Description

One kind intervention conveying composite rope and preparation method thereof
Technical field
The present invention relates to technical field of medical instruments and other precision instruments manipulation field, more particularly to it is that a kind of intervention is defeated Send with composite rope and preparation method thereof.
Background technology
The fast development of interventional medicine apparatus, and precisely medical technology clinical practice so that for delivery instrument It is required that become more accurate, compact, effectively and safely stable operation.So that nervous centralis intervenes induction system as an example, microtubular distal end Existing this four specifications of ID 0.69mm, 0.56mm, 0.48mm, 0.43mm of internal diameter, hence for the apparatus of the traveling in conduit And conveying device proposes rigors that are higher, more accurate, can effectively manipulating, the apparatus conveyed and supporting delivery system System diameter is necessarily less than the internal diameter of microtubular;In order to be transported to the desired location in cerebral vessels, apparatus and conveying device are necessary For cerebral vessels multi-segmental and section is short, more diameter more piece three dimensional changes, bending complicated and changeable the characteristics of, possess into coming from Such as, excessively curved ability is strong, push-and-pull is smooth, forward and reverse the features such as turning round control freely.The existing all kinds of ganglioside GM_3 medical devices to appear on the market, disappear Change section apparatus, precision instruments manipulation intervention conveying device in, first, clinician to handling, excessively curved ability, release position Etc. also have improved expectation;Secondth, because of the miniaturization of delivery diameter, structure excessively complexity, the manufacture difficulty of existing conveying Greatly, risk is high;3rd, for the more compact nerve of diameter take the smaller apparatus such as bolt support, cerebral stents supporting conveying and Release, the optional apparatus in market are extremely limited;Expected conveying being actually needed in place can not still be met.It is it is therefore desirable to more smart The appearance of the conveying auxiliary products skilful, push characteristic, torque characteristic, excessively curved characteristic all have both.
The content of the invention
The present invention is in view of the deficienciess of the prior art, try hard to provide a kind of intervention conveying composite rope and its making side Method, there is simple in construction, sufficiently stable forward and reverse moment of torsion to pass on ability, superpower excessively curved ability, compliance and super-elasticity for it; In use, there is preferable push-and-pull ability, accurately torsion capacity, be also easy to batch steady production, system Make high reliability.
In order to solve the above technical problems, the technical scheme of this case is:One kind intervention conveying composite rope, it includes this Body, the body, which includes at least one, has super-elasticity or elastomeric middle core filaments and at least two periphery wrapping wires, described outer All wrapping wires are wrapped in outside middle core filaments, and the outer peripheral face of the body is surface contact structure.
Specifically, the middle core filaments have one.
Specifically, the periphery wrapping wire has five.
Specifically, the middle core filaments are superelastic NiTi alloy silk or high resiliency cochrome silk or linear elasticity alloy Silk.
Specifically, the periphery wrapping wire is stainless steel wire for spring or titanium alloy wire or nitinol alloy wire, has preferable bullet The combination of property, intensity and plasticity, is advantageous into and restricts, strengthens torsion and compliance.
Specifically, the cross section of the body is quincunx or polygon, outer peripheral face contact, can improve the moment of torsion conveyed Convey characteristics and push are with withdrawing stability.
Specifically, twist direction of the periphery wrapping wire in middle core filaments is left or right rotation.
Specifically, the lay pitch of the periphery wrapping wire in middle core filaments is 6~12 times of body external diameter.
Present invention also offers a kind of preparation method for intervening conveying composite rope, comprise the following steps:
(1) raw material are chosen:Selection and with super-elasticity or elastomeric middle core filaments and with high plasticity have concurrently Periphery wrapping wire elastomeric enough;The middle core filaments diameter is smaller than periphery wrapping wire diameter, improves the excessively curved energy of overall composite rope Power and toughness.
(2) twist thread with into rope:It is according to required twist direction and the defined lay pitch, periphery wrapping wire is uniform with selected raw material Composite rope is made around intermediate core filament winding;
(3) machine:Through die drawing or forge, it is ensured that the periphery for making composite rope is surface contact structure, obtains finished product.
Further, the periphery wrapping wire sectional area through die drawing or after forging is than the periphery wrapping wire sectional area through die drawing or before forging Small 0-30%.
After employing above-mentioned technical proposal, the composite rope applies to medical intervention field, especially in a diameter of submillimeter Induction system and withdraw in system and have obvious advantage, there is body simple in construction, sufficiently stable forward and reverse moment of torsion to pass on energy Power, superpower excessively curved ability, compliance and super-elasticity, in use, there is preferable push-and-pull ability, accurately distortional energy The advantages that power, complex lesions handling capacity.
