions expansion, myocardial flow are increased.
Existing coronary artery sacculus dilating catheter is because limitation and the structural defective on its material, make that in operation process foley's tube can't be by some serious arterial diseases or narrow zone that calcification caused, the ability of passing of conduit and tracking guidance capability are not strong, cause doctor's operating difficulties.
Summary of the invention
The purpose of this utility model is to improve on the existing coronary artery sacculus dilating catheter structure, technical deficiency, change the limitation of current material, a kind of modified model coronary artery sacculus dilating catheter is provided, strengthens the ability of passing of conduit integral body and follow the trail of guidance capability.
The purpose of this utility model is achieved in that a kind of modified model coronary artery sacculus dilating catheter, comprise the Tip far-end, the Tip near-end is connected with interior pipe with sacculus, interior pipe distal outer surface, two developing material labellings are installed under the border, sacculus both sides, balloon proximal is connected with outer tube, interior pipe runs through the outer tube cavity, form double cavity structure, interior pipe passes at outer tube proximal hole mouth place, the proximal outer tube end links to each other with the Hypo pipe, and Hypo pipe near-end is connected with handle, it is characterized in that: described Hypo pipe distal metal silk external diameter phases down from near-end to far-end.
Described Hypo pipe is the cavity metal tube, and distal metal silk cross section is cylindrical, and semicircle or crescent play a supportive role in the double lumen tube of interior pipe and outer tube composition.
Described Tip refers to pusher foremost, is made by the PEBAX composite, and is connected with laser weld between sacculus and the interior pipe.
Described sacculus is made by half compliance nylon material, and balloon diameter is 0.2-1.0mm/bar with pressure change rate, and balloon diameter is 1.0-5.0mm, and length of balloon is 6-40mm.
Pipe is made by the PEBAX composite in described, is that laser weld is connected with the connected mode of other parts.
Described developing material labelling is made by development metals such as gold or platinum, and the labelling peripheral diameter is 0.4-0.8mm, and labelling thickness is 0.3-0.7mm, and mark lengths is 0.4-1.5mm, is used to indicate the sacculus effective length.
Pipe passes at outer tube proximal hole mouth place in described, as the service aisle of seal wire.
Described outer tube is made by the PEBAX composite, is that laser weld is connected or thermal weld connects with the connected mode of other parts.
This utility model is owing to Hypo pipe distal metal silk external diameter phases down from near-end to far-end, improve the ability of passing of conduit thus and followed the trail of guidance capability, increased the doctor in use can be handling, by some serious arterial diseases or narrow zone that calcification caused the time, the ability of passing of conduit is higher than 95%.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is the structural representation of coronary artery sacculus dilating catheter of the present utility model.
Fig. 2 is the sketch map of Hypo pipe distal metal silk design.
Fig. 3 is a Hypo pipe distal metal silk partial enlarged drawing.
The specific embodiment
As shown in Figure 1, be the structural representation of a kind of quick exchange of this utility model (RX) coronary artery sacculus dilating catheter, this foley's tube comprises Tip1, sacculus 2, interior pipe 3, developing material labelling 4, outer tube 5, hole 6, Hypo pipe 7 and handle 8.Wherein: Tip1 and interior pipe 3 far-ends place in sacculus 2 distal chamber and are connected with laser weld, interior pipe 3 runs through sacculus 2 and outer tube 5,6 places, hole until outer tube 5 surfaces pass, connect by laser weld herein, sacculus 2 near-ends are connected by laser weld with outer tube 5 far-ends, outer tube 5 near-ends are managed 7 far-ends with Hypo and are connected by laser weld, and Hypo manages 7 near-ends and handle 8 and is connected by viscose glue, and Hypo manages 7 distal metal silk external diameters and phases down (as shown in Figure 2) from near-end to far-end.
