Abstract
The utility model relates to a 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 the tube head gradually reduces from the connection with the sacuule to the tail end, the tube wall gradually thins and the tube head is made of PEBAX material, the coronary artery balloon dilatation tube protects the blood vessel wall from being damaged due to the leading moving of the distal end of a conveyor while enhancing the overall penetration ability and the track leading ability of the tube.
Description
Technical field
This utility model relates to a kind of 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 to follow the trail of guidance capability not strong.
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; be used to strengthen the ability of passing of conduit integral body and follow the trail of guidance capability, the protection blood vessel wall can not move because of the guiding of carrier far-end and cause damage.
The purpose of this utility model is achieved in that a kind of 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, and 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: the Tip external diameter is from phasing down with sacculus junction to end, and tube wall is attenuation gradually.
Described Tip refers to pusher foremost, is made by the PEBAX composite, and length is 0.5-1.5mm, and diameter taper is 2-15 °, and is connected by 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.
Described Hypo pipe is the cavity metal tube, and distal metal silk cross section is a cylinder, and semicircle or selenodont play a supportive role in the double lumen tube of interior pipe and outer tube composition.
This utility model since the Tip external diameter from phasing down with sacculus junction to end; tube wall is attenuation gradually; therefore having strengthened conduit integral body passes ability and follows the trail of guidance capability; the laser weld connected mode of coupling part can be protected blood vessel wall can not move because of the guiding of carrier far-end and cause damage; thereby 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 local enlarged diagram of Tip.
The specific embodiment
As shown in Figure 1, structural representation for a kind of quick exchange of the present 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, use laser weld; Interior pipe 3 distal outer surface, two developing material labellings 4 are installed under the border, sacculus 2 both sides, sacculus 2 near-ends are connected with outer tube 5 usefulness laser weld, and interior pipe 3 runs through sacculus 2 and outer tube 5, pass until 6 places, hole on outer tube 5 surfaces, service aisle as seal wire, outer tube 5 near-ends manage with Hypo that 7 far-ends carry out laser or heat seal is connected, and Hypo manages 7 near-ends and carries out viscose glue with handle 8 and be connected, Tip from the sacculus junction to terminal, external diameter phases down, tube wall attenuation gradually (as shown in Figure 2).
