Description
Technical field
This utility model is related to a kind of a kind of new sacculus for treating cardiovascular disease of medical instruments field and expands
Open conduit.
Background technology
Cardiovascular and cerebrovascular disease be it is a kind of serious threaten the mankind, the commonly encountered diseases of particularly more than 50 years old middle-aged and elderly people health, entirely
The world dies from the number of cardiovascular and cerebrovascular disease every year and is up to 15,000,000 people, occupies the various causes of the death the first.Cardiovascular and cerebrovascular disease becomes
Human death's cause of disease highest number one killer.China dies from nearly 3,000,000 people of cardiovascular and cerebrovascular disease every year, accounts for our states annual total dead
The 51% of the cause of disease of dying.The topmost reason of artery disease is exactly atherosclerosiss, its cause blood vessel it is narrow with it is inaccessible,
Cause heart infarction, apoplexy and many peripheral blood vessels.
Treatment stricture of artery or inaccessible main modus operandi mainly have two kinds：Surgery is put up a bridge or by-pass operation, minimally invasive Jie
Enter treatment operation.Surgery put up a bridge or by-pass operation mainly by surgical operation by autogenous vein or artificial blood vessel replacing pathological changes blood
Pipe is unimpeded so as to recover blood flow.Minimally Interventional Therapy passes through to puncture femoral artery, radial artery etc., using seal wire, foley's tube and blood
The medical apparatus and instruments such as pipe holder are expanding lesion vesselses, unobstructed so as to recover blood flow.The Therapeutic Method of minimally invasive intervention is created due to patient
Hinder that little, recovery time is short, therapeutic effect is not inferior to surgical operation, now have been widely used for clinic.
The main usess of wherein foley's tube are to coordinate support to carry out the pre-expansion of lesion vesselses and rear expansion, narrow for simple
Pathological changes also treated by feasible simple balloon expandable.By studying to prior art, it has been found that current Clinical practice is all
For a kind of new sacculus dilating catheter of straight, when some bifurcated lesions blood vessels are treated, with the anatomical structure of bifurcated vessels not
Matching, be present certain.Such as the foley's tube for selecting the blood vessel larger with proximal diameter to match, dividing for distal end is may result in
Fork blood vessel overdistension, causes blood vessel excessive damage, and therapeutic effect is undesirable；As selected to match with the less blood vessel of distal diameter
Foley's tube, the lesion vesselses that are relatively large in diameter that may result in near-end fully do not expand, and do not reach preferable therapeutic effect.
Utility model content
The purpose of this utility model is to provide a kind of good a kind of new balloon expandable of rational in infrastructure, adherent effect to lead
Pipe, to solve a kind of existing new sacculus dilating catheter when bifurcated lesion vesselses are carried out with expansion operation, occurs to remote
End vasodilation transition expands not enough problem to proximal vessel.
This utility model is achieved through the following technical solutions：
A kind of new sacculus dilating catheter, including sacculus, inner tube, outer tube, developing mark, stress spread pipe and connection dress
Put, sacculus is connected with outer tube, inner tube is arranged in outer tube, outer tube is connected with attachment means by stress spread pipe, which is special
Levy and be：Described sacculus is tubular housing, and sacculus adopts step variable diameter design, and sacculus active section has two kinds of diameters, i.e., 2 sections not
It is connected by conical tube with the cylindrical tube of diameter, sacculus two ends are conical tube, one end and inner tube distal guide wire hole phase
Connection, the other end are connected with outer tube, and outer tube is cylindrical tube, sacculus and outer tube one closed cavity for connecting of formation, outer tube
It is connected with attachment means by stress spread pipe；Inner tube runs through outer tube cavity from sacculus sealing end points, and inner tube is provided with development
Labelling；Attachment means are arranged on the outside of outer tube, are provided with the hand-hole communicated with outer tube bore；
Preferably, the sacculus is connected the cylindrical tube of side with diameter greater than sacculus sealing end points side cylindrical tube with outer tube
Diameter；
Preferably, the diameter at the conical tube two ends is matched with the cylindrical tube diameter being connected；
Preferably, one end of said inner tube is located at the sealing end points of sacculus, and the opening of the other end is arranged on push rod end
Or on the wall of side；
Preferably, the sacculus is medical macromolecular materials；
Preferably, the medical macromolecular materials are nylon-type macromolecular material, modification of nylon family macromolecule material and height
Molecule copolymerization, blending or composite.
A kind of new sacculus dilating catheter that this utility model is provided, sacculus are divided into five sections, and middle three sections are the first circle
Column structure, the second cone section structure, the second cylindrical structure, and the second cylindrical structure with diameter greater than the first cylinder tie
The diameter of structure, the diameter of the first cylindrical structure are matched with the distal diameter of the second cone section structure, the second cylindrical structure
Diameter is matched with the proximal diameter of the second cone section structure, i.e. the overall structure of sacculus is that the diameter of the first cylindrical structure is little,
The diameter of the second cylindrical structure is big, meets the internal diameter change of human vas bifurcated sexually transmitted disease (STD) change.Therefore can avoid being expanded
During operation by the distal dilation transition of lower limb bifurcated lesion vesselses injured blood vessel or to lower limb bifurcated lesion vesselses
Proximal stent is not enough and impact expansion surgical effect, reduces the probability that postoperative thrombosis or restenosiss occur.Using segmentation knot
What structure design can improve that foley's tube passes through blood vessel or pathological changes passes through performance.
This utility model has advantages below：
1st, the unique profile arrangement of sacculus more conforms to the anatomical structure of bifurcated vessels, it is to avoid the mistake to distal vessels
Degree expansion causes to damage；
2nd, this patent is avoided simultaneously due to considering to reduce the overdistension to distal end lesion vesselses, selects less straight ball
Capsule, so as to the lesion vesselses expansion to near-end is not enough, causes curative effect to decline；
3rd, this patent makes balloon distal that there is less folding pressure to hold size, greatly due to the small size balloon design of distal end
Improve greatly foley's tube pass through blood vessel or pathological changes pass through performance；
4th, while the second cone section structure is located in the middle of the first cylindrical structure and the second cylindrical structure, play and seamlessly transit
Effect, can be brought into close contact with blood vessel when expansion operation is carried out, it is ensured that the safety and stability of operation.
