Description
Technical field
This utility model relates to medical devices field, particularly a kind of hypotube.
Background technology
Hypotube refers to the metal tube of near-end in sacculus dilating catheter (one end that distance operator is near), and can enter human body in interventional procedure, material is generally medical grade 304 rustless steel.In Stent, hypotube is a part for induction system.Hypotube superior function directly has influence on the success rate of operation, because his to be operator push whole sacculus dilating catheter enter in patient body unique force application part, is also the ingredient that in whole sacculus dilating catheter, intensity is maximum.
The leading indicator of current evaluation hypotube performance has: the power that pushes transmit performance, buckle resistance, can the supportive of torsion, compliance, tube chamber size and the far-end body of rod to sacculus dilating catheter.On market today, the design of hypotube is varied, specifically variant in the following aspects: external surface coating, diameter, wall thickness, length and far-end (one end that distance operator is far away) form.Wherein the structure of far-end form is the most complicated, design difference is maximum.And far-end form determines whether propelling movement power can be sent to far-end from the near-end of hypotube to greatest extent, and whether can reach the transition smoothly that compliance increases progressively by near-end to far-end, hypotube entirety keeps good bend resistance performance simultaneously.
Existing hypotube far-end form can be divided three classes substantially: lining wire type, notch cuttype and cutting-type.
But lining wire type is without seamlessly transitting, proximally body change large and suddenly, simultaneously because serve as a contrast silk softness, it is also poor to the enabling capabilities of the far-end body of rod of sacculus dilating catheter to far-end lining silk in buckle resistance and compliance.
Notch cuttype hypotube limits by the length of pipe diameter and ladder part, and usual changeover portion is shorter, and the slow gradual change that cannot realize submissive performance also cannot support the body of rod of guidewire port more distal portions, and the propelling movement power which limits hypotube transmits performance.And the hypotube of notch cuttype takies the distal rod intracoelomic cavity large percentage of sacculus dilating catheter at guidewire port position, easily affect the full of sacculus dilating catheter and pumpback time (need to inject contrast agent liquid in the far-end body of rod tube chamber of sacculus dilating catheter and make balloon expandable in interventional procedure).
Cutting-type does not affect the conduction of axial force while of improving the pliability of body radial direction by the cutting doing the design of different lines at hypotube body.Combinationally use, because cutting process can only be carried out on complete body with coordinate his needs of the hypotube of cutting-type and the notch cuttype of the far-end body of rod of sacculus dilating catheter to realize.Relative to notch cuttype, the hypotube of cutting-type proximally arrives far-end transitions smooth in buckle resistance and compliance, but cannot well propelling movement power be delivered on the body of rod than guidewire port more far-end equally, also appear in the distal rod intracoelomic cavity large percentage that guidewire port position takies sacculus dilating catheter, easily affect the problem of the full of sacculus dilating catheter and pumpback time.
In sum, although far-end form is that the hypotube of cutting-type can accomplish that hypotube proximally arrives far-end transitions smooth in buckle resistance and compliance in existing hypotube, the axial thrust be applied on the near-end (body) of hypotube still cannot be sent on the far-end body of rod of sacculus dilating catheter by it.
